A nurse is providing care to a 17-year-old client in the post-operative care unit (PACU) after an emergency appendectomy. Which finding is an early indication that the client is experiencing poor oxygenation?
- A. Abnormal breath sounds
- B. Cyanosis of the lips
- C. Increasing pulse rate
- D. Pulse oximeter reading of 92%
Correct Answer: C
Rationale: An increasing pulse rate can be an early sign of poor oxygenation as the body tries to compensate. Abnormal breath sounds (choice A) can indicate respiratory issues, but they may not always be an early sign of poor oxygenation. Cyanosis of the lips (choice B) is a late sign of inadequate oxygenation. A pulse oximeter reading of 92% (choice D) indicates mild hypoxemia but may not be considered an early indication of poor oxygenation.

What is the most suitable snack food for the LPN/LVN to offer a client with myasthenia gravis who is at risk for altered nutritional status?
- A. Chocolate pudding.
- B. Graham crackers.
- C. Sugar-free gelatin.
- D. Apple slices.
Correct Answer: A
Rationale: Chocolate pudding is the best snack food choice for a client with myasthenia gravis at risk for altered nutritional status due to its nutrient density and soft texture, which can be easier for clients with swallowing difficulties to consume. Graham crackers, sugar-free gelatin, and apple slices may not provide the same level of nutrient density or ease of consumption for these clients. Graham crackers and apple slices may also pose challenges for clients with swallowing difficulties, while sugar-free gelatin, although a good option for some clients, may not offer the same level of nutrition as chocolate pudding.
What is the first step a healthcare professional should take when preparing to provide tracheostomy care?
- A. Perform hand hygiene
- B. Gather equipment
- C. Explain the procedure
- D. Assess the client
Correct Answer: A
Rationale: Performing hand hygiene is the initial step a healthcare professional should take when preparing to provide tracheostomy care. This step is crucial to prevent the transmission of pathogens and reduce the risk of infection to the client. By cleansing the hands, the healthcare professional ensures patient safety. While gathering equipment, explaining the procedure, and assessing the client are essential components of tracheostomy care, they should occur after performing hand hygiene to maintain aseptic technique and minimize the risk of introducing harmful microorganisms to the client.
A client with diabetes mellitus is being taught by a nurse how to perform a capillary blood glucose test. Which of the following instructions should the nurse include in the teaching?
- A. Don sterile gloves after cleansing the site
- B. Puncture the site after cleansing and before the antiseptic dries
- C. Gently wipe the puncture site until a large droplet of blood forms
- D. Hold the finger below the heart level to puncture
Correct Answer: B
Rationale: The correct instruction is to puncture the site after cleansing and before the antiseptic dries. This sequence helps ensure proper blood collection without introducing contaminants. Choice A is incorrect because wearing sterile gloves is not necessary for capillary blood glucose testing. Choice C is incorrect as wiping the puncture site can introduce contaminants and alter the blood sample. Choice D is incorrect as holding the finger below the heart level is not required for a capillary blood glucose test.
The nurse is providing care for a client who is receiving total parenteral nutrition (TPN). Which laboratory value should the nurse monitor closely to assess for complications?
- A. Serum potassium
- B. Blood glucose
- C. Serum sodium
- D. Serum calcium
Correct Answer: B
Rationale: The correct answer is B: Blood glucose. When caring for a client receiving total parenteral nutrition (TPN), monitoring blood glucose levels is essential due to the increased risk of hyperglycemia associated with TPN infusion. Elevated blood glucose levels can lead to complications such as hyperglycemia, which can be harmful to the client. While monitoring serum potassium (Choice A), serum sodium (Choice C), and serum calcium (Choice D) are also important aspects of care, when specifically considering TPN administration, blood glucose monitoring takes precedence due to the potential for significant complications related to glucose imbalances.
The client has expressive aphasia and needs assistance to communicate. Which method should the LPN use to best support the client's ability to express basic needs?
- A. Use a picture board with common needs.
- B. Encourage the client to speak slowly.
- C. Write down what the client says.
- D. Use hand gestures to communicate.
Correct Answer: A
Rationale: The correct answer is to use a picture board with common needs. Clients with expressive aphasia have difficulty speaking but can often understand and use visual aids effectively. Using a picture board helps the client communicate basic needs more easily. Encouraging the client to speak slowly (choice B) may not be effective as the issue lies with expressive language, not speed. Writing down what the client says (choice C) may not always be possible or helpful for immediate communication as it does not address the communication barrier directly. Using hand gestures (choice D) may not be as clear or universally understood as a picture board, which can cause confusion and misinterpretation.
