1. What is reperfusion injury?

• A. Healing bone tissue after fracture
• B. Skin wound tunneling and shear
• C. Secondary injury after reestablishing blood flow
• D. Injury after blood transfusion

Correct answer: C

Rationale: Reperfusion injury refers to the secondary injury that occurs after blood flow is reestablished following ischemia. This process leads to tissue damage due to the sudden reintroduction of oxygen and nutrients, causing oxidative stress, inflammation, and cell death. Choice A is incorrect as it describes the normal healing process of bone tissue after a fracture. Choice B is incorrect as it describes specific mechanisms related to skin wounds, not reperfusion injury. Choice D is incorrect as it refers to a different concept, which is adverse reactions or complications that can occur after a blood transfusion, not reperfusion injury.

2. A nurse is teaching a patient about the use of testosterone gel for the treatment of hypogonadism. What important instruction should the nurse provide?

• A. Apply the gel after showering, and allow it to dry completely before dressing.
• B. Apply the gel to the genitals for maximum absorption.
• C. Apply the gel before bedtime to enhance absorption during sleep.
• D. Apply the gel to the face and neck for improved results.

Correct answer: A

Rationale: The correct instruction is to apply testosterone gel after showering and allow it to dry completely before dressing. This helps prevent the transfer of the gel to others and ensures proper absorption. Choice B is incorrect because the gel should not be applied to the genitals. Choice C is incorrect as there is no specific benefit to applying the gel before bedtime. Choice D is incorrect as the gel should not be applied to the face and neck for the treatment of hypogonadism.

3. Which of the following characterizes ductal carcinoma in situ?

• A. It is less common than lobular carcinoma in situ.
• B. Malignant cells have not invaded the stroma.
• C. It is considered a cancer precursor.
• D. Malignant cells have not invaded the stroma; it is considered a cancer precursor and has a higher risk for invasive cancer compared to lobular carcinoma in situ.

Correct answer: D

Rationale: The correct answer is that ductal carcinoma in situ is characterized by malignant cells that have not invaded the stroma, making it a cancer precursor with a higher risk for invasive cancer compared to lobular carcinoma in situ. Choice A is incorrect because ductal carcinoma in situ is more common than lobular carcinoma in situ. Choice B is incorrect as it only partially describes ductal carcinoma in situ without mentioning its potential for progression to invasive cancer. Choice C is incorrect because it does not capture the complete characteristics of ductal carcinoma in situ, which include the risk for invasive cancer.

4. What causes type I diabetes?

• A. Overproduction of insulin from the beta cells of the pancreas
• B. Destruction of the beta cells within the pancreas, resulting in an inability to produce insulin
• C. Loss of insulin receptors on the target cells, resulting in insulin resistance
• D. A pituitary tumor in the brain, resulting in increased antidiuretic hormone production

Correct answer: B

Rationale: Type I diabetes is caused by the destruction of the beta cells in the pancreas, leading to an inability to produce insulin. This results in a lack of insulin, leading to hyperglycemia. Choice A is incorrect as type I diabetes is characterized by a deficiency of insulin production, not overproduction. Choice C describes the pathophysiology of type 2 diabetes, where insulin receptors become less responsive to insulin. Choice D is unrelated to type I diabetes as it describes a pituitary tumor causing increased antidiuretic hormone production.

5. Manifestations of Cushing syndrome include:

• A. truncal obesity with thin extremities.
• B. enlargement of face, hands, and feet.
• C. cachexia.
• D. thick scalp hair.

Correct answer: A

Rationale: The correct manifestation of Cushing syndrome is truncal obesity with thin extremities. This occurs due to the redistribution of fat to the face, neck, and abdomen, while the arms and legs remain thin. Choice B, enlargement of face, hands, and feet, is more indicative of acromegaly. Choice C, cachexia, refers to extreme weight loss and muscle wasting, which is typically not seen in Cushing syndrome. Choice D, thick scalp hair, is not a typical manifestation of Cushing syndrome.
