A nurse is collecting data from an 18-month-old toddler at a well-child visit.

Which of the following findings should the nurse report to the provider?

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 The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.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

Placenta previa is a condition where the placenta partially or completely covers the opening of the cervix. One of the hallmark signs of placenta previa is painless vaginal bleeding, typically bright red in color. This bleeding can occur spontaneously or during activities that put pressure on the uterus, such as sexual intercourse or physical exertion.

A rigid abdomen is not typically associated with placenta previa. It may indicate other conditions, such as peritonitis or abdominal muscle rigidity, but it is not a characteristic finding of placenta previa.

Persistent uterine contractions are not typically associated with placenta previa. Placenta previa is more commonly associated with painless bleeding rather than contractions. However, if placenta previa is complicated by other factors, such as placental abruption, contractions and abdominal pain may be present.

Fetal movement is not directly related to placenta previa. Fetal movement can vary from person to person and does not specifically indicate placenta previa. However, it is important for the nurse to assess fetal well-being in clients with placenta previa as bleeding can impact the oxygen supply to the fetus.
