Question 1 of 5.
The physician has ordered that ampicillin 250 mg IV be given over 30 minutes. The medication is diluted as recommended in 10 mL in the volume control chamber of a set that has a tubing of 12 mL. Which nursing measure is most accurate considering these facts?
A. Infuse volume at 44 mL/hr.
B. Infuse volume at 22 mL/hr.
C. Infuse volume at 10 mL/hr.
D. Infuse volume at 30 mL/hr.
Explanation: The volume to be infused should be diluted medication volume added to the volume control chamber (10 mL) plus the tubing volume (12 mL). The general formula for calculating IV medications for children is: Rate = Volume to Be Infused X Administration Set Drop Factor (microdrop: 60 gtts/min) / Desired Time to Infuse in Minutes Rate = (10 + 12) 22 × 60 / 30 = 44 mL/hr. (B, C, D) These values are incorrect.
Question 2 of 5.
A client hospitalized with cirrhosis has developed abdominal ascites. The nurse should provide the client with snacks that provide additional:
A. Sodium
B. Potassium
C. Protein

A. Loss of the myelin sheath in portions of the brain and spinal cord
B. An interruption in the transmission of impulses from nerve endings to muscles
C. Progressive weakness and loss of sensation that begins in the lower extremities
D. Loss of coordination and stiff 'cogwheel' rigidity
Explanation: Myasthenia gravis is caused by autoantibodies blocking acetylcholine receptors, interrupting nerve impulse transmission to muscles, leading to weakness.
