LPN Fundamentals of Nursing Test Questions
Question 1 of 5
The physician of your assigned client tells you that the client has a heart murmur that can be detected by direct auscultation. You realize that the physician is telling you which of the following things?
Correct Answer: A
Rationale: Direct auscultation means using a stethoscope to hear a murmur, standard for heart sounds. Ear alone, ultrasound, or Doppler aren't implied. Nurses apply this in cardiac exams.
Question 2 of 5
Which respiratory complication is commonly associated with immobility?
Correct Answer: B
Rationale: Immobility often causes hypoxia due to shallow breathing and limited lung expansion, reducing oxygen delivery to tissues a frequent issue in sedentary patients. This stems from decreased chest movement, risking conditions like atelectasis. Excessive breathing isn't typical, as immobility slows respiratory effort, not accelerates it. Low or high blood pressure relates more to cardiovascular dynamics than lung function in this context. Nurses address this by encouraging deep breathing or repositioning, countering the oxygen deficit that immobility fosters, ensuring respiratory health remains a priority in care planning.
Question 3 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 4 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 5 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.
