A nurse is discussing intravenous Amphotericin B treatment with a nursing student who is about to care for a patient with a systemic fungal infection. Which statement by the student indicates a need for further teaching?

There is an infusion reaction to Amphotericin B

Infusions of Amphotericin B should be administered rapidly

The IV site should be rotated frequently to reduce the risk of phlebitis or use bigger vein for the treatment like central line

Amphotericin B is for treatment of fungal infection

Answer and Explanation

The Correct Answer is B

Choice A reason:
As mentioned earlier, infusion reactions are common with Amphotericin B, including symptoms like fever and chills. Therefore, recognizing that these reactions occur is correct and indicates a proper understanding of the medication's effects.
Choice B reason:
Rapid administration of Amphotericin B is incorrect because it increases the risk of severe side effects. The infusion should be slow to ensure patient safety, indicating that the student needs further teaching on this point. Thus, this choice is incorrect and suggests a misunderstanding.
Choice C reason:
Frequent rotation of the IV site or the use of a central line is standard practice to minimize the risk of phlebitis. This practice is correct and shows that the student understands how to manage the complications associated with Amphotericin B infusion.
Choice D reason:
Amphotericin B's primary use is to treat systemic fungal infections. This is a correct statement, reflecting an accurate understanding of the drug's purpose and does not require further teaching.

Correct Answer is A

Explanation

Choice A reason:
Stenosis is characterized by the constriction and narrowing of the valve opening, which causes the valve leaflets to fail to open completely. This condition restricts blood flow through the valve, leading to increased pressure in the heart and reduced blood flow to the body or lungs, depending on which valve is affected.

Choice B reason:
Regurgitation refers to the condition where the valve does not close properly, allowing blood to flow backward. This is different from stenosis, where the valve opening is narrowed and does not allow sufficient blood flow forward.

Choice C reason:
Insufficiency is another term for regurgitation and involves the backward flow of blood due to improper closure of the valve. It does not describe the condition where the valve opening is narrowed and restricts forward blood flow.

Choice D reason:
Incompetence also refers to the inability of the valve to close properly, leading to regurgitation. It is not used to describe the narrowing of the valve opening, which is the defining characteristic of stenosis.

A. Replicate their genetic material inside host cells B. Are easily killed by antimicrobials C. Contain no DNA or RNA D. Are capable of independent reproduction

Correct Answer is A

Explanation

Choice A reason:
Viruses are known for their unique replication process. They cannot replicate independently and must hijack a host cell's machinery to reproduce. This characteristic is fundamental to understanding viruses and is a key concept in virology. By replicating their genetic material inside host cells, viruses ensure their propagation and survival. This answer is correct because it highlights this crucial aspect of viral biology.
Choice B reason:
This choice is incorrect because viruses are not easily killed by antimicrobials. Antimicrobials, such as antibiotics, are typically effective against bacteria, not viruses. Viruses have different structures and replication mechanisms that make them resistant to these treatments. Instead, antiviral medications are needed to target viruses specifically.
Choice C reason:
This choice is also incorrect. Viruses do contain either DNA or RNA as their genetic material. This genetic material is essential for their replication and propagation. Some viruses have DNA, while others have RNA, and this distinction is one of the primary ways viruses are classified.
Choice D reason:
Viruses are not capable of independent reproduction. They rely entirely on infecting host cells to replicate. This dependence on host cells distinguishes them from other microorganisms like bacteria, which can reproduce on their own. Thus, this choice is incorrect as it does not accurately reflect the nature of viruses.
