Critical Care Respiratory Questions Questions
Question 1 of 5
A client with anemia presents with fatigue and decreased exercise tolerance. What is the primary indication for initiating oxygen therapy in this client?
Correct Answer: A
Rationale: In a client with anemia, the primary indication for oxygen therapy is to increase the oxygen-carrying capacity of the blood and improve tissue oxygenation.
Question 2 of 5
A nurse is caring for a client receiving high-flow oxygen therapy via a noninvasive positive pressure ventilation (NPPV) device. What is an important nursing intervention for this client?
Correct Answer: C
Rationale: NPPV devices, such as continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BIPAP), can cause dry mouth. Providing frequent oral care, such as mouth rinses and moisturizing agents, helps alleviate discomfort and prevent oral complications.
Question 3 of 5
Which statement by a client on oxygen therapy indicates the need for further education?
Correct Answer: B
Rationale: Securing the oxygen tubing under furniture legs can create a potential safety hazard by causing the tubing to become twisted or pulled, disrupting the oxygen flow. It is important to educate the client about keeping the tubing free from obstructions and ensuring it is positioned safely.
Question 4 of 5
The nurse is caring for a client with a tracheostomy receiving oxygen therapy. Which intervention should the nurse prioritize to prevent infection and ensure proper oxygen delivery?
Correct Answer: C
Rationale: Applying a sterile dressing over the tracheostomy site helps prevent infection by providing a barrier against microorganisms. It also ensures a clean environment for optimal oxygen delivery and promotes wound healing.
Question 5 of 5
A client who has endometrial cancer is receiving sealed internal radiation therapy. Which actions should the nurse implement? Select one that doesn't apply.
Correct Answer: C
Rationale: 1. Wearing a lead apron when providing care is recommended to protect the caregiver from radiation exposure. Always keep the front of the apron facing the client and do not turn so that the back of the caregiver is facing the client. 5. Women who are pregnant (including caregivers) should not enter the room. In addition, if the caregiver is attempting to conceive, whether they are male or female, they should not perform direct client care. Children younger than 16 should not be allowed to visit either. A 'Caution: Radioactive Material' sign should be placed on the door to the client’s room.
