- atrophine inhibits parasympathetic activity. when it's given to a patient, their heart rate will - stay the same - increase - decreasePlease help me I do not get thia and what is the process of how a pulse passes through a nerve cell?Hello, I do not understand these questions, can I get help with them, please? Below are 3 statements, explain if each is true/false and why (VERY brief statement) #1: A tropic hormone always increases the size of an endocrine gland. #2: Spontaneous action potentials in the heart are primarily triggered by flux of K+ into cells through If channels. #3: Increasing the frequency of action potentials in motor units generates more tension than increasing the number of motor units.
- A client weighs 165 lbs. The physician orders dopamine 400 mg/500 mL D5W at 5 mcg/kg/min to start and titrated to 10 mcg/kg/min to stabilize blood pressure.

She has previously used Epipen but has been prescribed Jext this time. 1 What differences are there between the brands? 2Can you swap between each brand of adrenaline? 3 Would you need to have a conversation with the prescriber?Dexamethasone 1 Dexamethasone is a glucocorticoid administered as an anti-inflammatory agent and immunosuppressant. It is structurally similar to cortisol produced naturally by your adrenal glands. It treats a number of conditions including inflammation, arthritis, autoimmune conditions, skin and eye conditions, asthma, multiple sclerosis, blood or bone marrow disorders, different types of cancer (e.g. leukemia and lymphoma), and severe allergies.

- The drug atropine inhibits the action of the parasympathetic system on the heart We would therefore expect that atropine would Increase cardiac output Decrease BP Increase HR Decrease release of epinephrine ✓ [Choose ] True False [Choose ] [Choose ] [Choose ]1. Choose (place an X) whether the characteristic applies to the Nervous System or Endocrine System (or both) Characteristic Action is generally brief (lasting milliseconds). Action generally lasts longer (seconds to days). Mediator molecules delivered to target by bloodstream. Action potentials trigger release of mediator molecules at synapse with target. Target cells require specific protein receptor for mediator molecule. Stimulates skeletal muscle contractions. Influence is much broader; will regulate virtually all types of body cells. Controls growth & development and regulates reproductive systems. Maintains internal environments (homeostasis) Nervous Endocrine Mediator molecules include acetylcholine, glutamate, norepinephrine, serotonin Mediator molecules include aldosterone, melatonin, insulin, calcitoninMrs. Jackson, who suffers from seizures, has been stable on a phenytoin dose of 300 mg q.d. (qd or QD) for over a year. However, she has recently been experiencing periods of heartburn. When you ask her more about this, you find there are no red-flag symptoms. She has tried OTC antacids in the past, but did not like them. Instead, she has seen Nexium tablets advertised and wants to know if they would be suitable. Is this an appropriate choice of OTC treatment? Explain in detail and based on scientific reasoning.
