The follow questions refer to the patient described below:
A 9 yr. old child with both hydrocephalus and a cardiac defect weighs 55 pounds. He requires digoxin by mouth once daily, the dose should be held if there are any symptoms of toxicity.
Pediatric maintenance dose is 5 mcg/kg daily given as a single dose. After listening to the apical rate for one full minute, you note it is only 50. Should you administer the digoxin as ordered?
NO
Just administer it without checking
instruct mom to give it
Yes
The Correct Answer is A
Digoxin is a medication commonly used to treat certain heart conditions, including some congenital heart defects. It's important to monitor the heart rate and other signs of toxicity when administering digoxin, especially in pediatric patients. Let's break down the information given:
The pediatric maintenance dose of digoxin is 5 mcg/kg daily.
The child weighs 55 pounds (approximately 25 kg).
Given these values, the total daily dose for this child would be:
Total daily dose = 5 mcg/kg × 25 kg = 125 mcg
This total daily dose is usually given as a single dose. However, the child's heart rate is noted to be only 50 beats per minute (bpm). A heart rate of 50 bpm in a child could potentially indicate bradycardia (slow heart rate), which can be a sign of digoxin toxicity. Bradycardia is a known adverse effect of digoxin, and it's important to assess for other signs of toxicity as well, such as nausea, vomiting, and changes in color vision.
In this case, it would be prudent to withhold the digoxin and assess the child further for signs of toxicity or bradycardia. The dose should not be administered until the healthcare provider is consulted and appropriate action is determined.
So, the correct answer is indeed NO. Administering the digoxin without considering the slow heart rate and the potential for toxicity could be unsafe for the child.

Correct Answer is D
Explanation
A) Places the infant in a side-lying position:
Positioning is important in the care of an infant with myelomeningocele. The infant is usually placed in a prone (on the abdomen) position to prevent pressure on the sac and protect the neural tissue. Placing the infant in a side-lying position may not provide the needed protection.
B) Maintains a dry dressing over the sac:
The sac should be kept moist with a sterile, non-adherent dressing moistened with saline to prevent drying and cracking, which could lead to infection.
C) Performs range of motion on the infant's hips:
Infants with myelomeningocele often have flaccid paralysis below the lesion, and excessive manipulation of the lower limbs could cause injury.
D) Takes an axillary temperature:
Rectal temperatures should never be taken, as they can cause mucosal damage or irritate the exposed spinal cord, leading to complications like meningitis. The axillary route is the safest method for temperature assessment.
Correct Answer is A
Explanation
A. Spina bifida.
Explanation: Correct Choice. Spina bifida is a neural tube defect (NTD) that occurs during early fetal development when the neural tube doesn't close completely. It can result in various degrees of spinal cord and nerve damage. This is a suitable example to include when teaching about neural tube defects.
B. Hydrocephalus.
Explanation: Hydrocephalus is not a neural tube defect itself. It's a condition characterized by the accumulation of cerebrospinal fluid in the brain, leading to increased intracranial pressure. It can be caused by various factors, but it's not directly related to neural tube development.
C. Cerebral palsy.
Explanation: Cerebral palsy is a group of motor disorders caused by damage to the developing brain, usually before birth. It is not a neural tube defect. Instead, it's related to brain injury or abnormal development.
D. Muscular dystrophy.
Explanation: Muscular dystrophy is a group of genetic disorders characterized by progressive muscle weakness and degeneration. It's not related to neural tube defects. Muscular dystrophy affects muscle tissue, while neural tube defects involve improper development of the neural tube.
