How to calculate the heart rate from the electrocardiogram ?
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).

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
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

Electronic Health Records (EHR) have truly changed everything in US healthcare. But like any major change in healthcare, there are pros and cons, advantages and disadvantages. Please discuss the benefits of EHR implementation, and also discuss the EHR challenges which are being encountered.
Answer and Explanation:
The implementation of EHR can be considered something extremely beneficial for the healthcare system anywhere in the world, due to its numerous benefits such as the centralization of patient information in a single system. This allows any health professional, in any region, to access the patient's health history, test results, medications used by the patient and family history. The EHR also promotes agility in the search for information about the patient and savings in physical space, as the EHR eliminates the need for storing patient papers and documents. Failures in drug prescriptions are also reduced and service and diagnosis are streamlined.
However, some challenges must be overcome for EHR to be efficiently implemented. One of these challenges is the cost, as the implementation of EHR can have a high cost that is passed on to the patient and can become unfeasible. in addition, it is necessary to create a very efficient electronic system, which prevents the existence of data loss, malfunctions and hacker attacks.
Barbara is admitted to Healthwise Hospital for a procedure. This is her first visit/admission to this facility. She is assigned a new health record number for this first visit. If she is admitted or is seen at this hospital again, she will be assigned a new health record number and her old record will be brought forward and filed under the new number. This method of numbering is called _____ numbering.
Answer:
Healthwise Hospital
This method of numbering is called __serial unit___ numbering.
Explanation:
The best way to illustrate this serial unit numbering system is to use the following example. Rafael is registered for the first time in Healthwise Hospital for a medical procedure and he receives the number HH136501. When he comes for a follow-up a month later he is registered again under a new medical record number HH140203 while his previous medical file(s) are brought forward. This continues to happen with each new visit. This system contrasts with serial numbering. Serial numbering involves new numbers being assigned at each visit without reference to previous files. Serial unit numbering also contrasts with unit numbering, where only one number is assigned to a patient in this hospital.
Mrs. Mendoza, who has had type 2 diabetes for 17 years, had a below-the-knee amputation of her gangrenous left foot.

The two basic components of type 2 diabetes are _________. (select all that apply)
Answer:
The correct answer is - Type 2 diabetes mellitus has major components: insulin resistance and impaired insulin secretion.
Explanation:
In type 2 diabetes there are two major components that play an important role to cause this that are Insulin resistance in which insulin could not bind with the specific receptors that result in less effective at stimulating glucose uptake.
The other major component is impaired insulin secretion in which an increased amount of insulin is required that there is not enough insulin to prevent the breakdown of fats and production of ketones.
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?
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.
