HESI LPN
Adult Health 2 Exam 1
1. The nurse is caring for a client who underwent a total knee replacement yesterday. What activity level should the nurse encourage today?
- A. Bed rest with bathroom privileges only
- B. Frequent, short walks with assistance
- C. Range of motion exercises to the knee every four hours
- D. Leg elevation to reduce swelling
Correct answer: B
Rationale: After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.
2. If an individual receives a recessive gene for eye color from both parents, the:
- A. gender of the child will not determine the expression of that trait.
- B. recessive trait will be expressed in the child.
- C. recessive trait will be expressed in all the offspring.
- D. recessive trait will be suppressed, and the dominant trait will not be expressed.
Correct answer: B
Rationale: When an individual inherits a recessive gene for eye color from both parents, the recessive trait will be expressed in the child. This is because having two copies of the recessive gene overrides the presence of any dominant gene. Choice A is incorrect because the expression of the trait is determined by the genetic makeup, not the gender of the child. Choice C is incorrect as the expression of the recessive trait is certain when both parents pass on the recessive gene, but it does not mean that all offspring will express the trait. Choice D is incorrect because if both parents provide a recessive gene, the dominant trait will not be expressed in the child, but it does not mean it will be suppressed; rather, the recessive trait will be expressed.
3. The nurse notes that a depressed female client has been more withdrawn and non-communicative during the past two weeks. Which intervention is most important to include in the updated plan of care for this client?
- A. Encourage the client's family to visit more often
- B. Schedule a daily conference with the social worker
- C. Encourage the client to participate in group activities
- D. Engage the client in a non-threatening conversation
Correct answer: D
Rationale: Engaging the client in a non-threatening conversation is crucial as it can help build trust and provide support, addressing the client's withdrawal. This intervention focuses on establishing a therapeutic relationship and giving the client an opportunity to express their feelings. Choices A, B, and C do not directly target the client's need for communication and may not address the underlying issues contributing to her withdrawal. Encouraging the client's family to visit more often (Choice A) may add pressure or discomfort to the client. Scheduling a daily conference with the social worker (Choice B) may not address the client's immediate need for communication. Encouraging the client to participate in group activities (Choice C) may be overwhelming for the client and not address her withdrawal directly.
4. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). The nurse should monitor the client for which of the following laboratory values?
- A. Prothrombin time (PT)
- B. Serum potassium
- C. Blood urea nitrogen (BUN)
- D. White blood cell count (WBC)
Correct answer: A
Rationale: The correct answer is A: Prothrombin time (PT). Prothrombin time is monitored to assess the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors, including factors II, VII, IX, and X. Monitoring the PT helps ensure that the client's blood is clotting within the desired therapeutic range to prevent complications such as recurrent DVT or excessive bleeding. Choices B, C, and D are incorrect because serum potassium, blood urea nitrogen, and white blood cell count are not directly related to monitoring warfarin therapy in a client with a history of DVT.
5. When performing nasotracheal suctioning on a client with a respiratory infection, what technique should be used?
- A. Apply intermittent suction when withdrawing the catheter.
- B. Apply continuous suction during insertion of the catheter.
- C. Apply suction only during insertion of the catheter.
- D. Insert the catheter while the client is exhaling.
Correct answer: A
Rationale: The correct technique for nasotracheal suctioning is to apply intermittent suction when withdrawing the catheter. This method helps prevent damage to the mucosa and is the recommended approach. Continuous suction during insertion (choice B) can cause trauma to the airway lining. Applying suction only during insertion (choice C) is not sufficient for effective removal of secretions. Inserting the catheter while the client is exhaling (choice D) does not follow the standard procedure for nasotracheal suctioning.
