What does Cannell consider to be the primary physiological constraint on the ability of giant dragonflies (from the Permian era) to fly and hunt prey (
"
According to Cannell, the primary physiological constraint on the ability of giant dragonflies to fly and hunt prey was respiration. The tracheal system of insects is not very efficient at delivering oxygen to large body sizes, so as dragonflies grew larger, they would have had to breathe more rapidly to meet their oxygen demands.
This would have put a strain on their respiratory system and made it difficult for them to fly and hunt prey.
Cannell's findings are supported by the fact that the largest dragonflies ever known lived during the Permian period when the oxygen concentration in the atmosphere was much higher than it is today.
As the oxygen concentration in the atmosphere decreased, so did the size of dragonflies.
In addition to respiration, Cannell also considered other factors that could have limited the size of giant dragonflies, such as their heart and circulatory system, their muscle mass, and their exoskeleton. However, he concluded that respiration was the most likely limiting factor.

To avoid muscle injury, strength training should be done no more than
a. once a week
b. two to three times per week
c. three to four times per week
d. strength training can be done every day
To avoid muscle injury and allow for proper recovery, it is generally recommended to engage in strength training exercises two to three times per week. This frequency allows for sufficient stimulus to promote muscle growth and strength gains while also providing adequate rest and recovery time for the muscles.
Strength training involves stressing the muscles through resistance exercises, which can lead to microscopic damage to the muscle fibers. The recovery period is essential for the muscles to repair and rebuild stronger. If strength training is done too frequently without adequate rest, it can increase the risk of overuse injuries, muscle fatigue, and impaired performance.
While it is possible to engage in strength training every day, it is not typically recommended for most individuals, especially beginners or those without prior experience. Giving the muscles time to rest and recover between sessions allows for optimal results and helps prevent overtraining.
It's worth noting that the specific frequency of strength training may vary depending on factors such as individual fitness goals, training intensity, and the specific muscles being targeted. Consulting with a qualified fitness professional or personal trainer can provide personalized guidance based on individual needs and abilities.

which lab result is a priority for the nurse to assess for a client who is prescribed dantrolene (dantrium)?
The lab result that is a priority for the nurse to assess for a client who is prescribed dantrolene (Dantrium) is the liver function test.
Dantrolene is a medication used to treat muscle stiffness, muscle spasms, and muscle spasticity that can occur after a spinal cord injury, stroke, or multiple sclerosis.
Dantrolene sodium (Dantrium) is a medication used to treat muscle stiffness, muscle spasms, and muscle spasticity that can occur after a spinal cord injury, stroke, or multiple sclerosis. Dantrium belongs to a group of medications known as muscle relaxants.
The nurse should prioritize the assessment of liver function tests since dantrolene has been linked to hepatotoxicity. Elevated liver function tests, such as increased ALT or AST, are indications of hepatotoxicity. For clients who have had chronic liver disease or abnormal liver function, Dantrolene should be used with caution because it is metabolized in the liver.
When administering Dantrium, the following must be considered:
Monitor liver function regularly as it may cause liver damage, Monitor lung function in clients with a history of chronic obstructive pulmonary disease (COPD), and Observe for muscle weakness, dysphagia, and aspiration to ensure that the client's airway remains open (Fritschi & Quinn, 2019).

for a hot or cold therapy to be effective, the pack should be applied for how long to the injured area?
For a hot or cold therapy to be effective, the pack should be applied for 20 minutes in every 2 hours to the injured area.
The blood vessels constrict as a result of the cold therapy, reducing circulation and so reducing pain. The veins enlarge as the cold is removed, boosting circulation. Heat therapy can be used to promote blood flow and the inflow of nutrients that will help mend the damaged tissues. Every two hours for a few days, the therapy can be repeated after being applied for roughly 20 minutes the first time. The swelling and inflammation will go down at that point, and the injury should be well into the healing process. Always cover the pack with a small towel to help preserve your skin whether you use heat or cold. Apply to the sore spot several times a day for 15-20 minutes at a time. You might notice that after applying the compress, your skin appears a little pinker, whether you used heat or cold.

