HESI LPN
HESI Fundamental Practice Exam
1. A client with a history of coronary artery disease is experiencing chest pain. What is the priority action for the nurse to take?
- A. Administer oxygen via a nasal cannula.
- B. Measure the client's vital signs.
- C. Obtain a 12-lead ECG.
- D. Encourage the client to use pursed-lip breathing.
Correct answer: A
Rationale: Administering oxygen via a nasal cannula is the priority action for a client experiencing chest pain due to coronary artery disease. Oxygen therapy helps improve oxygenation, reduce myocardial workload, and relieve chest pain by increasing oxygen delivery to the heart muscle. While measuring vital signs, obtaining a 12-lead ECG, and encouraging pursed-lip breathing are important interventions, administering oxygen takes precedence in this situation to address the potential hypoxemia associated with chest pain in a client with a history of coronary artery disease.
2. The nurse is providing oral care to a patient. In which order will the nurse clean the oral cavity, starting with the first area?
- A. Roof of mouth, gums, and inside cheeks
- B. Chewing and inner tooth surfaces
- C. Outer tooth surfaces
- D. Tongue
Correct answer: C
Rationale: The correct sequence for oral care is to clean the outer tooth surfaces first, followed by cleaning the inner tooth surfaces, then the roof of the mouth, gums, and inside cheeks with a toothette. Brushing the tongue should be the final step in the oral care procedure. Therefore, option C is the correct choice. Options A, B, and D are incorrect because they do not follow the correct order for providing oral care to a patient.
3. A client on a telemetry unit is being cared for by a nurse after a myocardial infarction. The client expresses, 'All this equipment is making me nervous.' Which of the following responses should the nurse make?
- A. 'All of this equipment can be frightening.'
- B. 'The equipment is necessary to monitor your condition.'
- C. 'You should try to ignore the equipment.'
- D. 'Try to relax; the equipment is not harmful.'
Correct answer: A
Rationale: Choice A is the most appropriate response as it acknowledges the client's feelings, showing empathy and understanding. It validates the client's experience, which can help reduce anxiety and build rapport. Choice B provides information but may not address the client's emotional needs. Choice C dismisses the client's concerns and does not offer support. Choice D minimizes the client's feelings and may not effectively address their anxiety.
4. The client is advised to take dexamethasone (Decadron) with food or milk. What is the physiological basis for this advice?
- A. Inhibits pepsin production
- B. Stimulates hydrochloric acid production
- C. Delays stomach emptying time
- D. Reduces hydrochloric acid production
Correct answer: B
Rationale: The correct answer is B: Stimulates hydrochloric acid production. Dexamethasone can stimulate the production of hydrochloric acid in the stomach, which may lead to irritation of the stomach lining. Taking dexamethasone with food or milk helps to neutralize or buffer the acid, reducing the risk of stomach irritation. Choice A is incorrect because dexamethasone does not inhibit pepsin production. Choice C is incorrect as dexamethasone does not slow stomach emptying time. Choice D is incorrect as dexamethasone does not reduce hydrochloric acid production.
5. When caring for a client receiving warfarin sodium (Coumadin), which lab test would the nurse monitor to determine therapeutic response to the drug?
- A. Bleeding time
- B. Coagulation time
- C. Prothrombin time
- D. Partial thromboplastin time
Correct answer: C
Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.
