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: 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: C

Rationale: The correct answer is C, 'Battery.' Administering the injection without the client's consent constitutes battery. Assault involves the threat of harm, not the actual act. False imprisonment is restraining a client against their will, which does not apply here. Libel refers to a false written statement, which is not relevant in this scenario.

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: B

Rationale: The correct answer is B. A bivalve cast can help decrease the risk of compartment syndrome by providing space for swelling, thus preventing the build-up of pressure within the muscles. Choices A, C, and D are incorrect because they are not directly related to preventing compartment syndrome. Choice A is more focused on managing heart failure, choice C on reducing intracranial pressure, and choice D on restoring intrathoracic pressure after a pneumothorax, which are not relevant to preventing compartment syndrome.
