ATI Intro to Pharmacology Quizlet Questions
Question 1 of 5
The nurse is caring for a well-known stage actor who has suddenly developed severe stage fright that is preventing him from working. What drug does the nurse suspect will be prescribed for this patient?
Correct Answer: D
Rationale: One of the indications for use of propranolol is prevention of stage fright, which is a sympathetic stress reaction to a particular situation. None of the other options are indicated for this use. The nurse should understand the indications for propranolol to ensure safe and effective administration.
Question 2 of 5
A client is prescribed Colchicine. After taking three doses, the client complains of nausea, vomiting, and loose bowel stools. Which of the following should the client do?
Correct Answer: B
Rationale: Nausea, vomiting, and diarrhea are signs of colchicine toxicity, which can be life-threatening. The client should stop taking the medication and notify the physician immediately. Continuing the medication or adjusting the dose without medical advice can exacerbate the toxicity. Colchicine has a narrow therapeutic index, and close monitoring is required to prevent adverse effects.
Question 3 of 5
Biperiden hydrochloride (Akineton) is added to a list of antiparkinsonian medications that an elderly client is taking. Which of the following instructions made by the nurse that needs further learning?
Correct Answer: C
Rationale: Walking in the morning for direct sunlight is unrelated to the use of biperiden hydrochloride (Akineton) and does not address its side effects or therapeutic effects. Avoiding alcohol and caffeine, managing dry mouth, and increasing fiber and fluid intake are appropriate instructions. Therefore, the statement about sunlight indicates a need for further learning.
Question 4 of 5
A history of which of the following is a contraindication to short-term HRT to prevent menopausal vasomotor symptoms and menopausal vaginitis?
Correct Answer: B
Rationale: Short-term HRT (estrogen ± progestin) relieves menopausal symptoms. Depression isn't a contraindication; HRT may improve mood. Breast cancer is a absolute contraindication due to estrogen's proliferative risk, outweighing benefits. Hysterectomy allows estrogen-only HRT, bronchitis and eczema are unrelated. Breast cancer's link to estrogen drives this restriction, critical for safe hormone use.
Question 5 of 5
Clearance:
Correct Answer: A
Rationale: Clearance (CL = rate of elimination / plasma concentration) is the amount of drug removed per unit time relative to concentration, a true statement defining its calculation. It's constant for first-order kinetics drugs at therapeutic levels, true. Lithium's clearance is moderate, not very high, handled by kidneys, so that's false. Phenytoin's clearance decreases with concentration (zero-order at high doses), not independent, making that false. Clearance isn't inversely proportional to Vd but related via half-life. This definition is essential for dosing regimens, ensuring steady-state maintenance.
