A nurse is collecting data from a 6-week-old infant. Which of the following findings should the nurse expect?

A.

Absence of Babinski reflex

B.

Absence of Moro reflex

C.

Closure of the posterior fontanel

D.

Closure of the anterior fontanel

Answer and Explanation

The Correct Answer is C

A. Absence of Babinski reflex: The Babinski reflex (a fanning of the toes when the sole of the foot is stroked) is normal in infants and should be present until around 12 months of age. Its absence at 6 weeks would be atypical.
B. Absence of Moro reflex: The Moro reflex (a startle response) is typically present in newborns and may begin to disappear by 3-6 months of age. Its absence at 6 weeks would be concerning and could indicate neurological issues.
C. Closure of the posterior fontanel: The posterior fontanel typically closes by 6-8 weeks of age. This is a normal finding for a 6-week-old infant.
D. Closure of the anterior fontanel: The anterior fontanel typically closes between 12 and 18 months of age, not by 6 weeks. Therefore, closure of the anterior fontanel at 6 weeks would be unusual.

Correct Answer is C

Explanation

A. “I’m guessing your other parent did not do anything to stop this from happening.”
This statement makes assumptions about the other parent's actions and could lead to further conflict or discomfort for the adolescent. It’s important to avoid making judgments and focus on providing support.
B. “Your parent was wrong to hit you for coming home late.” This statement may come across as judgmental or accusatory, which could hinder communication and trust with the adolescent. It's important to validate their feelings first and address the situation appropriately.
C. “It is not your fault that this happened to you.” This response is empathetic and supportive. It reassures the adolescent, which is an important step in helping them feel safe and understood. It also provides an opportunity for further discussion about their safety.
D. “I won’t tell anyone else about this unless you say it’s okay.” While privacy is important, this could be misleading. In cases of abuse, the nurse is required to report the situation to protect the adolescent, even if they don't consent.

Correct Answer is ["8"]

Explanation

Calculation:

  • Calculate the desired dose in milligrams (mg) per administration.

Desired dose (mg) = 4 mg/kg × 16 kg

= 64 mg.

Available concentration of the medication = 40 mg/5 mL.

  • Calculate the volume in milliliters (mL) to administer per dose.

Volume (mL) = Desired dose (mg) / (Available concentration (mg) / Available volume (mL))

= 64 mg / (40 mg / 5 mL)

= 8 mL.
