What is the priority nursing action for status asthmaticus?

First minutes: oxygen and a bronchodilator together

Status asthmaticus is a severe attack that does not settle with the client's usual reliever. MSD Manuals calls the short-acting beta-2 agonist, such as albuterol, the cornerstone of treatment, given repeatedly in the first hour. Oxygen runs at the same time, aimed at keeping saturation above 90 percent. Neither needs to wait for the other.

Ipratropium may be added, and systemic corticosteroids are given for all but the mildest attacks. The steroid treats airway inflammation; it does not relieve the tight airways in the next few minutes the way the inhaled bronchodilator does. On a priority question, the inhaled reliever and oxygen come before the steroid, a chest x-ray or a full history.

The signs that the client is tiring

The most dangerous sign looks like improvement. A silent chest happens when so little air moves that wheezing fades. MSD Manuals lists altered consciousness, cyanosis, pulsus paradoxus over 15 mm Hg, saturation under 90 percent and a PaCO2 over 45 mm Hg as markers of a severe attack. Inability to finish a sentence fits the same picture.

Carbon dioxide is the value students misread. Early in an attack the client breathes fast and blows carbon dioxide off, so the level is low. MSD Manuals notes that a PaCO2 climbing above 40 mm Hg signals progression toward respiratory failure, and that altered mental status and fatigue are reasons to intubate. A normal number in a working, exhausted client is a warning, not reassurance.

Why sedation is the wrong comfort measure

Clients in a severe attack are frightened, and the stem may offer an anxiety medicine to calm them. MSD Manuals states that anxiolytics and morphine are relatively contraindicated in acute asthma because they depress breathing. The anxiety comes from low oxygen; treating the airway treats the fear.

Stay with the client, speak in short, calm instructions, and keep them sitting upright so the chest can expand. Avoid asking long questions that need long answers. NHLBI describes nebulized medicine, IV medicines, oxygen and sometimes a ventilator as the emergency treatments, so prepare the room for escalation rather than sending the client for tests.

Which finding should the nurse report first?

Report a change in mental status first: new drowsiness, confusion or difficulty staying awake. Report a quiet chest with continued effort, falling saturation despite oxygen, blue lips, and a carbon dioxide result that is normal or rising, as each points toward respiratory failure. NHLBI also lists symptoms that do not ease after reliever medicine as a reason for emergency care.

What can wait: peak flow testing in a client too breathless to talk, teaching about inhaler technique and triggers, and a review of the home action plan. Assistive staff can help with positioning and measure vital signs once the client is stable, but the nurse keeps the ongoing respiratory assessment. Link teaching to the asthma care plan after the crisis passes.

Hypothetical practice scenario

Hypothetical scenario, not a real exam item: a client in the emergency department with a severe asthma attack was wheezing loudly 30 minutes ago. Now the wheeze is barely heard, the client is drowsy, oxygen saturation is 88 percent on oxygen, and the arterial PaCO2 is 44 mm Hg. Which action comes first: give the ordered lorazepam for anxiety, document the improved wheeze, or notify the provider and prepare for intubation?

Notify the provider and prepare for intubation. Less wheeze with drowsiness and a normal-range PaCO2 in this setting means airflow has dropped and the client is tiring. Lorazepam would depress breathing further. Charting the quieter chest as improvement is the misreading the question is built on.
