A client with symptoms of influenza that started the previous day asks the clinic nurse about taking oseltamivir to treat the infection.
Which response should the nurse provide?

Explain to the client that antibiotics are not useful in treating viral infections such as influenza.

Advise the client that once symptoms occur it is too late to receive an influenza vaccination.

Refer the client to the healthcare provider at the clinic to obtain a medication prescription.

Instruct the client that over-the-counter medications are sufficient to manage influenza symptoms.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

It is true that antibiotics are not effective against viruses like influenza. They only work against bacteria.

However, while providing this information to the client is accurate, it does not directly address the client's inquiry about taking oseltamivir, which is an antiviral medication.

It's essential for the nurse to guide the client toward the appropriate healthcare provider who can assess the client's condition and make an informed decision about whether oseltamivir is a suitable treatment option.

Choice B rationale:

While it is true that influenza vaccination is most effective when given before exposure to the virus, it is still a relevant consideration even after symptoms have begun.

Studies have shown that antiviral medications like oseltamivir can potentially reduce the severity and duration of influenza symptoms, even when started within 48 hours of symptom onset.

Therefore, simply advising the client that it's too late for vaccination without exploring other potential treatment options would be incomplete and potentially disadvantageous to the client's care.

Choice C rationale:

This is the most appropriate response because it ensures that the client receives a comprehensive assessment and individualized treatment plan from a qualified healthcare provider.

The provider can evaluate the client's symptoms, medical history, and potential risk factors to determine if oseltamivir is a suitable medication.

Additionally, the provider can discuss other potential treatment options, such as over-the-counter medications for symptom relief, and provide guidance on self-care measures to promote recovery.

Choice D rationale:

While over-the-counter medications can help manage some symptoms of influenza, such as fever, aches, and cough, they do not directly target the virus itself.

Antiviral medications like oseltamivir can potentially shorten the duration of the illness and reduce the risk of complications, especially in individuals at higher risk.

Therefore, relying solely on over-the-counter medications without considering antiviral therapy could potentially delay recovery and increase the likelihood of adverse outcomes.

Correct Answer is D

Explanation

Choice A rationale:

Observing the skin for lesions is not a specific technique for assessing early signs of rheumatoid arthritis. While RA can sometimes manifest with skin lesions, they are not typically present in the early stages of the disease. Moreover, skin lesions can be indicative of a wide range of other conditions, making them a less reliable indicator of RA.

Choice B rationale:

Palpating the lymph nodes is also not a specific technique for assessing early signs of rheumatoid arthritis. Lymph node enlargement can occur in various inflammatory conditions, including infections and autoimmune diseases. It is not a characteristic feature of early RA.

Choice C rationale:

Palpating large joints for nodules is a technique used to assess for rheumatoid arthritis, but it is more likely to detect nodules in later stages of the disease. Nodules are typically firm, non-tender bumps that develop under the skin around joints. They are often found in areas like the elbows, knuckles, and fingers. However, they may not be present in the early stages of RA.

Choice D rationale:

Observing the client's fingers is the most appropriate technique for assessing early signs of rheumatoid arthritis. This is because the fingers are often the first joints to be affected by the disease. Early signs of RA in the fingers can include:

Swelling of the finger joints, particularly the proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints. Tenderness and pain in the finger joints, especially upon movement.

Stiffness in the finger joints, which is often worse in the mornings and after periods of inactivity. Redness or warmth in the finger joints.

Difficulty bending or straightening the fingers.

A. Proliferation of suppressor T-cells. B. Deficiency of cytotoxic T-cells. C. Increase in B-lymphocytes and IgM. D. Destruction of helper T-cells and CD4 cells.

Correct Answer is D

Explanation

Choice A rationale:

Incorrect. Suppressor T-cells (also known as regulatory T-cells) play a role in regulating the immune response, but their proliferation is not the primary mechanism by which HIV suppresses the immune system. In fact, HIV can disrupt the function of suppressor T-cells, leading to an impaired ability to control immune responses.

Choice B rationale:

Incorrect. Cytotoxic T-cells (also known as CD8+ T-cells) are important for killing infected cells, but their deficiency is not the direct cause of immune suppression in HIV. However, HIV can indirectly lead to a deficiency of cytotoxic T-cells by disrupting their production and function.

Choice C rationale:

Incorrect. B-lymphocytes produce antibodies, and IgM is an early antibody produced in response to infection. However, an increase in B-lymphocytes and IgM is not characteristic of HIV infection. In fact, HIV can impair B-cell function, leading to decreased antibody production.

Choice D rationale:

Correct. HIV primarily targets and destroys helper T-cells (also known as CD4+ T-cells). These cells play a crucial role in coordinating the immune response by activating other immune cells, such as cytotoxic T-cells and B-cells. The depletion of helper T-cells leads to a progressive weakening of the immune system, rendering the body vulnerable to opportunistic infections and cancers.

Specific mechanisms of CD4+ T-cell destruction by HIV:

Direct infection and lysis: HIV can directly infect CD4+ T-cells and replicate within them, eventually leading to the death of the infected cells.

CD4+ T-cell apoptosis: HIV can induce programmed cell death (apoptosis) in CD4+ T-cells through various mechanisms, including the activation of pro-apoptotic pathways and the disruption of anti-apoptotic signals.

Immune dysregulation: HIV infection can also dysregulate the immune system, leading to chronic inflammation and immune activation. This can further contribute to CD4+ T-cell depletion and dysfunction.
