A young adult calls the clinic to ask for a prescription for a new flu drug.

He says he has had the flu for almost 4 days and just heard about a drug that can reduce the symptoms.

What is the nurse’s best response to his request?

Choice A rationale:

This choice is incorrect. While it’s true that antiviral drugs can be effective in treating the flu, they’re most effective when started within 48 hours of symptom onset. Starting treatment after 4 days may not provide the same benefits.

Choice B rationale:

This choice is incorrect. While a blood test can confirm the presence of the flu virus, it’s not typically necessary to diagnose the flu. Diagnosis is usually based on symptoms and the fact that the flu is widespread in the community.

Choice C rationale:

This choice is correct. Antiviral drugs are most effective when started within 2 days of symptom onset. After this time, the benefits of these drugs decrease. Therefore, starting treatment 4 days after symptoms begin may not significantly reduce the duration or severity of symptoms.

Choice D rationale:

This choice is incorrect. While it’s true that getting a flu vaccine is important, it’s not the best response in this situation. The flu vaccine won’t treat current illness. It’s designed to prevent future infections. In this case, the individual is already sick, so a booster vaccination wouldn’t be the most effective course of action.

Choice A rationale:

Sodium levels in the blood are typically between 135 and 145 milliequivalents per liter (mEq/L). A sodium level of 140 mEq/L falls within this range, indicating normal sodium levels. Sodium plays a key role in your body. It helps maintain normal blood pressure, supports the work of your nerves and muscles, and regulates your body’s fluid balance. A normal sodium level is therefore crucial for the body’s overall function.

Choice B rationale:

A glucose level of 120 mg/dL is considered normal for a fasting blood sugar test. Glucose is your body’s main source of energy. It comes from the food you eat and is carried through your bloodstream to the cells of your body. If the glucose level in the blood is too high or too low, it can indicate a medical condition such as diabetes.

Choice C rationale:

Potassium levels in the blood are typically between 3.6 and 5.2 millimoles per liter (mmol/L). A potassium level of 4.5 mEq/L falls within this range, indicating normal potassium levels. Potassium is a type of electrolyte that is vital to the function of nerve and muscle cells, including those in your heart. Your blood potassium level is normally 3.6 to 5.2 millimoles per liter (mmol/L). Having a blood potassium level higher than 6.0 mmol/L can be dangerous and usually requires immediate treatment.

Choice D rationale:

The Blood Urea Nitrogen (BUN) test is a routine test used to assess kidney function. Urea nitrogen is a waste product that’s created in your liver when the body breaks down proteins. Healthy kidneys filter urea nitrogen from your blood, but when your kidneys aren’t working well, the BUN level rises. The normal range for BUN is typically around 7-20 mg/dL2. A BUN level of 55 mg/dL is significantly higher than the normal range, indicating that the kidneys may not be functioning properly. This is a critical finding that should be reported to the provider before initiating the medication amphotericin B. Amphotericin B is an antifungal medication used to treat serious, life-threatening fungal infections. However, it is known for its severe and potentially lethal side effects, including kidney damage. Therefore, a high BUN level should be reported to the provider before initiating this medication.
