Pharmacology and the Nursing Process 9th Edition Test Bank

Correct Answer: C

Rationale: Step-by-step rationale: 1. Statement C indicates a misunderstanding that medication can be stopped when feeling better, which is incorrect. 2. Hypertension is a chronic condition that often requires lifelong medication. 3. This demonstrates a lack of understanding regarding the necessity of long-term management. 4. Statements A, B, and D show knowledge about hypertension's effects, dietary management, and awareness, respectively. Summary: Statement C is incorrect as it suggests stopping medication, while statements A, B, and D show accurate understanding of hypertension.

Correct Answer: B

Rationale: The correct answer is B: An improvement of the weakness. Edrophonium is a short-acting cholinesterase inhibitor that helps differentiate between myasthenic and cholinergic crises in myasthenia gravis. In cholinergic crisis, there is an overdose of cholinesterase inhibitors leading to excessive acetylcholine at the neuromuscular junction, causing muscle weakness. Administering edrophonium will temporarily improve muscle weakness in cholinergic crisis due to the increased availability of acetylcholine. The other choices are incorrect because: A: No change suggests the client is not in cholinergic crisis. C: Complaints of muscle spasms are more indicative of myasthenic crisis. D: A temporary worsening of the condition is not expected in cholinergic crisis.

Correct Answer: B

Rationale: Rationale: Answer B is correct because a hemoglobin level of 11mg/dl and hematocrit level of 32% in a 78-year-old client are indicative of anemia. Conducting a thorough nutritional assessment is essential to identify potential causes of anemia such as iron deficiency or vitamin deficiencies. This assessment will help determine appropriate interventions to manage the anemia. Summary: A: Incorrect. These levels are indicative of anemia, not normal findings. C: Incorrect. Advising to repeat the test in three months may delay necessary interventions for the anemia. D: Incorrect. While anemia can be related to bone marrow degeneration, a nutritional assessment is needed to identify the specific cause in this case.

Correct Answer: B

Rationale: The correct answer is B because it provides a specific action (offering water) at regular intervals (every 2 hours) to promote hydration, which is a clear and measurable nursing intervention. Choice A is too prescriptive and lacks flexibility. Choice C is reactive and not proactive. Choice D is vague and lacks specific guidance on how to achieve the desired outcome. By offering water consistently, the nurse ensures proactive care and helps meet the client's hydration needs effectively.

Correct Answer: C

Rationale: The correct answer is C: Fluid replacement. In end-stage AIDS with Cryptosporidium infection, the client experiences severe diarrhea leading to dehydration and electrolyte imbalances. Fluid replacement is crucial to prevent hypovolemia and maintain electrolyte balance. Adequate hydration supports renal function, prevents further complications, and aids in the elimination of the infectious agent. Pain management (A) may be needed for discomfort but is not the priority. Antiretroviral therapy (B) is essential for managing HIV but does not directly address the immediate issue of dehydration. High-calorie intake (D) is important for overall nutrition but does not address the urgent need for fluid replacement in this situation.
