Correct Answer: B

Rationale: Tidal volume is the amount of air delivered with each breath during mechanical ventilation. A common formula used to calculate tidal volume is 6-8 mL/kg of ideal body weight. For a client with an ideal weight of 60 kg, the expected tidal volume would be 60 kg x 6-8 mL/kg = 360-480 mL. Therefore, the most appropriate choice is 480 mL (Option B), which falls within the expected range based on the client's weight.

Correct Answer: A

Rationale: When a client reports headache and vertigo after turning on the furnace for the first time, it suggests carbon monoxide poisoning. Carbon monoxide is an odorless, colorless gas that can be released by malfunctioning heating systems. Symptoms of carbon monoxide poisoning include headache, dizziness, weakness, nausea, and confusion. It is crucial for the nurse to suspect this condition promptly to ensure the client's safety and well-being.

Correct Answer: A

Rationale: Respiratory acidosis is a condition characterized by increased carbon dioxide levels in the blood, resulting in acidosis. One of the potential consequences of respiratory acidosis is the development of electrolyte imbalances, particularly hyperkalemia. Hyperkalemia can lead to cardiac conduction abnormalities, manifested as widened QRS complexes on an electrocardiogram (ECG). Therefore, in a client with respiratory acidosis, the healthcare professional should expect to find widened QRS complexes as a result of the associated hyperkalemia.

Correct Answer: B

Rationale: When encountering a choking individual, the nurse should first assess the person's ability to speak. If the person can speak, it indicates that their airway is partially obstructed, allowing some air to pass. In this case, encouraging the person to continue coughing and monitoring them closely may be appropriate. If the person cannot speak, it may suggest a complete airway obstruction and immediate intervention is required. Instructing the person to call 911 (Choice A) may be necessary if the situation worsens. Using the jaw-thrust maneuver (Choice C) is not appropriate for a choking victim. Performing abdominal thrusts (Choice D) is typically recommended for conscious choking victims, not chest compressions.

Correct Answer: C

Rationale: Following a bronchoscopy, the priority for the nurse is to confirm the gag reflex in the older adult client. This is crucial to ensure that the client's airway is protected and free from any obstruction or aspiration. Monitoring the gag reflex helps in preventing complications such as aspiration pneumonia. While auscultating breath sounds, observing for confusion, and measuring blood pressure are important assessments, confirming the gag reflex takes precedence in this situation to maintain airway patency and prevent potential respiratory complications.
