Final answer:
Ear muffs are not necessarily more comfortable than earplugs.
Step-by-step explanation:
False. Ear muffs may be more costly than earplugs, but they are not necessarily more comfortable for everyone. Respiratory syncytial virus (RSV) is typically diagnosed through a respiratory specimen, often obtained via a nasopharyngeal swab or nasal wash. However, it's important to note that the method of obtaining a sample (nasopharyngeal swab) is not used to make the diagnosis itself; rather, the collected sample is sent to a laboratory for testing, such as reverse transcription-polymerase chain reaction (RT-PCR), to confirm the presence of RSV. The diagnosis is based on laboratory results and clinical symptoms.
