Parenteral medications<\/strong> enter the body by injection through\u00a0the tissue and circulatory system. Injection medications are absorbed more quickly and are used with patients who are nauseated, vomiting, restricted from taking oral fluids, or unable to swallow. Parenteral medications can be effective and safe when prepared and administered correctly. However, because they are invasive and absorbed readily and quickly into the body, there are numerous risks associated with administering them (Perry et al., 2014).\r\n\r\nThere are four routes for parenteral medications (also see Figure 7.1). Each type of injection requires a specific skill set to ensure the medication is prepared properly and administered into the correct location (Perry et al., 2014). The four types of injections are:\r\n

Tables 7.1 to 7.4 address specific practices to eliminate safety hazards to patients and health care workers.\r\n

    Preventing Infection During an Injection<\/h2>\r\nAccording to Seigel et al, (2007), research has shown that unsafe injection practices have resulted in patient exposure to infections leading to outbreaks of infectious diseases. These unnecessary exposures were the result of deficient health care practices. Injectable medications must be given in a safe manner to maintain sterility of equipment and prevent the transmission of infectious diseases between patients and health care workers. Table 7.1 summarizes how to prevent an infection during an injection.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

    Safe Medication Administration<\/h2>\r\nMedication errors have a substantial impact on health care in Canada (Butt, 2010). When preparing and administering medication, and assessing patients after receiving medication, always follow agency policy to ensure safe practice. Review Table 7.2 for guidelines for safe medication administration.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

    Be vigilant when preparing medications.<\/td>\r\nAvoid distractions. Some agencies have a no-interruption zone (NIZ), where health care providers can prepare medications without interruptions.<\/td>\r\n<\/tr>\r\n
    Check for allergies.<\/td>\r\nAlways ask patient about allergies, types of reactions, and severity of reactions.<\/td>\r\n<\/tr>\r\n

    Assessment comes before medication administration.<\/td>\r\nAll medications require an assessment (review of lab values, pain, respiratory or cardiac assessment, etc.) prior to medication administration to ensure the patient is receiving the correct medication for the correct reason.<\/td>\r\n<\/tr>\r\n
    Be diligent in all medication calculations.<\/td>\r\nErrors in medication calculations have contributed to dosage errors, especially when adjusting or titrating dosages.<\/td>\r\n<\/tr>\r\n
    Avoid reliance on memory; use checklists and memory aids.<\/td>\r\nSlips in memory are caused by lack of attention, fatigue, and distractions. Mistakes are often referred to as attentional behaviours, and they account for most errors in health care. If possible, follow a standard list of steps for every patient.<\/td>\r\n<\/tr>\r\n
    Communicate with your patient before and after administration.<\/td>\r\nProvide information to patient about the medication before administering it. Answer questions regarding usage, dose, and special considerations. Give the patient the opportunity to ask questions. Include family members if appropriate.<\/td>\r\n<\/tr>\r\n
    Avoid workarounds.<\/td>\r\nA workaround\u00a0<\/strong>is a process that bypasses a procedure, policy, or problem in a system. For example, nurses may \"borrow\" a medication from another patient while waiting for an order to be filled by the pharmacy. These workarounds fail to follow agency policies that ensure safe medication practices.<\/td>\r\n<\/tr>\r\n
    Ensure medication has not expired.<\/td>\r\nMedication may be inactive if expired.<\/td>\r\n<\/tr>\r\n
    Always clarify an order or procedure that is unclear.<\/td>\r\nAlways ask for help whenever you are uncertain or unclear about an order. Consult with the pharmacist, charge nurse, or other health care providers and be sure to resolve all questions before proceeding with medication administration.<\/td>\r\n<\/tr>\r\n
    Use available technology to administer medications.<\/td>\r\nBar-code scanning (eMAR) has decreased errors in administration by 51%, and computerized physician orders have decreased errors by 81%. Technology has the potential to help decrease errors. Use technology when administering medications, but be aware of technology-induced errors.<\/td>\r\n<\/tr>\r\n
    Report all near misses, errors, and adverse reactions.<\/td>\r\nReporting allows for analysis and identification of potential errors, which can lead to improvements and sharing of information for safer patient care.<\/td>\r\n<\/tr>\r\n
    Be alert to error-prone situations and high-alert medications.<\/td>\r\nHigh-alert medications are those\u00a0that are most likely to cause significant harm, even when used as intended.\u00a0The most common high-alert medications are\u00a0anticoagulants, narcotics and opiates, insulins, and sedatives. The types of harm most commonly associated with these medications include hypotension, respiratory depression, delirium, bleeding, hypoglycemia, bradycardia, and lethargy.<\/td>\r\n<\/tr>\r\n

