Correct Answer: B

Rationale: At the start of diastole, the ventricles relax and begin to fill with blood from the atria. As this relaxation phase begins, the pulmonic valve opens to allow blood to flow from the right ventricle to the pulmonary artery and then to the lungs for oxygenation. This marks the beginning of diastole, the period of the cardiac cycle when the heart is filling with blood. The closure of the tricuspid valve, closure of the aortic valve, and production of the first heart sound (S1) occur during systole, the phase of the cardiac cycle when the heart is contracting to pump blood out to the body.

Correct Answer: D

Rationale: The constellation of symptoms described in the scenario, including chronic constipation, fatigue, weight gain, irregular periods, cold intolerance, and delayed deep tendon reflexes, suggests hypothyroidism as the likely cause. Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones, leading to a slowdown in bodily functions. Constipation is a common symptom of hypothyroidism due to the decreased motility of the bowel. The presence of cold intolerance, weight gain, and irregular periods further supports this diagnosis, as these are classic symptoms of hypothyroidism. The delayed deep tendon reflexes, especially in the Achilles tendons, are indicative of the myopathic changes that can occur in hypothyroidism. It is important to further investigate thyroid function through laboratory testing to confirm the diagnosis and initiate appropriate treatment. Other conditions such as large bowel obstruction, irritable bowel syndrome, and rectal cancer are less likely based

Correct Answer: D

Rationale: Given the description provided, the lesion appears to be a dermatofibroma. Dermatofibromas are common benign skin lesions that typically present as a firm, solitary nodule on the skin. They commonly occur on the lower extremities but can also be found on the trunk. The characteristics of a dermatofibroma include being firm to the touch, having regular borders, being evenly pigmented, and a diameter typically less than 1 cm to 2 cm. They are usually painless and do not change significantly over time.

Correct Answer: C

Rationale: Given the patient's history and presentation, the most likely diagnosis for the abnormality seen on examination is a cervical polyp. Cervical polyps are benign growths that arise from the mucosal surface of the cervix. They are typically red or purple in color and can bleed easily, especially when touched, as in this case with the Pap smear causing bleeding. Cervical polyps are usually asymptomatic but can present with painless bleeding, particularly after intercourse. In this patient, the visualization of a red mass at the os during speculum examination and the finding of bleeding with manipulation support the diagnosis of a cervical polyp. Additionally, the absence of other significant findings on examination and the patient's overall healthy appearance further support this benign diagnosis. Further evaluation with possible removal of the polyp may be warranted for confirmation and to alleviate the bleeding symptoms.

Correct Answer: C

Rationale: The appropriate counsel for the patient during the visit would be to give information about the reduction of fat, cholesterol, and calories because he is concerned about his weight. This option addresses the patient's concern and provides guidance on making healthier choices to manage weight. Referring the patient to a nutritionist because he is anorexic (Option A) is not appropriate based on the information provided. Reassuring the patient that he has a normal body weight (Option B) may not address his concerns about weight. Giving the patient information about reducing fat and cholesterol only because he is obese (Option D) does not cover all aspects of a healthy diet such as managing calorie intake.
