HESI RN
HESI Pediatric Practice Exam
1. A child with a fever of 39°C (102.2°F) and a sore throat is brought to the clinic. The practical nurse suspects the child has streptococcal pharyngitis. Which diagnostic test should the practical nurse prepare the child for?
- A. Rapid antigen detection test.
- B. Throat culture.
- C. Complete blood count (CBC).
- D. Chest X-ray.
Correct answer: A
Rationale: A rapid antigen detection test is the appropriate diagnostic test for suspected streptococcal pharyngitis. This test is commonly used due to its quick results, helping in the prompt diagnosis and appropriate treatment of the condition. It specifically detects the presence of streptococcal antigens in the throat, aiding in confirming the diagnosis and guiding the healthcare provider in determining the most suitable treatment plan. Throat culture (Choice B) is a confirmatory test but is not as rapid as the rapid antigen detection test. Complete blood count (Choice C) and Chest X-ray (Choice D) are not specific tests for streptococcal pharyngitis and would not aid in confirming the diagnosis.
2. A client is recovering after a nephrostomy tube was placed 6 hours ago. The nurse notes drainage in the tube has decreased from 40 mL/hr to 12 mL over the last hour. Which action should the nurse take?
- A. Document the finding in the client’s record.
- B. Evaluate the tube as working in the hand-off report.
- C. Clamp the tube in preparation for removing it.
- D. Assess the client’s abdomen and vital signs.
Correct answer: D
Rationale: The correct action for the nurse to take in this situation is to assess the client’s abdomen and vital signs. The nephrostomy tube should have a consistent amount of drainage, and a decrease may indicate obstruction. Before notifying the provider, the nurse must assess the client for pain, distention, and changes in vital signs. This assessment is crucial to gather essential information to report accurately. Documenting the finding without further assessment may delay necessary intervention. Evaluating the tube as working in the hand-off report or clamping the tube prematurely are not appropriate actions and could lead to complications if there is an obstruction.
3. The nurse is preparing a teaching plan for a client diagnosed with asthma. The primary purpose of the plan is to
- A. Prevent respiratory infections
- B. Prevent airway inflammation
- C. Maintain an open airway
- D. Avoid allergens that trigger attacks
Correct answer: D
Rationale: Avoiding allergens that trigger asthma attacks is crucial in managing the condition and preventing exacerbations. While preventing respiratory infections and maintaining an open airway are important aspects of asthma management, the primary focus of the teaching plan is to help the client identify and avoid allergens that could trigger asthma attacks. This proactive approach can significantly reduce the frequency and severity of asthma symptoms.
4. A 67-year-old male client has been complaining of sleeping more, increased urination, anorexia, weakness, irritability, depression, and bone pain that interferes with his ability to go outdoors. Based on these assessment findings, Nurse Richard would suspect which of the following disorders?
- A. Diabetes mellitus
- B. Diabetes insipidus
- C. Hypoparathyroidism
- D. Hyperparathyroidism
Correct answer: D
Rationale: The symptoms described in the scenario, such as bone pain, increased urination, anorexia, and weakness, are indicative of hyperparathyroidism. In hyperparathyroidism, there is an excess of parathyroid hormone leading to increased calcium levels, which can result in bone pain and various systemic effects. Choices A, B, and C are incorrect because they do not align with the symptoms presented by the client. Diabetes mellitus primarily presents with polyuria, polydipsia, and hyperglycemia. Diabetes insipidus manifests as polyuria and polydipsia with dilute urine. Hypoparathyroidism usually presents with hypocalcemia, causing symptoms like muscle cramps, tingling sensations, and seizures.
5. Which task can the registered nurse (RN) caring for a critically ill patient with multiple IV lines delegate to an experienced licensed practical/vocational nurse (LPN/LVN)?
- A. Administer IV antibiotics through the implantable port.
- B. Monitor the IV sites for redness, swelling, or tenderness.
- C. Remove the patient’s nontunneled subclavian central venous catheter.
- D. Adjust the flow rate of the 0.9% normal saline in the peripheral IV line.
Correct answer: B
Rationale: An experienced LPN/LVN can monitor IV sites for signs of infection because it falls within their education, experience, and scope of practice. Administering IV antibiotics through an implantable port, adjusting infusion rates, and removing central catheters are tasks that require RN level education and scope of practice. These activities involve a higher level of assessment, critical thinking, and potential complications that are typically within the RN's domain.
