A nurse needs to administer 600 mg of a medication. The available supply is 200 mg per tablet. Using dimensional analysis, how many tablets should the nurse administer?

A. Patient reports feelings of loneliness:These social concerns belong to the love and belonging tier of the hierarchy. While significant for long-term psychological health, they do not pose an immediate threat to physical survival. They are addressed only after physiological and safety needs are stabilized.

B. Patient's elevated anxiety about diagnosis:Anxiety is a psychological response that falls under the categories of safety or self-esteem. Though it can impact physiological parameters, it is not the primary life-threatening priority in an acute clinical setting. Psychological stabilization follows the resolution of urgent biological deficits.

C. Low blood oxygen saturation levels:Oxygenation is a fundamental physiological requirement located at the base of the hierarchy. Hypoxemia can lead to rapid organ failure, cardiac arrest, and cellular death within minutes. It must be corrected before any higher-level psychosocial or emotional needs are considered.

D. A history of depression:Chronic psychiatric conditions represent long-term health management challenges rather than acute physiological crises. While important for holistic care, a stable history of depression does not supersede the immediate need for respiratory or circulatory support. It is prioritized lower than acute survival needs.

A. Increase supplemental oxygen and reassess the patient:Restlessness and confusion are classic early clinical manifestations of cerebral hypoxia. Increasing the fraction of inspired oxygen immediately addresses the physiological deficit at the base of Maslow's hierarchy. Reassessment ensures the intervention is effective in improving oxygen saturation and mental status.

B. Apply restraints for patient safety due to restlessness:Restraints are a last resort and are contraindicated if the patient's behavior is caused by a treatable physiological crisis like hypoxia. Restricting movement can increase agitation and further increase oxygen demand. The priority must be treating the underlying cause of the restlessness.

C. Notify the family about the change in mental status:Informing the family is a communication task that follows immediate clinical intervention. It does not address the life-threatening lack of oxygen that is causing the confusion. The patient's physical stability must be managed before administrative or family communication occurs.

D. Document the findings and observe for further deterioration:Passive observation in the presence of early hypoxia allows the patient's condition to worsen into respiratory arrest. Documentation is a legal requirement but should never delay active nursing intervention for an acute physiological change. Immediate action is required to prevent further decline.
