A 56-year-old homosexual man presents with itching, anorectal pain, and tenesmus of 1 week's duration. Rectal examination reveals generalized tenderness without frank prostate abnormalities. Which of the following is most likely?

Correct Answer: C

Rationale: Given the patient's presentation of itching, anorectal pain, and tenesmus, along with rectal examination findings of generalized tenderness without prostate abnormalities, proctitis is the most likely diagnosis. Proctitis is inflammation of the rectal lining and is commonly associated with symptoms such as rectal pain, itching, tenesmus (feeling of incomplete defecation), and sometimes rectal bleeding. It can have various causes, including sexually transmitted infections (such as gonorrhea, chlamydia), inflammatory bowel disease, radiation therapy, or trauma.

Correct Answer: C

Rationale: Scrotal edema refers to swelling of the scrotum, which can be caused by various reasons such as infection, inflammation, trauma, or fluid collection. In this case, the examination findings of generalized swelling of the scrotum with no discrete masses or bulges on palpation suggest scrotal edema as the most likely diagnosis. The absence of bulges when a finger is placed through the inguinal rings with bearing down rules out a scrotal hernia. Hydrocele typically presents as a painless fluid-filled sac around the testicle, but there are no specific findings mentioned in the scenario to suggest a hydrocele. Varicocele involves dilated veins in the scrotum and may present as a soft lump that feels like a "bag of worms," which is not described in the examination findings provided.

Correct Answer: C

Rationale: Diplopia occurring when one eye is covered is a condition known as monocular diplopia. This symptom is typically not caused by problems within the eye itself, such as irregularities in the cornea or lens. Instead, monocular diplopia with one eye covered is more likely to be an indication of a neurological issue, often involving the brainstem. Lesions or damage in the brainstem can disrupt the normal coordination of eye movements, leading to the perception of double vision when one eye is closed. Weakness of CN III (oculomotor nerve) or CN IV (trochlear nerve) may cause diplopia when both eyes are open, but it would not typically manifest as monocular diplopia.

Correct Answer: C

Rationale: It is important to show empathy and address Mrs. Donelan's feelings about missing her husband. By asking why Bill is not there, you are opening the door for her to talk about her emotions and potentially offer support or resources. This can help build a stronger patient-provider relationship and address any underlying emotional concerns she may have. It is important to prioritize the patient's emotional well-being along with their physical health during the visit.

Correct Answer: B

Rationale: When conducting a health history assessment, the components typically include the review of systems, present illness, and personal and social items. The review of systems involves asking specific questions related to each system of the body to gather comprehensive information about the patient's overall health. Present illness focuses on the current chief complaint and symptoms the patient is experiencing. Personal and social items encompass details such as lifestyle habits, family history, medical history, and social support systems. The thorax and lungs are typically assessed as part of the physical examination, not specifically in the health history documentation.

Correct Answer: D

Rationale: The most important question to ask in this scenario would be if the patient has tried to lose weight. Given the patient's significant unintentional weight loss (from 140 to 110 pounds in a year), especially in the context of a chronic cough and a long history of smoking, lung cancer becomes a top concern. Unintentional weight loss is a common symptom seen in patients with lung cancer. Therefore, understanding if the weight loss was intentional or unintentional can provide crucial information in the diagnostic evaluation for possible lung cancer.

Correct Answer: B

Rationale: Coronary artery disease (CAD) is a significant risk factor for peripheral vascular disease (PVD). CAD is a condition where plaque builds up in the coronary arteries that supply blood to the heart muscle. This process is called atherosclerosis. Similarly, in PVD, atherosclerosis occurs in the peripheral arteries, affecting blood flow to the extremities, most commonly the legs. Individuals with CAD often have systemic atherosclerosis, which puts them at higher risk for developing PVD. Therefore, it is important for the 72-year-old teacher with CAD to be aware of this risk factor for PVD and consider appropriate screening and preventive measures.

Correct Answer: B

Rationale: Since the baby is exhibiting jaundice, which is a condition characterized by the yellowing of the skin, it is important to inquire about the family history of liver diseases. Jaundice can be a sign of liver dysfunction or disease, so understanding the family history of liver diseases can provide valuable insights into potential underlying causes for the baby's jaundice. In this case, it is crucial to explore this area further to determine if there may be any genetic predispositions or familial conditions that could be contributing to the baby's presentation of jaundice.

Correct Answer: C

Rationale: Splitting of the second heart sound is when the aortic and pulmonic valves close at slightly different times, resulting in two distinct components to the sound. This split is best heard over the apex of the heart, typically with the diaphragm of the stethoscope. The aortic component is heard first and represents closure of the aortic valve, followed by the pulmonic component, representing closure of the pulmonic valve. The split can narrow during inspiration and widen during expiration, which is important to keep in mind during assessment.
