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. When assessing a client in crisis, what should the nurse prioritize?

• A. Allowing the client to work through independent problem-solving.
• B. Completing an in-depth evaluation of stressors and responses to the situation.
• C. Focusing on immediate stress reduction.
• D. Recommending ongoing therapy.

Correct answer: C

Rationale: When a client is in crisis, the nurse's priority is to focus on immediate stress reduction. Crisis intervention aims to stabilize the client in the present moment by addressing the most pressing issues. Allowing the client to work through independent problem-solving (Choice A) may not be appropriate during a crisis as they might need immediate support. Completing an in-depth evaluation of stressors (Choice B) is important but not the immediate priority during a crisis. Recommending ongoing therapy (Choice D) may be considered later, but the immediate focus should be on reducing the client's stress and stabilizing the situation.

3. The client is taking rifampin 600mg po daily to treat his tuberculosis. Which action by the nurse indicates understanding of the medication?

• A. Telling the client that the medication will need to be taken with juice
• B. Telling the client that the medication will change the color of the urine
• C. Telling the client to take the medication before going to bed at night
• D. Telling the client to take the medication if night sweats occur

Correct answer: B

Rationale: The correct answer is telling the client that the medication will change the color of the urine. Rifampin can change the color of the urine and body fluid. Teaching the client about these changes is important as the client might think this is a complication. Answer A is incorrect because there is no specific requirement to take rifampin with juice. Answer C is incorrect because rifampin should be taken at consistent times, not necessarily before going to bed. Answer D is incorrect as rifampin should be taken regularly as prescribed, not based on symptoms like night sweats.

4. A client arrives in the emergency room with a possible fractured femur. The nurse should anticipate an order for:

• A. Trendelenburg position
• B. Ice to the entire extremity
• C. Buck's traction
• D. An abduction pillow

Correct answer: C

Rationale: The correct answer is Buck's traction. This intervention is used to realign the fractured femur, reduce spasms, and alleviate pain. Placing the client in the Trendelenburg position is inappropriate for a femur fracture, making answer A incorrect. While ice may be used post-repair, applying it to the entire extremity is unnecessary, so answer B is wrong. An abduction pillow is typically employed following a total hip replacement, not for a fractured femur, rendering answer D incorrect.

5. A client receiving preoperative instructions asks questions repeatedly about when to stop eating the night before the procedure. The nurse tries to refocus the client. The nurse notes that the client is frequently startled by noises in the hall. Assessment reveals rapid speech, trembling hands, tachypnea, tachycardia, and elevated blood pressure. The client admits to feeling nervous and having trouble sleeping. Based on the assessment, the nurse documents that the client has:

• A. mild anxiety.
• B. moderate anxiety.
• C. severe anxiety.
• D. a panic attack.

Correct answer: C

Rationale: The correct answer is 'severe anxiety.' In severe anxiety, a person focuses on small or scattered details and is unable to solve problems. The client's symptoms of rapid speech, trembling hands, tachypnea, tachycardia, elevated blood pressure, feeling nervous, and having trouble sleeping indicate severe anxiety. Mild anxiety enhances the ability to learn and solve problems, while moderate anxiety narrows the perceptual field but allows the client to notice things brought to their attention. During a panic attack, a person is disorganized, hyperactive, or unable to speak or act, which is not the case in this scenario.
