Nursing Elites

1. A nurse is assessing the chest tube drainage system of a postoperative client who has undergone a right upper lobectomy. The closed drainage system contains 300 mL of bloody drainage, and the nurse notes intermittent bubbling in the water seal chamber. One hour after the initial assessment, the nurse notes that the bubbling in the water seal chamber is now constant, and the client appears dyspneic. On the basis of these findings, the nurse should first assess:

• A. The client’s vital signs
• B. The amount of drainage
• C. The client’s lung sounds
• D. The chest tube connections

Correct answer: D

Rationale: The client’s dyspnea is most likely related to an air leak caused by a loose connection in the chest tube system. Checking the chest tube connections should be the initial action because correcting an air leak can quickly resolve the client's symptoms. If a leak is found and corrected, the dyspnea should improve. Assessing the client’s vital signs (Option A) is important, but addressing the potential cause of dyspnea takes precedence. Monitoring the amount of drainage (Option B) is necessary for assessing the client's overall condition, but in this case, the dyspnea is likely due to an air leak. Checking the client’s lung sounds (Option C) is essential for respiratory assessment, but addressing the air leak should be the immediate priority to ensure adequate lung expansion and oxygenation.

2. A client is being prepared for transfer to the operating room. Which of the following actions should the nurse take in the care of this client at this time?

• A. Ensuring that the client has voided
• B. Administering all daily medications
• C. Practicing postoperative breathing exercises
• D. Verifying that the client has not eaten for the last 24 hours

Correct answer: A

Rationale: The nurse should ensure that the client has voided, especially if a Foley catheter is not in place. This step is important to prevent urinary retention during the surgical procedure. Administering all daily medications just before surgery is not standard practice. The physician typically provides specific orders regarding which medications can be taken with a sip of water before surgery. Postoperative breathing exercises are usually taught after surgery to prevent complications like atelectasis. Verifying that the client has not eaten for the last 24 hours is not a standard preoperative practice; instead, the client is usually instructed to fast for a specific period before surgery to reduce the risk of aspiration during anesthesia.

3. 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.

4. When assessing an individual with peripheral vascular disease, which clinical manifestation would indicate complete arterial obstruction in the lower left leg?

• A. Aching pain in the left calf.
• B. Burning pain in the left calf.
• C. Numbness and tingling in the left leg.
• D. Coldness of the left foot and ankle.

Correct answer: D

Rationale: Coldness of the left foot and ankle is the correct clinical manifestation indicating complete arterial obstruction in the lower left leg. Complete arterial obstruction results in reduced blood flow, leading to decreased temperature in the affected area. Aching pain (Choice A) and burning pain (Choice B) are more commonly associated with partial obstructions or ischemia, while numbness and tingling (Choice C) can be indicative of nerve involvement or compromised circulation, but not specifically complete arterial obstruction. The coldness in the foot and ankle is a result of severely reduced blood flow, which impairs the delivery of oxygen and nutrients to the tissues in that area, leading to a lower temperature. This symptom is a critical indicator of a more severe blockage compared to the other options provided.

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.
