1. A 68-year-old male with a history of hypertension and type 2 diabetes presents for a
routine follow-up. His current blood pressure is 142/88 mmHg, and his hemoglobin A1c is
7.2%. He takes lisinopril and metformin. According to current guidelines, what is the most
appropriate next step in his pharmacological management?
A. Add a thiazide diuretic and increase metformin dosage
B. Initiate a calcium channel blocker or adjust the current ACE inhibitor therapy
C. Discontinue lisinopril and start an alpha-blocker
D. Add insulin glargine at bedtime without changing blood pressure medications
For patients with diabetes and hypertension, blood pressure targets are generally below
130/80 mmHg if risk is high, or below 140/90 mmHg depending on individual risk
stratification, but an ACE inhibitor or ARB is first-line when albuminuria is present. Since his
BP is 142/88 mmHg, optimizing the current regimen by adjusting the ACE inhibitor or adding
a complementary agent like a calcium channel blocker or thiazide diuretic is indicated,
whereas adding bedtime insulin is premature for an A1c of 7.2% managed on metformin
alone.
2. A 45-year-old female presents with a 3-month history of fatigue, weight gain of 10
pounds, constipation, and cold intolerance. Laboratory evaluation reveals a TSH of 9.8
mIU/L and a low free T4. Which of the following is the most appropriate initial medication
regimen?
A. Liothyronine (T3) monotherapy
B. Desiccated thyroid extract
C. Levothyroxine (T4) monotherapy
D. Methimazole combined with beta-blockers
Primary hypothyroidism is characterized by an elevated TSH and low free T4. Levothyroxine
(T4) monotherapy is the gold standard and first-line treatment due to its stable, predictable
conversion to T3 and once-daily dosing. Liothyronine and desiccated thyroid are not
recommended as initial therapy, and methimazole is used for hyperthyroidism, not
hypothyroidism.
3. A 55-year-old postmenopausal woman undergoes a routine dual-energy x-ray
absorptiometry (DEXA) scan, which reveals a T-score of -2.6 at the lumbar spine. She has
no history of fragility fractures. What is the diagnosis?
A. Normal bone density
B. Osteopenia
,C. Osteoporosis
D. Osteomalacia
According to World Health Organization criteria, a T-score of -2.5 or lower at the hip, spine,
or forearm defines osteoporosis. Osteopenia is defined as a T-score between -1.0 and -2.5.
Normal bone density is a T-score of -1.0 or higher. Osteomalacia is a mineralization defect,
not diagnosed strictly by T-score thresholds.
4. A nurse practitioner is evaluating a 28-year-old pregnant patient at 12 weeks gestation
who complains of urinary frequency and dysuria. Urinalysis reveals positive leukocyte
esterase and nitrites. Urine culture grows Escherichia coli >100,000 CFU/mL. Which of the
following antibiotics is contraindicated in this patient?
A. Nitrofurantoin
B. Amoxicillin-clavulanate
C. Ciprofloxacin
D. Cephalexin
Fluoroquinolones, such as ciprofloxacin, are contraindicated during pregnancy due to the
risk of cartilage damage and arthropathy in the developing fetus. Nitrofurantoin, amoxicillin-
clavulanate, and cephalexin are considered safe during pregnancy depending on the
gestational age and clinical context.
5. A 60-year-old male presents with a 2-week history of acute, excruciating pain, redness,
and swelling in the first metatarsophalangeal joint of his right foot. He admits to a heavy
intake of red meat and beer over the weekend. Arthrocentesis of the joint fluid is most
likely to reveal which of the following?
A. Positively birefringent rhomboid-shaped crystals
B. Negatively birefringent needle-shaped crystals
C. Gram-negative intracellular diplococci
D. Non-inflammatory fluid with no crystals
The clinical presentation is classic for acute gouty arthritis, which is caused by the deposition
of monosodium urate crystals in the joint. Under polarized light microscopy, these crystals
appear needle-shaped and negatively birefringent. Positively birefringent rhomboid crystals
are characteristic of pseudogout (calcium pyrophosphate deposition disease).
6. A 72-year-old male with chronic obstructive pulmonary disease (COPD) experiences
frequent exacerbations despite using a long-acting muscarinic antagonist (LAMA). He has
a smoking history of 45 pack-years and continues to smoke. Which of the following
interventions has the greatest impact on slowing the natural decline of lung function in this
patient?
A. Prescribing a long-acting beta2-agonist (LABA)
B. Initiating inhaled corticosteroid therapy
C. Smoking cessation counseling and pharmacotherapy
, D. Starting daily azithromycin prophylaxis
Smoking cessation is the single most effective intervention to alter the natural history and
slow the accelerated decline of forced expiratory volume in 1 second (FEV1) in patients with
COPD. While bronchodilators and anti-inflammatory agents improve symptoms and reduce
exacerbation rates, they do not modify the long-term decline in lung function as profoundly as
stopping smoking.
7. A 32-year-old female presents with persistent, dry nocturnal cough and episodic chest
tightness that worsens with exercise and cold air. Spirometry shows a normal baseline
FEV1/FVC ratio, but post-bronchodilator improvement in FEV1 is 14% and 200 mL.
What is the most likely diagnosis?
A. Gastroesophageal reflux disease
B. Asthma
C. Chronic bronchitis
D. Vocal cord dysfunction
The clinical history of episodic cough and chest tightness triggered by exercise and cold air,
combined with reversible airflow obstruction on spirometry (an increase in FEV1 by greater
than 12% and 200 mL after bronchodilator use), is diagnostic for asthma.
8. A 50-year-old male presents with fatigue, pruritus, and right upper quadrant discomfort.
Laboratory tests reveal an elevated alkaline phosphatase and elevated anti-mitochondrial
antibodies (AMA). What is the most likely diagnosis?
A. Primary sclerosing cholangitis
B. Primary biliary cholangitis
C. Nonalcoholic steatohepatitis
D. Autoimmune hepatitis
Primary biliary cholangitis (formerly primary biliary cirrhosis) classically presents with
fatigue, pruritus, and cholestatic liver enzyme abnormalities (elevated alkaline phosphatase) in
middle-aged women or men, with high specificity for anti-mitochondrial antibodies (AMA).
Primary sclerosing cholangitis is associated with inflammatory bowel disease and p-ANCA,
not AMA.
9. A 21-year-old college student presents with a 3-day history of fever, sore throat, severe
fatigue, and posterior cervical lymphadenopathy. Palpation of the abdomen reveals mild
splenomegaly. A rapid heterophile antibody test is negative. What is the most appropriate
next step?
A. Prescribe amoxicillin for suspected streptococcal pharyngitis
B. Order Epstein-Barr virus (EBV) VCA IgM and IgG titers
C. Perform an immediate emergency splenectomy
D. Reassure the patient that symptoms are psychosomatic
