HESI LPN
Adult Health 2 Final Exam
1. A client with a diagnosis of osteoporosis is prescribed alendronate (Fosamax). What is the most important instruction the nurse should provide?
- A. Take the medication in the morning on an empty stomach.
- B. Take the medication at bedtime.
- C. Remain upright for at least 30 minutes after taking the medication.
- D. Take the medication with a full glass of water.
Correct answer: D
Rationale: The most important instruction the nurse should provide to a client prescribed alendronate (Fosamax) for osteoporosis is to take the medication with a full glass of water. This is crucial to help prevent esophageal irritation. Option A is correct as alendronate should be taken in the morning on an empty stomach. Option C is incorrect because the client should remain upright for at least 30 minutes after taking the medication, not lie down. Option B is incorrect and a duplicate of Option A.
2. Which type of cell is responsible for producing antibodies in the immune system?
- A. B lymphocytes
- B. T lymphocytes
- C. Macrophages
- D. Neutrophils
Correct answer: A
Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.
3. The nurse is providing care for a client with a wound infection. Which type of precautions should the nurse implement?
- A. Airborne precautions
- B. Droplet precautions
- C. Contact precautions
- D. Standard precautions
Correct answer: C
Rationale: Contact precautions are necessary when caring for a client with a wound infection to prevent the spread of infection. Contact precautions involve practices such as wearing gloves and gowns, and ensuring proper hand hygiene. Airborne precautions are for diseases transmitted by small droplet nuclei that can remain suspended in the air, like tuberculosis. Droplet precautions are for diseases transmitted through respiratory droplets larger than 5 microns, such as influenza. Standard precautions are used for all clients to prevent the spread of infection and include practices like hand hygiene, use of personal protective equipment, and safe injection practices. In this case, since the client has a wound infection, the nurse should focus on implementing contact precautions to reduce the risk of spreading the infection to themselves or others.
4. A client with type 1 diabetes mellitus is experiencing hypoglycemia. What is the best initial action for the LPN/LVN to take?
- A. Administer glucagon intramuscularly.
- B. Give the client 4 ounces of orange juice.
- C. Give the client a snack containing protein and carbohydrates.
- D. Encourage the client to rest until symptoms resolve.
Correct answer: B
Rationale: The best initial action for a client with type 1 diabetes mellitus experiencing hypoglycemia is to give them 4 ounces of orange juice. Orange juice quickly raises blood glucose levels in a hypoglycemic client. Administering glucagon intramuscularly is not the best initial action for hypoglycemia; it is usually reserved for severe hypoglycemia cases. Giving a snack containing protein and carbohydrates is not as rapid as orange juice in raising blood glucose levels during hypoglycemia. Encouraging the client to rest until symptoms resolve does not address the immediate need to raise blood glucose levels in a hypoglycemic state.
5. When caring for a client receiving warfarin sodium (Coumadin), which lab test would the nurse monitor to determine therapeutic response to the drug?
- A. Bleeding time
- B. Coagulation time
- C. Prothrombin time
- D. Partial thromboplastin time
Correct answer: C
Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.
