question 11 of 20
which finding indicates that hypertension is progressing to target organ damage?

• chest x - ray showing pneumonia
• urine output of 60 ml over 2 hours
• retinal blood vessel damage
• blood urea nitrogen concentration of 12 mg/dl

Explanation:

To determine which finding indicates hypertension - related target organ damage, we analyze each option:

• Chest X - ray showing pneumonia: Pneumonia is an infection of the lungs and not directly related to hypertension - induced target organ damage.
• Urine output of 60 mL over 2 hours: A urine output of 30 mL/hour (60 mL over 2 hours is 30 mL/hour) is within the normal range (normal urine output is about 30 - 60 mL/hour in adults), so this does not indicate target organ damage from hypertension.
• Retinal blood vessel damage: Hypertension can cause damage to the blood vessels in the retina (a target organ). Changes in retinal blood vessels are a sign of hypertensive retinopathy, which is evidence of target organ damage.
• Blood urea nitrogen (BUN) concentration of 12 mg/dL: The normal range for BUN is approximately 7 - 20 mg/dL, so a BUN of 12 mg/dL is within the normal range and does not indicate target organ damage from hypertension.

Answer:

C. Retinal blood vessel damage
