A client with chronic renal failure is asking the nurse why her hemoglobin and hematocrit counts are low. Which of the following is the nurse's best response?
Your counts are low because of all the heparin you are receiving during dialysis
Your counts are low because your kidneys are no longer producing erythropoietin
Your counts are low because you are losing blood with each dialysis treatment
Your counts are low because you are not eating a diet rich in protein
The Correct Answer is B
Choice A reason: Heparin prevents clotting during dialysis but doesn’t reduce hemoglobin or hematocrit directly. It’s not a primary cause of anemia in renal failure, unlike erythropoietin deficiency.
Choice B reason: Kidneys in chronic renal failure fail to produce erythropoietin, a hormone stimulating red blood cell production, leading to low hemoglobin and hematocrit, the key cause here.
Choice C reason: Minor blood loss occurs in dialysis, but it’s not the primary reason for chronic anemia. Erythropoietin deficiency from renal failure has a greater impact on counts.
Choice D reason: Poor protein intake affects overall health but isn’t the main driver of anemia in renal failure. Erythropoietin loss from kidney dysfunction is the dominant factor.

Correct Answer is A
Explanation
Choice A reason: Hypothyroidism slows metabolism due to low thyroid hormone, reducing calorie burning and causing weight gain from fat accumulation and fluid retention in tissues.
Choice B reason: Diaphoresis (sweating) occurs in hyperthyroidism from excess metabolism raising body heat. Hypothyroidism causes dry skin and cold intolerance, not sweating.
Choice C reason: Exophthalmos, bulging eyes, results from Graves’ disease in hyperthyroidism due to orbital inflammation. Hypothyroidism doesn’t affect eye protrusion, making this unlikely.
Choice D reason: Palpitations stem from hyperthyroidism’s increased heart rate via excess thyroid hormone. Hypothyroidism slows heart rate, leading to bradycardia, not palpitations.
Correct Answer is D
Explanation
Choice A reason: Diphenhydramine, an antihistamine, treats allergies or sleep issues by blocking histamine, not addressing heart failure’s fluid overload or cardiac dysfunction.
Choice B reason: Epinephrine boosts heart rate and pressure in emergencies like anaphylaxis, but it worsens heart failure by increasing cardiac workload, not reducing fluid.
Choice C reason: Propylthiouracil treats hyperthyroidism by inhibiting thyroid hormone, unrelated to heart failure’s need for fluid management or cardiac support.
Choice D reason: Furosemide, a loop diuretic, reduces fluid overload in heart failure by increasing urine output, relieving pulmonary edema and systemic congestion effectively.
