A 55-year-old bookkeeper comes to your office for a routine visit. You note that on a previous visit for treatment of contact dermatitis, her blood pressure was elevated. She does not have prior elevated readings and her family history is negative for hypertension. You measure her blood pressure in your office today. Which of the following factors can result in a false high reading?

Correct Answer: A

Rationale: A tightly fitted blood pressure cuff can result in a false high reading by compressing the underlying artery too much, causing an inaccurate measurement. It is important to ensure that the blood pressure cuff is appropriately sized for the patient's arm to obtain an accurate reading. The other factors listed, such as the patient being seated quietly, measuring on a bare arm, and supporting the patient's arm at the correct level, all contribute to obtaining an accurate measurement of blood pressure.

Correct Answer: D

Rationale: The given symptoms of distant air sounds, late inspiratory crackles in both lower lobes, distant S1 and S2 heart sounds, and an S3 heart sound heard over the apex are all characteristic findings of left-sided heart failure. Distant air sounds and late inspiratory crackles indicate pulmonary congestion due to fluid accumulation in the lungs as a result of left-sided heart failure. The distant heart sounds and presence of an S3 are signs of left ventricular dysfunction. In contrast, pneumonia would typically present with more localized abnormal breath sounds and other symptoms such as fever and productive cough. Chronic obstructive pulmonary disease (COPD) would manifest with prolonged expiratory phase and wheezing, not late inspiratory crackles. Pleural pain is typically associated with sharp chest pain exacerbated by breathing movements, and it does not explain the constellation of symptoms described in this case. Therefore, the most likely diagnosis based on the provided symptoms

Correct Answer: B

Rationale: The presentation of multiple burning erosions on the shaft of the penis along with tender inguinal adenopathy is indicative of genital herpes caused by the herpes simplex virus (HSV). Primary herpes simplex infection typically presents with painful ulcers and lymphadenopathy. The ulcers are often shallow with well-defined borders and can be associated with systemic symptoms such as fever and malaise. In contrast, primary syphilis is characterized by a painless chancre at the site of infection, usually on the genitals. Chancroid can also present with painful ulcers, but it is less common in developed countries. Gonorrhea typically presents with urethral discharge, dysuria, or other symptoms of urethritis, rather than erosions on the penis shaft.

Correct Answer: D

Rationale: The group of lymph nodes that lie just behind the sternocleidomastoid muscles bilaterally are known as the posterior cervical lymph nodes. These lymph nodes are part of the superficial cervical lymph node chain, which is involved in draining lymph from the head and neck region. In the case described, the presence of sore throat, fever, and enlarged tonsils with exudates suggests a likely upper respiratory tract infection or tonsillitis, leading to the enlargement of the nearby lymph nodes. The posterior cervical lymph nodes are commonly examined in cases of upper respiratory infections and tonsillitis due to their proximity to the area of infection and inflammation.

Correct Answer: D

Rationale: A rectal polyp is a growth that originates from the inner lining of the rectum and protrudes into the rectal canal. It may present as a soft, smooth, nontender mass on digital rectal examination. Rectal polyps are usually benign, but some may have the potential to become cancerous if left untreated. Therefore, it is important to evaluate and remove polyps to prevent complications. In this case, the description of a pedunculated mass on the posterior wall of the rectum is most suggestive of a rectal polyp.

Correct Answer: D

Rationale: Audiometric testing is a very sensitive method for detecting hearing loss. It involves a series of tests that measure a person's ability to hear sounds at various frequencies and volumes. These tests can detect even subtle changes in hearing ability and provide detailed information on the type and degree of hearing loss. The whisper test and finger rub test are basic screening tests and are not as sensitive or comprehensive as audiometric testing. The tuning fork test is also used in evaluating hearing loss, but it is not as accurate or sensitive as audiometric testing. Overall, audiometric testing is considered the gold standard for diagnosing hearing loss due to its high sensitivity and ability to provide detailed information on the individual's hearing capabilities.

Correct Answer: A

Rationale: According to American Cancer Society recommendations, a woman should undergo a screening breast examination by a skilled clinician every year. Regular breast exams help in early detection of breast cancer, which can significantly improve outcomes and treatment options. Annual screenings are crucial in monitoring changes in breast health and detecting any abnormalities at the earliest stage possible. Therefore, it is advised that women follow this guideline to prioritize their breast health and well-being.

Correct Answer: B

Rationale: The dullness in the last intercostal space in the anterior axillary line on the left side with a deep breath is suggestive of splenomegaly. However, this finding alone is not definitive for an enlarged spleen. The size of the spleen can vary, and further examination is required to confirm if the spleen is indeed enlarged. Therefore, Option B is the most appropriate choice as it indicates that the spleen is possibly enlarged, and close attention should be paid to further examination to confirm its status. Further workup, such as imaging studies or blood tests, may be necessary to evaluate the size and function of the spleen in this case.

Correct Answer: C

Rationale: Marion's presentation of back pain associated with constipation and urinary retention is concerning for cauda equina syndrome. Cauda equina syndrome is a rare but serious condition caused by the compression of the bundle of nerves at the bottom of the spinal cord, known as the cauda equina. This compression can result in a variety of symptoms, including back pain, sciatica, changes in bowel and bladder function (such as constipation and urinary retention), as well as lower extremity weakness or numbness.
