The nurse observes erythema under the chin of a client receiving oxygen at 2 L/minute per nasal cannula. Which intervention should the nurse implement?

A. Ensure that the infant's crib mattress is firm. A firm mattress reduces the risk of SIDS by preventing the infant from sinking into a soft surface, which can obstruct breathing.

B. Prop the infant with a pillow when in a side-lying position. Propping with a pillow is not recommended as it can increase the risk of suffocation and is not a recommended SIDS prevention measure.
C. Place the infant in a prone position whenever possible. Placing an infant in a prone (stomach) position is a significant risk factor for SIDS. Infants should be placed on their backs to sleep.
D. Swaddle the infant in a blanket for sleeping. While swaddling can be safe if done correctly, it is not as critical as ensuring a firm mattress. Additionally, improper swaddling can pose risks if the blanket becomes loose.

A. Administer oxygen 5 L/minute via simple face mask: Oxygen administration is a priority intervention to improve oxygenation and address the client's low oxygen saturation of 82%.
Hypoxemia can lead to tissue hypoxia and further compromise the client's condition. Therefore, administering oxygen should be the first action taken to ensure an adequate oxygen supply to vital organs.
B. Bacitracin applied topically to lacerations every 12 hours: While wound care is important, administering oxygen and establishing IV access take precedence over topical
treatment. Oxygenation and fluid resuscitation are critical in the immediate management of a trauma patient to ensure adequate tissue perfusion and oxygen delivery.

C. Place 2 large bore peripheral IV's: Establishing IV access is essential for administering medications and fluids rapidly. This is particularly important in this scenario where the client may require immediate fluid resuscitation due to hypotension (blood pressure of 83/41 mm Hg).
Large bore IV access allows for rapid infusion of fluids and medications to stabilize the client's hemodynamic status.

D. X-ray of the right arm and cervical spine: While diagnostic imaging is important for assessing injuries, it is not as urgent as administering oxygen and establishing IV access. Oxygenation and fluid resuscitation are higher priorities to stabilize the client's condition before proceeding with diagnostic tests.

E. Computed tomography scan of the brain: While a CT scan of the brain is essential for assessing potential head injuries, the immediate focus should be on stabilizing the client's oxygenation and hemodynamic status. Administering oxygen and fluids take precedence over diagnostic imaging to address the client's hypoxemia and hypotension.

F. Vital signs every 1 hour: Monitoring vital signs is important for ongoing assessment, but it is not as urgent as administering oxygen and fluids. Vital signs should be monitored closely, but immediate interventions to address hypoxemia and hypovolemia are critical to stabilize the client's condition.

G. Give 1 Liter bolus of 0.9% sodium chloride solution IV once: The client's hypotension (blood pressure of 83/41 mm Hg) indicates hypovolemia and the need for fluid resuscitation. Administering a bolus of intravenous fluids (1 Liter bolus of 0.9% sodium chloride solution) is essential to address hypovolemia and improve perfusion to vital organs. This intervention helps stabilize the client's blood pressure and prevent further deterioration of her condition.
