Question 1 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 2 of 5
Which of the following is an amide type of local anesthetics:
Correct Answer: B
Rationale: Articaine is an amide type of local anesthetic. Local anesthetics can be classified into two main categories: esters and amides. Articaine belongs to the amide group of local anesthetics, along with lidocaine, bupivacaine, and others. Amide local anesthetics tend to have longer duration of action and are less likely to cause allergic reactions compared to ester local anesthetics. In the given choices, Procaine, Amethocaine, and Benzocaine are ester-type local anesthetics, while Cocaine is a unique example of a local anesthetic with mixed properties.
Question 3 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 4 of 5
A prenatal patient tells the nurse that she is not taking vitamins because she heard that vitamins may cause damage to the fetus if she becomes pregnant. What is the nurse's best response?
Correct Answer: C
Rationale: While vitamins are generally beneficial during pregnancy, excessive doses (megadoses) can be harmful, especially in the first trimester. The nurse should emphasize the importance of taking vitamins at recommended levels and avoiding excessive supplementation. Taking extra vitamins (
B) is not advised, and doses above the RDA (
D) should be avoided unless prescribed.
Question 5 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.
