Question 1 of 5
In man the Ebstein-Barr virus is associated with which of the following disease:
Correct Answer: D
Rationale: Epstein-Barr virus (EBV) links to Burkitt's lymphoma (A B-cell malignancy) and infectious mononucleosis (C lymphocytosis, fever), thus D (A & C). Retropharyngeal cancer (B) lacks EBV association HPV or smoking dominate. All' overstates. EBV's oncogenic (Burkitt's) and infectious (mono) roles are key, guiding nursing for serology (e.g., VCA-IgM) and lymphoma staging.

Question 5 of 5
Compared to a normal individual, a patient with idiopathic pulmonary fibrosis, one of the following is expected to be more than normal?
Correct Answer: B
Rationale: Idiopathic pulmonary fibrosis (IPF) is a restrictive lung disease marked by progressive scarring of the lung interstitium, reducing lung elasticity and function. Total lung capacity (TLC) decreases in IPF because fibrotic tissue stiffens the lungs, limiting their expansion. Forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) are both reduced, but the FEV1/FVC ratio remains normal or elevated, unlike in obstructive diseases. Arterial oxygen partial pressure (PaO2) drops due to impaired gas exchange across thickened alveolar walls, leading to hypoxemia. However, total pulmonary vascular resistance (PVR) increases in IPF as fibrosis compresses and obliterates pulmonary capillaries, narrowing the vascular bed and elevating resistance to blood flow. This increase can strain the right heart, potentially causing cor pulmonale. Among the options, only total pulmonary vascular resistance is expected to be higher than normal, aligning with IPF's impact on the pulmonary vasculature rather than lung volumes or oxygenation, which decline.
