A nurse is caring for a client who has lung cancer and has a sealed radiation implant. Which of the following actions should the nurse take? (Select all that apply)

Choice A reason: Performing postural drainage immediately after meals risks aspiration and discomfort due to gastric contents shifting during positioning. It should be done 1-2 hours after meals to ensure safety and efficacy in clearing mucus from the lungs, making this timing inappropriate for cystic fibrosis management.
Choice B reason: Performing postural drainage twice daily is recommended for cystic fibrosis to mobilize thick mucus from the lungs, improving airway clearance and reducing infection risk. This frequency balances effectiveness with patient tolerance, aligning with evidence-based guidelines for managing chronic respiratory conditions, making it the correct action.
Choice C reason: Using a percussion vest is an alternative to manual postural drainage but is not specified as the only method. Manual techniques are effective and standard unless a vest is prescribed. This choice assumes equipment availability, which may not apply, making it less universally appropriate than scheduled manual drainage.
Choice D reason: Positioning the child flat during postural drainage is incorrect, as specific angled positions (e.g., head-down) are needed to target lung segments and promote mucus drainage by gravity. Flat positioning reduces effectiveness and may not clear airways adequately, making this an inappropriate technique for cystic fibrosis.

Choice A reason: Increased energy and motivation signal improvement in major depressive disorder, countering fatigue and anhedonia. Serotonin and norepinephrine rebalance, often from treatment, restores drive and engagement, reflecting neurochemical stabilization in the brain’s limbic system, critical for mood regulation and recovery.
Choice B reason: Self-doubt in decision-making reflects persistent depressive symptoms, like low self-esteem and cognitive impairment. Negative thought patterns, driven by altered prefrontal cortex activity, indicate ongoing depression, not improvement, requiring adjusted interventions to address these neurocognitive deficits in major depressive disorder.
Choice C reason: Sleeping 12 hours daily indicates hypersomnia, a depressive symptom, suggesting no improvement. Disrupted circadian rhythms and serotonin dysregulation cause excessive sleep, contrasting with recovery signs like normalized sleep patterns. This reflects persistent neurochemical imbalances hindering mood stabilization in depression.
Choice D reason: Social isolation is a core depressive symptom, driven by anhedonia and low mood, indicating no improvement. Withdrawal reflects ongoing dopamine and serotonin imbalances, preventing social engagement. Recovery involves increased interaction, making isolation a sign of persistent major depressive disorder.