    Promoting Safety and Comfort of a Patient During an Injection<\/h2>\r\nInjections can be given safely and effectively, and harm can be prevented if proper injection technique is used. Most complications related to injections are associated with intramuscular injections, but may occur with any route. Complications can occur when an incorrect site is used, or with an inappropriate depth or rate of injection (Malkin, 2008). To promote patient safety and comfort during an injection, review the guidelines in Table 7.3.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

    Correct needle<\/td>\r\n\r\n

    For injections, use a sharp, beveled needle and place bevel side up. Change the needle if liquid coats the shaft of the needle. Correct needle length allows for correct delivery of medication into the correct site and can reduce complications such as abscesses, pain, and bruising. Needle selection should be based on size of patient, gender, injection site, and amount of medication injected. Women tend to have more adipose tissue around the buttocks and deltoid fat pad, which means more than half the injections given do not reach the proper IM depths in women. Large bore needles have been found to reduce pain, swelling, and redness after an injection, as less pressure is required to depress the plunger.<\/p>\r\n<\/td>\r\n<\/tr>\r\n

    Proper angle of insertion and removal (see Figure 7.1<\/a>)<\/td>\r\n\r\n

    Inserting the needle at the proper angle (depending on the type of injection) and entering the skin smoothly and quickly can reduce pain during injection. Hold the syringe steady once the needle is in the tissue to prevent tissue damage. Withdraw the needle at the same angle used for insertion. The angle for an IM injection is 90 degrees. With all injections, the needle should be inserted all the way up to the hub. Holding the syringe like a dart prevents the medication from being injected during insertion of needle. Removing residue (medication on the tip of the needle) has been shown to reduce pain and discomfort. To remove residue from the needle, change needles after preparation and before administration.<\/p>\r\n<\/td>\r\n<\/tr>\r\n

    Patient position<\/td>\r\nThe patient's position may affect their perception of pain. Proper position will also facilitate proper landmarking of the site. For IM injections, for example, the ventrogluteal site has the greatest muscle thickness and is free of nerves and blood vessels, with a small layer of fat.<\/td>\r\n<\/tr>\r\n
    Relaxation technique and distraction methods<\/td>\r\nPosition the patient's limbs in a relaxed, comfortable position to reduce muscle tension. For example, lying prone may help a patient relax prior to an IM injection. If giving a deltoid IM injection, have the patient relax the arm by placing the hand in the lap. If a patient is receiving an IM injection in the vastus lateralis or ventrogluteal site, encourage the patient to gently point toes outwards to relax the muscle. Relaxation skills of the health care provider will help decrease the patient's anxiety-heightened pain. If possible, divert the patient's attention away from the injection procedure.<\/td>\r\n<\/tr>\r\n
    Pre-medication, if required<\/td>\r\nTo decrease pain upon insertion, a vapocoolant spray, topical anesthetic, or wrapped ice may be placed on the insertion site for a minute prior to injection. For IM injections, two studies found that applying pressure to the injection site for 10 seconds before the injection reduced pain. This data supports the gate theory of pain control.<\/td>\r\n<\/tr>\r\n
    Z-track method for IM injections<\/td>\r\nSome research shows that the Z-track technique results in reduced pain and complications, and fewer injection lesions. However, other research shows that Z-track injections result in more pain and bleeding at the injection site. (See 7.4 Intramuscular Injections for more on the Z-track method.)<\/td>\r\n<\/tr>\r\n
    Administration rate<\/td>\r\nResearch has found that administrating medications at 10 seconds per ml is an effective rate for IM injections. Increasing the rate to 20 seconds per ml did not show any reduction in pain. Always review drug administration rate as per pharmacy or manufacturer\u2019s recommendations.<\/td>\r\n<\/tr>\r\n
    Gentle touch with insertion sites<\/td>\r\nGently apply a dry sterile gauze to the site after the injection. Rotate injection sites to prevent the development of indurations and abscesses.<\/td>\r\n<\/tr>\r\n
    Aspiration with IM injections<\/td>\r\nReview the latest research regarding the utility of aspirating IM injections. There is lack of strong evidence to support the technique of aspiration with IM injections.<\/td>\r\n<\/tr>\r\n

