MOD 10- Evolve AQ-Ch. 63-Care of Patients with Problems of the Thyroid and Parathyroid Glands
What are the possible findings of a radiographic analysis performed on a patient with hyperparathyroidism? Select all that apply. Correct Bone cysts Correct Renal calculi Correct Osteoporosis Osteopetrosis Osteosclerosis
Bone lesions in hyperparathyroidism are due to an increased rate of bone destruction and may result in pathologic fractures such as bone cysts. High levels of parathyroid hormone (PTH) cause renal calculi and deposits of calcium in the soft tissue of the kidney. Due to deficiency of calcium due to hyperparathyroidism, increased bone destruction occurs that may result in osteoporosis. Osteopetrosis is an extremely rare inherited disorder whereby the bones harden, becoming denser, in contrast to osteoporosis. Osteosclerosis is a type of osteopetrosis that involves abnormal hardening of bone involving increased skeletal density.
The nurse is assessing a patient with a parathyroid disorder. Which laboratory findings would support a diagnosis of hyperparathyroidism? Select all that apply. Correct Vitamin D level of 30 ng/mL Correct Serum calcium level of 11 mg/dL Serum magnesium level of 2 mEq/L Correct Serum phosphorus level of 2.5 mg/dL Correct Urine cyclic adenosine monophosphate (cAMP) level of 55 nmol/L
In hyperparathyroidism, vitamin D levels may or may not increase. The normal level of vitamin D is 25 to 80 ng/mL. The normal serum calcium level is 9.0 to 10.5 mg/dL; this level is increased in patients with hyperparathyroidism. The normal urine cAMP level is 18.3 to 45.4 nmol/L; this level is increased in patients with hyperparathyroidism. Thus, a vitamin D level of 30 ng/mL, serum calcium level of 11 mg/dL, and urine cAMP level of 55 nmol/L confirms hyperparathyroidism. As in normal serum magnesium level is 1.3 to 2.1 mEq/L and would be increased with hyperparathyroidism. In normal serum, phosphorus level is 3.0 to 4.5 mg/dL; and it would be decrease with hyperparathyroidism. Serum magnesium levels of 2 mEq/L and is normal and do not indicate hyperparathyroidism.
