Amacrine Cells are interneurons in the retina. These cells are responsible for 70% of the input to retinal ganglion cells. They are located inner nuclear and Ganglion cell layers of the retina. Amarcrine cells are apolar or nonpolar neurons i.e. they do not have axons. Cell process is either absent or if present is not differentiated in axon and dendrons. Nerve impulses radiate in all directions

The nurse is assessing a woman in labor. He knows that fetal bradycardia occurs when the heart rate drops below 110 beats per minute.

Fetal bradycardia is recognized when the fetal heart rate drops below 110 beats per minute for 10 minutes or longer. The normal fetal heart rate is between 120 beats per minute and 160 beats per minute. Fetal tachycardia is a heart rate above 160 beats per minute.

Hemolytic jaundice, also known as prehepatic jaundice, is a type of jaundice arising from hemolysis or excessive destruction of red blood cells when the byproduct bilirubin is not excreted by the hepatic cells quickly enough.

Cinchona officinalis is a tree, a member of Rubiaceae, bark of this plant, produces a drug called quinine, used for control of malaria.

During a rapid assessment, the nurse’s first priority is to check the patient’s vital functions by assessing his airway, breathing, and circulation. To check a patient’s circulation, the nurse must assess his heart and vascular network function. This is done by checking his skin color, temperature, mental status and, most importantly, his pulse. The nurse should use the carotid artery to check a patient’s circulation.

Prothrombin time is a coagulation test that indicates the efficiency of an extrinsic pathway. Prothrombin time requires the presence of factors I, II, V, VII, and X. It measures the extrinsic pathway of coagulation and can be used in conjunction with the activated partial thromboplastin time (aPTT) which measures the intrinsic pathway.

The prothrombin time, sometimes referred to as PT or pro time, test is a test to evaluate blood clotting. Prothrombin is a protein produced by your liver. It is one of many factors in your blood that help it to clot appropriately.

Inserting thin needles into specific points on the skin to relieve pain is called acupuncture.

“I just can’t seem to get down to the weight I want to be. I’m so fat compared to other girls” comment indicates that the client may be suffering from anorexia nervosa.

The volume of air inspired or expired during normal breathing is Tidal volume.

Tidal volume is the amount of air that normally goes in and out of the lungs during breathing (500 ml). A healthy man inspires or expires approximately 6000 to 8000 mL of air per minute.

It is the only gland in the human body Pancreas has both endocrine and exocrine properties.

• A gland is a group of cells or a “secreting organ” that excretes a chemical substance. This substance can take the form of hormones, sweat, saliva, mucus, or acids.
• Pancreas is a heterocrine gland because the endocrine part secretes insulin and glucagon and the exocrine part secretes an acidic pancreatic juice containing enzymes.

The population of algae in soil is generally smaller than that of either bacteria or fungi.

Algae are scarcely populated in soil and their presence in soil and its activities is smaller when compared to that of either bacteria or fungi. Algal population in soil usually ranges from 100 to 10,000 numbers per gram of soil.

p53 is known as Guardian of genome.

By stopping cells with mutated or damaged DNA from dividing, p53 helps prevent the development of tumors. Because p53 is essential for regulating DNA repair and cell division, it has been nicknamed the "guardian of the genome."

When the velocity of enzyme activity is plotted against substrate concentration, the curve obtained is hyperbolic.

When the concentration of substrate is less, the rate of the enzyme reaction is dependent on the concentration of enzynme-substrate complex. If we draw a plot of velocity of enzyme activity against substrate concentration, a hyperbolic curve will be obtained.

Definition of mental retardation deficits in adaptive behavior with intellectual impairment.

Deficits in adaptive behaviour refer to how well a person meets cultural and age-related standards of independence and social responsibility.

A check for scoliosis, a lateral deviation of the spine, is an important part of the routine adolescent exam. It is assessed by having the teen bend at the waist with arms dangling, while observing for lateral curvature and uneven rib level. Scoliosis is more common in female adolescents.

Aging-related physiological changes account for the increased frequency of adverse drug reactions in geriatric patients. ADEs(adverse drug effect) are estimated to be indicated in 5 to 28 of acute geriatric medical admissions. Preventable ADEs(adverse drug effect) are among one of the serious consequences of inappropriate medication use in older adults.

Cyanobacteria, the oxygenic photosynthetic bacteria, are known to grow on the surfaces of freshly exposed rocks where the accumulation of their cells results in the simultaneous deposition of organic matter.

The nurse should return shortly to the patient’s room and remain there until the patient takes the medication to verify that it was taken as directed. With the growing reliance on medication therapy as the primary intervention for most illnesses, patients receiving medication interventions are exposed to potential harm as well as benefits. Benefits are effective management of the illness/disease, slowed progression of the disease, and improved patient outcomes with few if any errors. Harm from medications can arise from unintended consequences as well as medication error (wrong medication, wrong time, wrong dose, etc.).

Cleaning from the center outward in a circular motion action by the nurse in charge is essential when cleaning the area around a Jackson-Pratt wound drain.

The nurse always should clean around a wound drain, moving from the center outward in ever-larger circles, because the skin near the drain site is more contaminated than the site itself. A Jackson-Pratt (JP) drain is used to remove fluids that build up in an area of the body after surgery. The Jackson-Pratt drain is a bulb-shaped device connected to a tube. One end of the tube is placed inside the patient during surgery. The other end comes out through a small cut in the skin. The bulb is connected to this end. The patient may have a stitch to hold the tube in place.

Just as, JUG = 38 = 10 + 21 + 7  and, WATER = 67 = 23 + 1 + 20 + 5 + 18 
Similarly, GLASS = 7 + 12 + 1 + 19 + 19 = 58 

An electron has 1.602 × 10^-19 C of negative charge.

IgE, the least common serum immunoglobulin (Ig) binds very tightly to receptors on basophils and mast cells and is involved in allergic reactions. Binding of the allergen to the IgE on the cells results in the release of various pharmacological mediators that result in allergic symptoms.

Dapsone is useful for the treatment of all except Lymphoma.

Dapsone is used to treat leprosy (Hansen's disease) and to help control dermatitis herpetiformis, a skin problem. When it is used to treat leprosy, dapsone may be given with one or more other medicines. Lymphoma treatment may involve chemotherapy, medication, radiation therapy and rarely stem-cell transplant but daspone is not use at all. Dapsone may also be used for other conditions as determined by the doctor.

Hence, the correct option is (B).

The key enzyme in the cyclooxygenase pathway is the enzyme cyclooxygenase (COX). There are two forms of cyclooxygenase, COX1 (the predominant form) and COX2. NSAIDs inhibit prostaglandin and thromboxane synthesis, they are potent inhibitors of cyclooxygenase and eliminate all prostaglandins and thromboxanes in every cell they reach.

Partial Convertibility of Rupee was introduced in March 1992. When partial convertibility obtains the exchange rate is a weighted average.

The Brihadeshwara Temple at Tanjore was built by Rajaraja I in 1009 CE for worshipping Lord Shiva. Built between 1003 and 1010 CE the temple is a part of the UNESCO World Heritage Site known as the "Great Living Chola Temples".

Fluid intake should be approximately equal to the urine output.

Normally, fluid intake is approximately equal to the urine output. Any other relationship signals an abnormality. One general principle for all patient scenarios is to replace whatever fluid is being lost as accurately as possible. The strategy of managing a patient’s fluid differs depending on each patient’s clinical condition. If they can drink adequate fluid volumes by mouth, this should be the first choice. Some patients can tolerate other enteral options, such as feeding tubes. IV plus oral orders are effective for those unable to meet their total daily fluid requirements enterally.
