LPN Fundamentals Study Guide Questions
Question 1 of 5
Your assigned client has a leg ulcer that has a dressing on it. During your assessment, you find that the dressing is wet. The client admits to spilling water on the dressing. What action would be best on your part?
Correct Answer: B
Rationale: A wet dressing from water spill requires removal and replacement to prevent infection and maintain a healing environment. Reinforcing keeps moisture, drying with a hairdryer risks burns or contamination, and air drying is slow and ineffective. This action ensures wound integrity, a core nursing responsibility.
Question 2 of 5
When pain impulses are transmitted via the A-delta fibers, which of the following types of pain will your client have?
Correct Answer: A
Rationale: A-delta fibers transmit sharp, pricking pain, fast and localized, unlike throbbing, burning, or stabbing via C-fibers. Nurses recognize this for pain type assessment.
Question 3 of 5
Which gastrointestinal effect is commonly seen in immobile patients?
Correct Answer: C
Rationale: Constipation frequently affects immobile patients as reduced movement slows peristalsis and increases intestinal water absorption, hardening stool. This disruption in bowel function is a well-documented outcome of limited physical activity, requiring nursing interventions like hydration or laxatives. Appetite doesn't typically rise with immobility, nor does peristalsis speed up it diminishes. Diarrhea isn't a standard effect unless other factors intervene. Nurses tackle this to restore regularity, understanding that immobility's impact on digestion underscores the need for proactive gastrointestinal care in such patients.
Question 4 of 5
When administering oxygen therapy, what should the nurse prioritize to ensure the safety of the client?
Correct Answer: B
Rationale: Monitoring oxygen saturation levels (B) via pulse oximetry is the priority in oxygen therapy safety, as it directly assesses oxygenation effectiveness, ensuring the client's needs are met (target SpO2 typically 92-98%). Respiratory rate (A) is a vital sign but doesn't quantify oxygen delivery. Dyspnea (C) is subjective and less precise than objective SpO2 readings. Adjusting flow rate (D) depends on saturation data, making it secondary. Continuous or frequent SpO2 monitoring detects hypoxemia or hyperoxia early, guiding interventions to prevent complications like respiratory depression or tissue damage, a cornerstone of safe oxygen administration per nursing protocols.
Question 5 of 5
When administering oxygen therapy, which intervention should the nurse prioritize to ensure the delivery of the prescribed oxygen concentration?
Correct Answer: C
Rationale: Monitoring oxygen saturation continuously (C) ensures the prescribed oxygen concentration is effective, allowing real-time adjustments to maintain target SpO2. Hourly RR (A) is indirect. Q4h flow checks (B) miss immediate issues. Snug mask (D) aids fit, not concentration. Continuous SpO2, per nursing protocols, guides safe delivery.
