Nursing Elites

1. A client with chronic renal failure is scheduled to receive epoetin alfa (Epogen). Which laboratory result should the nurse review before administering the medication?

• A. Blood urea nitrogen (BUN)
• B. Creatinine clearance
• C. Hemoglobin level
• D. Serum potassium

Correct answer: C

Rationale: The correct answer is to review the hemoglobin level before administering epoetin alfa (Epogen) to assess its effectiveness in stimulating red blood cell production. Hemoglobin level is a crucial indicator to monitor in clients with chronic renal failure receiving this medication. Choice A (Blood urea nitrogen) and Choice B (Creatinine clearance) are commonly monitored in renal failure but are not specifically relevant to assessing the effectiveness of epoetin alfa. Choice D (Serum potassium) is important to monitor due to potential imbalances in renal failure, but it is not directly related to evaluating the effectiveness of epoetin alfa.

2. A patient with asthma is prescribed a corticosteroid inhaler. What is the most important instruction to give to the patient?

• A. Use the inhaler only during asthma attacks.
• B. Rinse the mouth after using the inhaler.
• C. Take a double dose if symptoms worsen.
• D. Avoid using a spacer with the inhaler.

Correct answer: B

Rationale: The most important instruction to give to a patient using a corticosteroid inhaler is to rinse the mouth after each use. This is crucial to prevent the development of oral thrush, a common side effect of corticosteroid inhalers. Failure to rinse the mouth can lead to the overgrowth of yeast in the mouth, causing oral thrush, which can be uncomfortable and require additional treatment. Therefore, reminding patients to rinse their mouth after using the inhaler is essential in preventing this potential complication. Choices A, C, and D are incorrect. Using the inhaler only during asthma attacks may lead to uncontrolled asthma symptoms. Taking a double dose without healthcare provider instruction can result in overdose or side effects. Avoiding a spacer with the inhaler can reduce the effectiveness of delivering the medication to the lungs.

3. What action should the healthcare provider take to reduce the risk of vesicant extravasation in a client receiving intravenous chemotherapy?

• A. Administer an antiemetic before starting the chemotherapy.
• B. Instruct the client to drink plenty of fluids during the treatment.
• C. Keep the head of the bed elevated until the treatment is completed.
• D. Monitor the client's intravenous site hourly during the treatment.

Correct answer: D

Rationale: Monitoring the intravenous site hourly is essential to identify early signs of extravasation, such as swelling or pain, which can help prevent tissue damage. Prompt detection allows for immediate intervention, minimizing the risk of serious complications associated with vesicant extravasation.

4. The client with a history of heart failure is taking furosemide (Lasix). Which laboratory result should the nurse monitor closely?

• A. Serum sodium.
• B. Serum potassium.
• C. Serum calcium.
• D. Serum magnesium.

Correct answer: B

Rationale: Furosemide (Lasix) is a loop diuretic that can lead to potassium loss, causing hypokalemia. Monitoring serum potassium levels is crucial to prevent complications such as cardiac dysrhythmias associated with low potassium levels.

5. An otherwise healthy 45-year-old man presents with severe hematochezia and moderate abdominal cramping since this morning. A barium enema one year ago was normal. On examination, his blood pressure is 120/78 and pulse is 100 while lying; when standing, the blood pressure is 110/76 and pulse is 136. His hematocrit is 34. What is the most likely cause of bleeding?

• A. Diverticular bleed
• B. Duodenal ulcer
• C. Inflammatory bowel disease
• D. Vascular ectasia (watermelon stomach)

Correct answer: B

Rationale: The patient's presentation with hematochezia, moderate abdominal cramping, and hemodynamic changes (increased pulse on standing) suggests an upper gastrointestinal bleed. The drop in blood pressure and rise in pulse rate when standing indicate orthostatic hypotension, which is a sign of significant blood loss. The absence of melena does not rule out an upper GI bleed. Ulcers in the duodenal bulb can erode into the gastroduodenal artery, leading to brisk blood loss. A normal barium enema one year ago makes diverticular bleeding less likely. Inflammatory bowel disease usually does not cause severe acute GI bleeding unless there is ulceration into a vessel. Vascular ectasia, like watermelon stomach, typically presents with chronic blood loss and iron deficiency anemia, more common in older women. The absence of vomiting and the presence of hematochezia make Mallory-Weiss tear less likely in this case.
