Chapter 7. Parenteral Medication Administration

7.5 Intravenous Medications by Direct IV Route

Intravenous (IV) is a method of administering concentrated medications (diluted or undiluted) directly into the vein using a syringe through a needleless port on an existing IV line or a saline lock. The direct IV route usually administers a small volume of fluid/medicine (max 20 ml) that is pushed manually into the patient. Medications given by IV are usually administered intermittently to treat emergent concerns. Medications administered by direct IV route are given very slowly over AT LEAST 1 minute (Perry et al., 2014). Administering a medication intravenously eliminates the process of drug absorption and breakdown by directly depositing it into the blood. This results in the immediate elevation of serum levels and high concentration in vital organs, such as the heart, brain, and kidneys. Both therapeutic and adverse effects can occur quickly with direct intravenous administration (Alberta Health Services, 2009).

In the past, IV medications have been called IV bolus or IV push medications. It is recommended that these terms NOT be used, as they can be mistakenly interpreted as meaning the drugs are to be pushed quickly, in less than a minute (ISMP, 2003). To administer IV medications safely and effectively, all health care agencies have policies in place and the Parenteral Drug Therapy Manual (PDTM) that identifies medications that may be given intravenously. (The PDTM may also be referred to as a parenteral drug monograph [Alberta Health Services, 2009].) Only specific medications may be administered via the direct IV route. There are many advantages and disadvantages to administering medications via the intravenous injection method — see Table 7.8.

Table 7.8 Advantages and Disadvantages of Intravenous Medications

Advantages 

 Disadvantages

Intravenous medications can deliver an immediate, fast-acting therapeutic effect, which is important in emergent situations such as cardiac arrest or narcotic overdose. They are useful to manage pain and nausea by quickly achieving therapeutic levels, and they are more consistently and completely absorbed compared with medications given by other routes of injection. Once an intravenous medication is delivered, it cannot be retrieved. When giving IV medications, there is very little opportunity to stop an injection if an adverse reaction or error occurs. IV medications, if given too quickly or incorrectly, can cause significant harm or death.
Doses of short-acting medication can be titrated according to patient responses to drug therapy. Medication can be prepared quickly and given over a shorter period of time compared to the IV piggyback route. Any toxic or adverse reaction will occur immediately and may be exacerbated by a rapidly injected medication.
Minimal dilution is required for some medications, which is desirable for patient’s own fluid restrictions. Extravasation of certain medications into surrounding tissues can cause sloughing, nerve damage, and scarring.
There is minimal or no discomfort for the patient in comparison to SC and IM injections. Not all medications can be given via the direct IV route.
They provide an alternative to the oral route for drugs that may not be absorbed by the GI tract, and they are ideal for patients with GI dysfunction or malabsorption, and patients who are NPO (nothing by mouth) or unconscious. There is a high risk for infusion reactions, mild to severe, because most IV medications peak rapidly (i.e., they have a quick onset of effect). A hypersensitivity reaction can occur immediately or be delayed, and requires supportive measures.
IV direct route provides a more accurate dose of medication because none is left in the intravenous tubing. Route for administering medications may damage surrounding tissues. There is an increased risk of phlebitis with highly concentrated medication, especially with small peripheral veins or a short venous access device.
Data source: Albert Health Services, 2009; Lynn, 2011; Perry et al., 2014

Intravenous medications are always prepared using the SEVEN rights x 3 as per agency policy. Because of the high risk associated with direct intravenous medications, additional guidelines are required. A PDTM or drug monograph provides additional information, which includes the generic name, brand name, classification of the drug, and chart defining which parenteral route may be utilized. Some medications may only be given via a piggyback method or large-volume IV solutions; some medications may be given diluted over 1 or 2 minutes. In addition, information regarding indications, contraindications, dosage (age dependent), administration/dilution guidelines, adverse effects, clinical indications (e.g., specialized monitoring required, must be on an IV pump), compatibility, and incompatibility in relation to reconstitution and primary IV solution is specified (Alberta Health Services, 2009).

The Institute for Safe Medication Practices (ISMP) (2014) has created a list of high-alert medications that bear the heightened risk of significant harm when they are used in error. Special safeguards for these medications can be found in the PDTM. It is vital to understand which medications are considered high risk prior to administration. A link to the list of high-risk medications can be found under Suggested Online Resources at the end of this chapter. Review the steps shown in Table 7.9 to prepare a medication by direct IV route. The PDTM must be consulted every time an IV medication is given, as memory-based errors are common (World Health Organization, 2012).

