Item 1
Question: A client who has been NPO for 3 days is receiving an infusion of
Dextrose 5% in 0.45% Sodium chloride (D5 1/2 NS) with potassium chloride
(KCl) 20 mEq at 83 ml/hour. The client's 8-hour urine output is 400 ml, BUN
is 15 mg/dl, lungs are clear bilaterally, serum glucose is 110 mg/dl, and
serum potassium is 3.7 mEq/L. Which action should the nurse implement?
A) Increase the IV infusion rate to replace the urine output.
B) Notify the healthcare provider of the low urine output.
C) Document in the medical record that these normal findings are expected
outcomes.
D) Administer potassium chloride IV push.
Correct Answer: C
Rationale: All results are within normal range (BUN 10-20 mg/dl, serum
glucose 70-110 mg/dl, serum potassium 3.5-5.0 mEq/L). The other actions
are not indicated as there are no abnormal findings.
,Item 2
Question: The nurse is preparing the change-of-shift report for a client
who has a 265 ml secondary infusion that was started 2 hours ago at a rate
of 85 ml/hour via an infusion pump. The nurse should report that how
many ml remain to be infused?
A) 180 ml
B) 95 ml
C) 265 ml
D) 170 ml
Correct Answer: B
Rationale: 85 ml/hour × 2 hours = 170 ml infused. 265 ml - 170 ml = 95 ml
remaining.
Item 3
Question: A child scheduled for a kidney transplant receives a prescription
for basiliximab (Simulect) 20 mg IV 2 hours prior to surgery. The medication
is available in a 20 mg vial reconstituted with 5 ml sterile water and
administered as a secondary infusion of normal saline 50 ml to be infused
over 30 minutes. The nurse should program the infusion pump to deliver
how many ml/hour?
A) 50 ml/hour
B) 100 ml/hour
, C) 110 ml/hour
D) 55 ml/hour
Correct Answer: C
Rationale: Total volume = 5 ml (reconstituted medication) + 50 ml (normal
saline) = 55 ml. To infuse over 30 minutes (0.5 hours): 55 ml ÷ 0.5 hours =
110 ml/hour.
Item 4
Question: A client with Mycobacterium avium complex (MAC) is receiving
an infusion of D5W with amikacin (Amikin) 0.572 grams/100 ml every 12
hours. The nurse prepares the dose using a vial labeled "250 mg/ml." How
many ml should the nurse add to the infusion?
A) 2.3 ml
B) 0.23 ml
C) 22.9 ml
D) 5.72 ml
Correct Answer: A
Rationale: Convert 0.572 grams to mg: 0.572 × 1000 = 572 mg. Then 572
mg ÷ 250 mg/ml = 2.288 ml (rounded to 2.3 ml).
