A 66 year old with a history of hypertension, diabetes, end stage renal disease, and peripheral vascular disease presents after a car accident with a left pneumothorax, and in hypovolemic shock from multiple hemorrhaging sites. The patient is given 2L of lactated ringers to improve the blood pressure, until ordered blood products arrive. The patient’s blood pressure improves after the first liter, but does not respond to the second, so a Norepinephrine (Levophed) gtt is ordered. Given the information provided, which of the following accesses placed emergently would be most appropriate for a Levophed infusion?

A 38 year old with a history of ventricular dysrhythmias and a pacemaker presents with cardiogenic shock. In the past, he’s has dysrhythmias with drugs that stimulate beta 1 receptors. In report, the nurse learns the patient’s been going in an out of ventricular tachycardia in the ER. The physician decides to order a drug that will increase systemic vasoconstriction, but won’t act on the beta1 receptors to increase contractility. Which drug can he choose?

What internal data structure uses push and pop operations to manage method execution?

You’re writing your own programming language and are given three potential algorithms to pick from and implement as the built-in sorting method.  You’re expecting programmers to use the method to sort very large lists.  Out of selection, insertion, and merge sort, which would you pick. State your algorithm choice AND it’s time complexity in big O notation.

Write the name and return type of the abstract method that is declared in the Comparable interface.

A 78 year old male with shock secondary to MRSA bacteremia presents to the ICU from the ER with anaphylactic shock. He comes to the ICU on the maximum dose of a Levophed gtt, but his MAP is 49 mmHg (goal MAP 65-75 mmHg). His hemodynamics are the following: CI 3.2, SVI 57, SVRI 1320, and SVV 7. Based on the information provided, what should be the next intervention? Parameter Normal Range Cardiac Index 2.5-4.2 Stroke volume index 30-65 ml/beat/m2 Systemic vascular resistance index 1680-2580 dynes/sec/cm-5/m2 Stroke volume variation
