.A nurse is assessing a client who is 12hr postoperative following a colon resection. Which of the following findings should the nurse report to the surgeon? 1. Heart rate 90/min 2. Absent bowel sounds → normal findings after major bowel surgery; takes several days to return to normal. 3. Hgb 8.2 g/dl 4. Gastric pH of 3.0 Rationale: Normal Hgb is 13-18M g/dl, 12-16 g/dl. This may indicate a possible hemorrhaging. 2. A nurse is caring for a client who has diabetes insipidus. Whic...

What are the 6 parts of the cardiac conduction cycle? correct answer: -SA node -Internodal pathways -AV node -Bundle of His -R and L bundle branches -Purkinje fibers What is the SA node? correct answer: -Small cluster of cells located in the upper R atrium *-Pacemaker of the heart* What are internodal pathways? correct answer: Impulses sent by the SA node that travel through the atrial muscle fibers via the intra-atrial pathways Allows for simultaneous depolarization and contra...

CRAT exam: ECG Interpretation7 steps, analyzing 12 lead ECG 1. Determine ECG rhythm or regularity 2. Determine atrial ventricular rate. 3. Identify a P-wave morphology. 4. Measure the PR interval. 5. Measure the QRS duration, analyze the morphology. 6. Evaluate the leads in groups. 7. Identify the morphological changes. 12 lead ECG reading BIG LIE, LITTLE LIE, SAY, ALL Big LIE I: lateral II: inferior III: inferior LITTLE LIE aVR: not used for MI interpretation. Useful for dex...

Automaticity correct answer: Ability to initiate an impulse at a regular interval; "pacemaker" Excitability correct answer: Ability of the heart to respond to a stimulus Conductivity correct answer: Ability of the heart to transmit an electrical impulse from one cell membrane to another Contractility correct answer: The ability of the heart muscle cells to shorten in response to an electrical stimulus Refractoriness correct answer: "Resistant to"; cannot respond to a stimulu...

P wave: PR interval: QRS complex: (ST segment) T wave: QT interval: correct answers • P wave - atrial depolarization and contraction • PR interval - time of travel from the SA node to AV node (.12-.2) • QRS - ventricular depolarization and contraction (.08-.12) - Note: Atrial repolarization occurs during this time, but cannot be seen on EKG • T wave - ventricular repolarization • QT interval - start of ventricular contraction to end of relaxation Systematic Approach to ana...

Which of the following are semilunar valves? correc...
