Question 1

What specific effect on the heart does a drug with a positive inotropic action have?

Accepted Answer

A drug with a positive inotropic action increases the force of the heart's contractions, leading to an increased pumping action. This means that more blood is ejected from the heart with each beat, improving cardiac output. It does not have a direct effect on heart rate.

Question 2

A woman taking tolterodine for overactive bladder tells you that she now has all the following changes noted below. Which ones will you report to the healthcare provider? (Select all that apply.)

Accepted Answer

Chest pain, irregular heart rate, and swollen ankles are serious side effects that should be reported to a healthcare provider as they may indicate significant cardiovascular issues or other serious conditions.

Question 3

Which symptoms are indicators of digoxin toxicity? (Select all that apply.)

Accepted Answer

Digoxin toxicity can lead to blurred vision, nausea and vomiting, and palpitations as part of its clinical presentation. These symptoms reflect the drug's effects on the cardiovascular and gastrointestinal systems.

Question 4

By which mechanism or mechanisms do the nitrates help angina and heart failure?

Accepted Answer

Nitrates work by dilating blood vessels, which decreases preload (the amount of blood returning to the heart) and decreases afterload (the resistance the heart has to pump against). This decreases the workload on the heart and improves blood flow, which can relieve angina and improve symptoms of heart failure.

You are assessing the knowledge of a patient who has been using nitroglycerine for about a year as needed for angina. Which statement indicates the need for more teaching?

Accepted Answer

Nitroglycerine tablets should be kept in their original container to maintain their potency, not carried in a baggie. The statement in choice C indicates a misunderstanding about the proper storage of the medication, which could affect its effectiveness.

Question 12

Which factor or symptom is used to determine the most effective drug class to manage a patient's cardiac dysrhythmia?

Accepted Answer

The cause of the dysrhythmia is the most important factor in determining the most effective drug class to manage a patient's cardiac dysrhythmia. Different drugs target different pathways or mechanisms that can lead to dysrhythmias. Knowing the cause of the dysrhythmia will help the healthcare provider choose the most appropriate drug to treat it.

Question 13

The patient is prescribed to receive 40 mg of furosemide by IV push at a rate of 10 mg per minute. The vial of furosemide on hand has a concentration of 20 mg/mL.How many total minutes are required to give 40 mL at a rate of 10 mg/minute?

Question 14

Which precautions are most important to teach the caregiver of a home care patient who is prescribed nitroglycerine patches? (Select all that apply.)
