1. What are the key signs of hyperglycemia?

• A. Increased thirst and frequent urination
• B. Decreased appetite and low blood pressure
• C. Weight loss and nausea
• D. Increased sweating and confusion

Correct answer: A

Rationale: The correct answer is A: Increased thirst and frequent urination. These are classic signs of hyperglycemia, indicating elevated blood sugar levels. Choice B is incorrect as hyperglycemia usually presents with increased appetite rather than decreased appetite and low blood pressure. Choice C is incorrect as weight loss is more commonly associated with uncontrolled diabetes rather than hyperglycemia. Choice D is incorrect as increased sweating and confusion are not typical signs of hyperglycemia.

2. How should a healthcare professional manage a patient with fluid overload?

• A. Restrict fluids and administer diuretics
• B. Increase fluid intake and provide oral diuretics
• C. Administer antibiotics and monitor weight
• D. Monitor weight and provide a low-sodium diet

Correct answer: A

Rationale: Corrected Question: When managing a patient with fluid overload, the appropriate approach involves restricting fluids and administering diuretics. This strategy helps remove excess fluid from the body and prevent complications associated with fluid overload. Choice B suggesting increasing fluid intake is incorrect as it would worsen the condition. Choice C, administering antibiotics, is unrelated to managing fluid overload. Choice D, monitoring weight and providing a low-sodium diet, is helpful but not as effective as fluid restriction and diuretics in managing fluid overload.

3. A nurse is teaching a client who is to undergo total knee arthroplasty about postoperative care. Which of the following instructions should the nurse include?

• A. Apply heat to the affected knee
• B. Avoid placing pillows under the knee
• C. Avoid moving the knee for 2-3 days
• D. Apply ice to the affected knee for 24-48 hours

Correct answer: D

Rationale: The correct answer is to apply ice to the affected knee for 24-48 hours. Applying ice helps to reduce inflammation and pain after knee surgery, promoting healing. Choice A is incorrect because heat is not recommended postoperatively, as it can increase swelling. Choice B is incorrect because pillows should be placed under the knee to keep it elevated. Choice C is incorrect because early mobilization is essential for preventing complications such as blood clots.

4. 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.

5. What are the signs and symptoms of a pulmonary embolism?

• A. Sudden shortness of breath
• B. Chest pain
• C. Cough with blood
• D. All of the above

Correct answer: D

Rationale: A pulmonary embolism can manifest with sudden shortness of breath, chest pain, and coughing up blood. These symptoms are classic presentations of a pulmonary embolism due to the blockage of blood flow to the lungs. Therefore, the correct answer is 'All of the above.' Each symptom alone can be seen in various other conditions, but when occurring together, they strongly suggest a pulmonary embolism. Sudden shortness of breath is due to decreased oxygenation, chest pain can result from the strain on the heart, and coughing with blood may indicate damage to the lung tissue. Choosing any single symptom would not encompass the full range of presentations seen in a pulmonary embolism.
