Correct Answer: B

Rationale: While it is important to ask about recent sexual activity and whether it included sexual intercourse, using the term "intimate physical contact" is not specific enough. This question could potentially lead to misinterpretation or confusion regarding what types of activities are being referred to. It is more appropriate to directly ask about sexual intercourse when obtaining a sexual history. The other options are all appropriate questions to elicit information about the patient's sexual history.

Correct Answer: A

Rationale: A sudden, painless unilateral vision loss may be caused by a retinal detachment. Retinal detachment occurs when the retina, which is the light-sensitive tissue lining the back of the eye, pulls away from its normal position. This can lead to visual disturbances, including sudden loss of vision in one eye. Retinal detachment can be a medical emergency and requires prompt evaluation and treatment to prevent permanent vision loss. Other conditions mentioned in the choices, such as corneal ulcer, acute glaucoma, and uveitis, may also cause vision problems but are less likely to present with a sudden and painless unilateral vision loss as a primary symptom.

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: B

Rationale: The patient's presentation with an enlarged chest diameter, decreased breath sounds throughout all lobes, and the presence of rhonchi over all lung fields is suggestive of a chronic condition that affects the entire respiratory system. These findings are classic for COPD, a progressive lung disease characterized by airflow limitation. The breath sounds are decreased due to airflow obstruction, and the presence of rhonchi indicates mucus production and airway inflammation commonly seen in COPD. In contrast, a spontaneous pneumothorax would typically present with sudden chest pain and shortness of breath, often in a younger patient with risk factors such as smoking. Asthma would present with wheezing, shortness of breath, and possibly a history of atopy or allergies. Pneumonia would typically present with fever, cough, and focal findings on chest examination, such as crackles or bronchial breath sounds over a consolidated area. In
