LPN Fundamentals Questions
Question 1 of 5
The nurse is checking the placement of a nasogastric tube prior to giving medication and a feeding. Which of the following is the preferred and most accurate method of testing?
Correct Answer: B
Rationale: Aspirating secretions and testing pH (acidic for stomach) is the most accurate NG tube placement check, unlike air sounds, water, or bubbles, which are less reliable. Nurses use this for safety.
Question 2 of 5
A nurse is caring for a client receiving oxygen therapy via a Venturi mask. What is an important nursing consideration for this client?
Correct Answer: B
Rationale: Monitoring for oxygen toxicity (B) is crucial with a Venturi mask, as prolonged high oxygen (e.g., >50%) can cause lung damage or CNS symptoms like seizures. Hourly RR (A) is routine, not specific. Supplemental oxygen (C) is the mask's purpose. Tight fit (D) isn't unique to Venturi. Vigilance for toxicity, per nursing standards, protects against overuse.
Question 3 of 5
The physician has ordered dressings with mafenide acetate (Sulfamylon) cream for a client with full-thickness burns of the hands and arms. Before dressing changes, the nurse should give priority to:
Correct Answer: A
Rationale: Mafenide acetate cream causes significant burning pain upon application to full-thickness burns, making pain management the priority before dressing changes to ensure client comfort and cooperation. Urinary output, blood counts, and glucose levels are important but secondary in this context, as they monitor systemic effects rather than immediate procedural needs. Nurses administer analgesics proactively, timing them to peak during dressing changes, balancing pain relief with ongoing burn care to support healing and reduce distress.
Question 4 of 5
The nurse is caring for a client with laryngeal cancer. The client's daughter asks the nurse how her father got cancer of the larynx. The nurse should explain that one risk factor is:
Correct Answer: D
Rationale: Cigarette smoking is a primary risk factor for laryngeal cancer, as tobacco's carcinogens directly irritate and mutate laryngeal tissues over time, a well-established link in oncology. Tuberculosis affects the lungs, not typically the larynx, while wood dust and air pollution are more associated with nasal or lung cancers. Nurses educate families on this connection, emphasizing smoking cessation to reduce risk, framing it as a preventable factor. This explanation addresses the daughter's query with clarity, grounding it in the client's likely history, and supports broader health teaching to mitigate future risks in the family.
Question 5 of 5
The nurse is caring for a client following a right total knee replacement. Which of the following should be included in the plan of care?
Correct Answer: D
Rationale: Checking the continuous passive motion (CPM) device is key post-right total knee replacement, ensuring it maintains joint mobility and prevents stiffness flat legs, pillows under knees, or prone positioning counter recovery goals. Nurses monitor CPM settings, promoting circulation and range of motion, critical for rehabilitation success.
