A patient experiencing multisystem fluid volume deficit has tachycardia, pale, cool skin, and decreased urine output. The nurse realizes these findings are most likely a direct result of which process?

Effects of rapidly infused intravenous fluids.

The body's natural compensatory mechanisms.

Pharmacological effects of a diuretic.

Cardiac failure.

Answer and Explanation

The Correct Answer is B

Choice B rationale:

The patient's tachycardia, pale, cool skin, and decreased urine output are signs of the body's natural compensatory mechanisms in response to fluid volume deficit. When the body

experiences a decrease in fluid volume, it tries to compensate by increasing heart rate (tachycardia) to maintain blood flow to vital organs and constricting blood vessels to preserve fluid and maintain blood pressure. Pale, cool skin is a result of vasoconstriction, and decreased urine output is a way the body conserves water during dehydration.

Choice A rationale:

Effects of rapidly infused intravenous fluids are not the cause of the patient's current findings. In fact, the nurse's notes indicate that the IV fluid therapy (0.9% sodium chloride) was initiated at 125 mL/hr, which is a relatively standard and cautious rate. Rapidly infused fluids could potentially cause fluid overload, but that is not the situation here.

Choice C rationale:

Pharmacological effects of a diuretic are not relevant to this patient's presentation. There is no mention of diuretic use in the nurse's notes, and the symptoms presented are more consistent with fluid volume deficit and dehydration rather than diuretic use.

Choice D rationale:

Cardiac failure is not the correct answer, as there is no indication of heart failure in the patient's presentation or nurse's notes. The symptoms and findings described are more indicative of fluid volume deficit, which is not synonymous with cardiac failure.

Correct Answer is A

Explanation

The correct answer is choice A. Client has an NG tube to gastric suction.

Choice A rationale:

Having an NG tube to gastric suction can lead to hypokalemia because the suctioning process removes potassium from the stomach contents, leading to a decrease in serum potassium levels.

Choice B rationale:

While a history of alcohol abuse disorder can lead to various electrolyte imbalances, it is not the most direct cause of hypokalemia compared to gastric suction.

Choice C rationale:

Drinking 3.5 to 4 liters of water each day can lead to dilutional hyponatremia but is less likely to cause hypokalemia directly.

Choice D rationale:

Spironolactone is a potassium-sparing diuretic, which means it helps retain potassium in the body. Therefore, it is not a causative factor for hypokalemia.

A. Patient with bulimia. B. Patient with COPD. C. Patient with venous stasis ulcer. D. Patient on dialysis.

Correct Answer is A

Explanation

Choice A rationale: Patients with bulimia are at increased risk for developing metabolic alkalosis due to recurrent vomiting, which leads to loss of hydrochloric acid from the stomach and results in an elevated blood bicarbonate level.

Choice B rationale: Patients with COPD are more likely to develop respiratory acidosis due to retention of carbon dioxide, not metabolic alkalosis.

Choice C rationale: Patients with venous stasis ulcers do not have a direct association with metabolic alkalosis.

Choice D rationale: Patients on dialysis are more likely to experience metabolic acidosis due to impaired kidney function and inability to excrete acid effectively.
