In which type of water would a submersion injury cause the patient's fluid to be drawn from the vascular space into the alveoli, impairing alveolar ventilation and resulting in hypoxia?

Hypotonic saltwater.

Hypertonic saltwater.

Hypotonic freshwater.

Hypertonic freshwater.

Answer and Explanation

The Correct Answer is B

The correct answer is B. Hypertonic saltwater.

Choice A rationale: Hypotonic saltwater would not cause significant fluid shifts into the alveoli. Instead, it would cause cells to swell due to the lower concentration of solutes outside the cells.

Choice B rationale: Hypertonic saltwater causes fluid to be drawn from the vascular space into the alveoli due to the higher concentration of solutes in the water compared to the body's cells. This can impair alveolar ventilation and result in hypoxia.

Choice C rationale: Hypotonic freshwater would cause cells to swell and potentially burst due to the lower concentration of solutes outside the cells, but it would not specifically cause fluid to be drawn into the alveoli.

Choice D rationale: Hypertonic freshwater is not a common classification for drowning water. Freshwater is typically hypotonic compared to body fluids, and it would not cause the same fluid shift as hypertonic saltwater.

Correct Answer is C

Explanation

Choice A rationale:

While pregnancy can contribute to increased blood pressure, it is not the priority question in this scenario. The sudden rise in blood pressure could indicate a hypertensive crisis, which needs immediate attention.

Choice B rationale:

Urination is not directly related to sudden rises in blood pressure. While urinary issues could be a sign of certain conditions, they are not the priority when dealing with a hypertensive emergency.

Choice C rationale:

A sudden rise in blood pressure can lead to symptoms such as headache and confusion, which could indicate a hypertensive crisis. This question is crucial to assess neurological symptoms, which can be indicative of target organ damage due to hypertension.

Choice D rationale:

Antiseizure medications are not directly related to sudden increases in blood pressure. Neurological symptoms (like those in choice C) are more indicative of a hypertensive crisis and require immediate attention.

A. Metabolic acidosis. B. Metabolic alkalosis. C. Respiratory acidosis. D. Respiratory alkalosis.

Correct Answer is C

Explanation

Choice A rationale:

Metabolic acidosis is characterized by low blood pH and low bicarbonate ion levels. The patient's bicarbonate ion level (24 mEq/L) is within the normal range, and the low pH (7.32) and elevated PaCO2 (56 mm Hg) indicate respiratory acidosis, not metabolic acidosis.

Choice B rationale:

Metabolic alkalosis is characterized by high blood pH and high bicarbonate ion levels. The patient's pH is low (7.32), and the bicarbonate ion level (24 mEq/L) is within the normal range, indicating respiratory acidosis rather than metabolic alkalosis.

Choice C rationale:

Respiratory acidosis is characterized by low blood pH and high PaCO2 levels. In this case, the patient has a low pH (7.32) and elevated PaCO2 (56 mm Hg), indicating respiratory acidosis. The bicarbonate ion level (24 mEq/L) is a compensatory response. Respiratory alkalosis would present with high pH and low PaCO2 levels.

Choice D rationale:

Respiratory alkalosis is characterized by high blood pH and low PaCO2 levels. The patient's PaCO2 level is elevated (56 mm Hg), indicating respiratory acidosis, not alkalosis. The low pH (7.32) further supports the diagnosis of respiratory acidosis.
