Question 1 of 5
Which of the following are possible mechanisms for the bactericidal/bacteriostatic effects of antiseptics and disinfectants?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
The nurse frequently administers propranolol (Inderal) as treatment for what condition?
Correct Answer: B
Rationale: The beta-adrenergic blocking agents are used to treat cardiovascular problems (hypertension, angina, migraine headaches) and to prevent reinfarction after MI. The prototype drug, propranolol, was in fact the most prescribed drug in the country in the 1980s and is still considered a first-line drug. Propranolol does not prevent first MIs and it is not used for hypotension or cluster headaches. The nurse should understand the indications for propranolol to ensure safe and effective administration.
Question 3 of 5
A patient diagnosed with alcoholism has questions about his medications. The nurse correctly explains that alcoholism can be associated with deficiency of which vitamin?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Myeloablation using chemotherapeutic agents is useful in cancer treatment because:
Correct Answer: D
Rationale: Myeloablation refers to the destruction of bone marrow, which is a critical step in preparing a patient for a bone marrow or stem cell transplant. This process eliminates both cancerous and healthy bone marrow cells, creating space for the transplanted cells to engraft and repopulate the marrow. While myeloablation can reduce tumor size, its primary purpose is to prepare the body for transplantation. It is not related to destroying muscle cells or reducing postoperative chemotherapy requirements.
Question 5 of 5
Combination chemotherapy is used in the treatment of cancer because:
Correct Answer: A
Rationale: Combination chemotherapy is used to target cancer cells through multiple mechanisms, reducing the likelihood of resistance. Single-agent therapy often leads to the development of resistant cell lines, as cancer cells can adapt to the drug. By using a combination of drugs with different mechanisms of action, the treatment can more effectively kill cancer cells and prevent resistance. While two drugs may increase efficacy, the primary rationale is to overcome resistance. Larger doses of single agents are not the main reason for combination therapy.