    Preventing Needle-Stick Injuries<\/h2>\r\nHealth care providers can be at risk for needle-stick injuries in any health care setting. The most common places for needle-stick injuries to occur are in the operating room and patient rooms. Tasks that place the health care provider at risk include recapping needles and mishandling IV lines.

    Preparing Medications from Ampules and Vials<\/h2>\r\nSpecific equipment, such as syringes and needles, is required to prepare and administer parenteral medications. The selection of the syringe and needle is based on the type and location of injection; amount, quality, and type of medication; and the body size of the patient. Many syringes come with needleless systems or needles with safety shields to prevent injuries (Perry et al., 2014).\u00a0Aseptic technique is paramount to the preparation and administration of these medications.\r\n\r\nParenteral medications are supplied in sterile vials, ampules, and prefilled syringes. Ampules <\/strong>are glass containers in 1 ml to 10 ml sizes that\u00a0hold a single dose of medication in liquid form. They are made of glass and have a scored neck to indicate where to break the ampule (see Figure 7.2). Medication is withdrawn using a syringe and a filter needle. A blunt fill needle with filter (see Figure 7.3) must be used when withdrawing medication to prevent glass particles from being drawn up into the syringe (see Figure 7.4). Never use a filter needle to inject medication (Perry et al.,\u00a02014).\r\n\r\n[caption id=\"attachment_6661\" align=\"aligncenter\" width=\"300\"]\"Preparing<\/a> Figure 7.2 Breaking open an ampule[\/caption]\r\n\r\n[caption id=\"attachment_6822\" align=\"aligncenter\" width=\"300\"]\"Oct<\/a> Figure 7.3 Blunt fill needle with filter[\/caption]\r\n\r\n[caption id=\"attachment_6823\" align=\"aligncenter\" width=\"300\"]\"Using<\/a> Figure 7.4 Using a blunt fill needle with filter with an ampule[\/caption]\r\n\r\n

      Parenteral refers to the path by which medication comes in contact with the body. Parenteral medications<\/strong> enter the body by injection through\u00a0the tissue and circulatory system. Injection medications are absorbed more quickly and are used with patients who are nauseated, vomiting, restricted from taking oral fluids, or unable to swallow. Parenteral medications can be effective and safe when prepared and administered correctly. However, because they are invasive and absorbed readily and quickly into the body, there are numerous risks associated with administering them (Perry et al., 2014).<\/p>\n

      There are four routes for parenteral medications (also see Figure 7.1). Each type of injection requires a specific skill set to ensure the medication is prepared properly and administered into the correct location (Perry et al., 2014). The four types of injections are:<\/p>\n

        Preventing Infection During an Injection<\/h2>\n

        According to Seigel et al, (2007), research has shown that unsafe injection practices have resulted in patient exposure to infections leading to outbreaks of infectious diseases. These unnecessary exposures were the result of deficient health care practices. Injectable medications must be given in a safe manner to maintain sterility of equipment and prevent the transmission of infectious diseases between patients and health care workers. Table 7.1 summarizes how to prevent an infection during an injection.<\/p>\n\n\n\n\n\n\n\n\n\n\n

