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. When preparing a client who has had a total laryngectomy for discharge, what instruction is most important for the nurse to include in the discharge teaching?

• A. Recommend that the client carry suction equipment at all times.
• B. Instruct the client to have writing materials with them at all times.
• C. Tell the client to carry a medic alert card stating that they are a total neck breather.
• D. Tell the client not to travel alone.

Correct answer: C

Rationale: The most crucial instruction for a client who has had a total laryngectomy is to carry a medic alert card stating that they are a total neck breather. This is important because if they experience a cardiac arrest, mouth-to-neck breathing may be required. Choice A about carrying suction equipment is not the most critical as the client may not always need it. Choice B is not as essential as having a medic alert card. Choice D is not directly related to the client's safety due to their laryngectomy.

3. After educating a client with a history of renal calculi, the nurse assesses the client’s understanding. Which statement made by the client indicates a correct understanding of the teaching?

• A. I should drink at least 3 liters of fluid every day.
• B. I will eliminate all dairy or sources of calcium from my diet.
• C. Aspirin and aspirin-containing products can lead to stones.
• D. The doctor can give me antibiotics at the first sign of a stone.

Correct answer: A

Rationale: To prevent the formation of renal calculi, it is essential to maintain adequate hydration as dehydration can contribute to the precipitation of minerals leading to stone formation. Therefore, the correct statement indicating understanding of the teaching is choice A. Increasing fluid intake helps dilute urine and reduces the risk of stone formation. Eliminating all sources of calcium is not recommended as calcium is essential for various bodily functions and eliminating it can lead to other health issues. Aspirin and aspirin-containing products do not directly cause kidney stones. Antibiotics are not used to prevent or treat renal calculi, as they are not caused by bacterial infections.

4. To help minimize the risk of postoperative respiratory complications after a hypophysectomy, during preoperative teaching, the nurse should instruct the client how to:

• A. Use incentive spirometry.
• B. Turn in bed.
• C. Take deep breaths.
• D. Cough.

Correct answer: C

Rationale: The correct answer is to instruct the client on how to take deep breaths. Deep breathing exercises are essential in preventing postoperative respiratory complications like atelectasis by promoting lung expansion. Using incentive spirometry is a more specific and advanced method of promoting deep breathing and lung expansion, making it a better choice than just turning in bed. While turning in bed may help with overall comfort and positioning, it is not as directly related to respiratory complications as deep breathing exercises. Coughing, although important for clearing secretions, is not as effective in preventing atelectasis as deep breathing exercises.

5. A client has undergone insertion of a permanent pacemaker. When developing a discharge teaching plan, the nurse writes a goal of, 'The client will verbalize symptoms of pacemaker failure.' Which symptoms are most important to teach the client?

• A. Facial flushing.
• B. Fever.
• C. Pounding headache.
• D. Feelings of dizziness.

Correct answer: D

Rationale: The correct answer is 'D: Feelings of dizziness.' Feelings of dizziness may occur as a result of a decreased heart rate, leading to decreased cardiac output, which can be an indication of pacemaker failure. Teaching the client to recognize symptoms of decreased cardiac output, like dizziness, is crucial for early detection of pacemaker malfunction. Choices A, B, and C are less specific to pacemaker failure and are not commonly associated with this condition. Facial flushing, fever, and pounding headache are not typical signs of pacemaker failure and are not directly related to cardiac output, making them less relevant for teaching the client about pacemaker failure.
