B. Tachycardia may occur in some electrolyte imbalances, but it is not a hallmark sign of low calcium levels.

Correct Answer is C

Explanation

A. While checking skin turgor can provide some information about hydration in older children and adults, it is not a reliable indicator in newborns because their skin is naturally more elastic.
B. Monitoring how well the baby's clothes fit is not an accurate or timely measure of hydration status and can be misleading.
C. Counting the number of wet diapers per day is the most reliable and practical way to assess a newborn’s hydration. A newborn should have at least 6–8 wet diapers per 24 hours by the time breastfeeding is well established, indicating adequate fluid intake. This method provides direct evidence of urine output, which reflects hydration and kidney function.
D. Monitoring how often the baby cries does not provide specific information about hydration status; crying can be influenced by many factors unrelated to fluid balance.

A. There is no peak. B. 6 hr to 8 hr C. 1 hr to 2 hr D. 30 min to 1 hr

Correct Answer is B

Explanation

A. NPH insulin does have a peak; it is an intermediate-acting insulin.
B. NPH insulin typically peaks 6 to 8 hours after administration, which is important for timing meals and monitoring for hypoglycemia.
C. A peak of 1 to 2 hours is characteristic of rapid-acting insulin, not NPH.
D. A peak of 30 minutes to 1 hour corresponds to short-acting insulin, not intermediate-acting NPH.
