HESI Fundamentals Practice Exam Questions
Question 1 of 5
The client is receiving discharge teaching for a new diagnosis of asthma. Which statement by the client indicates a need for further teaching?
Correct Answer: B
Rationale: The statement 'I should avoid using my inhaler unless I am having an asthma attack' (B) indicates a need for further teaching. It is important for clients to use their inhaler as prescribed, which may include regular use to prevent asthma attacks. Choice A is correct because using the inhaler when feeling short of breath can help manage asthma symptoms. Choice C is also correct as using the inhaler before exercise can prevent exercise-induced symptoms. Choice D is correct as rinsing the mouth after using the inhaler helps prevent oral thrush, a potential side effect of inhaled corticosteroids. Therefore, option B is the most concerning statement that needs clarification.
Question 2 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 3 of 5
The healthcare provider is assessing a client with a diagnosis of pneumonia. Which assessment finding is most concerning?
Correct Answer: D
Rationale: A respiratory rate of 28 breaths per minute (D) is most concerning because it indicates respiratory distress and requires immediate intervention. While coarse crackles (A), fever (B), and productive cough (C) are common findings in pneumonia, a high respiratory rate signifies a more severe condition that needs prompt attention to prevent respiratory failure. Monitoring the respiratory rate is crucial in assessing the severity of respiratory distress in pneumonia, as it can rapidly progress to respiratory failure if not managed promptly.
Question 4 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 5 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.
