Correct Answer: C

Rationale: Discussing patient information in public areas where others may overhear is considered a breach of patient confidentiality because it compromises the privacy and confidentiality of the patient's health information. Choices A and D are not breaches of confidentiality as discussing patient information with other healthcare providers in a private setting or in a private, secure setting with those involved in the patient's care is appropriate. Choice B is also incorrect as sharing patient information with family members without the patient's consent could potentially be a breach of privacy but is not the best answer in this context.

Correct Answer: C

Rationale: The correct answer is to monitor blood glucose before meals and at bedtime. This timing allows the client to assess fasting levels and make informed decisions about mealtime insulin or medication doses. Monitoring only when feeling unwell (choice A) is not sufficient for proper glucose management as it may miss important trends. Monitoring only before meals (choice B) is helpful but does not provide a complete picture of the client's glucose control throughout the day. Monitoring only after meals (choice D) is less beneficial than monitoring before meals as it does not capture fasting levels. Therefore, monitoring before meals and at bedtime (choice C) is the most comprehensive approach to maintain good glucose control and prevent complications.

Correct Answer: C

Rationale: The correct answer is to take levothyroxine on an empty stomach in the morning. This instruction is essential to enhance absorption and efficacy of the medication. Taking levothyroxine with meals, at bedtime, or with a glass of milk can interfere with its absorption and effectiveness, leading to suboptimal treatment outcomes.

Correct Answer: C

Rationale: The correct answer is C. Regular insulin typically has an onset of action within 30 minutes and peaks 2-4 hours after administration. Given that the insulin was administered at 2 p.m., the onset of action can be expected around 2:30 p.m., and the peak effect would occur between 4-6 p.m. Choice A is incorrect as the onset and peak are too close together for regular insulin. Choice B is incorrect because the onset time is too soon after administration. Choice D is incorrect as the onset time is too delayed for regular insulin.

Correct Answer: A

Rationale: Primary hyperaldosteronism is characterized by excessive secretion of aldosterone from the adrenal cortex. Aldosterone, a hormone produced by the adrenal cortex, plays a crucial role in regulating blood pressure by promoting sodium and water retention in the kidneys. The adrenal medulla secretes catecholamines like epinephrine and norepinephrine, which are involved in the 'fight or flight' response, not in regulating blood pressure. The pancreas secretes insulin and glucagon, hormones involved in blood sugar regulation, not blood pressure. The parathyroid glands regulate calcium levels in the blood, not blood pressure.
