Question 1

To select a vein for an initial IV site,the best place to begin in a left-handed patient would be the:

Accepted Answer

Unless other reasons are identified,IVs should be started in the most distal portion of the nondominant arm or hand.

Question 2

The nurse explains that a major advantage of IV therapy is that drugs administered via the IV route:

Accepted Answer

Patients who receive IV medications can be better ensured of a more constant therapeutic blood level.

Question 3

Using an IV infusion system that delivers 60 drops/ml,the nurse hangs a 500-ml bag of normal saline (NS)at 8 AM.The physician has ordered a rate of 20 ml/hr.The nurse will set the roller clamp to deliver:

Accepted Answer

20 ml (amount to be infused in 1 hr)´ 60 gtts = 1200 gtts/hr.1200 gtts ¸ 60 min in 1 hr = 20 gtts/min.This roller clamp is an old method to determine rates,but in the case of a nonavailability of electronic delivery devices,it is a good thing to know.

Question 4

The nurse assesses an area where an IV had been recently changed.The area has redness,swelling,and warmth,which are characteristics of:

Accepted Answer

IV sites may show signs of inflammation or infection or both after the IV has been removed.

Question 5

An older adult patient is assessed by the nurse as showing signs of fluid volume excess,which are:

Accepted Answer

Fluid volume excess in the circulating volume can overload the heart's ability to handle the excess blood.The excess fluid can leak into the pulmonary tree,causing shortness of breath and rales.

Question 6

The nurse charts signs of infected phlebitis as:

Accepted Answer

Infection causes redness,warmth,and drainage from the IV site.Red streaks following the path of the vein may be visible.

Question 7

The nurse is carefully checking IV sites for signs of infiltration,which are:

Accepted Answer

IV fluid in the immediate tissues causes pain and swelling of the adjacent tissues.

Question 8

In making out the assignment for the evening shift,the licensed practical nurse (LPN)is careful to assign IV rounds to be performed:

Accepted Answer

IV checks every hour,made by a nurse,ensure maintenance of a proper rate,infusion condition,and complication detection.

Question 9

The nurse explains that caloric sources in IVs come from:

Accepted Answer

Dextrose is sugar and the source of calories.

Question 10

Using an IV infusion system that delivers 60 drops/ml,the nurse hangs a 1000-ml bag of 5% dextrose in water (D?W),which the physician has ordered to infuse at 80 ml/hr.It is now 10 AM.The nurse anticipates that the IV will need to be changed at:

Accepted Answer

1000 ml (whole volume)¸ 80 ml (volume infused per hour)= 12.5 hours.10:00 AM + 12.5 hours = 10:30 PM.

Question 11

An IV administration of doxycyclin (Vibramycin)has extravagated.After stopping the IV,the nurse should:

Accepted Answer

Because doxycyclin is a vesicant,the physician should be notified.The IV should be restarted to maintain the drug at a therapeutic level.

Question 12

The physician orders a hypertonic IV for an extremely edematous patient.The nurse anticipates that the IV preparation will be:

Accepted Answer

D?W in 0.25 NS is hypotonic.D?W in NA and lactated Ringer's solution is isotonic; 10% glucose is hypertonic.

Question 13

When removing a central catheter,the nurse should instruct the patient to:

Accepted Answer

The patient is instructed to take a breath and bear down to prevent air from entering the bloodstream as the catheter is removed.

Question 14

When the nurse is to give a piggyback IV push medication to a patient who is receiving a continuous infusion,the nurse injects the medication:

Accepted Answer

An IV push is to be administered through the port closest to the patient.

Question 15

The nurse is choosing an IV cannula for an older adult patient and will choose the smallest size that will deliver the appropriate fluid,which is a cannula of:

Accepted Answer

The inside diameter,called the gauge,is expressed in reverse numerical order.

Question 16

The physician orders an infusion of 1000 ml of 5% dextrose in 0.45 NS to be completed in 8 hours.The IV delivery system's drop factor is 20 gtts.The nurse should set the electronic infusion pump to deliver ______________ ml/hr?

Accepted Answer

Whole volume (1000 ml)divided by number of hours (8)= 125 ml/hour.Volume per hour (125 ml)´ 8 hours = 1000 ml.

Question 17

In an assessment of a patient who has been receiving intravenous (IV)fluids for the last 6 hours,the nurse finds that the pulse is now bounding,the blood pressure is more than 15 mm Hg higher than the last reading,and pedal edema has developed.The nurse evaluates these signs as associated with:

Accepted Answer

Excess fluid volume accounts for the changes in the vital signs.

Question 18

The nurse has a patient with a tunneled central line with a triple-lumen catheter.The insertion site is covered by an occlusive dressing with yesterday's date.The nurse is to give an IV drug through the central line.The nurse would initially:

Accepted Answer

Checking the drug for the proper dilution is essential.The dressing is not due to be changed.Drawing 3 ml of blood for site placement is excessive.Only two of the ports,which are color-coded,are to be used for drug,fluid,or blood administration.

Question 19

As part of a written standard protocol for the unit,the nurse adds that irrigation of an occluded cannula is not recommended.The rationale against performing this procedure is that it may:

Accepted Answer

A cannula may be occluded because a clot has formed against the end of the shaft.By irrigating it,the clot is forced into the bloodstream.

Question 20

The patient is to receive ampicillin (Unasyn)IV piggyback in 100 ml of fluid every 8 hours.The main IV of D?W is running at 80 ml/hr and is on time.The nurse's responsibility is to calculate the total 24-hour intake.At the end of the 24-hour shift,how much IV intake will the nurse document that the patient has received?

Accepted Answer

80 ml/hr ´ 24 hr = 1920 ml; 100 ml ´ 3 = 300 ml.Therefore 1920 ml + 300 ml = 2220 ml in 24 hours.
