CHAPTER 11 Fluids and Electrolytes^443
NURSING INTERVENTION
- Monitor intake and output.
- Monitor vital signs; may see hypotension with intravenous phosphate infusion.
- Explain to the patient:
- Diet of turkey, skim milk and milk products, and dried fruits.
Hyperphosphatemia
WHAT WENT WRONG?
Hyperphosphatemia is a higher-than-normal amount of phosphorus in the blood.
Patients may develop increased phosphate levels as a result of renal insufficiency,
increase in phosphorus intake (supplements, laxatives, enemas, excess vitamin D),
hypoparathyroidism, rhabdomyolysis, or as a result of cell destruction from chemo-
therapy. As phosphate levels increase, calcium levels decrease.
PROGNOSIS
Correction or management of the underlying cause is necessary to help restore the
electrolyte balance.
HALLMARK SIGNS AND SYMPTOMS
- Asymptomatic
- Symptoms of underlying disorder, such as renal disease
- May see symptoms of coexisting electrolyte disorders, such as hypocalcemia
INTERPRETING TEST RESULTS
- Phosphorus > 4.6 mEq/L in blood serum.
