Introduction:
The electrocardiogram (ECG) is a process through which the electrical activity of the heart is recorded on a characteristic graph paper. The heart is myogenic, that means it consists of specific cardiac muscles that can generate electrical impulses on their own. The sinoatrial nodes are the pacemakers of the heart. The ECG records the electrical activity of the heart on a graphical paper where different tracings are present. The tracings correspond to the systole, diastole and other processes in the heart. The graphical representation has a characteristic amplitude, direction, and duration of the different tracings. The standard ECG uses a 12-lead system, which are the electrodes.

- During your 0800 – 1800 shift, Mr. Mamaril is under your care. You receive a medication order to administer 500.mL of 2/3 & 1/3 over 8.hours. You begin infusion at 0800 using a 500 mL IV bag, and a delivery set calibrated to.25 gtt/mL. At 1400, there is 240.mL TBA. b) Is the IV on time, ahead or behind, and by how much (mL)? c) What is the new flow rate (mL/hr)? d) What is the new drip rate (gtt/min)?arrow_forwardCase 2 Mr. PO is 72 years old, weighs 105 kg (231 lb), and measures 5 11 in. (71 in. [180 cm]). He was admitted to the hospital for the treatment of community-acquired pneumonia. His past medical history is positive for moderate heart failure. While in the hospital, Mr. PO develops atrial fibrillation, and the decision is made to treat him with digoxin to provide ventricular rate control. His serum creatinine concentration is 3.5 mg/dL and stable. Calculate an IV loading dose and intravenous maintenance dose that will achieve a Css of 1.5 ng/mL (mcg/L; 1.9 nmol/L). Case 2 follow-up Mr. PO does well on his intravenous digoxin regimen, his Css was 1.5 ng/mL. Mr. PO wants to go home, the MD asks you to convert his digoxin therapy to oral.arrow_forwardFor items 2-5, identify if the given situation exceeded the allowable blood loss (A) or the blood loss is within the safe volume (B). 2. In an accident, a 70kg man who is 175cm tall lost about 4 liters of blood. 3. A woman who is 35 and weighs 60kg and is 155cm tall donated 2 bags of 100cc blood. 4. A teenager lost 2L of blood. She is 168cm tall, 18 of age and 71kg. 5. A 65 years old man lost 3L of blood as he travelled to save himself towards the hospital. He is 183cm tall and weighs 78kg.arrow_forward
