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 D

Explanation

Rationale:

Ordered Dose:

The prescription is for 12 mg of Celestone Soluspan (betamethasone) IM every 24 hours for 2 doses.

Available Dose (from label): The vial contains 6 mg/mL.

Dosage Calculation: Using the formula:

Volumetoadminister(mL) = Availableconcentration(mg/mL) / Ordereddose(mg)

Volumetoadminister = 12mg / 6mg/mL = 2 mL

Administration Route:

The order specifies IM (intramuscular) administration, aligning with the label instructions.

Thus, 2 mL IM is the correct dosage to administer.

Correct Answer is A

Explanation

Given:

Volume of fluid: 100 mL

Infusion time: 45 minutes

Step 1: Convert infusion time to hours:

Infusion time (hr) = 45 min / 60 min/hr

Infusion time (hr) = 0.75 hr

Step 2: Calculate the infusion rate in mL/hr:

Flow rate (mL/hr) = Volume (mL) / Infusion time (hr)

Flow rate (mL/hr) = 100 mL / 0.75 hr

Flow rate (mL/hr) = 133.3333333 mL/hr

Step 3: Round to the nearest whole number:

Flow rate (mL/hr) ≈ 133 mL/hr