Avoid letting the needle touch unsterile surfaces such as the outer edges of the ampule or vial, surface of the needle cap, or counter. Always keep the needle covered with a cap when not in use, and use the scoop-cap method to avoid needle-stick injuries. Avoid touching the length of the plunger. Keep the tip of the syringe sterile by covering with a cap or needle.<\/p>\n

        Safe Medication Administration<\/h2>\n

        Medication errors have a substantial impact on health care in Canada (Butt, 2010). When preparing and administering medication, and assessing patients after receiving medication, always follow agency policy to ensure safe practice. Review Table 7.2 for guidelines for safe medication administration.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

        		\n

        \u00a0Additional Information<\/h4>\n<\/td>\n<\/tr>\n

        Be vigilant when preparing medications.<\/td>\nAvoid distractions. Some agencies have a no-interruption zone (NIZ), where health care providers can prepare medications without interruptions.<\/td>\n<\/tr>\n
        Check for allergies.<\/td>\nAlways ask patient about allergies, types of reactions, and severity of reactions.<\/td>\n<\/tr>\n
        Use two patient identifiers at all times. Always follow agency policy for patient identification.<\/td>\nUse at least two patient identifiers before administration AND compare against the medication administration record (MAR).<\/td>\n<\/tr>\n
        Assessment comes before medication administration.<\/td>\nAll medications require an assessment (review of lab values, pain, respiratory or cardiac assessment, etc.) prior to medication administration to ensure the patient is receiving the correct medication for the correct reason.<\/td>\n<\/tr>\n
        Be diligent in all medication calculations.<\/td>\nErrors in medication calculations have contributed to dosage errors, especially when adjusting or titrating dosages.<\/td>\n<\/tr>\n
        Avoid reliance on memory; use checklists and memory aids.<\/td>\nSlips in memory are caused by lack of attention, fatigue, and distractions. Mistakes are often referred to as attentional behaviours, and they account for most errors in health care. If possible, follow a standard list of steps for every patient.<\/td>\n<\/tr>\n
        Communicate with your patient before and after administration.<\/td>\nProvide information to patient about the medication before administering it. Answer questions regarding usage, dose, and special considerations. Give the patient the opportunity to ask questions. Include family members if appropriate.<\/td>\n<\/tr>\n
        Avoid workarounds.<\/td>\nA workaround\u00a0<\/strong>is a process that bypasses a procedure, policy, or problem in a system. For example, nurses may “borrow” a medication from another patient while waiting for an order to be filled by the pharmacy. These workarounds fail to follow agency policies that ensure safe medication practices.<\/td>\n<\/tr>\n
        Ensure medication has not expired.<\/td>\nMedication may be inactive if expired.<\/td>\n<\/tr>\n
        Always clarify an order or procedure that is unclear.<\/td>\nAlways ask for help whenever you are uncertain or unclear about an order. Consult with the pharmacist, charge nurse, or other health care providers and be sure to resolve all questions before proceeding with medication administration.<\/td>\n<\/tr>\n
        Use available technology to administer medications.<\/td>\nBar-code scanning (eMAR) has decreased errors in administration by 51%, and computerized physician orders have decreased errors by 81%. Technology has the potential to help decrease errors. Use technology when administering medications, but be aware of technology-induced errors.<\/td>\n<\/tr>\n
        Report all near misses, errors, and adverse reactions.<\/td>\nReporting allows for analysis and identification of potential errors, which can lead to improvements and sharing of information for safer patient care.<\/td>\n<\/tr>\n
        Be alert to error-prone situations and high-alert medications.<\/td>\nHigh-alert medications are those\u00a0that are most likely to cause significant harm, even when used as intended.\u00a0The most common high-alert medications are\u00a0anticoagulants, narcotics and opiates, insulins, and sedatives. The types of harm most commonly associated with these medications include hypotension, respiratory depression, delirium, bleeding, hypoglycemia, bradycardia, and lethargy.<\/td>\n<\/tr>\n
        If a patient questions or expresses concern regarding a medication,\u00a0stop and do not administer it.<\/td>\nIf a patient questions a medication, stop and explore the patient’s concerns, review the physician’s order, and, if necessary, notify the practitioner in charge of the patient.<\/td>\n<\/tr>\n

