Correct Answer: C

Rationale: When managing a patient with contact precautions, it is essential to dedicate all patient care equipment to that specific patient. This practice helps minimize the risk of spreading infections to other patients. Choice A, wearing protective gear for all patient interactions, is a general precaution but not specific to managing a patient with contact precautions. Choice B, ensuring visitors wear protective equipment, is important for infection control but not directly related to managing the patient with contact precautions. Choice D, disinfecting shared equipment before use, is a good practice for infection control in general but does not address the specific needs of a patient under contact precautions.

Correct Answer: C

Rationale: Measuring the calf circumference of both legs is crucial when assessing for DVT in an immobile patient. A significant increase in the circumference of one calf compared to the other suggests the presence of a deep vein thrombosis. Option A is incorrect because rubbing the lower leg may dislodge a clot if present. Option B is incorrect as elastic stockings should not be removed frequently as this can increase the risk of clot formation. Option D is incorrect as dorsiflexing the foot can lead to pain and should not be done to assess for DVT.

Correct Answer: B

Rationale: The correct first step for a healthcare professional who suspects a colleague of diverting narcotics is to report the suspicion to the supervisor. This action is essential to protect patient safety, uphold ethical standards, and comply with legal obligations. Confronting the colleague directly may not only escalate the situation but also jeopardize the investigation process. Ignoring the issue and continuing to work could potentially harm patients and violate professional responsibilities. Notifying the pharmacy, while important, should come after informing the appropriate supervisor or authority within the healthcare facility.

Correct Answer: B

Rationale: The correct first course of action for a nurse suspecting a colleague of diverting narcotics is to report the suspicion to the nurse manager. Confronting the colleague directly may not be safe and could compromise the investigation. Ignoring the situation is not appropriate as it can pose risks to patient safety. Keeping a record of the colleague's actions is not the primary action to take when drug diversion is suspected; reporting to the nurse manager is crucial for proper investigation and ensuring patient safety.

Correct Answer: B

Rationale: The most important action to ensure patient safety when administering a blood transfusion is to verify the patient's identity with two identifiers before starting the transfusion. This step is crucial to prevent transfusion errors, such as giving the blood to the wrong patient. Checking vital signs, ensuring timely administration, and confirming informed consent are also important aspects of blood transfusion safety but verifying the patient's identity is the highest priority to prevent errors.
