1. Which assessment finding is expected with myxedema?
- A. Increased pulse rate
- B. Decreased temperature
- C. Fine tremors
- D. Weight loss
Correct answer: B
Rationale: Myxedema is characterized by a decreased metabolic rate, leading to manifestations such as decreased temperature. Therefore, the correct assessment finding expected with myxedema is a decreased temperature. Choices A, C, and D are incorrect because myxedema typically presents with a decreased pulse rate, not an increased pulse rate, absence of fine tremors (which are more common in hyperthyroidism), and weight gain rather than weight loss.
2. What are the key differences between viral and bacterial infections?
- A. Viral infections typically last longer than bacterial infections.
- B. Bacterial infections typically cause high fever.
- C. Both bacterial and viral infections cause rashes.
- D. Viral infections cause sudden onset of symptoms.
Correct answer: A
Rationale: The correct answer is A. Viral infections typically last longer than bacterial infections. This is because viral infections often require the body's immune system to fight off the virus, leading to a longer duration of illness. Bacterial infections, on the other hand, often cause a rapid onset of symptoms due to the toxins produced by bacteria. Choice B is incorrect because not all bacterial infections cause high fever. Choice C is incorrect because rashes can be caused by both bacterial and viral infections, but not always. Choice D is incorrect because while some viral infections may cause a sudden onset of symptoms, it is not a key distinguishing factor between viral and bacterial infections.
3. When providing discharge instructions for a client with home oxygen, what safety measure should the nurse emphasize?
- A. Prohibit smoking near oxygen equipment
- B. Ensure the client uses non-flammable bedding
- C. Ensure oxygen tanks are stored upright
- D. Keep the oxygen equipment at least 6 feet away from heat sources
Correct answer: D
Rationale: The correct answer is to keep the oxygen equipment at least 6 feet away from heat sources. Placing oxygen equipment near heat sources can lead to fire hazards due to the oxygen's combustible nature. Option A is the correct safety measure as smoking near oxygen equipment can cause fires due to oxygen's flammable properties. Option B regarding the use of non-flammable bedding is not directly related to oxygen safety. Option C is important for proper oxygen tank functioning but is not as critical as keeping the equipment away from heat sources to prevent fires.
4. A nurse is assessing a client who has a calcium level of 8.0 mg/dL. Which of the following findings should the nurse expect?
- A. Constipation
- B. Absent deep-tendon reflexes
- C. Nausea and vomiting
- D. Tingling of the extremities
Correct answer: D
Rationale: Correct! A calcium level of 8.0 mg/dL indicates hypocalcemia. Hypocalcemia can lead to increased neuromuscular excitability, manifesting as tingling of the extremities. Choices A, B, and C are incorrect findings associated with other electrolyte imbalances or conditions and are not typically related to hypocalcemia. Constipation is commonly seen in hypokalemia, absent deep-tendon reflexes are associated with hypermagnesemia, and nausea and vomiting are more indicative of hypercalcemia.
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.
