Nursing Elites

1. Mrs. Owens is the 81-year-old mother of Jonathan, who is 54 years old. Jonathan has had schizophrenia since he was 16 years old. Which of Mrs. Owens's concerns is likely to predominate?

• A. "Will my retirement funds outlast me?"?
• B. "Who will handle my funeral arrangements?"?
• C. "What will become of Jonathan when I am gone?"?
• D. "How can I communicate effectively with Jonathan's physician?"?

Correct answer: C

Rationale: The most prominent concern for Mrs. Owens is likely what will happen to her son, Jonathan, after she passes away. While retirement fund sustainability is important, it is not likely to be her primary concern. Funeral arrangements, although significant, are secondary to the welfare of her son with schizophrenia. The question of how to communicate with Jonathan's physician is less likely to be a predominant concern since Mrs. Owens has likely already addressed this issue over the 38 years of managing her son's care.

2. How should Lasix be administered to prevent hypotension?

• A. By administering it over 1-2 minutes
• B. By hanging it IV piggyback
• C. With normal saline only
• D. By administering it through a venous access device

Correct answer: A

Rationale: Lasix should be administered over 1-2 minutes at approximately 1mL per minute to prevent hypotension. This slow administration helps to reduce the risk of adverse effects such as sudden drops in blood pressure. Choice B is incorrect because Lasix does not need to be hung IV piggyback, choice C is incorrect as Lasix administration does not require it to be mixed with normal saline only, and choice D is incorrect as Lasix does not have to be specifically administered through a venous access device (VAD) to prevent hypotension.

3. 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.

4. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

5. A client with glomerulonephritis is placed on a low-sodium diet. Which of the following snacks is suitable for the client with sodium restriction?

• A. Peanut butter cookies
• B. Grilled cheese sandwich
• C. Cottage cheese and fruit
• D. Fresh peach

Correct answer: D

Rationale: The correct answer is a fresh peach. It is the most suitable snack for a client with sodium restriction as it is naturally low in sodium. Peanut butter cookies (choice A), grilled cheese sandwich (choice B), and cottage cheese and fruit (choice C) contain higher amounts of sodium, making them unsuitable choices for someone on a low-sodium diet. Fresh fruits like peaches are excellent options for individuals on a low-sodium diet as they are not only low in sodium but also provide essential nutrients and hydration.
