Nursing Elites

1. What happens first in dehydration?

• A. Intercellular fluid volume drops first.
• B. Plasma volume drops first.
• C. Interstitial fluid drops first.
• D. Neither interstitial nor intracellular fluid volume are affected.

Correct answer: C

Rationale: In dehydration, the body first draws fluid from the interstitial space to maintain blood volume, leading to a decrease in interstitial fluid volume. This is why choice C is correct. Choice A is incorrect because intracellular fluid is not the first to be affected. Choice B is also incorrect as plasma volume reduction typically occurs after interstitial fluid loss. Choice D is incorrect as dehydration impacts both interstitial and intracellular fluid volumes.

2. Diagnostic testing has been ordered to differentiate between normal anion gap acidosis and high anion gap acidosis in an acutely ill patient. What health problem typically precedes normal anion gap acidosis?

• A. Metastases
• B. Excessive potassium intake
• C. Water intoxication
• D. Excessive administration of chloride

Correct answer: D

Rationale:

3. 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.)

• A. Use a draw sheet to reposition the client in bed.
• B. . Strain all urine output and assess for urinary stones.
• C. Provide nonslip footwear for the client to use when out of bed.
• D.

Correct answer: B

Rationale:

4. Which of the following organs does not contribute to fluid output from the body?

• A. Lungs
• B. Skin
• C. Intestine
• D. Lungs, skin, and intestine

Correct answer: D

Rationale: The correct answer is D. All the listed organs (lungs, skin, and intestines) contribute to fluid loss from the body. Lungs contribute to fluid loss through respiration, skin through sweating, and intestines through excretion. Therefore, none of the organs listed in the options retain fluids within the body. Choices A, B, and C are incorrect because all of these organs play a role in fluid output from the body.

5. A patient has questioned the nurses administration of IV normal saline, asking whether sterile water would be a more appropriate choice than saltwater. Under what circumstances would the nurse administer electrolyte-free water intravenously?

• A. Never, because it rapidly enters red blood cells, causing them to rupture.
• B. When the patient is severely dehydrated resulting in neurologic signs and symptoms
• C. When the patient is in excess of calcium and/or magnesium ions
• D. When a patients fluid volume deficit is due to acute or chronic renal failure

Correct answer: A
