On auscultation her lung fields have normal breath sounds with no rhonchi, wheezes, or crackles. Percussion and palpation are unremarkable. Auscultation of the heart has an S and S 1 2 with no S or S . A scratching noise is heard at the lower left sternal border, coincident with 3 4 systole; leaning forward relieves some of her pain. She is nontender with palpation of the chest wall. What disorder of the chest best describes this disorder?

Correct Answer: B

Rationale: The clinical presentation described involves a patient with pericarditis. Pericarditis is inflammation of the pericardium, the sac surrounding the heart, which can lead to characteristic findings such as a scratching noise heard on auscultation, leaning forward relieving pain, and normal lung examination findings. The presence of pericarditis can also lead to a pericardial friction rub, which is often described as a scratching or grating sound heard best at the lower left sternal border.

Correct Answer: B

Rationale: A varicocele is a common cause of a "bag of worms" feeling in the scrotum. It occurs due to the dilation of the veins within the spermatic cord, leading to a palpable mass above the testicle. Varicoceles are more commonly found on the left side due to the anatomy of the left testicular vein, which drains into the left renal vein at a right angle, making it more susceptible to increased pressure and dilation.

Correct Answer: A

Rationale: In a 30-year-old man with a firm, 2-cm mass under his areola and no other symptoms, the most likely diagnosis is breast tissue. Gynecomastia is a common condition in males where there is proliferation of breast tissue. It typically presents as a firm subareolar mass and can occur due to hormonal imbalances, medication use, or underlying medical conditions. Given the lack of family history of breast cancer, absence of other symptoms, and the age of the patient, breast tissue is the most probable diagnosis in this case. Breast cancer is less likely in this scenario, especially without any additional concerning findings or family history. Fibrocystic disease and lymph node involvement are also less likely given the presentation of a firm mass under the areola.

Correct Answer: B

Rationale: Relief of the pain with bending at the waist is a key hallmark of spinal stenosis. This position helps relieve the pressure on the nerves in the spinal canal, which is often the root cause of the leg symptoms experienced by the patient. The symptoms described by Mr. Edwards, such as cramps in the calves after walking a certain distance, followed by relief with rest and recurrence upon walking again, are highly suggestive of spinal stenosis. This condition involves narrowing of the spinal canal, leading to compression of the nerves and resulting in symptoms like leg cramps, weakness, and difficulty walking, especially with prolonged activity. The relief of symptoms when bending forward (e.g., leaning on a shopping cart while walking) is a characteristic feature of neurogenic claudication associated with spinal stenosis.

Correct Answer: B

Rationale: The scenario described suggests that Ray experiences pain only when actively lifting his arm over his head, which indicates the issue is likely originating from structures outside of the joint itself. When the shoulder is moved passively (moved by an external force), there is full range of motion without pain, suggesting that the limitation and pain occur due to muscles, tendons, or ligaments surrounding the joint rather than within the joint itself. In this case, the joint disease is likely to be extra-articular, involving structures such as muscles or tendons rather than being articular in nature.

Correct Answer: A

Rationale: The most appropriate amount for a weekly weight reduction goal is typically .5 to 1 pound per week. This rate of weight loss is considered safe and sustainable in the long term. Losing weight too quickly (options B, C, D) can be harmful to your health and may lead to muscle loss, nutritional deficiencies, and a slow metabolism. Rapid weight loss is also harder to maintain in the long run. Gradual weight loss of .5 to 1 pound per week allows for healthy changes to diet and exercise habits, making it more likely to be maintained over time. It is also more likely to result in lasting weight loss and overall improvements in health and well-being.

Correct Answer: D

Rationale: The most likely explanation for the discrepancy between the patient's relatively normal blood pressure reading (118/92) and the presence of hypertensive changes in her retinas and mild proteinuria is that the process causing her retinopathy and kidney problems has resolved. Hypertensive changes in the retinas and proteinuria are typically signs of chronic uncontrolled hypertension, but they can also be residual manifestations of previously uncontrolled hypertension that has now been effectively treated.

Correct Answer: A

Rationale: The clinical presentation described is consistent with a Bartholin's gland infection, also known as Bartholin's abscess. The Bartholin's glands are located on each side of the vaginal opening and can become blocked, leading to glandular secretions accumulating and forming an abscess. Symptoms of Bartholin's gland infection include pain, swelling, and tenderness in the vulvar area. The pain can be severe and exacerbated by sitting, similar to what the patient is experiencing. On examination, a red, tense swelling to the side of the introitus is a characteristic finding.

Correct Answer: D

Rationale: Placing the patient in the left lateral decubitus position and auscultating with the bell is important to detect subtle sounds like the mitral stenosis murmur, opening snap of the mitral valve, and S3 and S4 gallops. The left lateral decubitus position helps bring the heart closer to the chest wall, allowing for better transmission of these sounds that may be missed in the supine position.
