Micrograms In Nursing
Nurses also use ratios and proportions when administering medication. Nurses need to know how much medicine a patient needs depending on their weight. Nurses need to be able to understand the doctor’s orders. Such an order may be given as: 25 mcg/kg/min. If the patient weighs 52kg, how many milligrams should the patient receive in one hour? In order to do this, nurses must convert micrograms (mcg) to milligrams (mg). If 1mcg = 0.001mg, we can find the amount (in mg) of 25mcg by setting up a proportion.

By cross-multiplying and dividing, we see that 25mcg = 0.025mg. If the patient weighs 52kg, then the patient receives 0.025(52) = 1.3mg per minute. There are 60 minutes in an hour, so in one hour the patient should receive 1.3(60) = 78mg. Nurses use ratios and proportions daily, as well as converting important units. They have special “shortcuts” they use to do this math accurately and efficiently in a short amount of time.

White blood cell counts are generally given as a numerical value between 4 and 10. However, a count of 7.2 actually means that there are 7200 white blood cells in each drop of blood (about a microlitre). In much the same way, the measure of creatinine (a measure of kidney function) in a blood sample is given as X mg per deciliter of blood. Doctors need to know that a measure of 1.3 could mean some extent of kidney failure. Numbers help doctors understand a patient’s condition. They provide measurements of health, which can be warning signs of infection, illness, or

    The nurse would plan suitable charts and regimes for the patient to follow. Intake and output are measured. IV fluids and electrolytes are administered as prescribed, and oral fluid intake is encouraged when it is permitted. Vital signs are monitored hourly for signs of dehydration (tachycardia, orthostatic hypotension) along with assessment of breath sounds, level of consciousness, presence of oedema, and cardiac status. If the patient agrees with the diet plan and increases his fruit and vegetable intake this can highly optimise nutritional health, promote a healthy image and reduce the chances of obesity (Lock et al., 2005). In Diabetes, diet is a chief obstacle in the control of the condition (Watson et. al 1997). The patient’s goals in agreeing with a healthy diet for their Diabetes are as follows: 1) To regulate and sustain lipid levels and blood glucose back to their normal state. 2) To avoid fluctuations in their blood glucose levels during the day. 3) To manage and control a desirable body weight. 4) To prevent or hinder the growth or advancement of renal, neurological or cardiovascular difficulties (Watson et. al 1997). The nurse should introduce a dietary plan for the patient with the Diabetes. This controls the amount of calories that are needed for each day and the magnitude of these calories to be assigned to carbohydrate, protein…

    What is the significance of a lower-than-normal hematocrit? What is the effect of a bacterial infection on the hematocrit? A lower than normal hematocrit indicates anemia, a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to the body tissues. If you have a bacterial infection, your white blood cell count would increase because as the wbc's are fighting off the infection they die off releasing a chemical into the blood stream that tells your body to increase production of white blood cells. With a higher production of white blood cells the red blood cell production would slightly decrease which would decrease the ratio of rbc’s to whole blood volume.…

    The Pediatric Trauma Room is armed with state of the art life-saving equipment that is used daily in the treatment of emergent and critical patients. The pediatric population differs from the adult population primarily because treatments and medication dosages are based on the patient’s weight (Emergency Nurses Association [ENA], 2012). Recording incorrect weights for the pediatric population in the Emergency Room can cause harm and can potentially cause death or permanent damage beyond that of their original emergent ailment/ incident. Pediatric medication errors are considered the most common and also the most avoidable (ENA, 2012). Obtaining the pediatric patient’s correct weight is considered an integral and mandatory element of the nursing assessment (ENA, 2012). The ability to obtain that weight quickly and accurately is of the upmost importance in an emergent situation. Presently a length-based tool called the Broselow Pediatric Emergency Tape is utilized to estimate the pediatric patient’s weight in emergent…
