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. Assess the bowel sounds:
Bowel sounds are not directly related to the assessment of ascites. Bowel sounds are more relevant in assessing gastrointestinal function and peristalsis. While bowel changes could potentially be a sign of complications, monitoring abdominal girth is more specific to tracking ascites.
B. Frequently ambulate child:
While ambulation is important for overall health, it's not a direct assessment method for monitoring ascites. Ambulating a child might have benefits, but it won't provide specific information about the presence or progression of ascites.
C. Weigh child weekly:
Weekly weighing can provide some information about overall fluid balance, but it might not be as sensitive as measuring abdominal girth when it comes to detecting changes in ascites. Additionally, monitoring weight alone might not give insight into the distribution of fluid in the abdominal cavity.
D. Monitor and measure the abdominal girth.
Explanation: The presence of ascites (accumulation of fluid in the abdominal cavity) in a child with nephrotic syndrome could indicate worsening kidney function and fluid balance. Monitoring and measuring the abdominal girth is a reliable way to assess changes in the amount of fluid accumulation over time. An increase in abdominal girth could suggest a worsening condition.
Correct Answer is D
Explanation
A. Elevated blood glucose is remarkable with Cushing's Triad:
Elevated blood glucose is not one of the components of Cushing's Triad. The triad focuses on cardiovascular and respiratory changes associated with increased intracranial pressure, not blood glucose levels.
B. Cushing's Triad includes a positive Macawen's sign:
Macawen's sign is not part of Cushing's Triad. Cushing's Triad is specifically related to the physiological responses seen in response to increased intracranial pressure and is not associated with Macawen's sign.
C. Cushing's Triad includes tachycardia, seizures and rapid respirations:
This option is not accurate. Cushing's Triad involves bradycardia (slow heart rate), irregular respirations, and a widening pulse pressure. Tachycardia (rapid heart rate) and seizures are not part of Cushing's Triad but might be indicative of other medical conditions or complications.
D. Bradycardia, irregular respirations and a widening pulse pressure.
Explanation: Cushing's Triad is a set of three clinical signs that are indicative of increased intracranial pressure (ICP) and are considered ominous as they suggest serious brain injury or pathology. The triad consists of:
Bradycardia: This refers to a slow heart rate. As intracranial pressure increases, it can lead to a decreased heart rate due to pressure on the brainstem, which is involved in regulating heart rate.
Irregular Respirations: Increased ICP can affect the brainstem's control over breathing, leading to irregular patterns of breathing, often known as Cheyne-Stokes respiration. This is characterized by periods of rapid breathing followed by apnea (temporary cessation of breathing).
Widening Pulse Pressure: Pulse pressure is the difference between systolic and diastolic blood pressure. An increase in ICP can cause an increase in systolic blood pressure and a decrease in diastolic blood pressure, leading to a widening pulse pressure.
