Chapter 30 : Medications Questions
Question 1 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 2 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 3 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.
Question 4 of 5
Metoprolol 25 mg PO is prescribed. Metoprolol is available as 50-mg tablets. How many tablets would the nurse administer?
Correct Answer: A
Rationale:
To calculate the number of tablets: 25 mg prescribed / 50 mg per tablet = 0.5 tablets.
Question 5 of 5
Phenytoin 100 mg PO is prescribed to be given through a nasogastric tube. Phenytoin is available as 30 mg/5 mL. How much would the nurse administer?
Correct Answer: A
Rationale:
To calculate the volume: 100 mg prescribed / 30 mg per 5 mL = (100/30) * 5 = 16.67 mL.
