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.' A specific test correctly identifies individuals who do not have a particular disease. In this case, since the lab culture report is negative for the suspected infection, it means the test is good at ruling out the disease. 'Sensitive' (choice B) would be incorrect as sensitivity refers to a test's ability to correctly identify individuals who do have the disease. 'Negative culture' (choice C) is incorrect as it describes the result rather than the test's characteristic. 'Marginal finding' (choice D) is unrelated to the concept of correctly identifying individuals without the disease.

2. Hearing screening of prematurely born infants is an effective means of identifying disease and is an example of:

• A. Primary prevention.
• B. Secondary prevention.
• C. Tertiary prevention.
• D. Disability prevention.

Correct answer: B

Rationale: The correct answer is B: Secondary prevention. Hearing screening for prematurely born infants falls under secondary prevention, which aims to identify and treat a condition in its early stages to prevent further complications. Primary prevention (choice A) focuses on preventing the disease from occurring, while tertiary prevention (choice C) involves managing complications and preventing disability. Choice D, disability prevention, is not a recognized category of prevention. In this context, the screening helps in early identification of hearing loss, allowing for timely intervention to prevent further impairment or complications, aligning with the principles of secondary prevention.

3. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?

• A. serotonin
• B. cortisol
• C. alcohol
• D. narcotics

Correct answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.

4. 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.

5. When placing a Foley catheter in a female client, what is the correct order of steps?

• A. E, A, F, B, C, G, D
• B. A, E, B, F, G, D, C
• C. A, E, F, B, C, G, D
• D. E, A, F, B, C, G, D

Correct answer: D

Rationale: The correct order for placing a Foley catheter in a female client is as follows: E. Place the client in a supine position with flexed knees, A. Prepare the sterile field, F. Place lubricant on the catheter, B. Separate labia with the non-dominant hand, C. Clean the urinary meatus using cleansing solutions and forceps, G. Place the catheter in the meatus with the dominant (sterile) hand, and D. Inflate the catheter balloon. This sequence ensures proper hygiene, patient comfort, and reduces the risk of infection. Incorrect sequences could compromise sterility, cause discomfort, and increase the risk of infection. Therefore, the correct answer is E, A, F, B, C, G, D.
