HESI RN
HESI Fundamentals Practice Exam
1. A client with a history of coronary artery disease (CAD) is admitted with chest pain. Which intervention should the nurse implement first?
- A. Administer sublingual nitroglycerin
- B. Obtain a 12-lead electrocardiogram (ECG)
- C. Apply oxygen via nasal cannula
- D. Initiate continuous cardiac monitoring
Correct answer: C
Rationale: In a client with a history of coronary artery disease (CAD) experiencing chest pain, the priority intervention for the nurse to implement first is to apply oxygen via nasal cannula. Oxygenation is crucial to ensure adequate oxygen supply to the tissues and the heart. This intervention takes precedence over administering sublingual nitroglycerin, obtaining an ECG, or initiating continuous cardiac monitoring. While these interventions are important, ensuring adequate oxygenation is the initial priority in the management of a client with chest pain.
2. The nurse is administering intravenous fluids to a dehydrated patient. On the second day of care, the patient's weight has increased by 2.25 pounds. The nurse would expect that the patient's fluid intake has
- A. equaled urine output.
- B. exceeded urine output by 1 L.
- C. exceeded urine output by 2.5 L.
- D. exceeded urine output by 3 L.
Correct answer: B
Rationale: A weight gain of 1 kg, or approximately 2.2 to 2.5 lb, is generally equivalent to 1 liter (L) of fluid retained by the body. In this case, the patient's weight gain of 2.25 pounds suggests an excess fluid retention of approximately 1 liter, indicating that the patient's fluid intake has exceeded urine output by 1 liter. Choices C and D are incorrect as they overestimate the fluid excess based on the patient's weight gain. Choice A is incorrect as it implies an exact balance between fluid intake and urine output, which is not reflected in the given weight increase.
3. 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.
4. While auscultating the lung sounds of a 5-year-old Chinese boy who recently completed antibiotic therapy for pneumonia, the nurse notices symmetrical, round, bruise-like blemishes on his chest. What action is best for the nurse to take?
- A. Identify the antibiotics used for treating the pneumonia.
- B. Inquire about the use of alternative treatment methods.
- C. Ask the parents if the child has been in a recent accident.
- D. Report suspected child abuse to the authorities.
Correct answer: B
Rationale: Inquiring about the use of alternative treatment methods is essential to understand cultural practices and provide holistic care. It allows the nurse to gather more information about the blemishes and potentially uncover traditional or alternative healing approaches that the family may have used. This approach demonstrates cultural sensitivity and a comprehensive assessment before making assumptions or taking further actions. Identifying the antibiotics used for treating pneumonia (Choice A) is not immediately necessary in this context as the focus is on the blemishes. Asking about a recent accident (Choice C) assumes a traumatic cause without evidence. Reporting suspected child abuse (Choice D) is premature without further assessment or evidence of abuse.
5. The nurse is caring for a client with a nasogastric tube. Which of the following interventions is a priority to maintain client safety?
- A. Flush the tube with water every 4 hours
- B. Check the tube placement before each feeding
- C. Secure the tube to the client's nose with tape
- D. Keep the head of the bed elevated at 30 degrees
Correct answer: B
Rationale: Verifying the correct placement of a nasogastric tube before each feeding is essential to prevent aspiration and ensure that the tube is properly positioned in the stomach or intestine. This action is a priority to maintain client safety. Flushing the tube with water every 4 hours is important for tube patency but is not the priority over verifying placement. Securing the tube with tape and keeping the head of the bed elevated are crucial but are considered secondary measures compared to confirming the correct tube placement.
