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?
Metabolic alkalosis
Metabolic acidosis
Respiratory alkalosis
Respiratory acidosis
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 B
Explanation
A. Observing for facial symmetry assesses cranial nerves VII (facial nerve), not cranial nerve III.
B. Cranial nerve III (oculomotor nerve) is responsible for eye movement and pupillary response, making checking the pupillary response to light the correct action.
C. Testing visual acuity primarily assesses cranial nerve II (optic nerve), not cranial nerve III.
D. Eliciting the gag reflex is associated with cranial nerves IX (glossopharyngeal) and X (vagus), not cranial nerve III.
Correct Answer is A
Explanation
A. Having the child bend at the waist allows the nurse to observe the spine for any abnormal curvature indicative of scoliosis, such as uneven shoulders or a rib hump.
B. Measuring the distance between the knees and the ankles is not a technique used to screen for scoliosis; it is more related to assessing leg length discrepancies.
C. Measuring the length of each leg does not assess for scoliosis but is more relevant for evaluating leg length inequalities.
D. Asking the child to walk across the room is useful for assessing gait and balance but does not directly assess for scoliosis.
