Nokea
A patient is concerned about a dark skin lesion on her anterolateral abdomen. It has not changed, and there is no discharge or bleeding. On examination there is a medium brown circular lesion on the anterolateral wall of the abdomen. It is soft, has regular borders, is evenly pigmented, and is about 7 mm in diameter. What is this lesion?
- A. Melanoma
- B. Dysplastic nevus
- C. Supernumerary nipple
- D. Dermatofibroma
Correct Answer: D
Rationale: Given the description provided, the lesion appears to be a dermatofibroma. Dermatofibromas are common benign skin lesions that typically present as a firm, solitary nodule on the skin. They commonly occur on the lower extremities but can also be found on the trunk. The characteristics of a dermatofibroma include being firm to the touch, having regular borders, being evenly pigmented, and a diameter typically less than 1 cm to 2 cm. They are usually painless and do not change significantly over time.

His head, eyes, ears, nose, and throat examinations are unremarkable. His cardiac examination is normal. On examination of his chest, the diameter seems enlarged. Breath sounds are decreased throughout all lobes. Rhonchi are heard over all lung fields. There is no area of dullness and no increased or decreased fremitus. What thorax or lung disorder is most likely causing his symptoms?
- A. Spontaneous pneumothorax
- B. Chronic obstructive pulmonary disease (COPD)
- C. Asthma
- D. Pneumonia
Correct Answer: B
Rationale: The patient's presentation with an enlarged chest diameter, decreased breath sounds throughout all lobes, and the presence of rhonchi over all lung fields is suggestive of a chronic condition that affects the entire respiratory system. These findings are classic for COPD, a progressive lung disease characterized by airflow limitation. The breath sounds are decreased due to airflow obstruction, and the presence of rhonchi indicates mucus production and airway inflammation commonly seen in COPD. In contrast, a spontaneous pneumothorax would typically present with sudden chest pain and shortness of breath, often in a younger patient with risk factors such as smoking. Asthma would present with wheezing, shortness of breath, and possibly a history of atopy or allergies. Pneumonia would typically present with fever, cough, and focal findings on chest examination, such as crackles or bronchial breath sounds over a consolidated area. In
A tender, painful swelling of the scrotum should suggest which of the following?
- A. Acute epididymitis
- B. Strangulated inguinal hernia
- C. Torsion of the spermatic cord
- D. All of the above
Correct Answer: A
Rationale: A tender, painful swelling of the scrotum is a common symptom of acute epididymitis, which is the inflammation of the epididymis. The epididymis is a tube located at the back of the testicle that stores and transports sperm. In acute epididymitis, the swelling is usually accompanied by pain, tenderness, redness, and warmth in the affected area. Other symptoms may include fever, chills, and discharge from the penis. Prompt medical evaluation and treatment are necessary to prevent complications such as abscess formation or chronic epididymitis. Strangulated inguinal hernia and torsion of the spermatic cord may present with severe pain and swelling in the scrotum, but they have distinct mechanisms and require different management approaches.
To hear a soft murmur or bruit, which of the following may be necessary?
- A. Asking the patient to hold her breath
- B. Asking the patient in the next bed to turn down the TV
- C. Checking your stethoscope for air leaks
- D. All of the above
Correct Answer: D
Rationale: To hear a soft murmur or bruit clearly, it is important to minimize any background noise or distractions that may interfere with your ability to auscultate effectively. Therefore, asking the patient to hold her breath (choice A) can help reduce noise caused by the patient's respiration. Asking the patient in the next bed to turn down the TV (choice B) can also help eliminate external noise that may disrupt your ability to hear subtle sounds. Checking your stethoscope for air leaks (choice C) is crucial to ensure that you are hearing sounds accurately and not being affected by any equipment issues. By combining these strategies, you can create an optimal environment for listening to soft murmurs or bruits.
A 28-year-old married clothing sales clerk comes to your clinic for her annual examination. She requests a refill on her birth control pills. Her only complaint is painless bleeding after intercourse. She denies any other symptoms. Her past medical history consists of two spontaneous vaginal deliveries. Her past six Pap smears have all been normal. She is married and has two children. Her mother is in good health and her father has high blood pressure. On examination you see a young woman appearing healthy and relaxed. Her vital signs are unremarkable and her head, eyes, ears, throat, neck, cardiac, lung, and abdominal examinations are normal. Visualization of the perineum shows no lesions or masses. Speculum examination shows a red mass at the os. On taking a Pap smear the mass bleeds easily. Bimanual examination shows no cervical motion tenderness and both ovaries are palpated and nontender. What is the most likely diagnosis for the abnormality of her cervix?
- A. Carcinoma of the cervix
- B. Mucopurulent cervicitis
- C. Cervical polyp
- D. Retention cyst
Correct Answer: C
Rationale: Given the patient's history and presentation, the most likely diagnosis for the abnormality seen on examination is a cervical polyp. Cervical polyps are benign growths that arise from the mucosal surface of the cervix. They are typically red or purple in color and can bleed easily, especially when touched, as in this case with the Pap smear causing bleeding. Cervical polyps are usually asymptomatic but can present with painless bleeding, particularly after intercourse. In this patient, the visualization of a red mass at the os during speculum examination and the finding of bleeding with manipulation support the diagnosis of a cervical polyp. Additionally, the absence of other significant findings on examination and the patient's overall healthy appearance further support this benign diagnosis. Further evaluation with possible removal of the polyp may be warranted for confirmation and to alleviate the bleeding symptoms.
Which of the following is consistent with good percussion technique?
- A. Allow all of the fingers to touch the chest while performing percussion.
- B. Maintain a stiff wrist and hand.
- C. Leave the plexor finger on the pleximeter after each strike.
- D. Strike the pleximeter over the distal interphalangeal joint.
Correct Answer: C
Rationale: Leaving the plexor finger on the pleximeter after each strike is consistent with good percussion technique. This helps to maintain stability and precision during percussion by providing a consistent point of contact for accurate assessment of the underlying structures. This technique also helps to control the force and angle of the percussive strike, ensuring accurate interpretation of the resulting sounds produced. Maintaining this contact can enhance the effectiveness of percussion as a diagnostic tool in physical examinations.
