health assessment practice questions

Correct Answer: D

Rationale: The correct answer is D. A shattered look to the light rays reflecting off the cornea indicates corneal abrasion. When the cornea is scratched or abraded, light rays reflecting off it appear shattered due to irregularities on the corneal surface. This is a classic sign of corneal abrasion. A: Smooth and clear corneas (incorrect) - This would not indicate corneal abrasion as abrasions cause irregularities on the corneal surface. B: Opacity of the lens behind the cornea (incorrect) - This suggests a different issue related to the lens, not corneal abrasion. C: Bleeding from the areas across the cornea (incorrect) - This suggests a more severe injury like a corneal laceration, not a simple abrasion. In summary, choice D is correct as the shattered look of light rays is a characteristic finding in corneal abrasion, while the other choices do not

Correct Answer: B

Rationale: The correct answer is B: Dehydration. Depressed and sunken fontanelles in an infant indicate dehydration due to decreased fluid volume. Dehydration causes a decrease in tissue turgor, leading to the fontanelles appearing sunken. Rickets (A) is a condition characterized by weak or soft bones due to vitamin D deficiency. Mental retardation (C) is a developmental disorder, not related to fontanelle appearance. Increased intracranial pressure (D) would cause bulging fontanelles, not depressed fontanelles. Therefore, the most likely condition in this case is dehydration.

Correct Answer: C

Rationale: The correct answer is C: Bell's palsy. Bell's palsy is characterized by sudden weakness or paralysis of the facial muscles, resulting in drooping of the face, inability to raise the eyebrow or close the eye, and difficulty with facial expressions and functions like whistling. In this case, the patient's symptoms of left-sided facial paralysis point towards Bell's palsy as the likely diagnosis. Cushing's syndrome (A) is a hormonal disorder, Parkinson's syndrome (B) is a neurodegenerative disorder affecting movement, and a cerebrovascular accident (D) typically presents with more generalized neurological deficits rather than isolated facial paralysis.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): 1. Red glow in pupils indicates a normal reflection off the inner retina known as the red reflex. 2. The red reflex helps to visualize the internal structures of the eye, including the retina. 3. This finding is expected during an ophthalmoscopic examination. 4. No abnormality is suggested by the presence of a red glow in the pupils. Summary of Other Choices: A: Incorrect. Red glow does not indicate an opacity in the lens or cornea. B: Incorrect. Checking the light source is unnecessary as red glow is a normal finding. D: Incorrect. Referral is not needed as red reflex is a normal part of an ophthalmoscopic exam.

Correct Answer: B

Rationale: The correct answer is B: This is a bifid uvula, which is a common occurrence in some Aboriginal groups. 1. A bifid uvula is a condition where the uvula is split or divided, which is a common variation seen in some Aboriginal populations. 2. Cleft palate is a different condition involving a gap in the roof of the mouth, not specifically related to Aboriginal people. 3. Uvular injury is not a common cause of a split uvula in children, so reporting to authorities is unnecessary. 4. Torus palatinus is a bony growth on the roof of the mouth and not related to a split uvula or specific to Aboriginal populations.
