A client who weighs 132 lb receives a prescription for lorazepam 44 mcg/kg IV to be administer 20 minutes before a scheduled procedure. The medication is available in 2 mg/mL vial. How many mL should the nurse administer?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.3"]
Convert pounds to kilograms.
- 1 pound = 0.453592 kilograms
- 132 pounds * 0.453592 kg/pound = 59.87 kilograms
Step 2: Calculate the total dose in micrograms.
- 44 micrograms/kilogram * 59.87 kilograms = 2635.08 micrograms
Step 3: Convert micrograms to milligrams.
- 1 milligram = 1000 micrograms
- 2635.08 micrograms / 1000 micrograms/milligram = 2.63508 milligrams
Step 4: Calculate the volume to be administered.
- Concentration of lorazepam = 2 milligrams/milliliter
- Volume = Dose / Concentration
- Volume = 2.63508 milligrams / 2 milligrams/milliliter = 1.31754 milliliters
Therefore, the nurse should administer approximately 1.3 milliliters of the lorazepam solution.

Correct Answer is A
Explanation
Rationale
A. Monitoring intake and output closely is essential to assess fluid balance and ensure adequate hydration. Replacing fluids intravenously based on this assessment helps maintain hemodynamic stability and prevent dehydration, electrolyte imbalances, and hypovolemia.
B. After surgery for fistula repair, it is important to monitor wound drainage to assess for complications such as infection or delayed healing. Excessive drainage may indicate issues with wound healing or ongoing inflammation, requiring timely intervention.
C. Turning the client every 2 hours helps prevent complications such as pressure ulcers and respiratory complications. It promotes circulation, prevents skin breakdown, and aids in lung expansion. However, while important, this intervention is more focused on preventing physical complications rather than directly addressing the client's immediate medical needs post-surgery.
D. Clients with inflammatory bowel disease, especially those undergoing surgery and critically ill, are at increased risk for skin breakdown due to factors such as decreased mobility, medication effects, and overall health status. Regular skin assessments help detect early signs of breakdown and allow for prompt intervention to prevent pressure ulcers or skin complications.
Correct Answer is A
Explanation
Rationale
A. In the early phase following a burn injury, there is increased capillary permeability due to the release of inflammatory mediators. This results in fluid shifting from the intravascular space into the interstitial space (capillary leaking), leading to hypovolemia and decreased tissue perfusion. Administering crystalloid fluids helps to restore intravascular volume (fluid resuscitation) and improve tissue perfusion.
B. Burn injuries can lead to increased evaporative water loss through damaged skin (insensible water loss). Crystalloid fluids help to replace this lost fluid and maintain adequate hydration status in the client.
C. In severe burn injuries, there may be a need for blood transfusions due to hemorrhage or ongoing blood loss. Crystalloid fluids can help to extend plasma volume temporarily until blood products are available for transfusion, thereby supporting circulatory stability.
D. Burn injuries can disrupt electrolyte balance due to fluid shifts and tissue damage. Crystalloid fluids contain electrolytes (such as sodium and chloride) that help to restore and maintain electrolyte balance in the body.
