Induration along the ventral surface of the penis suggests which of the following?

Correct Answer: C

Rationale: Peyronie's disease is a condition characterized by the formation of fibrous scar tissue in the penis, leading to the development of plaques or indurations along the shaft of the penis, typically on the ventral surface. These plaques can cause penile curvature, pain, and erectile dysfunction. Urethral stricture, testicular carcinoma, and epidermoid cysts are not typically associated with indurations along the ventral surface of the penis.

Correct Answer: A

Rationale: The information provided about the patient being treated for an asthma exacerbation and not being intubated falls under the category of adult illnesses. Asthma is a common respiratory condition that affects people of various ages but is more prevalent in adults. The fact that the patient was treated for an asthma exacerbation and has not required intubation indicates a relevant medical history related to adult illnesses and respiratory conditions. This information would be considered when evaluating and managing the patient's current health status and potential risks related to respiratory issues.

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: A

Rationale: The presence of a firm and immobile mass felt against the bowel wall during a rectal examination is concerning for a potential malignancy, such as colon cancer. Other conditions such as hemorrhoids or anal fissures are typically not associated with a mass that is firm and immobile. The "Valve of Houston" is a term that does not pertain to this scenario and is not a recognized medical entity. Therefore, the most likely diagnosis based on the given information is colon cancer, and further evaluation such as a colonoscopy would be warranted for definitive diagnosis and management.

Correct Answer: A

Rationale: The clinical presentation of this 17-year-old high school senior is concerning for a spontaneous pneumothorax. A spontaneous pneumothorax occurs when air enters the pleural space, resulting in lung collapse. Risk factors for spontaneous pneumothorax include tall, thin body habitus and smoking. In this case, the patient's sudden onset of right-sided chest pain and severe shortness of breath, along with absent breath sounds on the right side of the chest and hyperresonance on percussion, are consistent with a pneumothorax. The absence of lung sounds and fremitus on palpation over the right upper lobe further support this diagnosis. Chronic obstructive pulmonary disease (COPD) and asthma typically present with more chronic symptoms, while pneumonia is usually associated with fever, productive cough, and other signs of infection. Given the history and physical examination findings, spontaneous pneumothorax is the most

Correct Answer: C

Rationale: The obturator sign is a physical examination maneuver used to assess for irritation of the obturator muscle due to an inflamed appendix that is in close proximity. This pain is typically felt in the right lower quadrant or hypogastric region. The sign is elicited by passively flexing the hip and knee of the patient, then internally rotating the hip. An alternative method is to position the patient on her left side and ask her to raise her right thigh against resistance while the examiner provides counterpressure. Pain experienced by the patient with these maneuvers is consistent with obturator sign, indicating possible appendicitis. Hence, option C is the correct answer.

Correct Answer: A

Rationale: Anisocoria refers to a condition where the pupils are of unequal size. Pathologic causes of anisocoria can include conditions such as Horner's syndrome. Horner's syndrome is a rare disorder caused by damage to the sympathetic nerves of the face and eye. Symptoms can include a constricted pupil (miosis), drooping of the upper eyelid (ptosis), and decreased sweating in the affected area. This results in anisocoria, where the affected pupil is smaller than the unaffected pupil. Other options listed (B-D) do not typically lead to pathologic anisocoria.

Correct Answer: D

Rationale: Hypertension, or high blood pressure, is not typically associated with causing ulcers in the lower extremities. The most common causes of lower extremity ulcers are arterial insufficiency, venous insufficiency, and diminished sensation in pressure points. Arterial insufficiency leads to decreased blood flow to the lower extremities, causing tissue damage and ulcers. Venous insufficiency results in poor circulation and increased pressure in the veins, leading to ulcers. Diminished sensation in pressure points, often seen in conditions like diabetes, can cause ulcers due to lack of feeling and increased risk of trauma. So, hypertension is not directly related to the development of lower extremity ulcers.

Correct Answer: B

Rationale: In respiratory distress, the skin between the ribs moves inward with inspiration, a phenomenon known as retractions. This is a sign of increased work of breathing as the body tries to pull in more air due to difficulty in breathing. The inward movement of the skin between the ribs indicates that the individual is not able to generate enough negative pressure in the chest cavity to inhale properly. This can be seen in conditions such as asthma, pneumonia, or other respiratory issues. Skin retractions are a concerning sign and may indicate a severe respiratory compromise that requires immediate medical attention. The other options listed do not specifically describe a characteristic of respiratory distress.
