Nokea
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 sudden, painless unilateral vision loss may be caused by which of the following?
- A. Retinal detachment
- B. Corneal ulcer
- C. Acute glaucoma
- D. Uveitis
Correct Answer: A
Rationale: A sudden, painless unilateral vision loss may be caused by a retinal detachment. Retinal detachment occurs when the retina, which is the light-sensitive tissue lining the back of the eye, pulls away from its normal position. This can lead to visual disturbances, including sudden loss of vision in one eye. Retinal detachment can be a medical emergency and requires prompt evaluation and treatment to prevent permanent vision loss. Other conditions mentioned in the choices, such as corneal ulcer, acute glaucoma, and uveitis, may also cause vision problems but are less likely to present with a sudden and painless unilateral vision loss as a primary symptom.
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 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.
He is concerned about his weight. Based on this information, what is appropriate counsel for the patient during the visit?
- A. Refer the patient to a nutritionist because he is anorexic.
- B. Reassure the patient that he has a normal body weight.
- C. Give the patient information about reduction of fat, cholesterol, and calories because he is overweight.
- D. Give the patient information about reduction of fat and cholesterol because he is obese.
Correct Answer: C
Rationale: The appropriate counsel for the patient during the visit would be to give information about the reduction of fat, cholesterol, and calories because he is concerned about his weight. This option addresses the patient's concern and provides guidance on making healthier choices to manage weight. Referring the patient to a nutritionist because he is anorexic (Option A) is not appropriate based on the information provided. Reassuring the patient that he has a normal body weight (Option B) may not address his concerns about weight. Giving the patient information about reducing fat and cholesterol only because he is obese (Option D) does not cover all aspects of a healthy diet such as managing calorie intake.
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.
