ATI Fluid Electrolyte and Acid-Base Regulation

1. . A nurse is planning care for a nephrology patient with a new nursing graduate. The nurse states, A patient in renal failure partially loses the ability to regulate changes in pH. What is the cause of this partial inability?

Correct answer: C

Rationale:

2. Which hormone reduces the amount of water in the body?

Correct answer: B

Rationale: The correct answer is 'aldosterone.' Aldosterone is the hormone that reduces the amount of water in the body by increasing the reabsorption of sodium and water from the kidney tubules. ANH (atrial natriuretic hormone) actually works to increase the excretion of sodium and water by the kidneys, leading to a reduction in blood volume and pressure. ADH (antidiuretic hormone) works to increase water reabsorption by the kidneys, thereby increasing blood volume. Therefore, choices A (ADH) and D (ADH and aldosterone) are incorrect in the context of reducing the amount of water in the body.

3. You are working on a burns unit, and one of your acutely ill patients is exhibiting signs and symptoms of third spacing. Based on this change in status, you should expect the patient to exhibit signs and symptoms of what imbalance?

Correct answer: D

Rationale: Third spacing refers to the loss of fluid from the intravascular space into the interstitial or third space, leading to a decrease in circulating blood volume. This condition results in hypovolemia, which is characterized by decreased blood volume. Metabolic alkalosis, hypermagnesemia, and hypercalcemia are not directly associated with third spacing. Metabolic alkalosis is an acid-base imbalance, hypermagnesemia is an excess of magnesium in the blood, and hypercalcemia is an excess of calcium in the blood, none of which are the primary concerns in cases of third spacing.

4. A nurse develops a plan of care for a client who has a history of hypocalcemia. What interventions should the nurse include in this clients care plan? (Select all that apply.)

Correct answer: B

Rationale:

5. The term used to describe a blood sodium level of more than 145 mEq/L is:

Correct answer: C

Rationale: The correct answer is C: hypernatremia. Hypernatremia refers to an elevated level of sodium in the blood, specifically when it is more than 145 mEq/L. Choice A, hyponatremia, is incorrect as it refers to low sodium levels. Choice B, hyperkalemia, is incorrect as it refers to high potassium levels, not sodium. Choice D, hypercalcemia, is also incorrect as it relates to elevated calcium levels, not sodium.
