Which type of drug–receptor interaction prevents the expected response produced by an endogenous agonist?

Forty minutes after paracentesis removing 5.5 L, the patient becomes dizzy at rest and nauseated. Orders: vitals every 15 minutes for 1 hour, strict I&O, albumin 25% IV now, PRN 500 mL normal saline if SBP < 90 mmHg. Trend vitals: 15 min BP 102/64 HR 96; 30 min BP 96/60 HR 106; 45 min BP 92/58 HR 112. Tap site shows a quarter-sized area of clear moisture without active leak. Which action should the nurse take first?

The blood–brain barrier limits drug entry primarily by:

Determine where the graph of is concave up and/or concave down, and also find any points of inflection, if they exist. Be sure to use the chart below that you printed out, and fill and fill in the information just like we did in the lectures. 

Which factor reduces oral drug absorption due to metabolism before reaching systemic circulation?

Which organ is the primary site of drug metabolism?

A patient is brought into the emergency department via EMS after an episode of near-syncope at home. On arrival the patient is pale and diaphoretic, complaining of lightheadedness and chest pressure. Vitals: BP 78/46 mm Hg, HR 32/min, RR 22/min, SpO2 95% on room air.  Answer in complete sentences: Using the strip and your assessment findings, classify the rhythm category and explain the underlying pathophysiology. Identify the top reversible etiologies you would prioritize ruling in or out and why. Detail your immediate nursing and medical management for the first 4 minutes, then the next phase of care. State whether defibrillation is indicated and justify your reasoning. Predict patient outcomes when a reversible cause is identified and treated promptly versus when no cause is found or treatment is delayed; support with physiologic reasoning.
