Nursing Fundamentals Exam for LPN Questions
Question 1 of 5
Tissue in the urinary bladder called transitional epithelium is best described in which of the following ways?
Correct Answer: D
Rationale: Transitional epithelium changes shape with bladder fullness, stretching thin when full, a unique adaptation. It's stratified, not single-layered, and lacks special elastic substances. This aids nursing assessment of urinary function.
Question 2 of 5
The nurse will teach clients to use which of the following groups from the food pyramid in the greatest amounts?
Correct Answer: A
Rationale: Carbohydrates like grains form the food pyramid base, recommended most for energy, over vegetables, dairy, or proteins. Nurses teach this for balanced diets.
Question 3 of 5
Which nursing intervention promotes mobility for a patient who has been on bed rest for an extended period?
Correct Answer: B
Rationale: Assisting with passive range of motion exercises promotes mobility in a bedridden patient by maintaining joint flexibility and preventing stiffness, countering immobility's effects. Staying in bed or restricting movement worsens deconditioning, and restraints hinder progress. Nurses implement this to gradually restore function, supporting circulation and muscle health, a vital step toward active mobility in prolonged rest scenarios.
Question 4 of 5
A client with sleep apnea requires positive pressure ventilation during sleep. Which oxygen delivery system would be most appropriate for this client to ensure continuous positive airway pressure (CPAP)?
Correct Answer: D
Rationale: A CPAP mask (D) is most appropriate for sleep apnea, delivering constant pressure to keep airways open, improving oxygenation and sleep quality. Nasal cannula (A), Venturi (B), and non-rebreather (C) don't provide pressure support. CPAP is the gold standard, per sleep medicine, addressing apnea effectively.
Question 5 of 5
A client hospitalized with chronic dyspepsia is diagnosed with gastric cancer. Which of the following is associated with an increased incidence of gastric cancer?
Correct Answer: D
Rationale: Luncheon meats, high in nitrates and preservatives, are linked to gastric cancer due to their conversion into carcinogenic nitrosamines in the stomach, a risk factor supported by dietary studies. Dairy, carbonated drinks, and refined sugars may contribute to other health issues but lack a strong direct association with gastric cancer. Processed meats' chemical content irritates gastric mucosa over time, increasing malignancy risk. Nurses use this knowledge for dietary counseling, helping clients reduce exposure to such risk factors, enhancing prevention strategies alongside treatment for existing conditions.
