Question 1 of 5
Which drug classes are considered first-line treatment for heart failure? (Select all that apply.)
Correct Answer: A
Rationale: The drug classes considered first-line treatments for heart failure include Angiotensin-converting enzyme (ACE) inhibitors, Angiotensin II receptor blockers (ARBs), and Beta blockers.
Question 2 of 5
Glyceryl trinitrate for angina is most effective when given in what route?
Correct Answer: D
Rationale: Glyceryl trinitrate, also known as nitroglycerin, is most effective for the treatment of angina when given sublingually (under the tongue). This route allows for rapid absorption of the medication directly into the bloodstream, providing quick relief of angina symptoms. Sublingual administration ensures the drug bypasses the first-pass metabolism in the liver, resulting in higher bioavailability compared to oral administration. The sublingual route also allows for a faster onset of action, making it the preferred route for the management of acute angina episodes.
Question 3 of 5
A patient has received an IV dose of adenosine, and almost immediately the heart monitor shows
Correct Answer: D
Rationale: Adenosine is a medication commonly used to treat certain types of irregular heartbeats, such as supraventricular tachycardia. One of the common side effects of adenosine administration is transient asystole or a brief pause in the electrical activity of the heart. This can cause the heart to stop beating momentarily, leading to a drop in blood pressure and a feeling of lightheadedness in the patient.
Therefore, in this scenario where the heart monitor shows an immediate abnormality after adenosine administration, the nurse should prepare to administer cardiopulmonary resuscitation and be ready to intervene if the patient's heart rhythm deteriorates further. It is crucial to be proactive and prepared to respond quickly to any adverse effects of the medication to prevent potential harm to the patient. Regular monitoring should also continue to assess the patient's condition and response to treatment.
Question 4 of 5
When starting a patient on antidysrhythmic therapy, the nurse will remember that which problem is a potential adverse effect of any antidysrhythmic drug?
Correct Answer: D
Rationale: While it may seem counterintuitive that starting a patient on antidysrhythmic therapy could potentially cause dysrhythmias, it is important to remember that antidysrhythmic drugs can have proarrhythmic effects. Proarrhythmia refers to the development of new or more severe dysrhythmias as a result of the medication intended to treat dysrhythmias. This can occur due to various mechanisms, such as altering the electrical conduction system of the heart or disrupting the normal rhythm.
Therefore, dysrhythmias are a potential adverse effect that the nurse should monitor for when initiating antidysrhythmic therapy in a patient. It is crucial for the healthcare team to closely monitor the patient's cardiac rhythm and adjust the medication regimen as needed to minimize the risk of proarrhythmia.
Question 5 of 5
The nurse is caring for a patient with colorectal cancer who is to receive fluorouracil. Which symptom will be most important for the nurse to report to the health care provider?
Correct Answer: C
Rationale: Fluorouracil, an antimetabolite chemotherapy drug, can cause myelosuppression, leading to a decrease in platelets (thrombocytopenia). Bleeding gums is a sign of low platelet counts and potential bleeding risk, which can be life-threatening if not addressed promptly. Nausea, decreased appetite, and constipation are common side effects of chemotherapy but are not as urgent as bleeding gums, which indicates a potential hematologic emergency. The nurse should report this symptom immediately to the healthcare provider for further evaluation and intervention, such as platelet transfusion or dose adjustment.
