A formula for ivy cream includes 3 g of hydrocortisone in a total of 60 g of ointment. If an order calls for 45 g of this ointment, how much hydrocortisone will be needed?

Answers

Answer:

Explanation:

This is just a proportion.

3 grams hydrocortisone                 x    

======================    =  ==============

60 grams of ointment               45 grams of ointment

3/60 = x / 45               Cross multiply

45 * 3 = 60 * x             Combine the left.

135 = 60* x                  Divide by 60

135/60 = x

x = 2.25 grams of hydrocortisone.

Answers

Added sugar in a meal should be less than 10% ( A ) of the total carbohydrate of a food item

Importance of carbohydrates

Carbohydrates in the human body is a source of energy which helps with the performance of daily routine by individuals. Carbohydrates are first broken down into glucose before absorption into the blood stream.

Since carbohydrates are broken into glucose the added sugar in a meal should be less than 10% of the total carbohydrate in the food.

Hence we can conclude that Added sugar in a meal should be less than 10% ( A ) of the total carbohydrate of a food item.

Answers

Answer:

This question lacks options, options are:

A. increase the synthesis of contractile protein in muscle.

B. promote long bone growth.

C. favor the mobilization of FFA and reduces tissue use of blood glucose.

D. none of the above.

The correct answer is A.

Explanation:

Plasma concentration is the amount of a substance (hormones, glucose, proteins, among others) that circulates in the blood. The main action of growth hormone is to stimulate protein synthesis, through the mobilization of amino acid transporters, in a manner analogous to glucose and insulin transporters. In addition to stimulating protein synthesis, the growth hormone simultaneously mobilizes fat by direct lipolytic action. The processes of muscle protein synthesis and muscle protein breakdown occur simultaneously. This constant turnover of proteins allows the muscle fibers to modify their structure when the demands of loads or food vary. The plasticity of skeletal muscle in responding to changing loads or contraction patterns is evidence of the ability to remodel present in fibers. While resistance exercise significantly stimulates the synthesis of muscle contractile (myofibrillar) proteins, resistance exercise will have a greater impact in stimulating mitochondrial protein synthesis, thus allowing a specific muscle adaptation to exercise.

dehydrated, and doesn't have any vomiting or diarrhea.
Use this information to calculate the needed fluid rates
for each phase of fluid therapy for this patient. Be sure
to include the formula you're using, and show each step
in the calculation of the fluid rates.

Answers

Answer:

The correct answer would be - rehydration dose of 360 ml

Explanation:

Rehydration dose or hydration deficit is amount of fluid that required to be replaced to bring a dehydrated animal to hydrated state.

Given:

8 lbs cat 10% dehydrated   (without vomiting or diarrhea)

8 lbs = 3.6 kg

Formula:

rehydration dose (ml) = (% dehydration X Body Weight in kg) X 1000

convert % to a decimal - ex 10% = 0.1

solution step by step :

total ml for rehydration =

(0.1 x 3.6 kg) X 1000 =

0.36 x 1000 =

360 ml rehydration dose

first 24 hours

= 360 X 0.8 = 288 ml

second 24 hours

= 360 X 0.2= 72 mls

The needed fluid rates for each phase of fluid therapy for this patient will be 288ml and 72 ml.

Based on the information given, the total ml that's needed for rehydration will be:

= 10% × 3.6 × 1000

= 360 ml

Therefore, for the first 24 hours, the fluid rate will be:

= 369 × 0.8

= 288 ml

For the second 24 hours, the fluid rate will be:

= 366 × 0.2

= 72 ml

Therefore, the needed fluid rates for each phase of fluid therapy for this patient will be 288ml and 72 ml.

Regarding mechanical ventilation, what ventilator settings are the primary determinants of oxygenation?

The ventilator is not called a magical therapy that provide relaxation to the patient but now it is a simple supportive therapy that help a patient to get up well soon.

Explanation:

Ventilation is used when a patient have hypoxemia and when increased the work before the breathing. The main goal of ventilator is to provide the oxygenation and ventilation to the patients. It reduces the lung injury during ventilation.

Oxygenation is a process that controlled by the positive end expiratory pressure and the fraction in the inspired oxygenation. It also controlled by RR and Vt. There is the fact that help us to understand the mechanical ventilator but later on it limited our understanding the advanced modes of machine.

Answer:

Ventilator are machines to provide mechanical ventilation to a patient, it works by moving air into and out of the lungs  and delivering breaths to the patient if he/she is unable to breathe or having breathing difficulty.

[tex]FiO_2[/tex] and mean airway pressure are two factors that determine oxygenation.  

The average pressure your lung is exposed to during inspiration and expiration during mechanical ventilation is called mean airway pressure.

Lenco Industries has cost of goods manufactured of $65 000 in May. The finished goods inventory at the end of May was $20 000 and the cost of goods sold during May was $75 000. The inventory in finished goods at the beginning of May was: $5000. $30 000. $10 000. $20 000

Answers

Answer:

The correct answer is:

$30,000

Explanation:

ending inventory = $20,000

sales = $75,000

Manufactured goods = $65,000

Beginning inventory = ???

1. First let us calculate the difference between the cost of goods sold and the cost of goods manufactured, in order to determine the goods from alternative sources order than manufacturing. This is done as follows:

Goods from sources other than manufacturing = (sales) - (manufactured goods)

Goods from sources other than manufacturing = 75,000 - 65,000 = $10,000

This means that out of the $75,000 worth of goods sold, $10,000 was from a source other than manufacturing which can be accurately predicted to be the beginning inventory

2. Next, to calculate the total beginning inventory, we will add the goods sold from the beginning inventory and the ending inventory.

Beginning inventory = (Goods from sources other than manufacturing ) + ending inventory

Beginning inventory = 10,000 + 20,000 = $30,000

Note, since the sales are more than the manufactured goods, the excess is from beginning inventory
