A woman was brought to the emergency department of a hospital after she fell into the ground and hurt her left leg. She is noted to be tachycardic and tachypneic. Painkillers were carried out to lessen her pain. Suddenly, she started complaining that she is still in pain and now experiencing muscle cramps, tingling, and paraesthesia. Measurement of arterial blood gas reveals pH 7.6, PaO2 120 mm Hg. PaCO2 31 mm Hg, and HCO3 25 mmol/L.

What does this mean?

Respiratory Acidosis, Partially Compensated

Respiratory Alkalosis, Uncompensated

Metabolic Alkalosis. Uncompensated

Metabolic Alkalosis. Partially Compensated

Answer and Explanation

The Correct Answer is B

A.   This is incorrect because the pH is indicative of alkalosis, not acidosis, and the body has not compensated.
B.   The arterial blood gas (ABG) values provided indicate a pH of 7.6, which is above the normal range (7.35-7.45), suggesting alkalosis. The PaCO2 is low at 31 mm Hg, indicating hyperventilation, which is a respiratory process. Since the HCO3 is normal at 25 mmol/L, it suggests that the metabolic system is not the cause of the alkalosis. The body has not had time to compensate for the high pH with renal adjustments to the bicarbonate level, which would be seen in a partially compensated state.
C.   This is incorrect because the bicarbonate level is normal, suggesting the metabolic system is not the cause.
D.   This is incorrect because the bicarbonate level is normal, suggesting the metabolic system is not the cause.

Correct Answer is C

Explanation

A. Almonds are high in oxalates, which can contribute to the formation of calcium oxalate kidney stones. Therefore, almonds should be avoided or consumed in moderation by individuals with this condition.
B. Sweet potatoes contain moderate levels of oxalates, which may increase the risk of calcium oxalate kidney stones if consumed in large amounts. It is advisable for individuals with this condition to limit their intake of sweet potatoes.
C. Bananas are low in oxalates, making them a suitable choice for individuals with calcium oxalate kidney stones. Including bananas in the diet can help reduce the risk of stone formation.
D. Soy milk may contain moderate to high levels of oxalates, depending on processing methods. It is recommended to choose low-oxalate alternatives for individuals prone to calcium oxalate kidney stones.

A. pH 7.45 B. PaCO, 50 mm Hg C. Potassium 3.3 mEq/L D. HCO 30 mEq/L

Correct Answer is B

Explanation

A. In respiratory acidosis, the pH would be lower than normal due to an excess of carbon dioxide.
B. PaCO2 (partial pressure of carbon dioxide) would be elevated in respiratory acidosis because of inadequate ventilation leading to CO2 retention.
C. Potassium levels may vary depending on other factors but are not directly related to respiratory acidosis.
D. HCO3 (bicarbonate) levels may be normal or increased compensatorily in chronic respiratory acidosis, not necessarily decreased.
