Acute Respiratory Care Nursing Questions Questions
Question 1 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 2 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 3 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.
Question 4 of 5
A client is experiencing atelectasis. The nurse anticipates that this client will have an alteration in
Correct Answer: A
Rationale: Atelectasis (collapsed alveoli) reduces lung compliance impairing ventilation (A) the movement of air into and out of the lungs. Alveolar gas exchange (B) is affected secondarily. Transportation (C) and systemic diffusion (D) are downstream processes not directly altered by atelectasis making A the primary alteration to anticipate.
Question 5 of 5
A client is diagnosed with congestive heart failure. The nurse should assess the client for which conditions that can alter this clients respiratory function?
Correct Answer: B
Rationale: Congestive heart failure (CHF) reduces cardiac output impairing oxygen transport (B) from lungs to tissues and $\mathrm{CO} 2$ return affecting respiratory function. Airway conditions (A) air movement (C) and diffusion (D) are less directly impacted by CHF making B the primary concern for assessing respiratory alterations.
