Question 1 of 5
Currently, there is no way to prevent myelosuppression. However, there are medications available to elicit a more rapid bone marrow recovery. An example is:
Correct Answer: A
Rationale: Epoetin alfa (Epogen, Procrit) is an example of a medication used to elicit a more rapid bone marrow recovery. It is a form of erythropoietin, which stimulates the production of red blood cells in the bone marrow. By stimulating red blood cell production, epoetin alfa can help in faster recovery from myelosuppression, a condition characterized by low blood cell counts. This medication is commonly used in patients undergoing chemotherapy or those with chronic kidney disease to manage anemia and improve overall quality of life. Therefore, epoetin alfa is the correct answer in this scenario as it specifically addresses the issue of bone marrow recovery.
Question 2 of 5
The following inhibits cell wall synthesis, except:
Correct Answer: D
Rationale: Nystatin is an antifungal medication that works by disrupting fungal cell membrane function, specifically targeting ergosterol and causing the formation of pores in the cell membrane, leading to cell death in fungi. It does not inhibit cell wall synthesis, unlike the other options listed.
Question 3 of 5
The patient has been prescribed oxymetazoline (Afrin). What medication information should the nurse provide?
Correct Answer: D
Rationale: Oxymetazoline acts fast; adherence prevents rebound . Days is wrong. D ensures safe use, making it key.
Question 4 of 5
What is the most common side effect of insulin?
Correct Answer: B
Rationale: The most common side effect of insulin therapy is hypoglycemia, which occurs when the blood sugar levels drop too low. Insulin helps lower blood sugar levels by promoting the uptake of glucose into cells, but an excessive dose of insulin or changes in diet and physical activity can lead to hypoglycemia. Symptoms of hypoglycemia may include shakiness, sweating, dizziness, confusion, and hunger. It is important for individuals using insulin to be aware of the signs and symptoms of hypoglycemia and be prepared to treat it promptly with fast-acting glucose sources. Regular monitoring of blood sugar levels can help prevent and manage episodes of hypoglycemia.
Question 5 of 5
Which of the following drugs is most effective in converting a patient with atrial fibrillation into sinus rhythm?
Correct Answer: B
Rationale: Converting atrial fibrillation (AF) to sinus rhythm requires cardioversion or antiarrhythmics. Digoxin controls rate, not rhythm, ineffective for conversion. Atenolol, a beta-blocker, and diltiazem, a calcium channel blocker, manage rate, not rhythm restoration. Lidocaine treats ventricular arrhythmias. Amiodarone, a class III antiarrhythmic, prolongs repolarization, effectively converting AF to sinus rhythm, especially in acute settings, outperforming others. Its broad-spectrum action is key in AF management, balancing efficacy and safety.
