health assessment practice questions Questions
Question 1 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.
Question 2 of 5
A patient comes into the emergency department after an accident at work. He had not been wearing safety glasses, and a machine had blown dust into his eyes. The nurse examines his corneas by shining a light from the side across the cornea. What findings would suggest that he has suffered corneal abrasion?
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
Question 3 of 5
During an assessment, a patient says that she was diagnosed with open-angle glaucoma 2 years ago. There are various types of glaucoma, such as open-angle glaucoma and closed-angle glaucoma. Which of the following are characteristics of open-angle glaucoma? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B: It is the most common type of glaucoma. Open-angle glaucoma is indeed the most common type, accounting for about 90% of all glaucoma cases. In open-angle glaucoma, the drainage angle of the eye remains open, but the trabecular meshwork becomes blocked over time. This leads to increased intraocular pressure, which can damage the optic nerve and result in vision loss. A, C, and D are incorrect: A: The symptoms mentioned (sensitivity to light, nausea, halos around lights) are more commonly associated with acute angle-closure glaucoma, not open-angle glaucoma. C: Immediate treatment is not necessarily needed for open-angle glaucoma as it progresses slowly, and treatment can vary based on the severity of the condition. D: Vision loss in open-angle glaucoma typically starts with the loss of peripheral vision, not central vision.
Question 4 of 5
Which of the following statements about the eustachian tube is true?
Correct Answer: D
Rationale: The correct answer is D: It helps equalize air pressure on both sides of the tympanic membrane. The eustachian tube connects the middle ear to the nasopharynx, allowing for pressure equalization. During activities like swallowing or yawning, the tube opens to allow air to flow in or out, maintaining equal pressure. This function is crucial for proper hearing and preventing discomfort or damage to the tympanic membrane. Choice A is incorrect as cerumen is produced by ceruminous glands in the ear canal, not the eustachian tube. Choice B is incorrect as the eustachian tube normally remains closed and opens only intermittently during specific actions. Choice C is incorrect as the eustachian tube does not connect the middle and outer ear; it connects the middle ear to the nasopharynx.
Question 5 of 5
Tests have shown that a patient has sensorineural hearing loss. During the assessment, it would be important for the nurse to:
Correct Answer: B
Rationale: The correct answer is B: assess for middle ear infection as a possible cause. Sensorineural hearing loss is usually caused by damage to the inner ear or the nerve pathway to the brain. Middle ear infection can sometimes lead to conductive hearing loss, but it's important to rule out this possibility during assessment. Speaking loudly (A) is not effective for sensorineural hearing loss. Asking about medications (C) may be relevant but not as crucial as assessing for a possible cause. Looking for external ear obstruction (D) is more relevant for conductive hearing loss, not sensorineural.
