Question 1: The force exerted by water in the blood stream

Answer:

hydrostatic pressure

Question 2: Are you acidic or basic with high concentration of Hydrogen ions?

Answer:

Acidic which is a low pH

Question 3: These are S/sx of what electrolyte deficiency?

Headache, confusion, vomiting, muscle cramps, and lethargy

Answer:

Hyponatremia.... common with hypervolemia Question 4: An ICU patient's arterial blood gas results show low pH and low CO2 levels. The patient's respiratory rate is increased.What is the name of this condition?1Respiratory alkalosis 2Metabolic alkalosis

• Respiratory acidosis

4Metabolic acidosis

Answer:

4-Since the pH is low, and the pH and CO2 are trending in the same direction, the condition is metabolic acidosis. The low CO2 indicates that CO2 is not causing the acidosis. The increased respiratory rate lowers blood CO2 in an attempt to compensate for the metabolic acidosis.Question 5: Your patient has experienced significant blood loss due to an injury incurred in a car accident.Which physiological response is to be expected?1Vasodilation will help to reduce blood pressure.2ADH will stimulate the kidneys to reabsorb more water.3The adrenal gland will stop releasing aldosterone.4The RAAS will be inactivated.

Answer:

2-ADH is produced in response to hypovolemia and stimulates the patient's kidney to reabsorb water.This reabsorption will help to compensate for the blood loss.

Question 6: These are S/sx of what electrolyte deficiency?

Dry mouth, irritability, hypertension, weight gain, oliguria, and dry skin

Answer:

Hypernatremia Question 7: A patient with a viral illness and severe vomiting has an elevated CO2 level and a blood pH of 7.53. She is breathing slowly.What condition does the patient have?Respiratory alkalosis.Metabolic alkalosis Respiratory acidosis Metabolic acidosis

Answer:

Metabolic Alkalosis-The patient's pH and CO2 level are both elevating (moving in the same direction).This indicates metabolic alkalosis. The CO2 level is high because her respiratory system is attempting to compensate for the high pH by exhaling less and retaining more CO2

Question 8: Are you acidic or basic with a lower concentration of of Hydrogen ions?

Answer:

Basic which is a High pH

Question 9: What happens in a dehydrated patient?

ADH levels increase and the RAAS is inactivated.ADH levels decrease and the RAAS is activated.ADH levels decrease and the RAAS is inactivated.ADH levels increase and the RAAS is activated.

Answer:

ADH levels increase and the RAAS is activated-Osmoreceptors will stimulate the secretion of ADH from the posterior pituitary. In addition, low circulation stimulates the kidney to make renin, and the RAAS will increase blood volume and blood pressure by promoting the reabsorption of water and sodium in the kidney and through vasoconstriction.

Question 10: Which explains how ACE inhibitors work?

• The decrease in the production of angiotensin II constricts blood vessels. This lowers blood

pressure.

• The decrease in the production of angiotensin II keeps blood vessels more dilated. This

lowers blood pressure.3The decrease in the production of angiotensin II constricts blood vessels. This raises blood pressure.

Answer:

Normally, the RAAS is activated in response to low blood pressure, and its actions help to raise blood pressure. As part of this response, angiotensin II is produced and causes vasoconstriction.Vasoconstriction increases blood pressure. Sometimes individuals with high blood pressure are prescribed ACE inhibitors. The decrease in the production of angiotensin II keeps blood vessels more dilated. This lowers blood pressure.

Question 11: HCo3-

Answer:

22-26 Meq/L

Question 12: The force exerted by albumin in the blood stream

Answer:

oncotic pressure

Question 13: What is the natural diauretic of the body? It is from excretion of large amounts of NA and water by the kidneys?

Answer:

Natruiesis Question 14: The pressure exerted by electrolytes in the blood stream that forces that pulls water into the blood stream from the ISF/ICF

Answer:

osmotic pressure Question 15: what type of IV solution will cause the cells to shrink by adding solutes to the blood stream?isotonic hypertonic hypotonic

Answer:

Hypertonic.... common to give in cerebral edema Question 16: what enables her body to maintain homeostasis despite her increased activity?Choose 3

• Diane's sports drink helped to replace sodium and water lost due to sweating.
• Diane's body produces more angiotensin II, allowing her body to constrict blood vessels and

increase her blood pressure.

• Diane's kidney reabsorbs more water and sodium in response to ADH and aldosterone.
• Extracellular fluid shifts into intracellular fluid, expanding cells and stimulating the thirst

center in the hypothalamus

Answer:

1,2,3 Question 17: Respirations slow down to increase C02 retention.... there is lack of hydrogen (blood more basic)

Answer:

Metabolic Alkalosis.... treat by resolve the acid/base balance... like give nausea medication if vomiting.

Question 18: PH is from the concentration of what?

Answer:

Hydrogen molecules
