LPN Fundamentals of Nursing Test Questions
Question 1 of 5
When working with clients experiencing pain, you will define their pain in regard to whether they have pain or not and how intense it is based on which of the following things?
Correct Answer: C
Rationale: Pain is defined by the client's self-report, per McCaffery's standard, not nurse expertise, cause, or research. Nurses honor this subjective experience for care.
Question 2 of 5
A client with severe hypoxemia requires oxygen therapy. What is the appropriate delivery method for this client?
Correct Answer: D
Rationale: For a client with severe hypoxemia, a non-rebreather mask (D) is the most appropriate delivery method because it delivers the highest oxygen concentration up to 95% via a reservoir bag and one-way valves that prevent rebreathing exhaled air, ensuring maximal oxygen intake. Nasal cannula (A) provides low flow (24-44% oxygen) and suits mild hypoxemia, not severe cases. Simple face mask (B) offers moderate oxygen (40-60%) for stable needs, inadequate for severe hypoxemia. Venturi mask (C) delivers precise oxygen (24-50%) for conditions like COPD but not the high levels needed here. The non-rebreather's design addresses acute oxygen deficits effectively, critical in emergencies like severe hypoxemia, aligning with respiratory care standards to prevent tissue hypoxia and organ damage, per AACN guidelines.
Question 3 of 5
A nurse is caring for a client receiving oxygen therapy via a Venturi mask. What is an important nursing intervention for this client?
Correct Answer: B
Rationale: Adjusting the oxygen flow rate as prescribed (B) is essential for a Venturi mask, ensuring the exact FiO2 (24-50%) matches the order for precise delivery. Continuous SpO2 (A) may be excessive. Lung sounds q-shift (C) are routine. Loose fit (D) reduces accuracy. Prescription adherence, per respiratory standards, optimizes therapy.
Question 4 of 5
An elderly client who experiences nighttime confusion wanders from his room into the room of another client. The nurse can best help decrease the client's confusion by:
Correct Answer: D
Rationale: A night light reduces nighttime confusion in elderly clients by improving visibility, orienting them to their surroundings, and decreasing disorientation a common, non-invasive dementia strategy. Constant supervision, room-sharing, or sedatives are less practical or riskier, potentially increasing agitation or falls. Nurses implement this to enhance safety and comfort, minimizing wandering without restricting autonomy excessively.
Question 5 of 5
Which of the following conditions is most likely related to the development of renal calculi?
Correct Answer: A
Rationale: Gout increases renal calculi risk due to elevated uric acid levels forming stones, a metabolic link well-documented in nephrology unlike pancreatitis (calcium stones rarely), fractures, or disc disease, which lack direct renal impact. Nurses connect this condition to stone formation for prevention teaching, like hydration and dietary purine reduction, addressing a client's predisposition to this painful urologic issue.
