Which electrolyte will be high in a client with hypoparathyroidism?
Phosphorus
Calcium
Magnesium
Potassium
The Correct Answer is A
Choice A reason: Hypoparathyroidism lowers PTH, reducing phosphorus excretion, raising serum levels as kidneys reabsorb more, while calcium drops, a classic imbalance.
Choice B reason: Calcium decreases in hypoparathyroidism due to low PTH, impairing bone resorption and gut absorption, opposite to being high, so this is incorrect.
Choice C reason: Magnesium isn’t directly regulated by PTH; hypoparathyroidism doesn’t consistently elevate it, staying normal unless other factors intervene.
Choice D reason: Potassium is unaffected by hypoparathyroidism, controlled by aldosterone and kidneys, not PTH, so it doesn’t rise with this condition.

Correct Answer is D
Explanation
Choice A reason: Increasing fiber binds dietary calcium, reducing absorption in hyperparathyroidism, aiding excretion, so this statement aligns with proper management.
Choice B reason: Furosemide enhances calcium excretion via urine, countering hyperparathyroidism’s high levels, making this an accurate understanding of treatment intent.
Choice C reason: Parathyroidectomy removes overactive glands, correcting calcium overproduction in hyperparathyroidism, a correct expectation reflecting disease management.
Choice D reason: Fluid restriction (1,000 mL) concentrates calcium, worsening hypercalcemia in hyperparathyroidism; increased fluids dilute it, so this needs correction.
Correct Answer is B
Explanation
Choice A reason: Dexamethasone, a steroid, reduces inflammation but doesn’t dissolve or prevent pulmonary embolism clots, irrelevant to acute anticoagulation needs here.
Choice B reason: Heparin, an anticoagulant, prevents clot growth in pulmonary embolism, stabilizing it to reduce further lung vessel occlusion, the standard initial treatment.
Choice C reason: Atropine treats bradycardia by increasing heart rate, not addressing pulmonary embolism’s clot, which requires anticoagulation, not cardiac pacing.
Choice D reason: Furosemide, a diuretic, manages fluid overload but doesn’t affect pulmonary embolism’s thrombus, focusing on volume, not clot dissolution or prevention.
