Correct Answer is ["2.4"]

Explanation

Rationale:
To calculate the dosage of Nitroprusside in mcg/min, first convert the client's weight from pounds to kilograms, knowing that 1 kg equals 2.2 lbs. Therefore, 176 lbs is approximately 80 kg. Next, multiply the client's weight in kg by the dosage rate: 0.5 mcg/kg/min. So, 80 kg * 0.5 mcg/kg/min equals 40 mcg/min. To find mcg/hr, multiply the mcg/min dosage by 60, the number of minutes in an hour, which gives us 2400 mcg/hr. Finally, to calculate mL/hr, use the concentration of the drug: 500 mg in 500 mL. Since 1 mg equals 1000 mcg, 500 mg is 500,000 mcg. Divide the hourly dosage in mcg by the total number of mcg in the available fluid to find the mL/hr. Thus, 2400 mcg/hr divided by (500,000 mcg / 500 mL) results in 2.4 mL/hr. Rounded to the nearest tenth, the final dosages are 40 mcg/min, 2400 mcg/hr, and 2.4 mL/hr.

A. Maintain the prescribed daily fluid restriction. B. Position the client's head of bed with no more than 10 degrees of elevation. C. Turn and reposition the client every 2 hours while on bedrest. D. Provide frequent oral hygiene every 2 hours for the client.

Correct Answer is A

Explanation

A. Maintaining the prescribed daily fluid restriction is crucial to manage hyponatremia and prevent further complications.
B. Head elevation is important but not the primary priority in SIADH management.
C. Turning and repositioning is necessary for bedrest patients but not specific to SIADH.
D. Providing oral hygiene is important for overall care but not the primary intervention for SIADH.
