HESI Fundamentals Practice Exam
1. The healthcare professional is administering an intermittent infusion of an antibiotic to a client with an antecubital saline lock. After opening the roller clamp on the IV tubing, the alarm on the infusion pump indicates an obstruction. What action should be taken first?
- A. Check for a blood return.
- B. Reposition the client's arm.
- C. Remove the IV site dressing.
- D. Flush the lock with saline.
Correct answer: B
Rationale: Repositioning the client's arm is the initial action to take when encountering an obstruction with an antecubital saline lock. Repositioning may correct any bending at the elbow that could be causing the obstruction, allowing for smoother infusion flow. Checking for a blood return, removing the IV site dressing, or flushing the lock with saline would be subsequent actions once the obstruction is addressed. Checking for a blood return is done to confirm proper placement, removing the IV site dressing is necessary for site assessment, and flushing the lock with saline helps maintain patency but should not be the first action when an obstruction is detected.
2. The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?
- A. To promote oxygenation by removing secretions.
- B. To reduce the amount of air trapped in the lungs.
- C. To increase the amount of carbon dioxide exhaled.
- D. To slow the respiratory rate and improve air exchange.
Correct answer: C
Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A) and reducing air trapping (B) can be associated benefits to some extent, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics. Slowing the respiratory rate (D) is not the primary purpose of pursed-lip breathing.
3. During the assessment, a client receiving a continuous infusion of heparin for deep vein thrombosis (DVT) is found to have a nosebleed. Which finding requires immediate action?
- A. The client's activated partial thromboplastin time (aPTT) is 70 seconds.
- B. The client has developed a nosebleed.
- C. The client's blood pressure is 150/90 mm Hg.
- D. The client reports feeling lightheaded.
Correct answer: B
Rationale: A nosebleed (B) in a client receiving heparin is a sign of heparin toxicity and requires immediate action. It indicates that the client is at risk of excessive bleeding. While a prolonged aPTT of 70 seconds (A) is worth monitoring, active bleeding takes precedence. Elevated blood pressure (C) and lightheadedness (D) are potential side effects of heparin but are not as urgently concerning as active bleeding.
4. The nurse is providing discharge teaching to a client with a new prescription for warfarin (Coumadin). Which dietary instruction should the nurse include?
- A. Avoid foods high in vitamin K
- B. Increase intake of leafy green vegetables
- C. Consume a consistent amount of foods high in potassium
- D. Limit intake of high-protein foods
Correct answer: A
Rationale: The correct dietary instruction for a client taking warfarin is to avoid foods high in vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consuming foods high in vitamin K, such as leafy green vegetables, can antagonize the effects of warfarin, potentially leading to treatment inefficacy or fluctuations in anticoagulation levels. Therefore, clients on warfarin therapy should be advised to avoid foods high in vitamin K to maintain the effectiveness of the medication. Choices B, C, and D are incorrect because increasing leafy green vegetables (choice B) would introduce more vitamin K, consuming a consistent amount of foods high in potassium (choice C) is not directly related to warfarin therapy, and limiting high-protein foods (choice D) is not a specific concern for clients on warfarin therapy.
5. The client is reviewing the signed operative consent with a nurse, who is admitted for the removal of a lipoma on the left leg. The client states that the consent form should say the removal of a lipoma on the right leg. Which intervention should the nurse implement?
- A. Notify the surgical team of the client’s confusion
- B. Have the client sign a new surgical consent
- C. Add the correct leg information to the consent form
- D. Inform the surgeon about the client’s concern
Correct answer: D
Rationale: In this scenario, the nurse should inform the surgeon about the client’s concern immediately. This is important to ensure that the correct procedure is performed on the intended leg. Communication with the surgeon is crucial to address any discrepancies in the consent form and prevent errors during the surgical procedure. Having the surgeon clarify and correct the consent form is essential to maintain patient safety and uphold the principles of informed consent.
