HESI LPN
Adult Health 2 Final Exam
1. The healthcare provider is preparing to administer a 1.2mL injection to a 4-year-old. Which is the best site to administer an IM injection?
- A. Vastus Lateralis
- B. Radial artery
- C. Dorsogluteal
- D. Rectus femoris
Correct answer: A
Rationale: The correct answer is A, Vastus Lateralis. The vastus lateralis site is recommended for IM injections in small children due to its large muscle mass, making it suitable for injections in pediatric patients. Choices B, C, and D are incorrect. The radial artery is not a site for IM injections; it is a site for arterial puncture. The dorsogluteal site is not recommended for children due to potential risks, such as injury to the sciatic nerve. The rectus femoris is not typically used for IM injections in children, as other sites like the vastus lateralis are more commonly preferred.
2. A client is to have mafenide (Sulfamylon) cream applied to burned areas. For which serious side effect of mafenide therapy should the LPN/LVN monitor this client?
- A. Curling ulcer
- B. Renal shutdown
- C. Metabolic acidosis
- D. Hemolysis of red blood cells
Correct answer: C
Rationale: Corrected Rationale: Metabolic acidosis is a serious side effect of mafenide therapy that should be closely monitored. Mafenide can lead to metabolic acidosis due to its inhibition of carbonic anhydrase, resulting in the accumulation of carbonic acid. Curling ulcer (Choice A) is a stress-related mucosal lesion that occurs in the duodenum, primarily due to severe burns, not directly related to mafenide therapy. Renal shutdown (Choice B) is not a common side effect of mafenide therapy. Hemolysis of red blood cells (Choice D) is not a recognized side effect of mafenide cream application.
3. The nurse determines that a client with cirrhosis is experiencing peripheral neuropathy. What action should the nurse take?
- A. Protect the client's feet from injury
- B. Apply a heating pad to affected area
- C. Keep the client's feet elevated
- D. Assess the feet and legs for jaundice
Correct answer: A
Rationale: Protecting the client's feet from injury is essential when managing peripheral neuropathy in a client with cirrhosis. Peripheral neuropathy can result in reduced sensation, increasing the risk of injury. Applying a heating pad or keeping the client's feet elevated would not address the primary concern of preventing injury. Assessing the feet and legs for jaundice is important for monitoring liver function, but it is not directly related to managing peripheral neuropathy in this case.
4. The nurse is caring for a client who is receiving 24-hour total parenteral nutrition (TPN) via a central line at 54 ml/hr. When initially assessing the client, the nurse notes that the TPN solution has run out and the next TPN solution is not available. What immediate action should the nurse take?
- A. Infuse normal saline at a keep-vein-open rate.
- B. Discontinue the IV and flush the port with heparin.
- C. Infuse 10% dextrose and water at 54 ml/hr.
- D. Obtain a stat blood glucose level and notify the healthcare provider.
Correct answer: C
Rationale: Infusing 10% dextrose and water at 54 ml/hr is the correct action to prevent hypoglycemia until the next TPN solution becomes available. This solution will help maintain the client's glucose levels. Infusing normal saline at a keep-vein-open rate (Choice A) is not appropriate for maintaining glucose levels and would not address the nutritional needs provided by TPN. Discontinuing the IV and flushing the port with heparin (Choice B) is unnecessary and not indicated in this situation as the client still needs fluid and nutrition. Obtaining a stat blood glucose level and notifying the healthcare provider (Choice D) can be done later but is not the immediate action required when the TPN solution has run out.
5. During a manic episode, what is the most appropriate intervention to implement first for a client with bipolar disorder?
- A. Engage the client in a quiet activity
- B. Provide a structured environment with minimal stimulation
- C. Monitor the client continuously
- D. Adjust the lighting and noise levels
Correct answer: B
Rationale: During a manic episode, individuals with bipolar disorder may experience sensory overload and agitation. Providing a structured environment with minimal stimulation is the most appropriate initial intervention as it can help reduce overwhelming sensory input and promote a sense of calm. Engaging the client in a quiet activity (Choice A) may not be effective if the environment is still overstimulating. Continuous monitoring (Choice C) is important but may not be the first intervention needed. Adjusting lighting and noise levels (Choice D) can be helpful but may not address the core issue of sensory overload and agitation during a manic episode.
