A nurse is reinforcing teaching with a parent about appropriate snacks for a toddler. Which of the following foods should the nurse include?

Answer: D

Rationale:

A) Collect 2 mL of sputum in an emesis basin: Collecting sputum in an emesis basin is inappropriate for laboratory testing. The sputum should be collected directly into a sterile container to prevent contamination. This ensures that the culture and sensitivity results are accurate and reflect the client's true respiratory pathogens.

B) Instruct the client to rinse with an antiseptic mouthwash prior to specimen collection: Using an antiseptic mouthwash before collecting a sputum sample is not recommended because it may alter the flora present in the sputum, leading to inaccurate culture results. Instead, the client should rinse their mouth with plain water to clear excess saliva or food debris.

C) Swab the oropharynx with a sterile swab: Swabbing the oropharynx does not obtain sputum from the lungs but instead gathers a sample from the throat, which may not be reflective of lower respiratory infections. A proper sputum sample is produced through a deep cough to collect material directly from the lungs.

D) Refrigerate the specimen until the time of transport to the laboratory: Refrigerating the sputum specimen helps to preserve its integrity by preventing the overgrowth of bacteria or other pathogens until it can be transported to the laboratory. Proper refrigeration ensures that the culture and sensitivity results remain accurate.

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 The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.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.
