Answer:
(D). cesarean section
Explanation:
Oxytocin is a peptide hormone, synthesized by hypothalamus and secreted by posterior pituitary. Oxytocin plays role in sexual reproduction, lactation, and induce contractions during child birth.
Oxytocin is naturally produced at the time of child birth, but natural oxytocin has a short half-life. Hence, oxytocin infusion is done during child birth or cesarean section as it maintains contraction of uterine wall during the surgery.
Thus, the correct answer is option (D).

The liver plays a role in the metabolism of lipds. It packages lipids for storage or transport that are bound to small proteins called ____________.
Answer:
Lipoproteins (LDL, HDL, VLDL, IDL, Chylomicrons
Explanation:
The lipids transport is difficult because of their hydrophobic attribute, so they cant move easily through the plasma. After being transported those lippoproteins get in the cells thanks to the receptors in cell membrane (B:E, E and scavangers receptors). Only if they are bounded to the proteins they can go out and in through the plasma and different cells in the organism.

Inhibin is thought to be released in response to developing sperm and is thought to:
a. inhibit FSH secretion
b. inhibit estrogen secretin
c. inhibit PRL secretion
d. inhibit progesterone secretion
e. inhibit LH secretion
Answer:
A. Inhibit FSH secretion.
Explanation:
Inhibin is a hormone secreted by the granulosa cells in the ovaries of women and the Sertolli cells in men. The main function of inhibin, as they name says, is to inhibit the secretion of FSH by the anterior pituitary gland. Inhibin is also produced by the Sertolli cells in the testes of men, and it is released in the blood when the sperm count is too high. FSH causes the Sertoli cells of the testes to begin the process of spermatogenesis in the testes. Therefore, releasing inhibin would cause a negative feedback and stop the production of sperm.
A nurse is administering medications to a client and mistakenly gives hydroxyzine instead of hydralazine. The nurse should monitor the client for which of the following adverse effects?
a. Edema
b. Diplopia
c. Fever
d. Sedation
Answer:
The answer is D sedation.
Explanation:
hydroxyzine is a medicine that is used as an antihestaminic agent and can cause sedation, because it crosses the blood-brain barrier. In fact it is a medicine that can be used in anxiety and depression.
Hydroxyzine may cause sedation when administered accidentally instead of hydralazine, hence the patient should be closely monitored for this effect.
Explanation:If a nurse accidentally administers hydroxyzine instead of hydralazine, the client should be monitored for signs of sedation. Hydroxyzine is an antihistamine medication that is commonly used to treat allergy symptoms. However, one potential side effect of this medication is drowsiness or sedation, as it tends to suppress the central nervous system. Hydralazine, on the other hand, is a medication used to treat high blood pressure and its mistaking could lead to adverse effects that are related to blood pressure regulation.

Which of the following does NOT involve the hypothalamic-pituitary axis of hormone function regulation?
A. prolactin
B. somatotropin
C. cortisol
D. oxytocin
E. T3
Answer:
(D). oxytocin.
Explanation:
The hypothalamic-pituitary axis can be defined a pathway that plays a central role in regulation of various endocrine glands. Hormones released from hypothalamus stimulates pituitary gland, which in turns secrete pituitary hormones to regulate release of hormones from other endocrine glands.
Regulation of growth hormone (somatotropin), cortisol (adrenal hormone), prolactin, and T3 (thyroid hormone) is done by hypothalamic-pituitary axis.
Oxytocin is a peptide hormone, which is synthesized by hypothalamus and secreted by posterior pituitary gland. However, level of oxytocin is regulated by positive feedback in loop, in which hormone itself regulates its release and does not involves regulation by hypothalamic-pituitary axis.
Thus, the correct answer is option (D).
Final answer:
D. Oxytocin does not involve the hypothalamic-pituitary axis of hormone function regulation because it is produced in the hypothalamus and directly secreted by the posterior pituitary, unlike other hormones that are regulated through the axis.
Explanation:
The student asked which of the following does NOT involve the hypothalamic-pituitary axis of hormone function regulation. The options were prolactin, somatotropin, cortisol, oxytocin, and T3. The hypothalamic-pituitary axis is a central part of the endocrine system that regulates a wide array of body functions. Prolactin, somatotropin (growth hormone), cortisol via ACTH, and T3 via thyroid-stimulating hormone are all hormones whose regulation involves the hypothalamic-pituitary axis.
However, D. oxytocin is not regulated by this axis; instead, it is produced in the hypothalamus and stored and secreted by the posterior pituitary gland without the intermediary hormone regulation that characterizes the anterior pituitary hormones. Therefore, oxytocin is the correct answer because it does not involve the hypothalamic-pituitary axis in its regulation.
What is the percentage of amount of water found in the body?

Water reabsorption, the absorption of vitamins produced by normal bacteria, and packing and compacting waste products for elimination takes place in _____________.
Answer:
Large intestine is responsible for water reabsorption and vitamins absorption produced by the bacteria and compacting the waste materials to be eliminated.
Explanation:
The large intestine, also called colon, is an organ of the digestive system. The function of the colon is the extraction or reabsorption of water and absorption of minerals present in the food. The colon compacts and stores the remaining indigestible waste material in the rectum to be removed by defecation.
The large intestine is the site for flora-aided fermentation of the waste material and leads to the production of vitamins such as vitamin K, thiamine and riboflavin. These vitamins are also absorbed by the colon.
What major artery feeds into the kidneys?
Answer:
Renal Artery
Explanation:
It arises off the left interior side of the abdominal aorta.
Final answer:
The major artery that feeds into the kidneys is the renal artery, which branches from the aorta and supplies the kidneys with blood through a network of smaller arteries and arterioles.
Explanation:
The major artery that feeds into the kidneys is the renal artery. The renal arteries branch directly from the aorta, the largest artery in the body, entering the kidneys to supply them with blood. Each kidney receives around 10% of the total cardiac output, despite being relatively small organs.
Once they enter the kidneys, the renal arteries divide into several segmental arteries, which further branch into interlobar arteries. These give rise to arcuate arteries and then into cortical radiate arteries, which finally branch into numerous afferent arterioles that enter the capillaries supplying the nephrons. The nephrons are the functional units of the kidneys where the filtration of blood occurs.
Why does a patient with partial gastrectomy need to receive intramuscular vitamin B12, in order not to become anemic?
Answer: Due to malabsorption of Vitamin B12
Explanation:
The patients of gasrectomy face several problems which includes anemia as a result of iron or Vitamin B12 malabsorption.
This problem takes place when the intrinsic factor is not produced by the stomach, which helps in the absorption of iron. This is because the proximal part of the stomach is cut.
In this case the iron is not properly absorbed due to this patients with partial gastrectomy face several problems.
To treat gastric acid reflux, one may prescribe a(an) _______ inhibitor.
A. H+ ATPase pump
B. H+/K+ ATPase pump
C. Na+/H+ antiporter
D. Na+/H+/CI- symporter
E. H+/CI- ATPase pump
Answer:
(B). H⁺/K⁺ ATPase.
Explanation:
H⁺/K⁺ ATPase (or hydrogen-potassium pump) is a proton pump, present in parietal cells of stomach. The main function of hydrogen-potassium pump is to acidify the contents of stomach and to activate pepsin (a digestive enzyme).
It helps in gastric acid formation releasing hydrogen ions to the lumen with exchange of potassium ions.
Gastric acid reflux represents a condition, in which stomach acid comes up to the esophagus from stomach. Hence, one way to treat gastric acid reflux is to inhibit H⁺/K⁺ ATPase that would decrease synthesis of gastric acid in stomach.
Thus, the correct answer is option (B).