Table 7.9 Preparation Questions for Intravenous Medications
Safety Considerations:
  • Be diligent and follow all policies related to medication calculations, preparation, and thorough assessment of patient status before and after an injection. Medication errors are the most common preventable errors in health care.
  • Use a blunt filter needle or blunt needle when preparing injections. Never use a needle when injecting IV medication. Always use a needleless system.
  • After preparing the medication, always label the medication syringe with the patient name, date, time, medication, and dose. Never leave the syringe unattended.
  • Always administer the post-saline lock flush at the SAME RATE as the IV medication.
  • Always assess the patient’s symptoms and need for IV medication prior to administration.
  • Always assess the patient’s understanding of the medication.

Principle

 Additional Information

Verify qualifications for administration.

Are you qualified to give this medication? What supervision is required? What resources must you consult?

Review route of administration and IV site.

Can this medication be given by the IV route? Is the route of administration (needle insertion site) free from redness, swelling, and discomfort?

Review preparation and how to administer the medication. How is this medication given by the IV route (diluted or undiluted)? Describe the safest way to prepare the medication. Consider the selection of medication. Always use less-concentrated solutions whenever possible. Does the medication require dilution? If diluting the medication, ALWAYS discard (that is, waste) the unused portion before going to the bedside.

  • Preparation and supplies: is a pre-flush required?
  • Patient identification: any allergies?
  • Administration rate: what is the correct rate of administration (over 1 minute, 5 minutes)?
Identify when medication starts to work. What is the onset, peak, and duration of the medication?
Assess dose and range (e.g., 5 to 10 mg). Is the ordered dose safe? When did the patient last receive this medication? What was the effect of the medication on the patient?
Understand the therapeutic effect. What is the expected therapeutic effect of the medication? What preassessment determines if the medication is correct for the patient?
Know adverse effects. What are the potential adverse effects of the medications? How would you manage these adverse effects? Is there an antidote?
Know potential incompatibilities. Are there any potential incompatibilities with existing IV solutions? How would you manage these issues? Is a secondary medication currently running? Are there additives to the IV solution?
Know how to complete the procedure. How do you complete this procedure? Is a post-saline lock flush required?
Document procedure. How and where do you chart this medication: pain assessment sheet, MAR, etc.?
Data source: BCIT, 2015; Berman & Snyder, 2016; Clayton et al., 2010; WHO, 2012

Before giving an intravenous medication, always assess the IV needle insertion site for signs of infiltration or phlebitis. Start a new IV site if current site is red, swollen, or painful when flushing. Intravenous medications by direct IV route can be given three ways:

  • Through a saline lock (short venous access device)
  • Through an existing IV line with compatible IV solution
  • Through an existing IV with an incompatible IV solution

Checklist 60 reviews the steps to administer an IV medication through a saline lock. Review the preparation questions for intravenous medication in Table 7.9 prior to administering medication.

Checklist 60: Administering an IV Medication via a Saline Lock
Disclaimer: Always review and follow your hospital policy regarding this specific skill.
Safety Considerations: 
  • Review the advantages and disadvantages of IV medications.
  • Be able to answer the preparation questions for intravenous medication in Table 7.9 before administering the medication.
  • If the medication has been diluted and there is wastage, always discard unused diluted portion of the prepared IV medication before going to the bedside.
  • Always label the IV syringe with the patient name, date, time, medication, concentration of the dose, dose, and your initials. Once the medication is prepared, never leave it unattended.
  • NEVER administer an IV medication through an IV line that is infusing blood, blood products, heparin IV, insulin IV, cytotoxic medications, or parenteral nutrition solutions.
  • Central venous catheters (central lines, PICC lines) may require special pre- and post-flushing procedures and specialized training.
  • You will need a watch with a second hand to time the rate of administration.

Steps

 Additional Information

1. Prepare one medication for one patient at the correct time as per agency policy. Review the physician’s order, PDTM, and MAR for the correct order and guidelines. Math calculations may be required to determine the correct dose to prepare the medication. Always apply the SEVEN rights x 3 of medication administration.

Review the agency policy if a medication is a stat, given for the first time, a loading dose, or a one-time dose.

Some agencies require that high-alert medications be double-checked by a second health care provider. Always follow agency policies. For a list of high-alert medications, see Suggested Online Resources.

