Correct Answer: A

Rationale: The correct answer is A because addiction cannot be accurately predicted. Choices B and C are incorrect. Withdrawal, drug tolerance, and physical dependence are not definitive signs of addiction, and pain medications can be used with patients who have a substance abuse history under careful monitoring. Choice D is incorrect because addiction is not solely signaled by deception and stockpiling; it is a complex condition with various behavioral, physical, and psychological aspects.

Correct Answer: B

Rationale: The correct answer is B: 'Coordinating patient care with other team members.' In a multidisciplinary healthcare team, nurses collaborate with other healthcare professionals to ensure comprehensive care for patients. Working independently without consulting others (choice A) is not aligned with the collaborative nature of multidisciplinary teams. Ignoring patient concerns (choice C) goes against the core principles of patient-centered care. Making all healthcare decisions alone (choice D) contradicts the teamwork approach of a multidisciplinary team.

Correct Answer: C

Rationale: The correct action for the nurse to take is to contact social services about the delivery of the oxygen equipment. This ensures that the necessary equipment is delivered to the client's home promptly. Choice A is incorrect because sending an oxygen tank from the facility is not a sustainable solution and may lead to legal and safety issues. Choice B is incorrect as contacting the insurance provider is not the appropriate course of action to address the delayed delivery. Choice D is also incorrect because notifying the provider about the delay may not directly lead to the timely delivery of the oxygen equipment.

Correct Answer: D

Rationale: The correct answer is to implement rounds every 2 hours during the day to offer toileting. This intervention helps prevent falls by addressing the common cause of unassisted mobility, which is the need to use the bathroom. Choice A is incorrect as restraints should not be the first choice for fall prevention due to the risk of injury and loss of independence. Choice B is incorrect because all side rails up can lead to entrapment and should only be used based on individualized assessments. Choice C may not be feasible for all residents over 85 years old and does not directly address the risk of falls.

Correct Answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.
