Correct Answer: A

Rationale: Prolonged bed rest can lead to hypocalcemia due to decreased mobility and bone resorption. In this scenario, the low serum calcium level of 4.0 mg/dL is likely a result of decreased bone activity and calcium release due to prolonged bed rest. Renal insufficiency would more likely lead to hypercalcemia due to impaired excretion of calcium by the kidneys. Hyperparathyroidism is characterized by increased calcium levels as a result of excess parathyroid hormone. Excessive ingestion of vitamin D can cause hypercalcemia by increasing intestinal absorption of calcium.

Correct Answer: D

Rationale: Somogyi effect, also known as rebound hyperglycemia, occurs as a response to nighttime hypoglycemia. Eating a protein and carbohydrate snack at bedtime can help prevent this by stabilizing blood sugar levels throughout the night. Instructing the client to take insulin at 2:00 PM each day (Choice A) may not directly address the nighttime hypoglycemia concern. Engaging in physical activity daily (Choice B) is generally beneficial for diabetes management but may not specifically prevent Somogyi's effect. Increasing the dose of regular insulin (Choice C) without addressing the nighttime hypoglycemia issue can exacerbate the problem.

Correct Answer: B

Rationale: The primary goal of public health is to improve the health of populations by focusing on prevention, health promotion, and addressing the social determinants of health. Choice A is incorrect because public health looks at health from a population perspective rather than focusing on individual patient care. Choice C, while a potential benefit, is not the primary goal of public health. Choice D is incorrect as increasing hospital admissions is not a goal of public health; in fact, public health aims to prevent unnecessary hospitalizations through preventive measures.

Correct Answer: A

Rationale: The correct answer is to report the infection to the local health department. Chlamydia is a reportable disease, meaning healthcare providers are required to report cases to public health authorities for tracking and control measures. Choice B is incorrect because chlamydia is a bacterial infection, not a viral infection, so antiviral cream would not be effective. Choice C is important advice for preventing the spread of chlamydia but is not the priority in this scenario. Choice D is not necessary for chlamydia, as it is primarily transmitted through sexual contact.

Correct Answer: D

Rationale: The signs and symptoms described point towards rheumatoid arthritis. Erythema marginatum, Sydenham chorea, epistaxis, abdominal pain, fever, cardiac issues, and skin nodules are classic manifestations of rheumatic fever, which is a complication of untreated streptococcal infection. This condition can lead to rheumatoid arthritis over time. Choices A, B, and C are incorrect as they do not align with the provided signs and symptoms, and they are not associated with the clinical presentation described.