After preparing the medication, always label the medication syringe with the patient name, date, time, medication, and concentration of the dose (e.g., morphine 2 mg/ml), dose, and your initials. Never leave the medication syringe unattended.

2. Create privacy if possible. This provides comfort to patient.
3. Confirm patient ID using two patient identifiers (e.g., name and date of birth) AND compare the MAR printout with the patient’s wristband to confirm patient ID. This ensures you have the correct patient and complies with agency standard for patient identification.

Compare MAR with patient name band
Compare MAR with patient wristband
4. Check allergy band for any allergies, and ask patient about type and severity of reaction. This ensures allergy status is correct on the MAR and on patient allergy band.
5. Discuss purpose, action, and possible side effects of the medication. Provide patient an opportunity to ask questions. Encourage patient to report discomfort at the IV site (pain, swelling, or burning). Keeping patient informed of what is being administered helps decrease anxiety.
6. Perform hand hygiene. Hand hygiene prevents the transmission of microorganisms.

11. Remove used medication syringe. Remove air from prefilled NS syringe and attach to the Max Plus device.

Flush (3 to 5 ml) at the SAME rate as the medication bolus, according to guidelines found in the PDTM or per IV bolus medication policy. (See Rationale for Flushing with NS after Administering an IV Medication.)

 

Always check hospital policy on the amount of flush and type of solution when using a saline lock for an IV bolus medication.

Flushing the IV line at the same rate as medication delivery ensures that any medication remaining within the IV line is delivered at the correct rate, and avoids giving the patient an accidental bolus of the medication.

Assess IV site prior to use
When flushing is complete, detach syringe from positive pressure device and then apply clamp on extension tubing

If a patient has a central venous catheter, access and flush as per agency policy.

12. Dispose of all syringes/filter needles into appropriate puncture-proof containers. This prevents accidental needle-stick injuries.
13. Remove gloves and perform hand hygiene. This reduces transmission of microorganisms.

Special Considerations:
  • Top contributing factors to medication errors include calculation errors, drug preparation errors, human error, and transcription inaccuracy.
  • The elderly and the young may be more sensitive to adverse effects.
  • With certain medications, creatinine clearance must be assessed prior to administering. Patients with cirrhosis may require a reduction in dosages.
  • When a medication dose is given a range (e.g., morphine 2 mg IV q 2-4 hours p.r.n., or as needed), always start with the lowest dose and titrate up. Always assess when the last dose was given and its effectiveness.

Rationale for Flushing with NS after Administering an IV Medication

Flushing a Saline Lock after Administering an IV Medication

Flushing after IV medication administration with compatible IV solution is recommended as per the guidelines in Checklists 60, Checklist 61, and Checklist 62 to ensure that medication left in the extension tubing is administered at the appropriate rate. IV medication must be cleared by flushing at the same rate of administration to avoid the risks related to IV push medications. Because 1 ml of medication is left in the extension tubing, due care in flushing is required for the first ml that clears the extension tubing. The remaining saline flush serves to maintain patency of the line.

Here are some examples of clearing IV medication from extension tubing.

  1. If morphine (1 mg) is diluted in 1 ml NS and administered over one minute, the subsequent saline flush will be given in this manner: the first 1 ml of a 5 ml saline flush syringe will be delivered over one minute, and the remaining 4 ml will be given slowly at the level of patient comfort.
  2. If Lasix (40 mg) is given in a 4 ml volume and administered over two minutes, the subsequent saline flush will be given in this manner: the first 1 ml of a 5 ml saline flush syringe will be delivered over 30 seconds, and the remaining 4 ml will be given slowly at the level of patient comfort.
Flushing the Primary IV Line after Administering an IV Medication through an IV Port

When flushing an IV line after administering an IV medication, the following applies:

  • The volume in the IV tubing from the Max Plus saline lock to the first port is also 1 ml. Take this additional volume into account when flushing after a medication is given via this port.
  • It is NOT recommended to speed up the IV solution, because medication in the line would be administered too rapidly and is contrary to the manufacturer’s safety recommendation and the PDTM.
  • Sudden boluses of some medications may cause mild to severe adverse effects, such as hypotension and toxicity (Clayton et al., 2010).

Checklist 61 lists the steps to administering an IV medication through an existing IV line with compatible IV solution. Review the preparation questions for intravenous medication in Table 7.9 prior to the medication administration.
