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. What should be the first action upon the discovery of an electrical fire?

• A. Disconnect the electrical power if it can be done safely
• B. Smother the source with an object like a blanket
• C. Saturate the source with water or another liquid
• D. Immediately activate the fire alarm

Correct answer: A

Rationale: The correct initial action upon discovering an electrical fire is to disconnect the electrical power if it can be done safely. This helps prevent the fire from spreading through the electrical system. Smothering the fire with a blanket is not recommended for electrical fires as it can fuel the fire. Saturating the source with water or other liquids is also not advised as it can lead to electric shock or spread the fire. Activating the fire alarm is important, but it should be done after disconnecting the power to prevent further escalation of the fire.

3. While repositioning a comatose client, the nurse senses a tingling sensation as she lowers the bed. What action should she take?

• A. Unplug the bed's power source.
• B. Remove the client from the bed immediately.
• C. Notify the biomedical department at once.
• D. Turn off the oxygen.

Correct answer: A

Rationale: The correct action for the nurse to take when sensing a tingling sensation while lowering the bed with a comatose client is to unplug the bed's power source. This should be the initial step as there may be a fault in the bed's grounding. Removing the client from the bed immediately is not safe until the electrical issue is resolved. Notifying the biomedical department is important but should come after ensuring the immediate safety of the client. Turning off the oxygen is not necessary unless there is a specific issue related to oxygen delivery, which is not indicated in this scenario.

4. Following abdominal surgery, a client has a nasogastric (NG) tube in place. What is the purpose of this tube immediately after surgery?

• A. simplify medication administration
• B. measure accurate input and output
• C. prevent accumulation of fluids and gas
• D. facilitate collection of specimens

Correct answer: C

Rationale: The correct answer is to prevent accumulation of fluids and gas. Immediately after abdominal surgery, the NG tube is used to keep the stomach decompressed, preventing the accumulation of fluids and gas. This helps in maintaining decompression to prevent surgical-site disruption and fluid loss through vomiting. Choices A, B, and D are incorrect because the primary purpose of the NG tube following abdominal surgery is to prevent complications related to fluid and gas build-up rather than simplifying medication administration, measuring input and output, or collecting specimens.

5. Which of the following statements by a client indicates adequate understanding of preparation for a lipoprotein fractionation test?

• A. "I cannot eat or drink after midnight."?
• B. "I cannot eat for 12 hours before the test."?
• C. "I need to limit my fluid intake."?
• D. "I need to ingest a lipid solution."?

Correct answer: B

Rationale: The correct statement regarding preparation for a lipoprotein fractionation test is that the client cannot eat for 12 hours before the test. It is important to note that the client can drink an unrestricted amount of water. Limiting fluid intake is not necessary for this test. There is no need for the client to ingest a lipid solution as part of the preparation. Therefore, the other choices are incorrect.
