Chemical receptors that stimulate inspiration are located in the

Correct Answer: A

Rationale: The correct answer is A: Brain. Chemical receptors that stimulate inspiration are located in the brain, specifically in the medulla oblongata and pons in the brainstem. These receptors detect changes in blood gas levels, primarily an increase in CO2 levels, triggering the breathing response to inhale more oxygen and exhale CO2. The brain sends signals to the respiratory muscles to initiate inspiration. Summary of other choices: B: Lungs - While the lungs are responsible for gas exchange, they do not contain chemical receptors that directly stimulate inspiration. C: Aorta - The aorta is a large blood vessel that carries oxygenated blood from the heart, it does not contain receptors that regulate breathing. D: Stomach - The stomach is involved in digestion and has no role in regulating respiration.

Correct Answer: C

Rationale: The correct answer is C: Arterial blood gas levels. Monitoring arterial blood gas levels is crucial in assessing the client's oxygenation and ventilation status, which are directly affected by mechanical ventilation. It provides important information about the client's acid-base balance and respiratory function. This assessment helps the nurse make timely interventions to optimize ventilation support. Choice A: Skin integrity is important but not the priority when the client's respiratory status is unstable. Choice B: Blood pressure is important but not as critical as assessing oxygenation and ventilation status in a client on mechanical ventilation. Choice D: Fluid balance is important, but monitoring arterial blood gas levels takes precedence in this scenario as it directly reflects the effectiveness of mechanical ventilation.

Correct Answer: C

Rationale: The correct answer is C: Administer oxygen via nasal cannula. Oxygen therapy is the priority action for a patient with suspected pulmonary embolism to improve oxygenation and decrease the workload on the heart. This helps in maintaining adequate oxygen levels and preventing hypoxia. Administering a bronchodilator (choice A) is not the priority as pulmonary embolism is not primarily a result of bronchoconstriction. Placing the patient in high Fowler's position (choice B) may help with breathing but is not as crucial as providing oxygen therapy. Preparing the patient for a chest X-ray (choice D) may be necessary for further evaluation, but oxygen therapy takes precedence in managing the acute respiratory distress associated with pulmonary embolism.

Correct Answer: A

Rationale: The correct answer is A: Daytime sleepiness and snoring. Daytime sleepiness is a common symptom of obstructive sleep apnea due to disrupted sleep patterns. Snoring is also a typical sign as it indicates airway obstruction during sleep. Morning headaches and blurred vision (choice B) can be associated with sleep apnea but are not specific. Intermittent chest pain at night (choice C) is more indicative of other conditions like acid reflux or heart issues. Difficulty falling asleep (choice D) is not a classic symptom of obstructive sleep apnea.

Correct Answer: C

Rationale: The correct answer is C: "I need to schedule regular follow-up sputum tests." This is correct because regular sputum tests are necessary to monitor the effectiveness of TB treatment and to ensure the disease is not spreading. Choice A is incorrect as masks are not generally needed at home. Choice B is wrong because stopping medication early can lead to drug resistance. Choice D is inaccurate as spicy foods do not affect TB treatment. Regular sputum tests are essential for monitoring progress and adjusting treatment if needed.
