1. 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.

2. How should a healthcare professional manage a patient with a suspected stroke?

• A. Monitor for changes in neurological status and administer thrombolytics
• B. Monitor for speech difficulties and administer oxygen
• C. Provide IV fluids and monitor blood pressure
• D. Administer pain relief and monitor for respiratory failure

Correct answer: A

Rationale: Corrected Rationale: When managing a patient with a suspected stroke, it is crucial to monitor for changes in neurological status as this can provide important information about the patient's condition. Administering thrombolytics, if indicated, is a critical intervention in the acute phase of an ischemic stroke to help dissolve blood clots and restore blood flow to the brain. This choice is the correct answer because it addresses the immediate management needs of a patient with a suspected stroke. Choices B, C, and D are incorrect because while monitoring for speech difficulties, administering oxygen, providing IV fluids, monitoring blood pressure, administering pain relief, and monitoring for respiratory failure are important aspects of patient care, they are not the primary interventions for managing a suspected stroke.

3. A client is being taught about taking warfarin to treat atrial fibrillation. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will take this medication on an empty stomach.
• B. If I forget to take a dose, I can take it later on the same day.
• C. I will skip my dose if I forget to take it.
• D. I can take an additional dose if I miss one.

Correct answer: B

Rationale: The correct answer is B because taking warfarin later on the same day if a dose is missed helps maintain therapeutic levels. Choice A is incorrect because warfarin should be taken with food to enhance absorption. Choice C is incorrect as skipping a dose can lead to fluctuations in warfarin levels. Choice D is incorrect as taking an additional dose can increase the risk of bleeding.

4. A nurse is caring for a client who has chronic obstructive pulmonary disease (COPD). Which of the following interventions should the nurse include in the plan of care?

• A. Administer oxygen at 2L/min via nasal cannula
• B. Encourage pursed-lip breathing
• C. Position the client in high Fowler's position
• D. Encourage deep breathing and coughing

Correct answer: B

Rationale: The correct intervention for a client with COPD is to encourage pursed-lip breathing. Pursed-lip breathing helps improve oxygenation by preventing airway collapse, slowing down the breathing rate, and promoting better gas exchange. Administering oxygen at 2L/min via nasal cannula is not the first-line intervention as it can cause oxygen toxicity in COPD patients. Positioning the client in high Fowler's position may improve ventilation but does not specifically address the breathing technique required for COPD. Encouraging deep breathing and coughing is generally not recommended for clients with COPD as it can lead to air trapping and increased work of breathing.

5. A nurse is caring for a client who has a serum sodium level of 125 mEq/L. Which of the following findings should the nurse expect?

• A. Numbness of the extremities.
• B. Abdominal cramping.
• C. Bradycardia.
• D. Positive Chvostek's sign.

Correct answer: B

Rationale: Abdominal cramping is a common manifestation of hyponatremia, as the sodium imbalance affects muscle function. Numbness of the extremities (Choice A) is more commonly associated with electrolyte imbalances such as hypocalcemia. Bradycardia (Choice C) is not typically a direct manifestation of hyponatremia. Positive Chvostek's sign (Choice D) is related to hypocalcemia, not hyponatremia.
