A nurse is assisting with the care of a client who is hypovolemic due to blood loss following a motor-vehicle crash and needs a blood transfusion immediately. The nurse should anticipate a prescription for which of the following IV solutions while awaiting blood from a type and cross-match?
Dextrose 10% in water
Lactated Ringer's
0.33% sodium chloride
0.45% sodium chloride
The Correct Answer is B
A. Dextrose 10% in water: Dextrose solutions provide calories but do not restore volume or replace electrolytes. They are not typically used in hypovolemic shock.
B. Lactated Ringer's: Lactated Ringer’s solution is an isotonic solution containing sodium, potassium, calcium, and lactate, which helps restore both fluid volume and electrolytes in the case of hypovolemic shock. It is commonly used while awaiting blood transfusions.
C. 0.33% sodium chloride: This is a hypotonic solution that can cause fluid to shift into cells and is not appropriate for fluid resuscitation in hypovolemia, which requires an isotonic solution.
D. 0.45% sodium chloride: This is a hypotonic solution as well, and it could worsen hypotension by causing fluid shifts into the cells, which is not ideal for treating hypovolemic shock.

Correct Answer is ["100"]
Explanation
To calculate the IV flow rate, the following formula is used:
Flowrate(gtt/min) = Volume /Time× Dropfactor(gtt/mL)
Given:
- Volume = 100 mL
- Time = 60 minutes
- Drop factor = 60 gtt/mL
Flowrate(gtt/min)= 10060× 60
=1.67×60
=100gtt/min (rounded to the nearest whole number)
Correct Answer is C
Explanation
. "Bradycardia is an early indicator of a pneumothorax.": Tachycardia, not bradycardia, is an early sign of pneumothorax.
B. "Administer a bronchodilator to the child after chest percussion therapy.": Bronchodilators are typically administered before chest physiotherapy to open airways and enhance mucus clearance.
C. "Engage the child in daily aerobic exercise.": Exercise promotes lung function, airway clearance, and overall physical health in children with cystic fibrosis.
D. "A pigeon-shaped chest might become evident as the disease progresses.": This is incorrect; barrel chest deformities, not pigeon chest, are associated with cystic fibrosis.
