- What is the most critical aspect of preparing for parenteral medication administration?
a) Choosing the right size needle
b) Ensuring the medication is at room temperature
c) Using aseptic technique to prevent infection
d) Confirming the expiration date
Answer: c) Using aseptic technique to prevent infection
Rationale: Aseptic technique is vital to reduce the risk of infection during parenteral administration.
- Which site is commonly used for intramuscular (IM) injections?
a) Dorsal aspect of the hand
b) Ventrogluteal muscle
c) Subcutaneous tissue of the abdomen
d) Inner forearm
Answer: b) Ventrogluteal muscle
Rationale: The ventrogluteal site is preferred for IM injections due to its deep muscle location and reduced risk of nerve injury.
- What is the appropriate technique for drawing up medication from a vial?
a) Use a single needle to draw up the medication and inject
b) Inject air into the vial before drawing up medication
c) Draw medication directly from the vial without using a syringe
d) Use a blunt needle for drawing up and a sharp needle for injection
Answer: b) Inject air into the vial before drawing up medication
Rationale: Injecting air helps equalize pressure, making it easier to draw the medication.
- What is the risk associated with administering parenteral medications?
a) Lower effectiveness compared to oral medications
b) Increased risk of drug interactions
c) Potential for needle-stick injuries and infection
d) Longer duration of action
Answer: c) Potential for needle-stick injuries and infection
Rationale: Parenteral administration carries a higher risk for injuries and infections if aseptic technique is not followed.
- How should a nurse respond if a patient shows signs of an allergic reaction after a parenteral medication is administered?
a) Continue monitoring the patient
b) Administer another dose of the medication
c) Stop the medication and notify the provider immediately
d) Document the reaction only if it is severe
Answer: c) Stop the medication and notify the provider immediately
Rationale: Promptly stopping the medication and informing the provider is crucial in managing allergic reactions.
- Which parenteral route is often used for vaccinations?
a) Intravenous
b) Subcutaneous
c) Intramuscular
d) Intraosseous
Answer: c) Intramuscular
Rationale: Many vaccines are administered intramuscularly for optimal absorption and immune response.
- What is the best practice for disposing of used needles and syringes?
a) Throw them in the regular trash
b) Recap the needle before disposal
c) Place them in a designated sharps container
d) Flush them down the toilet
Answer: c) Place them in a designated sharps container
Rationale: Used needles and syringes must be disposed of in sharps containers to prevent injury and infection.
- Which gauge needle is typically used for drawing up thick medications, such as certain antibiotics?
a) 25-gauge
b) 18-gauge
c) 22-gauge
d) 30-gauge
Answer: b) 18-gauge
Rationale: An 18-gauge needle is larger and suitable for drawing up thicker medications.
- In which scenario would a nurse administer a medication via the subcutaneous route?
a) For rapid fluid resuscitation
b) For a bolus of medication
c) For slow absorption of medication
d) For immediate pain relief
Answer: c) For slow absorption of medication
Rationale: Subcutaneous injections provide a slower and more sustained absorption than intramuscular or intravenous routes.
- What is a critical step in ensuring aseptic technique during parenteral medication preparation?
a) Wearing gloves
b) Using an alcohol swab to clean the vial top
c) Pre-filling syringes
d) Storing medication at room temperature
Answer: b) Using an alcohol swab to clean the vial top
Rationale: Cleaning the vial top with an alcohol swab reduces the risk of contamination.
- When preparing to give an intradermal injection, what angle should the needle be inserted?
a) 15 degrees
b) 30 degrees
c) 45 degrees
d) 90 degrees
Answer: a) 15 degrees
Rationale: Intradermal injections are given at a 15-degree angle to ensure the medication is delivered just under the skin.
- Which of the following is NOT a parenteral route of administration?
a) Intravenous
b) Subcutaneous
c) Sublingual
d) Intramuscular
Answer: c) Sublingual
Rationale: Sublingual is an oral route, not a parenteral route.
- What action should a nurse take if a medication’s label is unclear before administration?
a) Proceed with the administration
b) Consult the pharmacy or provider for clarification
c) Guess based on the patient’s history
d) Administer half the dose
Answer: b) Consult the pharmacy or provider for clarification
Rationale: Unclear medication labels must be clarified to prevent errors.
- What is the typical volume limit for intradermal injections?
a) 0.5 mL
b) 1 mL
c) 2 mL
d) 0.1 mL
Answer: d) 0.1 mL
Rationale: Intradermal injections typically use volumes of 0.1 mL or less to avoid tissue damage.
- Which factor can affect the absorption rate of a parenteral medication?
a) The patient’s age
b) The medication’s form
c) Injection site blood flow
d) All of the above
Answer: d) All of the above
Rationale: Several factors, including age, medication form, and blood flow, influence absorption rates.
- Which equipment is necessary for administering parenteral medications?
a) Oral syringe
b) Glass ampule
c) Band-aids only
d) Sterile gloves
Answer: d) Sterile gloves
Rationale: Wearing sterile gloves is essential to maintain aseptic technique during parenteral medication administration.
- Which of the following medications is commonly administered via the intranasal route?
a) Insulin
b) Vaccines
c) Naloxone
d) Heparin
Answer: c) Naloxone
Rationale: Naloxone can be effectively administered intranasally for opioid overdose reversal.
- Why is it important to rotate injection sites for parenteral medications?
a) To enhance patient comfort
b) To prevent tissue damage and scarring
c) To reduce the risk of infection
d) All of the above
Answer: d) All of the above
Rationale: Rotating sites improves comfort, minimizes tissue damage, and reduces infection risks.
- Which route of administration allows for the fastest onset of action?
a) Intramuscular
b) Subcutaneous
c) Intravenous
d) Oral
Answer: c) Intravenous
Rationale: Intravenous administration delivers medication directly into the bloodstream for immediate effect.
- What is the maximum volume typically administered via the intramuscular (IM) route in adults?
a) 0.5 mL
b) 1 mL
c) 2 mL
d) 5 mL
Answer: c) 2 mL

- Which site is preferred for subcutaneous (SC) injections?
a) Deltoid muscle
b) Ventrogluteal site
c) Abdomen
d) Dorsal gluteal site

- Which route of administration requires the medication to be injected into the dermis?
a) Subcutaneous
b) Intramuscular
c) Intradermal
