TPN questions and answers, 100% verified. Questions and answers. 2022/2023. A nurse is reviewing the medical record for a client with a nursing diagnosis of Altered nutrition: Less than body requ... irements. Which assessment data is the best indicator for continued need of additional nutritional support? A Intake and output B Calorie count C Serum electrolytes D Trace element levels - ✔✔B The best indicator of whether a client is taking in adequate oral nourishment following TPN is a calorie count. This gives an idea of the total calories consumed and the distribution of the client's diet in terms of protein, fat, and carbohydrate. Intake and output is useful as a measure of fluid balance, and the laboratory studies previously identified give an indication of electrolyte balance. A physician orders parenteral proteins for a client who is emaciated. A nurse orders the proteins from the pharmacy knowing that parenteral proteins are supplied as: A synthetic crystalline amino acids. B casein amino acids. C immunoglobulins. D albumin. - ✔✔A Protein is a body-building nutrient that promotes tissue growth, repair, and the replacement of body cells. Parenteral proteins are elemental, providing a synthetic crystalline amino acid that does not cause an antigenic reaction. A physician orders a total nutrient admixture (TNA) solution for a client diagnosed with severe anorexia nervosa. A nurse administers the solution knowing that TNA consists of a combination of: A platelets, plasma, and white blood cells B fats, carbohydrates, and proteins. C fats, electrolytes, and trace elements D carbohydrates, proteins, and heparin. - ✔✔B TNA are systems that hold combinations of dextrose, amino acids, and fat emulsions in one container. It is also referred to as all-in-one or three-in-one. A nurse is instructed to add heparin to a client's TPN per a physician's order. What is the purpose of adding heparin to a TPN solution? A To enhance blood glucose levels B To thin the TPN solution so that it easily infuses C To decrease the incidence of subclavian vein thrombosis D To prevent gastric ulcers - ✔✔C Heparin doses of 100 to 300 units/L have been ordered to decrease the incidence of subclavian vein thrombosis. A clinical nurse specialist is conducting an in-service for critical-care nurses regarding the administration of cyclic TPN. Which key point should be included in the in-service? A It is indicated for clients receiving continuous, stabilized TPN. B It is indicated for short-term parenteral nutrition. C It must be escalated to maintain rate. D The dose must be tapered to avoid abrupt changes in glucose levels. - ✔✔A Cyclic TPN is used for long-term stabilized clients. Cyclic TPN is not routinely used for short-term therapy, and after clients receive cyclic TPN, there is no need to escalate or taper doses, because the glucose response has been stabilized. A nurse is caring for a critically ill client who has been admitted to an intensive care unit. The nurse monitors the client's nutritional status. During times of stress, which element of metabolism is radically altered? A Fats B Proteins C Carbohydrates D Vitamin C - ✔✔C The major purpose of carbohydrates is to provide energy. During the critical phase of illness or injury, carbohydrate metabolism is radically altered; thus, hyperglycemia is a hallmark of stress. A nurse is caring for a client receiving TPN. In addition to multiple vitamins, which medication might be anticipated that the nurse administer intramuscularly on a weekly basis? A Heparin 1000 units B Vitamin K 5 mg C Zinc 2.5 mg D Biotin 60 mg - ✔✔B Heparin, zinc, and biotin can be added to the TPN solution. Vitamin K cannot be administered intravenously, so it must be given intramuscularly. A client has a triple-lumen tunneled catheter and is receiving PN with daily infusions of lipids, as well as several other I.V. medications. How should a nurse infuse the lipids? [Show More]
