ATI PN Pharmacology
1. 1) A nurse is caring for a patient with hyperparathyroidism and notes
that the patient's serum calcium level is 13 mg/dL. Which medication
should the nurse prepare to administer as prescribed to the patient?
1. Calcium chloride
2. Calcium gluconate
3. Calcitonin (Miacalcin)
4. Large doses of vitamin D: 3. Calcitonin
(Miacalcin) ELABORATION:
The normal serum calcium level is 8.6 to 10.0 mg/dL. This patient 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. 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 ELABORATION:
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. 3.) Salicylic acid is prescribed for a patient with a diagnosis of psoriasis. The
nurse monitors the patient, knowing that which of the following would indicate
,the presence of systemic toxicity from this medication?
1. Tinnitus
2. Diarrhea
3. Constipation
4. Decreased respirations: 1.
Tinnitus ELABORATION:
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. 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 the sun
3. Immediately before exposure to the sun
4. At least 30 minutes before exposure to the sun: 4. At least 30 minutes
before exposure to the sun
ELABORATION:
Sunscreens are most effective when applied at least 30 minutes before exposure
to the sun so that they can penetrate the skin. All sunscreens should be reapplied
after swimming or sweating.
5. 5.) Mafenide acetate (Sulfamylon) is prescribed for the patient with a burn
in- jury. When applying the medication, the patient complains of local
discomfort and burning. Which of the following is the most appropriate
nursing action?
1. Notifying the registered nurse
2. Discontinuing the medication
3. Informing the patient that this is normal
4. Applying a thinner film than prescribed to the burn site: 3. Informing the
patient that this is normal
ELABORATION:
Mafenide acetate is bacteriostatic for gram-negative and gram-positive organisms
and is used to treat burns to reduce bacteria present in avascular tissues. The
patient should be informed that the medication will cause local discomfort and
burning and that this is a normal reaction; therefore options 1, 2, and 4 are
incorrect
6. 6.) The burn patient is receiving treatments of topical mafenide acetate
(Sulfamylon) to the site of injury. The nurse monitors the patient, knowing
that which of the following indicates that a systemic effect has occurred?
1. Hyperventilation
2. Elevated blood pressure
3. Local pain at the burn
site
4. Local rash at the burn site:
1. Hyperventilation ELABORATION:
Mafenide acetate is a carbonic anhydrase inhibitor and can suppress renal excre-
tion of acid, thereby causing acidosis. Patients receiving this treatment should be
monitored for signs of an acid-base imbalance (hyperventilation). If this occurs, the
, medication should be discontinued for 1 to 2 days. Options 3 and 4 describe local
rather than systemic effects. An elevated blood pressure may be expected from
the pain that occurs with a burn injury.
