Correct Answer: B

Rationale: The description of dark tan patches with a reddish cast that have sharp borders and fine scales, especially more prominent on the upper back, chest, neck, and upper arms, is classic for tinea versicolor. Tinea versicolor is a superficial fungal infection caused by Malassezia species, which commonly affects individuals who sweat more, such as those working outdoors like the construction worker in this case. The rash is often pruritic (itchy) and can vary in color from tan to pink or red. The fine scales on the patches are a result of the accumulation of the yeast in the affected areas.

Correct Answer: C

Rationale: The most likely cause of neck pain in this scenario is a cervical sprain. A cervical sprain is an injury to the ligaments in the neck as a result of sudden force or trauma, such as a motor vehicle collision. The symptoms of a cervical sprain typically include pain, stiffness in the neck, and muscle spasm. The fact that the patient has pain and spasm over the paraspinous muscles on one side of the neck, along with pain during active range of motion, is characteristic of a sprain. It is important to consider this diagnosis in individuals who have recently experienced trauma to the neck region. Treatment for a cervical sprain usually includes pain management, rest, and gentle stretching exercises to help with recovery.

Correct Answer: D

Rationale: The scenario described with a strong pulse followed by a weak pulse is characteristic of pulsus paradoxus, a finding often associated with cardiac tamponade. Cardiac tamponade is a medical emergency where there is an accumulation of fluid (such as blood) in the pericardial sac that exerts pressure on the heart, limiting its ability to pump effectively. As a result, patients may exhibit this pulsus paradoxus, where the pulse strength varies with respiration. The other conditions listed (emphysema, asthma exacerbation, severe left heart failure) are not typically associated with this specific pulsatile pattern.

Correct Answer: D

Rationale: A subconjunctival hemorrhage is a common and benign condition characterized by blood in the space between the conjunctiva and sclera of the eye. The condition often presents as a painless, sharply demarcated area of redness on the white part of the eye, typically without associated discharge or visual disturbances. In this case, the absence of eye pain, discharge, visual disturbances, and clear cornea make subconjunctival hemorrhage the most likely diagnosis. The history of forceful coughing with a recent cold is also consistent with the increased intraocular pressure leading to a rupture of a small blood vessel, resulting in the hemorrhage. Treatment is not usually required as the condition is self-limiting and resolves on its own over time.

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.
