The nurse provides care to a patient admitted with a respiratory disorder. Which laboratory finding is most concerning?
Oxygen saturation 96%
Blood pH 7.32
Hemoglobin level 12 mg/dL
PaO2 80 mm Hg
The Correct Answer is B
A. Oxygen saturation 96%. This is a normal oxygen saturation level, so it is not a concern.
B. Blood pH 7.32. A pH below 7.35 indicates acidosis, which is concerning in a patient with a respiratory disorder, as it may indicate respiratory failure.
C. Hemoglobin level 12 mg/dL. This is a normal hemoglobin level for most adults and does not indicate a critical problem.
D. PaO2 80 mm Hg. While slightly lower than the normal range (normal is 80–100 mm Hg), this is not the most concerning finding.

Correct Answer is B
Explanation
A. Headache: While headaches can occur, they are not the most concerning side effect of stimulant medications.
B. Tachycardia: Stimulant medications, such as those used to treat ADHD (e.g., methylphenidate, amphetamines), increase central nervous system activity, which can lead to an increased heart rate (tachycardia).
C. Dizziness: While dizziness can occur, it is not the primary concern with stimulants.
D. Dry mouth: Dry mouth is a possible side effect but is not as clinically significant as tachycardia when monitoring for adverse effects.
Correct Answer is D
Explanation
A. The client has a pleasant affect: "Affect" refers to outward emotional expression, whereas "mood" is the client's internal emotional state.
B. The client appears happy with an elevated mood: The nurse should document objective data rather than interpreting the client’s emotions.
C. The client self-isolated today: While self-isolation may indicate mood disturbances, it does not directly document the client’s reported mood.
D. The client rates their mood 4 out of 10: This entry reflects the client’s subjective report using a measurable scale, making it the most accurate documentation.
