LPN Fundamentals Practice Test Questions
Question 1 of 5
A client asks you how to best prevent vaginal infections. Your best answer would include which of the following statements?
Correct Answer: B
Rationale: Explaining that vaginal pH stops many bacteria is true and educational, highlighting the body's natural defense against infections like bacterial vaginosis. Vinegar douches disrupt this balance, cranberry juice aids urinary health not vaginal, and medications aren't preventive norms. This empowers the client with knowledge, a key nursing role in infection prevention.
Question 2 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 3 of 5
Which intervention is important for maintaining the safety of an immobile patient?
Correct Answer: D
Rationale: Implementing fall prevention measures is critical for an immobile patient's safety, involving tools like bed alarms, low beds, or assistance during transfers to mitigate risks in a controlled environment. Immobile patients can't walk independently, so promoting frequent movement isn't feasible and could increase danger. Physical or soft restraints, while sometimes considered, are last-resort options due to ethical and safety concerns, not primary safety strategies. Fall prevention directly addresses the vulnerability of those unable to reposition themselves, reducing injury risk a key nursing responsibility. This approach ensures a safe setting, balancing protection with patient dignity, and aligns with evidence-based practice to minimize harm in immobile populations.
Question 4 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 5 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.
