NUR 317 - Cardiac Exam Study Guide Define the following terms. Describe patient symptoms and conditions that could cause alterations in: Cardiac Output Volume of blood flowing through systemic or pulmonary circuit expressed in liters per min Normal= 5 L/min (resting adult) HRXSV= CO Factors: preload‚ afterload‚ myocardial contractility‚ heart rate As heart rate increases‚ this allows less time for diastole and the heart often cannot fill adequately. Therefore‚ a very rapid heart will often have

1. What do those numbers (130/87) mean? What do they relate to in the cardiac cycle? The numbers 130/87 is the blood pressure of the patient. The top number 130‚ is the reading that is received when the heart is in contraction and blood is pushed out of the heart into the rest of the body (this is called systole). The bottom number 87‚ is the reading when the heart is at it relaxed state and is being refilled with blood (this is called diastole.) 2. This deposition of platelets and fibrin can

Variable: EDV‚ ESV‚ and cardiac cycle length 2. Independent Variable: level of physical activity 3. Controlled Variables: age‚ weight‚ height 4. What instrument was used to measure cardiac volumes? MRI 5. Does the instrument that was used to measure cardiac volume use X-rays? Explain. No. MRI uses a powerful magnet in conjunction with radio frequency waves to generate images of your internal organs and structures. .

Outline the differences between the excitation-contraction coupling mechanism between skeletal and cardiac muscles. Excitation-contraction coupling is the combination of the electrical and mechanical events in the muscle fibres and is related by the release of calcium from the sarcoplasmic reticulum. (Silverthorn‚ 2007) In the skeletal muscle‚ action potential in the nerves is generated when the somatic motor neurons releases the neurotransmitter acetylcholine (ACh)‚ at the neuromuscular junction

The mechanism of heart contraction and relaxation (mechanical restitution) is the basic of cardiac functioning. This mechanical restitution is driven by calcium movement and concentrations. An increase in cystolic calcium concentration causes contraction in myocardium. Calcium from the extracellular fluid enters the cardiomyocyte through the L-type Ca2+ channels after being propagated by the cardiac action potential which depolarises the cell. This flood of calcium triggers more calcium release

(1985) also correlated the ventricle dimension in elasmobranchs to endothermy and exothermy. Measurement of morphological characteristics enable us to estimate the cardiac output (Q) that increase linearly with body mass (Hughes‚ 1977). Comparative and scaling aspect of heart and body weight with reference to blood supply of cardiac fibres was studied by Poupa and Lindstrom‚ 1983. A large number of data of body weight and heart weight of several species from fish to mammals was collected by Crile

Reflective Essay The aim of this essay is to prove an understanding of my perception of reflection and how reflective practice impacts on the clinical environment and the learning process. The essay is based on my practice and training in the cardiac ward during my Foundation degree in Health and Social Care. I have selected 5 extracts from my Reflective Journal concerning a patient experiencing shortness of breath which led to a cardiac arrest. In order to be able to use this situation for my

Essay ON PAcemaker A pacemaker (or artificial pacemaker‚ is a medical device that uses electrical impulses‚ delivered by electrodes contacting the heart muscles‚ to regulate the beating of the heart. The primary purpose of a pacemaker is to maintain an adequateheart rate‚ either because the heart’s native pacemaker is not fast enough‚ or there is a block in the heart’s electrical conduction system. Modern pacemakers are externally programmable and allow the cardiologist to select the optimum pacing
