The metabolic system is regulated by which organ?
The respiratory system is regulated by which organ?
Metabolic system is regulated by the kidneys
Respiratory is regulated by the lungs
What is the relationship between pH and Potassium K?
Does acidosis cause hyperkalemia or hypokalemia?
K+ regulates the pH of intracellular/extracellular fluid.
When K+ goes into a blood cell, the patient experiences acidosis and hyperkalemia.
When K+ leaves the blood cell, the patient experiences hypokalemia and alkalosis
What are the normal ranges for:
K
Ca
Mg
Na
K: 3.5-5
Ca: 8.5-11
Mg: 1.3-2.1
Na: 135-145
What is the definition of third spacing?
Third spacing is fluid that has entered the space between the cells (Intercellular fluid) and becomes trapped
When fluid has leaked into the abdominal cavity, this becomes an issue known as what?
Ascites
What does CVP mean, what does it refer to and what is the normal CVP range?
CVP stands for Central Veinous Pressure and refers to the amount of blood that returns into the right atrium
Normal range is 2-8mmHG
What does a high CVP indicate?
High CVP can indicate right ventricular failure or fluid volume overload.
What does a low CVP indicate?
Low CVP indicates Hypovolemia (low blood volume)
What are some physical examples fluid volume overload effects on the body?
Edema
High blood pressure
High CVP
Crackles in the lungs
Weight gain
Polyurea
Jugular Veinous Distention
How do you treat Fluid Volume Overload?
Diuretics and decreases intake of fluids are the main therapies.
If fluid volume excess leads to pleural effusion, what can be done to solve the issue?
An abdominal paracentesis or a thoracentesis
What is the primary cause/spread of HIV infections?
The Retrovirus that is transmitted via bodily fluids attaches to host cells and kills host T-cells
What are the primary symptoms of HIV infection for the first 2-4 weeks?
Flu-like symptoms, so fever, chills, fatigue
How long can HIV lay dormant before showing signs of infection again?
8-10 years.
After HIV returns from its dormancy, what are the symptoms you would see?
Fever, frequent night sweats, fatigue, and AMS (altered Mental Status)
What is the best prevention method for HIV?
The prophylactic method of Anti-Retroviral drug therapy
What are the 3 types of drugs used for the therapy of HIV?
-Reverse Transcriptase Inhibitors (NRTI’s and NNRTI’s)
-Protease inhibitors
-Integrase inhibitors
What lab levels are important to maintain for the successful survival and treatment of HIV?
T-cell and CD4 count between 200-500 at least, but ABOVE 200 at all times.
If your T-cell count falls below <200 while you are infected with HIV, what is your greatest risk?
Opportunistic infections
A complication of HIV is Kapasi Sarcoma. How would you describe Kapasi Sarcoma?
Purple-brown lesions that are cancerous and can be fluid filled and painful.
Renal Carcinoma, Dementia, and Candida Pneumo Cystitis are all complications of what disease?
HIV
What is the primary cause of TB?
Mycobacterium Tuberculosis
How is TB spread?
Through infected air droplets that are airborne and stay in the air
What are the most basic symptoms of TB?
dry productive cough
fatigue
night sweats
weight loss
dyspnea
crackles
