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. A patient is receiving intravenous amphotericin. Which of the following assessments warrants the discontinuation of the antifungal agent?

• A. Sodium level of 138 mEq/L
• B. Hematocrit of 39%
• C. Blood urea nitrogen of 60 mg/dL
• D. AST level of 10 Unit/L

Correct answer: C

Rationale: Intravenous amphotericin can cause nephrotoxicity, leading to increased blood urea nitrogen levels. Elevated blood urea nitrogen (BUN) indicates impaired renal function, which is a known adverse effect of amphotericin. Therefore, a BUN level of 60 mg/dL warrants the discontinuation of the antifungal agent. The other options, such as a sodium level of 138 mEq/L, hematocrit of 39%, and AST level of 10 Unit/L, are within normal ranges and not indicative of the need to discontinue amphotericin therapy.

3. Which of the following mediates humoral immunity?

• A. Natural killer cells
• B. T cells
• C. B cells
• D. Neutrophils

Correct answer: C

Rationale: Humoral immunity is mediated by B cells, not natural killer cells, T cells, or neutrophils. B cells are responsible for producing antibodies, which are essential components of humoral immunity.

4. Which scenario would be an example of a child born with congenital insensitivity to pain?

• A. A child who does not cry when injured and fails to respond to painful stimuli.
• B. A child who cries excessively and has a heightened response to pain.
• C. A child who experiences pain but has difficulty expressing it.
• D. A child who is sensitive to minor stimuli but has a delayed response to severe pain.

Correct answer: A

Rationale: The correct scenario depicting a child with congenital insensitivity to pain is when the child does not cry when injured and fails to respond to painful stimuli. This condition is characterized by the inability to feel and react to pain, resulting in a lack of typical responses such as crying or withdrawal when hurt. Choice B is incorrect as it describes a child with heightened pain sensitivity, opposite to the insensitivity seen in the condition. Choice C is incorrect as it suggests the child feels pain but struggles to communicate it, which is not the case with congenital insensitivity to pain. Choice D is incorrect as it describes a child who is sensitive to minor stimuli and has delayed responses to severe pain, which is not indicative of congenital insensitivity to pain.

5. A woman of childbearing age is diagnosed with breast cancer. She is currently taking hormonal contraceptives. What information should the woman be given regarding the hormonal contraceptives?

• A. The hormonal contraceptives do not affect the course of the disease.
• B. The hormonal contraceptives will stimulate uterine bleeding.
• C. The hormonal contraceptives will impair uterine bleeding.
• D. The hormonal contraceptives will stimulate tumor growth.

Correct answer: A

Rationale: The correct answer is A. Hormonal contraceptives should be discontinued in women diagnosed with breast cancer because they can potentially stimulate cancer growth. Choice B is incorrect as hormonal contraceptives do not stimulate uterine bleeding. Choice C is also incorrect as hormonal contraceptives typically do not impair uterine bleeding. Choice D is incorrect because hormonal contraceptives are not meant to stimulate tumor growth.
