Fundamentals of Nursing Oxygenation Practice Questions Questions
Question 1 of 5
A nurse provides care for a client who reports sudden onset of sweating, shortness of breath, dizziness, and pounding heart. Which ABG value should be expected?
Correct Answer: B
Rationale: The client is reporting symptoms characteristic of an acute attack. This ABG value represents respiratory alkalosis (↑pH, ↓PaCO₂) which can result from excessive loss of carbon dioxide. Examples of conditions that can cause this include: hyperventilation, anxiety, fear, mechanical ventilation, high altitudes, salicylate toxicity, and early stages of shock and acute pulmonary problems.
Question 2 of 5
A home health nurse is discussing the dangers of carbon monoxide poisoning with a client. Which of the following information should the nurse include?
Correct Answer: C
Rationale: Carbon monoxide (CO) is odorless and colorless (A is incorrect). Water heater inspections (B) are relevant but not the primary focus. CO damages tissues by binding to hemoglobin (D) forming carboxyhemoglobin which impairs oxygen delivery and can harm organs like the lungs (C). Thus C and D are correct to educate the client on CO's effects and risks.
Question 3 of 5
After learning of a terminal illness and life expectancy,the client begins to hyperventilate and complains of being light-headed with the fingers toes and mouth tingling. What action should be taken by the nurse?
Correct Answer: B
Rationale: The client's symptoms (light-headedness tingling) indicate hyperventilation likely due to anxiety causing respiratory alkalosis. Slowing respirations (B) by counting or matching the nurse's slower rate corrects CO2 levels alleviating symptoms. Resuscitation (A) is unnecessary as this is not cardiac arrest. Trendelenburg and coughing (C) are inappropriate and could worsen symptoms. Meperidine (D) is for pain not hyperventilation making B the correct action. not cough reflex making B correct.
Question 4 of 5
A client is receiving oxygen by nonrebreather mask,but the bag is deflating on inspiration. What action should be taken by the nurse?
Correct Answer: D
Rationale: A nonrebreather mask bag deflating on inspiration indicates insufficient oxygen flow risking CO2 buildup. Increasing liter flow (D) ensures the bag remains inflated delivering adequate oxygen. Turning to the left side (A) is unrelated. Increasing oxygen percentage (B) is not adjustable on standard nonrebreathers. Checking the seal (C) is important but does not address flow issues making D the correct action.
Question 5 of 5
The nurse has completed discharge teaching for a client who will be going home on oxygen therapy. What statement made by the client would indicate that this client needs further instruction?
Correct Answer: A
Rationale: Polyester blankets (A) produce static electricity increasing fire risk with oxygen indicating a need for further instruction. Prohibiting smoking (B) checking grounding (C) and having a fire extinguisher (D) are correct safety measures. Thus A is incorrect as cotton or wool is safer to avoid static sparks in an oxygen-rich environment.
