Which condition(s) would cause the nurse to hold a PRN order for magnesium hydroxide (Milk of Magnesia)?

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.

Choice A reason:
Nonadherence to the antiviral regimen could result in suboptimal control of the HIV infection, but it is not typically associated with symptoms of increased hunger, thirst, and frequent urination. Therefore, this choice does not explain the patient's symptoms.
Choice B reason:
An allergic reaction might cause a variety of symptoms, such as rash, itching, or swelling, but it would not typically cause increased hunger, thirst, and frequent urination. This choice is incorrect as it does not align with the presented symptoms.
Choice C reason:
Pancreatic infiltration by HIV is a rare and serious condition that can lead to various metabolic complications, but it is not a common cause of the specific symptoms described (increased hunger, thirst, and frequent urination). This choice is not consistent with the patient's symptoms.
Choice D reason:
Hyperglycemia, or high blood sugar, can cause symptoms like increased hunger, thirst, and frequent urination. These symptoms are indicative of diabetes, which can be a side effect of some antiviral medications, particularly protease inhibitors used in HIV treatment. Therefore, this choice accurately reflects the patient's symptoms and is the correct answer.
