NUR2063 Essentials of Pathophysiology Final Exam Study Guide What is the difference between a sign and a symptom?(Ans- Sign - Objective (Erythema, Edema, lesion) Symptom - Subjective (Headache, sore, tired) Na – Sodium (Ans- 136-144 mEq Hyponatremia - anorexia, gastrointestinal upset, poor skin turgor, dry mucous membranes, blood pressure changes, pulse changes, edema, headache, lethargy, confusion, diminished deep tendon reflexes, muscle weakness, seizures, and coma | Hypernatremia - increased temperature, warm and flushed skin, dry and sticky mucous membranes, dysphagia, increased thirst, irritability, agitation, weakness, headache, seizures K - Potassium (Ans- o 3.7-5.2 mEq | Hypokalemia - muscle weakness, paresthesia, hyporeflexia, leg cramps, weak and irregular pulse, hypotension, dysrhythmias, electrocardiogram changes, decreased bowel sounds, abdominal distension, constipation, ileus, and cardiac arrest| 1 / 3
Hyperkalemia - paresthesia, muscle weakness, flaccid paralysis, bradycardia, dysrhythmias, electrocardiogram changes, cardiac arrest, respiratory depression, abdominal cramping, nausea, and diarrhea Mg - Magnesium (Ans- .8-2.5 mEq | Hypermagnesemia - Same as hypercalcemia | Hypomagnesemia
- same as hypocalcemia
Ca – Calcium (Ans- 4 - 5 mEq | Hypercalcemia - dysrhythmias, electrocardiogram changes, personality changes, confusion, decreased memory, headache, lethargy, stupor, coma, muscle weakness, decreased deep tendon reflexes, anorexia, nausea, vomiting, constipation, abdominal pain, pancreatitis, renal calculi, polyuria, and dehydration | Hypocalcemia - dysrhythmias, electrocardiogram changes, increased bleeding tendencies, anxiety, confusion, depression, irritability, fatigue, lethargy, paresthesia, increased deep tendon reflexes, tremors, muscle spasms, seizures, laryngeal spasms, increased bowel sounds, abdominal cramping, and positive Trousseau's and Chvostek's signs P – Phosphorus (Ans- .5 - 4.5 mg | Hyperphosphatemia - dysrhythmias, electrocardiogram changes, increased bleeding tendencies, anxiety, confusion, depression, irritability, fatigue, lethargy, 2 / 3
paresthesia, increased deep tendon reflexes, tremors, muscle spasms, seizures, laryngeal spasms, increased bowel sounds, abdominal cramping, and positive Trousseau's and Chvostek's signs Hypophosphatemia - dysrhythmias, electrocardiogram changes, personality changes, confusion, decreased memory, headache, lethargy, stupor, coma, muscle weakness, decreased deep tendon reflexes, anorexia, nausea, vomiting, Function of ribosomes (Ans- Synthesizes proteins · Hypervolemia (Ans- Fluid volume excess in intravascular space · Hypovolemia (Ans- Fluid volume deficit in intravascular space · Homeostasis (Ans- State of balance - reached by positive and negative feedback - self regulated · How does a vaccine provide immunity?(Ans- Active immunity - antigen exposure · Active immunity (Ans- Vaccine, or having the virus - Body builds immunity through exposure · Passive immunity
