Question 1
A nurse is preparing to administer intravenous phenytoin to a
client. Which of the following solutions should the nurse use to
flush the IV line before and after administering this medication?
• A. 5% Dextrose in water (D5W)
• B. 0.9% Sodium chloride
• C. Lactated Ringer's solution
• D. 0.45% Sodium chloride
Answer: B
Rationale: Phenytoin is highly incompatible with most
intravenous fluids and will precipitate if mixed with dextrose
,solutions. The nurse must flush the line only with 0.9%
sodium chloride (normal saline) before and after
administration to maintain line patency and prevent crystal
formulation.
Question 2
A nurse is caring for a client who is taking spironolactone for heart
failure. Which of the following laboratory values should the nurse
report to the provider immediately?
• A. Sodium 136 mEq/L
• B. Potassium 5.4 mEq/L
• C. Magnesium 2.0 mEq/L
• D. Calcium 9.5 mg/dL
Answer: B
Rationale: Spironolactone is a potassium-sparing diuretic
that blocks aldosterone receptors in the distal nephron. A
potassium level of 5.4 mEq/L indicates hyperkalemia, which
risks dangerous cardiac dysrhythmias and requires
immediate clinical intervention.
Question 3
A nurse is assessing a client who has a prescription for clozapine
to treat schizophrenia. Which of the following laboratory results is
the priority for the nurse to review before administering the
medication?
• A. Serum creatinine
, • B. Liver function tests
• C. Absolute neutrophil count (ANC)
• D. Fasting blood glucose
Answer: C
Rationale: Clozapine carries a black box warning due to the
high risk of agranulocytosis, a severe and life-threatening
depletion of white blood cells. The absolute neutrophil count
(ANC) must be checked regularly to ensure it is above the
safe baseline threshold before giving the medication.
Question 4
A nurse is reinforcing teaching with a client who is starting a new
prescription for rifampin to treat tuberculosis. Which of the
following side effects should the nurse tell the client to expect?
• A. Orange-red discoloration of bodily fluids
• B. Ringing in the ears and hearing loss
• C. Severe muscle cramping in the lower extremities
• D. Peripheral numbness and tingling
Answer: A
Rationale: Rifampin naturally causes a benign orange-red
discoloration of urine, sweat, saliva, and tears. Clients must
be warned beforehand so they are not alarmed, and they
should avoid wearing soft contact lenses as they can
become permanently stained.
, Question 5
A nurse is evaluating a client who is receiving a continuous
intravenous infusion of heparin for a deep vein thrombosis. Which
of the following laboratory parameters should the nurse monitor to
adjust the heparin dosage?
• A. Prothrombin time (PT)
• B. International Normalized Ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count
Answer: C
Rationale: Continuous IV heparin therapy is monitored and
titrated using the activated partial thromboplastin time
(aPTT) to maintain a therapeutic range of roughly 1.5 to 2.5
times the control value. PT and INR are utilized to track
warfarin therapy.
Question 6
A nurse is providing discharge instructions to a client with a new
prescription for alendronate to treat osteoporosis. Which of the
following instructions should the nurse include?
• A. Take the medication with a full glass of milk at bedtime.
• B. Sit upright for 30 minutes after taking the medication.
• C. Chew the tablet completely before swallowing.
• D. Take the medication immediately after eating a full
breakfast.
