QUESTION 1
1. Mr. Jeffers was admitted 2 days ago for a carotid endarterectomy. A Foley
catheter was inserted intraoperatively and remains in place. His urine output has
declined markedly despite continued IV fluid infusion. Today his morning labs
reveal a BUN of 19 mg/dL and a creatinine of 2 mg/dL. A leading differential
includes:
A. Foley lodged in the urethra causing post-renal failure
B. Decreased renal perfusion causing prerenal failure
C. Age-related decreased eGFR causing prerenal failure
D. Post-surgical rhabdomyolysis causing intrarenal failure
Answer:
• D. Post-surgical rhabdomyolysis causing intrarenal failure
During surgery, muscles and injured. This can result into rhabdomyolysis, which is
the breakdown of muscles to release proteins. The excess proteins causes an
,increased level of creatinine.
Mr. Jeffers is from surgery (post-surgical) and his creatinine levels are above
normal. The normal creatinine levels range from 0.6mg/dl to 1.2mg/dl. Thus, the
most likely differential is: Post-surgical rhabdomyolysis causing intrarenal
failure.

QUESTION 2
1. Janet is admitted with symptomatic tachycardia. Her pulse is 160 b.p.m.
and she is weak, diaphoretic, and anxious. Physical examination reveals a 5’4” 107

racing pulse. Her blood pressure is 140/100 mm Hg. Temperature and respiratory
rate are within normal limits. The patient admits to having a “thyroid condition”

A. Hashimoto’s thyroiditis
B. Cushing’s syndrome
C. Grave’s disease

, QUESTION 3
1. Systemic lupus erythematosis (SLE) is a multiorgansystem autoimmune
disorder that can prevent with a wide variety of manifestations. Which clinical
triad should prompt an evaluation for SLE?
A. Fever, normal white count, elevated sedimentation rate
B. Hyperkalemia, hyponatremia, low blood pressure
C. Leukocytosis, hyperglycemia, hypokalemia
D. Joint pain, rash,
fever 1 points
QUESTION 4
1. A patient presents with profound vertigo of acute onset yesterday. She can
barely turn her head without becoming very vertiginous; she is nauseous and just
doesn’t want to move. This morning when she tried to get out of bed she felt like
she was pushed back down. The vertigo is reproducible with cervical rotation.
The patient denies any hearing loss or tinnitus, she has no fever or other
symptoms. The AGACNP knows that the most helpful intervention will probably
be:
A. Meclizine
B. Diazepam
