A PCP might use social media to report laboratory results to a patient.

Answers

Answer:

False

Explanation:

A PCP might use social media to remind everyone to get a flu shot, but they can't share your medical records with the public due to HIPAA laws.

The statement "A PCP might use social media to report laboratory results to a patient" is absolutely false.

What is Social media?

Social media may be defined as such types of websites and applications that allow the users to construct and share content, information, ideas, interests, and other sorts of expression through virtual communities and networks.

PCP stands for Primary care provider. A PCP never shares the reports of laboratory results to a patient on social media without the actual consent of the pateint.

This is because sharing the tests and medical reports of any patient on social media is against the HIPAA rule. So, without the actual consent of the patient, a PCP never discloses the results of medical reports to their relatives or family members as well.

Therefore, the statement "A PCP might use social media to report laboratory results to a patient" is absolutely false.

A vial of streptomycin sulfate is to be reconstituted for IM injection in
a hospitalized patient. The vial contains 5 g of the medication. The
instructions say to add 9 mL of sterile water; this results in a
concentration of 400 mg/mL. What is the volume of the dose in mL
needed to fill a doctor's order for 500 mg daily?
1.25 mg
1.25 L
1.25 mL
1.25 mg/ml

Answers

Answer:

Explanation:

9 mL contains 400 mg/ mL

If you want a dose of 500 mg you would need to take 1.25 mL of the dilute solution.

This problem couldn't be more deceptively worded. The only fact you can rely on is the concentration becoming 400 mg / mL

You come to the answer by figuring out how to get 500 mg.

400 mg / mL * x = 500 mg      Divide by 400 mg / mL. Watch the units.

x = 500 mg// 400 mg / mL      The mg cancel out.

x = 1.25 mL

if we do not wash our eyes regularly, what can happen to our eyes?

Answers

if we do not wash our eyes regularly, what can happen to our eyes?

Protection against Bacteria

Whenever we walk out in the open, we are always exposed to high levels of dust and bacteria. These microorganisms can prove to be extremely harmful to eyes. Most Americans do not have a habit of cleansing their eyes. No matter how much you care for your eyes, tiny bacteria will always be resting on your eyelids and eyebrows. Cleansing eyes with cold water just before going to bed can be of great help in removing those bacteria. Eye cleansers are available on almost every cosmetic store.

Allergens

Do you have dust allergies? Are you someone who gets itchy eyes after moving out in the open? If yes, then you surely need to discipline your hygiene. There are several allergy symptoms of allergies in your eyes such as mold, pollen eyes, etc. Make sure that you keep a small towelette so that you can wipe your eyes whenever you feel that are tiny signs of itching or redness. In case you have severe eye allergies then you can get LASIK eye surgery New Jersey to get rid of the issue.

Immunity against makeup

Aesthetics have become a major part of our routines. Putting on contact lenses for a genuine eye sight issue or merely to join the fashion bandwagon has become very common. The number of times that you touch your eyes is directly related to how many times you are putting so many bacteria in the sensitive place. Protection can be enhanced if you clean your brushes and makeup products regularly. Moreover, it is also imperative that you don’t use products that have been personally used by others.

Competitive eyesight

Many people across the world are suffering from the issue of having weak eyesight. For many people it is genetically an issue; however there are many others whose lifestyle results in them having weaker eyesight. Taking care of the eyes with simple steps such as not directly facing the skin, keeping yourself away from television, not using mobile phones and gadgets will all protect the eyes from this chronic issue.

Lastly, we cannot overlook the fact that our eyes play a very crucial role in our lives. Keeping eyes clean will not only protect them in the short run but will help us in the long run. Moreover, had it not been for our eyes then we would never have been able to see this beautiful world........

Answers

Answer:

mesosystem

Explanation:

Bronfenbrenner's ecological systems theory is a meta-theory focused on a child's development. This theory indicates complex environmental 'layers' that have an effect on a child's development. Bronfenbrenner categorizes a person's environment into five systems: 1-microsystem (i.e., direct contact with the child, e.g., parents and siblings), 2-mesosystem (i.e., interactions between the microsystems in one's life), 3-exosystem (i.e., social structures that indirectly influence child's development), 4-macrosystem (i.e., cultural context), 5-chronosystem (i.e., transitions and shifts that influence development). A mesosystem comprises interactions between the microsystems in which the developing individual participates. In consequence, a girl’s face-to-face interaction with her siblings is part of her mesosystem because siblings form part of her microsystem and they have a direct influence on her development.

What type of receptor detects changes in blood pressure? A. Osmoreceptor B. Thermoreceptor C. Baroreceptor D. Adrenoreceptor

Answers

The answer to the question is the option
C. Baroreceptor

Baroreceptor located in the carotid sinuses and the aortic arch detects changes in blood pressure. Therefore, option C is correct.

What is baroreceptor?

Mechanoreceptors known as baroreceptors enable the autonomic nervous system to communicate information derived from blood pressure. After that, information is transmitted quickly in order to change the cardiac output and total peripheral resistance, keeping the blood pressure within a predetermined, normal range.

Baroreceptors come in two varieties: low-pressure volume receptors and high-pressure arterial baroreceptors, both of which are triggered by the stretching of the vessel wall. Carotid sinuses and the aortic arch both include arterial baroreceptors.

It can detect changes in blood pressure. Thus, option C is correct.
