ATI Fluid Electrolyte and Acid-Base Regulation

1. You are the nurse caring for a patient who is to receive IV daunorubicin, a chemotherapeutic agent. You start the infusion and check the insertion site as per protocol. During your most recent check, you note that the IV has infiltrated so you stop the infusion. What is your main concern with this infiltration?

A. Extravasation of the medication
B. Discomfort to the patient
C. Blanching at the site
D. Hypersensitivity reaction to the medication

Correct answer: A

Rationale:

2. 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.

3. A gerontologic nurse is teaching students about the high incidence and prevalence of dehydration in older adults. What factors contribute to this phenomenon? Select all that do not apply.

A. Decreased kidney mass
B. Decreased renal blood flow
C. Decreased excretion of potassium
D. Increased conservation of sodium

Correct answer: D

Rationale:

4. The chief mechanism for maintaining fluid balance is to:

A. adjust fluid intake so it equals fluid output.
B. adjust fluid intake so it is slightly above fluid output.
C. adjust fluid output so it equals fluid input.
D. adjust fluid intake so it is slightly below fluid output.

Correct answer: C

Rationale: The correct answer is C: 'adjust fluid output so it equals fluid input.' Maintaining fluid balance involves ensuring that the amount of fluid lost through processes like urination, sweating, and respiration equals the amount of fluid taken in. This ensures that the body stays properly hydrated. Choices A, B, and D are incorrect because they do not focus on the balance between fluid input and output, which is crucial for maintaining proper fluid balance. By adjusting fluid output to equal fluid input, the body can regulate hydration levels effectively, preventing dehydration or overhydration.
