This assignment will focus on an account of patient care that I have provided to a patient who was unable to excrete urine during a long day shift in a secondary care setting. It will discuss regarding my contribution to a change in care while assessing the patient. The assessment will be evaluated to help analyse and synthesise information, make evidence- based decision and implement these decisions into clinical environment appropriately which is also known as clinical decision making according to Pritchard (2006). I will be using evidence based research and appropriate pathophysiology to understand why the patient had to be catheterized. Consent has been gained and a pseudonym is given to protect the patients’ identity as people have the right to confidentiality according to Nursing and Midwifery Council (NMC, 2008a). Therefore she will be addressed as Tania.…
C. The function of ADH is to conserve body water by reducing the loss of water in urine…
3. Burn patients have damaged skin cells that are unable to prevent water loss. The kidneys help retain water by using the sodium-potassium pump. It pumps more sodium into the cells so that water can follow the movement of sodium and can be reabsorbed. Sodium ions are exchanged with potassium being pumped out of the cells into the renal tubules, where it's secreted in urine. Therefore, potassium levels in urine are high.…
The physiological overview involves the kidneys processing blood by eliminating any excess mineral salts, urea and water as this provides homeostasis and it enables the body to work effectively. The nephron (which is part of the kidneys) for example, is in charge of the reabsorption of amino acids, glucose, some chloride and sodium. It is composed of the Bowman’s capsule which is connected to a coiled tubule, which then moves into a hairpin loop called the loop of Henle. There is also a straight collecting duct and second loop that clears out at the end of the pyramid. Both the collecting duct and loop of Henle are located in the medulla.…
ADH (Vasopressin) – ADH has an antidiuretic action that prevents the production of dilute urine.…
Aldosterone falls in the class of hormone called mineralocorticoids, produces by the adrenal glands and is found near the kidneys. It sustains blood pressure, water and salt balance within the body. This procedure is assisting the kidneys to preserve sodium and excrete potassium in order to maintain a balance. If Aldosterone production falls, there isn’t enough regulation of salt and water balance (as aldosterone is being lost through urination) triggering blood pressure and blood volume to decline as a result of the kidneys not functioning properly. If body is in need of salt, water is not retained and adrenals release more Aldosterone and salt is reabsorbed from the tubule.…
|Antidiuretic hormone (ADH) |The hormone made in the hypothalamus and released from the pituitary gland that acts on the collecting…
Hyponatremia is even more susceptible to happen to athletes. When we are under physical stress, to which athletes experience during games, our hypothalamus produces antidiuretic hormone secreted into our blood stream by our pituitary gland sending messages to our kidneys to hold the secretion of water. The conserved water plus the excessive amount we drink during that time will lead to exercise-associated hyponatremia or also known as EAH (Joseph Verbalis, Georgetown University Medical Center Chaiman of Medicine).…
d. Describe the collecting duct role relative to urine concentration. Depending on the body fluid osmolarity, the collecting duct reabsorbs water & forms concentrated urine or if water is allowed to pass, dilute urine is formed.…

The reasoning behind this is that when traveling down the collecting duct the concentration of salt is almost similar both on the inside and in the interstitial fluid. The collecting duct is permeable to water and not salt, so water is drawn out via osmosis, which is determined by Antidiuretic Hormone secretion (3). Whether or not water needs to be conserved determines the amount of ADH that is released. If the hormone ADH is high, then the collecting duct becomes more permeable to water so more water is drawn out which means that less urine volume and it will be more concentrated. If ADH is low then less water is removed and the urine volume is large and more diluted. For the salt group, eating potato chips and drinking the salt solution increased the amount of sodium in the blood, leading to more water reabsorption and water retention. The increased Na in the blood will be filtered into the nephron. The increase makes the sodium transporters not able to reabsorb all of the sodium. Therefore, excess sodium and water will remain in the lumen (3). The excess sodium will be excreted into the urine and eliminated from the body. A substance can remain in the blood depending on the amount filtered into the nephron and the amount reabsorbed or secreted by…
The kidneys remove extra body fluids in the bloodstream, this waste is stored in the bladder. If the fluid regulation system is working right the kidneys will make less urine to save your body's fluids so you don't become dehydrated.…
Keeping patients hydrated by giving them enough clean water and monitoring their fluid intake to prevent dehydration effects, such as dizziness and dry mouth, is seen in the RCN’s enhanced nutritional care, which was formed using Florence Nightingale’s theory on keeping a clean environment for the patients’ recovery. In Nightingale’s environmental theory, making sure that the water is clean and pure can prevent patients from getting sicker when around patients who have other diseases instead of using polluted water from poor drainage to be used for patients’ healing (Nightingale, 1850). Today, there are nearly 38% of hospitals and health-care facilities around the world are unable to use safe, clean water; and the Royal College of Nursing recognized this that they ensure patients in acute care receive clean, fresh water to encourage hydration.…
The walls of duct in the kidney respond to ADH and the cells in the walls have membrane-bound receptors for ADH, to which the ADH binds to these receptors and causes a chain of enzyme-controlled reactions in the cell. The completion of these reactions is inserting vesicles containing water-permeable channels (aquaporin’s) into the cell surface membrane, thus making walls more permeable to water. When ADH is increased in the blood flow, more water-permeable channels are inserted, allowing more water to be reabsorbed by osmosis into the blood stream. When this happens, less urine, of a much lowered water potential, passes out of the body. This suggests that due to the cell walls being more permeable to water and also osmosis reabsorbing the water, this in turn lead to Leah’s water intoxication, as it was stored in the body opposed to leaving it correctly. Consequently if there is less ADH in the blood, the cell surface membrane is then able to fold inwards creating new vesicles to remove water-permeable channels from the membrane. When this occurs, it makes the walls less permeable meaning less water is then reabsorbed, by osmosis, into the blood. This again shows due to the consumption of ecstasy, Leah had increased ADH, fundamentally leading to water…
