Question 1 of 5.

The home-care nurse is educating the parents of a 1-week-old newborn. Which instruction should the nurse include about the care of the newborn's umbilical cord?

A. “Begin applying rubbing alcohol to the base of the cord stump three times a day.”

B. “Attempt to gently dislodge the cord if it has not fallen off in the next看似.”

C. “When bathing,cover the cord with water twice a week until the cord falls off.”

D. “Continue to place the diaper below the cord when diapering the infant.”

Explanation: Folding the diaper below the cord prevents contact with urine/stool reducing infection risk. Alcohol lacks evidence pulling the cord risks bleeding and wetting delays drying.

Question 2 of 5.

Which finding documented by the nurse is most indicative of a client with rheumatic fever?

A. Slow, irregular heartbeat

B. Blotchy, diffuse erythema

C. Decreased antistreptolysin O titer (ASO titer)

D. Generalized migrating joint tenderness

Explanation: Generalized migrating joint tenderness (polyarthritis) is a hallmark symptom of rheumatic fever, reflecting the inflammatory process affecting multiple joints. An elevated ASO titer (not decreased) would indicate a recent streptococcal infection, and the other options are less specific.

Question 3 of 5.

Which statement by the parents best indicates that the nurse's teaching has been effective?

A. We'll give our child the penicillin for the full 10 days.

B. We will keep our child at home until fully recovered.

C. We will make sure that our child stays out of the sun with being treated.

D. We'll notify the physician if our child has a sore throat.

Explanation: Effective teaching about rheumatic fever emphasizes preventing recurrent streptococcal infections, which can trigger relapse. Notifying the physician about a sore throat ensures prompt treatment of potential streptococcal infections, reducing recurrence risk.

Question 4 of 5.

When is the correct time for the nurse to administer the child's morning dose of a combination regular and NPH insulin?

A. 30 minutes before breakfast is served

B. 15 minutes before breakfast is served

C. 30 minutes after breakfast is served

D. 15 minutes after breakfast is served

Explanation: Regular insulin peaks in 2-4 hours, and NPH peaks in 4-12 hours. Administering the combination 30 minutes before breakfast aligns insulin onset with food intake, controlling postprandial glucose levels effectively.

Question 5 of 5.

Which clinical manifestation of the client's full-thickness burns would the nurse detect during an assessment?

A. Moderate level of pain due to exposed nerve endings

B. Eschar formation throughout the area of the burn

C. The appearance of blister formation throughout the area of the burn

D. Noted tissue destruction extending to the subcutaneous layer

Explanation: Full-thickness burns involve destruction of all skin layers, including the subcutaneous layer, resulting in a leathery or charred appearance. Pain is minimal due to nerve destruction, and blisters are characteristic of partial-thickness burns.
