Critical Care Respiratory Questions Questions
Question 1 of 5
A client has a medical condition that often results in the development of metabolic acidosis. The nurse should observe this client for the development of which breathing pattern as a result of this condition?
Correct Answer: D
Rationale: Metabolic acidosis triggers compensatory hyperventilation to reduce CO2 a process known as Kussmaul respirations (D) characterized by rapid deep breathing. Cheyne-Stokes (A) involves cycles of increasing and decreasing breathing seen in brain injury or heart failure. Biot's (B) features irregular shallow breaths associated with CNS disorders. Cluster (C) breathing involves bursts with pauses linked to brainstem issues. Thus D is correct for metabolic acidosis compensation.
Question 2 of 5
The nurse has just initiated oxygen by nasal cannula for a client with the medical diagnosis of chronic obstructive pulmonary disease. What is the nurses next action?
Correct Answer: B
Rationale: Padding the tubing at the ears (B) prevents pressure irritation enhancing comfort and compliance. Filling the humidifier (A) is important but not the immediate next step. Setting to 5 liters (C) risks CO2 retention in COPD and requires physician guidance. Ties (D) are not standard for nasal cannulas making B the correct next action for client comfort.
Question 3 of 5
A client who was a victim of a house fire is coughing. The nurse realizes that the purpose of the cough is to
Correct Answer: C
Rationale: Coughing removes irritants from the trachea and bronchi (C) where mucus traps particles and cilia sweep them upward. It does not primarily improve oxygenation (A) or involve nasal passages (B). Closing the glottis (D) is unrelated to cough function making C the correct purpose especially relevant after smoke inhalation.
Question 4 of 5
The nurse is assessing an older client. What effects of aging should the nurse keep in mind during this assessment?
Correct Answer: A
Rationale: E (Decreased cough reflex Dry mucous membranes Increased risk of aspiration) Aging reduces cough reflex (A) increasing aspiration risk (E) and dries mucous membranes (D) impairing airway clearance. Stiffening of blood vessels (B) affects cardiovascular health not respiratory. Altered protein synthesis (C) is nonspecific and unrelated making A
Question 5 of 5
The nurse is performing nasotracheal suctioning of a client. What should the nurse do when suctioning this client?
Correct Answer: A
Rationale: Nasotracheal suctioning should apply suction for 5-10 seconds (A) to minimize hypoxia and trauma with intermittent suctioning. Suctioning for 10 minutes (B) is excessive and dangerous. Applying suction during insertion (C) risks mucosal damage. 20-30 seconds (D) is too long increasing hypoxia risk making A the correct technique.
