Nursing Elites

1. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?

• A. To broaden the antibacterial spectrum.
• B. To decrease bacterial resistance.
• C. To improve the taste.
• D. To minimize toxic effects.

Correct answer: B

Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.

2. After a myocardial infarction, why is the hospitalized client taught to move the legs while resting in bed?

• A. Prepare the client for ambulation.
• B. Promote urinary and intestinal elimination.
• C. Prevent thrombophlebitis and blood clot formation.
• D. Decrease the likelihood of pressure ulcer formation.

Correct answer: C

Rationale: The correct answer is C. Moving the legs helps prevent thrombophlebitis and blood clot formation by promoting venous return in clients on bed rest. This prevents stasis and clot formation in the lower extremities. Choices A, B, and D are incorrect because the primary goal of moving the legs is to prevent thrombophlebitis and blood clot formation, rather than preparing for ambulation, promoting elimination, or decreasing pressure ulcer formation. Ambulation preparation involves different exercises, urinary and intestinal elimination are not directly related to leg movements, and pressure ulcer prevention is more related to repositioning and skin care.

3. An 81-year-old male client has emphysema. He lives at home with his cat and manages self-care with no difficulty. When making a home visit, the nurse notices that his tongue is somewhat cracked, and his eyeballs are sunken into his head. What nursing intervention is indicated?

• A. Help the client determine ways to increase his fluid intake.
• B. Obtain an appointment for the client to see a pulmonologist.
• C. Schedule an appointment with a nutritionist to assess the client's diet.
• D. Encourage the client to slightly increase his use of oxygen at night and to always use humidified oxygen.

Correct answer: A

Rationale: The correct nursing intervention in this scenario is to assist the client in finding ways to increase his fluid intake. Clients with COPD, including emphysema, should aim to consume at least three liters of fluids per day to help keep their mucus thin. As the disease progresses, these clients may decrease fluid intake due to various reasons. Suggesting creative methods, such as having disposable fruit juices readily available, can help the client meet this goal. Option B is incorrect as seeing an ear, nose, and throat specialist is not directly related to the client's symptoms. Option C is not the priority in this case, as the main concern is addressing the client's dehydration. Option D does not address the immediate need for managing the client's dehydration and is not the most appropriate intervention at this time.

4. A client is receiving continuous ambulatory peritoneal dialysis. Which of the following statements indicates the need for more teaching by the nurse?

• A. I should take all my medications every morning.
• B. The catheter should always remain in place.
• C. The catheter should be flushed daily with sterile saline.
• D. If I gain 2 pounds, I should skip dialysis that day.

Correct answer: D

Rationale: The correct answer is D. Gaining weight is a sign that the client may be retaining fluid, indicating a need for dialysis to remove excess fluid. Skipping dialysis based on weight gain can lead to fluid overload, electrolyte imbalances, and other serious complications. Choices A, B, and C are all correct statements regarding peritoneal dialysis care: taking medications as prescribed is essential for overall health, ensuring the catheter remains in place is crucial to prevent infection, and flushing the catheter with sterile saline daily helps maintain its patency and reduce the risk of infections.

5. Which of the following interventions is most appropriate for a patient with left-sided heart failure?

• A. Administering IV fluids.
• B. Administering oxygen.
• C. Administering diuretics.
• D. Administering antihypertensives.

Correct answer: B

Rationale: Administering oxygen is the most appropriate intervention for a patient with left-sided heart failure because it helps improve oxygenation. In left-sided heart failure, the heart struggles to pump oxygen-rich blood to the body, leading to inadequate oxygen supply to tissues. Administering oxygen can help alleviate symptoms of hypoxia and reduce the workload on the heart. IV fluids (Choice A) may exacerbate heart failure by increasing fluid volume, diuretics (Choice C) are used to reduce fluid overload in heart failure, and antihypertensives (Choice D) are more suitable for managing hypertension, which may be a comorbidity in heart failure but are not the primary intervention for left-sided heart failure.
