A patient with chronic kidney disease (CKD) is prescribed calcium acetate. What is the primary purpose of this medication?
- A. Treat hyperkalemia
- B. Reduce phosphate levels
- C. Lower blood pressure
- D. Increase hemoglobin levels
Correct Answer: B
Rationale: The primary purpose of prescribing calcium acetate for a patient with CKD is to reduce phosphate levels. Calcium acetate acts as a phosphate binder, preventing the absorption of dietary phosphate in the intestines. Elevated phosphate levels in CKD can lead to complications such as mineral and bone disorders. Treating hyperkalemia (A) involves other medications like potassium binders, not calcium acetate. Lowering blood pressure (C) typically involves antihypertensive drugs. Increasing hemoglobin levels (D) is usually managed with erythropoiesis-stimulating agents in CKD patients. Therefore, option B is the correct answer for the primary purpose of prescribing calcium acetate in CKD patients.

Following a CVA, the nurse assesses that a client has developed dysphagia, hypoactive bowel sounds, and a firm, distended abdomen. Which prescription for the client should the nurse question?
- A. Continuous tube feeding at 65 ml/hr via gastrostomy.
- B. Total parenteral nutrition to be infused at 125 ml/hour.
- C. Nasogastric tube connected to low intermittent suction.
- D. Metoclopramide (Reglan) intermittent piggyback.
Correct Answer: A
Rationale: The correct answer is A: Continuous tube feeding at 65 ml/hr via gastrostomy. After a CVA, dysphagia, hypoactive bowel sounds, and a firm, distended abdomen indicate a risk for aspiration and bowel obstruction. Continuous tube feeding may worsen these issues. Option B provides nutrition intravenously, bypassing the gastrointestinal tract. Option C helps decompress the stomach. Option D is a medication to help with GI motility. Therefore, the nurse should question option A due to the risk of complications post-CVA.
A patient with diabetes insipidus is prescribed desmopressin. What is the primary purpose of this medication?
- A. Increase urine output
- B. Reduce blood sugar levels
- C. Decrease urine output
- D. Lower blood pressure
Correct Answer: C
Rationale: Desmopressin is a synthetic form of vasopressin used to replace the hormone in diabetes insipidus. The primary purpose is to decrease urine output by increasing water reabsorption in the kidneys, thereby reducing excessive urination and preventing dehydration. Choice A is incorrect as desmopressin actually decreases urine output. Choice B is incorrect as desmopressin does not directly affect blood sugar levels. Choice D is incorrect as desmopressin does not primarily lower blood pressure.
A patient with chronic pain is prescribed gabapentin. What is the primary purpose of this medication?
- A. Relieve neuropathic pain
- B. Reduce inflammation
- C. Enhance opioid analgesia
- D. Suppress cough
Correct Answer: A
Rationale: The correct answer is A: Relieve neuropathic pain. Gabapentin is commonly used to treat neuropathic pain by stabilizing electrical activity in the brain and nervous system. It is effective in conditions such as diabetic neuropathy and postherpetic neuralgia. Choice B is incorrect because gabapentin does not have anti-inflammatory properties. Choice C is incorrect as gabapentin does not enhance opioid analgesia, but it can be used in conjunction with opioids for pain management. Choice D is incorrect as gabapentin is not indicated for cough suppression.
A patient with chronic pain is prescribed a fentanyl patch. What is the most important instruction for the nurse to provide?
- A. Apply the patch to a different site each time.
- B. Change the patch every 72 hours.
- C. Avoid using additional heating pads over the patch.
- D. Remove the patch before showering.
Correct Answer: B
Rationale: The correct answer is B: Change the patch every 72 hours. Fentanyl patches are typically designed to be worn for 72 hours before being replaced to maintain consistent pain relief. Changing the patch on time helps prevent withdrawal symptoms and ensures the effectiveness of the medication.
A: Applying the patch to a different site each time is important to prevent skin irritation but is not the most crucial instruction.
C: Avoiding heating pads over the patch is important to prevent overheating and excessive absorption of the medication, but changing the patch timely is more critical.
D: Removing the patch before showering is not necessary as fentanyl patches are designed to be water-resistant.
A client with heart failure is receiving intravenous furosemide (Lasix). Which assessment finding indicates that the medication is having the desired effect?
- A. Decreased peripheral edema.
- B. Elevated blood pressure.
- C. Increased heart rate.
- D. Decreased urine output.
Correct Answer: A
Rationale: The correct answer is A: Decreased peripheral edema. Furosemide is a diuretic that helps to remove excess fluid from the body, which can reduce peripheral edema in patients with heart failure. This indicates that the medication is effectively reducing fluid overload in the body. Elevated blood pressure (choice B) would not be an expected outcome of furosemide use. Increased heart rate (choice C) is not a direct effect of furosemide and can indicate worsening heart failure. Decreased urine output (choice D) would be an adverse effect of furosemide and would indicate the medication is not working as intended.
