Correct Answer: B

Rationale: The correct answer is B: Decreased fatigue and improved energy levels. Levothyroxine is a medication used to treat hypothyroidism by providing the body with the thyroid hormone it lacks. Therefore, a positive response to the medication would manifest as decreased fatigue and improved energy levels due to the correction of the thyroid hormone imbalance. Choices A, C, and D are incorrect because improved tolerance to cold, reduced anxiety, and increased sensitivity to heat are not direct indicators of the effectiveness of levothyroxine in managing hypothyroidism.

Correct Answer: D

Rationale: In this scenario, the patient's periorbital bruising and bloody drainage from both ears suggest a severe head injury. Projectile vomiting is a red flag symptom that may indicate increased intracranial pressure, which requires immediate attention to prevent further neurological deterioration. Rebound abdominal tenderness (choice A) typically indicates peritonitis and is not directly related to the primary head injury. Diminished breath sounds bilaterally (choice B) suggest a pneumothorax or hemothorax, which are important but not as immediately life-threatening in this context. Rib pain with deep inspiration (choice C) is concerning for rib fractures or pulmonary contusion, which are also important but do not take precedence over addressing the potential increased intracranial pressure.

Correct Answer: D

Rationale: Hyperemesis gravidarum, characterized by severe nausea and vomiting, leads to dehydration and electrolyte imbalances. The priority intervention is initiating IV fluids to correct these imbalances. Providing emotional support is important for the client's well-being, but addressing fluid and electrolyte imbalances takes precedence. Monitoring daily weight and encouraging small frequent meals are beneficial interventions but are not the priority when managing hyperemesis gravidarum.

Correct Answer: C

Rationale: A negative Pap smear does not rule out ovarian cancer, which often requires more comprehensive evaluation, including imaging studies or surgery. The client should be informed that the Pap smear primarily detects cervical cancer, not ovarian cancer. Therefore, further evaluation involving imaging studies or surgery may be necessary to determine the presence of ovarian cancer. Choice A is incorrect because a Pap smear is not sufficient to detect ovarian cancer. Choice B is incorrect because surgery may be necessary for further evaluation if ovarian cancer is suspected. Choice D is incorrect because further tests are needed to confirm or rule out ovarian cancer.

Correct Answer: C

Rationale: Correct Answer: Monitoring for signs of infection, such as fever or sore throat, is crucial when a client with rheumatoid arthritis is prescribed disease-modifying antirheumatic drugs (DMARDs). DMARDs can suppress the immune system, making individuals more susceptible to infections. Early detection of infections allows for prompt treatment and helps prevent complications. Choices A, B, and D are incorrect because while liver toxicity and gastrointestinal side effects are possible side effects of DMARDs, monitoring for signs of infection takes priority due to the increased risk of infections associated with these medications.
