The anterior pituitary gland produces corticotropin, a 39-residue hormone that activates the adrenal cortex.

Adrenocorticotropic hormone (corticotropin; ACTH) is a 39 amino acid peptide hormone produced by cells of the anterior pituitary gland and carried by the peripheral circulation to its effector organ, the adrenal cortex, where it stimulates the synthesis and secretion of glucocorticoids.

Restraints can be used for all of the given purposes except prevent a patient from becoming confused or disoriented.

By restricting a patient’s movements, restraints may increase stress and lead to confusion, rather than prevent it. Restraints in a medical setting are devices that limit a patient’s movement. Restraints can help keep a person from getting hurt or doing harm to others, including their caregivers. They are used as a last resort. The other choices are valid reasons for using restraints.

From the Choroid Plexus of the Brain secretes cerebrospinal fluid.

• Cerebrospinal fluid (CSF), clear, colorless liquid that fills and surrounds the brain and the spinal cord and provides a mechanical barrier against shock.
• Formed primarily in the ventricles of the brain, the cerebrospinal fluid supports the brain and provides lubrication between surrounding bones and the brain and spinal cord.
• The Choroid Plexus of the Brain secretes Cerebrospinal Fluid.

Providing motivation is the right way to make learning effective. The ways to make learning effective in psychology are:

• Detailed inquiry
• Self-explanatory
• Practice test
• Distributed exercises
• Interleaved exercises

Neutrophil count of 1,200/mm³ laboratory results indicates that the patient is experiencing a side effect of this medication.

Carbamazepine is used to treat seizures and nerve pain such as trigeminal neuralgia and diabetic neuropathy. It causes a decreased level of platelet count, white blood cells, and neutrophil count. The normal range for neutrophils is 1,500 to 8,000/mm³).

The similarity of bone structure in the forelimbs of many vertebrates is an example of homology.

The homologous organs are those organs which have a common ancestral origin. These are similar in basic structures but perform different functions. The same structures develop along different directions in different organisms due to their adaptations to separate needs because of their different habitats. This type of evolution is called divergent evolution. Homology indicates common ancestry. Hence, homologous organs are the products of divergent evolution.

For example - whales, bats, cheetahs and humans are vertebrates that have similarities in the pattern of arrangement of bones in their forelimbs but these organs perform different functions in these animals.

Assisting the patient with Fowler's position is the nurse’s priority.

The priority action the nurse should take when using the airway, breathing, circulation approach to care delivery is to relieve the patient’s dyspnea. Fowler’s position facilitates maximal long expansion and thus optimizes breathing. With the client in this position, the nurse can better assess and determine the cause of the patient's dyspnea.

Plasma expander is an agent with high molecular weight when administered parenterally remain in the bloodstream & increase circulatory fluid volume by exerting an osmotic pressure.

Plasma expanders are used to restore the circulating volume of a hypovolaemic(A condition in which the liquid portion of the blood (plasma) is too low.) patient. Typically, colloids are used to expand the plasma volume, although combinations of hypertonic crystalloid and colloid have recently been used.

The genes, which remain confined to the differential region of the Y- chromosome, are called holandric genes. These genes are not expressed in females Y-linked holandric genes are transmitted directly from father to son.

Clostridium butyricum is a gas producer organism. Clostridium butyricum causes fermentation of lactose with accumulation of gas. The gas may be a mixture of carbon dioxide and hydrogen or only carbon dioxide in case of yeast fermentation.

Glutamine amidotransferase catalyzes reactions that incorporate nitrogen derived from glutamine.

Glutamine is formed as a result of ligation reaction involving the condensation of glutamate and ammonia. The reaction is catalysed by enzyme glutamine synthetase which is a type of ligase and plays important role in the metabolism of nitrogen. Ligases are a category of enzymes which catalyse the linking together of two compounds. The enzyme utilizes ammonia produced from amino acid degradation and hotoresiration. The reaction involve the ATP dependent condensation of ammonia with glutamate.

For a patient with Crohn's disease, the medical surgical nurse recommends a diet Low in Fiber and High in Protein and Calories.

• Crohn's disease is a type of inflammatory bowel disease (IBD).
• It causes inflammation of your digestive tract, which can lead to abdominal pain, severe diarrhoea, fatigue, weight loss, and malnutrition.
• People with Crohn’s disease are at increased risk for malnutrition and nutrient deficiencies. Poor nutrition makes it more difficult for your body to heal and fight infection.
• So, people with Crohn’s disease should follow a balanced diet and be sure to get enough calories, protein, vitamins, minerals, and fluid.
• A low-fibre with a low-residue diet can help lessen abdominal pain, cramping, and diarrhoea.

"The specific cause of autism is unknown. However, it is known to be associated with problems in the structure of and chemicals in the brain" statement by the nurse would best help alleviate parental guilt.

This statement is factual and does not cast blame on anything the parents did or did not do. The cause is still not known. The onset is variable. It develops in days to weeks, while in other cases, it develops slowly. It is not known whether epilepsy causes it, but children that have an autism spectrum disorder have an increased risk of having epilepsy.

