LPN Fundamentals Practice Test Questions
Question 1 of 5
The nurse is taking the client's blood pressure. The physician asks for the pulse pressure. To obtain the pulse pressure, the nurse will have to do which of the following things?
Correct Answer: B
Rationale: Pulse pressure is systolic minus diastolic pressure, reflecting arterial force, not requiring machines or pulse rates. Nurses calculate this for cardiovascular insight.
Question 2 of 5
Which nursing intervention is essential to prevent pressure ulcers in a patient with limited mobility?
Correct Answer: A
Rationale: Frequent, thorough skin assessments are essential to prevent pressure ulcers in limited-mobility patients, catching early redness or breakdown for timely intervention. Petroleum jelly doesn't relieve pressure, air mattresses aid but aren't enough alone, and prolonged sitting increases risk. Nurses rely on this to monitor skin health, enabling prompt action like repositioning, crucial for preventing progression to ulcers in at-risk areas.
Question 3 of 5
A nurse is caring for a client receiving oxygen therapy via a nasal cannula. What is an important complication associated with prolonged use of a nasal cannula?
Correct Answer: A
Rationale: Dry nasal passages (A) are a common complication of prolonged nasal cannula use, as unhumidified oxygen dries mucosa, causing discomfort or bleeding. Hypoventilation (B) isn't typical with low-flow devices. Hyperoxygenation (C) requires higher flows. Infection risk (D) isn't direct. Humidification prevents this, per nursing care, ensuring patient tolerance.
Question 4 of 5
A mother of a 3-year-old hospitalized with lead poisoning asks the nurse to explain the treatment for her daughter. The nurse's explanation is based on the knowledge that lead poisoning is treated with:
Correct Answer: B
Rationale: Lead poisoning is treated with chelating agents like succimer or EDTA, which bind lead in the bloodstream, facilitating its excretion and reducing toxicity a standard protocol for elevated blood levels. Gastric lavage or charcoal addresses acute ingestion, not chronic exposure common in children, while antiemetics manage symptoms, not the cause. Nurses explain this to parents, emphasizing chelation's role in reversing neurological and systemic damage, ensuring understanding of the treatment's purpose and process.
Question 5 of 5
A client with a bowel resection and anastomosis returns to his room with an NG tube attached to intermittent suction. Which of the following observations indicates that the nasogastric suction is working properly?
Correct Answer: A
Rationale: A soft abdomen indicates effective nasogastric suction post-bowel resection, decompressing the stomach and intestines, preventing distension or leakage at the anastomosis site. Swallowing ability, bowel sounds, or dressing condition don't directly confirm suction efficacy distension relief does. Nurses monitor this to ensure gastrointestinal rest, reducing complications like ileus or suture strain, supporting healing in a client recovering from major abdominal surgery.
