Which area of the arm drains to the epitrochlear nodes?
- A. Ulnar surface of the forearm and hand, little and ring fingers, and ulnar middle finger
- B. Radial surface of the forearm and hand, thumb and index fingers, and radial middle finger
- C. Ulnar surface of the forearm and hand; second, third, and fourth fingers
- D. Radial surface of the forearm and hand; second, third, and fourth fingers
Correct Answer: A
Rationale: The area of the arm that drains to the epitrochlear nodes includes the ulnar surface of the forearm and hand, little and ring fingers, and the ulnar side of the middle finger. The epitrochlear nodes are located in the medial aspect of the arm above the elbow, close to the insertion of the biceps brachii muscle. These nodes receive lymphatic drainage from the above-mentioned areas and play a role in the immune response against infections in these regions.

A 23-year-old graduate student comes to your clinic for evaluation of a urethral discharge. As the provider, you need to get a sexual history. Which one of the following questions is inappropriate for eliciting the information?
- A. Are you sexually active?
- B. When was the last time you had intimate physical contact with someone, and did that contact include sexual intercourse?
- C. Do you have sex with men, women, or both?
- D. How many sexual partners have you had in the last 6 months?
Correct Answer: B
Rationale: While it is important to ask about recent sexual activity and whether it included sexual intercourse, using the term "intimate physical contact" is not specific enough. This question could potentially lead to misinterpretation or confusion regarding what types of activities are being referred to. It is more appropriate to directly ask about sexual intercourse when obtaining a sexual history. The other options are all appropriate questions to elicit information about the patient's sexual history.
Which of the following events occurs at the start of diastole?
- A. Closure of the tricuspid valve
- B. Opening of the pulmonic valve
- C. Closure of the aortic valve
- D. Production of the first heart sound (S )
Correct Answer: B
Rationale: At the start of diastole, the ventricles relax and begin to fill with blood from the atria. As this relaxation phase begins, the pulmonic valve opens to allow blood to flow from the right ventricle to the pulmonary artery and then to the lungs for oxygenation. This marks the beginning of diastole, the period of the cardiac cycle when the heart is filling with blood. The closure of the tricuspid valve, closure of the aortic valve, and production of the first heart sound (S1) occur during systole, the phase of the cardiac cycle when the heart is contracting to pump blood out to the body.
You are excited about a positive test finding you have just noticed on physical examination of your patient. You go on to do more examination, laboratory work, and diagnostic tests, only to find that there is no sign of the disease you thought would correlate with the finding. This same experience happens several times. What should you conclude?
- A. Consider not doing this test routinely.
- B. Use this test when you have a higher suspicion for a certain correlating condition.
- C. Continue using the test, perhaps doing less laboratory work and diagnostics.
- D. Omit this test from future examinations.
Correct Answer: B
Rationale: The repeated scenario of finding a positive test result that does not correlate with the suspected disease indicates a lack of specificity for the test in question. In such cases, it is important to use the test when there is a higher suspicion for a specific condition that is known to correlate with the finding. By using the test selectively in situations where it is more likely to provide accurate information, its utility can be maximized and unnecessary further workup can be avoided. This approach allows for a more targeted and efficient use of resources in the diagnostic process.
A patient presents for evaluation of a sharp, aching chest pain which increases with breathing. Which anatomic area would you localize the symptom to?
- A. Musculoskeletal
- B. Reproductive
- C. Urinary
- D. Endocrine
Correct Answer: A
Rationale: The symptom described - sharp, aching chest pain that increases with breathing - is typically associated with musculoskeletal issues. The pain worsening with breathing suggests a connection to the movements of the chest wall, which could involve the muscles, bones, or joints in that area. Conditions such as costochondritis (inflammation of the cartilage that connects a rib to the breastbone) or muscle strains in the chest wall are common causes of chest pain that worsens with breathing. This localization to the musculoskeletal system is based on the characteristics of the pain and how it is affected by breathing, helping to narrow down the differential diagnosis.
A 58-year-old teacher presents to your clinic with a complaint of breathlessness with activity. The patient has no chronic conditions and does not take any medications, herbs, or supplements. Which of the following symptoms is appropriate to ask about in the cardiovascular review of systems?
- A. Abdominal pain
- B. Orthopnea
- C. Hematochezia
- D. Tenesmus
Correct Answer: B
Rationale: Orthopnea is a symptom characterized by difficulty breathing while lying flat that improves when sitting or standing upright. This symptom is specifically related to cardiovascular conditions, such as heart failure, in which fluid accumulates in the lungs when lying down. Considering the patient's complaint of breathlessness with activity and the need to assess for cardiovascular issues, asking about orthopnea would be most appropriate to gain insights into potential heart-related causes of the symptoms. Abdominal pain (A), hematochezia (C), and tenesmus (D) are not typically associated with cardiovascular conditions and are less relevant to the patient's presentation.
