ATI Intro to Pharmacology Quizlet Questions
Question 1 of 5
The nurse administers atenolol (Tenormin) to a client with hypertension. Which finding would prompt the nurse to hold the dose and notify the physician?
Correct Answer: B
Rationale: Atenolol, a beta-blocker, lowers blood pressure and heart rate by blocking sympathetic stimulation. A heart rate of 52 bpm is bradycardic (below 60 bpm), a threshold for holding beta-blockers due to risk of inadequate perfusion, especially in hypertension where cardiac output matters. Holding and notifying the physician prevents harm, allowing reassessment. BP of 130/80 is controlled, not urgent. Respiratory rate of 18 and temperature of 98.6°F are normal. Atenolol's selectivity for beta-1 receptors makes bradycardia a key adverse effect, requiring vigilance. This action aligns with nursing protocols for beta-blockers, prioritizing cardiovascular stability, making B the finding warranting immediate intervention.
Question 2 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 3 of 5
A patient taking SMZ/TMP asks the nurse what the name means. The nurse replies sulfamethoxazole is combined with trimethoprim in SMZ/TMP to help the drug effectiveness. How does this work?
Correct Answer: D
Rationale: SMZ/TMP (sulfamethoxazole/trimethoprim) works synergistically to inhibit bacterial folate synthesis at two different steps, making it effective against a broad spectrum of gram-positive and gram-negative organisms. It does not act as an anesthetic (A), displace trimethoprim (B), or increase excretion in the bladder (C). The combination enhances antibacterial activity and reduces the risk of resistance.
Question 4 of 5
While assessing a patient who is taking a beta blocker for angina, the nurse knows to monitor for which adverse effect?
Correct Answer: C
Rationale: Beta blockers work by blocking the action of beta-adrenergic receptors, resulting in a decreased heart rate. Bradycardia is a known adverse effect of beta blockers, and it is important for the nurse to monitor the patient's heart rate regularly while taking this medication, particularly for individuals with pre-existing heart conditions. Nervousness, hypertension, and dry cough are not typically associated with beta blocker use.
Question 5 of 5
A 48-year-old woman with obsessive-compulsive disorder presents to her primary care physician for evaluation. She states that her symptoms have worsened during the last 6 months and desires treatment. She has begun on sertraline. Which of the following precautions must be exercised by the physician?
Correct Answer: D
Rationale: Sertraline, an SSRI, risks suicidal tendencies , especially early in treatment for OCD. Hepatic carcinoma , volume overload , and antibiotic potentiation aren't concerns. FDA warnings highlight this risk, necessitating monitoring in this worsening case.
