HESI LPN
Adult Health 2 Exam 1
1. The nurse is monitoring a client's intravenous infusion and observes that the venipuncture site is cool to the touch, swollen, and the infusion rate is slower than the prescribed rate. What is the most likely cause of this finding?
- A. The solution's rate is too rapid
- B. The client has phlebitis
- C. The infusion site is infected
- D. The infusion is infiltrated
Correct answer: D
Rationale: The correct answer is D. An infiltrated IV occurs when fluid leaks into the surrounding tissue, causing coolness, swelling, and a slow infusion rate. Choice A is incorrect because a rapid solution rate does not typically cause these specific symptoms. Choice B, phlebitis, presents with redness, warmth, and tenderness along the vein, not coolness. Choice C, infection, usually manifests with redness, warmth, and possibly purulent drainage, not coolness and swelling.
2. A client is scheduled for an abdominal ultrasound in the morning and has been instructed to fast overnight. The client asks the nurse why fasting is necessary. What is the best response?
- A. It helps reduce the production of intestinal gases.
- B. It ensures clearer imaging by emptying the stomach.
- C. It prevents the risk of aspiration during the procedure.
- D. It is a standard procedure for all surgical interventions.
Correct answer: B
Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.
3. A client with a history of congestive heart failure is prescribed digoxin (Lanoxin). Which assessment is most important for the nurse to obtain before administering this medication?
- A. Blood pressure
- B. Heart rate
- C. Respiratory rate
- D. Oxygen saturation
Correct answer: B
Rationale: The correct answer is B: Heart rate. Before administering digoxin to a client with a history of congestive heart failure, the nurse must assess the client's heart rate. Digoxin can cause bradycardia, so monitoring the heart rate is crucial to prevent potential complications. Assessing blood pressure, respiratory rate, and oxygen saturation are important assessments but are not as directly influenced by digoxin as heart rate is in this scenario. Blood pressure can be affected by various factors, including dehydration or other medications. Respiratory rate and oxygen saturation are more related to respiratory function and gas exchange, which are not the primary concerns when administering digoxin to a client with heart failure.
4. A client who has just been diagnosed with tuberculosis (TB) is being discharged home. Which instruction is most important for the nurse to provide?
- A. Avoid close contact with others until treatment is complete
- B. Take all prescribed medications as directed
- C. Schedule a follow-up appointment with the healthcare provider
- D. Wear a mask when in public places
Correct answer: B
Rationale: The correct answer is B: 'Take all prescribed medications as directed.' This instruction is the most important because adherence to the prescribed medication regimen is crucial in treating tuberculosis effectively and preventing the development of drug-resistant TB. While choice A is important for infection control, ensuring treatment adherence through proper medication intake takes precedence. Choice C is also essential for monitoring progress but is not as critical as ensuring medication compliance. Choice D is relevant for preventing transmission but is not as crucial as ensuring proper treatment by taking medications as directed.
5. While caring for a client's postoperative dressing, the nurse observes purulent wound drainage. Previously, the wound was inflamed and tender but without drainage. Which is the most important action for the nurse to take?
- A. Determine if the drainage has an unpleasant odor.
- B. Monitor the client's white blood cell count (WBC).
- C. Request a culture and sensitivity of the wound.
- D. Cleanse the wound with a sterile saline solution.
Correct answer: C
Rationale: Requesting a culture and sensitivity of the wound is the most crucial action in this scenario. This will help identify the specific organism causing the infection and determine its sensitivity to antibiotics, guiding appropriate antibiotic therapy. Option A is less critical as odor alone may not provide enough information about the type of infection. Monitoring the client's white blood cell count (WBC) in option B is important but not as immediate as obtaining a wound culture. Cleansing the wound with a sterile saline solution in option D is necessary but should follow after obtaining the culture results to ensure proper treatment.
