ICC NATIONAL STANDARD MASTER
ELECTRICIAN EXAMINATION QUESTIONS
AND CORRECT ANSWERS.
1. A client with a history of heart failure is prescribed furosemide. Which of
the following laboratory values should the nurse monitor most closely?
A. Serum sodium
B. Serum potassium
C. Serum calcium
D. Serum magnesium
Answer: B. Serum potassium
Rationale: Furosemide is a loop diuretic that inhibits sodium and chloride
reabsorption in the ascending loop of Henle, leading to increased excretion of
potassium. Hypokalemia is a significant adverse effect that can lead to cardiac
dysrhythmias.
2. A nurse is preparing to administer a blood transfusion to a client. Which IV
solution should be used to prime the tubing?
A. Dextrose 5% in water
B. Lactated Ringer’s
C. 0.9% Normal Saline
D. Dextrose 5% in 0.45% saline
Answer: C. 0.9% Normal Saline
,Rationale: 0.9% Normal Saline is the only isotonic solution compatible with
blood products. Dextrose solutions can cause hemolysis and agglutination of
red blood cells, and Lactated Ringer's contains calcium, which can cause
clotting if mixed with blood.
3. A client is prescribed warfarin. Which of the following laboratory values is
the best indicator of therapeutic effectiveness?
A. Platelet count
B. aPTT
C. INR
D. Bleeding time
Answer: C. INR
Rationale: Warfarin affects the extrinsic pathway of the coagulation cascade
by inhibiting vitamin K-dependent clotting factors. The International
Normalized Ratio (INR) is the standardized test used to monitor warfarin
therapy, with a typical therapeutic goal of 2.0-3.0.
4. A nurse is caring for a client post-operative day one following a total hip
arthroplasty. Which of the following interventions is a priority to prevent
dislocation?
A. Maintain the client in a high-Fowler's position.
B. Keep a pillow between the client's legs.
C. Ambulate the client four times a day.
D. Perform passive range-of-motion exercises.
Answer: B. Keep a pillow between the client's legs.
Rationale: Keeping an abduction pillow or a pillow between the legs prevents
adduction and internal rotation, which are the primary movements that can
cause dislocation of a new hip prosthesis.
,5. A client with a nasogastric tube to low intermittent suction has a potassium
level of 3.2 mEq/L. Which of the following is the priority nursing action?
A. Administer a potassium supplement as prescribed.
B. Assess for muscle cramps and weakness.
C. Monitor the client's cardiac rhythm.
D. Document the finding as the only action.
Answer: C. Monitor the client's cardiac rhythm.
Rationale: While all options are relevant, hypokalemia (K+ < 3.5) can cause
fatal cardiac dysrhythmias. Monitoring the cardiac rhythm is the priority to
ensure client safety.
6. A client with diabetes mellitus type 1 is experiencing diaphoresis,
tachycardia, and confusion. Which of the following should the nurse
administer first?
A. 50% Dextrose IV push
B. Glucagon IM
C. Orange juice orally
D. 0.9% Normal Saline IV
Answer: C. Orange juice orally
Rationale: The client is showing signs of hypoglycemia. If the client is
conscious and able to swallow, oral glucose is the first line of treatment.
Orange juice is a fast-acting simple sugar.
7. A nurse is performing a sterile dressing change. Which of the following
actions demonstrates proper sterile technique?
A. Opening the sterile kit away from the body.
B. Holding the sterile objects below waist level.
, C. Pouring sterile solution onto the sterile field from a distance of 6 inches.
D. Placing the sterile drape with the shiny side facing up.
Answer: C. Pouring sterile solution onto the sterile field from a distance of 6
inches.
Rationale: Pouring from a height of 4-6 inches allows the solution to flow
freely without contaminating the lip of the bottle. Opening the kit away from
the body, holding objects above waist level, and placing the drape shiny side
down (fluid-resistant side) are correct techniques.
8. A client is admitted with a diagnosis of myocardial infarction. Which of the
following medications should the nurse administer to relieve chest pain and
reduce myocardial oxygen demand?
A. Nitroglycerin sublingual
B. Morphine sulfate IV
C. Aspirin orally
D. Oxygen via nasal cannula
Answer: A. Nitroglycerin sublingual
Rationale: Nitroglycerin is a vasodilator that reduces preload and afterload,
decreasing myocardial oxygen demand and relieving chest pain. It is the first-
line medication for angina.
9. The parent of a 4-year-old child calls the pediatric clinic and reports that
the child has ingested a small amount of a household cleaner. Which of the
following is the nurse's priority response?
A. "Administer ipecac syrup to induce vomiting immediately."
B. "Call the Poison Control Center and follow their instructions."
C. "Bring the child to the clinic right away."
D. "Give the child a glass of milk to dilute the poison."
