SOLVED

 Question 11 A patient who is hemodynamically stable has been receiving protein replacement therapy for several days. The nurse realizes that which laboratory test would be the best to determine the patient’s current nutritional status? 1. Total lymphocyte count 2. Albumin 3. Transferrin 4. Vitamin assay Question 12 A patient, diagnosed with malnutrition and who has known exposure to Candida was given an intradermal Candida test dose 3 days ago. The site is currently showing no signs of induration. How would the nurse evaluate this finding? 1. There is lack of anergy. 2. There is no current infection with Candida. 3. The immune system has been impaired, possibly by malnutrition. 4. The test should be repeated in 48 hours. Question 13 A patient in the intensive care unit is at risk for developing malnutrition. Indirect calorimetry is planned to estimate the patient’s caloric needs. Which information would the nurse provide to this patient? 1. “You will be taken to a special chamber where you can be isolated.” 2. “You will be required to exercise on a treadmill for this testing.” 3. “You can expect this test to take about 15–20 minutes.” 4. “In order for results to be accurate, I will need to measure your height.” 5. “We will not be able to do this test until you are off the mechanical ventilator.” Question 14 A patient’s respiratory quotient is measured to be 1.1. How would the nurse interpret this information? 1. A vitamin deficiency is present. 2. The patient has the potential to retain carbon dioxide. 3. Malnutrition is present. 4. The patient has fluid overload. 5. The patient is receiving too much carbohydrate. Question 15 The nurse is monitoring a patient’s metabolic status with a thermodilution catheter to determine oxygen saturation of venous blood. How would the nurse report the findings of this test? 1. As oxygen extraction 2. Using the Fick equation 3. As indirect calorimetry 4. As direct calorimetry Question 16 The nurse is going to calculate a patient’s metabolic needs by using the Harris-Benedict equation. Which information should the nurse collect for this calculation? 1. Height in centimeters 2. Weight in kilograms 3. Age in months 4. Body mass index 5. Body temperature Question 17 A patient has a pituitary adenoma that has increased secretion of thyroid-stimulating hormone. Which nutritional effect, if any, will the nurse note in this patient? 1. Metabolism will be increased. 2. The patient’s appetite will be suppressed. 3. No changes will be noted. 4. The patient will crave salt. Question 18 The patient was admitted to the emergency department after being injured in a drive-by shooting. Despite very serious injuries, the patient is awake and alert and cries continuously that “someone tried to kill me.” The nurse tries to calm the patient because of which catecholamine affects? 1. Increased heart rate 2. Increased blood pressure 3. Constriction of coronary vessels 4. Constriction of blood vessels in skeletal muscles 5. Increase in blood glucose Question 19 The nurse is reviewing laboratory results and the dietician’s analysis of a hospitalized patient’s normal home diet. The nurse would plan to support additional amounts of nutrients based on which percentages? 1. Carbohydrates 35% 2. Fat 7% 3. Protein 45% 4. Thiamine 18 ng/mL 5. Magnesium 2.2 mEq/L Question 20 It is necessary to measure a patient’s height, but the patient’s legs are suspended in traction. Which nursing action is indicated? 1. Measure from the patient’s head to the iliac crest and use a standard table to estimate height. 2. Remove the traction weights long enough to quickly measure length of one leg. 3. Measure the patient’s arm span. 4. Estimate the patient’s height from his stated weight.
