Pharmacology and the Nursing Process 9th Edition Test Bank

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.

Correct Answer: B

Rationale: The correct answer is B: IV is the route of choice for rapid administration. IV route allows for quick onset of action, crucial in acutely fluid-overloaded patients needing immediate diuresis. Option A is incorrect as furosemide can be given orally too. Option C is less relevant in this urgent situation where speed is key. Option D is also incorrect as the side effects are not determined by route of administration.

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: C

Rationale: Step-by-step rationale for why choice C is correct: 1. The lab value of K at 3.2 mEq/L indicates hypokalemia. 2. Digitalis can worsen hypokalemia and lead to toxicity. 3. Avoiding foods rich in potassium will prevent further lowering of potassium levels. 4. This intervention helps prevent potential digitalis toxicity in the client. Summary of why the other choices are incorrect: A. Stopping digitalis therapy abruptly can lead to rebound effects and worsen the condition. B. Trousseau's and Chvostek's signs are not relevant to the client's current lab values. D. While observing for digitalis toxicity is important, addressing the low potassium level is a more immediate concern in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Fluid intake of less than 2,500mL. In diabetes insipidus, the body cannot properly regulate fluid balance, leading to excessive thirst and urination. Successful treatment aims to manage these symptoms by reducing fluid intake to prevent dehydration. Therefore, a decrease in fluid intake indicates successful treatment. Explanation for incorrect choices: B: Blood pressure of 90/50mmHg - Blood pressure is not directly related to the treatment of diabetes insipidus. C: Pulse rate of 126 beats/min - Pulse rate is not a specific indicator of successful treatment for diabetes insipidus. D: Urine output of more than 200mL/hour - In diabetes insipidus, excessive urine output is a symptom of the condition, so an increase in urine output does not indicate successful treatment.
