LPN Fundamentals Questions
Question 1 of 5
The thoracic and abdominopelvic cavities are divided by which of the following body structures?
Correct Answer: B
Rationale: The diaphragm separates thoracic and abdominopelvic cavities, aiding breathing. Ribs and sternum encase, stomach resides below. Nurses use this in respiratory assessments.
Question 2 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 3 of 5
Which intervention should the nurse prioritize for a patient with impaired mobility to prevent respiratory complications?
Correct Answer: C
Rationale: Encouraging deep breathing and coughing prevents respiratory complications like atelectasis in impaired-mobility patients by clearing airways and expanding lungs. Oxygen treats symptoms, spirometry aids expansion but isn't primary, and antibiotics aren't routine. Nurses prioritize this to enhance ventilation, countering immobility's respiratory suppression, a simple yet effective strategy for lung health maintenance.
Question 4 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 5 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.
