A nurse is assessing a client who is receiving levothyroxine for treatment of hypothyroidism. The nurse should recognize which of the following findings is a therapeutic response to this medication?
Decrease in body temperature
Increase in energy
Increase in weight
Decrease in appetite
The Correct Answer is B
Choice A reason: Decreased body temperature reflects hypothyroidism; levothyroxine raises metabolism, normalizing or increasing temperature, so this isn’t a therapeutic response.
Choice B reason: Increased energy occurs as levothyroxine restores thyroid hormone, boosting metabolism, reversing hypothyroidism’s fatigue, a key sign of effective treatment.
Choice C reason: Weight gain contradicts levothyroxine’s effect; it increases metabolism, aiding weight loss or stabilization, not gain, in hypothyroidism treatment.
Choice D reason: Decreased appetite isn’t typical; levothyroxine may normalize appetite as metabolism rises, not suppress it, differing from hypothyroidism’s effects.

Correct Answer is C
Explanation
Choice A reason: Fluid restriction doesn’t address hyperkalemia (6.4 mEq/L); it may concentrate potassium further, worsening the condition, as it’s unrelated to potassium excretion or shifting in this scenario.
Choice B reason: Neomycin, an antibiotic, reduces gut bacteria but isn’t used for hyperkalemia. It has no direct effect on potassium levels, making it irrelevant for this lab finding.
Choice C reason: Kayexalate binds potassium in the gut, facilitating its fecal excretion, effectively lowering serum levels (6.4 mEq/L) in hyperkalemia, aligning with urgent correction needs here.
Choice D reason: Sodium chloride and furosemide dilute and excrete potassium via urine, but Kayexalate is preferred for rapid gut-based removal when potassium is critically high (6.4 mEq/L).
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.
