Nursing Elites

1. 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.

2. A patient with hypertension is prescribed lisinopril. What side effect should the nurse monitor for?

• A. Hyperkalemia
• B. Hypoglycemia
• C. Bradycardia
• D. Constipation

Correct answer: A

Rationale: When a patient is prescribed lisinopril, an ACE inhibitor, the nurse should monitor for hyperkalemia. Lisinopril can cause hyperkalemia by decreasing aldosterone secretion, which leads to potassium retention in the body. Hyperkalemia is a potential side effect of ACE inhibitors and should be closely monitored, as it can have serious consequences such as affecting cardiac function.

3. A client who delivered a 7-pound infant 12 hours ago is complaining of a severe headache. The client's blood pressure is 110/70, respiratory rate is 18 breaths/minute, heart rate is 74 beats/minute, and temperature is 98.6º F. The client's fundus is firm and one fingerbreadth above the umbilicus. What action should the healthcare team implement first?

• A. Notify the healthcare provider of the assessment findings.
• B. Determine if the client received anesthesia during delivery.
• C. Assign a licensed nurse to reassess the client's vital signs.
• D. Obtain a STAT hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct action to implement first is to determine if the client received anesthesia during delivery. Anesthesia can be a potential cause of postpartum headaches. This information is crucial in assessing and managing the client's condition effectively before considering other interventions. It helps in identifying possible contributing factors to the client's complaint of a severe headache and guides the healthcare team in providing appropriate care and treatment.

4. A client with newly diagnosed hypertension is prescribed enalapril (Vasotec). Which instruction should the nurse provide to the client?

• A. Increase your intake of potassium-rich foods.
• B. Report any persistent cough to your healthcare provider.
• C. Take the medication with a full meal.
• D. Avoid grapefruit juice while taking this medication.

Correct answer: B

Rationale: The correct instruction for the nurse to provide the client taking enalapril (Vasotec) is to report any persistent cough to their healthcare provider. Enalapril can cause a side effect of a persistent cough, and it is essential for the healthcare provider to be notified if this occurs to evaluate the need for a medication adjustment or change. Choices A, C, and D are incorrect. Increasing potassium-rich foods is not specifically related to enalapril use; there is no requirement to take enalapril with a full meal, and avoiding grapefruit juice is more relevant for medications metabolized by the CYP3A4 enzyme, not typically for enalapril.

5. A 56-year-old woman with rheumatoid arthritis has severe joint pain and swelling in her hands. She has a history of peptic ulcer disease five years ago but presently has no GI symptoms. You elect to start her on an NSAID. Which of the following is correct?

• A. Proton-pump inhibitors and H2-blockers are equally effective in prophylaxis against NSAID-related GI toxicity.
• B. Misoprostol is superior to an H2-blocker in prophylaxis against NSAID-related GI toxicity.
• C. Sucralfate is not the drug of choice for prophylaxis in this patient.
• D. H. pylori infection can alter the risk for an NSAID-induced ulcer.

Correct answer: B

Rationale: In this scenario, the patient's history of peptic ulcer disease puts her at risk for NSAID-related GI toxicity. Misoprostol and proton-pump inhibitors have shown superiority over H2-blockers in preventing NSAID-related GI toxicity. H. pylori infection can indeed increase the risk of an NSAID-induced ulcer in infected patients who are starting NSAID therapy. Sucralfate has not been proven to be effective in prophylaxis against NSAID-related GI toxicity. Therefore, the correct choice is B, as misoprostol is the preferred option over an H2-blocker in this context.
