Nursing Elites

1. A client is postoperative following hip replacement surgery. Which of the following instructions should the nurse include in preventing dislocation of the prosthesis?

• A. Cross your legs at the knees
• B. Avoid bending your hip more than 90 degrees
• C. Sit with your legs elevated
• D. Avoid placing a pillow under your knees

Correct answer: B

Rationale: To prevent dislocation of the prosthesis after hip replacement surgery, it is essential to avoid bending the hip more than 90 degrees. This precaution helps maintain the stability of the hip joint and reduces the risk of prosthesis dislocation. Crossing legs at the knees (Choice A) can increase pressure on the hip joint, leading to instability. Sitting with legs elevated (Choice C) and avoiding placing a pillow under the knees (Choice D) do not directly address the risk of prosthesis dislocation.

2. What are the primary differences between Type 1 and Type 2 diabetes in terms of pathophysiology and treatment?

• A. Type 1: No insulin production; Type 2: Insulin resistance
• B. Type 1: Insulin resistance; Type 2: Insulin deficiency
• C. Type 1: Autoimmune; Type 2: Lifestyle-related
• D. Type 1: Insulin therapy; Type 2: Diet modification

Correct answer: A

Rationale: The correct answer is A. Type 1 diabetes is characterized by the absence of insulin production, while Type 2 diabetes involves insulin resistance. Choice B is incorrect because Type 1 diabetes is not related to insulin resistance. Choice C is inaccurate as Type 1 diabetes is autoimmune while Type 2 diabetes is more associated with lifestyle factors. Choice D is not correct since insulin therapy is primarily used in Type 1 diabetes, whereas diet modification is a common approach in managing Type 2 diabetes.

3. What is the best dietary recommendation for a patient with chronic kidney disease?

• A. Low-protein diet
• B. High-protein diet
• C. Low-sodium diet
• D. High-sodium diet

Correct answer: A

Rationale: The correct answer is a low-protein diet for a patient with chronic kidney disease. In chronic kidney disease, the kidneys may have difficulty filtering waste products from protein metabolism, leading to a buildup of toxins in the body. Therefore, reducing protein intake can help lessen the workload on the kidneys. Choices B, C, and D are incorrect. A high-protein diet would increase the workload on the kidneys, while a low-sodium diet is beneficial for conditions like hypertension or heart failure but not specifically targeted for chronic kidney disease. A high-sodium diet can worsen fluid retention and hypertension in patients with kidney disease.

4. A client who is to undergo an exercise stress test is being taught by a nurse. Which of the following statements by the client indicates an understanding of the teaching?

• A. I should eat a large meal 2 hours before the test
• B. I should avoid drinking water before the test
• C. I should stop taking my blood pressure medication
• D. I should report any chest pain during the test

Correct answer: D

Rationale: The correct answer is D: 'I should report any chest pain during the test.' This statement indicates an understanding of the teaching because reporting chest pain during an exercise stress test is crucial as it may signify cardiac distress. Choices A, B, and C are incorrect. Eating a large meal 2 hours before the test is not recommended as it may affect the results. Avoiding drinking water before the test is also not advisable as staying hydrated is important. Stopping blood pressure medication without medical advice can be dangerous, especially before a stress test.

5. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.
