Correct Answer: C

Rationale: The correct understanding of standard precautions includes wearing appropriate personal protective equipment to prevent exposure to body fluids. Wearing eyewear when emptying the urinary drainage bag is crucial as it protects the nurse's eyes from potential splashes of body fluids. Teaching the patient about good nutrition (Choice A) is important for overall health but is not directly related to standard precautions. Disposing of an uncapped needle correctly (Choice B) is part of safe needle handling but does not specifically relate to standard precautions. Donning gloves when wearing artificial nails (Choice D) is not a correct understanding of standard precautions, as artificial nails can harbor microorganisms and increase the risk of infection transmission.

Correct Answer: D

Rationale: The correct first action for the nurse to take in this situation is to file an incident report immediately. By doing so, the nurse ensures that the unsafe practice is documented for further investigation and corrective action. Speaking to the colleague directly may not address the root cause of the issue and could lead to potential conflicts. Ignoring the situation is not an appropriate response as it compromises patient safety. Reporting the colleague to the nursing manager should be done after filing an incident report to ensure that appropriate actions are taken to prevent future occurrences of non-compliance with hand hygiene protocols.

Correct Answer: B

Rationale: In the case of a client with unstable blood pressure, the priority action for the nurse is to continuously monitor the client's vital signs. This allows for immediate detection of any fluctuations in blood pressure and timely intervention if necessary. Choice A, monitoring every two hours, may not provide real-time information needed for prompt intervention. Choices C and D suggest waiting for instructions from the healthcare provider, which could cause a delay in addressing the unstable blood pressure, potentially leading to adverse outcomes. Therefore, the most appropriate initial action is to continuously monitor the client's vital signs.

Correct Answer: B

Rationale: The presence of chronic illness is the factor that places a patient at the highest risk for infection. Chronic illness can compromise the immune system's ability to fight off infections effectively, making individuals more susceptible to getting sick. Option A, a healthy immune system, actually reduces the risk of infection. Option C, being well-nourished, can support overall health but does not directly correlate with infection risk. While age over 65 years is a risk factor for certain infections due to age-related immune system changes, chronic illness has a more significant impact on infection risk.

Correct Answer: B

Rationale: The correct answer is B: Providing wigs and other coping resources helps clients manage the emotional effects of chemotherapy-related hair loss. Encouraging the client to cut their hair short before chemotherapy (Choice A) is not necessary as hair loss may still occur. Assuring the client that hair loss will be minimal (Choice C) may provide false hope as hair loss is a common side effect of chemotherapy. Offering medication to reduce hair loss (Choice D) is not a typical approach as chemotherapy-related hair loss is often an expected side effect that cannot be entirely prevented with medication.
