HESI RN
HESI Fundamentals Practice Exam
1. 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?
- A. Tilt the pelvis forwards and backwards
- B. Bend the arm by flexing the ulnar to the humerus
- C. Turn the head to the right and left
- D. Extend the arm at the side and rotate it in circles
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.
2. The healthcare professional is assessing a client with a diagnosis of peripheral arterial disease (PAD). Which assessment finding is most indicative of this condition?
- A. Dependent rubor.
- B. Absence of hair on the lower legs.
- C. Shiny, thin skin on the legs.
- D. Pain in the legs when walking.
Correct answer: D
Rationale: Pain in the legs when walking (D), known as intermittent claudication, is most indicative of peripheral arterial disease (PAD). While dependent rubor (A), absence of hair (B), and shiny, thin skin (C) are also associated with PAD, they are less specific than intermittent claudication. Intermittent claudication is a hallmark symptom of PAD caused by inadequate blood flow to the legs during exercise, resulting in pain that resolves with rest.
3. The nurse is caring for several patients who are receiving antibiotics. Which order will the nurse question?
- A. Azithromycin (Zithromax) 500 mg IV in 500 mL of fluid
- B. Azithromycin (Zithromax) 500 mg PO once daily
- C. Erythromycin 300 mg IM QID
- D. Erythromycin 300 mg PO QID
Correct answer: C
Rationale: The nurse should question the order for Erythromycin 300 mg IM QID. Erythromycin and other macrolides should not be given intramuscularly because they cause painful tissue irritation. Options A and B are correct routes for Azithromycin, either intravenously or orally. Option D is a correct route for Erythromycin, which is orally.
4. A client is experiencing diarrhea. For which acid-base disorder should the nurse assess the client?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: A
Rationale: When a client experiences diarrhea, the loss of bicarbonate-rich fluids from the body leads to a decrease in the bicarbonate levels in the blood, resulting in metabolic acidosis. Metabolic alkalosis (choice B) is characterized by an increase in bicarbonate levels, which is not typically associated with diarrhea. Respiratory acidosis (choice C) is caused by retention of carbon dioxide, while respiratory alkalosis (choice D) results from excessive exhalation of carbon dioxide, neither of which are directly related to diarrhea. Therefore, the correct answer is metabolic acidosis (choice A) in the context of diarrhea.
5. A patient who is taking a potassium-wasting diuretic for the treatment of hypertension complains of generalized weakness. It is most appropriate for the nurse to take which action?
- A. Assess for facial muscle spasms.
- B. Ask the patient about loose stools.
- C. Suggest that the patient avoid orange juice with meals.
- D. Ask the healthcare provider to order a basic metabolic panel.
Correct answer: D
Rationale: Generalized weakness is a sign of hypokalemia, a potential side effect of potassium-wasting diuretics. By requesting a basic metabolic panel, the nurse can assess the patient's potassium levels. Facial muscle spasms are associated with hypocalcemia, not hypokalemia. Advising the patient to avoid orange juice, which is high in potassium, would be counterproductive if the patient is hypokalemic. Loose stools are typically seen in hyperkalemia, not hypokalemia.