        Promoting Safety and Comfort of a Patient During an Injection<\/h2>\n

        Injections can be given safely and effectively, and harm can be prevented if proper injection technique is used. Most complications related to injections are associated with intramuscular injections, but may occur with any route. Complications can occur when an incorrect site is used, or with an inappropriate depth or rate of injection (Malkin, 2008). To promote patient safety and comfort during an injection, review the guidelines in Table 7.3.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n

        Correct needle<\/td>\n\n

        For injections, use a sharp, beveled needle and place bevel side up. Change the needle if liquid coats the shaft of the needle. Correct needle length allows for correct delivery of medication into the correct site and can reduce complications such as abscesses, pain, and bruising. Needle selection should be based on size of patient, gender, injection site, and amount of medication injected. Women tend to have more adipose tissue around the buttocks and deltoid fat pad, which means more than half the injections given do not reach the proper IM depths in women. Large bore needles have been found to reduce pain, swelling, and redness after an injection, as less pressure is required to depress the plunger.<\/p>\n<\/td>\n<\/tr>\n

        Proper angle of insertion and removal (see Figure 7.1<\/a>)<\/td>\n\n

        Inserting the needle at the proper angle (depending on the type of injection) and entering the skin smoothly and quickly can reduce pain during injection. Hold the syringe steady once the needle is in the tissue to prevent tissue damage. Withdraw the needle at the same angle used for insertion. The angle for an IM injection is 90 degrees. With all injections, the needle should be inserted all the way up to the hub. Holding the syringe like a dart prevents the medication from being injected during insertion of needle. Removing residue (medication on the tip of the needle) has been shown to reduce pain and discomfort. To remove residue from the needle, change needles after preparation and before administration.<\/p>\n<\/td>\n<\/tr>\n

        Patient position<\/td>\nThe patient’s position may affect their perception of pain. Proper position will also facilitate proper landmarking of the site. For IM injections, for example, the ventrogluteal site has the greatest muscle thickness and is free of nerves and blood vessels, with a small layer of fat.<\/td>\n<\/tr>\n
        Relaxation technique and distraction methods<\/td>\nPosition the patient’s limbs in a relaxed, comfortable position to reduce muscle tension. For example, lying prone may help a patient relax prior to an IM injection. If giving a deltoid IM injection, have the patient relax the arm by placing the hand in the lap. If a patient is receiving an IM injection in the vastus lateralis or ventrogluteal site, encourage the patient to gently point toes outwards to relax the muscle. Relaxation skills of the health care provider will help decrease the patient’s anxiety-heightened pain. If possible, divert the patient’s attention away from the injection procedure.<\/td>\n<\/tr>\n
        Pre-medication, if required<\/td>\nTo decrease pain upon insertion, a vapocoolant spray, topical anesthetic, or wrapped ice may be placed on the insertion site for a minute prior to injection. For IM injections, two studies found that applying pressure to the injection site for 10 seconds before the injection reduced pain. This data supports the gate theory of pain control.<\/td>\n<\/tr>\n
        Z-track method for IM injections<\/td>\nSome research shows that the Z-track technique results in reduced pain and complications, and fewer injection lesions. However, other research shows that Z-track injections result in more pain and bleeding at the injection site. (See 7.4 Intramuscular Injections for more on the Z-track method.)<\/td>\n<\/tr>\n
        Administration rate<\/td>\nResearch has found that administrating medications at 10 seconds per ml is an effective rate for IM injections. Increasing the rate to 20 seconds per ml did not show any reduction in pain. Always review drug administration rate as per pharmacy or manufacturer\u2019s recommendations.<\/td>\n<\/tr>\n
        Gentle touch with insertion sites<\/td>\nGently apply a dry sterile gauze to the site after the injection. Rotate injection sites to prevent the development of indurations and abscesses.<\/td>\n<\/tr>\n
        Aspiration with IM injections<\/td>\nReview the latest research regarding the utility of aspirating IM injections. There is lack of strong evidence to support the technique of aspiration with IM injections.<\/td>\n<\/tr>\n

