Nursing Elites

1. A 57-year-old woman is recently widowed. She states, "I will never be able to learn how to manage the finances. My husband did all of that."? Select the nurse's response that could help raise the client's self-esteem.

• A. "You feel inadequate because you have never learned to balance a checkbook."?
• B. "You should have insisted your husband teach you about the finances."?
• C. "You are strong and will learn how to manage your finances after a while."?
• D. "I believe in your strength to learn how to manage your finances in time."?

Correct answer: C

Rationale: The nurse should aim to boost the client's self-esteem by providing positive reinforcement. By stating, "You are strong and will learn how to manage your finances after a while,"? the nurse acknowledges the client's strength and capability, encouraging her to believe in herself. Choice A is incorrect as it focuses on the client's inadequacy rather than empowering her. Choice B places unnecessary blame on the client for not taking action in the past. Choice D, though positive, slightly alters the nurse's original phrase, making choice C the most appropriate response to uplift the client's self-esteem.

2. When assessing a client for risk of hyperphosphatemia, which piece of information is most important for the nurse to obtain?

• A. A history of radiation treatment in the neck region
• B. A history of recent orthopedic surgery
• C. A history of minimal physical activity
• D. A history of the client's food intake

Correct answer: A

Rationale: The correct answer is a history of radiation treatment in the neck region. Previous radiation to the neck may have damaged the parathyroid glands, which are crucial for calcium and phosphorus regulation. This damage can lead to disruptions in phosphorus levels, increasing the risk of hyperphosphatemia. Choices B, C, and D are not as directly related to phosphorus regulation. Orthopedic surgery, minimal physical activity, and food intake are more closely associated with calcium levels rather than phosphorus regulation. Therefore, it is essential for the nurse to focus on obtaining information about a history of radiation treatment in the neck region when assessing the risk of hyperphosphatemia in a client.

3. The client with diabetes is preparing for discharge. During discharge teaching, the nurse assesses the client's ability to care for himself. Which statement made by the client would indicate a need for follow-up after discharge?

• A. "I live by myself."?
• B. "I have trouble seeing."?
• C. "I have a cat in the house with me."?
• D. "I usually drive myself to the doctor."?

Correct answer: B

Rationale: A client with diabetes who has trouble seeing would require follow-up after discharge. The lack of visual acuity for the client preparing and injecting insulin might require help. Answers A, C, and D will not prevent the client from being able to care for himself and are incorrect. Living alone (Choice A) does not necessarily indicate a need for follow-up unless there are specific concerns. Having a cat at home (Choice C) and driving to the doctor (Choice D) are not direct indicators of the client's ability to care for himself.

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. Fat emulsions are frequently administered as a part of total parenteral nutrition. Which statement is true regarding fat emulsions?

• A. They have a high energy-to-fluid-volume ratio.
• B. Even though hypertonic, they are well tolerated.
• C. They are a basic solution due to the addition of sodium hydroxide (NaOH).
• D. The pH is alkaline, making them compatible with most medications.

Correct answer: A

Rationale: The correct statement is that fat emulsions have a high energy-to-fluid-volume ratio. Fat emulsions are formulated in 10%, 20%, and 30% solutions and supply 1.1, 2, and 3 kilocalories, respectively, for each milliliter. In comparison, a milliliter of 5% dextrose only supplies 0.17 kilocalories. Choices B, C, and D are incorrect. Choice B is false because fat emulsions are essentially pH neutral and isotonic, not hypertonic. Choice C is incorrect because fat emulsions are not basic solutions; they are essentially pH neutral. Choice D is incorrect as fat emulsions are not alkaline; they are pH neutral, making them compatible with most medications.
