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 C
Explanation
A. Hypertension: Blood loss leads to hypovolemia, which usually causes hypotension, not hypertension.
B. Hypothermia: While hypothermia can occur postoperatively, it is not the most direct result of blood loss.
C. Tachycardia: Blood loss leads to decreased circulating volume, triggering tachycardia as a compensatory response to maintain oxygen delivery.
D. Bradypnea: Severe blood loss is more likely to cause tachypnea (rapid breathing) rather than slow respirations.
Correct Answer is B
Explanation
A. Restricts the client's ability to eat, speak, or drink: Unlike a mask, a nasal cannula allows the client to eat, drink, and speak freely.
B. Delivers a low concentration of oxygen: A nasal cannula delivers a low oxygen concentration (24%-44%) at flow rates of 1-6 L/min.
C. Delivers a constant rate of a specific concentration of oxygen: Oxygen concentration varies depending on the client's breathing pattern with a nasal cannula, making it not a fixed concentration delivery system.
D. Delivers a high concentration of oxygen: High-flow oxygen delivery systems like a non-rebreather mask or Venturi mask are needed for high oxygen concentrations.
