A nurse is reinforcing teaching about home safety needs for a toddler. Which of the following statements by the toddler's parents indicates an understanding of the teaching?

Rationale:

A. "We will keep the number for poison control stored in our phones.": Having the poison control number readily accessible is a key component of home safety for toddlers, who are at high risk for accidental ingestion. Prompt access supports rapid emergency response and guidance.

B. "We will make sure our hot water heater is set to 54° C (129° F)": This temperature setting is too high and increases the risk of scald burns. Water heaters should be set at or below 49° C (120° F) to reduce the chance of accidental burns during bathing or handwashing.

C. "We will make sure to turn pot handles towards the front of the stove.": Turning pot handles to the front makes them easier for a toddler to grab, increasing burn and injury risk. Handles should always be turned toward the back or center of the stove to keep them out of reach.

D. "We will store medications on a high surface that our child can't reach": High surfaces are not secure enough, as toddlers may climb. Medications should be stored in locked cabinets to ensure they are completely inaccessible to curious children.

Rationale:

A. Heparin 5000 U subcutaneous every 8 hr: Using "U" for units can be misread as zero, potentially causing a tenfold overdose. The correct transcription uses the full word "units" to prevent errors.

B. M50, 10g PO delly: This prescription contains multiple errors: "M50" is unclear, "10g" may be excessive or incorrect dosing, and "delly" is an incorrect abbreviation for daily. This transcription is inaccurate and unsafe.

C. Lorazepam 0.5 mg PO PRN at bedtime: Although mostly correct, "PRN at bedtime" can be confusing. It is clearer to specify "PRN for anxiety at bedtime" or "PRN as needed at bedtime" to clarify the indication and timing.

D. Doxazosin 5 mg PO at bedtime: This transcription is clear, uses accepted abbreviations, specifies route and time, and includes no dangerous abbreviations, making it an accurate and safe prescription transcription.
