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 D
Explanation
Choice A rationale
While placing a pillow under the child’s head might seem like a good idea, it’s actually not recommended during a seizure. The child’s movements could be unpredictable, and a pillow could potentially cause suffocation.
Choice B rationale
Removing the child’s eyeglasses is a good idea, but it’s not the first thing you should do. The child’s safety is the top priority, and eyeglasses can be removed once the child is safe.
Choice C rationale
Timing the seizure is important for medical professionals to know, but it’s not the first action to take. The child’s immediate safety is the priority.
Choice D rationale
Moving the child into a side-lying position is the priority. This position helps keep the airway clear and allows any vomit to exit the mouth, reducing the risk of choking.
Correct Answer is B
Explanation
The correct answer is choice B: Instruct the parent to avoid pressing on the abdominal area.
Rationale for each choice:
- Choice A: Schedule the child for an abdominal ultrasound. While an ultrasound may be necessary for further diagnosis, it is not the immediate priority. The child’s symptoms suggest a possible Wilms’ tumor, a type of kidney cancer that primarily affects children. An ultrasound can help confirm this diagnosis, but it should not be the first action.
- Choice B: Instruct the parent to avoid pressing on the abdominal area. This is the correct answer. If the child has a Wilms’ tumor, pressing on the abdominal area could potentially cause the cancer to spread. Therefore, it is crucial to avoid any unnecessary pressure on the abdomen until further medical evaluation can be performed.
- Choice C: Determine if the child is having pain. While assessing for pain is an important part of nursing care, it is not the immediate priority in this situation. The child’s symptoms need urgent medical attention, and assessing for pain will not provide the necessary information to guide immediate care.
- Choice D: Obtain a urine specimen for a urinalysis. Although a urinalysis can provide valuable information about a patient’s health, it is not the immediate priority in this situation. The child’s symptoms suggest a possible Wilms’ tumor, which requires immediate medical attention. A urinalysis may be part of the diagnostic process, but it should not be the first action taken.
