What is the term used to describe the movement of fluid into the third space, making it unavailable for physiological use?
Fluid shift
Fluid transfer
Fluid retention
Fluid expansion
The Correct Answer is A
A. Fluid shift: Third-spacing refers to the movement of fluid from the intravascular or intracellular compartments into interstitial or potential spaces where it is physiologically unavailable. This can lead to hypovolemia, edema, and decreased tissue perfusion. Common causes include burns, severe infections, and liver or kidney disease.
B. Fluid transfer: Fluid transfer is a nonspecific term and does not capture the pathophysiologic concept of fluid accumulation in nonfunctional compartments. It lacks the clinical significance associated with third-spacing.
C. Fluid retention: Fluid retention generally refers to the overall accumulation of fluid in the body, often within the vascular or interstitial space, but does not specifically describe fluid sequestered in a third space.
D. Fluid expansion: Fluid expansion refers to increasing circulating volume, often through intravenous fluid administration. It does not describe the pathological movement of fluid into compartments where it is unavailable for normal physiologic use.

Correct Answer is A
Explanation
A. Holds many responsibilities: The nurse is responsible for safely preparing, verifying, administering, and monitoring medications. This includes assessing the client’s condition, identifying potential contraindications, observing for adverse effects, and documenting accurately. The nurse must also educate the client and respond promptly to any complications.
B. Has very few responsibilities: Medication administration carries significant responsibilities for safety, accuracy, and client monitoring. Minimizing the nurse’s role would compromise patient care and increase the risk of errors.
C. Delegates all tasks to other personnel because she is too busy: While certain support tasks can be delegated, the nurse cannot delegate the assessment, verification, administration, and monitoring of medications. These are critical responsibilities that require professional judgment.
D. Only prepares medications: Preparing medications is only one part of the nurse’s role. Safe administration also requires verification, monitoring, documentation, and client education, which go beyond mere preparation.
Correct Answer is D
Explanation
Calculation:
- Identify the total amount of medication and the total volume after reconstitution
Total Medication: 1 g = 1000 mg
Volume added: 4 mL
- Calculate the concentration
Concentration = Total Medication ÷ Total Volume
Concentration = 1000 ÷ 4
= 250 mg/mL
