A patient with active TB continues to have positive sputum cultures after 6 months of treatment. She says she cannot remember to take the medication all the time. What is the best action for the nurse to take?

Correct Answer: D

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

Correct Answer: D

Rationale: The correct answer is D: Occupation and hobbies. This is the highest priority information for the nurse to obtain because it can provide crucial insights into potential respiratory risks or exposures (e.g., smoking, exposure to fumes or pollutants). Understanding the client's occupation and hobbies helps the nurse assess the impact on respiratory health and tailor interventions accordingly. A: Average daily fluid intake is important for overall health but not directly related to respiratory status. B: Neck circumference may be relevant for assessing airway patency in certain conditions, but occupation and hobbies are more pertinent. C: Height and weight are important for general health assessment but do not directly impact respiratory status as much as occupation and hobbies.

Correct Answer: C

Rationale: The correct answer is C: Cerebral hemispheres. The impulse for voluntary muscles for forceful breathing originates in the cerebral hemispheres where conscious control over breathing is regulated. The cerebral cortex sends signals to the respiratory muscles to increase or decrease breathing effort based on the body's needs. The other choices are incorrect because: A: Medulla (Pons) - This region of the brainstem is responsible for automatic breathing control, not voluntary forceful breathing. B: Vagus nerve - The vagus nerve is not directly involved in initiating voluntary breathing movements. D: Spinal cord - While the spinal cord plays a role in coordinating some aspects of breathing, it is not the primary center for voluntary forceful breathing control.

Correct Answer: C

Rationale: The correct answer is C: Erythropoietin. When climbing a mountain, the body experiences reduced oxygen levels, triggering the release of erythropoietin to stimulate red blood cell production and improve oxygen delivery. This helps counteract the effects of high altitude. Explanation of other choices: A: Anti Natriuretic Factor - This hormone regulates sodium and water balance in the body, not directly related to climbing a mountain. B: Adrenaline - Released in response to stress or danger, not specifically related to climbing a mountain. D: Thyroxine - Regulates metabolism and energy levels, not directly related to the physiological response to climbing a mountain.

Correct Answer: A

Rationale: The correct answer is A: Non-ciliated Squamous epithelium. The alveolar epithelium in the lungs is composed of thin, flat cells called squamous epithelium. This type of epithelium allows for efficient gas exchange by providing a short diffusion distance. Ciliated epithelium (choice C) and ciliated columnar epithelium (choice D) are not found in the alveoli as they are more suited for moving mucus and debris in the respiratory tract. Ciliated squamous epithelium (choice B) is not a common epithelial type in the alveoli and is not as thin as non-ciliated squamous epithelium, making it less efficient for gas exchange.
