Answer: 3
Rational: A fluid volume excess is also known as overhydration or fluid overload and occurs when fluid intake or fluid retention exceeds the fluid needs of the body. Assessment findings associated with fluid colume excess include cough, dyspnea, crackles, tachypnea, tachycardia, elevated blood pressure, bounding pulse, elevated CVP, weight gain, edema, neck and hand vein distention, altered level of consciousness, and decreased hematocrit. Options 1, 2, and 4 identify signs noted in fluid volume deficit.
Answer: 1
Rational: The normal serum calcium level is 8.6 - 10.2. A serum calcium level lower than 8.6 indicates hypocalcemia. Signs of hypocalcemia include paresthesias followed by numbness, hyperactive deep tendon reflexes and a positive Trouseau's or Chvosteck's sign. Additional signs of hypocalcemia include increased neuromuscular excitability, muscle cramps, twitching, tetany, seizures, irritability, and anxiety. Gastrointestinal symptoms include increased gastric motility, hyperactive bowel sounds, abdominal cramping, and diarrhea.
Answer: 4
Rational: A fluid volume deficit occurs when the fluid intake is not sufficient to meet the fluid needs of the body. Assessment findings in a client with a fluid volume deficit include increased respirations and heart rate, decreased CVP, weigh loss, poor skin turgor, dry mucous membranes, decreased urine volume, increased specific gravity of the urine, increased hematocrit, and altered level of consciousness. The normal CVP is between 4 and 11 cm H2O. A client with dehydration (fluid volume deficit) has a low CVP. The assessment findings in options 1, 2, and 3 are seen in a client with fluid volume excess.
Answer: 2, 3, 5, & 6
Rational: The normal potassium level is 3.5-5. Common food sources of potassium include avocado, bananas, cantaloupe, carrots, fish, mushrooms, oranges, potatoes, pork, beef, veal, raisins, spinach, strawberries, and tomatoes. Peas and cauliflower are high in magnesium.
