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. A corporate executive works 60-80 hours a week. The client is experiencing some physical signs of stress. The nurse teaches the client biofeedback techniques. This is an example of which of the following health-promotion interventions?

• A. structure
• B. relaxation technique
• C. time management
• D. regular exercise

Correct answer: C

Rationale: The correct answer is 'relaxation technique.' Biofeedback techniques are a form of relaxation technique that can help individuals quiet the mind, release tension, and counteract responses to stress. Teaching biofeedback techniques to the client aims to promote relaxation and stress management. Choice A, 'structure,' does not directly relate to teaching biofeedback techniques. Choice C, 'time management,' focuses on organizing tasks efficiently, not on relaxation techniques. Choice D, 'regular exercise,' although beneficial for overall health, is not specifically related to the teaching of biofeedback techniques for stress relief.

3. A client has been taking alprazolam (Xanax) for four years to manage anxiety. The client reports taking 0.5 mg four times a day. Which statement indicates that the client understands the nurse's teaching about discontinuing the medication?

• A. "I can drink alcohol now that I am decreasing my Xanax."?
• B. "I should not take another Xanax pill. Here is what is left of my last prescription."?
• C. "I should take three pills per day next week, then two pills for one week, then one pill for one week."?
• D. "I can expect to be sleepy for several days after stopping the medicine."?

Correct answer: C

Rationale: Explanation: When discontinuing alprazolam (Xanax) after long-term use, it is crucial to taper the dosage gradually to prevent withdrawal symptoms. The correct statement indicates an understanding of this by planning a structured decrease in dosage over time. Choice A is incorrect as drinking alcohol while decreasing Xanax can be dangerous and is not recommended. Choice B is incorrect as abruptly stopping Xanax is not safe and can lead to withdrawal symptoms. Choice D is incorrect as expecting to be sleepy for several days after stopping the medication does not address the need for a gradual tapering process to avoid withdrawal symptoms.

4. 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.

5. The LPN is teaching a first-time mother about breastfeeding her newborn. Which statement, if made by the mother, would reflect that the teaching had been successful?

• A. "My baby should be having at least 4-6 wet diapers a day until 1 month."?
• B. "It's nice that breastfed babies eat a bit less than formula-fed babies."?
• C. "My baby should be nursing 8-12 times a day during this period."?
• D. "I'm a little nervous about my milk coming in tomorrow. I've heard it's uncomfortable."?

Correct answer: C

Rationale: The correct answer is, '"My baby should be nursing 8-12 times a day during this period."?' This statement indicates successful teaching because newborns should nurse 8-12 times during the newborn period to ensure they receive adequate nutrition and establish a good milk supply. This frequency helps in meeting the baby's demands for growth and development. Choice A is incorrect because while it mentions the appropriate number of wet diapers a day once the mother's milk comes in, it does not reflect successful teaching about breastfeeding frequency. Choice B is incorrect because it discusses feeding amounts in comparison to formula-fed babies, which is not a direct indicator of successful breastfeeding teaching. Choice D is incorrect because it focuses on the mother's concerns about milk coming in, not on understanding the feeding frequency needed for the newborn.
