A nurse is providing preoperative teaching to an older adult female client who is scheduled for a laminectomy and uses supplements. Which of the following supplements should the nurse identify as increasing the client's risk for hypotension during surgery?

A. Boil bottle rings and nipples for 10 min to ensure sanitization. Boiling for 10 minutes is excessive and can damage bottle parts. A boil time of 5 minutes is typically sufficient for sanitizing feeding equipment before first use.
B. Keep the newborn on a strict 3 hr feeding schedule. Newborns should be fed on demand, which may be more or less frequently than every 3 hours. Hunger cues should guide feeding to promote healthy growth and bonding.
C. Use bottles of refrigerated formula within 48 hr. Prepared formula should be refrigerated and used within 48 hours to ensure safety and prevent bacterial growth. This is a safe practice when storing formula that has not been fed to the infant.
D. Place the newborn on their abdomen for 30 min following each feeding. Placing a newborn on the abdomen increases the risk of sudden infant death syndrome (SIDS). Infants should always be placed on their backs to sleep.

A. Heart rate. The client has a heart rate of 120/min, which is tachycardia and may indicate dehydration, mania-related hyperactivity, or a response to poor nutritional status. This requires immediate follow-up to assess for cardiovascular strain or fluid imbalance.
B. Sleep pattern. While lack of sleep is concerning and a clear symptom of mania, it is a behavioral health issue that typically does not require immediate physiological intervention unless it leads to severe exhaustion or psychosis. It should be addressed, but is not the top priority.
C. Hallucinations. The client is responding to internal stimuli, indicating active psychosis, which poses a safety risk to the client and others. Hallucinations require immediate intervention to stabilize mental health and prevent harm.
D. Skin turgor. Poor skin turgor suggests dehydration, which is a priority physiological concern, especially when paired with tachycardia and failure to recall last food intake. This finding indicates the need for fluid and electrolyte evaluation and possible replacement.
E. Hygiene. The client's unclean appearance reflects self-neglect, a common feature of psychiatric decompensation, and may indicate inability to meet basic needs. This requires prompt attention to prevent complications like infection and assess for functional impairment, though it is secondary to life-threatening physiological or safety concerns.
