Fundamentals of Nursing Oxygenation Practice Questions Questions
Question 1 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 2 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.
Question 3 of 5
A client who is being mechanically ventilated has copious amounts of secretions ranging from thick and tenacious to frothy. In preparing to suction this client,the nurse should take which action?
Correct Answer: D
Rationale: Hyperventilation (A B) risks pushing secretions deeper worsening obstruction. Instilling saline (C) is not recommended as it can increase infection risk. Increasing oxygen to $100 \%$ for several breaths (D) pre-oxygenates the client preventing hypoxia during suctioning making D the safest and most effective preparation.
Question 4 of 5
A clients blood gas results reveal a low oxygen level. The nurse realizes that which area of the body will respond to this level and influence respirations?
Correct Answer: D
Rationale: Low oxygen (hypoxemia) stimulates carotid bodies (D) located at the carotid artery bifurcation and aortic bodies which signal the respiratory center to increase ventilation. Alveoli (A) trachea (B) and bronchioles (C) do not directly sense oxygen levels making D the correct area influencing respiratory response to hypoxia.
Question 5 of 5
Which client statement indicates to the nurse that instruction about the use of a humidifier has been effective?
Correct Answer: C
Rationale: Humidifiers add moisture to prevent drying of mucous membranes and loosen secretions (C) indicating effective instruction. They do not remove moisture (A) or tighten secretions (B). They do not replace oxygen (D) making C the correct understanding of humidifier purpose.
