1. A client with a severe head injury is admitted to the intensive care unit (ICU). Which finding should the nurse report to the healthcare provider immediately?
- A. Urine output of 100 mL/hour.
- B. Intracranial pressure (ICP) of 20 mm Hg.
- C. Respiratory rate of 12 breaths/minute.
- D. Mean arterial pressure (MAP) of 70 mm Hg.
Correct answer: B
Rationale: An Intracranial Pressure (ICP) of 20 mm Hg is at the upper limit of normal and may indicate increased intracranial pressure, which is a critical finding in a client with a severe head injury. Elevated ICP can lead to further brain damage and must be addressed promptly to prevent complications such as herniation. Monitoring and managing ICP are crucial in the care of patients with head injuries in the ICU.
2. 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.
3. Aspirin is prescribed for a 9-year-old child with rheumatic fever to control the inflammatory process, promote comfort, and reduce fever. What intervention is most important for the nurse to implement?
- A. Instruct the parents to hold the aspirin until the child has first had a tepid sponge bath.
- B. Administer the aspirin with at least two ounces of water or juice.
- C. Notify the healthcare provider if the child complains of ringing in the ears.
- D. Advise the parents to question the child about seeing yellow halos around objects.
Correct answer: C
Rationale: In children, ringing in the ears (tinnitus) can be a sign of aspirin toxicity. Aspirin toxicity can be particularly concerning in children and can lead to serious complications. Therefore, it is crucial for the nurse to prioritize monitoring for signs of aspirin toxicity, such as tinnitus, and promptly notify the healthcare provider if such symptoms occur.
4. 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.
5. In a patient with a history of chronic iron deficiency anemia requiring a recent blood transfusion and an extensive GI work-up, which statement is true based on their medications?
- A. A dedicated small bowel series has a high likelihood of being positive
- B. 81 mg of aspirin per day decreases the benefit of using a COX II inhibitor
- C. The patient should have a provocative arteriogram with heparin infusion to identify the source of blood loss
- D. Hormonal therapy has been shown to be effective in decreasing blood loss due to arteriovenous malformations
Correct answer: B
Rationale: The correct answer is B. Taking even a low dose of aspirin per day, such as 81 mg, can reduce the protective effect on the gastrointestinal mucosa that is gained from using a COX II selective inhibitor. Aspirin can increase the risk of gastrointestinal bleeding, which can counteract the benefits of COX II inhibitors in protecting the stomach lining.
