HESI Fundamentals Practice Exam Questions
Question 1 of 5
A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?
Correct Answer: B
Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.
Question 2 of 5
A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which intervention should the nurse implement first?
Correct Answer: A
Rationale: Administering regular insulin IV (A) is the initial intervention for a client with diabetic ketoacidosis (DKA) to rapidly reduce blood glucose levels. This is vital in reversing the ketosis and acidosis seen in DKA. Administering IV fluids (B) helps to correct dehydration and electrolyte imbalances. Administering sodium bicarbonate (C) and furosemide (D) may be necessary depending on the client's condition, but insulin administration takes precedence in the management of DKA.
Question 3 of 5
Which assessment data would provide the most accurate determination of proper placement of a nasogastric tube?
Correct Answer: C
Rationale: The most accurate method to confirm the proper placement of a nasogastric tube is by examining a chest x-ray obtained after the tubing was inserted. This visual assessment allows healthcare providers to directly visualize the position of the tube in relation to anatomical landmarks, ensuring it is correctly placed in the stomach. Aspirating gastric contents or hearing air pass may provide some information but are not as definitive as a chest x-ray for confirming placement. Checking the remaining length of tubing is not a reliable method for determining proper placement as it does not indicate where the tip of the tube lies within the body.
Question 4 of 5
While observing an unlicensed assistive personnel (UAP) providing a total bed bath for a confused and lethargic client, the nurse notes the UAP soaking the client's foot in a basin of warm water placed on the bed. What action should the nurse take?
Correct Answer: B
Rationale: The correct action for the nurse to take in this situation is to remind the unlicensed assistive personnel (UAP) to dry between the client's toes completely. Failing to dry between the toes can lead to skin breakdown due to excessive moisture accumulation. Proper drying is essential to maintain skin integrity and prevent complications in the client's care. Removing the basin of water immediately may disrupt the care process and not address the root cause of the issue. Advising about potential skin damage is not as direct and actionable as reminding to dry between the toes. Adding skin cream to the water may not be appropriate without specific orders and can potentially worsen the situation by increasing moisture.
Question 5 of 5
The client is being taught how to perform active range of motion (ROM) exercises. To exercise the hinge joints, which action should the client be instructed to perform?
Correct Answer: B
Rationale: Hinge joints, like the elbow, primarily allow movement in one direction, in this case, bending the arm. The correct action to exercise hinge joints is to bend the arm by flexing the ulnar to the humerus. This movement specifically targets the hinge joint and promotes its range of motion. Choices A, C, and D involve movements that do not specifically target hinge joints. Tilt the pelvis involves the ball-and-socket joints of the hip, turning the head involves the pivot joint of the neck, and extending the arm and rotating it in circles involve multiple joints including ball-and-socket and pivot joints.
