A patient asks the nurse to explain the medications they are taking. Which medication would be considered an angiotensin converting enzyme inhibitor?

A.

simvastatin

B.

losartan

C.

Quinapril

D.

Metoprolol

Answer and Explanation

The Correct Answer is C

A) Simvastatin:
Simvastatin is a medication used to lower cholesterol levels by inhibiting HMG-CoA reductase, an enzyme involved in the production of cholesterol in the liver. It is not an angiotensin-converting enzyme (ACE) inhibitor. Therefore, it does not have a direct effect on blood pressure or the renin-angiotensin system.

B) Losartan:
Losartan is an angiotensin II receptor blocker (ARB), not an ACE inhibitor. Like ACE inhibitors, ARBs are used to treat conditions like hypertension and heart failure, but they work differently by blocking the receptors that angiotensin II binds to, rather than inhibiting the enzyme that converts angiotensin I to angiotensin II.

C) Quinapril:
Quinapril is an ACE inhibitor. ACE inhibitors block the enzyme angiotensin-converting enzyme, which converts angiotensin I into angiotensin II, a potent vasoconstrictor. By inhibiting this conversion, ACE inhibitors like quinapril help lower blood pressure, reduce strain on the heart, and treat conditions like hypertension and heart failure.

D) Metoprolol:
Metoprolol is a beta-blocker, not an ACE inhibitor. It works by blocking beta-adrenergic receptors in the heart, which helps to lower heart rate and blood pressure. It is often used in the management of hypertension, heart failure, and to prevent heart attacks, but it does not affect the renin-angiotensin system like ACE inhibitors.

Correct Answer is B

Explanation

Given:
Volume of fluid: 50 mL
Infusion time: 1 hour (60 minutes)
Drop factor: 15 gtt/mL

Formula:
Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL)

Step 1: Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Volume (mL) / Time (min)
Infusion rate (mL/min) = 50 mL / 60 min
Infusion rate (mL/min) = 0.83 mL/min

Step 2: Calculate the flow rate in gtt/min:
Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)
Flow rate (gtt/min) = 0.83 mL/min x 15 gtt/mL
Flow rate (gtt/min) = 12.5 gtt/min

Step 3: Round to the nearest whole number:
Flow rate (gtt/min) ≈ 13 gtt/min

Correct Answer is C

Explanation

Given:

Ordered dose of Heparin: 100,000 units

Concentration of Heparin: 25,000 units/10 mL

Step 1: Set up the proportion:

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

Step 2: Substitute the values:

100,000 units / Volume = 25,000 units/10 mL

Step 3: Solve for the unknown volume:

Volume = 100,000 units / (25,000 units/10 mL)

Volume = 100,000 units x (10 mL / 25,000 units)

Volume = 40 mL
