What is the primary reason for administering isotonic crystalloid IV fluids to a client with fluid volume deficit?
To replace lost blood components
To restore extracellular fluid volume
To replenish electrolytes rapidly
To correct metabolic acidosis
The Correct Answer is B
Rationale:
A. Replacing lost blood components requires blood products, not isotonic crystalloids.
B. Isotonic crystalloid fluids (e.g., 0.9% sodium chloride, lactated Ringer’s) are administered to restore extracellular fluid volume in clients with fluid volume deficit.
C. While isotonic solutions contain electrolytes, their primary purpose is volume replacement, not rapid electrolyte correction.
D. Correcting metabolic acidosis may require specific interventions; isotonic fluids alone do not address acid-base imbalances.

Correct Answer is ["B","E","F"]
Explanation
Rationale:
A. Family history increases risk for heart disease and arthritis but is not a direct risk factor for peptic ulcer disease.
B. Smoking increases gastric acid secretion, reduces mucosal healing, and significantly raises PUD risk.
C. Alcohol use is denied by the client and therefore is not a contributing factor in this case.
D. Adalimumab use (an immunosuppressant for rheumatoid arthritis/psoriasis) does not directly increase PUD risk.
E. NSAIDs inhibit prostaglandin synthesis, reducing the gastric mucosal barrier and predisposing to ulcer formation.
F. H. pylori infection is a primary cause of peptic ulcers due to its damaging effect on gastric mucosa.
Correct Answer is B
Explanation
Rationale:
A. Obtaining a dietary history is important but not the priority in an acute exacerbation.
B. Reviewing electrolyte values is the first action. Clients with acute ulcerative colitis are at risk for fluid and electrolyte imbalances due to diarrhea, making this a priority assessment to prevent complications.
C. Investigating emotional concerns is important for holistic care but is secondary to addressing physiologic needs.
D. Checking perianal skin integrity is necessary but comes after assessing critical physiologic risks like electrolyte imbalances.
