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 has a prescription for a Transcutaneous Electrical Nerve Stimulator (TENS) unit for pain management during the postoperative period following a Lumbar Laminectomy. What information should the nurse reinforce about the action of this adjuvant pain modality?
- A. Mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
- B. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
- C. An infusion of medication in the spinal canal will block pain perception
- D. The discharge of electricity will distract the client's focus on the pain
Correct answer: A
Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.
3. The nurse is assessing a client with chronic liver disease. Which lab value is most concerning?
- A. Elevated AST and ALT levels
- B. Decreased albumin level
- C. Elevated bilirubin level
- D. Prolonged PT/INR
Correct answer: D
Rationale: In a client with chronic liver disease, a prolonged PT/INR is the most concerning lab value. This finding indicates impaired liver function affecting the synthesis of clotting factors, leading to an increased risk of bleeding. Elevated AST and ALT levels (Choice A) indicate liver cell damage but do not directly correlate with the risk of bleeding. A decreased albumin level (Choice B) is common in liver disease but is not the most concerning in terms of bleeding risk. Elevated bilirubin levels (Choice C) are seen in liver disease but do not directly reflect the risk of bleeding as PT/INR values do.
4. A client with a history of atrial fibrillation is prescribed warfarin. Which lab value should the nurse monitor to assess the effectiveness of this medication?
- A. Hemoglobin
- B. White blood cell count
- C. Platelet count
- D. INR
Correct answer: D
Rationale: The correct answer is D, INR (International Normalized Ratio). The INR is used to monitor the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication commonly prescribed for conditions like atrial fibrillation. Monitoring the INR helps healthcare providers ensure that the blood is clotting within a therapeutic range. Hemoglobin (Choice A), white blood cell count (Choice B), and platelet count (Choice C) are not directly related to monitoring the effectiveness of warfarin therapy in this context.
5. How should the nurse assess for cyanosis in a client with dark skin who is in respiratory distress?
- A. Abnormal skin color changes in a client with dark skin cannot be determined
- B. Blanching the soles of the feet in a client with dark skin reveals cyanosis
- C. The lips and mucus membranes of a client with dark skin are dusky in color
- D. Cyanosis in a client with dark skin is seen in the sclera
Correct answer: C
Rationale: Observing the lips and mucous membranes provides a reliable indicator of cyanosis in clients with dark skin tones. Choice A is incorrect because cyanosis can be assessed in clients with dark skin by observing other body areas. Choice B is incorrect as blanching the soles of the feet is not a relevant method for assessing cyanosis. Choice D is incorrect as cyanosis is not typically seen in the sclera in clients with dark skin.
