C.

D.

The two main purposes of diuretics are to increase circulating fluid and lower blood pressure

Answer and Explanation

The Correct Answer is A

A) The two main purposes for diuretics are to decrease fluid and decrease hypertension (lower blood pressure):
Diuretics primarily work by promoting the excretion of excess sodium and water from the body, which decreases fluid volume. This reduction in fluid volume helps to lower blood pressure, especially in conditions like hypertension and heart failure, where fluid buildup can exacerbate symptoms.

B) The two main purposes are to decrease fluid volume in the tissues and circulation, increasing blood pressure:
The primary purpose of diuretics is to decrease fluid volume, which helps lower blood pressure, not increase it. Diuretics are used to reduce the workload on the heart and the risk of complications like stroke and heart failure by lowering blood pressure and removing excess fluid from the body.

C) The two main purposes of diuretics are to increase fluid in the body and blood pressure:
Diuretics do not increase fluid in the body. In fact, they decrease fluid in the body to help reduce blood pressure. This option contradicts the fundamental mechanism of action of diuretics.

D) The two main purposes of diuretics are to increase circulating fluid and lower blood pressure:
Diuretics do not increase circulating fluid; they decrease it. By promoting the excretion of sodium and water, diuretics decrease the volume of circulating fluid, which is a key factor in lowering blood pressure.

Correct Answer is A

Explanation

Convert the dosage to mcg per hour:

15mcg/min×60min/hr=900mcg/hr15

Convert the available nitroglycerin concentration to mcg/mL:

25mg=25,000mcg

Theconcentrationis(25,000mcg/250mL)=100mcg

Calculate the flow rate in mL per hour using the dosage and concentration:

Flowrate(mL/hr)=(900mcg/hr100mcg/mL)=9mL/hr

Correct Answer is D

Explanation

Given:

Ordered dose of clindamycin palmitate: 225 mg

Concentration of clindamycin palmitate oral suspension: 75 mg/5 mL

Step 1: Set up the proportion:

Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)

Step 2: Substitute the values:

225 mg / Volume = 75 mg/5 mL

Step 3: Solve for the unknown volume:

Volume = 225 mg / (75 mg/5 mL)

Volume = 225 mg x (5 mL / 75 mg)

Volume = 15 mL
