health assessment practice questions Questions
Question 1 of 5
A patient has a normal pupillary light reflex. The nurse recognizes this to indicate that:
Correct Answer: D
Rationale: The correct answer is D because a normal pupillary light reflex involves the constriction of both pupils in response to bright light. This reflex is controlled by the autonomic nervous system, specifically the parasympathetic nervous system. When light is detected by the retina, signals are sent to the brain which then triggers the constriction of both pupils to reduce the amount of light entering the eye. Choices A, B, and C are incorrect because they do not accurately describe the pupillary light reflex. Vision convergence, light reflection, and focusing the image at the center of the pupil are not directly related to the pupillary light reflex.
Question 2 of 5
A patient's vision is recorded as 20/80 in each eye. The nurse recognizes that this finding indicates:
Correct Answer: A
Rationale: The correct answer is A: poor vision. In the 20/80 visual acuity notation, 20 represents the test distance in feet, and 80 represents the line on the eye chart that the patient can read. Therefore, a person with 20/80 vision can only see at 20 feet what a person with normal vision can see at 80 feet. This indicates poor vision as the patient's visual acuity is significantly below normal. Summary: - Choice B (acute vision) is incorrect as 20/80 vision indicates poor vision, not exceptional sharpness. - Choice C (normal vision) is incorrect as 20/80 vision is below normal range. - Choice D (presbyopia) is incorrect as presbyopia is a condition related to aging and difficulty focusing on close objects, not specifically indicated by 20/80 vision.
Question 3 of 5
A 60-year-old man is at the clinic for an eye examination. The nurse suspects that he has ptosis of one eye. Ptosis is:
Correct Answer: C
Rationale: The correct answer is C: drooping of the upper eyelid. Ptosis refers to the drooping of the upper eyelid, which may occur due to weakened eyelid muscles or nerve damage. In this case, the nurse suspects ptosis in the 60-year-old man, which is likely due to age-related muscle weakness. Choice A, a cloudy cornea, is incorrect as it refers to a different eye condition. Choice B, an unequal red reflex, is incorrect as it is related to abnormalities in the retina. Choice D, protruding and bulging eyes, is incorrect as it indicates exophthalmos, a condition typically seen in thyroid eye disease.
Question 4 of 5
In using the ophthalmoscope to assess a patient's eyes, the nurse notes a red glow in the patient's pupils. On the basis of this finding, the nurse would:
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.
Question 5 of 5
The nurse is conducting an eye clinic at the day care centre. When examining a 2-year-old child, if"lazy eye" is suspected, the nurse would:
Correct Answer: D
Rationale: The correct answer is D because testing for strabismus by performing the corneal light reflex test is crucial in diagnosing "lazy eye" or amblyopia in children. Strabismus is a condition where the eyes are misaligned, leading to poor vision in one eye. By performing the corneal light reflex test, the nurse can assess if the child's eyes are aligned or if there is deviation, which could indicate lazy eye. Options A, B, and C are incorrect as they do not specifically address the assessment of strabismus, which is the key indicator for lazy eye in this scenario.
