Peripheral venous catheter

Nitroglycerin acts directly on vascular smooth muscle to promote vasodilation. Nitroglycerin produces both arterial and venous dilation, which leads increase hemodynamic function, increase CO, and increased tissue perfusion. Venous dilation leads lead to a reduction in return blood flow to the heart and a decrease in preload, while arteriole dilation decreases SVR and afterload. Reduction in preload and afterload leads to reduction…

Introduction The client is MK, a 50 year old female who is status post 3 hours of a percutaneous transluminal coronary angioplasty (PTCA). The PTCA was performed because MK failed a cardiac stress test and was found to have significant coronary disease with a 90% blocked mid-left anterior descending artery and a 90% blocked proximal circumflex artery, which required the placement of two stents. MK is currently employed as a daycare owner, and she is married, but the couple does not have children…

the pulmonary artery to the aorta and out to the body without going through the lung due to the fact that the fetus gets oxygenated from the mother (Ellis, 2016). After birth this artery should close in order to prevent the mixing of arterial and venous…

The heart is a complex organ that we need in order to pump blood to our body. The cardiac cycle and blood pressure (BP) are two things that greatly affect how our body can function. Both are a part of the circulatory system. There are many diseases that can affect the cardiac cycle and the BP. These diseases can affect our circulatory system, lungs, and our heart’s ability to function properly. When the cardiac cycle and BP are affected then the body is in danger of being greatly damaged. The…

Cardiomyopathy is a condition where the heart muscle is abnormal. The main types of cardiomyopathy include dilated, hypertrophic and restrictive cardiomyopathy. Cardiomyopathy makes it harder for your heart to pump and deliver blood to the rest of your body. Cardiomyopathy can lead to heart failure. But to science certain it is not known which is the cause that causes this disease only knows that there is a variety of this disease. Cardiomyopathy can be treated. The type of treatment you 'll…

more information about the murmur, which action will the nurse take next? a. Find the point of maximal impulse. b. Determine the timing of the murmur. USTESTBANK.COM c. Compare the apical and radial pulse rates. d. Palpate the quality of the peripheral pulses. ANS: B Murmurs are caused by turbulent blood flow, such as occurs when blood flows through a damaged valve. Relevant information includes the position in which the murmur is heard best (e.g., sitting and leaning forward), the timing of…

Jones. Mr. Jones appeared to be in distressed. He is now using his accessory muscles to breathe, crackles are heard on auscultation and there is decreased air entry in the left and right bases. Chest X ray revealed consolidation on the left lower lobe and atelectasis in the right lower lobe. After a series of investigation in the emergency department, Mr. Jones was commenced on Normal Saline at 125 mls/hr and he was given oxygen via non rebreather mask at 10L/min. He was then transferred…
