Chapter 23 : Antianginal Drugs Questions
Question 1 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 commonly cause bradycardia due to their effect on slowing heart rate. They do not typically cause nervousness, hypertension, or dry cough (which is more associated with ACE inhibitors).
Question 2 of 5
When teaching a patient who has a new prescription for transdermal nitroglycerin patches, the nurse tells the patient that these patches are most appropriately used for which situation?
Correct Answer: C
Rationale: Transdermal nitroglycerin patches are used for long-term prophylaxis to prevent angina, not for acute chest pain, shortness of breath, or heart rate control during exercise.
Question 3 of 5
The nurse is providing education about the use of sublingual nitroglycerin tablets. She asks the patient, 'What would you do if you experienced chest pain while mowing your yard? You have your bottle of sublingual nitroglycerin with you.' Which actions by the patient are appropriate in this situation? (Select all that apply.)
Correct Answer: A,C,E,G
Rationale: Appropriate actions include stopping activity, sitting or lying down, placing a sublingual tablet under the tongue, calling 911 if pain persists after one tablet, and taking additional tablets every 5 minutes up to three total. The buccal route (gum and cheek) is incorrect, and waiting 30 minutes for three tablets is too long.
Question 4 of 5
A patient with a history of angina will be started on ranolazine. The nurse is reviewing the patient's history and will note potential contraindications to this drug therapy if which condition is present? (Select all that apply.)
Correct Answer: B,E
Rationale: Ranolazine is contraindicated in patients with prolonged QT interval (due to risk of arrhythmias) and decreased liver function (due to hepatic metabolism). Type 2 diabetes, heart failure, and closed-angle glaucoma are not contraindications.
Question 5 of 5
A patient will be receiving metoprolol 5 mg IV push. The medication is available in a strength of 1 mg/mL. Identify how much medication will the nurse draw up for each dose.
Correct Answer: 5 mL
Rationale:
To calculate: 1 mg/1 mL = 5 mg/x mL. Cross-multiply: (1 * x) = (1 * 5); x = 5 mL.
