What age group should be routinely screened for scoliosis?
Newborn
Young teens
Older adult
None of the above
The Correct Answer is B
Choice A reason: Newborns are not routinely screened for scoliosis, as it typically develops later. Congenital scoliosis may be assessed in infants with specific risk factors, but routine screening occurs in adolescence when idiopathic scoliosis emerges, making this choice incorrect.
Choice B reason: Young teens, particularly ages 10–15, are routinely screened for scoliosis, as idiopathic scoliosis commonly appears during the growth spurt of puberty. Early detection via physical exams allows for interventions like bracing to prevent curve progression, making this the correct choice.
Choice C reason: Older adults are not routinely screened for scoliosis, as most cases are degenerative or pre-existing. Screening focuses on adolescents when curves are most likely to develop. In adults, scoliosis is monitored if symptomatic, making this choice incorrect.
Choice D reason: Routine scoliosis screening is recommended for young teens, not none of the above. Guidelines from organizations like the American Academy of Pediatrics emphasize screening during adolescence to catch idiopathic scoliosis early, making this choice incorrect.

Correct Answer is A
Explanation
Choice A reason: A nasal cannula delivers low-flow oxygen (2-6 L/min, 24-44% FiO2), suitable for patients needing minimal supplemental oxygen. It provides low concentrations to maintain adequate oxygenation without precise control, ideal for stable patients with mild hypoxemia, like those with chronic lung conditions.
Choice B reason: A nasal cannula does not deliver a constant rate of specific oxygen concentration. Unlike Venturi masks, it provides variable FiO2 based on the patient’s breathing pattern, making this statement incorrect for describing the cannula’s low-flow, non-precise oxygen delivery.
Choice C reason: A nasal cannula does not significantly restrict eating, speaking, or drinking, as it sits below the nose, allowing oral functions. This contrasts with masks that cover the mouth, making this statement incorrect for the cannula’s minimally invasive design.
Choice D reason: A nasal cannula does not deliver high-concentration oxygen, which requires devices like nonrebreather masks (up to 90-100% FiO2). Its low-flow delivery (24-44% FiO2) is insufficient for high oxygen needs, making this choice incorrect for its capabilities.
Correct Answer is B
Explanation
Choice A reason: Continuing suctioning during decreased oxygen saturation and bradycardia worsens hypoxia, as suctioning removes oxygen from the airway. Administering 50% oxygen is insufficient to rapidly correct severe desaturation, making this action inappropriate compared to stopping suctioning and providing 100% oxygen.
Choice B reason: Discontinuing suctioning prevents further oxygen depletion, as suctioning removes air from the airway, exacerbating hypoxia. Administering 100% oxygen rapidly restores oxygen saturation, addressing bradycardia caused by hypoxemia. This aligns with critical care protocols, making it the best action.
Choice C reason: Preparing for resuscitation is premature unless the patient is unresponsive or in cardiac arrest. Decreased oxygen saturation and bradycardia can often be reversed by stopping suctioning and providing oxygen, making this action less immediate than addressing hypoxia directly.
Choice D reason: Continuing suctioning worsens hypoxia, and epinephrine is not indicated for bradycardia caused by suctioning-related hypoxemia. Epinephrine is used in cardiac arrest or allergic reactions, not routine suctioning complications, making this choice incorrect for the scenario.
