Chapter 17: Central Nervous System Stimulants Introductory Clinical Pharmacology 12th Edition by Susan M Ford

Introductory Clinical Pharmacology 12th Edition by Susan M Ford 1. The nurse is conducting an ongoing assessment on a client who has received methylphenidate. Which finding would the nurse anticipate if the medication is therapeutic? a. Decreased appetite b. Low blood pressure c. Drowsiness d. Depression Answer: A Rationale: Amphetamines have the ability to suppress appetite, so the client will show a decrease in appetite. The drug action results in high blood pressure, not low blood pressure. The client also experiences wakefulness, not drowsiness. Amphetamines produce a euphoric state, not depression.

The nurse is monitoring a client who is receiving caffeine. The nurse determines the client is experiencing a therapeutic response with which assessment finding? a. Decease in heart rate b. Decrease in urinary output c. Feeling of euphoria and well-being d. Skeletal muscle stimulation Answer: D Rationale: Caffeine leads to skeletal muscle stimulation. Caffeine results in an increase, not decrease, in heart rate. Caffeine is a diuretic and it increases, not decreases, urinary output. Caffeine does not lead to a feeling of euphoria or well-being.

A client who is obese is to start receiving amphetamine as part of the treatment. Which factor should the nurse prioritize in the preadministration assessment? a. Temperature b. Weight c. Blood glucose level d. Arterial blood gas results Answer: B Rationale: Before administering amphetamine as part of obesity treatment, the nurse should record the client's weight. There is no need to record the client's temperature or blood glucose level. Arterial blood gas results are reviewed when a CNS stimulant is prescribed for respiratory depression but not for obesity treatment.

A client has been prescribed benzphetamine. The nurse would question administering this drug if which is noted in the client medical record? a. Drinks coffee at each meal b. Ordered to take at 6 p.m. c. Currently takes an antidepressant d. Drinks several carbonated caffeine beverages each day Answer: C Rationale: The nurse should ensure that benzphetamine, or any other anorexiant, is not taken concurrently with antidepressant medications. The nurse should avoid or decrease the use of coffee, tea, and carbonated beverages containing caffeine. The drug should be taken early in the day, not around dinner time, to avoid insomnia.

A client with narcolepsy has been administered modafinil. Which reaction would the nurse prioritize for intervention? a. Insomnia b. Nausea c. Urinary retention d. Tremors Answer: B Rationale: The nurse should monitor for nausea because it is one of the common adverse reactions associated with analeptics such as modafinil. Insomnia, urinary retention, and tremors are not reactions generally associated with analeptic drugs.
