A nurse is caring for a client who has heart failure and respiratory arrest. What should be the nurse’s first action?
Auscultate for breath sounds.
Establish an open airway.
Establish IV access.
Feel for a carotid pulse.
The Correct Answer is B
Establishing an open airway is the most crucial and immediate action in any respiratory arrest situation, including when a client has heart failure. Here's a detailed explanation: 1. Airway patency is paramount for survival: Oxygen, the essential element for life, cannot reach the lungs and bloodstream without a clear and unobstructed airway. Brain cells are extremely sensitive to oxygen deprivation and start to die within minutes without it, leading to irreversible brain damage or death. 2. Respiratory arrest in heart failure: Heart failure often leads to fluid buildup in the lungs (pulmonary edema), which can significantly impair breathing. Respiratory arrest can occur due to: Excessive fluid accumulation in the lungs. Weakening of respiratory muscles due to fatigue or heart failure itself. Arrhythmias or heart blocks affecting heart's ability to pump effectively. 3. Steps to establish an open airway: Head tilt-chin lift maneuver: Gently tilt the head back and lift the chin to open the airway. Jaw thrust maneuver: If a neck injury is suspected, use the jaw thrust maneuver to avoid further injury. Removal of any visible obstructions: Clear any visible foreign objects or fluids from the mouth or throat. Use of airway adjuncts: Consider using oral or nasal airways to maintain airway patency, especially if the patient is unconscious.
4. Rationale for other choices:
A. Auscultating for breath sounds: While important for assessment, it does not address the immediate need to establish airflow.
C. Establishing IV access: IV access is necessary for medications and fluids, but airway takes priority in respiratory arrest.
D. Feeling for a carotid pulse: Checking for a pulse is essential, but only after ensuring an open airway and attempting to restore breathing.
5. Importance of prioritizing airway: Establishing an open airway allows for potential rescue breaths and ventilation, which can help restore oxygen levels and prevent further deterioration. Even if a pulse is present, without a clear airway, oxygen cannot reach the vital organs, leading to organ failure and death.

Correct Answer is D
Explanation
Choice A rationale:
Respiratory acidosis is characterized by a low pH (less than 7.35), a high PaCO2 (greater than 45 mm Hg), and a normal or high HCO3 (22-26 mEq/L). It occurs when there is a buildup of carbon dioxide in the blood due to impaired ventilation.
The patient's ABGs do not align with respiratory acidosis because the pH is elevated (7.6), and the PaCO2 is within the normal range (40 mm Hg).
Choice B rationale:
Respiratory alkalosis is characterized by a high pH (greater than 7.45), a low PaCO2 (less than 35 mm Hg), and a normal or low HCO3 (22-26 mEq/L). It occurs when there is excessive loss of carbon dioxide through hyperventilation.
The patient's ABGs do not align with respiratory alkalosis because the HCO3 is elevated (32 mEq/L), which is not typical for this condition.
Choice C rationale:
Metabolic acidosis is characterized by a low pH (less than 7.35), a normal or low PaCO2 (less than 40 mm Hg), and a low HCO3 (less than 22 mEq/L). It occurs when there is an excess of acid in the body or a loss of bicarbonate.
The patient's ABGs do not align with metabolic acidosis because the pH is elevated (7.6), and the HCO3 is elevated (32 mEq/L).
Choice D rationale:
Metabolic alkalosis is characterized by a high pH (greater than 7.45), a normal or high PaCO2 (40-45 mm Hg), and an elevated HCO3 (greater than 26 mEq/L). It occurs when there is an excess of bicarbonate in the body or a loss of acid.
The patient's ABGs align with metabolic alkalosis because of the high pH (7.6), normal PaCO2 (40 mm Hg), and elevated HCO3 (32 mEq/L).
Correct Answer is C
Explanation
Choice A rationale:
A colostomy is a surgical procedure that creates an opening in the colon (large intestine) to divert stool through the abdomen. While a colostomy can affect bowel function, it does not directly increase the risk of aspiration. This is because the colon is located further down the digestive tract and does not directly involve the airway.
Choice B rationale:
An ileostomy is a surgical procedure that creates an opening in the ileum (small intestine) to divert stool through the abdomen. Similar to a colostomy, an ileostomy does not directly increase the risk of aspiration because the ileum is also located further down the digestive tract and does not involve the airway.
Choice C rationale:
Enteral feedings, also known as tube feedings, involve delivering nutrients directly into the stomach or small intestine through a tube. Patients receiving enteral feedings through a nasogastric (NG) tube are at a significantly higher risk of aspiration for several reasons:
Impaired swallowing mechanisms: Many patients who require enteral feedings have impaired swallowing mechanisms, which can increase the risk of food or liquid entering the airway instead of the esophagus.
Tube placement: The NG tube itself can potentially irritate the esophagus or interfere with the normal closure of the upper esophageal sphincter, which can increase the risk of reflux and aspiration.
Feeding formula: Enteral feeding formulas are often thin and liquid-like, which can make them easier to aspirate than thicker liquids or solid foods.
Positioning: Patients receiving enteral feedings are often in a reclined position, which can make it easier for fluids to travel back up the esophagus and into the airway.
Choice D rationale:
A chest tube is a drainage tube inserted into the chest cavity to remove air or fluid. While a chest tube can affect respiratory function, it does not directly increase the risk of aspiration. This is because the chest tube drains fluid from the pleural space, which surrounds the lungs, and does not directly involve the airway or digestive tract.
