The nurse reviews the arterial blood gas results of a client and notes the following:  

pH 7.45, [normal range: 7.35-7.45]  

Paco2 of 30 mm Hg (30 mmol/L), [normal range: 35-45]  

HCO3- of 20 mEq/L (20 mmol/L), [normal range: 22-26]  

Which condition would the nurse analyze these results to indicate?

A.

Metabolic alkalosis

B.

Metabolic acidosis

C.

Respiratory alkalosis

D.

Respiratory acidosis

Answer and Explanation

The Correct Answer is C

A. Metabolic alkalosis is characterized by a high pH and a high HCO3- level; this does not match the provided values.  

 

B. Metabolic acidosis would show a low pH and a low HCO3-, which does not match the findings.  

 

C. The pH is high (7.45) while the Paco2 is low (30 mm Hg), indicating respiratory alkalosis. The low HCO3- could be a compensatory mechanism but does not change the primary interpretation of respiratory alkalosis.  

 

D. Respiratory acidosis would be indicated by a low pH and a high Paco2, which is not the case here.

Correct Answer is C

Explanation

A. This would show a regular rhythm with a consistent rate (60-100 bpm) and clear P waves before each QRS complex, which is not present in asystole.

B. This indicates a slow heart rate (below 60 bpm) but would still display P waves and QRS complexes; asystole shows no electrical activity.

C. This is the correct interpretation as it represents a flatline on the ECG, indicating no electrical activity in the heart.

D. This would show a rapid heart rate (above 100 bpm) with present P waves, which is not the case in asystole.

Correct Answer is A

Explanation

A. Cranial nerve VII (facial nerve) is not primarily responsible for hearing; however, it does have some sensory function in the ear region. The primary cranial nerve responsible for hearing is cranial nerve VIII (vestibulocochlear), which is not listed among the options.

B. Cranial nerve X (vagus nerve) is primarily involved in autonomic functions and does not directly relate to hearing.

C. Cranial nerve I (olfactory nerve) is responsible for the sense of smell.

D. Cranial nerve II (optic nerve) is responsible for vision.
