Question 1 of 5
A nurse is preparing to administer enoxaparin subcutaneously to a client using a prefilled syringe. The nurse should plan to use which of the following techniques when administering this medication?
Correct Answer: D
Rationale: Enoxaparin should be injected into abdominal tissue for proper absorption and to minimize bruising. Aspiration, massaging the site, or expelling the air bubble (which ensures full dose delivery) are not recommended techniques for this medication.
Question 2 of 5
A nurse is preparing to administer medications to a client through an enteral feeding tube. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: Flushing with normal saline post-administration ensures full delivery and tube patency. Pinching risks damage, 10° elevation risks aspiration (30°+ is correct), and combining drugs risks interactions.
Question 3 of 5
A nurse is preparing to administer a levothyroxine 50 mcg tablet PO to a client who is receiving an enteral feeding through an NG tube. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: Dissolving levothyroxine in 30 mL of water ensures it's suitable for NG tube administration and prevents clogging. Supine positioning risks aspiration, mixing with formula can reduce efficacy, and 5 mL is insufficient to clear the tube (15-30 mL is standard).
Question 4 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 5 of 5
A nurse is caring for a client who is postoperative following arthroscopy and reports a pain level of 6 on a scale of 0 to 10 after receiving ketorolac 1 hr ago. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: Oxycodone is appropriate for breakthrough pain (6/10) post-ketorolac. Ketorolac isn't dosed every 3 hours, rectal acetaminophen isn't first-line, and labeling as drug-seeking is premature.
