Pathophysiology Practice Questions

1. A student nurse was asked which of the following best describes dementia. Which of the following best describes the condition?

A. Memory loss as a natural consequence of aging
B. Difficulty coping with physical and psychological changes
C. Severe cognitive impairment that occurs rapidly
D. Loss of cognitive abilities, impairing the ability to perform activities of daily living

Correct answer: D

Rationale: The correct answer is D. Dementia is characterized by a loss of cognitive abilities that impairs the individual's capacity to perform activities of daily living. Choice A is incorrect because dementia is not simply memory loss related to aging but involves broader cognitive deficits. Choice B is incorrect as it does not capture the comprehensive cognitive decline seen in dementia. Choice C is incorrect as dementia typically progresses gradually rather than rapidly, and it is not solely about severe cognitive impairment but also impacts daily functioning.

2. What is the treatment for patients with hemophilia A?

A. Chemotherapy
B. Factor VIII replacement
C. Heparin administration
D. Bone marrow transplant

Correct answer: B

Rationale: The correct treatment for patients with hemophilia A is Factor VIII replacement. Hemophilia A is a genetic disorder where there is a deficiency in clotting factor VIII. Therefore, replacing this factor is crucial in managing and preventing bleeding episodes. Choice A, chemotherapy, is not the correct treatment for hemophilia A. Choice C, heparin administration, is not recommended as it can further increase the risk of bleeding in patients with hemophilia. Choice D, bone marrow transplant, is not a standard treatment for hemophilia A.

3. A patient with breast cancer is prescribed tamoxifen (Nolvadex). What critical information should the nurse provide during patient education?

A. Tamoxifen may increase the risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots.
B. Tamoxifen may decrease the risk of osteoporosis, so adequate calcium intake is important.
C. Tamoxifen may cause weight gain, so patients should monitor their diet.
D. Tamoxifen may increase the risk of breast cancer, so regular mammograms are essential.

Correct answer: A

Rationale: When a patient is prescribed tamoxifen, a critical piece of information that the nurse should provide during patient education is that tamoxifen may increase the risk of venous thromboembolism. Therefore, patients should be educated about the signs and symptoms of blood clots and advised to seek immediate medical attention if they occur. Choice B is incorrect because tamoxifen does not decrease the risk of osteoporosis. Choice C is incorrect as weight gain is a possible side effect of tamoxifen, but it is not a critical piece of information compared to the risk of venous thromboembolism. Choice D is incorrect because tamoxifen is actually used to treat breast cancer, not increase its risk.

4. 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.

5. Which of the following characteristics is common in both malignant and benign tumors?

A. Uncontrolled cell growth
B. Rapid growth
C. Metastasis
D. Invasion of surrounding tissue

Correct answer: A

Rationale: The correct answer is A: Uncontrolled cell growth. This characteristic is common to both malignant and benign tumors. Benign tumors are non-cancerous growths that do not invade nearby tissue or spread to other parts of the body. Therefore, choices B, C, and D are incorrect. Rapid growth, metastasis, and invasion of surrounding tissue are characteristics typically associated with malignant tumors.
