HESI LPN
Adult Health 2 Exam 1
1. A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?
- A. Increase intake of green leafy vegetables
- B. Avoid foods high in vitamin K
- C. Increase intake of foods rich in vitamin C
- D. Limit intake of dairy products
Correct answer: B
Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.
2. The nurse plans to administer the rubella vaccine to a postpartum client whose titer is < 1:8 and who is breastfeeding. What information should the nurse provide this client?
- A. The client should bottle feed and pump her breast for 3 days following immunization
- B. The vaccine is given to produce maternal antibodies before lactation occurs
- C. The infant will receive immunization through the mother's breast milk
- D. The client should not get pregnant for 3 months after immunization
Correct answer: D
Rationale: Educating about the waiting period helps prevent possible rubella infection in a subsequent early pregnancy.
3. A client with a severe peanut allergy accidentally ingested peanut-containing food and is experiencing anaphylaxis. What is the nurse's priority action?
- A. Administer an epinephrine injection
- B. Call for immediate medical help
- C. Monitor airway, breathing, and circulation
- D. All of the above
Correct answer: A
Rationale: The priority action for a client experiencing anaphylaxis due to a severe peanut allergy is to administer an epinephrine injection. Epinephrine is the first-line treatment for anaphylaxis as it can rapidly reverse the severe allergic reaction. While calling for immediate medical help is important, administering epinephrine takes precedence because it can be life-saving in this situation. Monitoring airway, breathing, and circulation is essential in managing anaphylaxis, but administering epinephrine is the priority action to halt the progression of the allergic reaction and stabilize the client's condition. Therefore, 'Administer an epinephrine injection' is the most critical initial intervention.
4. A client with a history of pulmonary embolism is on anticoagulant therapy. What should the nurse monitor regularly?
- A. International Normalized Ratio (INR)
- B. Blood glucose levels
- C. Blood pressure
- D. Temperature
Correct answer: A
Rationale: Correct! Monitoring INR is essential in clients on anticoagulant therapy to ensure the blood's clotting time is within the therapeutic range, preventing further embolic events or excessive bleeding. Monitoring blood glucose levels (Choice B), blood pressure (Choice C), and temperature (Choice D) is important for various other conditions but is not directly related to anticoagulant therapy for a client with a history of pulmonary embolism.
5. A client with a diagnosis of rheumatoid arthritis is prescribed methotrexate. What is the primary action of this medication?
- A. Increases joint lubrication
- B. Reduces inflammation by suppressing the immune system
- C. Enhances bone density
- D. Stimulates cartilage regeneration
Correct answer: B
Rationale: The correct answer is B: Methotrexate is an immunosuppressant that works by suppressing the immune system, thereby reducing inflammation in rheumatoid arthritis. Methotrexate does not directly increase joint lubrication (Choice A) as its primary action is on the immune system. Choices C and D are incorrect since methotrexate does not enhance bone density or stimulate cartilage regeneration. It is crucial for healthcare providers to understand the mechanism of action of medications to provide safe and effective care to patients.
