PALS EXAM I 2023 VERFIED QUESTIONS AND ANSWERS ALREADY PASSED

Primary utilizations of laboratory tests for pharmacists: - CORRECT ANS -Health screenings -Monitoring of drug therapy -Evaluation of clinical course of a disease -NOT FOR DIAGNOSIS Potassium - CORRECT ANS Plays a key role in: -Regulation of nerve excitability -Acid base balance -Muscle function Cardiac function and neuromuscular function can be significantly affected by either an increase or decrease in potassium levels. Basic Metabolic Panel - CORRECT ANS Provides information about the current health of your kidneys and respiratory system as well as electrolyte, acid/base balance, and glucose levels. When is it used? For diagnosis of a problem affecting kidneys, electrolyte imbalance, or acid base imbalance. Can be helpful when someone has general symptoms like fatigue, confusion, prolonged vomiting or breathing problems. Sodium (Na+): 135-147 mEq/L Potassium (K+): 3.5-5.0 mEq/L Chloride (Cl-): 95-105 mEq/L CO2 content (Bicarbonate - HCO3): 22-28 mEq/L Serum Creatinine (SCr): 0.6-1.2 mg/dL Blood Urea Nitrogen (BUN): 6-20 mEq/L Glucose (Glu): 70-99 mg/dL Sodium - CORRECT ANS Important in regulating: -serum osmolality -fluid balance -acid-base balance In addition, sodium also assists in maintaining the electric potential necessary for transmission of nerve impulses. Chloride - CORRECT ANS Passive role in the maintenance of fluid balance and acid-base balance. Serum chloride values are useful in identifying fluid or acid-base balance disorders. Bicarbonate (HCO3) - CORRECT ANS CO2 content is composed mostly of bicarbonate and is a base. CO2 content is regulated by the kidneys. Glucose - CORRECT ANS Important energy source for most cellular functions Blood Urea Nitrogen - CORRECT ANS End product of protein catabolism. It is produced in the liver, transported in the blood, and cleared by the kidneys. BUN concentration serves as a marker of renal function. Comprehensive Metabolic Panel - CORRECT ANS Includes all of the BMP components along with the addition of the health of your liver and important blood proteins. When is it used? Often used to evaluate liver function, kidney function, and nutrient levels. Offers a broad loo at different functions of the body. Electrolyte panel - CORRECT ANS Helpful for detecting a problem with the body's fluid and electrolyte bal
