Sample Questions

1.
The nurse is caring for a patient in end-stage renal failure and anemia. What is the cause of this patient’s anemia?
A)
Low serum iron levels
B)
Low erythropoietin levels
C)
Inadequate oxygenation of tissue
D)
Lack of B12 and folic acid intake
Ans:
B

Feedback:

Anemia can occur if erythropoietin levels are low. This is seen in association with renal failure, when the kidneys are no longer able to produce erythropoietin. Low iron levels, hypoxia, and vitamin deficiency are not likely to be the primary cause of anemia in a patient with kidney failure.

2.
A 2-year-old child weighing 32 pounds is to take ferrous sulfate (Feosol) 6 mg/kg/d PO. How many milligram will the child receive per dose?
A)
47 mg
B)
67 mg
C)
87 mg
D)
107 mg
Ans:
C

Feedback:

The nurse will administer 87 mg per dose. The child’s weight is first converted to kilograms by dividing 32 by 2.2, or 32/2.2 = 14.5 kg. Next, calculate the dose by multiplying weight times mg/kg/d or 14.5 × 6 = 87 mg.

3.
A nurse caring for a 28-year-old woman with renal failure is to start the patient on epoetin alfa therapy for iron replacement. What will the nurse assess before initiating therapy?
A)
Weight
B)
Last menstrual period
C)
Intake and output (I & O) for a 24-hour period
D)
Blood type
Ans:
B

Feedback:

The use of epoetin alfa is not recommended during pregnancy or lactation because of potential adverse effects to the fetus or baby. It is important to determine that the patient is not pregnant before drug therapy has started so the nurse would assess when the patient last menstruated. The patient’s weight, I & O, and blood type are not important factors in determining whether the drug can be used.

4.
The nurse improves patient compliance with the drug regimen of epoetin alfa by providing what?
A)
An appointment card for each drug administration day
B)
A calendar to mark the days of the week the drug is to be administered
C)
A referral for community transportation
D)
The telephone number of the pharmacy where the medication can be purchased
Ans:
B

Feedback:

The nurse should provide the patient with a calendar with the days the drug is to be administered marked clearly to remind her when the dose is due. The patient can be taught to self-administer the drug so there is no need for an appointment or arranging transportation. The patient can use her choice of pharmacy and would not need the telephone number.

5.
A patient who has anemia and a severe GI absorption disorder has been ordered iron dextran (INFeD). What is the most appropriate nursing diagnosis for the patient related to the administration of this drug?
A)
Acute pain related to drug administration
B)
Deficient knowledge regarding drug therapy
C)
Risk for injury related to CNS effects
D)
Disturbed body image related to drug staining of teeth
Ans:
A

Feedback:

Iron dextran is a parenteral form of iron. It is given intramuscularly and must be given by the Z-track method. It can be very painful. Certainly, deficient knowledge and risk for injury are appropriate diagnoses for this patient but would not be related to the administration of the drug. Because this medication is not given orally, tooth staining would not be a concern.
