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 B
Explanation
A) Have the client smile, frown, and puff out their cheeks: This test assesses the facial nerve (cranial nerve VII), not the trigeminal nerve (cranial nerve V). While important for evaluating facial movement, it does not specifically test the motor function of the trigeminal nerve, which is responsible for mastication.
B) Palpate the masseter muscles when the client clenches their teeth: This is the correct test for assessing the motor function of the trigeminal nerve. The trigeminal nerve innervates the muscles responsible for chewing, and palpating the masseter muscles during clenching allows the nurse to evaluate muscle strength and function. It provides insight into the motor capabilities associated with this cranial nerve.
C) Assess constriction of the client's pupils with direct and indirect light: This test evaluates the function of the optic nerve (cranial nerve II) and the oculomotor nerve (cranial nerve III). It does not assess the trigeminal nerve and is not relevant for this assessment.
D) Ask the patient to turn their head left and right with resistance: This action tests the spinal accessory nerve (cranial nerve XI), which is involved in neck movement. It does not relate to the function of the trigeminal nerve, making it an inappropriate choice for this specific assessment.
Correct Answer is C
Explanation
A) Obtain an order for a catheter: While catheterization can help manage elimination needs, it is generally considered a more invasive approach and is not the first line of action unless absolutely necessary. The goal should be to maintain the client’s dignity and encourage as much independence as safely possible.
B) Allow the client to walk independently: Given that the Romberg test is positive, indicating potential balance issues, allowing the client to walk independently could increase the risk of falls and injury. Safety is a primary concern in this situation.
C) Obtain a bedside commode: This intervention is appropriate as it provides a safe and accessible option for the client to meet their elimination needs without the need to navigate to a bathroom, which may be challenging given their balance issues. A bedside commode allows for easier access while minimizing the risk of falls.
D) Limit fluid intake: Limiting fluid intake is not a safe or effective way to address elimination needs and could lead to dehydration and other complications. Encouraging appropriate fluid intake is important for overall health, provided the client can manage elimination safely.
