Nursing Elites

1. The physician has ordered sodium warfarin (Coumadin) for the client with thrombophlebitis. The order should be entered to administer the medication at:

• A. 900
• B. 1200
• C. 1700
• D. 2100

Correct answer: C

Rationale: Sodium warfarin is typically administered in the late afternoon, around 1700 hours. This timing allows for accurate bleeding times to be drawn in the morning. Administering it at 0900 (choice A) would not align with this schedule and may affect the monitoring of bleeding times. Choice B (1200) is midday, which is not the recommended time for sodium warfarin administration. Choice D (2100) is in the evening, which is also not ideal. Therefore, the correct time for administering sodium warfarin is 1700 (choice C).

2. Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?

• A. 0.9% sodium chloride
• B. 5% dextrose in water solution
• C. Sterile water
• D. Heparin sodium

Correct answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, Heparin sodium, is an anticoagulant and is not routinely used to flush an IV device before and after the administration of blood.

3. A two-year-old has been in the hospital for 3 weeks and has seldom seen family members due to isolation precautions. Which of the following hospitalization changes is most likely to be occurring?

• A. Guilt
• B. Trust
• C. Separation anxiety
• D. Shame

Correct answer: C

Rationale: The correct answer is 'Separation anxiety.' Separation anxiety is a common response in young children when they are separated from their primary caregivers for extended periods. In this case, the two-year-old being in the hospital for three weeks and not being able to see family members due to isolation precautions can trigger separation anxiety. 'Guilt' is a feeling of responsibility for wrongdoing, which is not the most likely change occurring in this scenario. 'Trust' involves reliance and confidence in others, not typically associated with prolonged separation from family. 'Shame' is a negative emotion related to feeling disgrace, which is not the most appropriate response in this hospitalization situation.

4. 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.

5. A client reports that someone is in the room and trying to kill him. The nurse's best response is:

• A. "No one is in your room. Let's get you more medicine."?
• B. "I do not see anyone, but you seem to be very frightened."?
• C. "No one can hurt you here."?
• D. "Just tell the person to go away."?

Correct answer: B

Rationale: When a client reports hallucinations or delusions, it is crucial to respond in a non-confrontational and empathetic manner. Choice B acknowledges the client's fear without confirming the delusion, showing understanding, and providing reassurance. This response validates the client's feelings without reinforcing the false belief. The other responses in choices A, C, and D dismiss the client's feelings or perceptions, which can escalate the situation and harm the therapeutic relationship.
