Answer:
ECG paper is a grid where time is measured along the horizontal axis.
Each small square is 1 mm in length and represents 0.04 seconds.
Each larger square is 5 mm in length and represents 0.2 seconds.
Voltage is measured along the vertical axis.
10 mm is equal to 1mV in voltage.
The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form
Heart rate can be easily calculated from the ECG strip:
When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.
For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).
The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.
For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).

Martha Wembly has a history of diabetes mellitus, type 2. How is this different from diabetes mellitus, type 1
Answers
Answer and explanation:
Diabetes Mellitus is a condition characterized by high blood sugar levels (hyperglycemia), if not properly controlled this disease can severely damage many organs and cause death.
There are different types of Diabetes Mellitus, Type 1, Type 2, and Gestational (this type of diabetes, in particular, is unique to pregnant women).
In a healthy body, when blood sugar levels are high (for example, right after we eat), Insulin would be released from the pancreatic beta-cells to induce the entering of glucose (also called sugar) into different tissues such as skeletal muscle and fat, where it will be used to produce energy and store the excess for when the body needs it.
Patients that suffer from Diabetes Mellitus cannot get the glucose they ingest into the mentioned tissues, and for that reason, the blood sugar levels stay high and can produce several life-threatening consequences. This incapacity can have different roots and is the reason behind the classification of this condition.
Type 1 Diabetes is the most uncommon of the two and it appears for the first time during childhood or teenage years. Patients with type 1 Diabetes CANNOT produce Insulin, because their pancreatic beta-cells are deficient. For this reason, these individuals have to be administered exogenous Insulin for the rest of their lives.
Type 2 Diabetes is, by far, the most common type of Diabetes. Unlike type 1 diabetics, these patients can produce glucose, but the combination between genetic predisposal and unhealthy habits such as poor diets or sedentarism can lead to a condition called Insulin resistance, in which the tissues cannot accept the glucose even if there's Insulin around. This type of Diabetes usually starts manifesting during adulthood (especially in patients that are older than 40 years old) and is treated with specific medication and a change in their habits.

Calculate the dose of acetaminophen for a 3-year-old child with the body surface area of 0.30 m2. The adult dose of the drug is 500 mg. Record your answer using a whole number. _____mg
Answers
Answer:
87 mg
Explanation:
To find the dose of acetaminophen for a 3-year-old child with the body surface area of 0.30 m², we use the formula given below
Child dose = child surface area/1.73 × adult dose
Given that the child surface area = 0.30 m² and the adult dose = 500 mg,
Child dose = child surface area/1.73 × adult dose
Substituting the values of the variables into the equation, we have
Child dose = child surface area/1.73 × adult dose
Child dose = 0.30 m²/1.73 × 500 mg
Child dose = 0.1734 × 500 mg
Child dose = 86.71 mg
Child dose = 87 mg to the nearest whole number

The child is experiencing infective endocardits.
Treatment with aqueous penicillin or ceftriaxone is more effective foe most infections caused by streptococci. The combination of penicillin or ampicillin with gentamicin is appropriate for endocarditis caused by enterococci that are not highly resistant to penicillin intial empiric therapy in patients with suspected endocrditis should include plus in an aminoglycoside
The valve replacement is considered in selected patients with infectious endocarditis
The common congental defects that cause hearts murmurs include holes in the heart or cardiac shunts which is known as septal defects.
The disease that should be considered is infective endocarditis whose treatment can be based on antibiotics.
Infective endocarditis is a type of infection in the internal heart tissue called the endocardium.This disease (infective endocarditis) may be caused by different harmful microorganisms (.e.g, bacteria, fungi, etc), which in this case could have entered into the body through the skinned knee.Infective endocarditis can be treated by using proper antibiotics to kill harmful microorganisms.In conclusion, the disease that should be considered is infective endocarditis whose treatment can be based on antibiotics.

A weight reducing diet required the daily intake of ‘liquid protein’[soup of hydrolyzed gelatin], water and an assortments of vitamins. All other food and drink were to be avoided. People on this diet typically lost 10 to 14kg in the first week. A number of persons on this diet died. What are some of the dangers inherent in the diet and how can they lead to death?
Answers
Answer: See explanation
Explanation:
From the information given, it should be noted that Gelatin has a nutritional distribution of amino acids that's unbalanced.
It should be noted that in a scenario whereby large amounts of gelatin are ingested into the body such that there is catabolizing of the excess amino acids, there will be an excess of the urwa cycle capacity which then brings about ammonia toxicity.
Furthermore, the dehydration which can be caused due to the excretion of large amount of urea can also lead to death.
