HESI RN
HESI Fundamentals
1. A client is scheduled for a colonoscopy. What instruction should the nurse provide to prepare the client for the procedure?
- A. Drink clear liquids for 24 hours before the procedure
- B. Take a laxative the morning of the procedure
- C. Eat a light meal before the procedure
- D. Avoid drinking fluids for 4 hours before the procedure
Correct answer: A
Rationale: The correct instruction for preparing a client for a colonoscopy is to drink clear liquids for 24 hours before the procedure. This step helps to ensure the bowel is adequately cleared for the colonoscopy, allowing for better visualization and examination of the colon.
2. The nurse is caring for a newly admitted patient who has severe gastroenteritis. The patient’s electrolytes reveal a serum sodium level of 140 mEq/L and a serum potassium level of 3.5 mEq/L. The nurse receives an order for intravenous 5% dextrose and normal saline with 20 mEq/L potassium chloride to infuse at 125 mL per hour. Which action is necessary prior to administering this fluid?
- A. Evaluate the patient’s urine output.
- B. Contact the provider to order arterial blood gases.
- C. Request an order for an initial potassium bolus.
- D. Suggest a diet low in sodium and potassium.
Correct answer: A
Rationale: Prior to administering IV fluids containing potassium, it is crucial to evaluate the patient's urine output. If the urine output is less than 25 mL/hr or 600 mL/day, there is a risk of potassium accumulation. Patients with low urine output should not receive IV potassium to prevent potential complications. Contacting the provider for arterial blood gases is unnecessary in this scenario as it does not directly relate to the administration of IV fluids with potassium. Administering potassium as a bolus is not recommended due to potential adverse effects. While dietary considerations are important, suggesting a low-sodium and low-potassium diet is not the immediate action required before administering IV fluids with potassium chloride.
3. When evaluating the effectiveness of a client’s nursing care, the nurse first reviews the expected outcomes identified in the plan of care. What action should the nurse take next?
- A. Determine if the expected outcomes were realistic
- B. Obtain current client data to compare with expected outcomes
- C. Modify the nursing interventions to achieve the client’s goals
- D. Review related professional standards of care
Correct answer: A
Rationale: After reviewing the expected outcomes identified in the plan of care, the nurse's next step should be to determine if these outcomes were realistic. This assessment helps in understanding if the goals set were achievable and appropriate for the client's condition before proceeding to compare them with current client data or modifying nursing interventions. By verifying the realism of the expected outcomes, the nurse ensures a solid foundation for further evaluation and adjustment of the care plan. Option B is incorrect because obtaining current client data comes after assessing the realism of the expected outcomes. Option C is incorrect because modifying nursing interventions should be based on the assessment of the expected outcomes' realism. Option D is incorrect as reviewing professional standards of care is important but not the immediate next step after assessing the expected outcomes' realism.
4. A client is admitted with a diagnosis of chronic obstructive pulmonary disease (COPD) exacerbation. Which intervention should the nurse implement first?
- A. Administer bronchodilators as prescribed.
- B. Administer oxygen via nasal cannula.
- C. Encourage the client to cough and deep breathe.
- D. Position the client in high Fowler's position.
Correct answer: B
Rationale: Administering oxygen via nasal cannula (B) is the priority intervention for a client with COPD exacerbation to improve oxygenation. In COPD exacerbation, there is impaired gas exchange leading to hypoxemia, making oxygen therapy the initial priority. Administering bronchodilators (A) helps with bronchodilation but should come after ensuring adequate oxygenation. Encouraging coughing and deep breathing (C) and positioning the client in high Fowler's position (D) are also beneficial interventions, but the first step is to address the oxygenation needs of the client.
5. The healthcare provider explains through an interpreter the risks and benefits of a scheduled surgical procedure to a non-English speaking female client. The client gives verbal consent, and the healthcare provider leaves, instructing the nurse to witness the signature on the consent form. The client and the interpreter then speak together in the foreign language for an additional 2 minutes until the interpreter concludes, 'She says it is OK.' What action should the nurse take next?
- A. Ask for a full explanation from the interpreter of the witnessed discussion.
- B. Have the client sign the consent form.
- C. Document the conversation and witness the consent.
- D. Ask the client directly if she has any questions.
Correct answer: A
Rationale: The correct action for the nurse to take next is to ask for a full explanation from the interpreter of the witnessed discussion. Verbal consent is not sufficient; it is crucial to ensure that the client fully comprehends the risks and benefits of the surgical procedure. By asking the interpreter to provide a detailed explanation of the discussion, the nurse can confirm that the client has given informed consent. Having the client sign the consent form (Choice B) without ensuring complete understanding may lead to potential misunderstandings. Documenting the conversation and witnessing the consent (Choice C) is not enough to guarantee the client's comprehension. Asking the client directly if she has any questions (Choice D) may not be effective if language barriers persist.
