Free APEA Customizable Study Plans Questions and Answers 1 — Questions and Answers
Question 1: A 45-year-old female presents with a complaint of fatigue, weight gain, and cold intolerance. Which of the following is the most appropriate initial test to evaluate her symptoms?
- Complete blood count (CBC)
- Serum TSH (Correct answer)
- Serum electrolytes
- Chest X-ray
Correct answer: Serum TSH
The patient's symptoms of fatigue, weight gain, and cold intolerance are classic indicators of hypothyroidism. The most appropriate initial test to evaluate thyroid function and diagnose hypothyroidism is a serum Thyroid-Stimulating Hormone (TSH) level. An elevated TSH level would suggest that the thyroid gland is underactive and not producing enough thyroid hormones, prompting the pituitary gland to release more TSH in an attempt to stimulate it.
Question 2: Which of the following is a common side effect of ACE inhibitors?
- Hypokalemia
- Hyperglycemia
- Dry cough (Correct answer)
- Bradycardia
Correct answer: Dry cough
A common and well-known side effect of ACE inhibitors (Angiotensin-Converting Enzyme inhibitors) is a persistent, dry cough. This cough is thought to be caused by the accumulation of bradykinin, a substance that is normally broken down by ACE. For patients who develop this bothersome cough, an Angiotensin Receptor Blocker (ARB) is often prescribed as an alternative, as ARBs do not affect bradykinin levels.
Question 3: A 60-year-old male with a history of smoking and hypertension presents with a new onset of hematuria. What is the most appropriate next step in management?
- Initiate antibiotics
- Order a urine culture
- Refer to urology for cystoscopy (Correct answer)
- Prescribe diuretics
Correct answer: Refer to urology for cystoscopy
New onset hematuria (blood in the urine) in a 60-year-old male with a history of smoking and hypertension is a red flag for genitourinary malignancy, particularly bladder cancer. Given these risk factors, a prompt referral to urology for cystoscopy is the most appropriate next step. Cystoscopy allows for direct visualization of the bladder and urethra to identify any tumors or other abnormalities that could be causing the bleeding.
Question 4: Which of the following vaccinations is recommended annually for all adults?
- Hepatitis B
- Tetanus-diphtheria
- Influenza (Correct answer)
- Varicella
Correct answer: Influenza
The influenza (flu) vaccine is recommended annually for all adults, typically in the fall, to protect against circulating strains of the influenza virus. This annual recommendation is due to the constant evolution of influenza viruses, requiring new vaccine formulations each year to provide effective immunity. Regular vaccination helps prevent severe illness, hospitalizations, and deaths associated with the flu.
Question 5: A 30-year-old female presents with a painful, erythematous nodule on her lower leg. She has a history of recurrent similar lesions. What is the most likely diagnosis?
- Cellulitis
- Erythema nodosum (Correct answer)
- Lipoma
- Folliculitis
Correct answer: Erythema nodosum
The description of a painful, erythematous nodule on the lower leg, especially with a history of recurrent similar lesions, is highly suggestive of erythema nodosum. This condition is a form of panniculitis, characterized by inflammation of the fat cells under the skin, resulting in tender, red nodules. It is often a reactive process associated with various underlying conditions, including infections, medications, or inflammatory diseases.
