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: C

Rationale: The correct answer is C: 'Nervousness and tremors.' In a client with hypothyroidism prescribed levothyroxine, the development of nervousness and tremors may indicate hyperthyroidism, which can result from excessive dosing of levothyroxine. Therefore, the nurse should promptly notify the healthcare provider to adjust the medication dosage. Choices A, B, and D are incorrect because weight gain, bradycardia, and fatigue are more commonly associated with hypothyroidism itself, indicating that the levothyroxine therapy may not be effective enough, rather than being signs of excessive dosing.

Correct Answer: D

Rationale: The best intervention when an elderly client is having trouble remembering to take their medications is to implement all of the above options. Setting up a pill organizer helps in organizing and remembering medication schedules. Involving family members in care ensures additional support and reminders. Arranging for a home health aide can provide direct assistance and supervision. Implementing all these strategies together can significantly improve medication adherence, especially in clients with memory issues. Each option plays a crucial role in addressing different aspects of the problem, making 'Implement all of the above' the most comprehensive and effective choice.

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.

Correct Answer: C

Rationale: The correct answer is C: Nervousness and tremors. These symptoms may indicate hyperthyroidism resulting from excessive dosing of levothyroxine. Weight gain (Choice A) is a common symptom of hypothyroidism and may indicate undertreatment or inadequate dosing. Bradycardia (Choice B) is a symptom of hypothyroidism and may improve with levothyroxine therapy; it does not typically indicate an urgent need for healthcare provider notification. Fatigue (Choice D) is a symptom of hypothyroidism and can persist even with levothyroxine treatment, so it is not a symptom that would require immediate notification of the healthcare provider.
