A nurse is reinforcing teaching with a client about smoking cessation.

Which of the following client statements indicates an understanding of the teaching?

Answer: B. Stiff posture

Rationale:
A. Lip-smacking : Lip-smacking is not typically an indication of pain in newborns. It may be associated with hunger or neurological responses, but it does not directly indicate discomfort or pain caused by shoulder dystocia or other injuries.
B. Stiff posture : A stiff posture can indicate pain in newborns, as they often exhibit hypertonicity or rigidity when experiencing discomfort. This response is a protective mechanism and may suggest the newborn is reacting to pain from potential nerve or tissue damage caused by shoulder dystocia.
C. Weak cry : While a weak cry may indicate neurological or respiratory distress, it is not a specific sign of pain. In the context of shoulder dystocia, a weak cry could reflect complications such as brachial plexus injury but does not directly signify the presence of pain.
D. Tongue-darting : Tongue-darting is more commonly associated with neurological issues or feeding difficulties rather than pain. It is not a typical behavioral response to discomfort or injury in newborns experiencing complications like shoulder dystocia.

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 The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.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