Air bubbles, if present in an arterial blood sample while patient breathing room air, will result: I. increase PaO2 II. decrease PaO2 III. increase PaCO2 IV. decrease PaCO2 V. increase pH

Think up and give a high-level overview of a longitudinal study that involves two variables (at least one self-report variable) you could conduct. Include the following details How you would get an unbiased sample (either name the type of sampling you would use or describe it) What type(s) of survey questions would you like to ask them and why (no need to list actual questions, just state what type(s)) Describe what correlations you would hypothesize you would see in your results (i.e. positive, negative, zero, weak correlation, moderate correlation, strong correlation)
