The answer is B: Transport to a tertiary care center.

Explanation for each option:

A. Mechanical ventilation in a long-term care facility: This situation typically requires more permanent and efficient humidification systems than a heat moisture exchanger (HME), such as heated humidifiers, because patients are on long-term ventilation.

B. Transport to a tertiary care center: HMEs are often used during transport because they are portable, easy to use, and provide adequate humidification for short-term situations. They are suitable for temporary use when moving patients between facilities.

C. Patient with tenacious secretions: HMEs are not ideal for patients with thick or tenacious secretions because they can increase airway resistance and become clogged, leading to inadequate humidification and potential complications.

D. Delivery of aerosolized bronchodilators: HMEs are not suitable for use with aerosolized medications because they can trap the medication, reducing its delivery to the patient. A different humidification method should be used in conjunction with aerosol therapy.

In summary, HMEs are best suited for short-term use, such as during patient transport, making option B the correct choice.

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 70 miles per hour, with a standard deviation of 4 miles per hour. Estimate the percent of vehicles whose speeds are between 66 miles per hour and 74 miles per hour. (Assume the data set has a bell-shaped distribution.) Approximately % of vehicles travel between 66 miles per hour and 74 miles per hour.

At t=0 s, the number of Y particles is the number of A particles. At t=60 s, the number of the Z particles is the number of B particles. Therefore, the number of Y particles turned into Z particles is the number of A particles turned to B particles for the same amount of time. Therefore, the rate of reaction Y → Z is the rate of the reaction A → B.
