CNUR 203 Module 1 fluid, electrolytes and
integumentary Exam Questions With Correct
Answers
Define Hematology - CORRECT ANSWER✔✔-study of blood and blood disorders
| | | | | | | | |
Define homeostasis - CORRECT ANSWER✔✔-state of equilibrium in the internal
| | | | | | | | | |
environment of the body, naturally maintained by adaptive responses that
| | | | | | | | | |
promote healthy survival.
| |
What is the purpose of sodium in the body? - CORRECT ANSWER✔✔-Acid-base
| | | | | | | | | | | |
balance. Attract and hold on to water. Maintain blood pressure. Generate and
| | | | | | | | | | | |
transmit nerve impulses. Muscle contraction
| | | |
What is hypernatremia? - CORRECT ANSWER✔✔-serum sodium levels become
| | | | | | | | |
elevated (exceeds 145 mEq/dL) as a result of H2O loss or sodium gain. Causes
| | | | | | | | | | | | | |
hyperosmolality, which causes the shift of water out of cells, causing cellular
| | | | | | | | | | | |
dehydration.
What are the symptoms of hypernatremia and how does it affected vital signs? -
| | | | | | | | | | | | | |
CORRECT ANSWER✔✔-Symptoms: Thirst, Dry swollen tongue, Weight gain,
| | | | | | | |
Restlessness, Weakness, Seizures, Coma, Edema, lethargy
| | | | |
vital signs: Hypertension (short term to maintain homeostasis), Hypotension
| | | | | | | | |
(severe), tachycardia, fever, and tachypnea
| | | |
, What is hyponatremia? - CORRECT ANSWER✔✔-low serum sodium levels caused
| | | | | | | | | |
by loss of sodium containing fluids, excess water intake or both (serum sodium
| | | | | | | | | | | | |
level less than 135 mEq/L)
| | | |
What are the symptoms of hyponatremia? How does it affect vital signs? -
| | | | | | | | | | | | |
CORRECT ANSWER✔✔-Symptoms: (mild) headache, irritability, difficulty
| | | | | |
concentrating. (severe) confusion, vomiting, seizures, coma.
| | | | |
Vitals: Hypertension, Tachycardia, Rapid pulse, Tremors
| | | | |
What is the difference between hypovolemia and dehydration? - CORRECT
| | | | | | | | | |
ANSWER✔✔-dehydration refers solely to loss of water due to sodium imbalance, | | | | | | | | | | |
whereas hypovolemia refers to pure water loss alone
| | | | | | |
What is the purpose of potassium in the body? - CORRECT ANSWER✔✔-K is
| | | | | | | | | | | | |
critical for transmission and conduction of nerve impulses, maintenance of
| | | | | | | | | |
cardiac rhythms, and skeletal/smooth muscle contraction
| | | | |
What is hyperkalemia? What are some of the causes? - CORRECT ANSWER✔✔-A
| | | | | | | | | | | |
serum potassium level that exceeds 5.1 mEq/L.
| | | | | |
causes: high intake of K, impaired renal excretion, k shift from ICF to ECF, or
| | | | | | | | | | | | | | |
combination of factors. Most common = renal failure. Some medications (ACE
| | | | | | | | | | |
inhibitors)
