Nclex Questions Management of Care

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 is the 24-hour day-night cycle known as?

A. circadian rhythm
B. infradian rhythm
C. ultradian rhythm
D. non-REM rhythm

Correct answer: A

Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.

3. A nurse manager asks a nurse to work overtime because of a short-staffing problem. The nurse has made plans to do Christmas shopping after work and does not want to work overtime. What is the most assertive response by the nurse to her nurse manager?

A. "I'm not working overtime today."
B. "I have plans after work and will not be able to work overtime."
C. "You know how I hate to work overtime."
D. "I will if you need me, but I am not happy about this."

Correct answer: B

Rationale: The most assertive response in dealing with this conflict is the one that is direct and conveys a clear message in a positive manner. The nurse should assertively communicate her unavailability for overtime without being confrontational. Option A, "I'm not working overtime today," is too blunt and may come across as rude. Option C, "You know how I hate to work overtime," is not assertive but rather passive-aggressive. Option D, "I will if you need me, but I am not happy about this," is a passive-aggressive response as it implies compliance while expressing discontent. Option B, "I have plans after work and will not be able to work overtime," is the most appropriate response as it clearly states the nurse's unavailability without unnecessary aggression.

4. Who is responsible for obtaining the signature from the client on the informed consent?

A. the staff nurse
B. the charge nurse
C. the LPN
D. the physician

Correct answer: D

Rationale: The correct answer is the physician. It is the physician's responsibility to ensure that the client provides informed consent by obtaining their signature. While nurses play a crucial role in the healthcare team, their responsibility lies in verifying that the consent process has been completed correctly and advocating for the client. The staff nurse, charge nurse, and LPN do not have the authority to obtain the client's signature on the informed consent form, as this is within the scope of practice of the physician.

5. When a physician removes a chest tube, which type of dressing is recommended to be placed over the site?

A. transparent dressing
B. colloidal dressing
C. petrolatum gauze
D. nonadherent dressing

Correct answer: C

Rationale: Petrolatum gauze is recommended to be placed over the site when a physician removes a chest tube because it forms an airtight seal, helping prevent air from entering the pleural space. This airtight seal is crucial to avoid complications such as a pneumothorax. Transparent dressing is not ideal for this purpose as it may not provide a sufficient seal due to its design. Colloidal dressing and nonadherent dressing are also not suitable for chest tube removal sites as they do not offer the same level of protection against air leakage and may not provide the necessary sealing properties.
