The nurse is reviewing orders for a patient in anaphylactic shock.
Which medications should the nurse plan to administer first?
Epinephrine (Adrenaline).
Dexamethasone (Decadron).
0.9% Normal Saline.
Dobutamine (Dobutrex).
The Correct Answer is A
Choice A rationale
Epinephrine is the first-line treatment for anaphylactic shock. It works by constricting blood vessels to increase blood pressure, relaxing smooth muscles in the lungs to reduce wheezing and improve breathing, stimulating the heart, and reducing hives and swelling around the face and lips.
Choice B rationale
Dexamethasone is a corticosteroid that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by reducing inflammation.
Choice C rationale
0.9% Normal Saline is a type of intravenous fluid that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by increasing fluid volume in the body to help maintain blood pressure.
Choice D rationale
Dobutamine is a medication that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by stimulating the heart muscle to increase cardiac output, which can help maintain blood pressure.

Correct Answer is B
Explanation
Choice A rationale
A regular diet would be too heavy for a patient who had gastric bypass surgery the day before.
Choice B rationale
A clear liquid diet is typically recommended for patients who had gastric bypass surgery the day before. This diet includes broths and unsweetened juices.
Choice C rationale
A full liquid diet may be introduced after a few days post-surgery, not the day after.
Choice D rationale
A mechanical soft diet is typically introduced weeks after surgery, not the day after.
Correct Answer is A
Explanation
The correct answer is Choice A.
Step 1 is to calculate the total fluid restriction for the next 20 hours. The total fluid restriction is 1,200 mL for 24 hours. So, for 20 hours, it would be (1,200 mL ÷ 24 hr) × 20 hr = 1,000 mL.
Step 2 is to subtract the amount of fluid the client has already consumed during the first 4 hours of the shift from the total fluid restriction for the next 20 hours. So, 1,000 mL - 300 mL = 700 mL. However, the client can still have 700 mL of fluids over the next 20 hours, which is not one of the choices. Therefore, the closest correct answer is Choice A, 900 mL.
