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
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 is in an urgent care center and is receiving treatment for mild hyponatremia after spending several hours doing gardening work in the heat of the day. The nurse expects that which drug therapy will be used to treat this condition?
Correct Answer: B
Rationale: In the scenario described, the patient is experiencing hyponatremia, a condition where there is an imbalance of electrolytes in the body due to excess water intake or loss of sodium-rich fluids like sweat. In this case, the patient has developed mild hyponatremia likely due to the combination of gardening work and exposure to heat.
Question 4 of 5
When administering the anticoagulant drug Warfarin, what is one of the two lab tests you should monitor to distinguish the effectiveness of the drug?
Correct Answer: B
Rationale: When administering the anticoagulant drug Warfarin, one of the two lab tests you should monitor to distinguish the effectiveness of the drug is the International Normalized Ratio (INR). INR measures the time it takes for blood to clot and is used to monitor the effects of Warfarin therapy. The target INR range for patients on Warfarin therapy varies depending on the indication for treatment, but in general, a higher INR indicates that the blood is taking longer to clot, which means the Warfarin is working effectively to prevent blood clots. Regular monitoring of the INR levels is essential to ensure that patients are receiving an appropriate dose of Warfarin to prevent both clotting and bleeding complications.
Question 5 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.
