Three body systems work at different speeds to keep the pH in the narrow range of normal, The order of effectiveness for these three systems is:

kidneys, lungs, blood/chemical buffers

chemical buffers, kidneys, lungs

lungs, kidneys, and blood/chemical buffers

blood/chemical buffers, lungs, kidneys

Answer and Explanation

The Correct Answer is D

Rationale:
A. Kidneys are the slowest to respond, so this order is incorrect.
B. Kidneys are slower than lungs, so this order is incorrect.
C. Lungs respond faster than kidneys but slower than chemical buffers, so this order is incorrect.
D. Chemical buffers act immediately to neutralize pH changes (first line), lungs adjust CO₂ levels within minutes (second line), and kidneys regulate acid-base balance over hours to days (third line), making this the correct order.

Correct Answer is D

Explanation

Rationale:
A. Respiratory alkalosis results from hyperventilation, which is unlikely with opioid overdose.
B. Metabolic acidosis can occur from other causes but is not the primary imbalance here.
C. Metabolic alkalosis is not associated with opioid overdose.
D. Respiratory acidosis occurs due to hypoventilation caused by opioid-induced respiratory depression, leading to CO₂ retention and decreased pH.

A. PH B. PaCO2 C. HCO3 D. PaO2 E. blood glucose

Correct Answer is ["A","B","C","D"]

Explanation

Rationale:
A. pH indicates the overall acid-base status (acidosis or alkalosis) and is critical in determining the presence of an imbalance.
B. PaCO₂ reflects the respiratory component of acid-base balance and helps assess respiratory acidosis or alkalosis.
C. HCO₃ (bicarbonate) reflects the metabolic component of acid-base balance and is essential for evaluating metabolic acidosis or alkalosis.
D. PaO₂ indicates the oxygenation status of the client, which is important in assessing respiratory function, though not a direct marker of acid-base imbalance.
E. Blood glucose is not part of arterial blood gas analysis and is unrelated to acid-base balance interpretation.
