4 Clinical Manifestations and Treatment Priorities Free Online FlashCards

What takes priority over an abnormal ABG value?

Stabilize airway, breathing, circulation, and mental status before treating an ABG value.

Which clinical changes warrant urgent escalation?

Confusion, drowsiness, exhaustion, hypotension, dysrhythmia, and worsening hypoxemia call for urgent escalation and close monitoring.

What sequence helps interpret an ABG?

Identify the pH direction, then determine whether PaCO₂ or HCO₃⁻ best explains it. Check whether compensation is appropriate.

Why assess oxygenation separately from pH?

Assess oxygenation separately; pH alone does not show whether oxygen delivery or ventilation is adequate.

In the DKA scenario, is PaCO₂ of $18$ mmHg appropriate compensation?

A very low HCO₃⁻ with acidemia indicates metabolic acidosis. With HCO₃⁻ of $6$ mEq/L, Winter’s formula predicts PaCO₂ near $17 \pm 2$ mmHg, so $18$ mmHg is appropriate compensation.

Does high serum potassium rule out potassium depletion in DKA?

A high serum potassium does not rule out total-body potassium depletion.

What electrolyte needs particular attention during DKA insulin treatment?

Pay particular attention to potassium before and during insulin therapy, and follow glucose and electrolytes as directed.

When is bicarbonate generally considered in adult DKA?

Bicarbonate is not routine DKA treatment; consideration is generally reserved for extreme acidemia, with pH below $7.0$.

What does worsening ventilation with drowsiness suggest in COPD?

A falling pH with rising PaCO₂ in a patient with chronic CO₂ retention suggests acute worsening of respiratory acidosis. Drowsiness and increased work of breathing raise concern for ventilatory failure.

What oxygen saturation target is commonly used for patients at risk of hypercapnic respiratory failure?

For patients at risk of hypercapnic respiratory failure, oxygen is commonly titrated to $88\text{–}92\%$ while blood gases are being assessed.

What airway-related concern affects escalation in ventilatory failure?

Assess whether noninvasive ventilation is suitable and escalate if the patient deteriorates or cannot protect the airway.

Why is metabolic alkalosis with hypokalemia and palpitations urgent?

Metabolic alkalosis with severe hypokalemia, palpitations, and an abnormal ECG signals immediate dysrhythmia risk; prioritize cardiac monitoring.
