Exam  For ATI Pharmacology Proctored Testing Database (Full Justification for responses) Grade A+

1. A nurse is taking care of a patient with hyperparathyroidism and notices that the patient’s blood calcium level is 13 mg/dL. What medication should the nurse get ready to administer as per the prescription? 1. Calcium chloride 2. Calcium gluconate 3. Calcitonin (Miacalcin) 4. High doses of vitamin D.

2. Oral iron supplements are advised for a 6-year-old child with iron deficiency anemia. The nurse advises the mother to give the iron with which preferable food item? 1. Milk 2. Water 3. Apple juice 4. Orange juice.

3. Salicylic acid is ordered for a patient diagnosed with psoriasis. The nurse supervises the patient, understanding that which of the following would indicate the presence of systemic toxicity from this medication? 1. Tinnitus 2. Diarrhea 3. Constipation 4. Reduced respirations.

4. The camp nurse questions the children about applying sunscreen before swimming in the lake. The nurse reminds the children that chemical sunscreens are most effective when applied: 1. Right before swimming 2. 15 minutes before sun exposure 3. Directly before sun exposure 4. At least 30 minutes before sun exposure.

5. Mafenide acetate (Sulfamylon) is prescribed for a patient with a burn injury. When applying the medication, the patient expresses local discomfort and burning. What is the most appropriate action for the nurse to take? 1. Alerting the registered nurse 2. Halting the medication 3. Informing the patient that this is normal 4. Administering a thinner layer than prescribed to the burn site.

Calcitonin (Miacalcin) Justification: The usual blood calcium level is 8.6 to 10.0 mg/dL. This patient is facing hypercalcemia. Calcium gluconate and calcium chloride are drugs used for tetany treatment, which occurs due to acute hypocalcemia. In hypercalcemia, it is necessary to avoid large doses of vitamin D. Calcitonin, a thyroid hormone, reduces the plasma calcium level by inhibiting bone resorption and decreasing the blood calcium concentration.

Orange juice Justification: Vitamin C enhances the body’s absorption of iron. The mother should be instructed to administer the medication with a citrus fruit or juice high in vitamin C. Milk may impact iron absorption. Water does not aid absorption. Orange juice has more vitamin C than apple juice.

Tinnitus Justification: Salicylic acid is readily absorbed through the skin, leading to systemic toxicity (salicylism). Symptoms include tinnitus, dizziness, increased breathing, and psychological disturbances. Constipation and diarrhea are not related to salicylism.

At least 30 minutes before sun exposure Justification: Sunscreens are most effective when applied at least 30 minutes before sun exposure to penetrate the skin. All sunscreens should be reapplied after swimming or sweating.

Informing the patient that this is normal Justification: Mafenide acetate is bacteriostatic for gram-negative and gram-positive organisms and is used to treat burns by reducing bacteria in avascular tissues. The patient should be informed that the medication may cause local discomfort and burning which is a normal reaction.
