The nursing assistant tells you that the client on oxygen at a flow rate of 6 L/min by nasal cannula is complaining of nasal passage discomfort. What intervention should you suggest to improve the client's comfort for this problem?

Correct Answer: A

Rationale: The correct answer is A. Humidifying oxygen reduces nasal dryness and irritation caused by high-flow oxygen through a nasal cannula. Using a face mask (B) might help but is less practical for long-term use. Providing an extra pillow (C) or sitting up in a chair (D) does not address the nasal discomfort directly.

Correct Answer: D

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: D

Rationale: The correct answer is D because tracheal deviation indicates a potential pneumothorax, a life-threatening complication of thoracentesis. Trachea should be midline. A, B, and C are incorrect because mild pain, small drainage, and slightly decreased oxygen saturation are expected findings post-thoracentesis and do not necessitate immediate action.

Correct Answer: A

Rationale: Pulmonary ventilation is the total volume of air moved in and out of the lungs per minute. It is calculated by multiplying tidal volume (amount of air inhaled or exhaled in one breath) by respiratory rate (number of breaths per minute). Therefore, the correct answer is A: Tidal volume + Respiratory rate. Choice B (Tidal volume + Vital capacity) is incorrect because vital capacity is the maximum amount of air that can be exhaled after a maximum inhalation, not a component of pulmonary ventilation. Choice C (Tidal volume + Residual volume) is incorrect because residual volume is the volume of air remaining in the lungs after a maximal exhalation and is not involved in ventilation. Choice D (Tidal volume + Inspiratory reserve volume) is incorrect because inspiratory reserve volume is the additional air that can be inhaled after a normal inhalation and is not part of pulmonary ventilation calculation.

Correct Answer: B

Rationale: The correct answer is A: Contact. Bovine tuberculosis is primarily transmitted through direct contact with infected cows, such as through inhalation of respiratory droplets or consumption of contaminated milk. It is less commonly transmitted through consumption of infected meat or contamination of water with infected urine. Contact with infected animals poses the highest risk for transmission due to the bacterium Mycobacterium bovis being present in respiratory secretions and excretions of infected cows.
