Question: 1 of 200
A patient on long-term lithium therapy develops polyuria and polydipsia. Which
mechanism best explains these symptoms?
Lithium-induced nephrogenic diabetes insipidus due to downregulation of aquaporin-2 channels
Lithium-induced central diabetes insipidus due to decreased ADH secretion
Lithium-induced osmotic diuresis due to glucosuria
Lithium-induced SIADH leading to water retention and dilutional hyponatremia

50,000/L five days after initiation. Which antibody is most likely responsible?
IgG antibody against heparin-platelet factor 4 complex
IgM antibody against platelet glycoprotein IIb/IIIa
IgE antibody against heparin itself
IgA antibody against endothelial cells

Question: 3 of 200
A patient with type 2 diabetes on metformin is prescribed a glucocorticoid for a severe
allergic reaction. Which metabolic effect is the nurse most concerned about?
Increased risk of lactic acidosis due to metformin accumulation
Hyperglycemia due to glucocorticoid-induced insulin resistance
Hypoglycemia due to additive effects of metformin and glucocorticoids
Metformin-induced vitamin B12 deficiency exacerbated by glucocorticoids

Question: 4 of 200
A patient on warfarin with an INR of 5.2 and no bleeding is given phytonadione
(vitamin K1). What is the primary rationale for using a low-dose (1-2.5 mg) oral route
rather than a high-dose subcutaneous route?
Low-dose oral vitamin K1 reverses INR more rapidly than high-dose subcutaneous
High-dose subcutaneous vitamin K1 increases risk of anaphylaxis
Low-dose oral vitamin K1 allows for more predictable INR reduction without overcorrection
Oral vitamin K1 has higher bioavailability than subcutaneous administration

Question: 5 of 200
A patient with HIV on tenofovir disoproxil fumarate (TDF) develops a serum creatinine
increase from 0.9 to 1.4 mg/dL. Which mechanism contributes to this nephrotoxicity?
Tenofovir causes acute interstitial nephritis via hypersensitivity reaction
Tenofovir accumulates in proximal tubular cells causing mitochondrial dysfunction
Tenofovir induces crystal nephropathy similar to acyclovir
Tenofovir causes glomerulonephritis via immune complex deposition

Question: 6 of 200

digoxin level is 3.5 ng/mL. Which ECG finding is most specific for digoxin toxicity?
Prolonged PR interval
Scooped ST segment depression
Bidirectional ventricular tachycardia
T wave inversion
