1. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?
- A. Serum potassium
- B. Serum calcium
- C. Serum albumin
- D. Serum sodium
Correct answer: C
Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.
2. A healthcare provider is providing discharge teaching to a client about self-administering heparin.
- A. Administer medication in the abdomen.
- B. Administer medication in the thigh.
- C. Administer medication in the upper arm.
- D. Administer medication in the buttock.
Correct answer: A
Rationale: Heparin is typically administered in the abdomen for self-injection to avoid muscle tissue and for better absorption. The subcutaneous tissue in the abdomen provides a larger area for injection and is usually recommended for heparin administration. Administering heparin in the thigh, upper arm, or buttock may not be as effective or safe as the abdomen due to variations in absorption rates and potential risks associated with muscle injection.
3. A client is receiving discharge instructions for using a walker. Which statement indicates an understanding of the teaching?
- A. I will hire someone to trim the tree that hangs low over the stairs of my front porch.
- B. I will avoid using the walker on uneven surfaces.
- C. I will use the walker on stairs for added support.
- D. I will not need to make any changes to my home environment.
Correct answer: A
Rationale: The correct answer is A because hiring someone to trim low-hanging branches over stairs ensures home safety and reflects an understanding of walker use. This action indicates the client's awareness of potential hazards and the importance of a safe environment for walker use. Choice B is incorrect as avoiding uneven surfaces is a general safety precaution but does not directly relate to walker use and does not demonstrate an understanding of the teaching. Choice C is incorrect because using a walker on stairs is not recommended due to safety concerns such as balance and fall risks. Choice D is incorrect as making no changes to the home environment may pose safety risks when using a walker, showing a lack of understanding regarding safety precautions needed for walker use.
4. A client is prescribed a buccal medication. Which of the following client statements indicates that the client understands how to take this medication?
- A. “I will first dissolve the tablet in water.”
- B. “I will insert the tablet between my cheek and teeth.”
- C. “I will place the tablet under my tongue.”
- D. “I will chew the tablet.”
Correct answer: B
Rationale: The correct way to take buccal medications is to insert the tablet between the cheek and gums where it will dissolve slowly. Option A is incorrect because buccal medications are not meant to be dissolved in water. Option C is incorrect as sublingual medications are placed under the tongue. Option D is incorrect because chewing a buccal tablet is not the correct administration method.
5. A nurse is preparing to insert an IV catheter for an adult client. Which of the following actions should the nurse take?
- A. Choose the most distal site on the selected extremity
- B. Apply a cool compress to the selected extremity before insertion of the IV catheter
- C. Stroke the selected extremity before insertion of the IV catheter
- D. Place the tourniquet above the proposed insertion site
Correct answer: C
Rationale: When preparing to insert an IV catheter, stroking the extremity before insertion helps to visualize veins, making it easier to locate a suitable vein for catheter insertion. Choosing the most distal site on the extremity is correct because veins more distal are preferred for IV catheter insertion. Applying a cool compress to the extremity before insertion is unnecessary and not a standard practice. Placing the tourniquet below the proposed insertion site is incorrect; the tourniquet should be placed above the proposed insertion site to help engorge the veins for easier visualization and access.
