A client is to receive 500 mg of metformin. The available strength is 250 mg per tablet. How many tablets should the nurse give per dose?

A. Fontanel: The anterior fontanel is a soft spot on an infant’s skull where cranial bones have not yet fused. It becomes sunken with dehydration due to reduced intracranial and interstitial fluid and appears normal when the infant is adequately hydrated.

B. Thorax: The thorax does not show visible signs of sunken appearance with dehydration. Chest wall changes are unrelated to fluid status in infants.

C. Pupil: Pupils respond to light and neurological function, not hydration status. They do not become sunken during dehydration.

D. Nares: The nares (nostrils) may flare in respiratory distress but are not affected by hydration status and do not provide an indicator of fluid balance.

A. Ask a colleague to take over preparation when interrupted: Delegating can help maintain safety if the colleague is qualified, but frequent handoffs increase the risk of miscommunication and errors. The priority is to maintain focus during preparation rather than relying on multiple caregivers.

B. Prepare all medications at once to improve efficiency: Preparing multiple medications simultaneously increases the chance of confusion, incorrect labeling, or cross-contamination. Efficiency should never compromise accuracy or patient safety.

C. Continue preparation despite interruptions to maintain schedule: Working while distracted significantly increases the risk of medication errors, including wrong drug, dose, or route. Minimizing distractions is critical to ensure safe administration.

D. Complete preparation for one client at a time without distractions: Focusing on one client’s medications at a time allows the nurse to verify the five rights accurately and reduces errors caused by interruptions or multitasking. This approach aligns with best practices for medication safety.
