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. 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).

3. A 6-month-old client is admitted with possible intussusception. Which question during the nursing history is least helpful in obtaining information regarding this diagnosis?

• A. "Tell me about his pain."?
• B. "What does his vomit look like?"?
• C. "Describe his usual diet."?
• D. "Have you noticed changes in his abdominal size?"?

Correct answer: C

Rationale: The least helpful question in obtaining information regarding intussusception is "Describe his usual diet."? This question is least relevant to the specific symptoms and presentation of intussusception. Choices A, B, and D are more directly related to symptoms commonly associated with intussusception and can provide important diagnostic clues. Asking about pain, vomit appearance, and changes in abdominal size can help in assessing the severity and progression of the condition, making them more crucial questions to ask in this scenario. Pain is a cardinal symptom of intussusception, changes in vomit appearance may indicate gastrointestinal issues, and alterations in abdominal size can signify the presence of a mass or obstruction, all of which are pertinent in diagnosing and managing intussusception.

4. A client with a diagnosis of Schizophrenia has been released from an acute care setting. The client had a prolonged recovery from relapse. One of the parents says to the discharge nurse, 'I do not understand what is going on. The hospital said she was better, but all she does is sit around all day and smoke. We cannot get her to go to the vocational training you arranged.' The nurse recognizes that more teaching is needed about

• A. the pathophysiology and behavioral manifestations of schizophrenia.
• B. support groups that can help the parents cope with their frustration.
• C. the prolonged recovery time and side effects of medications to prevent relapse.
• D. motivational techniques that are effective in engaging clients with schizophrenia.

Correct answer: C

Rationale: The nurse conducting discharge teaching must emphasize the extended recovery process and the potential side effects of medications used to prevent relapse in individuals with schizophrenia. In this scenario, it is crucial for the parents to understand that the client's behavior may be influenced by the medication's sedative qualities and the time required for full recovery. While support groups can assist caregivers in coping with their emotions and providing better care, the priority here is educating on the recovery process and medication effects. Motivational techniques are beneficial but may not be the immediate focus in this situation.

5. When supporting a family who has just experienced a sudden and unexpected death, the nurse needs to know:

• A. that survivors have greater emotional turmoil and shock than when death is expected.
• B. that survivors have less emotional turmoil and shock than when death is expected.
• C. that survivors have the same emotional turmoil and shock as when death is expected.
• D. that survivors have little emotional turmoil and shock because they were not there.

Correct answer: A

Rationale: The correct answer is that survivors have greater emotional turmoil and shock than when death is expected. Sudden death produces more emotional turmoil and shock in survivors compared to gradual, expected death. Survivors of sudden death do not have the opportunity to engage in anticipatory grief. The unexpectedness of sudden death is the most disturbing and unbalancing factor, leading to heightened emotional turmoil and shock. Choice B is incorrect as survivors of sudden death experience more emotional turmoil and shock. Choice C is incorrect because sudden death brings about a different level of emotional turmoil and shock. Choice D is incorrect as survivors of sudden and unexpected death still go through significant emotional distress.
