Nursing Elites

1. A nurse is caring for four clients. The nurse should observe which of the following clients for a risk of vitamin B6 deficiency?

• A. A client who has cystic fibrosis
• B. A client who has chronic alcohol use disorder
• C. A client who takes phenytoin for a seizure disorder
• D. A client who is prescribed rifampin for tuberculosis

Correct answer: B

Rationale: Chronic alcohol use disorder can lead to vitamin B6 deficiency due to impaired absorption and increased excretion of the vitamin. While clients with cystic fibrosis may be at risk for fat-soluble vitamin deficiencies, such as vitamins A, D, E, and K, they are not specifically at high risk for vitamin B6 deficiency. Clients taking phenytoin are at risk for folate deficiency, not vitamin B6. Clients prescribed rifampin for tuberculosis are at risk for vitamin D deficiency, not vitamin B6.

2. The nurse is caring for a client with a history of peptic ulcer disease. Which of these findings would be most concerning to the nurse?

• A. A heart rate of 72 beats per minute
• B. A hemoglobin level of 12 g/dL
• C. The client reports black, tarry stools
• D. The client reports nausea and vomiting

Correct answer: C

Rationale: Black, tarry stools can indicate gastrointestinal bleeding, which is a serious complication of peptic ulcer disease. This finding suggests active bleeding in the gastrointestinal tract, requiring immediate attention. A normal heart rate of 72 beats per minute (choice A) is within the expected range. A hemoglobin level of 12 g/dL (choice B) is also within normal limits. Nausea and vomiting (choice D) are common symptoms associated with peptic ulcer disease but may not necessarily indicate active bleeding like black, tarry stools.

3. After a myocardial infarction, a client is placed on a sodium-restricted diet. When the nurse is teaching the client about the diet, which meal plan would be the most appropriate?

• A. 3 oz. broiled fish, 1 baked potato, 1/2 cup canned beets, 1 orange, and milk
• B. 3 oz. canned salmon, fresh broccoli, 1 biscuit, tea, and 1 apple
• C. A bologna sandwich, fresh eggplant, 2 oz fresh fruit, tea, and apple juice
• D. 3 oz. turkey, 1 fresh sweet potato, 1/2 cup fresh green beans, milk, and 1 orange

Correct answer: D

Rationale: The most appropriate meal plan for a client following a myocardial infarction and placed on a sodium-restricted diet should include fresh ingredients with low sodium content to promote heart health. Option D, which consists of 3 oz. turkey, 1 fresh sweet potato, 1/2 cup fresh green beans, milk, and 1 orange, aligns best with these requirements. Option A contains canned beets, which are typically high in sodium. Option B includes canned salmon, which may have added sodium. Option C has a bologna sandwich, which is processed and high in sodium. Therefore, Option D is the most suitable choice for a client needing a low-sodium diet after a heart attack.

4. A client is diagnosed with methicillin-resistant Staphylococcus aureus pneumonia. What type of isolation is most appropriate for this client?

• A. Reverse
• B. Airborne
• C. Standard precautions
• D. Contact

Correct answer: D

Rationale: The correct answer is 'D: Contact.' Contact precautions are necessary for clients with MRSA pneumonia to prevent the spread of the resistant bacteria. MRSA is primarily spread by direct contact, so using contact precautions, such as wearing gloves and gowns, is essential. Choice A, 'Reverse,' is not a type of isolation precaution. Choice B, 'Airborne,' is not the appropriate isolation for MRSA pneumonia, as MRSA is not transmitted through the airborne route. Choice C, 'Standard precautions,' are important for all clients, but for MRSA pneumonia specifically, contact precautions are more targeted and necessary.

5. The nurse is reviewing laboratory results on a client with acute renal failure. Which one of the following should be reported immediately?

• A. Blood urea nitrogen 50 mg/dl
• B. Hemoglobin of 10.3 g/dl
• C. Venous blood pH 7.30
• D. Serum potassium 6 mEq/L

Correct answer: D

Rationale: A serum potassium level of 6 mEq/L indicates hyperkalemia, which can be life-threatening and requires immediate intervention. Hyperkalemia can lead to dangerous cardiac arrhythmias and must be addressed promptly. The other options are not as urgent. A blood urea nitrogen level of 50 mg/dl may indicate kidney dysfunction but does not require immediate intervention. Hemoglobin of 10.3 g/dl may suggest anemia, which needs management but is not an immediate threat. A venous blood pH of 7.30 may indicate acidosis, which is concerning but not as acutely dangerous as hyperkalemia.
