500 Questions

What blood type can a person with AB blood type receive?

User Avatar

Asked by Wiki User

The short and sweet answer is no, they cannot. The reason behind it is because AB blood also has the antigens of B blood and since B and A are unmixable, AB and A is as well. Now Type A blood and give to type AB blood since A is in the name. A good rule of thumb with donations is that if your blood type is the other persons blood type then you can give to them. The exception is O in which case you can give to any type as long as they match + or -. However O can only receive from O. It is rather confusing but it boils down to this.

  • A gives to A and AB
  • B gives to B and AB
  • O gives to A, B, and AB
  • A can receive only A and O
  • B receives B and O
  • O receives only O
  • AB receives all

Now the above list is correct except that...You match your positive or negative signs as well. There you have it.

What lab test for the elderly would measure amount of free unbound drug molecules?

User Avatar

Asked by Wiki User

The lab test that measures the amount of free unbound drug molecules in the blood is called "free drug concentration" or "free drug level." This test is particularly important for the elderly as changes in kidney or liver function can alter the metabolism and clearance of medications, leading to potential drug toxicity or inadequate treatment. Monitoring the free drug concentration helps healthcare professionals optimize drug dosing and minimize the risk of adverse effects in older adults.

How do hospital workers use math?

User Avatar

Asked by Wiki User

Hospital workers use math in various ways. They use it to calculate medication dosages based on a patient's weight and age, to interpret and analyze medical test results, and to manage and allocate resources efficiently. Math also helps in making predictions and forecasts based on patterns and trends, such as predicting patient flow and demand for services.

Can you drink coffee before a blood test requiring 12 hour fast?

User Avatar

Asked by Wiki User

No, it is generally recommended to avoid consuming anything except water during a 12-hour fast before a blood test. Coffee contains caffeine and other compounds that can affect your blood test results, so it is best to abstain from it until after the test is complete.

How do you collect a sample?

User Avatar

Asked by Wiki User

In a variety of industries, including healthcare, research, and quality control, gathering a sample is an essential step. The kind of sample and its planned usage will determine the precise method. I'll include some general suggestions for gathering samples here:

Make sure you have the essential supplies, such as sterile containers, swabs, or collecting tubes, before you start. If necessary, put on the proper personal protective equipment (PPE), such as gloves, a mask, and lab coats.

Choosing the Sample Type: Decide what kind of sample you need to take—blood, urine, tissue, swabs, or something else. Use the appropriate container and collection technique for that sort of sample.

Patient Preparation: If you're taking a sample from a person, make sure they understand the process and get their agreement. Patients may occasionally need to adhere to particular dietary or pharmaceutical restrictions prior to sample collection.

Sample Gathering Procedure:

Blood: To collect blood, a sterile needle is often inserted into a vein, typically in the arm, and the necessary amount of blood is drawn into a collecting tube. A certified phlebotomist or medical professional performs this task.

In order to collect mid-stream urine samples, provide the patient a clean container and instructions. The patient should correctly fill and seal the container.

Swabs: Swabs are frequently used to take samples from surfaces, injuries, or mucous membranes. Use a sterile wipe to clean the area of interest

Tissue or Biopsy: The acquisition of tissue or biopsy sample may need surgical procedures. This will be done by a surgeon or other medical professional who will make sure aseptic procedures are followed.

Saliva: Spitting into a collecting tube is the easiest way to collect saliva. Make sure the person fasts for a certain amount of time before being collected.

Stool samples may be required from patients for a variety of examinations. They take the sample in a pristine, single-use container.

Why do a ECG on a head injury patient?

User Avatar

Asked by Wiki User

Although electrocardiography (ECG) on a patient with a head injury may not appear immediately pertinent, it is crucial for the overall assessment and management of these cases. Why an ECG is crucial for people with head injuries is as follows:

Rule out Cardiac Causes: If a head injury is severe or is coupled with chest trauma, it may occasionally result in cardiac problems, such as arrhythmias (abnormal heart rhythms). An ECG aids in eliminating any potential heart issues that may be causing the patient's symptoms.

Recognize Stress-Related Changes: Severe head trauma can result in physiological stress reactions that may have an impact on the heart. An ECG can detect these stress-related alterations, and being aware of them is essential for the patient's overall care.

Check for the vasovagal response. Some people who have had a head injury may have the vasovagal response, which causes a sharp drop in heart rate and blood pressure. It's crucial to recognize and control this response as soon as possible because it can cause syncope (fainting) and additional harm.

Medication and sedative: For pain management, imaging, or other interventions, patients with head injuries may occasionally need medication or sedative. ECG monitoring is crucial to ensure the patient's safety because these medications have the potential to influence the heart's electrical activity.

Assess Oxygenation: Serious head traumas can impair the brain's ability to get oxygen, which may have a knock-on effect on the heart. An ECG can be used to assess the patient's overall level of circulation and oxygenation.

Why blood for testing is drawn from left ring finger?

User Avatar

Asked by Wiki User

I have had multiple blood draws done every year since the middle 1990s and the blood has always been taken from veins in my forearm (sometimes left, sometimes right) near the elbow, never the hands or fingers.

Diabetic blood sugar tests are often taken from the fingertips, but there is a tendency for many new test devices to get away from this and use the arm because the fingertips are more pain sensitive than the arms.

I cannot think of any reason a blood test would have to be taken only from a single finger.

If a Mother is b positive blood group and a Father is A positive blood group can they have a child that is O negative blood group?

User Avatar

Asked by Wiki User

No. For a child to have AB, one parent must have either A or AB and the other must have B or AB. O is a recessive type to both, so neither parent has any of those bloodtypes; their child will be O.

Spinning an egg to see if it is boiled or uncooked- if it is wobbly, it is uncooked. otherwise, it is not.

Immersing an egg in cold water to see if it is fresh or old- if it floats it is old, if it sinks it is fresh.

Adding yeast to bread dough and covering the dough with cloth and leaving it alone for a few hours before baking- the cloth keeps insects from contaminating the dough and the yeast creates small holes in the dough filled with carbon dioxide making the bread rise.

What are the causes of a high neutrophil count in cats?

User Avatar

Asked by Wiki User

Inflammation and infection are the causes of high neutrophils (white blood cells) in cats. The neutrophils eat 'enemy' cells like a little Pac-man, and die off after a day.

Tooth and kidney infections or cancers are common causes of high counts in older cats. Your veterinarian's review of the other items in the blood and urine tests can help determine which antibiotic or course of treatment will work best. Often it is as simple as a week-long course of Amoxicillan twice a day (the same bubble-gum pink stuff you got yourself as a kid).

A low neutrophil count is often a sign of leukemia, since the cat's body is not replenishing its daily supply of neutrophils. The cat will be more susceptible to infections of all types and will not be able to fight it off like normal.

What is the normal range of creatinine level in adult urine?

User Avatar

Asked by Wiki User

Normal random urine creatinine levels range from 40 to 300 mg/dl but it should be kept in mind that this range is somewhat dependent on the individual's sex, age and if there are other mitigating factors. The range is typically adjusted based on a few outside factors, but 40 to 300 is a pretty good "all-purpose" range for URINE, not serum.
