A nurse is providing teaching to the parent of a 6-month-old infant who is teething and having difficulty sleeping. Which of the following instructions should the nurse include?

A. A flat anterior fontanel can indicate dehydration in infants, so this finding does not indicate effective treatment.

B. Oliguria, or decreased urine output, is a sign of dehydration and would not indicate effective treatment.

C. Oral intake of 4 oz every 3 hours indicates that the infant is able to drink fluids and is likely rehydrated, indicating effective treatment.

D. A capillary refill of 4 seconds is prolonged and can indicate poor perfusion, which is not indicative of effective treatment for dehydration.

A. Detaching the needle from the syringe before discarding it increases the risk of needle-stick injuries. Needles should be disposed of as one unit to minimize the risk of injury.

B. Broken glass should be disposed of in a puncture-proof container to prevent injuries. Placing it directly in a wastebasket increases the risk of puncture injuries to individuals handling the waste.

C. Recapping needles increases the risk of needle-stick injuries. Needles should not be recapped after use unless there is no safer alternative. Instead, they should be disposed of as one unit.

D. Lancets, needles, and other sharp objects should be placed in puncture-proof containers immediately after use to prevent injuries. This practice helps ensure the safety of healthcare workers and others who handle waste.
