A nurse is preparing to administer lactated Ringer's 400 mL IV bolus to infuse over 3 hr. The drop factor of the manual IV tubing is 20 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.)

Full Explanation
Calculate the flow rate in mL/hour: 400 mL / 3 hours = 133.33 mL/hour (approximately)
Convert the flow rate to mL/minute: 133.33 mL/hour / 60 minutes/hour = 2.22 mL/minute (approximately)
Calculate the drops per minute: 2.22 mL/minute 20 gtt/mL = 44.4 gtt/minute
Round to the nearest whole number: 44 gtt/minute

The nurse is caring for a pediatric client who experienced a "greenstick" fracture. The client's mother asks the nurse what it means to have this type of fracture. Which of the following statements should the nurse make?
A. This means that the bone broke all the way through, perpendicular to the shaft.
This describes a transverse fracture, where the bone breaks completely across and perpendicular to the shaft. It does not describe a greenstick fracture.
B. This means that the bone broke in a spiral pattern.
A spiral fracture is caused by a twisting force, which results in a helical break. This is not a greenstick fracture.
C. This means that the bone bent and only the outer arc of the bend broke.
A greenstick fracture occurs when the bone bends and cracks on the outer arc but does not break completely through. This type of fracture is more common in children because their bones are softer and more flexible.
D. This means that the broken bone ends splintered into smaller pieces.
This describes a comminuted fracture, where the bone breaks into several pieces. It does not match the description of a greenstick fracture.

The nurse is planning care for a client with type 1 diabetes mellitus. When planning administration for rapid-acting insulin Lispro, the nurse knows to administer it during which timeframe based on the onset of action?
A. Lispro lasts 24 hours and does not have to be timed with meals.
This statement is incorrect. Lispro is a rapid-acting insulin, and its duration of action is much shorter than 24 hours. It is typically effective for about 3-5 hours.
B. 60 minutes before meals.
Administering Lispro 60 minutes before meals would be too early, as it peaks in about 1-2 hours after injection and works best when given closer to meal times.
C. 15-30 minutes before meals.
Lispro should be administered 15-30 minutes before meals to match the onset of action, which begins within 15 minutes of injection. This timing allows the insulin to be active when blood glucose rises after eating.
D. 2-6 hours before meals.
Lispro does not require administration 2-6 hours before meals, as this would not align with its rapid onset of action.

Which assessment finding is most indicative of hypernatremia?
A. Ascending muscle weakness
Ascending muscle weakness is more characteristic of hypokalemia (low potassium levels) rather than hypernatremia.
B. Muscle tetany and hyperreflexia
Muscle tetany and hyperreflexia are typically seen in hypocalcemia (low calcium levels) or hypomagnesemia (low magnesium levels), not hypernatremia.
C. Poor turgor and dry mucous membranes
Hypernatremia (high sodium levels) commonly causes dehydration, which results in poor skin turgor and dry mucous membranes. This is a key clinical sign of hypernatremia.
D. Bradycardia and hypotension
Bradycardia and hypotension are more commonly associated with hypovolemia (low blood volume) or hypotension, but they are not specific to hypernatremia.
