Nursing Elites

1. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.

2. Which assessment finding indicates to the nurse a client's readiness for pulmonary function tests?

• A. Expresses an understanding of the procedure.
• B. NPO for 6 hrs.
• C. No known drug allergies.
• D. Intravenous access intact.

Correct answer: A

Rationale: The correct answer is A: 'Expresses an understanding of the procedure.' This choice indicates that the client is mentally prepared for the pulmonary function tests, as understanding the procedure shows readiness and cooperation. Choices B, C, and D are incorrect. Choice B, 'NPO for 6 hrs,' pertains to fasting status and is not directly related to readiness for the test. Choice C, 'No known drug allergies,' is important information but does not specifically indicate readiness for pulmonary function tests. Choice D, 'Intravenous access intact,' is related to vascular access and not a direct indicator of readiness for the pulmonary function tests.

3. The nurse is planning care for a client admitted with a diagnosis of pheochromocytoma. Which intervention has the highest priority for inclusion in this client's plan of care?

• A. Record urine output every hour
• B. Monitor blood pressure frequently
• C. Evaluate neurological status
• D. Maintain seizure precautions

Correct answer: B

Rationale: Monitoring blood pressure frequently is the highest priority intervention for a client diagnosed with pheochromocytoma. This rare tumor can lead to life-threatening hypertension due to catecholamine secretion. Evaluating neurological status and maintaining seizure precautions are important but are not the highest priority in this case. Recording urine output, though essential for overall assessment, is not the priority compared to monitoring blood pressure in a client with pheochromocytoma.

4. The nurse reviews the laboratory findings of a client with an open fracture of the tibia. The white blood cell (WBC) count and erythrocyte sedimentation rate (ESR) are elevated. Before reporting this information to the healthcare provider, what assessment should the nurse obtain?

• A. Appearance of wound
• B. Pain level
• C. Presence of fever
• D. Mobility status

Correct answer: A

Rationale: The correct answer is A: Appearance of wound. Elevated WBC and ESR levels suggest a possible infection in the client with an open fracture. Assessing the wound's appearance is crucial to evaluate for signs of infection, such as redness, warmth, swelling, or drainage. By assessing the wound first, the nurse can provide important information to the healthcare provider regarding the potential infection, which may require immediate intervention. Choices B, C, and D are important assessments in caring for a client with an open fracture; however, in this scenario, the priority is to assess the wound for signs of infection due to the elevated WBC and ESR levels.

5. The healthcare provider is assessing a client with left-sided heart failure. Which laboratory value should be monitored closely?

• A. Serum sodium of 135 mEq/L
• B. Serum potassium of 4.5 mEq/L
• C. Serum creatinine of 1.8 mg/dl
• D. Serum glucose of 200 mg/dl

Correct answer: C

Rationale: In a client with left-sided heart failure, monitoring serum creatinine is crucial to evaluate kidney function and fluid balance. Elevated creatinine levels can indicate impaired kidney function, which is common in heart failure due to decreased cardiac output and renal perfusion. Serum sodium levels (choice A) are important but are more closely associated with fluid balance and heart failure exacerbation. Serum potassium (choice B) is also important to monitor, but it is more closely linked to cardiac arrhythmias rather than kidney function. Serum glucose levels (choice D) are significant but are not the priority for monitoring in left-sided heart failure.
