Answer:

The mechanism of by which kidney forms dilute or concentrated urine is based on the amount of ADH( Antidiuretic hormone) present in the blood. Collecting duct have receptors for the binding of ADH hormone.

Formation of concentrated Urine:                                                        

When the ADH hormone binds to the receptors present on the cells of collecting duct it open the water channels present on it. Once the water channel is opened the duct becomes permeable to water and reabsorption of water takes place in the body making urine concentrated.

Formation of diluted urine:                                                                    

When ADH is not secreted in the blood, the collecting duct remains impermeable to water molecules which results in production of diluted urine. This happens when blood contains sufficient water.

Which set of circumstances will result in a drug undergoing urinary excretion but not urinary reabsorption?
Elza [17]

Drugs are substances resulting in physiological changes. A basic drug; low pH will result in urinary excretion but not urinary reabsorption. Thus, option b is correct.

<h3>What is urinary excretion?</h3>

Urinary excretion is the process of eliminating the waste substance from the body through urine. It is majorly done by the kidneys and their structural unit called nephrons.

The basic drug with low pH will be excreted from the body and will not be reabsorbed as urine has low pH with acidic conditions. The basic drugs undergo changes and get expelled from the body.

Therefore, option b. basic drug with low pH gets excreted.

A client in cardiogenic shock is receiving an infusion of dopamine when it is discovered that extravasation has occurred. What a
Brut [27]

The most appropriate action is to administer Phentolamine.

Extravasation occurs when medication accidentally leaks out of the vein. This means the medicine provided, in this case, dopamine, is in contact with the surrounding tissue. This situation can cause damage to other tissues and due to this, it needs to be immediately solved.

Dopamine extravasation is more common if high doses were given. In these cases, the best option is to administer medicines such as Phentolamine because this stops the action of dopamine, and therefore prevents dopamine from damaging the surrounding tissue.
