1. A client is receiving warfarin for atrial fibrillation. Which of the following laboratory tests should the nurse expect to be ordered to monitor the effect of warfarin?
- A. Platelet count
- B. International normalized ratio (INR)
- C. Prothrombin time (PT)
- D. Partial thromboplastin time (PTT)
Correct answer: B
Rationale: The correct answer is B: International normalized ratio (INR). When a client is on warfarin therapy, the INR is monitored regularly to assess the anticoagulant effects of the medication. A therapeutic INR range for most indications is between 2.0 to 3.0. Choices A, C, and D are not typically used to monitor the effect of warfarin. Platelet count assesses the number of platelets in the blood, PT measures the clotting time of plasma, and PTT evaluates the intrinsic pathway of coagulation.
2. A nurse is assessing a client who is receiving morphine for pain management. Which of the following findings should the nurse report to the provider?
- A. Heart rate of 62/min
- B. Blood pressure of 118/78 mm Hg
- C. Respiratory rate of 10/min
- D. Pain rating of 4 on a scale of 0 to 10
Correct answer: C
Rationale: The correct answer is C. A respiratory rate of 10/min indicates respiratory depression, a serious adverse effect of morphine that should be reported immediately. Options A, B, and D are within normal limits and are not indicative of a potentially life-threatening complication associated with morphine therapy.
3. A client in the post-anesthesia recovery unit received a nondepolarizing neuromuscular blocking agent and has muscle weakness. The nurse should anticipate a prescription for which of the following medications?
- A. Neostigmine
- B. Naloxone
- C. Dantrolene
- D. Vecuronium
Correct answer: A
Rationale: Neostigmine is a cholinesterase inhibitor commonly used to reverse the effects of nondepolarizing neuromuscular blockers, such as the one the client received. It works by inhibiting the breakdown of acetylcholine, thereby enhancing neuromuscular transmission and reversing muscle weakness caused by the neuromuscular blocking agent.
4. Which physiologic role does vitamin C play in the body?
- A. Transcribing DNA to RNA
- B. Absorption and regulation of calcium
- C. Protects integrity of cellular membranes
- D. Catalyst for synthesis of blood-clotting factors
Correct answer: C
Rationale: Vitamin C plays a crucial role in protecting the integrity of cellular membranes. It is essential for collagen synthesis, which is important for wound healing and maintaining skin, blood vessels, and other tissues. Choice A is incorrect as the transcription of DNA to RNA is facilitated by vitamin A. Choice B is incorrect as calcium absorption and regulation are functions of vitamin D. Choice D is incorrect as vitamin K serves as a catalyst for the synthesis of blood-clotting factors, not vitamin C.
5. A client has a new prescription for Maraviroc to treat HIV infection. The healthcare provider should monitor the client for which of the following adverse reactions?
- A. Liver failure
- B. Kidney failure
- C. Pancreatitis
- D. Severe allergic reactions
Correct answer: D
Rationale: The correct answer is D: Severe allergic reactions. Maraviroc, used to treat HIV infection, can lead to severe allergic reactions, including hepatotoxicity. While liver failure is a potential adverse effect, it is often preceded by hepatotoxicity manifestations like jaundice or right upper quadrant pain. Kidney failure and pancreatitis are not typically associated with Maraviroc use. Therefore, monitoring for signs of severe allergic reactions and hepatotoxicity is crucial for early detection and intervention.
