LPN Fundamentals Practice Test Questions
Question 1 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 2 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.
Question 3 of 5
The physician has ordered cultures for cytomegalovirus (CMV). Which statement is true regarding collection of cultures for cytomegalovirus?
Correct Answer: D
Rationale: Accurate CMV diagnosis relies on fresh specimens (e.g., urine, saliva), as the virus's viability drops quickly, critical for PCR or culture confirmation unlike stool, pregnant staff safety, or single samples. Nurses ensure prompt lab delivery, protecting immunocompromised clients from missed detection.
Question 4 of 5
A client with a history of renal failure is admitted with shortness of breath and substernal chest pain. Which of the following laboratory values should be reported to the physician immediately?
Correct Answer: A
Rationale: Potassium 6.2 mEq/L (normal 3.5-5.0) in renal failure with chest pain and dyspnea signals hyperkalemia, risking cardiac arrhythmias urgent for physician report. Creatinine elevation is expected, hemoglobin and sodium are normal. Nurses flag this, as it ties to symptoms, prompting ECG and potassium-lowering measures.
Question 5 of 5
The nurse is caring for a client with a Sengstaken-Blakemore tube. To prevent ulceration of the nares while the tube is in place, the nurse should:
Correct Answer: C
Rationale: Applying water-soluble lubricant to the nares prevents ulceration with a Sengstaken-Blakemore tube, reducing friction oil-based lubricants risk aspiration, tight taping increases pressure, and peroxide irritates. Nurses maintain nasal care, ensuring comfort and preventing tissue breakdown during esophageal varices treatment.
