How can the hormone insulin affect a patient's metabolism?
Insulin helps to lower blood glucose levels by promoting the uptake of glucose into cells.
Insulin increases blood glucose levels by breaking down glycogen in the liver.
Insulin promotes the breakdown of fats and proteins to increase energy production.
Insulin decreases the metabolic rate by inhibiting thyroid hormone production.
The Correct Answer is A
A. Insulin helps to lower blood glucose levels by promoting the uptake of glucose into cells:
Insulin facilitates the entry of glucose into cells for energy use or storage, thereby lowering blood glucose levels.
B. Insulin increases blood glucose levels by breaking down glycogen in the liver:
This describes the action of glucagon, not insulin.
C. Insulin promotes the breakdown of fats and proteins to increase energy production:
Insulin actually inhibits fat and protein breakdown and promotes storage of nutrients.
D. Insulin decreases the metabolic rate by inhibiting thyroid hormone production:
Insulin has no direct effect on thyroid hormone production or metabolic rate regulation.

Correct Answer is A
Explanation
A. Verify provider order to discontinue the tube:
The first action in the nursing process is to verify the provider’s order before removing any medical device. It ensures the action is legally and clinically appropriate.
B. Observe the amount and color of drainage:
Important to evaluate after the order is confirmed, but not the first step.
C. Perform hand hygiene and don gloves:
Necessary for infection control, but only after verifying the order.
D. Disconnect the tube from the wall suction:
This is part of the procedure itself, not the initial preparatory step.
Correct Answer is D
Explanation
A. Remove and reinsert the NG tube:
This is invasive and should only be done with a prescription after troubleshooting less invasive options.
B. Request a prescription for a medication to ease the client's anxiety:
While anxiety relief is important, it is not the priority. The discomfort likely stems from ineffective suctioning.
C. Irrigate the NG tube with 100 mL of sterile water:
The typical irrigation amount is 30 mL or less. 100 mL is excessive and may worsen distention.
D. Check to see if the suction equipment is working:
If the suction is not working, the NG tube may not be decompressing the stomach, leading to bloating and discomfort, which must be addressed first.
