The healthcare provider has prescribed heparin, 3 units/kg to be administered via IV push for a client who weighs 175 pounds. The vial is labeled as "100 units/mL." How many mL should the nurse administer? (Please enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2.4"]
Step 1: Convert the weight from pounds to kilograms. We know that 1 kg = 2.2 lbs. So, the weight in kg is:
175 lbs ÷ 2.2 = 79.55 kg
Step 2: Calculate the total units of heparin needed. The prescription is for 3 units/kg, so:
3 units/kg × 79.55 kg = 238.65 units
Step 3: Calculate the volume of heparin to administer. The vial is labeled as "100 units/mL", so:
238.65 units ÷ 100 units/mL = 2.39 mL
So, the nurse should administer approximately 2.4 mL of heparin (rounded to the nearest tenth).

Correct Answer is C
Explanation
Choice A reason: Decreased bowel sounds may indicate gastrointestinal issues but are not directly related to weight gain associated with fluid accumulation in cirrhosis.
Choice B reason: An increased respiratory rate can be a sign of many conditions, including respiratory distress, but it does not correlate specifically with weight gain due to fluid retention in cirrhosis.
Choice C reason: Increased abdominal girth is a common finding in cirrhosis due to ascites, which is the accumulation of fluid in the peritoneal cavity and can lead to significant weight gain.
Choice D reason: Decreased level of consciousness may be a sign of hepatic encephalopathy in cirrhosis but is not a direct correlation to the weight gain reported by the client.
Correct Answer is C
Explanation
Choice A reason: Cooling the bottle is not necessary and shaking it is only required if the instructions specify to do so to mix the medication.
Choice B reason: Inserting the tip of the dropper into the ear canal is not recommended as it can introduce bacteria and cause injury.
Choice C reason: Pulling the pinna up and back in adults helps to straighten the ear canal, allowing for proper delivery of the medication.
Choice D reason: Administering the drops with the head held upright is not the correct method; the head should be tilted to allow the drops to flow down into the ear canal.
