1. How should a healthcare professional assess a patient with hyperkalemia?

A. Monitor ECG and administer insulin
B. Monitor blood glucose levels and provide fluids
C. Monitor for muscle weakness and administer calcium gluconate
D. Monitor electrolyte levels and provide potassium supplements

Correct answer: A

Rationale: Corrected Question: When assessing a patient with hyperkalemia, monitoring the ECG and administering insulin are crucial steps. Hyperkalemia can affect the heart's function, leading to life-threatening arrhythmias. Monitoring the ECG helps in identifying any cardiac abnormalities associated with high potassium levels. Administering insulin, along with glucose, helps shift potassium from the bloodstream into the cells, temporarily lowering the potassium levels. Choice B is incorrect because monitoring blood glucose levels and providing fluids are not the primary interventions for hyperkalemia. Choice C is incorrect as monitoring for muscle weakness and administering calcium gluconate are not the first-line treatments for hyperkalemia. Calcium gluconate may be used in specific situations to stabilize cardiac cell membranes in severe cases of hyperkalemia. Choice D is incorrect because monitoring electrolyte levels and providing potassium supplements would worsen hyperkalemia, as the patient already has elevated potassium levels and does not require additional potassium supplementation.

2. What is the proper technique for measuring a patient's blood pressure?

A. Place the cuff at heart level and listen for Korotkoff sounds
B. Ensure the patient is in a seated position and inflate the cuff to 180 mmHg
C. Use a manual sphygmomanometer and measure blood pressure on both arms
D. Monitor pulse rate and apply pressure to the brachial artery

Correct answer: A

Rationale: The correct technique for measuring blood pressure involves placing the cuff at heart level to ensure accurate readings. Listening for Korotkoff sounds helps determine the systolic and diastolic pressures. Choice B is incorrect as inflating the cuff to 180 mmHg is excessive and can lead to inaccurate readings. Choice C is incorrect as it is unnecessary to measure blood pressure on both arms unless there is a specific medical reason to do so. Choice D is incorrect as monitoring pulse rate and applying pressure to the brachial artery are not part of the standard blood pressure measurement technique.

3. A client with heart failure is receiving furosemide. Which of the following assessment findings indicates that the medication is effective?

A. Elevated blood pressure.
B. Absence of adventitious breath sounds.
C. Weight gain of 1.4 kg (3 lb) in 24 hr.
D. Decreased urine output.

Correct answer: B

Rationale: The absence of adventitious breath sounds indicates that furosemide is effective in managing heart failure. Adventitious breath sounds such as crackles indicate fluid accumulation in the lungs, a common complication of heart failure. Therefore, the absence of these abnormal sounds suggests that furosemide is effectively reducing fluid overload. Elevated blood pressure (choice A) is not a desired outcome in heart failure management. Weight gain (choice C) and decreased urine output (choice D) are signs of fluid retention and ineffective diuresis, indicating that furosemide is not working effectively.

4. 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.

5. A nurse is caring for a client who has been diagnosed with hyperkalemia. Which of the following findings should the nurse expect?

A. Muscle weakness
B. Nausea
C. Increased thirst
D. Restlessness

Correct answer: A

Rationale: Muscle weakness is a characteristic finding in hyperkalemia. High levels of potassium can affect the normal function of muscles, leading to weakness. Nausea and increased thirst are not typically associated with hyperkalemia. Restlessness is more commonly seen in conditions such as hypoxia or anxiety, not specifically in hyperkalemia.
