A scientist did a test to compare two substances: substance Q and substance R. At room temperature, both substances are liquid. When the scientist transferred the same amount of energy out of both substances, only one substance changed phase while the other did not. Which substance changed phase, and how did it change?

Answers

Answer 1

Based on the information given, it is not possible to determine which substance changed phase or how it changed.

How do you know the one that changed phase?

We have to know that the change of phase is one of the processess that would occur when we increase the temperature of the system and this can be done by the addition of heat to the material.

We do not have the heating curve of the substances hence it would be difficult to know which of the substances that is going to change phase. This information is easily read off from the heating curve.

Based on the medical information, it can be inferred that the dose for the patient weighing 120 pounds would be 2.1 mL. Additionally, the patient will receive 8 mL of Furosemide every 24 hours.

How to find the amount of medication dose?

To find the amount of the drug dose we must follow the following procedure:

1. We must identify the relevant information to solve the problem:

Prescription: Digoxin 10 mcg/kg per dayPatient weights: 120 lbs

2. We must calculate how many kilos are equal to 120 pounds.

1 pounds = 0.45 kilograms120 pounds = 54.43 kilos

3. We must calculate the dose that the nurse should give the patient.

If you weigh 54.43 and it is 10 mcg/kg per day, then we must multiply these values:

54.43 * 10 = 544.3

4. We must calculate how many mL this dose is equivalent to.

So we know that 500 mcg /2 mL544.3 * 2 / 500 = 2.1 mL.

According to the above, the dose would be 2.1 mL

On the other hand, to calculate how many mL will the patient receive in 24 hours we have to make the following procedure:

24 / 6 = 44 * 60 mg = 240 mg240 / 30 = 8 mL

You need 50 mL of a 10% boric acid solution. The pharmacy carries only85% boric acid.
How much concentrate will you need?

Answers

Explanation:

To determine how much 85% boric acid concentrate you need to make 50 mL of a 10% boric acid solution, you can use the following formula:

concentrate needed (mL) = desired concentration * volume / desired strength

Plugging in the given values, you get:

concentrate needed (mL) = 10% * 50 mL / 85%

Simplifying, you get:

concentrate needed (mL) = 0.12 mL

So, you will need about 0.12 mL of 85% boric acid concentrate to make 50 mL of a 10% boric acid solution.

Doctors often strike your knee gently with a rubber hammer and see if your leg gives a little kick as part of a routine physical. This patellar reflex test is literally looking for a knee jrk response, one that you are not thinking about at all! What do you think the doctor is testing here
what part of the body would this test examine? What would an abnormal result look like, and why is it important to detect abnormal results? How might a patient’s response change as they enter old age, as opposed to when we are tested as children?

Answers

The patellar, or knee-jrk, reflex is what the doctor feels when tapping your knee. Because the doctor is actually tapping on a tendon called the patella tendon, it is also known as a deep tendon reaction.

What is patellar?

In order to extend your knee so that you may run, jump, and kick, the patellar tendon collaborates with the muscles in the front of your thigh.

The majority of patellar tendinitis cases, often known as rider's knee, occur in athletes who participate in sports like basketball and other sports that frequently require hopping.

Patellar tendonitis, sometimes referred to as rider's knee, is a condition marked by inflammation of the tendon.

Numerous conditions necessitate a patellarectomy, such as severe osteoarthritis of the knee, anterior knee discomfort, or a comminuted patellar fracture.

Thus, it important to detect abnormal results.

Is a relatively common birth defect in which a testicle typically descends on its own within a few months of birth

Answers

It sounds like you are describing undescended testicles, also known as cryptorchidism. It is a relatively common birth defect in which one or both of the testicles do not fully descend into the scrotum. In most cases, the testicles will descend on their own within a few months of birth, but in some cases, surgery may be needed to move the testicles into the correct position.

Undescended testicles can affect fertility and increase the risk of testicular cancer, so it is important for boys with this condition to be monitored and treated as needed. In some cases, hormone therapy may be used to stimulate the descent of the testicles, and in more severe cases, surgery may be necessary to move the testicles into the correct position.

The doctor is testing for the neurological function of the individual.

The part of the body that this test would examine is the nervous system of the body.

An abnormal result would have a long response time or no response at all and is it important to detect abnormal results because it will help to know how well the individual's reflex is working in order to help avoid dangerous situations.

A patient’s response will take longer and gradually reduce in strength as they enter old age, as opposed to when we are tested as children.

What is a patellar reflex test?

The patellar reflex test, which assesses the integrity of neurological function, involves striking the patellar tendon beneath the kneecap with a test hammer.

Reflex actions are involuntary actions, hence, the faster the reflex of an individual, the more functional the nervous system of the individual is.
