Nursing Elites

1. Some drugs are excreted into bile and delivered to the intestines. Prior to elimination from the body, the drug might be absorbed. This process is known as:

• A. hepatic clearance.
• B. total clearance.
• C. enterohepatic cycling.
• D. first-pass effect.

Correct answer: C

Rationale: The correct answer is 'enterohepatic cycling.' This process involves drugs being excreted into bile, delivered to the intestines, reabsorbed into the circulation, and can prolong the drug's presence in the body. 'Hepatic clearance' (Choice A) refers to the amount of drug eliminated by the liver. 'Total clearance' (Choice B) is the sum of all types of clearance including renal, hepatic, and respiratory. 'First-pass effect' (Choice D) is the amount of drug absorbed from the GI tract and metabolized by the liver before entering circulation, reducing the amount of drug available for systemic circulation.

2. The nurse is caring for a client with epilepsy who is being treated with carbamazepine (Tegretol). Which laboratory value might indicate a serious side effect of this drug?

• A. Uric acid of 5 mg/dL
• B. Hematocrit of 33%
• C. WBC 2,000 per cubic millimeter
• D. Platelets 150,000 per cubic millimeter

Correct answer: C

Rationale: Carbamazepine (Tegretol) can suppress the bone marrow, leading to a decrease in the white blood cell count. A laboratory value of WBC 2,000 per cubic millimeter indicates a serious side effect of the drug. Choices A and D are within normal limits, while choice B is at the lower limit of normal. Therefore, choices A, B, and D are incorrect.

3. The nurse is caring for a client scheduled for a surgical repair of a sacular abdominal aortic aneurysm. Which assessment is most crucial during the preoperative period?

• A. Assessment of the client's level of anxiety
• B. Evaluation of the client's exercise tolerance
• C. Identification of peripheral pulses
• D. Assessment of bowel sounds and activity

Correct answer: C

Rationale: The most crucial assessment during the preoperative period for a client with a sacular abdominal aortic aneurysm scheduled for surgical repair is the identification of peripheral pulses. During surgery, the aorta will be clamped, potentially affecting blood circulation to the kidneys and lower extremities. Therefore, it is essential for the nurse to assess peripheral pulses and monitor the return of circulation to the lower extremities postoperatively. Assessing the client's level of anxiety (Choice A) is important but not as crucial as ensuring adequate circulation. Evaluating exercise tolerance (Choice B) is not recommended preoperatively for this situation. Assessing bowel sounds and activity (Choice D) is of lesser concern compared to the critical need to monitor peripheral circulation.

4. The nurse is caring for a client scheduled for removal of a pituitary tumor using the transsphenoidal approach. The nurse should be particularly alert for:

• A. Nasal congestion
• B. Abdominal tenderness
• C. Muscle tetany
• D. Oliguria

Correct answer: A

Rationale: During the removal of a pituitary tumor using the transsphenoidal approach, nasal congestion is a significant concern as it can further obstruct the airway. This can be due to mucosal swelling, bleeding, or edema resulting from the surgery. Nasal congestion requires immediate attention to prevent airway compromise. Abdominal tenderness, muscle tetany, and oliguria are not directly associated with the pituitary gland or the transsphenoidal approach, making them incorrect choices. Abdominal tenderness is more common in abdominal or pelvic surgeries due to intra-abdominal issues. Muscle tetany is related to electrolyte imbalances or neuromuscular disorders, not specific to pituitary surgery. Oliguria is a concern in renal-related conditions, not typically in pituitary tumor surgeries.

5. The licensed practical nurse is working with a registered nurse and a patient care assistant. Which of the following clients should be cared for by the registered nurse?

• A. A client 2 days post-appendectomy
• B. A client 1 week post-thyroidectomy
• C. A client 3 days post-splenectomy
• D. A client 2 days post-thoracotomy

Correct answer: D

Rationale: The correct answer is a client 2 days post-thoracotomy because this client is the most critical and requires the expertise of a registered nurse. Clients A and B are stable and ready for discharge after their respective surgeries (appendectomy and thyroidectomy). Client C, who is 3 days post-splenectomy, is also stable enough to be cared for by a licensed practical nurse as they are in a stable condition and do not have immediate critical needs. Therefore, the registered nurse should care for the client 2 days post-thoracotomy due to the critical nature of the procedure and the immediate postoperative care required.
