Correct Answer: C

Rationale: The description of the patient's left shoulder pain, with a sharp catching pain and a sensation of something grating during overhead movements, in addition to tenderness just below the tip of the acromion in the area of tendon insertions, is suggestive of calcific tendinitis. Calcific tendinitis occurs when calcium deposits form within a tendon, most commonly affecting the rotator cuff tendons. This condition can cause pain, tenderness, and limited range of motion, particularly with certain movements like overhead reaching. The negative drop arm test, lack of limitation with shoulder shrug, absence of tenderness to palpation in the bicipital groove, and the patient not holding his arm close to his side help differentiate calcific tendinitis from other shoulder pathologies like rotator cuff tendinitis, rotator cuff tear, and bicipital tendinitis.

Correct Answer: A

Rationale: The point of maximal impulse (PMI), also known as the apical impulse, is the point where the left ventricle is closest to the chest wall. Normally, the PMI is located in the left 5th intercostal space, around 7 to 9 cm lateral to the sternum. This area corresponds to the apex of the heart. By palpating the PMI, healthcare providers can assess the size, strength, and regularity of the heart's contractions, which can provide important diagnostic information about cardiac health. Locating the PMI accurately is essential for physical examination and diagnosis of cardiac conditions.

Correct Answer: D

Rationale: The most appropriate response based on the information provided would be to give the patient information concerning the reduction of fat and cholesterol in her diet because she is obese. The patient's weight falls in the obese category, and addressing diet is an important step in managing obesity. Providing guidance on reducing fat and cholesterol intake can help the patient make healthier food choices and work towards achieving a healthier weight. Additionally, diet plays a significant role in overall health, so addressing nutrition is crucial when managing obesity. It is important to approach the topic sensitively and provide support and resources to help the patient make positive changes for their health.

Correct Answer: C

Rationale: A "red flag" regarding patients presenting with a headache is their age being over 50. This is because new-onset or persistent headaches in individuals over 50 may raise concerns about underlying serious conditions such as temporal arteritis, brain tumor, or other vascular issues. It is important to thoroughly evaluate and consider these possibilities in older patients with headaches to ensure appropriate management and timely intervention.

Correct Answer: C

Rationale: The presentation of multiple small, blood-red, raised lesions over the anterior chest and abdomen in a middle-aged man raises concern for a condition known as cherry angiomas. Cherry angiomas are common benign vascular growths often seen in middle-aged and older individuals. They are typically asymptomatic and do not require treatment unless they are bothersome to the patient cosmetically.
