HESI LPN
HESI Fundamentals Exam
1. The healthcare provider is preparing a client with deep vein thrombosis (DVT) for a Venous Doppler evaluation. Which of the following would be necessary for preparing the client for this test?
- A. Client should be NPO prior to the test
- B. Client should receive a sedative medication before the test
- C. Discontinue anticoagulant therapy before the test
- D. No special preparation is necessary
Correct answer: D
Rationale: No special preparation is required for a Venous Doppler evaluation. Option A is incorrect because there is no need for the client to be NPO (nothing by mouth) before this test. Option B is incorrect as sedative medication is not typically administered for a Venous Doppler evaluation. Option C is incorrect as discontinuing anticoagulant therapy before the test may not be safe for a client with DVT, as it could increase the risk of developing a blood clot. Therefore, the correct answer is D.
2. The nurse is planning care for a patient with acute hypernatremia. What should the nurse include in this patient's plan of care? (select one that does not apply)
- A. Reduce IV access
- B. Limit length of visits
- C. Restrict fluids to 1500 mL per day
- D. Conduct frequent neurologic checks
Correct answer: D
Rationale: For a patient with acute hypernatremia, the nurse should include interventions like reducing free water losses, correcting sodium levels slowly, monitoring neurologic status, and ensuring adequate fluid intake. Conducting frequent neurologic checks is essential in assessing the patient's neurological status and detecting any changes promptly. Therefore, this action should not be excluded from the plan of care. Choices A, B, and C are not directly related to managing acute hypernatremia and can be safely excluded from the plan of care. Reducing IV access, limiting length of visits, and restricting fluids to 1500 mL per day are not appropriate actions for managing acute hypernatremia.
3. The healthcare provider notes that a client has a new prescription for 20 mEq of potassium. The IV site is inflamed but not tender, and has a blood flashback. What action should the healthcare provider take?
- A. Obtain a liter of normal saline with 20 mEq of KCl
- B. Contact the healthcare provider to clarify the prescription
- C. Withhold the prescription medication until a new IV is started
- D. Fax the prescription to the pharmacy for immediate dispensing
Correct answer: B
Rationale: The healthcare provider should contact the prescriber to clarify the prescription because an inflamed IV site may indicate potential issues with administering the medication. It is important to ensure that the prescription is appropriate and safe for the client before proceeding with administration. Option A is incorrect because administering potassium through an inflamed IV site can lead to further complications. Option C is not the best course of action as clarifying the prescription first is essential. Option D is also incorrect as the focus should be on ensuring the safety of the client before dispensing the medication.
4. The client with chronic obstructive pulmonary disease (COPD) is being educated about lifestyle changes. Which statement by the client indicates a need for further teaching?
- A. I will reduce my salt intake.
- B. I will exercise for 30 minutes most days of the week.
- C. I will drink alcohol only on the weekends.
- D. I will monitor my blood pressure regularly.
Correct answer: C
Rationale: The correct answer is C. Clients with COPD should limit alcohol intake, not just to weekends, to effectively manage their condition. Excessive alcohol consumption can worsen respiratory symptoms and interfere with medications. Choices A, B, and D are all appropriate and beneficial for clients with COPD. Salt intake reduction helps in managing fluid retention and blood pressure. Regular exercise improves lung function and overall health. Monitoring blood pressure is crucial for individuals with COPD as hypertension is a common comorbidity.
5. A client with obsessive-compulsive disorder (OCD) spends several hours a day washing his hands. What is the most therapeutic nursing intervention?
- A. Allow the client to continue the behavior to reduce anxiety.
- B. Schedule specific times for handwashing.
- C. Encourage the client to discuss the thoughts and feelings behind the behavior.
- D. Restrict the client's access to soap and water.
Correct answer: C
Rationale: Encouraging the client to discuss the thoughts and feelings behind the behavior is the most therapeutic nursing intervention for a client with OCD who excessively washes hands. This approach can help the client understand the underlying reasons for the behavior, address the associated anxiety, and work toward behavior modification. Choices A, allowing the behavior to continue, and D, restricting access to soap and water, do not address the root cause of the behavior and may exacerbate anxiety. Choice B, scheduling specific times for handwashing, does not address the underlying emotional factors contributing to the behavior and may not effectively reduce the client's anxiety.
