A.

The two main purposes for diuretics are to decrease fluid and decrease hypertension (lower blood pressure).

B.

The two main purposes are to decrease fluid volume in thetissues and circulation, increasing blood pressure.

C.

The two main purposes of diuretics are to increase fluid in the body and blood pressure.

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

Given:

Volume of fluid: 1 liter = 1000 mL

Infusion time: 6 hours

Drop factor: 10 gtt/mL

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr

Step 1: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Volume (mL) / Time (hr)

Infusion rate (mL/hr) = 1000 mL / 6 hr

Infusion rate (mL/hr) = 166.67 mL/hr

Step 2: Calculate the flow rate in gtt/min:

Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr

Flow rate (gtt/min) = (166.67 mL/hr x 10 gtt/mL) / 60 min/hr

Flow rate (gtt/min) = 1666.7 gtt/hr / 60 min/hr

Flow rate (gtt/min) = 27.78 gtt/min

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 28 gtt/min

Correct Answer is B

Explanation

Given:

Ordered dose of amoxicillin: 300 mg

Concentration of amoxicillin oral solution: 250 mg/5 mL

Step 1: Set up the proportion:

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

Step 2: Substitute the values:

300 mg / Volume = 250 mg/5 mL

Step 3: Solve for the unknown volume:

Volume = 300 mg / (250 mg/5 mL)

Volume = 300 mg x (5 mL / 250 mg)

Volume = 6 mL
