An adrenergic agonist is ordered for a patient in shock. The nurse will note that this drug has had its primary intended effect if which expected outcome occurs?

Decreased urine output

Increased cardiac output

Volume restoration

Reduced anxiety

Answer and Explanation

The Correct Answer is B

A. Decreased urine output is not the primary intended effect of an adrenergic agonist in the

treatment of shock. While adrenergic agonists may increase blood pressure, leading to a decrease in urine output due to vasoconstriction, the primary goal of administering these drugs in shock is to improve tissue perfusion and cardiac output.
B. Increased cardiac output is the primary intended effect of adrenergic agonists in the treatment of shock. These medications stimulate adrenergic receptors, leading to increased heart rate, contractility, and stroke volume, ultimately improving cardiac output and tissue perfusion.
C. Volume restoration may be a secondary effect of administering fluids along with adrenergic agonists in the treatment of shock, but it is not the primary intended effect of the medication
itself.

D. Reduced anxiety is not a primary goal of administering adrenergic agonists in the treatment of shock. While these medications may have anxiolytic effects in certain situations, the primary goal is to improve cardiovascular function and tissue perfusion.

Correct Answer is ["0.6"]

Explanation

To find out how many milliliters (mL) of methylnaltrexone should be administered to achieve a dose of 12 mg, we need to set up a proportion based on the available concentration.

Given:

Methylnaltrexone concentration: 8 mg per 0.4 mL
Desired dose: 12 mg

We can set up the proportion as follows:

8 /0.4 = 12 / x

Where ( x ) is the unknown amount of methylnaltrexone in milliliters.

To solve for ( x ), we can cross multiply and then divide:

8x = 0.4 12

8x = 4.8

x = 4.8/8

x = 0.6

Therefore, the nurse should administer 0.6 mL of methylnaltrexone.

Correct Answer is ["50"]

Explanation

Gtt/min= Volume per hour× Drop factor/ Time in minutes per hour Given:

Volume per hour = 150 mL Drop factor = 20 gtt/mL

Time in minutes per hour = 60 minutes Gtt/min= 150mL/hr×20gtt/mL/60min/hr Gtt/min=50
Therefore, the nurse should set the manual IV infusion to deliver 50 gtt/min
