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.

Thermophilic anaerobe spoilage of low and medium acid canned products such as corn, peas, spinach are caused by Clostridium thermosaccharolyticum. It can swells and may burst. Clostridium thermosaccharolyticum is a bacterium belonging to the Firmicutes. It is an anaerobic, motile, gram-positive bacterium.

The malarial Plasmodium parasite has two host life cycle, first in a vector (mosquito) and other in a human host. The cycle begins when a female mosquito bites a human. The parasite is transferred through the mosquito saliva to the human host. After infecting, the parasites in sporozoites form travel through the bloodstream to the liver and invade liver cells. Later, the sporozoites grow, divide and produce thousands of merozoites per liver cell. The merozoites leaves the liver and reenter the blood stream where they invade red blood cells to feed on hemoglobin. The merozoites multiply inside the red blood cells. The red blood cells eventually break open and merozoites affect more red blood cells. In severe cases, the infected blood travels to the kideny and affect kidneys and may result in renal failure.

Accept responsibility for own behaviors would be appropriate for a child diagnosed with the oppositional defiant disorder.

The inner walls of small intestine have thousands of finger-like outgrowths. These are called Villi.

The small little projections on the inner surface of the small intestine which help in absorbing the digested food are called villi. They are finger-like projection inside the small intestine to increase their surface area to absorb essential nutrients from the food. They have thin walls and mostly covered with a thin channel of blood capillaries so, the nutrients can be absorbed by blood and easily transport.

Disappearance of cervix during labor is called Effacement.

• Effacement refers to the thinning of the cervix during labor.
• During labor, the cervix shortens, dilates, and almost disappears toward the uterus in preparation for childbirth.

A fracture in which there is no break in the skin is called closed fracture.

• Closed fractures: If the injury doesn't break open the skin, it's called a closed fracture.
• A fracture is a break or disruption in the continuity of the bone.

Acetylcysteine (Mucomyst) drugs should Nurse Mary prepare to administer to a client with a toxic acetaminophen (Tylenol) level.

Palpable pyloric tumour and projectile vomiting is found in Pyloric stenosis.

• Pyloric stenosis is an uncommon condition in infants that blocks food from entering the small intestine.
• Normally, a muscular valve (pylorus) between the stomach and small intestine holds food in the stomach until it is ready for the next stage in the digestive process. In pyloric stenosis, the pylorus muscles thicken and become abnormally large, blocking food from reaching the small intestine.
• Pyloric stenosis can lead to forceful vomiting, dehydration and weight loss. Babies with pyloric stenosis may seem to be hungry all the time.

Functional Residual Capacity refers to the amount of air remaining in the lungs after normal expiration.

Tachycardia, a heart rate of 120 to 140 beats/minute, is a common sign of alcohol withdrawal. Blood pressure may be labile throughout withdrawal, fluctuating at different stages. Hypertension typically occurs in early withdrawal. Hypotension, although rare during the early withdrawal stages, may occur in later stages. Hypotension is associated with cardiovascular collapse and most commonly occurs in clients who don’t receive treatment. The nurse should monitor the client’s vital signs carefully throughout the entire alcohol withdrawal process.

The S1 sound—the “lub” sound—is loudest at the apex of the heart. It sounds longer, lower, and louder there than the S2 sounds. The S2—the “dub” sound—is loudest at the base. It sounds shorter, sharper, higher, and louder there than S1. Heart sounds are created from blood flowing through the heart chambers as the cardiac valves open and close during the cardiac cycle. Vibrations of these structures from the blood flow create audible sounds — the more turbulent the blood flow, the more vibrations that get created.

Numerical taxonomy is a biological systematics classification system that deals with the numerical grouping of taxonomic units based on their character states.

• Its goal is to establish a taxonomy utilizing numerical algorithms such as cluster analysis rather than subjective property evaluation.
• Robert R. Sokal and Peter H. A. Sneath first proposed the idea in 1963, and the same authors later expanded on it.
• They divided the field into phenetics, which classifies organisms based on overall similarity patterns, and cladistics, which classifies organisms based on the branching patterns of the taxa's estimated evolutionary history.
• The relationships between organisms are mathematically established, usually with the help of a computer, and their characteristics are given equal weight.
• Thus, the numerical taxonomy of plants is based on all observable characteristics.

St. John’s wort has been found to have serotonin-elevating properties, similar to prescription antidepressants. St. John’s Wort (Hypericum perforatum) is commonly used to treat mild-to-moderate depression. Several bioactive compounds have been identified in St. John’s Wort that work synergistically to provide its antidepressant and anti-inflammatory attributes. St. John’s Wort was more efficacious than standard antidepressant therapy in patients with mild-to-moderate depression.

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.

Homeopathy was invented by Samuel Hahnemann. Homeopathy is a system of alternative medicine that originated in 1796.

Homeopathy achieved its greatest popularity in the 19th century. It was introduced in the United States in 1825 with the first homeopathic school opening in 1835.

The growth rate of Financial services has very low employment elasticity. The term "employment elasticity" refers to the responsiveness of employment to changes in economic growth.

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".

The nurse should check Urine output before administering IV prescription.

When it comes to hypotonic dehydration, electrolyte loss exceeds water loss. The priority assessment for the nurse is to check the urinary output before the administration. Potassium chloride is contraindicated for patients with oliguria or anuria. The body becomes dehydrated when it loses more fluids than it consumes. When the body doesn’t have enough fluids, it can’t process potassium properly, and potassium builds up in the blood, which can lead to hyperkalemia.

To calculate the rate of urine output, divide the volume of urine produced by the number of hours that have elapsed since the bag/chamber was last emptied

A nurse prepares to administer an intramuscular injection to a 6-month-old infant. The nurse selects Vastus lateralis to administer the medication.

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.
