      B)Secretion of wastes
      C)Production of hormones
      D)Filtration of blood
    2. A patient with interstitial lung disease is experiencing hypoxemia. Which mechanism is primarily responsible for the impaired gas exchange?
      A)Thickening of the alveolar-capillary membrane
      B)Increased alveolar ventilation
      C)Enhanced capillary perfusion
      D)Decreased diffusion capacity of CO2
    3. A patient is experiencing muscle cramps and confusion. Blood tests reveal a sodium level of 125 mEq/L Which intervention should the nurse prioritize?
      A)Provide a high-sodium diet.
      B)Administer hypotonic saline solution.
      C)Restrict oral fluid intake.
      D)Encourage the patient to drink more water.
    4. What is the primary role of intrinsic factor in vitamin absorption?
      A)It assists in the absorption of vitamin A in the liver.
      B)It aids in the absorption of vitamin D in the kidneys.
      C)It helps in the absorption of vitamin C in the stomach.
      D)It binds to vitamin B12 to facilitate its absorption in the ileum.

      A)Add fluid and fiber to the diet.
      B)Avoid gas-producing foods.
      C)Request that the provider prescribe a stool softener.
      D)Promote active range-of-motion activities.
    2. Which structure within the nephron is primarily responsible for the filtration of blood?

      B)Loop of Henle
      C)Distal convoluted tubule
      D)Bowman's capsule
    3. A nurse is preparing to administer amoxicillin 350 mg PO. Available is amoxicillin 250 mg/5 mL. How many mL should the nurse administer? (Round to the nearest whole number.)
    4. What is the consequence of intrinsic factor not binding to vitamin B12?
      A)Vitamin B12 is stored in excess in the liver.
      B)Vitamin B12 is not absorbed and can lead to deficiency.
      C)Vitamin B12 is converted to its inactive form.

    Exam Review

    1. A patient with pneumonia presents with hypoxia. Which pathophysiological process is primarily responsible for this condition?
      A)Increased alveolar ventilation
      B)Impaired alveolar gas exchange
      C)Decreased alveolar perfusion
      D)Enhanced diffusion of carbon dioxide
    2. Why is vitamin B12 deficiency common in patients with pernicious anemia?
      A)Intrinsic factor enhances vitamin B12 storage, which is impaired in pernicious anemia.
      B)Due to the lack of intrinsic factor, vitamin B12 cannot be absorbed.
      C)Intrinsic factor is destroyed by liver enzymes, leading to deficiency.
