Med-Surg (Exam One) Study Guide Final
Med-Surg Exam One A+
Study Guide (Fox)
What to Know For Exams:
● Test Yourself NCLEX Examination Challenge
● Know Nursing Safety Priority QSEN for the chapters (starts after multiple choice
study guides-below)
● Know the type of IV to infuse for a patient with hypovolemia (in chart and in
youtube link)
● The RN should assess patient manifestations for what in the patient with fluid
volume deficit?
○ Loss of extracellular fluid volume exceeds intake of fluid
○ This is not dehydration
○ Urine output <30 mL/hr

○ Acute daily loss of 1 pound
○ Monitor fluid overload: shoes, belt, abdominal girth
○ Weak, rapid pulse, and postural hypotension
○ Tissue turgor decreased (not accurate in elderly)
○ Urine specific gravity: >1.020
○ Increased BUN
○ Increased creatinine (normal = 0.7-1.4) better indicator of renal function than
BUN
● The highest priority nursing for a patient with a serum potassium level of 2.2 mEq/L
(Initiate cardiac monitoring)
● RN Pharmacology for Nursing ATI book (Chapter 27) will be on exam
● RN Medical Surgical Nursing will be on Exam 1 (2 ATI Chapters to study, BOTH are
Chapter 27 but 2 ATI books=Pharmacology and Med-Surg, also see the beginning of
each powerpoint for information to review for exams)

TACO (transfusion associated circulatory overload) TRALI (transfusion related acute lung injury)
What Is It? What Is It?
-Hydrostatic pulmonary edema due to transfusion -Acute respiratory distress
(too much blood and non-sanguineous fluid,
transfused too rapidly):
-High rates of volume infusion
-Underlying cardiac or pulmonary pathology
Risk Factors: Risk Factors:
● Very young/old ● Onset: within 6 hours of a plasma
● Onset: <2 hours of transfusion containing transfusion
Signs: Signs:
● Increased BP ● Fever (1-2 degrees)
● Tachycardia ● Hypotension (DO NOT GIVE
● Gallop, JVD, systolic/diastolic HTN DIURETICS-COULD WORSEN)
● Pulmonary edema ● Hypoxemia (oxygen sat <90% on room air)
● Increased BNP ● Bilateral pulmonary edema (rapid onset)
● No evidence of circulatory overload
● May be accompanied by:
-Fever, hypothermia, BP instability
Diagnosis: Diagnosis:
● EKG-new ST segment and T wave changes ● Bilateral infiltrates on chest X-ray
● Lab-troponin T >0.1 ng.mL
● Hemodynamic-PAOP >18 mmHg, CVP (central
venous pressure) >12
Treatment: Treatment:
● Diuretics ● Aggressive respiratory support
● Inotropic agents ● Mechanical ventilation
● Supplemental oxygen therapy ● Applying restrictive tidal volume
● Nitrates ● Fluid restriction
Role of BNP:
● Neurohormone released from ventricular
myocardium in response to ventricular
volume
● First introduced to diagnose CHF
Summary:
● Associated with significant morbidity
● “New” complication of importance
