Nursing Elites

1. A nurse is reviewing the laboratory results for a client who has Cushing's disease. The nurse should expect the client to have an increase in which of the following laboratory values?

• A. Serum glucose level.
• B. Serum calcium level.
• C. Lymphocyte count.
• D. Serum potassium level.

Correct answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, there is an excess production of cortisol, leading to hyperglycemia. This results in an increase in serum glucose levels. Choices B, C, and D are incorrect because Cushing's disease does not directly affect serum calcium levels, lymphocyte count, or serum potassium levels.

2. A nurse is caring for a client who has hypokalemia. Which of the following clinical findings should the nurse expect?

• A. Hyperactive reflexes.
• B. Strong, bounding pulse.
• C. Decreased bowel sounds.
• D. Increased deep tendon reflexes.

Correct answer: C

Rationale: The correct answer is C: Decreased bowel sounds. In hypokalemia, decreased bowel sounds are common due to slowed peristalsis. Hyperactive reflexes (choice A) and increased deep tendon reflexes (choice D) are more indicative of hyperkalemia. A strong, bounding pulse (choice B) is not typically associated with hypokalemia.

3. A client is scheduled for a 12-lead ECG. Which of the following actions should the nurse include in the plan of care?

• A. Ensure the client is fasting before the test
• B. Provide a warm blanket for the client
• C. Apply cold compresses to the client's chest
• D. Instruct the client to remain still

Correct answer: D

Rationale: During a 12-lead ECG, the client needs to remain still to obtain accurate readings. Therefore, instructing the client to remain still is essential. Choices A, B, and C are incorrect because fasting is not necessary for an ECG, providing a warm blanket is not a standard procedure, and applying cold compresses may interfere with the ECG results.

4. A client with chronic obstructive pulmonary disease (COPD) is being taught by a nurse about measures to improve breathing. Which of the following instructions should the nurse include?

• A. Use pursed-lip breathing during physical activity
• B. Breathe deeply and quickly during exercise
• C. Avoid using the incentive spirometer
• D. Avoid physical activity to conserve energy

Correct answer: A

Rationale: The correct instruction the nurse should include is to 'Use pursed-lip breathing during physical activity.' Pursed-lip breathing is a technique that helps improve breathing efficiency in individuals with COPD by preventing airway collapse and allowing for better air exchange. Choice B is incorrect because breathing deeply and quickly can lead to hyperventilation and worsen symptoms in COPD patients. Choice C is incorrect because the incentive spirometer is a device used to encourage deep breathing and improve lung function, so it should not be avoided. Choice D is incorrect because physical activity is important for maintaining overall health and should be encouraged in a controlled and appropriate manner for individuals with COPD.

5. 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.