The nurse should do, all of the above priority nursing actions.

The presence of hypertonic contractions indicates the need to initiate emergency measures. The oxytocin infusion must be stopped to reduce uterine stimulation, administering oxygen will promote increased fetal and maternal oxygenation.

Glutamate synthase in bacteria is one of the most sophisticated regulating enzymes known. It catalyzes a reaction in which reduced nitrogen is introduced into cellular metabolism.

Glutamate synthase (GltS) catalyzes the conversion of 2-oxoglutarate into l-glutamate with l-glutamine serving as the nitrogen source for the reaction. The reducing equivalents required for the reaction originate from either a pyridine nucleotide or ferredoxin.

Psychoanalytic theory of personality development was introduced by Sigmund Freud. The Psychoanalytic theory is the personality theory, which is based on the notion that an individual gets motivated more by unseen forces that are controlled by the conscious and the rational thought. It acts as an ethical constraint on behavior and helps an individual to develop his conscience.

Care of the microscope for good result in the case of malarial parasite diagnosis:

Removing dust and grease: During the day, when the microscope is not in use, it should be kept covered with a clean cloth or plastic cover to protect the lenses from settling dust. Overnight, or if the microscope will remain unused for a long time, it should be placed inside its box, with the door tightly closed.

Preventing fungal growth: In warm, humid climates, fungal growths are easily established on lenses and prisms. Fungal growth causes problems and can become so bad that a microscope cannot be used. In such cases, the affected surfaces might have to be cleaned and repolished a job usually done by the manufacturer, which takes time and can be expensive.

Transporting the microscope: When transporting the microscope between laboratories or to the field, it is important to ensure that it is properly secured inside its box. The best way to do this is by screwing the securing device through the hole in the bottom of the box into the base or foot of the microscope. When this is done correctly, the microscope remains rigid in its box on even the roughest road.

In the compensatory shock stage, the patient's blood pressure remains within normal limits. The factors that contribute to maintain adequate cardiac output are increased movement of extremities.

• Compensated shock, the body is experiencing a state of low blood volume but is still able to maintain blood pressure and organ perfusion by increasing the heart rate and constricting the blood vessels.
• The compensatory stage begins as the body’s homeostatic mechanisms attempt to maintain CO, blood pressure, and tissue perfusion.

The intracellular source of digestive enzyme are the Lysosomes. Lysosomes are certain membrane bound cell organelles that contain various essential digestive enzymes that are important to break down the proteins, carbohydrates, lipids and various other complex polymers.

Comparative psychology branch of psychology concerned with the study of animal behavior.

Comparative psychology is the branch of psychology concerned with the study of animal behavior. It utilizes a comparative method to study animal behavior. Comparative psychology refers to the scientific study of the behavior and mental processes of non-human animals, especially as these relate to the phylogenetic history.

Clean the site of injection with soap and water and avoid alcohol of the following should the nurse include in the insulin administration instruction for the parents of a child being discharged on insulin.

Infection risk from insulin injections is negligible (at least in normal environments – some experts feel hospital environments are riskier), and an alcohol swab is a poor way to sanitize skin in the first place. Soap and hot water are actually more effective.

A vascular membrane that covers the marrow cavity of long bones is called the endosteum.

Miscarriage, RH sensitization, and Needle injury all of these are a possible complication of amniocentesis.

Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten hot zinc.

Given,

Two persons working facing each other.

If the first person is facing east direction then second person will be facing west direction.

Therefore, the right hand of the second person will be in the north direction.

The safety of a drug is determined by the degree between therapeutic and toxic doses.

Safety is determined by the degree between therapeutic and toxic doses. The Therapeutic Index ( TI ) is used to compare the therapeutically effective dose to the toxic dose of a pharmaceutical agent. The TI is a statement of the relative safety of a drug. It is the ratio of the dose that produces toxicity to the dose needed to produce the desired therapeutic response.

An addictive effect occurs when two drugs are given together and their effects are equal to the sum of their respective effects. When two drugs are used together, their effects can be additive (the result is what you expect when you add together the effect of each drug taken independently).

Turner’s syndrome is a chromosomal disorder in which a female is born with only one X chromosome (X0).

Henry Turner first described Turner syndrome, which is one of the most common chromosomal abnormalities. Women with this condition tend to be shorter than average and are usually unable to conceive a child (infertile) because of an absence of ovarian function.

Given:

Dividend = 3⁹⁸

Divisor = 5

The given term can also be written as,

= 3⁹⁸

= ( 3²)⁴⁹

= 9⁴⁹

Unit digit of 9⁴⁹ is 9.

On dividing 9 by 5, we get

Remainder = 9-5

= 4

∴ The remainder is 4.

Serous, foamy sputum is typical for Pulmonary edema.

Pulmonary edema is a condition caused by too much fluid in the lungs. This fluid collects in the many air sacs in the lungs, making it difficult to breathe. A cough that produces frothy sputum that may have blood in it is a symptom of Pulmonary edema.
