Correct Answer: C

Rationale: The appropriate action when a client is wearing a necklace before surgery is to ask the patient for permission to lock it in a safe. This is in line with hospital policy to secure valuables before entering surgery. Choice A is incorrect because simply placing the necklace in a drawer may not be secure. Choice B is incorrect as taping the necklace to the patient's skin can cause skin irritation and is not a standard practice. Choice D is incorrect because the responsibility for securing valuables typically lies with the healthcare team, not the patient's family.

Correct Answer: B

Rationale: The best course of action is to ask the client for permission to secure the jewelry. This respects the client's religious beliefs while also ensuring that the jewelry does not interfere during the surgical procedure. Proceeding with surgery without addressing the presence of the jewelry can lead to complications or distress for the client. Removing the jewelry without consent or postponing the surgery solely due to the presence of religious jewelry are not appropriate actions in this situation.

Correct Answer: B

Rationale: Tachycardia and low blood pressure are indicative of worsening dehydration in a patient. Tachycardia is the body's compensatory mechanism to maintain cardiac output in response to decreased intravascular volume, while low blood pressure reflects inadequate perfusion due to decreased fluid levels. Bradycardia and shallow respirations are not typical findings in worsening dehydration, and clear lung sounds do not directly correlate with the severity of dehydration.

Correct Answer: B

Rationale: When a nurse discovers a discrepancy in the narcotics log, the appropriate next step is to report the discrepancy to the nurse manager. This is important to ensure that the issue is properly investigated and addressed. Choice A is incorrect because simply correcting the log and notifying the pharmacy may not address the root cause of the discrepancy. Choice C is incorrect as re-administering the narcotic without clarification could lead to potential harm or legal issues. Choice D is incorrect as disposing of the narcotic without following proper protocols and documentation could result in further complications.

Correct Answer: A

Rationale: The correct answer is A: Perform hand hygiene before and after patient contact. Effective hand hygiene is a fundamental infection control measure that helps prevent the spread of pathogens. Wearing gloves when administering medications (choice B) is important for protecting both the patient and the nurse but is not a direct demonstration of infection control. Disposing of used equipment in designated containers (choice C) is more related to proper waste management than infection control. Wearing a mask when interacting with the patient (choice D) is essential in certain situations, but hand hygiene is a more universal and critical practice for infection control.
