Name the following arterial blood gas (ABG) values: pH 7.47, PaCO2 32, HCO3- 23

Respiratory Acidosis

Metabolic Acidosis

Metabolic Alkalosis

Respiratory Alkalosis

Answer and Explanation

The Correct Answer is D

Choice A reason: Respiratory acidosis has low pH and high PaCO2. High pH (7.47) and low PaCO2 (32) indicate alkalosis, not acidosis, so this incorrect.

Choice B reason: Metabolic acidosis has low pH and HCO3-. High pH and normal HCO3- (23) rule this out, pointing to respiratory alkalosis, so this is incorrect.

Choice C reason: Metabolic alkalosis has high pH and high HCO3-.. Normal HCO3- and low PaCO2 indicate respiratory alkalosis, so this is incorrect.

Choice D reason: High pH (7.47) and low PaCO2 (32) with normal CO2 HCO3- confirm respiratory alkalosis due to hyperventilation. This is matches, so it’s correct.

Correct Answer is D

Explanation

Choice A reason: Metabolic acidosis has low pH and HCO3-. Normal pH (7.41) and high HCO3- (30) suggest alkalosis, not acidosis, so this is incorrect for the ABG values.

Choice B reason: Respiratory acidosis has high PaCO2 and low pH. Normal pH and high HCO3- indicate metabolic alkalosis, not respiratory acidosis, so this is incorrect.

Choice C reason: Respiratory alkalosis has low PaCO2 and high pH. High PaCO2 (46) and HCO3- rule this out, pointing to metabolic alkalosis, so this is incorrect.

Choice D reason: Normal pH (7.41), high PaCO2 (46), and high HCO3- (30) indicate metabolic alkalosis fully compensated by respiratory CO2 retention. This is correct.

A. The fetus must be monitored closely while the patient is taking this drug. B. The patient’s prescriber probably will change her medication to an ARB. C. The patient should stop taking the medication and contact her provider immediately. D. Assuming continue the medication with dose adjustment.

Correct Answer is C

Explanation

Choice A reason: ACE inhibitors are teratogenic, risking fetal harm, so monitoring while continuing is unsafe. Stopping the drug is critical, making this incorrect for safe pregnancy management.

Choice B reason: ARBs are also contraindicated in pregnancy due to similar teratogenic risks. Switching to an ARB is not safe, so this is incorrect compared to stopping the medication.

Choice C reason: ACE inhibitors can cause fetal abnormalities, so the patient must stop the medication and contact her provider immediately for safer alternatives. This is the correct action.

Choice D reason: Continuing ACE inhibitors, even adjusted, is dangerous in pregnancy due to teratogenicity. Immediate cessation and provider consultation are required, making this incorrect.
