Nursing Elites

1. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.

2. The client is going for surgery and mentions their religious objection to blood transfusions. Which of the following responses would be most appropriate?

• A. "I can ask pastoral care to send someone to speak with you about this concern since it would not be safe to refuse a blood transfusion."?
• B. "I understand, and you have the right to refuse blood transfusions."?
• C. "While I understand, if there is excessive bleeding during surgery, we may need to transfuse blood to stabilize you."?
• D. "I have received a blood transfusion before, and I do not think you understand the risks versus the benefits of refusing this."?

Correct answer: B

Rationale: The most appropriate response is, '"I understand, and you have the right to refuse blood transfusions."? This answer shows respect for the client's autonomy and religious beliefs. It is crucial for healthcare providers to acknowledge and support a patient's decision-making regarding their care, even if it conflicts with medical advice. Option A is not ideal as it might seem dismissive of the client's beliefs. Option C introduces a potential negative outcome of refusing a blood transfusion, which could induce fear or coercion. Option D is inappropriate because it implies judgment and does not uphold the client's autonomy.

3. When observing a dressing change by a graduate nurse on a Stage III pressure ulcer to the greater trochanter by the staff nurse, a need for further teaching is indicated after the following observation by the nurse:

• A. The new graduate nurse irrigates the pressure ulcer with 50cc of NS.
• B. The new graduate irrigates the pressure ulcer with half-strength hydrogen peroxide.
• C. The new graduate packs the wound with sterile kerlix soaked in NS.
• D. The new graduate applies a Duoderm dressing over the wound after cleansing.

Correct answer: B

Rationale: The correct answer is that the new graduate irrigates the pressure ulcer with half-strength hydrogen peroxide. Pressure ulcers should not be cleaned with substances that are cytotoxic, such as hydrogen peroxide or betadine. This can cause further damage to the wound and delay the healing process. Choice A is incorrect because irrigating the pressure ulcer with normal saline is an appropriate practice. Choice C is incorrect because packing the wound with sterile kerlix soaked in normal saline is also an appropriate step. Choice D is incorrect because applying a Duoderm dressing after cleansing is a standard procedure in wound care.

4. A client with a nasogastric (NG) tube begins vomiting. What action should the nurse take?

• A. Retape the NG tube.
• B. Clamp the NG tube.
• C. Remove the NG tube.
• D. Check the NG tube placement.

Correct answer: D

Rationale: When a client with a nasogastric (NG) tube begins vomiting, the nurse should first check the NG tube placement. Vomiting can be a sign of tube displacement, which can lead to serious complications. Retaping the tube (Choice A), clamping it (Choice B), or removing it (Choice C) without first assessing its placement can be harmful or ineffective. Checking the NG tube placement is crucial as it ensures that the tube is in the correct position and prevents potential complications. Retaping the NG tube (Choice A) is incorrect because the priority is to check the placement first. Clamping the NG tube (Choice B) or removing it (Choice C) without verifying the placement can be dangerous if the tube is dislodged. Thus, these actions should not be taken before confirming the tube's position.

5. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?

• A. blood urea nitrogen
• B. serum calcium
• C. serum ammonia
• D. serum creatinine

Correct answer: C

Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.
