Nursing Elites

1. How should a healthcare professional respond to a patient with hypokalemia?

• A. Administer potassium supplements and monitor ECG
• B. Restrict fluid intake and provide a high-sodium diet
• C. Monitor sodium levels and provide insulin therapy
• D. Provide calcium supplements and monitor for hyperkalemia

Correct answer: A

Rationale: Hypokalemia is managed by administering potassium supplements to correct the low potassium levels in the body. Monitoring the ECG is essential because low potassium levels can lead to cardiac arrhythmias. Choice B is incorrect as restricting fluid intake and providing a high-sodium diet are not appropriate for managing hypokalemia. Choice C is incorrect because hypokalemia involves low potassium levels, not sodium levels, and insulin therapy does not directly address this issue. Choice D is incorrect as calcium supplements are not indicated for hypokalemia, and monitoring for hyperkalemia is not relevant in this case.

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. What is the appropriate intervention for a patient experiencing hypovolemic shock?

• A. Administer IV fluids
• B. Monitor blood pressure
• C. Place the patient in Trendelenburg position
• D. Administer oxygen

Correct answer: A

Rationale: The correct intervention for a patient experiencing hypovolemic shock is to administer IV fluids. In hypovolemic shock, there is a significant loss of circulating blood volume leading to inadequate perfusion to tissues. Administering IV fluids is crucial to restore blood volume and improve tissue perfusion. Monitoring blood pressure (choice B) is important but not the primary intervention in hypovolemic shock. Placing the patient in Trendelenburg position (choice C) can worsen outcomes by increasing intracranial pressure and is no longer recommended. Administering oxygen (choice D) is beneficial for many conditions but does not address the underlying issue of inadequate circulating blood volume in hypovolemic shock.

4. What are the nursing priorities for a patient experiencing an asthma exacerbation?

• A. Administer a bronchodilator
• B. Encourage deep breathing
• C. Provide oxygen therapy
• D. Monitor oxygen saturation

Correct answer: A

Rationale: The correct nursing priority for a patient experiencing an asthma exacerbation is to administer a bronchodilator. Bronchodilators help in relieving bronchoconstriction and improving breathing. While encouraging deep breathing, providing oxygen therapy, and monitoring oxygen saturation are essential aspects of managing asthma exacerbation, the priority is to administer a bronchodilator to address the acute bronchoconstriction.

5. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.
