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: Encouraging oral fluid intake is a crucial nursing intervention in managing a patient with fluid volume deficit. By encouraging oral fluid intake, the patient can increase hydration levels, helping to correct the deficit. Administering IV fluids may be necessary in severe cases or when the patient is unable to tolerate oral intake. Monitoring urine output and checking electrolyte levels are essential aspects of assessing fluid volume status, but they are not direct interventions for correcting fluid volume deficit. Monitoring skin turgor and capillary refill are important assessments for fluid volume status but are not direct management strategies.

Correct Answer: B

Rationale: The correct intervention for a client with COPD is to encourage pursed-lip breathing. Pursed-lip breathing helps improve oxygenation by preventing airway collapse, slowing down the breathing rate, and promoting better gas exchange. Administering oxygen at 2L/min via nasal cannula is not the first-line intervention as it can cause oxygen toxicity in COPD patients. Positioning the client in high Fowler's position may improve ventilation but does not specifically address the breathing technique required for COPD. Encouraging deep breathing and coughing is generally not recommended for clients with COPD as it can lead to air trapping and increased work of breathing.

Correct Answer: B

Rationale: Increasing dietary fiber is an effective recommendation for clients experiencing constipation as it helps promote regular bowel movements. Choice A, increasing fluid intake, is also important but the most appropriate initial recommendation for constipation is to increase dietary fiber. Choice C, administering a laxative, should not be the first-line recommendation and is typically considered after dietary and lifestyle interventions. Choice D, encouraging bed rest, does not directly address constipation relief or prevention.

Correct Answer: D

Rationale: The key management strategy for diabetic ketoacidosis (DKA) involves a comprehensive approach that includes administering insulin to lower blood glucose levels, monitoring blood glucose levels to ensure they are within the target range, and administering IV fluids to correct dehydration and electrolyte imbalances. Choosing 'All of the above' as the correct answer is the most appropriate because all three interventions are essential components of DKA management. Administering insulin alone without addressing fluid status and monitoring blood glucose could lead to complications. Similarly, solely focusing on IV fluids or blood glucose monitoring without insulin administration would not effectively manage DKA.
