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 LPN is checking for residual before administering enteral feeding through a PEG tube. Which of these steps is incorrect?

• A. The LPN elevates the head of the bed by at least 30 degrees.
• B. If the residual is greater than 200mL, the LPN should not administer the enteral feeding.
• C. The LPN should discard the residual before administering the tube feeding.
• D. The residual pH level is tested to ensure appropriate placement.

Correct answer: C

Rationale: The incorrect step is choice C. The residual should be discarded before administering the tube feeding. Discarding the residual is essential to prevent contamination and ensure accurate measurement of the enteral feeding. Elevating the head of the bed by at least 30 degrees (choice A) is correct as it helps prevent aspiration during feeding. Testing the pH level of the residual (choice D) ensures proper placement of the tube. Withholding feeding if the residual is greater than 200mL (choice B) is crucial to prevent overfeeding, making this statement correct.

3. When ambulating a client with right-sided weakness, a nursing assistant should be positioned on which side of the client?

• A. Stands behind the client
• B. Positions the free hand on the client's shoulder
• C. Stands on the right side of the client
• D. Grasps the security belt in the midspine area of the small of the client's back

Correct answer: C

Rationale: When ambulating a client with right-sided weakness, the nursing assistant should stand on the affected side, which in this case is the client's right side. This position allows the assistant to provide proper support and assistance. Standing behind the client (Choice A) is incorrect as the assistant should be on the affected side. Positioning the free hand on the client's shoulder (Choice B) is a correct action as it helps in pulling the client toward them in case of a forward fall. Grasping the security belt in the midspine area of the small of the client's back (Choice D) is also correct to provide support and stability during ambulation.

4. Pulling is easier than pushing. So pulling a client rather than pushing them has which of the following advantages?

• A. reduces workload
• B. decreases opposition from gravity
• C. maintains stability
• D. prevents muscle strain

Correct answer: A

Rationale: When pulling a client, you work with the gravitational force instead of opposing it, which reduces the workload on your muscles. Choosing to pull a client minimizes the effort required compared to pushing. Choice B is incorrect because the force of gravity remains constant regardless of pushing or pulling. Choice C is irrelevant as stability is not directly related to the advantage of pulling over pushing. Choice D is inaccurate because pulling can still strain muscles if not executed correctly, but it generally reduces the overall workload in comparison to pushing.

5. A nurse is preparing for the admission of a client with pulmonary tuberculosis. Which action reflects the use of evidence-based practice in the care of the client?

• A. Keeping the door to the client's room closed
• B. Fitting the client for an N95 or HEPA (high-efficiency particulate air) mask to be worn at all times
• C. Placing the client in a semiprivate room with a cohort client
• D. Using a surgical mask when entering the client's room

Correct answer: A

Rationale: Evidence-based practice is an approach to client care that integrates the client's preferences, clinical expertise, and the best research evidence to deliver quality care. In the case of pulmonary tuberculosis, which is transmitted through the airborne route, keeping the door to the client's room closed is crucial to prevent the spread of infection. Placing the client in a semiprivate room with a cohort client is not recommended for airborne precautions; a private room is required to prevent transmission. Fitting the client for an N95 or HEPA mask is essential for the nurse's protection when entering the room, not for the client to wear at all times. Using a surgical mask when entering the client's room is not sufficient for airborne precautions; an N95 or HEPA mask is necessary.
