Chapter 30 : Medications Questions
Question 1 of 5
A nurse in a pediatric practice teaches the mother of a toddler to administer antibiotic ear drops. What education by the nurse is correct?
Correct Answer: C
Rationale: For children ages 3 years and younger, the nurse teaches the parent or caregiver to pull the pinna down and back to straighten the auditory canal, then instill the medication. For adults, the pinna is pulled up and back; for school-age children, the pinna is pulled straight back. The nurse does not insert cotton swabs in the ear; rather, the nurse can wipe the external ear of drainage, if necessary.
Question 2 of 5
A nurse is planning to administer digoxin to a patient. After reviewing the medical record, what action will the nurse take? Electronic Health Record Prescriptions - 11/22/2025 digoxin loading dose 0.25 mg IV twice today only - 11/23/2025 begin digoxin 0.125 mg orally daily Laboratory Studies - Digoxin level: 2.7 ng/mL (reference range 0.5-2 ng/mL)
Correct Answer: B
Rationale: The nurse is responsible for safe medication administration, including interpreting therapeutic serum drug levels. The nurse withholds the medication based on the toxic (high) drug level. Next, the nurse collaborates with the health care provider to determine if a dose adjustment is indicated. Prescribing is outside the nurse's scope of practice; determining a half dose is needed is a prescription. The patient's renal function will be evaluated periodically, but it is most important not to give a medication when the blood level demonstrates toxicity.
Question 3 of 5
A nurse notices that an older adult patient is malnourished, and blood tests reveal reduced plasma protein levels. For which of these pharmacodynamic effects will the nurse observe?
Correct Answer: A
Rationale: Lowered protein levels in the body means less drug bound to plasma proteins, which leads to a higher concentration of free (unbound) drug in the body. This higher drug concentration increases the risk for adverse effects.
Question 4 of 5
A nurse on a medical-surgical unit is planning to administer an antibiotic to a patient with a kidney infection who is 10 weeks' pregnant. The drug reference states that the medication is teratogenic. Which action will the nurse take?
Correct Answer: B
Rationale: Medications that are identified as teratogenic have the potential to cause developmental defects in the embryo or fetus and are contraindicated. The nurse must hold the medication and notify the health care provider of the pregnant person's pregnancy status. The patient is not the best person to determine the impact of this medication on the fetus; the medication is a teratogen, even with dose reduction.
Question 5 of 5
At 8 AM, a nurse receives a prescription for an analgesic to be administered every 4 hours PRN. The nurse plans to administer this medication at what times?
Correct Answer: D
Rationale: When administering PRN medication, the patient receives medication when it is requested or required, and when the clinical parameters of the order, including timing between doses, are met. PRN orders are commonly written for the treatment of symptoms, in this instance, pain.
