A nurse is collecting data from a client who has a calcium level of 12 mg/dL (9-10.5 mg/dL). Which of the following manifestations should the nurse expect?

Hypotension

Decreased deep tendon reflexes

Diarrhea

Increased appetite

Answer and Explanation

The Correct Answer is B

A. Hypotension: Hypercalcemia (high calcium levels) typically causes increased blood pressure, not hypotension.

B. Decreased deep tendon reflexes: High calcium levels can depress neuromuscular function, leading to diminished or absent deep tendon reflexes. This is a common finding in hypercalcemia.

C. Diarrhea: Hypercalcemia is more commonly associated with constipation, not diarrhea.

D. Increased appetite: Hypercalcemia does not cause increased appetite. It often leads to symptoms such as nausea, vomiting, or a reduced appetite.

Correct Answer is C

Explanation

. "Bradycardia is an early indicator of a pneumothorax.": Tachycardia, not bradycardia, is an early sign of pneumothorax.

B. "Administer a bronchodilator to the child after chest percussion therapy.": Bronchodilators are typically administered before chest physiotherapy to open airways and enhance mucus clearance.

C. "Engage the child in daily aerobic exercise.": Exercise promotes lung function, airway clearance, and overall physical health in children with cystic fibrosis.

D. "A pigeon-shaped chest might become evident as the disease progresses.": This is incorrect; barrel chest deformities, not pigeon chest, are associated with cystic fibrosis.

A. Sodium polystyrene sulfonate (Kayexolate) B. Lactulose C. Acetylcysteine D. Potassium iodide

Correct Answer is A

Explanation

A. Sodium polystyrene sulfonate (Kayexalate): This medication is used to treat hyperkalemia (high potassium levels) by exchanging sodium ions for potassium ions in the intestines, which helps lower potassium levels. The client’s potassium level is dangerously high at 6.2 mEq/L, so this is the most appropriate treatment.

B. Lactulose: Lactulose is used to treat hyperammonemia in liver failure or constipation. It has no role in managing elevated potassium levels.

C. Acetylcysteine: Acetylcysteine is used to treat acetaminophen overdose or as a mucolytic. It is not indicated for hyperkalemia.

D. Potassium iodide: Potassium iodide is used to protect the thyroid from radiation exposure or to treat certain types of thyroid conditions, not for hyperkalemia.
