LPN Fundamentals Questions
Question 1 of 5
A client asks you to explain viruses. Which of the following statements would be true and therefore best to include in your answer?
Correct Answer: C
Rationale: Explaining that viruses must enter living cells to reproduce is true and fundamental, distinguishing them from bacteria. Viruses lack cellular machinery, relying on host cells, unlike Candida, a fungus. They aren't the most common infectious agents universally, nor primarily intestinal. This fact educates the client accurately, aiding understanding of viral infections like flu, a key nursing teaching point.
Question 2 of 5
In which of the following clients is a rectal temperature most usually contraindicated?
Correct Answer: A
Rationale: Rectal temperature is contraindicated post-myocardial infarction due to vagal stimulation risking cardiac complications, unlike in Parkinson's, seizures, or neuropathy. Nurses avoid this for safety.
Question 3 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 4 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 5 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.
