The Robust n. Archopallium (RA) area of bird brains is roughly equivalent to primary motor cortex in humans.  It receives inputs from the HVC and the lateral magnocellular nucleus of the anterior neostriatum (LMAN) that contribute to distinct aspects of song production. Consider the contributions of these inputs to RA activity and singing behavior by addressing the following questions: (5 pts) How is birdsong encoded by the activity of individual neurons in RA? How would inactivation or damage to RA affect a bird’s ability to learn or generate a good song? (5 pts) What are the behavioral effects of silencing/inhibiting LMAN in juvenile birds, and what does this suggest about the role of LMAN inputs to RA? What would you expect to be happening to the activity of RA neurons during song when LMAN is silenced, and why? (5 pts) What are the behavioral effects of slowing down (via cooling) activity in HVC in adult birds, and what does this suggest about the role of HVC inputs to RA? What would you expect to happen to the activity of RA neurons during song when HVC is cooled, and why? (5 pts) What are the behavioral effects of inhibiting activity (via GABA receptor agonism) in HVC in adult birds, and what does this suggest about the role of HVC inputs to RA? What would you expect to happen to the activity of RA neurons during song when HVC is inhibited, and why?

The nurse is doing an assessment on a newborn and finds a red rash with white papules and red macules all over the body, especially on the trunk. The nurse documents this finding as:

A nurse is providing care to the mother of a newborn that has intrauterine growth restriction (IUGR). Which of the following should the nurse include as a possible cause of this condition?

Which phase of wound healing involves clot formation?

Which patient requires contact isolation?

You are going to run an experiment that has four factors at three levels. How many runs will be necessary?

A nurse is reviewing the cardiovascular changes that occur at birth. Which sequence BEST describes the events leading to functional closure of the foramen ovale?

A nurse is assessing a hospitalized patient for risk of impaired tissue integrity. Which findings increase this patient’s risk? Select all that apply.
