A nurse is caring for a 1-month-old infant who weighs 3500 g and is prescribed a dose of cephazolin 50 mg/kg by intermittent IV bolus three times daily. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["175"]
We are asked to calculate the dosage of cephazolin for a 1-month-old infant based on their weight.
Steps to solve: 1. Identify the given values:
- Dose per kg = 50 mg/kg
- Weight of the infant = 3500 g
2. Set up the formula: Dosage (mg) = Dose per kg (mg/kg) × Weight (kg)
3. Since the weight is given in grams, convert it to kilograms: 3500 g / 1000 g/kg = 3.5 kg
4. Substitute the known values into the formula and calculate: Dosage (mg) = 50 mg/kg × 3.5 kg Dosage (mg) = 175 mg
5. Round the answer to the nearest tenth: Dosage (mg) = 175.0 mg
The nurse should administer 175.0 mg of cephazolin per dose.

Correct Answer is B
Explanation
Rationale:
A) Administer ibuprofen as needed for pain: Ibuprofen is not typically recommended for pain relief in infants under 6 months old due to the risk of adverse effects, such as gastrointestinal irritation and renal impairment. Additionally, surgical repair of a cleft lip is not typically associated with severe postoperative pain requiring ibuprofen in infants.
B) Encourage the parents to rock the infant: This is the correct intervention. Rocking or gentle movement can provide comfort to infants postoperatively and may help soothe them. It can also promote bonding between the infant and parents, which is important for emotional support during the recovery period.
C) Offer the infant a pacifier: Pacifiers can be soothing for infants and may help provide non-nutritive sucking comfort. However, it's essential to ensure that the pacifier does not interfere with wound healing or exacerbate discomfort related to the cleft lip repair. Therefore, while offering a pacifier may be appropriate, it should be done with caution and under the guidance of the surgical team.
D) Position the infant on her abdomen: Placing the infant on her abdomen (prone position) is not recommended postoperatively, especially after cleft lip repair surgery. The supine position is typically preferred to reduce the risk of aspiration and ensure adequate airway patency. Additionally, the prone position may put pressure on the surgical site and cause discomfort.
Correct Answer is B
Explanation
A. "I will tell your family of your concern so that they can be here." This option involves the family in the client's care, which is important during end-of-life situations. However, it assumes that the client's primary concern is about the family's presence rather than exploring the underlying emotions or fears the client may be experiencing. While involving the family is beneficial, it may not directly address the client's emotional needs.
B. "I wonder if you are fearful of dying alone." This response demonstrates therapeutic communication by acknowledging the client's statement and exploring the underlying feelings or concerns behind it. It shows empathy and provides an opportunity for the client to express their emotions. Fear of dying alone is a common concern for many individuals facing the end of life, and addressing this fear can help alleviate distress.
C. "We will call your family in time for them to get here." While involving the family is important, this response primarily focuses on the logistics of family arrival rather than addressing the client's emotional needs. It may not fully explore or validate the client's feelings about dying alone.
D. "I will make sure a staff member is in your room at all times." While providing support and ensuring the client's comfort is essential, this response does not directly address the client's emotional needs or explore their concerns about dying alone. It also may not be feasible to have a staff member constantly present in the room. This option may not fully address the client's underlying fears or emotions related to dying alone.
