Chapter 37 : Administering Intradermal, Subcutaneous, and Intramuscular Injections Questions
Question 1 of 5
Which of the following steps should the nurse perform when combining two types of insulin and administering them?
Correct Answer: B,D
Rationale: When mixing insulins, draw up clear (regular) insulin before cloudy (intermediate-acting) to avoid contamination. A 45- or 90-degree angle is used for subcutaneous injections. Lantus should not be mixed with other insulins.
Question 2 of 5
A nurse needs to administer medication from an ampule. What of the following steps should the nurse take when drawing up this medication?
Correct Answer: A,B,C,E
Rationale: Proper ampule use involves breaking the neck with gauze, holding it away from the body, tilting to access liquid, and using a filter needle to prevent glass particles. Tapping is acceptable to move liquid.
Question 3 of 5
What gauge and length of needle would you select to administer an IM injection of a nonviscous medication in the ventrogluteal site of a 40-year-old male construction worker who is in good health and weighs 185 pounds?
Correct Answer: C
Rationale: For a healthy adult male, a 22-gauge, 1½-inch needle is appropriate for an IM injection in the ventrogluteal site to ensure adequate muscle penetration for a nonviscous medication.
Question 4 of 5
You are about to administer a standard P.P.D. to a 31-year-old male. Which of the following needles and syringes would be appropriate to use?
Correct Answer: A
Rationale: A tuberculin syringe with a 27-gauge, ??-inch needle is appropriate for a PPD test, which is an intradermal injection requiring a small volume and fine needle.
Question 5 of 5
In which of the following injections should you avoid aspirating before injecting the medication?
Correct Answer: B,C,E
Rationale: Aspiration is not required for intradermal (e.g., TB test) or subcutaneous injections (e.g., insulin, anticoagulants) as these routes are not typically associated with blood vessels.
