Correct Answer: B

Rationale: The correct answer is to apply a yellow fall risk bracelet to the patient. This action helps alert staff to the patient's increased risk of falling, prompting them to implement appropriate safety measures and precautions. Placing the call light within reach (choice A) is generally important but does not specifically address fall risk. Assisting the patient when ambulating (choice C) is important but may not be sufficient alone to prevent falls. Ensuring the patient's room is well-lit (choice D) is also crucial for patient safety but does not directly address the patient's fall risk status.

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: 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: B

Rationale: The most appropriate response for the nurse when a client asks about a medication is to refer the client to the healthcare provider for more information. This ensures that the client receives accurate and detailed information from the appropriate source. Providing detailed information or a brief explanation as choices A and C suggest may not be within the nurse's scope of practice and could potentially lead to misinformation or confusion. Asking another nurse to explain the medication, as in choice D, may not guarantee accurate information, so it is best to involve the healthcare provider directly.

Correct Answer: D

Rationale: Crackles heard in the lung bases are most concerning in a patient with pneumonia as they suggest fluid accumulation in the lungs, indicating possible severe infection or respiratory distress. Prompt intervention is required to prevent further complications.\n\nChoice A, fever of 101°F, is common in infections like pneumonia but may not be as immediately concerning as crackles indicating fluid in the lungs.\n\nChoice B, a blood pressure of 140/90 mmHg, is within normal limits and not directly indicative of pneumonia severity.\n\nChoice C, a heart rate of 95 beats per minute, is slightly elevated but not as critical as crackles suggesting fluid in the lungs.
