Chapter 14 Nutrition and Fluid Balance Workbook Answers Questions
Question 1 of 5
The critical care nurse is responsible for monitoring the patient receiving continuous renal replacement therapy (CRRT). In doing so, the nurse should
Correct Answer: B
Rationale: The correct answer is B: assess the hemofilter every 6 hours for clotting. This is crucial in CRRT as clotting can lead to decreased efficacy or even system failure. By checking the hemofilter regularly, the nurse can detect clot formation early and prevent complications. Assessing the blood tubing for warmth (A) is not a reliable indicator of clotting or malfunction. Covering dialysis lines to protect from light (C) is not necessary for CRRT monitoring. Using clean technique during vascular access dressing changes (D) is important for infection prevention but not directly related to hemofilter clotting in CRRT.
Question 2 of 5
Which type of transeellular fluid is associated with the intestines?
Correct Answer: A
Rationale: The correct answer is A: peritoneal fluid. The peritoneal fluid is the transcellular fluid associated with the intestines. It is found within the peritoneal cavity, which surrounds the abdominal organs, including the intestines. Peritoneal fluid helps lubricate the abdominal organs and allows them to move smoothly during digestion. Pericardial fluid (B) is found in the pericardial sac surrounding the heart, intrapleural fluid (C) is in the pleural cavity surrounding the lungs, and synovial fluid (D) is found in joint cavities. These fluids serve different purposes and are not directly associated with the intestines.
Question 3 of 5
Which of these statements does NOT describe normal blood pH?
Correct Answer: D
Rationale: The correct answer is D because normal blood pH is slightly basic, not acidic. Blood pH range is narrow (7.35-7.45) for optimal physiological function. A is incorrect because blood pH is slightly basic, not acidic. B is incorrect because the normal range of blood pH is indeed narrow. C is incorrect as it accurately describes the normal range of blood pH. Thus, D is the only statement that does not describe normal blood pH.
Question 4 of 5
A 34-year-old male client has diagnoses of liver failure, ascites, and hepatic encephalopathy secondary to alcohol abuse. The client's family is questioning the care team as to why his abdomen is so large even though he is undernourished and emaciated. Which of the following statements most accurately underlies the explanation that a member of the care team would provide the family?
Correct Answer: C
Rationale: The correct answer is C: Normally small transcellular fluid compartment, or third space, is becoming enlarged. In liver failure with ascites, there is an abnormal accumulation of fluid in the peritoneal cavity due to low oncotic pressure from decreased albumin production by the liver. This results in an enlarged transcellular fluid compartment, known as the "third space," leading to the distended abdomen. Options A, B, and D are incorrect because they do not accurately explain the specific fluid compartment enlargement seen in ascites related to liver failure. Option A refers to interstitial fluid, not the transcellular compartment. Option B incorrectly mentions the intracellular fluid compartment, which is not the primary issue in ascites. Option D incorrectly refers to plasma accumulating in the peritoneal cavity, which is not the mechanism behind the abdominal distension in this case.
Question 5 of 5
You are volunteering in the medical tent of a road race on a hot, humid day. A runner who has collapsed on the road is brought in with the following symptoms: sunken eyes, a body temperature of 100F, and a complaint of dizziness while sitting to have his blood pressure taken (which subsides upon his lying down). These are signs of a fluid volume deficit. Which of the following treatments should be carried out first?
Correct Answer: D
Rationale: The correct answer is D: Give him an electrolyte solution by mouth. This is the first step because the runner is showing signs of dehydration, indicated by sunken eyes and dizziness. Providing electrolyte solution by mouth helps replenish lost fluids and essential electrolytes. Option A, offering water by mouth, may not be enough to address the electrolyte imbalance. Option B, cooling the body, is not the priority when the primary concern is fluid deficit. Option C, giving a transfusion of FFP, is unnecessary and not indicated for fluid volume deficit. Administering an electrolyte solution addresses the immediate need for rehydration and helps restore the body's electrolyte balance efficiently.
