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.)

Borderline.

• A. Borderline personality disorder is characterized by a pervasive pattern of instability in interpersonal relationships, self-image, and affect, as well as marked impulsivity and recurrent suicidal behavior. The client's history of seeking counseling for relationship problems and selfinflicted lacerations are consistent with this disorder. Therefore, this choice is correct.
• B. Antisocial personality disorder is characterized by a disregard for and violation of the rights of others, as well as a lack of remorse for one's actions. The client's behavior does not indicate this disorder. Therefore, this choice is incorrect.
• C. Paranoid personality disorder is characterized by a pervasive distrust and suspiciousness of others, as well as a tendency to interpret others' motives as malevolent. The client's behavior does not indicate this disorder. Therefore, this choice is incorrect.
• D. Histrionic personality disorder is characterized by excessive emotionality and attentionseeking behavior, as well as a tendency to dramatize situations and exaggerate emotions. The client's behavior does not indicate this disorder. Therefore, this choice is incorrect.

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.
