Chapter 23 : Antianginal Drugs Questions
Question 1 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 2 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.
Question 3 of 5
When the nurse is administering topical nitroglycerin ointment, which technique is correct?
Correct Answer: C
Rationale: Removing old nitroglycerin ointment before applying a new dose ensures proper dosing and prevents accumulation. The ointment should be applied to the upper arms or body, not massaged, and is used for prophylaxis, not acute angina treatment.
Question 4 of 5
The nurse is giving intravenous nitroglycerin to a patient who has just been admitted because of an acute myocardial infarction. Which statement is true regarding the administration of the intravenous form of this medication?
Correct Answer: D
Rationale: Non-PVC bags and tubing are required for IV nitroglycerin to prevent drug absorption or decomposition. The solution should be clear, not colored, and is given via infusion, not bolus, and not mixed with other medications.
Question 5 of 5
A patient has been diagnosed with angina and will be given a prescription for sublingual nitroglycerin tablets. When teaching the patient how to use sublingual nitroglycerin, the nurse will include which instruction?
Correct Answer: C
Rationale: Current guidelines advise calling 911 if chest pain persists 5 minutes after one sublingual nitroglycerin tablet, as it may indicate a myocardial infarction. Additional tablets can be taken every 5 minutes up to three total, and tablets should dissolve under the tongue, not be chewed.
