You are working in a college health clinic and seeing a young woman with a red, painful, swollen DIP joint on the left index finger. There are also a few papules, pustules, and vesicles on reddened bases, located on the distal extremities. This would be consistent with which of the following?

Correct Answer: D

Rationale: The description provided indicates a presentation consistent with gonococcal arthritis. Gonococcal arthritis is an infectious arthritis caused by the bacteria Neisseria gonorrhoeae. Symptoms typically include red, swollen, and painful joints, especially affecting the distal joints of the limbs. The presence of papules, pustules, and vesicles on reddened bases at the distal extremities is characteristic of disseminated gonococcal infection. In women, the DIP joint involvement in the finger can be indicative of this condition. Prompt diagnosis and treatment with antibiotics are essential to prevent complications associated with gonococcal arthritis. It is important to consider a sexually transmitted infection like gonorrhea in young patients presenting with joint symptoms and cutaneous findings.

Correct Answer: D

Rationale: The closed fist gesture over the sternum to describe chest pain is a typical characteristic of angina pectoris. Angina pectoris is chest pain or discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood. The gesture of clenching a fist over the sternum is often used to describe the tight, squeezing, or pressure-like discomfort experienced with angina. This type of chest pain is typically triggered by physical or emotional stress and is relieved by rest or medications like nitroglycerin. Considering the patient's age, smoking history, and the description of the chest pain gesture, angina pectoris should be a top consideration in this case.

Correct Answer: C

Rationale: In the context of visual acuity, the numbers in the ratio 20/100 represent a comparison between the patient's vision and normal vision. Specifically, a visual acuity of 20/100 means that the patient can see at 20 feet what a person with normal vision can see at 100 feet. This indicates that the patient's vision is reduced, as she needs to be closer to see the same level of detail compared to someone with normal vision.

Correct Answer: B

Rationale: The patient described is most likely suffering from an external hemorrhoid. External hemorrhoids are swollen veins located near the opening of the anus, often resulting from increased pressure in the rectal area. The presence of a swollen bluish ovoid mass containing a blood clot is characteristic of an external hemorrhoid. The pain experienced during digital rectal examination further supports this diagnosis, as external hemorrhoids are typically painful when touched. In this case, there are no palpable masses within the anus or rectum, ruling out anorectal cancer or internal hemorrhoids. Anal fissures are small tears in the lining of the anus, which would present differently from the described swollen mass with a blood clot.

Correct Answer: C

Rationale: The right ventricle is the only chamber of the heart that can be assessed by palpation during a cardiac examination. The right ventricle is located close to the sternum on the anterior chest wall, making it accessible for palpation. By palpating the area near the lower left sternal border, just beside the sternum, a healthcare provider can assess the size and function of the right ventricle. It is important to note that the other chambers of the heart (left atrium and right atrium) are not typically assessed by palpation due to their deeper location within the chest cavity. The sinus node, which is responsible for generating the heart's electrical impulses, is also not directly palpable during a cardiac examination.

Correct Answer: D

Rationale: Prostate cancer is more prevalent in certain ethnic groups, with African-American men having the highest risk of developing prostate cancer compared to men of other ethnicities. Additionally, men of Caribbean and West African descent also have an increased risk compared to men of Asian descent. This indicates that ethnicity plays a role in the risk of developing prostate cancer.

Correct Answer: B

Rationale: Leaning forward in the upright position increases venous return and systemic vascular resistance, which can help accentuate the intensity of aortic regurgitation murmur. This position helps to bring the heart closer to the chest wall, making the murmur easier to auscultate and potentially increasing its intensity.

Correct Answer: C

Rationale: Pain in the calf is a common symptom of atherosclerosis in the lower extremities, also known as peripheral artery disease (PAD). Atherosclerosis is the buildup of plaque in the arteries, leading to reduced blood flow. The calf pain associated with PAD is often described as cramping, aching, or fatigue that occurs during walking and is relieved with rest. This is called intermittent claudication. Thigh, knee, and ankle pain could have other causes, but calf pain specifically raises concerns for atherosclerosis in the lower extremities.
