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 A
Explanation
A. Apply 4 to 5 ml of liquid soap to the hands: This is the correct action. Applying an adequate amount of soap ensures effective cleaning of the hands. The recommended amount is typically 3 to 5 ml or enough to cover the entire surface of the hands.
B. Hold the hands higher than the elbows: This is incorrect. When performing hand hygiene, the hands should be held lower than the elbows to prevent water from running down the arms and contaminating previously cleaned areas.
C. Rub hands and arms to dry: This is incorrect. After washing the hands, they should be dried using a clean paper towel or air dryer. Rubbing hands and arms to dry is not recommended as it can lead to friction and potential skin irritation.
D. Adjust the water temperature to feel hot: This is incorrect. The water temperature should be warm, not hot, to prevent skin damage or discomfort. Hot water can strip the skin of its natural oils and lead to dryness or irritation.
Correct Answer is D
Explanation
A. Battery involves the unauthorized or harmful touching of another person without their consent. Restraint without proper justification could potentially lead to a charge of battery, but the situation described does not involve actual physical contact.
B. Assault involves the threat of bodily harm to another person, creating fear or apprehension that the harm will be carried out. While the threat of restraint might cause fear, actual restraint is necessary to constitute assault.
C. Invasion of privacy refers to the unauthorized intrusion into an individual's private affairs or the public disclosure of private information. It does not apply to the act of physically restraining a client.
D. False imprisonment occurs when an individual is unlawfully restrained or confined against their will. In this scenario, the provider's directive to restrain the client against her wishes constitutes false imprisonment if the restraint is not justified by the client's medical condition or pose an immediate danger to herself or others.
