Correct Answer: B

Rationale: The correct answer is B: Increased wheezing and shortness of breath. During an asthma exacerbation, bronchial airways become inflamed and narrowed, leading to increased wheezing and shortness of breath. This is a classic sign of worsening asthma. Other choices are incorrect because: A) Decreased work of breathing is not expected in an asthma exacerbation as the patient usually struggles to breathe. C) Improved oxygen saturation is unlikely as airway obstruction can lead to decreased oxygen levels. D) Decreased sputum production is not a typical sign of asthma exacerbation; in fact, increased sputum production may occur due to airway inflammation.

Correct Answer: B

Rationale: The correct answer is B: Hypothyroidism. In this case, the patient's symptoms of fatigue, weight gain, cold intolerance, dry skin, and slow heart rate are indicative of hypothyroidism. The thyroid gland is underactive, leading to decreased production of thyroid hormones, which regulate metabolism. These symptoms align with the typical clinical presentation of hypothyroidism. Other choices are incorrect because hyperthyroidism (choice A) would present with symptoms like weight loss, heat intolerance, and a fast heart rate. Cushing's syndrome (choice C) and Addison's disease (choice D) are both conditions related to the adrenal glands and would have different symptom presentations compared to what is described in the case scenario.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Regular blood glucose monitoring helps in understanding patterns and making informed decisions. 2. Adjusting insulin based on blood glucose levels is crucial for effective diabetes management. 3. This statement shows the patient's understanding of the need for personalized insulin adjustments. 4. It promotes self-management and proactive approach to blood sugar control. Summary: B: Stopping insulin abruptly can lead to dangerous complications. C: Skipping meals can disrupt blood sugar levels and is not recommended. D: Waiting for high blood sugar to use insulin can result in uncontrolled levels and complications.

Correct Answer: A

Rationale: The correct answer is A: Limiting sodium intake. This is crucial for a patient with hypertension as excess sodium can lead to increased blood pressure. Sodium intake should be limited to lower the risk of cardiovascular complications. B: Increasing potassium intake is beneficial, but not as critical as limiting sodium for hypertension management. C: Increasing fluid intake may or may not be necessary depending on the patient's condition, but it is not as crucial as limiting sodium for hypertension management. D: Consuming more caffeine can actually elevate blood pressure, so it is not recommended for patients with hypertension.

Correct Answer: C

Rationale: The correct answer is C: Linea nigra. This is a common finding during pregnancy due to hormonal changes causing hyperpigmentation on the abdomen. The other choices are incorrect because keratosis refers to a skin condition characterized by rough, scaly patches; melasma is a condition causing dark patches on the skin, often due to hormonal changes; and linea gravida is not a recognized term in dermatology. Therefore, based on the context of the patient being pregnant and presenting with hyperpigmentation on her face, the most likely finding would be Linea nigra, a dark line that runs from the navel to the pubic bone during pregnancy.
