Acute Respiratory Care Nursing Questions Questions
Question 1 of 5
A nurse provides teaching to a client who is scheduled for a colonoscopy. Which statements should be included? Select one that doesn't apply.
Correct Answer: B
Rationale: 1. The client should consume a clear liquid diet the day before the colonoscopy and avoid red, orange, or purple (grape) beverages. 3. The client should avoid certain medications such as aspirin, anticoagulants and antiplatelet medications for several days prior to the procedure or as instructed by the provider. 4. Oral solutions can be chilled to help improve taste. Watery diarrhea usually begins an hour after administration. 5. Instruct the client to arrange for transportation home from the procedure. The client should be instructed not to drive or operate equipment for 12 to 18 hours after the colonoscopy.
Question 2 of 5
When planning care,for which client should the nurse include close observation for a decreased or absent cough reflex?
Correct Answer: B
Rationale: The cough reflex relies on vagus nerve (cranial nerve X) conduction to the medulla. Impairment of vagus nerve function (B) such as from spinal cord injury or CNS depression can decrease or eliminate the cough reflex increasing risks of aspiration and respiratory infections requiring close monitoring. Nasal fractures (A) and sinus infections (C) do not typically affect the cough reflex. Reduced respiratory membrane conduction (D) impacts gas exchange
Question 3 of 5
Upon assessment,the nurse notes that a client has dyspnea crackles in both lung bases and tires easily upon exertion. Which nursing diagnosis is best supported by these assessment details?
Correct Answer: C
Rationale: Crackles in both lung bases (C) indicate fluid or mucus in the airways supporting Ineffective Airway Clearance where the client struggles to clear secretions leading to dyspnea and fatigue. Ineffective Breathing Pattern (A) focuses on altered rhythm or depth not crackles. Anxiety (B) lacks specific respiratory findings. Impaired Gas Exchange (D) relates to oxygenation deficits not primarily airway clearance making C the best-supported diagnosis.
Question 4 of 5
The nurse needs to hyperinflate a client prior to suctioning. How should the nurse proceed with this requirement?
Correct Answer: C
Rationale: Hyperinflation before suctioning prevents hypoxia by delivering 2-3 breaths at 1.5 times the tidal volume (C) typically via a manual resuscitator or ventilator setting. Adjusting suction level (A) does not address oxygenation. Increasing oxygen flow (B) is insufficient for hyperinflation. Coughing (D) does not ensure adequate oxygenation making C the correct method to maintain oxygen levels during suctioning.
Question 5 of 5
The nurse who is performing care for a client with a new tracheostomy needs to change the ties. What is the best method for changing these ties?
Correct Answer: C
Rationale: Changing tracheostomy ties risks dislodgement requiring an assistant to hold the tube (C) while removing soiled ties and replacing them ensuring safety. Removing ties without assistance (A) is unsafe. Tying with a square knot (B) is correct but incomplete without assistance. Removing the outer cannula (D) is unnecessary and risky making C the best method for secure tie replacement.
