5% Dextrose in water (D5W)
HYPOTONIC when infused. Not good for pt with low electrolytes (because it doesn't contain any) and is not going to help low BP, will make it worse.
Ejection Fraction (EF)
How much blood a ventricle can eject with one contraction. Normal range is 55-65%. If below 40%, pt will be put on an ACE inhibitor.
Diet for diabetic pts
50% carbs, 30% fat, and 20% protein (give or take 10%). 45-75g (3-5 units) carbs for meals. Complex carbs are best. Starches such as pasta, rice, potatoes, corn, etc. Low fat, high carb. Encourage fiber to break down carbs.

The nurse is preparing to discharge a patient who has a new prescription for Torsemide. Which of these discharge instructions should be included in the patient's teaching? (Select All That Apply). A.Report weakness to your physician immediately B.Please increase your intake of dairy products C.You will need to increase your intake of fresh fruits and vegetables D.You should take this medication with your evening meal E.This drug may cause heart palpitations which should be reported
A, C, E. Torsemide, a loop diuretic, causes renal excretion of potassium. This may result in weakness and heart palpitations which should be immediately reported to the physician. The patient should also be instructed to eat fresh fruits and vegetables to replenish potassium.
Which of the following best demonstrates a patient's fluid status? A.Hematocrit B.Intake/Output C.Blood Pressure D. Skin Turgor
A. The serum hematocrit and urine specific gravity are both very reliable is determining fluid status because they show a measurement of solvent/solute. I/O, VS, and skin turgor may indicate fluid status but are less reliable and more likely to change because of other variables.
Relationship between Phosphorus and Calcium
ANTAGONISTS. Hyperphosphatemia=hypocalcemia. Hypophosphatemia=hypercalcemia.
BNP
Above 100 could indicate heart failure (HF).
Magnesium and Calcium
Act as sedatives when too high (muscle relaxants). Act as stimulants when too low (twitches and spasms).
Differentiate between atherosclerosis and arteriosclerosis.
Atherosclerosis- accumulation of plaque in the lining of the intimal artery. Arteriosclerosis- hardening of the arteries.
You are caring for a patient with a diagnosis of pancreatitis. The patient was admitted from a homeless shelter and is a vague historian. The patient appears malnourished and on day 3 of the patient's admission total parenteral nutrition (TPN) has been started. Why would you know to start the infusion of TPN slowly? A) Patients receiving TPN are at risk for hypercalcemia if calories are started too rapidly. B) Malnourished patients receiving parenteral nutrition are at risk for hypophosphatemia if calories are started too aggressively. C) Malnourished patients who receive fluids too rapidly are at risk for hypernatremia. D) Patients receiving TPN need a slow initiation of treatment in order to allow digestive enzymes to accumulate.
B
Place the sequence of the development of atherosclerosis in the correct order. A. Fibrous plaque develops. B. Intimal layer of the artery is injured. C. Calcification, thrombosis, ulceration of fibrous lesions. D. Deposit of fatty streak on intimal layer.
B, D, A, C.
A client is receiving monthly doses of chemotherapy for treatment of stage III colon cancer. Which laboratory results should the nurse report to the oncologist before the next dose of chemotherapy is administered? Select all that apply.

B, D, E. Chemotherapy causes bone marrow suppression and risk of infection. A platelet count of 40,000 and a WBC of 2.3 are low. A temperature of 101.2 is high and could indicate an infection. Further assessment and examination should be performed to rule out infection. The BUN, HGB, and specific gravity values are normal.
A 22 year old woman who is 12 weeks pregnant is admitted with intractable (unrelieved) vomiting. Which of the following treatments are priorities in this patient's care? (Select all that apply). A.Reassuring her that everything will be okay B.Reviewing electrolyte levels C.Administering D51/2 Normal Saline D.Encouraging intake of oral fluids E.Administering 0.9% Normal Saline
B, E. Excessive vomiting in this patient depletes potassium and fluids. Assessments would include reviewing electrolyte levels and hydration status. Appropriate interventions would include restoring isotonic fluids intravenously.
The triage nurse is assessing a patient who has come to the emergency room stating that he feels like he is having a heart attack. He is anxious even though EKG readings are normal indicating that he is not having a heart attack. The arterial blood gas findings include pH 7.48, PaO2 110, PaCO2 25, HCO3 24. The nurse would anticipate which initial intervention to correct this problem? A. Administer oxygen through a simple mask. B. Encourage the patient to inhale and exhale slowly into a paper bag. C. Prepare to start normal saline intravenously. D. Anticipate the administration of intravenous sodium bicarbonate.
B. This patient is suffering from hyperventilation resulting in loss of carbon dioxide leading to respiratory alkalosis. To replenish carbon dioxide and decrease the pH, the patient should use a paper bag to rebreathe his own exhaled CO2.
Parkinson's symptoms
Bradykinesia, resting tremor, small handwriting, poor speech, poor posture, rigid muscles, stoic expression (mask-like), shuffling gait, depression, dysphagia, decreased blinking. Rarely occurs in black population.
You are called to your patient's room by a family member who voices concern about the patient's status. On assessment, you find the patient tachypenic, lethargic, weak, and exhibiting a diminished cognitive ability. You also find 3+ pitting edema. What electrolyte imbalance is the most plausible cause of this patient's signs and symptoms? A) Hypocalcemia B) Hyponatremia C) Hyperchloremia D) Hypophosphatemia
C. The signs and symptoms of hyperchloremia are the same as those of metabolic acidosis: hypervolemia and hypernatremia. Tachypnea; weakness; lethargy; deep, rapid respirations; diminished cognitive ability; and hypertension occur. If untreated, hyperchloremia can lead to a decrease in cardiac output, dysrhythmias, and coma.
Chovstek's sign
C=Cheek Sign of hypocalcemia or hypomagnesemia; abnormal functioning of the facial nerve causes a twitch on the same side of the face
Which of the following vital signs would alert the nurse to the development of hypermagnesmia? A.T-99.7 HR-144 RR-20 B/P-167/87 B.T-99.0 HR-110 RR-18 B/P-98/52 C.T-98.6 HR-88 RR-16 B/P-128/70 D.T-97.8 HR-68 RR-12 B/P-104/62
D. Excess magnesium results in an overall sedative effect, lowering the respiratory rate, heart rate and blood pressure.

skin traction
pulling mechanisms are attached to skin. This is a COMFORT MEASURE to reduce muscle spasms. Don't need to monitor for infection.
Upper GI Bleed
tarry/dark stool (melena), bright red or dark coffee ground vomitus appearance, dizziness or fainting. Look at H&H to evaluate extent of loss. VS: low BP, high HR, high RR, pale, low urine output.
Uses for sodium bicarbonate IV
to treat acidosis, prevent acidosis (tumor lysis syndrome), or if pt has kidney dysfunction. Giving this IV for anything besides these problems will result is alkalosis.
