Question 1 of 5
A nurse is collecting data from a client who received diphenhydramine for insomnia. Which of the following findings should the nurse identify as an idiosyncratic reaction?
Correct Answer: C
Rationale: Agitation is an idiosyncratic (unexpected) reaction to diphenhydramine, which typically sedates. Dry mouth, nausea, and dizziness are common side effects.
Question 2 of 5
A nurse is collecting data from a client who has hypertension. The nurse should recognize that which of the following over-the-counter medications is contraindicated for this client?
Correct Answer: B
Rationale: Pseudoephedrine, a decongestant, can raise blood pressure, making it contraindicated in hypertension. Docusate, omeprazole, and guaifenesin don't significantly affect BP.
Question 3 of 5
A nurse is obtaining a medication history from a client who has systemic lupus erythematosus (SLE) and reports taking several herbal supplements daily. The nurse should identify that SLE is a contraindication for taking which of the following herbal supplements?
Correct Answer: C
Rationale: Echinacea boosts the immune system, which can worsen autoimmune conditions like SLE. Flaxseed, glucosamine, and ginger are not contraindicated and may even offer anti-inflammatory benefits.
Question 4 of 5
A nurse is preparing to administer an antibiotic via intermittent IV bolus for a client who has a continuous IV infusion. Which of the following steps should the nurse take first?
Correct Answer: C
Rationale: Checking the IV site for infiltration ensures proper placement before administration, a critical first step. Hanging, wiping, and connecting follow this safety check.
Question 5 of 5
A nurse is preparing to administer an IM injection to a client who has gonorrhea. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The Z-track technique prevents leakage into subcutaneous tissue for IM injections like those for gonorrhea. Umbilicus distance applies to subcutaneous injections, aspiration is standard, and a 27-gauge needle is too small.
