2020 HESI Pharmacology Version 1 – Questions 1
through 100
1) A nurse is caring for a client with hyperparathyroidism and notes that the client's
serum calcium level is 13 mg/dL. Which medication should the nurse prepare to
administer as prescribed to the client?
1. Calcium chloride
2. Calcium gluconate
3. Calcitonin (Miacalcin)
4. Large doses of vitamin D 3. Calcitonin (Miacalcin)
Rationale:
The normal serum calcium level is 8.6 to 10.0 mg/dL. This client is experiencing
hypercalcemia. Calcium gluconate and calcium chloride are medications used for
the treatment of tetany, which occurs as a result of acute hypocalcemia. In
hypercalcemia, large doses of vitamin D need to be avoided. Calcitonin, a thyroid
hormone, decreases the plasma calcium level by inhibiting bone resorption and
lowering the serum calcium concentration.
2.) Oral iron supplements are prescribed for a 6-year-old child with iron deficiency
anemia. The nurse instructs the mother to administer the iron with which best food
item?
1. Milk
2. Water
3. Apple juice
4. Orange juice 4. Orange juice
Rationale:
Vitamin C increases the absorption of iron by the body. The mother should be
instructed to administer the medication with a citrus fruit or a juice that is high in
vitamin C. Milk may affect absorption of the iron. Water will not assist in absorption.
Orange juice contains a greater amount of vitamin C than apple juice.
3.) Salicylic acid is prescribed for a client with a diagnosis of psoriasis. The nurse
monitors the client, knowing that which of the following would indicate the presence
of systemic toxicity from thismedication?
1. Tinnitus
2. Diarrhea

Salicylic acid is absorbed readily through the skin, and systemic toxicity (salicylism)
can result. Symptoms include tinnitus, dizziness, hyperpnea, and psychological
disturbances. Constipation and diarrhea are not associated with salicylism.
4.) The camp nurse asks the children preparing to swim in the lake if they have
applied sunscreen. The nurse reminds the children that chemical sunscreens are
most effective when applied:
1. Immediately before swimming
2. 15 minutes before exposure to thesun
