ATI Fluid Electrolyte and Acid-Base Regulation

1. .A nurse assesses a clients peripheral IV site, and notices edema and tenderness above the site. Which action should the nurse take next?

A. Apply cold compresses to the IV site.
B. Elevate the extremity on a pillow.
C. Flush the catheter with normal saline.
D. . Stop the infusion of intravenous fluids.

Correct answer: D

Rationale:

2. Which hormones increase the amount of water in the body?

A. ADH
B. Aldosterone
C. ANH
D. ADH and aldosterone

Correct answer: D

Rationale: The correct answer is D, ADH and aldosterone. Both antidiuretic hormone (ADH) and aldosterone increase water retention by the kidneys, thereby increasing blood volume. ADH acts on the kidneys to increase water reabsorption, while aldosterone acts on the kidneys to promote sodium reabsorption, leading to water retention. Choice A, ADH, is partially correct as it alone increases water retention. Choice B, aldosterone, is also partially correct as it alone increases water retention. Choice C, ANH (atrial natriuretic hormone), actually decreases water retention by promoting sodium excretion and inhibiting aldosterone release.

3. Which substance dissociates into ions in a water solution?

A. Intracellular fluid
B. Interstitial fluid
C. Plasma
D. Electrolyte

Correct answer: D

Rationale: The correct answer is 'Electrolyte.' Electrolytes are substances that dissociate into ions when dissolved in water. Intracellular fluid, interstitial fluid, and plasma are not substances that dissociate into ions in a water solution. Intracellular fluid is the fluid inside cells, interstitial fluid is the fluid between cells, and plasma is the liquid component of blood. These choices do not dissociate into ions in a water solution, unlike electrolytes.

4. A nurse is assessing a client who has an electrolyte imbalance related to renal failure. For which potential complications of this electrolyte imbalance should the nurse assess? (Select all that do mot apply.)

A. Electrocardiogram changes
B. Slow, shallow respirations
C. Paralytic ileus
D. Skeletal muscle weakness

Correct answer: B

Rationale:

5. The healthcare provider is evaluating a patient's laboratory results. Based on the laboratory findings, what results will cause the release of an antidiuretic hormone (ADH)?

A. Increased serum sodium
B. Decreased serum sodium
C. Decrease in serum osmolality
D. Decrease in thirst

Correct answer: A

Rationale: The correct answer is A: Increased serum sodium. When serum sodium levels increase, it triggers the release of ADH by the posterior pituitary gland. ADH helps in retaining water, reducing urine output, and maintaining fluid balance. Choices B, C, and D are incorrect because decreased serum sodium, decrease in serum osmolality, and decrease in thirst do not stimulate the release of ADH.
