Erythropoietin is a hormone produced by the kidney. What will a deficiency of erythropoietin in a patient in chronic renal failure result in?
Hypertension as a result of the increased, concentrated blood volume.
Elevated lipid levels in the bloodstream, contributing to accelerated atherosclerosis.
Anemia as a result of the diminished number of red blood cells being produced.
Diminished immunologic function with fewer white blood cells.
The Correct Answer is C
A. Hypertension as a result of the increased, concentrated blood volume: Hypertension in chronic kidney disease is due to fluid overload and renin-angiotensin-aldosterone system activation, not erythropoietin deficiency.
B. Elevated lipid levels in the bloodstream, contributing to accelerated atherosclerosis: Dyslipidemia in chronic kidney disease is unrelated to erythropoietin deficiency.
C. Anemia as a result of the diminished number of red blood cells being produced: Erythropoietin stimulates red blood cell production; its deficiency in chronic renal failure leads to anemia.
D. Diminished immunologic function with fewer white blood cells: White blood cell production is not directly affected by erythropoietin deficiency.

Correct Answer is ["7.5"]
Explanation
Order: 750 mg PO
Available: 0.5 g/5 mL
Convert 0.5 g to mg:
0.5g=500 mg
To calculate the volume:
Volumetoadminister= (Ordered dose /Available concentration)× Volumeperavailabledose
= (750mg /500 mg) × 5ml
= 7.5 ml

B. Contact the Rapid Response Team: Pink-tinged urine does not indicate a medical emergency requiring the Rapid Response Team.
C. Promptly notify the healthcare provider: This finding does not require immediate notification unless accompanied by significant bleeding, clots, or other abnormal symptoms.
