Answer:

The correct answer to the question: The pineal body secretes which hormone that maintains the body´s internal clock, the 24-hour wake-sleep cycle, and regulates the onset and duration of sleep?, would be, C: Melatonin.

Explanation:

The process of sleep and wakefulness, also called the circadian cycle, its a pretty complex system that is controlled by several parts of the brain, but most importantly, structures of the diencephalon (vital is the hypothalamus), the pineal gland, and the stem of the brain. All these structures, and some others, respond to changes both in light perception by the eyes and other senses, heat, and homeostatic balances. These factor play a vital role in telling the human body that it is time for sleep, or to awaken. The pineal gland, as part of this melody, is essential, as it secretes the hormone, melatonin, in response to light changes. Melatonin will balance out the process of sleep, when it is secreted in high quantities by the pineal gland, and wakefulness, when it is no longer secreted in response to the presence of light. This is what is called the circadian cycle.

Sound is more effectively transmitted into a stethoscope by direct contact than through the air, and it is further intensified b
zhenek [66]

Answer: Δβ = 28.5278 dB

Explanation:

from the question we are given that;

the sound gathering area Ga = 15.0 cm²

total area Ae = 0.800 cm²

efficiency ε = 38 %

therefore we have that the effective gathering area of the stethoscope is;

As = ε Ga

As = 38 % × 15 = 5.7 cm²

But I ∝ 1/A

where Ie/Is = As/Ae

Ie/Is = 5.7/0.800 = 7.125

given that we are to assume that  sound is transmitted into a stethoscope 100 times, this gives

I'e/I's = Ie/Is × 100 = 7.125 × 100 = 712.5

Δβ = βe - βs = (10dB) log (I'e/Io) - (10dB) log (I's/Io)

Δβ = (10dB) log (I'e/I's)

Δβ = (10dB) log (712.5) = 28.5278

Δβ = 28.5278 dB

11Alexandr11 [23.1K]

Answer:

Elevate legs while sitting.The nurse should encourage the client to elevate her legs while sitting; this will prevent pooling and engorgement of veins in the lower extremities. Aerobic exercises do not help in preventing varicose veins. Folic acid intake is recommended in the first trimester to prevent congenital abnormalities. Increasing the intake of calcium helps in strengthening bones.

ira [324]

A client with chronic renal failure (CRF) is receiving a hemodialysis treatment. after hemodialysis, the nurse knows that the client is most likely to experience weight loss.

<h3>What is meant by CRF?</h3>

Chronic renal failure is a condition in which the kidneys' ability to filter waste and fluid from the blood decreases. It is chronic, which means that the condition develops over time and is irreversible. Chronic kidney disease is another name for this condition (CKD).

Because CRF results in renal function loss, the patient retains fluid. This fluid is removed during hemodialysis, resulting in weight loss. Hematuria is unlikely to occur after hemodialysis because CRF patients produce little or no urine.

Hemodialysis does not increase urine output because it does not address the loss of kidney function, which significantly reduces urine output in this disorder. Hemodialysis lowers rather than raises blood pressure by removing fluids.

Therefore, the correct answer is option B. weight loss.

The complete question is:

A client with chronic renal failure (CRF) is receiving hemodialysis treatment. After hemodialysis, the nurse knows that the client is most likely to experience:

A. hematuria.

B. weight loss.

C. increased urine output.

D. increased blood pressure.
