A nurse is preparing to administer lactated Ringer's 1,500 mL IV to infuse at 50 mL/hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale:

Keeping a can of concentrated formula in the refrigerator for 3 days after opening it is not safe. Once a can of formula is opened, it should be used within 24 hours and stored in the refrigerator. After 24 hours, any leftover formula should be discarded to prevent the risk of bacterial contamination.

Choice B rationale:

Diluting ready-to-feed formula with water is incorrect. Ready-to-feed formula is already prepared and does not need to be diluted further. Adding water to ready-to-feed formula can dilute its nutritional content and may not provide the necessary nutrients for the baby.

Choice C rationale:

Boiling tap water for 2 minutes and cooling it before mixing it with powdered formula is the correct method for safe formula preparation. Boiling the water kills harmful bacteria and ensures the formula is safe for the baby to consume. It is essential to cool the boiled water before mixing it with powdered formula to reach an appropriate feeding temperature.

Choice D rationale:

Ensuring that all bottles contain BPA (bisphenol A) is not a relevant consideration for formula preparation. BPA is a chemical that was previously used in some plastics, including baby bottles, but has been banned in baby bottles and sippy cups in several countries due to its potential health risks. Most modern baby bottles are BPA-free, and this statement does not address the safe handling and preparation of formula for the baby.

• A. Incorrect. Withholding pain medications for 24 hr after the old patch is removed is a harmful action that could cause severe withdrawal symptoms and uncontrolled pain for the client. The nurse should respect the client's right to refuse treatment and explore the reasons for their decision.
• B. Correct. Asking another nurse to witness the disposal of the new patch is a safe and legal action that follows the policies and procedures for handling controlled substances. The nurse should document the disposal of the new patch and report it to the appropriate authority.
• C. Incorrect. Sealing the patches in a plastic bag and placing them in the client's trash basket is an unsafe and illegal action that could lead to diversion, misuse, or accidental exposure of fentanyl to others. The nurse should dispose of the patches in a secure and designated container that prevents access by unauthorized persons.
• D. Incorrect. Sticking the two patches to each other and placing them in the sharps bin is an unsafe and improper action that could cause contamination, injury, or infection to others who handle or dispose of sharps waste. The nurse should dispose of the patches separately and carefully, avoiding contact with their adhesive surfaces.
