NURSING CONSIDERATIONS
Assess:

• 
Hypocalcemia:
nausea, vomiting, constipation, thirst, dysrhythmias, hypocalcemia, paresthesia, twitching, laryngospasm, Chvostek’s sign, Trousseau’s sign;
hypercalcemia:
thirst, nausea, vomiting, dysrhythmias

• 
Dehydration/hypovolemia: should be corrected during treatment of hypercalcemia, before therapy, maintain adequate urine output

• 
Monitor WBCs, platelets, electrolytes, creatinine, BUN, Hgb/Hct before beginning treatment

• 
Dental health:
cover with antiinfectives for dental extractions

• 
Temperature may be elevated during the first 3 days after a dose, risk of fever increases as dose increases

• 
Renal disease: Max 90-mg single dose, longer infusions >2 hr may increase risk for renal toxicity

• 
Bone pain; use analgesics

• 
I&O, check for fluid overload edema, crackles, increased B/P; BUN, creatinine

Evaluate:

• 
Therapeutic response: decreased calcium levels

Teach patient/family

• 
To notify prescriber if pregnancy is planned or suspected, pregnancy (D)

• 
To report hypercalcemic relapse: nausea, vomiting, bone pain, thirst; unusual muscle twitching, muscle spasms; severe diarrhea, constipation

• 
To continue with dietary recommendations, including calcium and vit D

• 
To obtain analgesic from provider for bone pain

• 
That, if nausea, vomiting occur, small, frequent meals may help

• 
To report ocular symptoms to prescriber: blurred vision, edema, inflammation
