Nursing Elites

1. A patient with tuberculosis is started on rifampin. What advice should the nurse provide?

• A. Limit intake of green leafy vegetables.
• B. Expect orange-red discoloration of body fluids.
• C. Avoid exposure to sunlight.
• D. Take the medication with antacids.

Correct answer: B

Rationale: The correct advice for a patient starting rifampin is to expect orange-red discoloration of body fluids. Rifampin can cause harmless orange-red discoloration of body fluids, which may include urine, sweat, saliva, and tears. It is important for the patient to be aware of this side effect as it can stain clothing and contact lenses. Limiting the intake of green leafy vegetables is not necessary with rifampin. Avoiding exposure to sunlight is more commonly associated with other medications like tetracyclines, not rifampin. Taking rifampin with antacids is not recommended as antacids can reduce the absorption of rifampin, decreasing its effectiveness in treating tuberculosis.

2. A client with a history of diabetes mellitus presents with confusion, sweating, and palpitations. What should the nurse do first?

• A. Check the client's blood glucose level.
• B. Administer 10 units of insulin.
• C. Give the client a high-protein snack.
• D. Measure the client's blood pressure.

Correct answer: A

Rationale: The correct first action for a client presenting with confusion, sweating, and palpitations, suggestive of hypoglycemia, is to check the client's blood glucose level. This step helps to confirm if the symptoms are due to low blood sugar levels and guides appropriate interventions. Administering insulin without knowing the current blood glucose level can be dangerous and is not recommended as the initial step. Offering a high-protein snack may be necessary after confirming hypoglycemia, but checking the blood glucose level takes precedence. Measuring blood pressure is not the priority in this situation; addressing hypoglycemia is the immediate concern.

3. 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.

4. What is the primary action of a short-acting beta2-agonist (SABA) prescribed to a patient with an acute asthma exacerbation?

• A. Reduce inflammation
• B. Relieve bronchospasm
• C. Thin respiratory secretions
• D. Suppress cough

Correct answer: B

Rationale: The correct answer is B: Relieve bronchospasm. The primary action of short-acting beta2-agonists (SABAs) is to relieve bronchospasm. These medications are bronchodilators that work by opening the airways, making breathing easier for patients experiencing asthma exacerbations. By relieving bronchospasm, SABAs help improve airflow and alleviate symptoms of asthma such as wheezing and shortness of breath. Choices A, C, and D are incorrect because SABAs do not primarily reduce inflammation, thin respiratory secretions, or suppress cough. While these actions may be part of asthma management, the immediate goal of using a SABA during an acute exacerbation is to quickly relieve bronchospasm and improve airflow.

5. 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.
