hormone that is available to interact with and affect the target cells. Also‚ the target cells have receptors that latch only onto specific hormones‚ and each hormone has its own receptor‚ so that each hormone will communicate only with specific target cells that possess receptors for that hormone. When the hormone reaches its target cell‚ it locks onto the cell’s specific receptors and these hormone-receptor combinations transmit chemical instructions to the inner workings of the cell. When hormone levels

Side effects such as renal impairment and hypotension can arise‚ as well as a dry cough (NICE‚ 2014). If the patient is being affected by this‚ angiotensin II receptor blockers (ARBs) can be prescribed instead. ARBs‚ such as candesartan and losartan‚ have a similar action to ACE inhibitors‚ but they do not usually cause the persistent cough (NHS‚ 2016). They may also cause hypotension and hyperkalaemia.

Heart failure (HF) is a progressive disease which affects more than five million Americans (Yancy et al.‚ 2013). HF negatively impacts quality of life and it is associated with frequent hospitalizations and high mortality. Evidence-based practice guidelines aid health care professionals with treatment management and provide pathways to optimize individual patient care. The main goal of treatment is to slow the progression of the disease and control its symptoms. These pathways address all stages

1) Introduction Shock is a syndrome‚ in which oxygen supply to various tissues and organs of the body are interrupted.1 It represents the final common pathway‚ of a variety of potentially lethal diseases and conditions.2‚3 It is a medical emergency‚ involving acute tissue hypoperfusion and cellular destruction‚ and will ultimately lead to organ failure and death‚ if left untreated.2‚3 Despite a huge amount of research into understanding the syndrome‚ it remains a very common clinical condition

Excretory System Review Main Concepts: Describe the major gross anatomical structures of the excretory system. Kidneys: receive about 25% of the cardiac output; produce urine (a fluid containing water‚ ions‚ and small soluble compounds) Ureters: receive urine from the kidneys and conduct it to the urinary bladder. Urine movement involves a combo of gravity and the peristaltic contractions of smooth muscle in the walls of the ureters Urinary Bladder: receives and stores urine prior to elimination

As the evolution of animals has evolved‚ the organization and function of internal body structures has increased in complexity. As a result‚ the process of homeostasis has taken the role of maintaining the body’s ability to properly function. Homeostasis is defined as a process in the body that attempts to stabilize and maintain a constant condition in a biological system by means of automatic mechanisms that work against influences leaning towards disequilibrium. This action primarily aims to preserve

Situation: Two patients in their 70s present to the office at different times today‚ each with documented heart failure: one diastolic and the other systolic‚ and both are hypertensive. First‚ discuss the difference between systolic and diastolic heart failure‚ providing appropriate pathophysiology. ACEI/ARBs are the only medications prescribed for CHF that have been found to prolong life and improve the quality of that life. EXPLAIN the mechanism of action of ACEI/ARBs and how they affect morbidity

Describe the preoperative and postoperative care of a client having PTCA/cardiac cath. What complications can occur post cardiac cath? The goal of PCI (percutaneous Transluminal intervention) is to open the blockage in the coronary artery. By opening the area that is blocked‚ it will help to reperfuse the myocardium. The faster this is done will help
