A patient has a normal corneal light reflex. The nurse recognizes that this reflex indicates which information about the eyes?

The eyes converge and the pupils constrict to focus on the light.

The constriction of both pupils occurs in response to bright light.

The eyes focus the image in the center of the macula for precise vision.

The eyes are normally aligned when the light is in the same location on each eye.

Answer and Explanation

The Correct Answer is D

Choice A reason: Convergence and pupil constriction are accommodation reflexes, not corneal light reflex, which tests alignment. Light reflection symmetry indicates eye alignment, so this incorrect for the reflex’s purpose.

Choice B reason: Pupil constriction is a pupillary reflex, not corneal light reflex. The corneal reflex involves light reflection on corneas, assessing alignment, not pupil response, so this is incorrect.

Choice C reason: Macular focus is related to visual acuity, not corneal reflex, light reflex, which checks eye alignment via light reflection. Symmetric reflection is key, so this incorrect for the reflex’s indication.

Choice D reason: A normal corneal reflex shows light reflecting in the same spot on both corneas, indicating proper eye alignment. This is the definition of the reflex, making it the correct choice for eye assessment.

Correct Answer is A

Explanation

Choice A reason: The human spinal column has 33 vertebrae: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral (fused), and 4 coccygeal (fused). The 5 lumbar vertebrae, located in the lower back, support significant weight and allow flexibility, making this choice correct for the vertebral count.

Choice B reason: The cervical spine consists of 7 vertebrae, not 12, which are designed for mobility and support of the head. The incorrect count of 12 aligns with the thoracic vertebrae, making this choice scientifically inaccurate for the cervical region.

Choice C reason: The sacral region has 5 vertebrae, which fuse into the sacrum in adults, not 7. The sacrum forms part of the pelvis, providing stability. The incorrect count of 7 corresponds to the cervical vertebrae, making this choice incorrect.

Choice D reason: The thoracic spine comprises 12 vertebrae, not 5, which articulate with the ribs to form the thoracic cage. The incorrect count of 5 aligns with the lumbar or sacral vertebrae, rendering this choice inaccurate for the thoracic region.

A. Use the Brief Pain Inventory to assess the patient’s pain B. Observe the patient’s body language for pacing and agitation C. Note whether the patient is calling out, groaning, or crying D. Assess the patient’s breathing independent of vocalization E. Have the patient rate pain on a 1-to-10 scale

Correct Answer is ["B","C","D"]

Explanation

Choice A reason: The Brief Pain Inventory relies on verbal or cognitive input, which is unreliable in advanced dementia due to impaired communication and cognition. Patients may not articulate pain, making this tool ineffective for assessing pain in this population.

Choice B reason: Observing body language, like pacing or agitation, is a valid pain indicator in advanced dementia. These nonverbal behaviors reflect discomfort processed by intact pain pathways, despite cognitive decline, making this a reliable assessment method.

Choice C reason: Noting vocalizations like groaning or crying is effective, as these are instinctive responses to pain, even in advanced dementia. These behaviors bypass cognitive deficits, reflecting pain perception in the brain’s nociceptive pathways, making this a correct choice.

Choice D reason: Assessing breathing changes, like rapid or irregular patterns, is a reliable nonverbal pain indicator in dementia. Pain can stimulate the autonomic nervous system, altering respiration independently of vocalization, making this a valid assessment technique.

Choice E reason: A 1-to-10 pain scale requires cognitive ability to quantify and communicate pain, which is impaired in advanced dementia. This method is unreliable, as patients cannot reliably report, making it an incorrect choice for this population.
