What will the nurse expect when assessing the anterior fontanelle of a healthy, full-term newborn?

A.

Smaller than the posterior fontanelle

B.

Triangular shaped

C.

Open and diamond shaped

D.

Depressed and sunken

Answer and Explanation

The Correct Answer is C

A. Smaller than the posterior fontanelle: The anterior fontanelle is larger than the posterior fontanelle. The anterior fontanelle is typically 2.5 to 4 cm in diameter, while the posterior fontanelle is much smaller, measuring about 0.5 to 1 cm.

B. Triangular shaped: The triangular shape is characteristic of the posterior fontanelle, not the anterior fontanelle.

C. Open and diamond shaped: The anterior fontanelle is normally open at birth and diamond-shaped. It allows for skull flexibility during birth and typically closes between 12 and 18 months of age, indicating normal development.

D. Depressed and sunken: A sunken fontanelle may indicate dehydration or fluid loss. In a healthy full-term newborn, the anterior fontanelle should be flat or slightly concave but not markedly depressed.

Correct Answer is ["200"]

Explanation

Calculation:

Total volume = 100 mL.

Infusion time = 30 minutes

= 30 minutes / 60 minutes/hour

= 0.5 hours.

  • Calculate the infusion rate in milliliters per hour (mL/hr).

Infusion rate (mL/hr) = Total volume (mL) / Total time (hr)

= 100 mL / 0.5 hr

= 200 mL/hr.

Correct Answer is B

Explanation

A. Flex her knee while resting: Bending or flexing the knee can increase venous pressure and potentially worsen a thrombus if a deep vein thrombosis (DVT) is present. This is not recommended until the client is evaluated by a healthcare provider.

B. Elevate her leg: Elevating the affected leg helps reduce swelling and promotes venous return, which can alleviate discomfort. This is a safe supportive measure while awaiting medical evaluation for possible DVT.

C. Apply cold compresses: Cold compresses are typically used for acute inflammation or localized injury, but in suspected DVT, cold therapy does not provide therapeutic benefit and may delay appropriate treatment.

D. Massage the area: Massaging a leg with suspected DVT is contraindicated because it can dislodge a thrombus, increasing the risk of pulmonary embolism. This intervention should be avoided entirely until medical assessment.
