3.A liter of D5W (dextrose 5% in water) is ordered to be given over a 12-hour period. The infusion tubing is calibrated so that 1 mL is 15 drops of fluid. In drops per minute, what should the flow rate be?

a. 125
b. 83
c. 21
d. 30

ANS: C

Feedback
A This answer is incorrect (125 drops/min would be an infusion rate of nearly 6 L per 12-hour period).
B This answer is incorrect (83 is the number of mL per hour for the 12-hour period).
C 1000 mL/12 hours = 83 mL/hr

83 mL/60 min = 1.4 mL/min

1.4 mL/min  15/drops/mL = 21 drops/min
D This answer is incorrect (30 drops/min would be an infusion rate of approximately 2 L per 12-hour period).

DIF: Cognitive Level: Remember REF: Page 36

4.What is the site of choice for an intramuscular injection in a patient younger than 3 years of age?

a. Deltoid
b. Vastus lateralis
c. Gluteus maximus
d. Abdomen

ANS: B

Feedback
A The leg muscles are larger than the muscles in the arm.
B The vastus lateralis is preferred because the muscles in the gluteus are not yet well developed in small children.
C The muscles in the gluteus are not yet well developed in small children.
D The muscles in the abdomen are not used for injection sites.

DIF: Cognitive Level: Remember REF: Page 33 and 35 (Fig. 5-8)

5.How long will it take for an antibiotic infusion of 50 mL to complete at a rate of 30 drops/min in infusion tubing calibrated at 60 drops/mL?

a. 5 minutes
b. 1 hour
c. 100 minutes
d. 3 hours

ANS: C

Feedback
A This answer is incorrect (5 minutes’ infusion would be at a rate of 600 drops/min).
B This answer is incorrect (60 minutes’ infusion would be at a rate of 50 drops/min).
C 30 drops = 0.5 mL/min

50 mL/0.5 = 100 minutes
D This answer is incorrect (3 hours’ infusion would be an infusion rate of 17 drops/min).

6.Before injecting medication by subcutaneous or intramuscular routes, the syringe should be:

7.Where is the proper injection site into the deltoid muscle located?

a. Midway between the shoulder and the elbow
b. At the largest part of the muscle
c. Three fingerbreadths below the acromion process

B Because muscle development varies among individuals, this is not a good basis for deciding where to administer an injection.
C The acromion is the attachment point for the deltoid muscle.
