Answer:

D. the patient has a phechromocytoma (an over-secreting tumor of the adrenal medulla)

C. T4 = High, TSH = Low, Thyroid-Stimulating Antibodies = High

B. Secretion of FSH in postmeopausal women is low.

Explanation:

The glucose test of the patient is normal, the patient has no symptoms of diabetes. The patient has phechromocytoma which is rare tumor of adrenal gland tissue. This results in release of hormones which control heart and blood pressure.

The patient diagnosed with grave diseases has lots of Thyroid Stimulating Antibodies. Higher antibodies suggest that the patient has thyroid with immune system. Grave disease has high T3 and T4 while TSH is low.

Secretion of FSH in postmenopausal women is high. The frequent soaking in hot tubs can increase male fertility.

For a 2,000-calorie diet, how many cups of milk or the equivalent per day does myplate recommend?
sergij07 [2.7K]

3 cups of milk, or the equivalent, per day are advised for only a 2,000 caloric diet, according to My-Plate.

My-Plate recommendation:

  • According to My-Plate recommendation, the dairy category covers dairy products such as milk, yogurt, cheese, lactose-free milk, fortified soy milk, and yogurt. It excludes dairy products with high fat and low calcium content including cream cheese, sour cream, cream, and butter.
  • Human age, height, weight, degree of physical activity, and the quantity of dairy required will all affect how much you need. The quantity for women may also change depending on whether they are nursing or pregnant. My-Plate study shows that about 90% of Americans do not consume enough dairy, thus most people would benefit from increasing their diet of fat-free or low-fat dairy products, whether they come from milk (including lactose-free milk), yogurt, or cheese.

Select all of the following that are found in cardiac muscle but not in skeletal muscle.
svetlana [45]

Answer: the following are found in cardiac muscle except skeletal muscle. intercalated discs and gap junction. The correct option is C and E.

Explanation:

There are three different type of muscles,

Smooth muscle

Skeletal muscle and

Cardiac muscle.

The cardiac muscle contains intercalated discs and gap junction which is absent in skeletal muscle.

Intercalated discs contain gap junctions and desmosomes. The gap junctions, which are protein-lined tunnels, allow direct transmission of the depolarizing current from cell to cell, across the chambers of the heart, so that the cells contract in unison.

A premature newborn weighing 1950 grams has an order to receive 25 ml fortified human breast milk by gavage tube every 3 hours.
brilliants [131]

Answer:

6.76 ounces daily.

Explanation:

There are 0.0338 ounces in 1 ml of the fluid.

So the calculation is as follows.

Ounces in 1 ml of fortified human breast milk = 0.0338

The amount in ml of fortified human breast milk recieved by a premature newborn every 3 hour = 25 ml

Total hours in one day = 24

The amount in ml of fortified human breast milk recieved by a premature newborn every day = 8 * 25 = 200 ml

(As 3 hrs is multiplied by 8 to make it 24 hrs (a day))

The amount in ounces of fortified human breast milk recieved by a premature newborn every day = 200 ml * 0.0338 = 6.76 ounces.

(As 1 ml contains 0.0338 ounces)

Hence the baby will recieve 6.76 ounces of milk each day.

Name 2 causes of respiratory compromise (2 reasons why someone couldn’t breathe adequately)?
FinnZ [79.3K]

Answer:

1. Airway Blockage/Obstruction

2.Scarred lung tissue

Explanation:

If your airways are blocked by anything ranging from mucus to a tree sapling (this can happen lol), it will prevent you from breathing normally, and it will be harder for you to take a breath after exercising, for example. Scarred lung tissue is an issue that comes from pre-existing conditions, such as asthma, and what happens with this is that, due to so much strain on your lungs, they can get injured or collapse, and after some time, the injuries on the tissue will cause it to harden, which means your lungs will not be able to expand and contract properly.
