1. Which type of lymphocyte recognizes and eliminates virus-infected cells and cancerous cells?

• A. Neutrophils
• B. Macrophages
• C. Natural killer cells
• D. Langerhans cells

Correct answer: C

Rationale: Natural killer cells are a type of lymphocyte that plays a crucial role in recognizing and eliminating virus-infected cells and cancerous cells. Neutrophils (Choice A) are a type of white blood cell involved in fighting infections, mainly through phagocytosis. Macrophages (Choice B) are another type of white blood cell that engulfs and digests cellular debris and pathogens. Langerhans cells (Choice D) are a type of dendritic cell found in the skin and mucosa, primarily involved in antigen presentation.

2. A male patient is being treated with sildenafil (Viagra) for erectile dysfunction. What condition would contraindicate the use of this medication?

• A. Peptic ulcer disease
• B. History of myocardial infarction
• C. Recent use of antihypertensive medications
• D. Use of nitrates

Correct answer: D

Rationale: The correct answer is D: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, and the combination can lead to a dangerous drop in blood pressure. Choice A, peptic ulcer disease, is not a contraindication for sildenafil use. Choice B, a history of myocardial infarction, is not a contraindication unless the patient is also taking nitrates. Choice C, recent use of antihypertensive medications, is not a contraindication but requires caution as the combination can lead to additive effects lowering blood pressure.

3. Which of the following disturbances would cause a client to experience gout?

• A. Serotonin receptors
• B. Uric acid metabolism
• C. Liver function
• D. Cardiac function

Correct answer: B

Rationale: Gout is caused by a disturbance in uric acid metabolism, leading to the accumulation of uric acid crystals in joints. Serotonin receptors (Choice A) are not related to gout. Liver function (Choice C) is important for metabolism but is not directly linked to gout development. Cardiac function (Choice D) is primarily related to the heart's functioning and not associated with gout.

4. Which of the following is the most likely indication for the use of immunosuppressant agents?

• A. Intractable seizure disorders
• B. Increased intracranial pressure
• C. Organ transplantation
• D. HIV/AIDS with multiple drug resistance

Correct answer: C

Rationale: The correct answer is C: Organ transplantation. Immunosuppressant agents are commonly used in organ transplant recipients to prevent organ rejection by suppressing the immune system. Choices A, B, and D are incorrect. Intractable seizure disorders are often managed with antiepileptic drugs, increased intracranial pressure is managed through various means like surgery and medications, and HIV/AIDS with multiple drug resistance is typically treated with antiretroviral therapy, not immunosuppressant agents.

5. A 22-year-old was recently diagnosed with acquired immunodeficiency syndrome (AIDS). Which decreased lab finding would be expected to accompany this virus?

• A. CD4 helper T cells
• B. CD8 helper T cells
• C. CDC cells
• D. CDC10 cells

Correct answer: A

Rationale: In a person diagnosed with AIDS, a decrease in CD4 helper T cells is expected. These cells are critical for the immune system's proper functioning, and their reduction weakens the body's ability to fight infections. CD8 helper T cells (Choice B) are not typically decreased in AIDS. CDC cells (Choice C) and CDC10 cells (Choice D) are not relevant terms in this context, making them incorrect choices.
