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

Answer and Explanation

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 C

Explanation

A. Breast cancer: Breast cancer itself does not cause metabolic acidosis. However, in rare cases, tumor lysis syndrome from aggressive cancer treatment can lead to metabolic acidosis due to increased release of intracellular acids.

B. Parathyroidectomy: Removal of the parathyroid glands can cause hypocalcemia, but it does not directly lead to metabolic acidosis.

C. Use of salicylates: Salicylate toxicity (aspirin overdose) can cause metabolic acidosis due to the accumulation of lactic acid and ketoacids.

D. Rhabdomyolysis: Rhabdomyolysis causes metabolic acidosis due to the breakdown of muscle tissue, leading to the release of myoglobin, potassium, and acids into the bloodstream.

A. The client has a pleasant affect B. The client appears happy with an elevated mood C. The client self-isolated today D. The client rate their mood 4 out of 10

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.
