Question 7#Print Question

A 52-year-old man presents for a routine physical examination. He has not been to a primary care physician since he was a teenager, and now he wants a colonoscopy since his friend was recently diagnosed with colon cancer. He denies any medical history and takes no medications. He is found to be hypertensive during his clinic appointment (164/98 mmHg), and the diagnosis of hypertension is later confirmed with the use of outpatient blood pressure monitoring. On examination, a bruit is heard over the left carotid artery, an S4 is heard on cardiac auscultation, and he has weak lower-extremity pulses. He has baseline laboratory tests drawn, is started on lisinopril, and is instructed to follow up for repeat laboratory work 1 week later. At the follow-up appointment, his blood pressure is 172/102 mmHg and the following laboratory results are seen.

What should be done next in the management of this patient? 

a. Add hydrochlorothiazide
b. Add metformin
c. Stop lisinopril
d. Continue the current management and repeat laboratory tests in 2 weeks

Question 8#Print Question

A 38-year-old woman presents to her physician with fatigue and edema. She is an IV drug abuser and has been diagnosed with chronic hepatitis C infection. A urinalysis shows 1+ protein, 1+ blood, and red blood cell (RBC) casts. The rest of her laboratory values are shown below.

  • Blood urea nitrogen 25 mg/dL
  • Creatinine   1.7 mg/dL
  • Total protein   6.1 g/dL
  • Albumin   3.7 g/dL
  • C3   68 mg/dL (normal range 75–175 mg/dL)
  • C4   <2 mg/dL (normal range 14–40 mg/dL)

Laboratory testing 2 weeks ago showed a normal creatinine (0.8 mg/dL). A renal biopsy is performed which shows glomerular crescent formation. Antinuclear antibody, antinuclear cytoplasmic antibody, and antiglomerular basement membrane (GBM) antibody testing is negative.

Which of the following is the most likely diagnosis?

a. Granulomatosis with polyangiitis
b. Systemic lupus erythematosus (SLE)
c. Membranoproliferative glomerulonephritis

  • Sodium   140 mEq/L
  • Potassium   3.2 mEq/L
  • Chloride   114 mEq/L
  • Bicarbonate   16 mEq/L
  • Phosphorus   1.9 mg/dL

An arterial blood gas shows that he has a pH of 7.3 and a PaCO2 of 35 mmHg. He has urine studies performed, which are significant for glucosuria, a urine pH of 7.8 after bicarbonate infusion, and a fractional excretion of bicarbonate of 25%.

Which of the following best represents the acid/base abnormality in this patient?

a. Anion gap metabolic acidosis with a compensatory respiratory alkalosis
b. Nonanion gap metabolic acidosis with a compensatory respiratory alkalosis
c. Anion gap metabolic acidosis with a primary respiratory acidosis
d. Nonanion gap metabolic acidosis with a primary respiratory acidosis