for a patient with acute angle-closure glaucoma, which topic is appropriate to include in discharge teaching? a. instillation of timolol (timoptic) eye drops b. use of promethazine (phenergan) for nausea, as needed c. application of an eye patch for comfort d. return to a weight-lifting exercise program
a. instillation of timolol (timoptic) eye drops. The primary focus of discharge teaching for a patient with acute angle-closure glaucoma should center on the use of medications to reduce intraocular pressure.
Instillation of Timolol (Timoptic) eye drops is an appropriate topic to include in discharge teaching, as this medication is commonly prescribed to reduce intraocular pressure and to treat the condition.
Promethazine (Phenergan) may be used to manage nausea as needed, but this should not be the primary teaching point. Application of an eye patch may be recommended for comfort, but this should not be the main teaching point either.
Return to a weight-lifting exercise program should not be recommended at this time, as the patient should be advised to avoid any strenuous activity or activities that could increase intraocular pressure. Therefore, instillation of Timolol (Timoptic) eye drops should be the primary focus of discharge teaching for a patient with acute angle-closure glaucoma.

because she has had a mastectomy. She indicates that her lymph nodes were also removed on
that side and the doctor told her not to have her blood pressure taken on that side. Why would a
doctor say this? You may need to refer to the Internet for the reason why
Answer:
Its precautionary to prevent lymphedema.
Explanation:
Sometimes, removing lymph nodes can make it hard for your lymphatic system to drain properly. If this happens, lymphatic fluid can build up in the area where the lymph nodes were removed. This extra fluid causes swelling called lymphedema.
The surgical partial or total removal of one or both breasts is referred to medically as a mastectomy. Breast cancer is typically treated with a mastectomy. Women who are thought to have a high risk of developing breast cancer occasionally have the procedure done as a preventative step.
What is Lymphedema?Lymphedema is caused by a blockage in the lymphatic system. This is usually the result of a traumatic event, such as a sports injury or deep cuts and bruises, or as a side effect of surgery or cancer treatment. Lymphedema can occur as a birth defect or as a symptom of infection in rare cases. Precautions are required to prevent lymphedema. When lymph nodes are removed, your lymphatic system may struggle to discharge properly on occasion. If this occurs, lymphatic fluid may accumulate where the lymph nodes were removed. Lymphedema is a swelling caused by extra fluid. It is critical to understand that lymphedema can sometimes become severe and cause serious problems, and that it is frequently a long-term or chronic condition.To learn more about Mastectomy refer to:

Cardiocytes and skeletal muscle differ over which part of myofibril structure?
Cardiocytes and skeletal muscle differ over titin part of myofibril structure.
Myofibrils are composed of long proteins as well as simple protein, myosin, and titin, and alternative proteins that hold them along. These proteins are organized into thick, thin, and elastic myofilaments, that repeat on the length of the sarcostyle in sections or units of contraction known as sarcomeres.
Cardiomyocytes contain several sarcosomes, which give the desired energy for contraction. in contrast to striated muscle cells, cardiomyocytes unremarkably contain one nucleus. Cardiomyocytes typically contain constant cell organelles as striated muscle cells, though they contain additional sarcosomes.

A client is admitted with a diagnosis of diabetic ketoacidosis. An insulin drip is initiated with 50 units of insulin in 100 ml of normal saline solution. The I.V. is being infused via an infusion pump, and the pump is currently set at 10 ml/hr. How many units of insulin each hour is this client receiving
Answer:
5 units
Explanation:
We are told in the question that the insulin drip given to the patient is:
50 units of insulin = 100 ml of normal saline solution
The infusion pump is set at :
10 ml in = 1 hour
The number of units of insulin that the patients receives each hour is calculated as:
100 ml of normal saline solution = 50 units of insulin
10 ml = X units of insulin
Cross Multiply
100ml × X = 50 units × 10 ml
X = 50 units × 10ml / 100ml
X = 5 units.
Hence 10 ml of normal saline solution contains 5 units of insulin.
Therefore, the number of units of insulin that the patients receives each hour is 5 UNITS
