1. A client is receiving heparin therapy. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?

Correct answer: B

Rationale: The corrected answer is B: aPTT. The activated partial thromboplastin time (aPTT) is the laboratory value used to monitor the effectiveness of heparin therapy. The aPTT should be maintained at 1.5 to 2 times the normal level to ensure therapeutic anticoagulation. Monitoring aPTT helps healthcare providers adjust heparin doses to achieve the desired anticoagulant effects and prevent complications such as bleeding or clotting. Choice A, PT (prothrombin time), is used to monitor warfarin therapy, not heparin. Choice C, INR (international normalized ratio), is also used to monitor warfarin therapy. Choice D, platelet count, is important for assessing the risk of bleeding, but it does not directly monitor the effectiveness of heparin therapy.

2. A healthcare provider is reviewing the health care record of a client who reports urinary incontinence and asks about a prescription for Oxybutynin. The provider should recognize that Oxybutynin is contraindicated in the presence of which of the following conditions?

Correct answer: D

Rationale: Oxybutynin is an anticholinergic medication that can increase intraocular pressure. It is contraindicated in clients with glaucoma, as it can worsen the condition. Glaucoma is a condition characterized by increased intraocular pressure, and using Oxybutynin can further elevate this pressure, potentially leading to serious complications such as vision impairment or damage to the optic nerve. Choices A, B, and C are incorrect as bursitis, sinusitis, and depression are not contraindications for Oxybutynin use. Therefore, the correct answer is D, Glaucoma.

3. A client has a new prescription for Hydrochlorothiazide. Which of the following adverse effects should the nurse monitor?

Correct answer: A

Rationale: Corrected Rationale: Hydrochlorothiazide is a diuretic known to cause electrolyte imbalances, particularly hyponatremia (low sodium levels). The nurse should closely monitor the client for signs of hyponatremia by assessing their electrolyte levels. Choice B, Hyperkalemia, is incorrect as hydrochlorothiazide is more likely to cause hypokalemia (low potassium levels) rather than hyperkalemia. Choice C, Hypercalcemia, is incorrect because hydrochlorothiazide is not known to cause increased calcium levels. Choice D, Hypoglycemia, is also incorrect as it is not a common adverse effect of hydrochlorothiazide.

4. A healthcare provider is preparing to administer an IV bolus of Morphine to a client for pain management. Which of the following assessments is the healthcare provider's priority?

Correct answer: A

Rationale: The priority assessment for a healthcare provider preparing to administer an IV bolus of Morphine is the client's respiratory rate. Morphine can cause respiratory depression as a significant adverse effect, so monitoring the respiratory rate is crucial to detect any signs of respiratory compromise and intervene promptly. Assessing the respiratory rate takes precedence over other assessments because respiratory depression can lead to serious complications. While pain level, blood pressure, and level of consciousness are important assessments, they are not the priority when administering Morphine, as the risk of respiratory depression is a more immediate concern.

5. 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?

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.
