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
A patient with diabetes has a new prescription for the ACE inhibitor lisinopril. She questions this order because her physician has never told her that she has hypertension. What is the best explanation for this order?
Correct Answer: D
Rationale: The correct explanation for the prescription of the ACE inhibitor lisinopril for a patient with diabetes who does not have hypertension is that this medication has cardioprotective properties. ACE inhibitors, such as lisinopril, have been shown to have beneficial effects beyond just lowering blood pressure. They have been found to reduce the risk of cardiovascular events and complications in patients with diabetes, even in the absence of hypertension. Therefore, the prescription of lisinopril for a patient with diabetes may be for its cardioprotective properties rather than for hypertension control.
Question 3 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 4 of 5
The nurse is preparing to transfuse a patient with a unit of packed red blood cells (PRBCs). Which patient would be best treated with this transfusion?
Correct Answer: B
Rationale: Packed red blood cells (PRBCs) are typically transfused to patients with severe anemia, where the oxygen-carrying capacity of the blood is significantly reduced. PRBCs are concentrated units of red blood cells that can quickly increase the blood's oxygen-carrying capacity. Patients with severe anemia may experience symptoms such as fatigue, weakness, shortness of breath, and pale skin. Transfusion of PRBCs helps to improve oxygen delivery to tissues and organs, alleviating these symptoms and improving the patient's overall well-being.
Question 5 of 5
A patient arrives in the emergency department with severe chest pain. The patient reports that the pain has been occurring off and on for a week now. Which assessment finding would indicate the need for cautious use of nitrates and nitrites?
Correct Answer: A
Rationale: A patient arriving in the emergency department with severe chest pain and a history of episodic chest pain over the past week may be experiencing a myocardial infarction or other serious cardiac event. Nitrates and nitrites are commonly used to manage chest pain in such situations because they help dilate blood vessels, improve blood flow to the heart, and reduce the workload on the heart.
