HESI RN
HESI Pediatric Practice Exam
1. A 6-year-old child with a history of asthma is brought to the clinic with complaints of wheezing and shortness of breath. The nurse notes that the child is using accessory muscles to breathe. What should the nurse do first?
- A. Administer a bronchodilator
- B. Obtain a peak flow reading
- C. Apply oxygen
- D. Perform a complete respiratory assessment
Correct answer: A
Rationale: Administering a bronchodilator is the initial priority as it helps open the child's airways, reducing the wheezing and shortness of breath. This intervention aims to provide immediate relief and improve the child's respiratory distress. Obtaining a peak flow reading or applying oxygen may be necessary after administering the bronchodilator, but the priority is to address the acute symptoms of wheezing and shortness of breath first. Performing a complete respiratory assessment can be done after the immediate intervention of administering the bronchodilator to further evaluate the child's respiratory status.
2. A client in labor who received epidural anesthesia experiences a sudden drop in blood pressure. What action should the nurse take first?
- A. Administer oxygen via nasal cannula.
- B. Administer an intravenous fluid bolus.
- C. Prepare the client for an emergency cesarean section.
- D. Place the client in a lateral position.
Correct answer: D
Rationale: In a client experiencing a sudden drop in blood pressure after epidural anesthesia, the first action the nurse should take is to place the client in a lateral position. This position helps improve venous return and cardiac output by relieving aortocaval compression. Administering oxygen via nasal cannula may be necessary if the client shows signs of respiratory distress, but it is not the first priority in this situation. Administering an intravenous fluid bolus can help stabilize blood pressure, but repositioning the client takes precedence. Preparing the client for an emergency cesarean section is not indicated solely based on a sudden drop in blood pressure after epidural anesthesia; this step would be considered if other complications arise.
3. A client with an electrical burn on the forearm asks the nurse why there is no feeling of pain from the burn. During the dressing change, the nurse determines that the burn is dry, waxy, and white. What information should the nurse provide this client?
- A. The depth of tissue destruction is minor
- B. Pain is interrupted due to nerve compression
- C. The full thickness burn has destroyed the nerves
- D. Second-degree burns are not usually painful
Correct answer: C
Rationale: The correct answer is C: 'The full thickness burn has destroyed the nerves.' In full thickness burns, also known as third-degree burns, the nerve endings are destroyed, leading to a lack of pain sensation at the site of the burn. The description of the burn as dry, waxy, and white indicates a full thickness burn. Choices A, B, and D are incorrect because they do not explain the absence of pain in full thickness burns. Choice A is incorrect as a full-thickness burn involves significant tissue destruction. Choice B is incorrect because nerve compression would not explain the lack of pain in this context. Choice D is incorrect because second-degree burns, unlike full-thickness burns, are painful due to nerve endings being intact.
4. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be monitored closely?
- A. Serum potassium
- B. Hemoglobin
- C. Serum sodium
- D. White blood cell count
Correct answer: A
Rationale: The correct answer is A: Serum potassium. When a client with chronic kidney disease is undergoing erythropoietin therapy, monitoring serum potassium levels is crucial. Erythropoietin can stimulate red blood cell production, which may lead to an increase in potassium levels, predisposing the client to hyperkalemia. Monitoring serum potassium levels helps in early detection of hyperkalemia and appropriate intervention. Choices B, C, and D are incorrect because although hemoglobin, serum sodium, and white blood cell count are important parameters to monitor in various clinical conditions, they are not specifically associated with erythropoietin therapy in chronic kidney disease.
5. A client with a history of coronary artery disease is admitted with chest pain. Which finding requires immediate intervention?
- A. Heart rate of 90 beats per minute.
- B. Blood pressure of 130/80 mm Hg.
- C. Respiratory rate of 20 breaths per minute.
- D. Chest pain radiating to the left arm.
Correct answer: D
Rationale: The correct answer is D. Chest pain radiating to the left arm can be a sign of myocardial infarction (heart attack) and requires immediate intervention. This symptom is known as a classic presentation of a heart attack and warrants urgent medical attention to prevent further cardiac damage. Choices A, B, and C are not directly indicative of an acute cardiac event and may not require immediate intervention in this scenario. While heart rate, blood pressure, and respiratory rate are important vital signs to monitor, they do not specifically indicate the urgency associated with chest pain radiating to the left arm in a patient with a history of coronary artery disease.
