LPN Fundamentals Exam Questions
Question 1 of 5
When talking with a client about complete and incomplete proteins, which of the following would you use as the best example of a complete protein?
Correct Answer: C
Rationale: Eggs are a complete protein, containing all essential amino acids, unlike olives, rice, or nuts (incomplete). Nurses teach this for nutrition.
Question 2 of 5
A client with a traumatic brain injury (TBI) develops altered mental status and decreased oxygen saturation. What is the primary indication for initiating oxygen therapy in this client?
Correct Answer: D
Rationale: Ensuring adequate oxygen supply to the brain (D) is the primary indication for oxygen therapy in TBI with altered status and low SpO2, preventing hypoxic brain damage. Cerebral edema (A) or BP stabilization (C) involves other interventions. Neurological improvement (B) follows oxygenation. Adequate oxygen supports cerebral metabolism, per neurotrauma care, critical to limit secondary injury.
Question 3 of 5
The nurse is caring for a client receiving oxygen therapy via a Venturi mask. Which assessment finding indicates the need for adjustment of the oxygen flow rate?
Correct Answer: C
Rationale: Nasal dryness and discomfort (C) indicate inadequate humidification with a Venturi mask, necessitating flow or humidity adjustment. SpO2 98% (A) and RR 16 (B) are normal. 4 L/min (D) may be correct but doesn't address symptoms. Adjustment, per respiratory care, improves tolerance and efficacy.
Question 4 of 5
Which of the following snacks would be suitable for the child with gluten-induced enteropathy?
Correct Answer: B
Rationale: Buttered popcorn is suitable for gluten-induced enteropathy (celiac disease), as corn is naturally gluten-free, unlike oatmeal, wheat bread, or pizza crust, which contain gluten and damage the intestine. Nurses guide dietary choices to avoid gluten, preventing malabsorption and symptoms like diarrhea, ensuring nutritional health for affected children.
Question 5 of 5
A 3-year-old is immobilized in a hip spica cast. Which discharge instruction should be given to the parents?
Correct Answer: D
Rationale: Avoiding dolls or small toys prevents them from lodging in the spica cast, reducing skin irritation or infection risks for a 3-year-old a practical discharge tip. Flat beds, coloring books, or calorie boosts are less critical or unrelated to cast care. Nurses stress this to maintain cast integrity, ensuring safe immobilization for hip healing.
