A client has received a prescription for a fluid bolus of 0.9% sodium chloride, 200 mL to be infused in 30 minutes. How many mL/hr should the nurse program the infusion pump to deliver? (Please enter the numerical value only.)
The question is asking for the rate at which the infusion pump should be programmed to deliver a fluid bolus of 200 mL in 30 minutes. This can be calculated using the formula for rate which is volume divided by time.
The Correct Answer is ["400"]
Step 1: Convert the volume of fluid to be infused from mL to L (since the rate is usually measured in mL/hr):
200 mL = 200 mL (No conversion needed as the volume is already in mL)
Step 2: Convert the time for infusion from minutes to hours (since the rate is usually measured in mL/hr):
30 minutes = 30 ÷ 60 = 0.5 hours
Step 3: Calculate the rate (volume ÷ time):
Rate = Volume ÷ Time
Rate = 200 mL ÷ 0.5 hours
Rate = 400 mL/hr
The nurse should program the infusion pump to deliver at a rate of 400 mL/hr.

Correct Answer is B
Explanation
Choice A reason: Eating high-protein foods to achieve ideal body weight is generally a healthy practice, but it is not directly related to the management of the client's current condition involving pain in the toe.
Choice B reason: Patients with gouty arthritis should avoid acetylsalicylic acid (aspirin) as it can lead to an increase in uric acid levels, potentially exacerbating gout attacks. Instead, medications that do not affect uric acid levels should be used for pain relief.
Choice C reason: Wrapping joints with an elastic bandage can provide support and reduce swelling, but it is not the primary intervention for sudden pain in the toe following an appendectomy, especially when the patient has a history of gouty arthritis.
Choice D reason: Supporting joints in an extended position while resting can provide comfort and may prevent stiffness, but it does not address the acute management of gouty arthritis or diabetic complications that could be causing toe pain.
Correct Answer is D
Explanation
Choice A reason: While obtaining a 12-lead electrocardiogram is important for monitoring cardiac function, it is not as frequent or specific as potassium monitoring for hyperkalemia management.
Choice B reason: Evaluating glucose levels is necessary due to the risk of hypoglycemia from insulin administration, but the priority is monitoring potassium levels in hyperkalemia.
Choice C reason: Monitoring intake and output is part of fluid balance management but is secondary to the critical need to monitor serum potassium levels.
Choice D reason: Frequent assessment of serum potassium levels is essential to evaluate the effectiveness of the dextrose and insulin therapy in lowering potassium levels.
