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. A nurse is caring for a client who is in the early stages of hypovolemic shock. Which of the following findings should the nurse expect?

• A. Heart rate 60/min
• B. Increased urinary output
• C. Increased respiratory rate
• D. Hypothermia

Correct answer: C

Rationale: In the early stages of hypovolemic shock, the body initiates compensatory mechanisms to maintain perfusion. One of these mechanisms is an increased respiratory rate to improve oxygen delivery. This helps to offset the decreased circulating blood volume. A heart rate of 60/min (choice A) is not expected in hypovolemic shock; instead, tachycardia is a common finding due to the body's attempt to maintain cardiac output. Increased urinary output (choice B) is not typically seen in hypovolemic shock as the body tries to conserve fluid. Hypothermia (choice D) is usually a late sign of shock when the body's compensatory mechanisms are failing, and perfusion is severely compromised.

3. What are the signs and symptoms of fluid overload?

• A. Edema, shortness of breath, weight gain
• B. High blood pressure and jugular venous distention
• C. Low blood pressure and cyanosis
• D. Tachycardia and dizziness

Correct answer: A

Rationale: The correct signs and symptoms of fluid overload include edema, shortness of breath, and weight gain. Edema is the abnormal accumulation of fluid causing swelling, shortness of breath can occur due to fluid accumulating in the lungs, and weight gain is often seen as a result of excess fluid retention. Choices B, C, and D are incorrect because high blood pressure and jugular venous distention are more indicative of conditions like heart failure, while low blood pressure and cyanosis are seen in conditions like shock or poor perfusion. Tachycardia and dizziness are not typical signs of fluid overload.

4. A healthcare professional is collecting data from a client who has iron deficiency anemia. Which of the following findings should the healthcare professional expect?

• A. Increased energy
• B. Easy bruising
• C. Pale conjunctiva
• D. Weight gain

Correct answer: C

Rationale: Pale conjunctiva is a common sign of iron deficiency anemia due to reduced hemoglobin levels. This results in decreased oxygen-carrying capacity, leading to tissue hypoxia and pallor. 'Increased energy' (choice A) is not typically associated with iron deficiency anemia, as fatigue and weakness are common symptoms. 'Easy bruising' (choice B) is more characteristic of platelet disorders or vitamin deficiencies rather than iron deficiency anemia. 'Weight gain' (choice D) is not a typical finding in iron deficiency anemia; in fact, weight loss is more common due to decreased appetite and overall weakness.

5. What are the common complications of diabetes, and how should they be managed?

• A. Retinopathy and nephropathy; manage with regular screening
• B. Neuropathy and cardiovascular disease; manage with medication
• C. Foot ulcers and hypertension; manage with proper foot care
• D. Hypertension and liver disease; manage with insulin therapy

Correct answer: A

Rationale: The correct answer is A. Common complications of diabetes include retinopathy (damage to the retina) and nephropathy (kidney damage). These complications can be managed effectively with regular screening to detect any signs early on. Choice B is incorrect as neuropathy and cardiovascular disease are other complications of diabetes but are managed through various treatments and lifestyle modifications, not just medication. Choice C is incorrect as although foot ulcers and hypertension are associated with diabetes, the management involves proper foot care practices and blood pressure control, respectively. Choice D is incorrect as hypertension and liver disease are not the typical complications of diabetes, and insulin therapy is not the primary management for these conditions.
