Question

Chapter 1:

A patient is admitted with aortic valve insufficiency. A murmur is auscultated during the assessment and reported to be a grade of IV/VI. Convert the Roman numbers to describe the murmur to Arabic numbers.  

Chapter 2:

A nurse is recording the fluid intake for a client. The following questions pertain to this situation:

A. The nurse notes that the client has drank half of the water in the water pitcher. The pitcher holds 900 mL of water. How many milliliters would the nurse record?

B.  The nurse notes that ¾ of the intravenous (IV) fluids have infused in the past 12 hours. The IV bag contained 1000 mL of fluid at the beginning of the shift. How many milliliters would the nurse record for the IV intake?

C. A nurse has calculated the volume of two medications to be administered by injection. The first medication has a volume of ½ mL, and the second medication has a volume of ¾ mL. What is the total volume of medication?

Chapter 3:

A nurse is preparing a patient for surgery. A preoperative medication is ordered. The following questions pertain to the situation.

A. A nurse has calculated the volume of two medications to administer by injection. The first medication has a volume of 1/2 mL, and the second medication has a volume of 3/4 mL.

The medications will be combined in one syringe. The syringe is calibrated in 0.1-mL increments, so the total volume must be converted from a fraction into a decimal. What is the total volume of medication?

B.   Adult doses are usually rounded to the nearest tenth. Round 1.25 mL to the nearest tenth.

Chapter 4:

A nurse is caring for a patient with a blood clot in the right arm. The following questions pertain to this situation.

A. The pharmacy delivers a heparin bag with 25,000 units of heparin in 250 mL of 0.9% normal saline (NS). How many units of heparin are in 1 mL of NS?

B.  A patient is to take 60 mEq of potassium chloride in six equal doses. How many mEq of potassium will the nurse administer with each dose?

  Chapter 5:

A. The amp of D₅₀ contains a total of 50 mL. Calculate the number of grams contained in the amp of D_50.

     B. A nurse is writing orders she received from the physician over the telephone. The following questions pertain to this situation: The nurse receives an order for one-half of a milligram for a medication. How should the nurse write one-half?

Answer 1

A.

Chapter 1 :

We know V is roman number equivalent of 5 and I is the roman equivalent of 1. So,

Chapter 2 :

A) Total water that can be held =

Amount client drank =

B) The required solution is

C) We need to add the two fractions. So, we get .

And the answer will be .

Chapter 3:

A) As seen above, the total volume will be . Converting into decimal, that is dividing 5 by 4, we get .

B) Rounding to nearest tenth, we will get .

Chapter 4:

A) 250 mL has 25,000 units.

So, 1 mL will have 25,000/250 units, that is 100 units.

B) Let us consider, potassium administered in one dose is x.

Then 6x=60.

That is, .

So, 10 mEq of potassium is administered with each dose.

Chapter 5:

A) 1 mL = 1 gram.

So, 50 mL = 50 grams.

B) The nurse can write it as 0.5 mg.
