1. Which of the following accurately describes the pathophysiology of asthma?

• A. Chronic inflammation of the bronchial lining
• B. Narrowing of the airway due to bronchoconstriction
• C. Damage to alveoli reducing lung elasticity
• D. Overproduction of mucus by the goblet cells

Correct answer: B

Rationale: The correct answer is B: "Narrowing of the airway due to bronchoconstriction." In asthma, there is an inflammatory response that leads to bronchoconstriction, causing the airways to narrow and making it difficult to breathe. Choice A is incorrect as chronic inflammation is a feature of asthma but not the primary pathophysiological mechanism. Choice C is incorrect as damage to alveoli is more characteristic of conditions like emphysema. Choice D is incorrect as overproduction of mucus is a feature of chronic bronchitis, not asthma.

2. What can multiple dark bands on the nails indicate?

• A. They are considered a normal variant.
• B. They can be associated with malignant melanoma.
• C. They are indicative of a nail fungus.
• D. They are associated with aging.

Correct answer: B

Rationale: Multiple dark bands on the nails can be associated with malignant melanoma, a serious type of skin cancer. While dark bands on the nails can sometimes be a normal variant, they should not be ignored as they could also be a sign of a serious condition like melanoma. Nail fungus typically presents with different symptoms such as thickened, discolored, or brittle nails. Dark bands on the nails are not directly associated with aging.

3. Cushing syndrome is characterized by which disorder?

• A. Hypocortisolism
• B. Exophthalmos
• C. Hypercortisolism
• D. Hyperpigmentation

Correct answer: C

Rationale: Cushing syndrome is characterized by hypercortisolism, which is an excessive amount of cortisol in the body. Choice A, 'Hypocortisolism,' is incorrect as Cushing syndrome is associated with elevated cortisol levels. Choice B, 'Exophthalmos,' refers to bulging eyes and is not a characteristic feature of Cushing syndrome. Hyperpigmentation, as mentioned in choice D, can be present in Cushing syndrome due to increased ACTH levels stimulating melanocytes, but it is not the defining characteristic of the syndrome.

4. A patient is prescribed tadalafil (Cialis) for erectile dysfunction. What condition would contraindicate the use of this medication?

• A. History of hypertension
• B. Use of nitrates
• C. Use of antihypertensive medications
• D. History of peptic ulcer disease

Correct answer: B

Rationale: The correct answer is B: 'Use of nitrates.' Tadalafil (Cialis) is contraindicated in patients using nitrates due to the risk of severe hypotension. Nitrates and tadalafil both cause vasodilation, leading to a synergistic effect that can result in a dangerous drop in blood pressure. Choices A, C, and D are incorrect because a history of hypertension, the use of antihypertensive medications, and a history of peptic ulcer disease are not direct contraindications for tadalafil use.

5. Which of the following is a factor that leads to increased risk for dehydration in the elderly?

• A. More insensible losses
• B. Increase in muscle mass
• C. Decline in kidney function
• D. Decrease in fat

Correct answer: C

Rationale: The correct answer is C: Decline in kidney function. As people age, their kidneys may not work as effectively in conserving water and concentrating urine, leading to a higher risk of dehydration. Choice A is incorrect because more insensible losses do not directly relate to an increased risk of dehydration in the elderly. Choice B, an increase in muscle mass, is not a factor that leads to dehydration. Choice D, a decrease in fat, is also not a direct factor contributing to dehydration in the elderly.
