The healthcare provider prescribes 1 liter of lactate Ringer's to infuse in 8 hours. The IV administration set delivers 15 gtt/mL. How many mL/hour should the nurse program the infusion pump? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["125"]
Calculation:
- Convert the total volume from liters (L) to milliliters (mL).
Total volume = 1 L × 1000 mL/L
= 1000 mL.
Infusion time = 8 hours.
- Calculate the infusion rate in milliliters per hour (mL/hour).
Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hour)
= 1000 mL / 8 hours
= 125 mL/hour.
Answer: 125

Correct Answer is A
Explanation
Rationale:
A. Position the infant in a supine position while sleeping: Placing infants on their backs to sleep is the single most effective and evidence-based method for reducing the risk of SIDS. This recommendation is central to all safe sleep guidelines and should be emphasized as the most critical point in parent education.
B. Keep a bulb syringe accessible for use for an infant: While helpful for managing nasal or oral secretions, having a bulb syringe nearby does not directly prevent SIDS. It is supportive care but not a core preventive measure.
C. Remove pillows and soft toys from the crib at bedtime: This is an important secondary recommendation to reduce suffocation risks. However, it complements but does not replace the significance of proper sleep positioning in SIDS prevention.
D. Do not prop bottles for an infant during naps and bedtime: Bottle propping increases the risk of aspiration and ear infections but is not directly related to SIDS. It is an unsafe practice, but not the most important intervention for SIDS prevention.
Correct Answer is ["B","C","D"]
Explanation
Rationale:
A. Insert 30 mL air bolus while auscultating over abdomen: Introducing air into a misplaced NG tube in the chest cavity may worsen injury or cause a pneumothorax or tension pneumothorax, especially if the tube has entered the pleural space or lung.
B. Remove the NG tube: Chest x-ray confirms malposition in the chest cavity, likely the pleural space or lung. The tube must be removed immediately to prevent further trauma or air/fluid accumulation.
C. Clamp the NG tube: Clamping prevents the entry or exit of air and fluids, minimizing risk of complications like aspiration or worsening pneumothorax while awaiting removal or re-evaluation.
D. Auscultate chest and abdomen following removal of NG tube: Assessing for abnormal breath or bowel sounds post-removal helps detect potential complications such as pneumothorax, hemothorax, or abdominal injury.
E. Connect the NG tube to low wall suction: Connecting a malpositioned NG tube to suction could draw air or fluids from the pleural space or lung, worsening the trauma or leading to complications such as lung collapse.
