A nurse is collecting data from a client who has asthma. Which of the following prescribed medications should the nurse administer first for severe wheezing?

Answer: (A) Inject 20 units of air into the vial of NPH insulin.

Rationale:

A) Inject 20 units of air into the vial of NPH insulin:

Injecting air into the vial of NPH insulin is the first step to prevent creating a vacuum, which could make it difficult to withdraw the insulin later. The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.

B) Inject 5 units of air into the vial of regular insulin:

Injecting air into the regular insulin vial is also necessary before withdrawing the insulin, but it should be done after injecting air into the NPH vial. This sequence ensures that no NPH insulin contaminates the regular insulin vial when the nurse withdraws the doses later.

C) Withdraw 20 units of NPH insulin from the vial:

Withdrawing NPH insulin should be done after air is injected into both vials and after the regular insulin has been drawn up. This sequence prevents the mixing of the two types of insulin and ensures accurate dosing, which is crucial for maintaining the correct blood glucose levels.

D) Withdraw 5 units of regular insulin from the vial:

Withdrawing regular insulin is critical to do before the NPH insulin to prevent contamination of the regular insulin with NPH, which could alter the onset and peak times of the regular insulin. However, it should follow the steps of injecting air into both vials, starting with the NPH vial.

When a client with active pulmonary tuberculosis (TB) receives appropriate treatment and their sputum cultures consistently show negative results for Mycobacterium tuberculosis, it indicates that the client is no longer contagious. Negative sputum cultures indicate that the infectious bacteria are no longer present or viable in the respiratory secretions, reducing the risk of transmitting the disease to others.

"You will need an annual TB skin test to see if the infection has returned": While it is important for individuals with a history of TB to undergo periodic screening, such as an annual TB skin test or interferon-gamma release assay (IGRA), to detect latent TB infection or potential reactivation, this response is not specifically related to a client with active pulmonary TB.

"You will take medication to treat your illness for the rest of your life": This response is incorrect because active pulmonary TB is typically treated with a combination of antimicrobial medications for a specific duration, usually ranging from 6 to 9 months. It is not a lifelong treatment.

However, individuals with latent TB infection may require longer-term treatment to prevent the development of active TB disease.

"You can expect the medications to turn your urine a blue-green color": This response is incorrect as medications used to treat TB do not typically cause urine discoloration. Medications such as rifampin can cause various side effects, including orange discoloration of bodily fluids like urine, tears, or sweat, but a blue-green color is not associated with TB medications.
