A nurse is caring for a client who has metabolic acidosis. Which of the following could be a cause for the for metabolic acidosis?
Breast cancer
Parathyroidectomy
Use of salicylates
Rhabdomyolysis
The Correct Answer is C
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.

Correct Answer is B
Explanation
A. HCO3 above 26 mEq/L: This would indicate metabolic alkalosis, not metabolic acidosis.
B. pH below 7.35: Metabolic acidosis is characterized by a low pH (<7.35) due to excess acid accumulation or bicarbonate loss.
C. PaCO2 above 45 mm Hg: PaCO2 above 45 mm Hg is seen in respiratory acidosis, not metabolic acidosis.
D. PaO2 below 70 mm Hg: A low PaO2 indicates hypoxemia, which can occur alongside acidosis but is not a defining feature of metabolic acidosis.
Correct Answer is ["B","D"]
Explanation
A. Diarrhea: TCAs cause anticholinergic effects, which more commonly lead to constipation rather than diarrhea.
B. Weight gain/loss: Weight gain is a common side effect of TCAs, though some clients may experience weight loss.
C. Bradycardia: TCAs are more likely to cause tachycardia, arrhythmias, and orthostatic hypotension, not bradycardia.
D. Sexual dysfunction: TCAs can cause sexual dysfunction, including decreased libido, erectile dysfunction, and anorgasmia.
