Fundamentals of Nursing Oxygenation NCLEX Questions Questions
Question 1 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: Oxygen toxicity can occur with prolonged exposure to high levels of oxygen. The nurse should closely monitor the client for signs of oxygen toxicity, such as substernal pain, respiratory distress, and changes in mental status.
Question 2 of 5
The nurse is caring for a client receiving oxygen therapy via a nasal cannula. Which action by the nurse is appropriate when providing oral care to the client?
Correct Answer: A
Rationale: To ensure effective oral care, the nurse should temporarily remove the nasal cannula while performing oral care procedures. This allows better access to the client's mouth and prevents interference with oral hygiene.
Question 3 of 5
A nurse cares for a toddler who has a decreased appetite, an erratic eating pattern, and fussiness at mealtime. Which recommendation should be made to the parents?
Correct Answer: D
Rationale: Toddlers prefer the routine of consistent mealtimes. Frequent nutritious planned snacks can replace a meal, but shouldn’t replace a regular sit-down meal. Nibbling and snacking is a way to ensure proper nutrition when appropriate foods are offered. Nutritious snacks include several small pieces of food such as crackers, carrots, sliced cold meat, and raisins.
Question 4 of 5
A toddler is dehydrated as the result of complications from varicella-zoster virus. Fluid filled vesicles are observed on the face and chest. Which actions should the nurse implement? Select one that doesn't apply
Correct Answer: C
Rationale: 1. The nurse should place the client on airborne precautions. A private, negative air-flow room with at least six to twelve exchanges per hour is required. All health care personnel should wear an N95 respirator each time they enter the room. 2. The nurse should provide surgical masks for visitors. The nurse should also place a surgical mask on the client if transport outside of the private room is required. 4. The nurse should explain guidelines for contact precautions to the family. In addition to airborne precautions, standard and contact precautions should be maintained until lesions are dry and crusted. 5. A positive immune status must be confirmed. Evidence of immunity includes any of the following: documentation of age-appropriate varicella vaccination; laboratory evidence of immunity or confirmation of disease; diagnosis or verification of a history of varicella by a health care provider.
Question 5 of 5
A client who has severe burns is receiving total parenteral nutrition (TPN). Which lab value indicates therapeutic effectiveness of TPN?
Correct Answer: C
Rationale: A serum albumin of 4.0 is within normal and desired range (3.5 to $5.0 \mathrm{~g} / \mathrm{dL}$ ) and indicates a therapeutic effect of TPN. Nutritional requirements for a client with a severe burn can exceed 5,000 kcal/day. Enteral nutrition is preferred however if the client’s gastrointestinal tract is not functioning or when the nutritional needs cannot be met by oral and enteral feeding, TPN may be required.
