1. An older adult patient comes to the clinic complaining of not being able to do what he used to be able to. You know that normal changes associated with aging include:

• A. Improved blood flow
• B. Slowed metabolic rate
• C. Increased brain weight
• D. Improved nerve fiber conduction

Correct answer: B

Rationale: Normal changes associated with aging include a slowed metabolic rate and decreased brain weight. Option A, 'Improved blood flow,' is incorrect as aging is generally associated with reduced vascular health rather than improved blood flow. Option D, 'Improved nerve fiber conduction,' is incorrect as aging typically leads to a decline in nerve function rather than improvement.

2. Cellular swelling is:

• A. Irreversible
• B. Evident early in all types of cellular injury
• C. Manifested by decreased intracellular sodium
• D. None of the above is correct

Correct answer: B

Rationale: Cellular swelling is indeed evident early in all types of cellular injury. This occurs due to the influx of water into the cell, leading to swelling. Choice A is incorrect because cellular swelling is reversible if the injury is not severe. Choice C is incorrect because cellular swelling is not manifested by decreased intracellular sodium; in fact, it is associated with increased intracellular sodium due to water influx. Choice D is incorrect as option B is the correct statement.

3. What is the primary cause of angina?

• A. Increased oxygen demand by the heart
• B. Obstruction of the coronary arteries
• C. Lack of oxygen in the lungs
• D. Decreased blood supply to the liver

Correct answer: B

Rationale: The correct answer is B: Obstruction of the coronary arteries. Angina is primarily caused by a reduced blood flow to the heart due to blockages or narrowing in the coronary arteries. Choice A is incorrect because while increased oxygen demand can contribute to angina symptoms, it is not the primary cause. Choice C is incorrect as angina is not caused by a lack of oxygen in the lungs. Choice D is also incorrect as angina is not related to decreased blood supply to the liver.

4. A child's thymus gland is fully formed and proportionately larger than an adult's. Which of the following processes that contribute to immunity takes place in the thymus gland?

• A. Differentiation of B cells
• B. Production of natural killer (NK) cells
• C. Proliferation of T cells
• D. Filtration of antigens from the blood

Correct answer: C

Rationale: The correct answer is C: Proliferation of T cells. The thymus gland is responsible for the maturation and proliferation of T cells, which play a crucial role in adaptive immunity. Option A, differentiation of B cells, is incorrect because B cell maturation primarily occurs in the bone marrow. Option B, production of natural killer (NK) cells, is incorrect as NK cells are mainly produced in the bone marrow and lymph nodes. Option D, filtration of antigens from the blood, is incorrect as antigen filtration is not a primary function of the thymus gland.

5. A hospital patient's complex medical history includes a recent diagnosis of kidney cancer. Which of the following medications is used to treat metastatic kidney cancer?

• A. Filgrastim (Neupogen)
• B. Aldesleukin (Proleukin)
• C. Interferon alfa-2b (Intron A)
• D. Darbepoetin alfa (Aranesp)

Correct answer: B

Rationale: The correct answer is B: Aldesleukin (Proleukin). Aldesleukin is a medication used in the treatment of metastatic kidney cancer. It is a recombinant interleukin-2 that works by stimulating the immune system to attack cancer cells. Choice A, Filgrastim, is a medication used to stimulate the production of white blood cells. Choice C, Interferon alfa-2b, is used in the treatment of certain cancers but not specifically metastatic kidney cancer. Choice D, Darbepoetin alfa, is used to treat anemia by stimulating red blood cell production and is not indicated for metastatic kidney cancer.
