Answer:

The correct answer will be option C- increase the surface area.

Explanation:

At the neuromuscular junctions, the axons of the motor-neurons become bulbous at terminals. These bulbous enlargements are known as the synaptic knobs. The synaptic knob is the bulbous enlargements of the axon present at the terminals. These knobs increase the volume of the axon terminals embedded with the ligand-gated channels and accumulation of neurotransmitters in vesicles.

The motor end plate is the region of the muscle fiber which is responsible for initiating the action potential in a muscle. The motor end plate becomes ruffled or shows small folds or clefts to increase the increased surface area for the neurotransmitter to act.

Thus, option C is the correct answer.

Pathophysiological problems refers to the study of the adverse changes that occur in the normal physical, mechanical and biochemical functioning of the body. These changes are caused either due to a disease or an abnormal syndrome.

The given situation is an example of the pathophysiological problem. This is due to abnormal changes in the physical, mechanical and biochemical functioning of the body. The physical changes includes the shortness of breath, swollen ankles , three gallops and not being able to sleep in flat position. The increased jugular venous pressure, crackles in the lung, are the example of the mechanical changes in the pathophysiological problem.

A patient is diagnosed with urinary tract obstruction. while planning care, the nurse realizes that the patient is expected to have hydronephrosis and a decreased glomerular filtration rate caused by <u>Renal pelvis and calyces that are close to a blockage enlarge</u>.

Because of a blockage in the urine's outflow distal to the renal pelvis, hydronephrosis is described as the dilatation and distension of one or both kidneys' renal collecting systems (i.e., ureter, urinary bladder, and urethra). Hydroureter refers to ureteral dilation brought on by blockage of urine outflow.

Intrinsic and extrinsic compression are two major categories for the causes of urinary tract obstruction. Renal stones, cancer, ureteropelvic junction stenosis, ureteral strictures from earlier inflammation, renal cysts, posterior urethral valves, benign prostatic hyperplasia, neurogenic bladder, and others are causes of intrinsic obstruction.

Extrinsic compression can be brought on by conditions such as pregnancy, peripelvic cysts, retrocaval ureters, cancer, trauma, retroperitoneal fibrosis, and prostate abscess, among others.
