1. Which of the following chronic inflammatory skin disorders is characterized by angiogenesis, immune cell activation (particularly T cells), and keratinocyte proliferation?

• A. Psoriasis
• B. Melanoma
• C. Atopic dermatitis
• D. Urticaria

Correct answer: A

Rationale: Psoriasis is the correct answer. Psoriasis is a chronic inflammatory skin disorder characterized by angiogenesis, immune cell activation (particularly T cells), and keratinocyte proliferation. Choice B, Melanoma, is a type of skin cancer involving melanocytes, not characterized by the features mentioned. Choice C, Atopic dermatitis, is a different inflammatory skin condition associated with pruritus and eczematous lesions, not primarily characterized by angiogenesis. Choice D, Urticaria, is a skin condition characterized by hives and wheals due to histamine release, not typically involving the features mentioned in the question.

2. What is a common cause of a pulmonary embolism?

• A. An autoimmune disorder
• B. A venous blood clot from the lower extremity
• C. An increase in intracranial pressure
• D. Hypotension

Correct answer: B

Rationale: A pulmonary embolism is commonly caused by a blood clot that originates in the venous system of the lower extremity and travels to the lungs, blocking blood flow. This clot is known as a venous thromboembolism. An autoimmune disorder (Choice A) is not typically associated with pulmonary embolism. Intracranial pressure (Choice C) refers to pressure inside the skull and is unrelated to pulmonary embolism. Hypotension (Choice D) is low blood pressure and is not a common cause of pulmonary embolism.

3. Which of the following hormones helps to raise the blood sugar level to help maintain homeostasis?

• A. Antidiuretic hormone (ADH)
• B. Insulin
• C. Glucagon
• D. Thyroxine

Correct answer: C

Rationale: The correct answer is C, Glucagon. Glucagon helps raise blood sugar levels by stimulating the liver to release stored glucose into the bloodstream, thus aiding in maintaining homeostasis. Antidiuretic hormone (ADH), choice A, functions in regulating water balance in the body, not blood sugar levels. Insulin, choice B, lowers blood sugar levels by facilitating glucose uptake by cells. Thyroxine, choice D, is a hormone produced by the thyroid gland that regulates metabolism and has no direct effect on blood sugar levels.

4. What common symptom should be assessed in individuals with immunodeficiency?

• A. Anemia
• B. Recurrent infections
• C. Hypersensitivity
• D. Autoantibody production

Correct answer: B

Rationale: Recurrent infections are a hallmark symptom of immunodeficiency. Individuals with impaired immune systems are more susceptible to recurrent infections due to their compromised ability to fight off pathogens. Anemia (Choice A) is not a direct symptom of immunodeficiency but can be a consequence of chronic diseases. Hypersensitivity (Choice C) refers to exaggerated immune responses rather than impaired immune function. Autoantibody production (Choice D) is not typically a primary symptom of immunodeficiency but may be seen in certain autoimmune conditions.

5. What best describes sepsis?

• A. An overwhelming allergic reaction
• B. Severe inflammatory response to a pathogen's endotoxins
• C. Unknown causes resulting in hypertension
• D. Poor nursing and health care provider interventions

Correct answer: B

Rationale: The correct answer is B. Sepsis is a severe inflammatory response to a pathogen's endotoxins, leading to widespread infection and organ dysfunction. Choice A is incorrect as sepsis is not primarily an allergic reaction. Choice C is incorrect as sepsis is not characterized by unknown causes resulting in hypertension. Choice D is incorrect as sepsis is a medical condition and not solely caused by poor nursing or healthcare provider interventions.
