A nurse is preparing, to administer ampicillin 150 mg IM to an infant. Available is ampicillin injection 250 mg/mL. How many mL should the nurse administer? Round the answer off to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.6"]
Given:
Desired dose of ampicillin: 150 mg
Concentration of ampicillin injection: 250 mg/mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
150 mg / Volume = 250 mg/mL
Step 3: Solve for the unknown volume:
Volume = 150 mg / 250 mg/mL
Step 4: Calculate the volume:
Volume = 0.6 mL

Correct Answer is ["125"]
Explanation
Given:
Total volume to be infused: 1,000 mL
Infusion time: 8 hours
Step 1: Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
Step 2: Substitute the values:
Infusion rate (mL/hr) = 1,000 mL / 8 hr
Step 3: Calculate the infusion rate:
Infusion rate (mL/hr) = 125 mL/hr
Correct Answer is D
Explanation
A) Ketorolac 10mg PO every 6hr PRN pain: Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used for pain management after cesarean birth. However, it should not be used for more than 5 days due to potential renal side effects, gastrointestinal bleeding, and ulceration risks. A prescription for this drug 10mg every 6 hours could be appropriate if within the 5-day limit.
B) Ciprofloxacin 1000mg daily: Ciprofloxacin is an antibiotic often prescribed for certain infections. In a postoperative client, it might be prescribed for a urinary tract infection or another bacterial infection. The dose of 1000mg daily is within normal therapeutic ranges for many conditions, and there is no immediate reason to clarify it in the context of routine postoperative care.
C) 0.45% sodium chloride 1000mL-125mL/hr by continuous IV infusion: This IV fluid prescription specifies a normal saline solution at a moderate infusion rate of 125mL/hr, which is generally appropriate for postoperative fluid management. The administration of fluids is essential to prevent dehydration, maintain hydration, and promote healing in the postoperative period.
D) Magnesium hydroxide 60mL PO at bedtime: Magnesium hydroxide is commonly used as a laxative or antacid, but giving 60mL at bedtime raises a concern. Magnesium hydroxide has a significant laxative effect and can lead to dehydration, electrolyte imbalances, and excessive bowel movement. It is contraindicated in clients with impaired renal function, which is often a concern postoperatively, particularly in clients who may not be eating or drinking adequately. Additionally, in the immediate postoperative period following a cesarean, using a laxative in such a high dose could exacerbate the risk of discomfort, bloating, or diarrhea, and may not be necessary unless there is a specific indication for it.
