When interpreting a chest film, how many rib pairs should be counted:

What is the normal relationship between the OFC and chest circumference:

Note: Same information for questions 20-25. The world is made of two countries. Home has 8000 workers and Foreign has 2000 workers. One unit of labor is one worker working for a week. The following figure represents the marginal product of labor of the home country (MPL, measured from the left) and the marginal product of labor of the foreign country (MP*L, measured from the right). Note: it’s really important that you get the initial situation (before there is any migration) correctly. If you get it wrong all of your answers are likely to be wrong. Migration between the two countries is strictly forbidden. Use this to answer questions 20-21. How much is the weekly real wage in Home? Enter a whole number.

A high pitched, hoarse, upper airway noise resembles: 

Tachypnea persisting longer than this many hour(s) is an indication of underlying lung pathology: 

Note: Same information for questions 5-19, except where noted. The world is composed of two countries, Country A and Country B. They use labor to produce two goods, Coats and Umbrellas. All of the assumptions of the Ricardian Model hold. The following table shows the unit labor inputs to make each good in each country. One unit of labor is one hour of labor. Country A has 6000 units of labor and country B has 10000 units of labor. The two countries are engaged in free and costless trade and both countries gain with trade, except as noted.   Unit Labor Inputs Good Country A Country B Coats       1      3 Umbrellas       4      24   The following graph represents the relative supply curve of umbrellas relative to coats and the relative demand of umbrellas relative to coats, for the two countries. It is not necessarily drawn in scale, it is for illustration only. Don’t use its scale to answer any questions. Use it as an illustration to answer questions 16-19 only. Notation: QUA means country A’s supply or demand of Umbrellas, and analogously for the other symbols. (Note: Having separate information is to your advantage, as it decouples the answer here from other answers that you may have gotten wrong. However, don’t use this information to answer any other questions, as the information here is not necessarily correct for other questions!) Enter the number Z in the figure above, or enter 0 if not enough information is provided. Round to the nearest 0.01.

Are the following two statements true or false? Interpersonal and organizational CWBs are weakly correlated. There is no benefit to conceptualizing CWBs as specific behaviors.

A 9-year-old refuses to sleep alone, becomes physically distressed when the parent leaves for work, and reports nightmares about losing family members. Symptoms have persisted for 6 weeks and impair school attendance. What is the most likely diagnosis? 

A 7-year-old was involved in a severe car accident. One month later, they exhibit repetitive play reenacting the crash, nighttime regression, and clinginess. There are no intrusive verbal memories reported. What diagnosis best fits? 

A 15-year-old presents with severe irritability, pressured speech, decreased need for sleep, and increased goal-directed activity lasting 7 days. No substance use is reported. Which diagnosis is MOST consistent with this presentation?
