What have you learned about ventilation?

A. Stable angina: This type of angina typically occurs with physical activity or stress and is relieved by rest or the use of nitroglycerin. The patient's report of chest pain occurring with activity, subsiding after taking nitroglycerin, and lasting for 8 minutes aligns with the characteristics of stable angina, indicating that the heart is not receiving enough oxygen during increased demand.

B. Variant angina (Prinzmetal angina): This type of angina occurs due to coronary artery spasms and can happen at rest, often without any apparent trigger. It is usually relieved by rest or medication but is less likely to be activity-related, making it an unlikely diagnosis in this case.

C. Microvascular angina: This type of angina is associated with dysfunction of the small coronary arteries rather than blockages in the larger arteries. It may present differently and is often not directly linked to physical activity or relieved by nitroglycerin.

D. Unstable angina: Unstable angina is characterized by unexpected chest pain that occurs at rest, is more intense, and lasts longer than stable angina. It does not typically resolve quickly with nitroglycerin. Since the patient reports that the pain was activity-related and resolved after taking nitroglycerin, unstable angina is unlikely in this scenario.

A. A woman presenting with malaise, lethargy, and copious nasal secretions: These symptoms are more indicative of a common cold or viral upper respiratory infection. While nasal secretions can occur in rhinosinusitis, the absence of facial pain or pressure suggests a cold rather than sinus involvement.

B. A man with a dry, stuffy nasopharynx, a sore throat, and temperature of 98.9°F: This presentation is typical of a common cold or upper respiratory infection. The symptoms of a dry, stuffy nasopharynx and sore throat are not specifically indicative of rhinosinusitis, which usually involves more pronounced nasal and facial symptoms.

C. A man complaining of general fatigue, a headache, and facial pain with a temperature of 100.9°F: This combination of symptoms strongly suggests rhinosinusitis. The presence of facial pain, headache, and fever indicates inflammation and infection of the sinuses, which is characteristic of rhinosinusitis rather than a common cold.

D. A woman complaining of generalized aches and who has a hoarse voice and reddened, painful upper airways: These symptoms align more closely with a viral upper respiratory infection or laryngitis. The absence of specific sinus-related symptoms such as facial pain or nasal obstruction makes rhinosinusitis less likely in this case.
