Nursing Elites

1. Narrow therapeutic index medications:

• A. are drug formulations with limited pharmacokinetic variability.
• B. have limited value and require no monitoring of blood levels.
• C. have less than a twofold difference in minimum toxic levels and minimum effective concentration in the blood
• D. have limited potency and side effects.

Correct answer: C

Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug, indicating the safety margin. Narrow therapeutic index medications have a small difference between minimum toxic levels and minimum effective concentration in the blood, making them high-risk drugs that require close monitoring to avoid toxicity. Choice A is incorrect because pharmacokinetics refer to drug absorption, distribution, metabolism, and elimination, not the therapeutic index. Choice B is incorrect because narrow therapeutic index drugs necessitate monitoring due to their narrow margin of safety. Choice D is incorrect because narrow therapeutic index drugs do not necessarily have limited potency but are characterized by a small window between efficacy and toxicity.

2. Which of the following roommates would be most suitable for the client with myasthenia gravis?

• A. A client with hypothyroidism
• B. A client with Crohn's disease
• C. A client with pyelonephritis
• D. A client with bronchitis

Correct answer: A

Rationale: The most suitable roommate for the client with myasthenia gravis is the client with hypothyroidism because they are quiet. A client with Crohn's disease (choice B) would be up to the bathroom frequently due to gastrointestinal issues, which could disturb the roommate with myasthenia gravis. A client with pyelonephritis (choice C) suffering from a kidney infection will need to urinate frequently, causing disturbances. A client with bronchitis (choice D) will be coughing, potentially disrupting the rest and quiet environment needed by a roommate with myasthenia gravis to manage their symptoms effectively.

3. Upon arrival at the emergency room, the client presents with severe burns to the left arm, hands, face, and neck. What action should take priority?

• A. Starting an IV
• B. Applying oxygen
• C. Obtaining blood gases
• D. Medicating the client for pain

Correct answer: B

Rationale: In a client with severe burns to the face and neck, airway assessment and supplemental oxygen are crucial. Therefore, applying oxygen is the priority to ensure adequate oxygenation for the client. This intervention takes precedence over other actions to stabilize the client's condition. Starting an IV for fluid resuscitation is the next appropriate step following ensuring oxygenation (Choice A). While pain management is important, it is a secondary priority after ensuring oxygenation and fluid resuscitation, making medicating the client for pain a later intervention (Choice D). Obtaining blood gases (Choice C) is not the immediate priority in this scenario and would typically be ordered by the healthcare provider based on the client's condition and response to initial interventions.

4. The nurse is assigning staff for the day. Which assignment should be given to the nursing assistant?

• A. Taking the vital signs of the 5-month-old with bronchiolitis
• B. Taking the vital signs of the 10-year-old with a 2-day postappendectomy
• C. Administering medication to the 2-year-old with periorbital cellulitis
• D. Adjusting the traction of the 1-year-old with a fractured tibia

Correct answer: B

Rationale: The most appropriate assignment for a nursing assistant is to take the vital signs of a stable patient. A 10-year-old with a 2-day postappendectomy is considered stable, and routine vital signs monitoring can be safely delegated to a nursing assistant. Clients with bronchiolitis, periorbital cellulitis, and a fractured tibia require more specialized care and assessment by a licensed nurse. Bronchiolitis involves an airway alteration, periorbital cellulitis indicates an infection, and a fractured tibia may raise concerns of abuse. Therefore, options A, C, and D are incorrect for delegation to a nursing assistant.

5. 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.
