Correct Answer: B

Rationale: The correct instruction the nurse should include is to 'Rest as needed throughout the day.' Fatigue is a common symptom of multiple sclerosis (MS), and adequate rest is essential to manage it effectively. Resting as needed helps conserve energy and prevent fatigue from worsening. Choices A, C, and D are incorrect. 'Exercise to the point of exhaustion' is not recommended as it can lead to increased fatigue. 'Avoiding physical activity' entirely is not advisable as appropriate exercise can help maintain strength and energy levels. 'Exercising only once per week' may not be sufficient to combat fatigue and maintain overall well-being in clients with MS.

Correct Answer: B

Rationale: The correct answer is B: RN. An RN is required for managing post-surgical care in the immediate postoperative period, especially for a client following thoracic surgery. The RN is equipped with the necessary knowledge and skills to assess the client's condition, provide complex care, and recognize and respond to any complications that may arise. Assigning the client to the Charge nurse (A) may not be appropriate as the Charge nurse focuses more on administrative and managerial tasks rather than direct patient care. LVNs (C) and APs (D) may have limitations in their scope of practice when it comes to managing post-surgical care following thoracic surgery, which requires a higher level of assessment and intervention that an RN can provide.

Correct Answer: C

Rationale: The correct answer is C: Agitation and assaultiveness. Risperidone is commonly prescribed for clients with Alzheimer's disease to reduce symptoms of agitation and aggressive behavior. This medication helps in managing challenging behaviors often seen in individuals with Alzheimer's. Choice A, sleep disturbances, is incorrect as risperidone is not primarily indicated for treating sleep issues in Alzheimer's patients. Choice B, concomitant depression, is also incorrect as risperidone is not the first-line treatment for depression in Alzheimer's disease. Choice D, confusion and withdrawal, is incorrect as risperidone does not directly target these symptoms in Alzheimer's patients.

Correct Answer: A

Rationale: The correct answer is A: Chest pain radiating to the arm and shortness of breath. These are classic signs of an acute myocardial infarction. Choice B is incorrect because nausea, vomiting, and high fever are not typical signs of a heart attack. Choice C is incorrect as headache, confusion, and low blood pressure are not specific to myocardial infarction. Choice D is incorrect because an acute myocardial infarction typically presents with an increased heart rate, not bradycardia.

Correct Answer: A

Rationale: The correct answer is A: Lamb. Lamb is high in saturated fat, which is linked to an increased risk of developing cancer. Choice B (Poultry) is a lean protein source and is not associated with an increased cancer risk. Choice C (Tuna) is a good source of omega-3 fatty acids, which have anti-inflammatory properties that may reduce cancer risk. Choice D (Beef) is also high in saturated fat like lamb, making it a poor choice for cancer prevention.
