Correct Answer: A

Rationale: The correct answer is to check the client's respiratory rate. Morphine can lead to respiratory depression, which makes it crucial for the nurse to monitor the client's breathing closely. Assessing the respiratory rate helps in early detection of potential respiratory depression and allows prompt intervention. While assessing pain level (choice B) is important, monitoring the respiratory status takes precedence due to the risk of respiratory depression with morphine. Monitoring blood pressure (choice C) is relevant but not as crucial as assessing respiratory status in a client receiving morphine. Evaluating the level of consciousness (choice D) is also important but does not directly address the immediate risk associated with morphine administration.

Correct Answer: B

Rationale: The correct answer is 'B. Hyponatremia.' Hydrochlorothiazide can lead to electrolyte imbalances, such as hyponatremia, due to its diuretic effect. This potential adverse effect should be closely monitored in patients taking HCTZ. Choice A, hyperkalemia, is less likely to occur with HCTZ as it tends to cause hypokalemia. Choice C, bradycardia, is not a common adverse effect of HCTZ. Choice D, hyperglycemia, is also less commonly associated with HCTZ use compared to hyponatremia.

Correct Answer: D

Rationale: Sudden onset of severe abdominal pain may indicate complications such as peritonitis, bowel perforation, or internal bleeding. These conditions are serious and require immediate medical attention to prevent further complications or deterioration. Absence of bowel sounds, mild abdominal distention, and drainage of serosanguineous fluid are common findings after abdominal surgery and may not necessarily indicate an emergency situation requiring immediate reporting to the healthcare provider. Severe abdominal pain post-surgery should always be reported promptly as it could signify a life-threatening situation that needs urgent evaluation and intervention.

Correct Answer: A

Rationale: The most important instruction for a client with a history of seizures being discharged home is to take their medication as prescribed. Consistent and timely intake of anti-seizure medication is vital in managing seizures and preventing episodes. While instructions like avoiding driving until the condition is stable, keeping a seizure diary, and avoiding alcohol consumption are important, none are as critical as ensuring proper medication adherence to control seizures effectively. Failure to take prescribed medications can lead to breakthrough seizures, compromising the patient's safety and seizure control.

Correct Answer: C

Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.
