A child weighs 6 lbs and is to receive Ampicillin 50 mg/kg/24 hrs and then it’s divided into q hr doses.
How many mg will he receive with each dose?
90 mg
60 mg
36 mg
290 mg .
The Correct Answer is C
The correct answer is Choice C.
Step 1: Convert the child’s weight from lbs to kg.
Since 1 lb is approximately 0.45 kg, a child who weighs 6 lbs weighs approximately 2.72 kg (6 lbs × 0.45 =2.72 kg). Step 2: Calculate the total daily dose of Ampicillin. The total daily dose is 50 mg/kg/day, so for a child who weighs 2.72 kg, the total daily dose would be approximately 136 mg (50 mg/kg/day × 2.72 kg = 136 mg/day). Step 3: Since the total daily dose is divided into q hr doses (4 doses per day), each dose would be approximately 34 mg (136 mg/day ÷ 4 doses/day = 34 mg/dose). So, the child will receive approximately 34 mg of Ampicillin with each dose.

Correct Answer is A
Explanation
Choice A rationale:
Weighing the infant every day on the same scale at the same time is crucial in monitoring excess fluid volume in congestive heart failure. Sudden weight gain can indicate fluid retention, a common sign of worsening heart failure. Daily weight monitoring helps in early detection and timely intervention.
Choice B rationale:
Notifying the physician when weight gain exceeds more than 20 g/day might be too late for intervention. Daily weight monitoring is essential to detect trends and intervene promptly to manage excess fluid volume.
Choice C rationale:
Placing the infant in a car seat to minimize movement is not directly related to managing excess fluid volume in congestive heart failure. It is essential for safety during transportation but does not address the nursing diagnosis.
Choice D rationale:
Administering digoxin as ordered by the physician is a medical intervention for congestive heart failure. While important, the nursing diagnosis is related to excess fluid volume, and the focus should be on nursing interventions such as monitoring daily weights.
Correct Answer is C
Explanation
Choice A rationale
While pain management is important following a cleft palate repair, it does not typically require immediate attention. Pain can be managed with appropriate analgesics and does not typically present an immediate risk to the patient’s health.
Choice B rationale
A patient refusing to ambulate following an appendectomy does not typically require immediate attention. Encouraging mobility is important for recovery, but refusal to ambulate does not present an immediate risk to the patient’s health.
Choice C rationale
Frequent swallowing following a tonsillectomy could indicate post-operative bleeding, which requires immediate attention. Post-tonsillectomy hemorrhage can be a life-threatening condition that requires immediate intervention.
Choice D rationale
While pain at the site of an IV infusion should be addressed, it does not typically require immediate attention unless there are signs of infection or infiltration. It does not present an immediate risk to the patient’s health.
