Correct Answer: D

Rationale: The correct answer is D: Clean hands thoroughly before and after patient contact. Hand hygiene is crucial for maintaining medical asepsis in a healthcare setting as it helps prevent the spread of infections between patients and healthcare workers. Choice A is incorrect because instruments should be sterilized regularly, not just when visibly contaminated. Choice B is incorrect as sterile gloves are not required for all patient interactions, only for specific procedures. Choice C is incorrect because patient areas should be disinfected regularly throughout the day, not just at the end of the day.

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: D

Rationale: When a healthcare provider prescribes a dose that is higher than normal, it is crucial for the nurse to contact the provider to clarify the prescription. Administering the prescribed dose without clarification can lead to potential harm to the patient due to the elevated dosage. Asking another nurse to verify the dose may not provide the necessary clarification from the prescriber. Administering only half of the prescribed dose without consulting the healthcare provider is not the appropriate action, as the full rationale behind the higher dose needs to be understood before any administration.

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: B

Rationale: The correct answer is B: Check for signs of infection. In skeletal traction, the priority action for the nurse when a client complains of pain in the leg is to first assess for signs of infection. Pain in skeletal traction can be a symptom of infection or other complications, so checking for signs of infection is crucial before considering other interventions. Increasing pain medication immediately (Choice A) may mask the symptoms of an underlying infection. Repositioning the client's leg for comfort (Choice C) may provide temporary relief but does not address the potential underlying issue. Notifying the physician of the client's complaints (Choice D) is important but assessing for infection should come first to ensure timely and appropriate intervention.