        Preventing Needle-Stick Injuries<\/h2>\n

        Health care providers can be at risk for needle-stick injuries in any health care setting. The most common places for needle-stick injuries to occur are in the operating room and patient rooms. Tasks that place the health care provider at risk include recapping needles and mishandling IV lines. Table 7.4 provides guidelines to prevent needle-stick injuries.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

        Avoid recapping needles.<\/td>\n\n

        Recapping needles has led to the transmission of infection. If possible, always use devices with safety features — i.e., safety shield.<\/p>\n<\/td>\n<\/tr>\n

        Dispose of the needle immediately after injection.<\/td>\n\n

        Immediately dispose of used needles in a sharps disposal container (puncture-proof and leak-proof) to avoid unsafe disposal of a sharp.<\/p>\n<\/td>\n<\/tr>\n

        Reduce or eliminate all hazards related to needles.<\/td>\nAvoid using needles if possible. Use a needle only when performing an SC, ID, or IM injection. Use a needleless system and engineered safety devices for prevention of needle-stick injuries.<\/td>\n<\/tr>\n
        Plan disposal of sharps before injection.<\/td>\nPlan the safe handling and disposal of needles before beginning a procedure that requires a sharp needle.

        Preparing Medications from Ampules and Vials<\/h2>\n

        Specific equipment, such as syringes and needles, is required to prepare and administer parenteral medications. The selection of the syringe and needle is based on the type and location of injection; amount, quality, and type of medication; and the body size of the patient. Many syringes come with needleless systems or needles with safety shields to prevent injuries (Perry et al., 2014).\u00a0Aseptic technique is paramount to the preparation and administration of these medications.<\/p>\n

        Parenteral medications are supplied in sterile vials, ampules, and prefilled syringes. Ampules <\/strong>are glass containers in 1 ml to 10 ml sizes that\u00a0hold a single dose of medication in liquid form. They are made of glass and have a scored neck to indicate where to break the ampule (see Figure 7.2). Medication is withdrawn using a syringe and a filter needle. A blunt fill needle with filter (see Figure 7.3) must be used when withdrawing medication to prevent glass particles from being drawn up into the syringe (see Figure 7.4). Never use a filter needle to inject medication (Perry et al.,\u00a02014).<\/p>\n

        A vial<\/strong>\u00a0is a single- or multi-dose plastic container with a rubber seal top, covered by a metal or plastic cap (see Figure 7.5). A single-use vial must be discarded after one use; a multi-dose vial must be labelled with the date it was opened. Check hospital policy to see how long an open vial may be used. The vial is a closed system, and air must be injected into the vial to permit the removal of the solution (Perry et al., 2014) (see Figure 7.6).<\/p>\n

        A syringe <\/strong>(see Figure 7.7)is a sterile, single-use device that has a Luer lock (see Figure 7.8) or non-Luer lock tip, which influences the name of the syringe. Syringes come in various sizes from 0.5 ml to 60 ml. Syringes may come with or without a sterile needle and will have a safety shield on the needle.<\/p>\n

        Insulin is only given using an insulin syringe (see Figure 7.9). Insulin is ordered in units. It is important to use the correct syringe and needle for the specific injection. Always examine the measurement scale on the syringe to determine that you have the correct syringe (Lynn, 2011).<\/p>\n

        Needles<\/strong> are made of stainless steel, are sterile and disposable, and\u00a0come in various lengths and sizes. The needle is made up of the hub, shaft, and bevel. The bevel is the tip of the needle that is slanted to create a slit into the skin. The hub fits onto the tip of the syringe. All three parts must remain sterile at all times. The length of the needle will vary from 1\/8 in. to 3 in., depending on the injection. The gauge of a needle<\/strong> is the diameter of the needle. Gauges can vary from very small diameter (25 to\u00a029 gauge) to large diameter (18 to\u00a022 gauge). A needle will have its gauge and length marked on the outer packaging; choose the correct gauge and length for the injection ordered (Lynn, 2011) (see Figures 7.10, 7.11, and 7.12).<\/p>\n
