What signs and symptoms indicate hypoxia? Select all that apply.
Alert and oriented
Cyanosis
Anxiety and restlessness
Oxygen saturation 96%
Capillary refill 5 seconds
Correct Answer : B,C,E
A) Alert and oriented: Being alert and oriented typically indicates adequate oxygenation, not hypoxia. Patients experiencing hypoxia are more likely to show signs of confusion or altered mental status rather than clarity.
B) Cyanosis: Cyanosis is a classic sign of hypoxia, presenting as a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood. This is a significant indicator of inadequate oxygenation.
C) Anxiety and restlessness: These symptoms are common responses to hypoxia as the body attempts to compensate for insufficient oxygen. Patients may feel anxious or restless as they struggle to breathe or feel a sense of impending doom.
D) Oxygen saturation 96%: An oxygen saturation level of 96% is generally considered normal and indicates adequate oxygenation. Therefore, this finding does not suggest hypoxia.
E) Capillary refill 5 seconds: A prolonged capillary refill time can indicate poor perfusion and potential hypoxia. Inadequate blood flow can lead to reduced oxygen delivery to tissues, making this a relevant sign of hypoxia

Correct Answer is C
Explanation
A) Talking in a loud voice: While this may indicate some level of distress or confusion, it does not necessarily signal a specific neurological deficit. Clients may raise their voice for various reasons unrelated to neurological issues.
B) Grimacing with movement: This could suggest discomfort or pain but is not an explicit indicator of neurological impairment. Grimacing can occur for many reasons, including musculoskeletal issues or emotional responses, and does not specifically necessitate a focused neurological assessment.
C) Asymmetry of the client's smile: This finding is significant and raises concerns about potential neurological issues, such as a stroke or Bell's palsy. Facial asymmetry may indicate weakness or dysfunction in the cranial nerves responsible for facial movement, warranting a more thorough neurological examination to assess for underlying causes.
D) Inability to follow directions: While this may point to confusion or cognitive impairment, it is a more general indicator and could result from various factors, including anxiety or lack of understanding. It does not specifically highlight a localized neurological deficit as clearly as facial asymmetry does.
Correct Answer is D
Explanation
A) Inflammation of the lamina of the involved vertebra: While inflammation can contribute to pain, it is not the primary cause in the context of a herniated disc. The pain associated with a herniated disc is typically related to nerve compression rather than inflammation of the lamina itself.
B) Shifting of two adjacent vertebrae out of alignment: This describes a different condition, such as spondylolisthesis. A herniated disc primarily involves the displacement of disc material, rather than a significant misalignment of the vertebrae.
C) Increased pressure of cerebral spinal fluid within the vertebral column: Increased cerebrospinal fluid pressure is not typically associated with herniated discs and does not directly cause the pain related to this condition.
D) Compression of the spinal cord by the extruding disc: This is the most accurate explanation for the patient's pain. A cervical herniated disc can protrude and compress nearby nerve roots or the spinal cord itself, leading to significant pain, weakness, and other neurological symptoms. This compression is the primary cause of pain in patients with this diagnosis.
