HESI LPN
Adult Health 1 Final Exam
1. The nurse observes that a post-operative client's surgical wound has reddened edges and is oozing. What is the appropriate nursing action?
- A. Apply an antibiotic ointment
- B. Clean the wound with sterile saline
- C. Cover the wound with a sterile dressing
- D. Notify the surgeon immediately
Correct answer: D
Rationale: The correct action when a post-operative client's surgical wound has reddened edges and is oozing is to notify the surgeon immediately. Reddened, oozing wound edges can indicate an infection that requires prompt evaluation and intervention by the surgical team. Applying an antibiotic ointment (Choice A) without proper assessment and guidance can be inappropriate. Cleaning the wound with sterile saline (Choice B) and covering it with a sterile dressing (Choice C) may not address the potential infection adequately, and the client may require more specialized care that the surgeon can provide.
2. The nurse is providing care for a client with a draining postoperative wound infected with methicillin-resistant Staphylococcus aureus (MRSA). Which is the most important action for the nurse to take?
- A. Encourage increased oral fluids.
- B. Provide high-protein snacks.
- C. Change the wound dressing.
- D. Administer prescribed antibiotics.
Correct answer: D
Rationale: Administering prescribed antibiotics is crucial in treating MRSA infections. MRSA is a type of bacteria that is resistant to many antibiotics, including methicillin. Therefore, prompt administration of the appropriate antibiotics is essential to target the MRSA infection effectively. Encouraging increased oral fluids (Choice A) and providing high-protein snacks (Choice B) may be beneficial for overall recovery but are not the most important actions in treating an MRSA infection. Changing the wound dressing (Choice C) is important for wound care but does not directly address the infection caused by MRSA.
3. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?
- A. Filtration
- B. Diffusion
- C. Osmosis
- D. Active transport
Correct answer: C
Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.
4. When inserting an indwelling urinary catheter in a female client and urine flows into the tubing, what is the next action?
- A. Document the color and clarity of the urine
- B. Insert the catheter an additional inch
- C. Ask the client to breathe deeply and slowly exhale
- D. Inflate the balloon with 5 mL of sterile water
Correct answer: D
Rationale: When urine flows into the tubing during the insertion of an indwelling urinary catheter, it confirms proper catheter placement. The next step should be to inflate the balloon with the specified amount of sterile water to secure the catheter in place. Documenting the color and clarity of the urine (choice A) is important for assessment but not the immediate next action. Inserting the catheter further (choice B) without securing it could cause harm. Asking the client to breathe deeply (choice C) is not relevant to this situation.
5. A client is diagnosed with type 1 diabetes mellitus. Which instruction about insulin administration should the nurse emphasize?
- A. Rotate injection sites to prevent tissue damage
- B. Inject insulin into the same site to increase absorption
- C. Only use insulin pens
- D. Mix different types of insulin in the same syringe
Correct answer: C
Rationale: The correct answer is to only use insulin pens. This is because insulin pens provide a convenient and accurate way to administer insulin. Rotating injection sites is important to prevent tissue damage and promote consistent insulin absorption, making choice A incorrect. Injecting insulin into the same site can lead to lipodystrophy and is not recommended, making choice B incorrect. Mixing different types of insulin in the same syringe can alter their action profiles and is generally not recommended, making choice D incorrect.
