Patients with adequate peripheral venous access
Answer: B
Explanation: A peripherally inserted central catheter (PICC) is commonly used for long-term nutrition support in patients with severe malabsorption. It provides a more secure and stable access point for delivering parenteral nutrition compared to peripheral venous access. Short-term nutrition support can be achieved through peripheral venous access, and patients with a history of central line-associated bloodstream infections (CLABSIs) may require alternative access options.
A patient with a history of diabetes and renal failure is receiving nutritional support. Which electrolyte imbalance should be monitored closely in this scenario?
Hypocalcemia
Hyperkalemia
Hyponatremia
Hypomagnesemia
Answer: B
Explanation: Patients with renal failure are at high risk for hyperkalemia due to impaired potassium excretion, particularly when receiving nutrition support that may include potassium.
Which of the following conditions is associated with increased protein needs?
Hypothyroidism
Type 2 diabetes mellitus
Chronic kidney disease
Iron deficiency anemia
Answer: C
Explanation: Chronic kidney disease is associated with increased protein needs due to the loss of protein through urine and increased protein breakdown. Adequate protein intake is essential to prevent malnutrition and maintain muscle mass in individuals with kidney disease.
A 75-year-old male with end-stage renal disease is on hemodialysis and presents with symptoms of malnutrition. What is the recommended protein intake for this patient to meet his nutritional needs while preventing complications?
0.6 g protein/kg/day.
2.0 g protein/kg/day.
1.5 g protein/kg/day.
1.2 g protein/kg/day.
Answer: D
Explanation: For patients with end-stage renal disease on hemodialysis, a protein intake of 1.2 g protein/kg/day is recommended to compensate for protein losses during dialysis while maintaining nutritional status.
During a nutritional assessment, a patient reports significant financial difficulties affecting their access to food and healthcare. Which of the following factors should be prioritized in the nutrition support plan to improve the patient's overall well-being?
Initiating oral nutritional supplements
Implementing a high-protein diet
Focusing solely on macronutrient intake
Referring the patient to a social worker
Answer: D
Explanation: Addressing socio-economic factors is essential for improving access to food and healthcare. A referral to a social worker can help the patient navigate resources available to them.
Which of the following is a potential complication of untreated hypothyroidism?
Depression
Weight loss
Hyperactivity
Heat intolerance
Answer: A
Explanation: Depression is a potential complication of untreated hypothyroidism. Hypothyroidism is a condition characterized by an underactive thyroid gland, which leads to a decrease in the production of thyroid hormones. Thyroid hormones play a role in regulating mood, and low levels of these hormones can contribute to symptoms of depression. Hyperactivity (option A) is more commonly associated with hyperthyroidism (overactive thyroid). Weight loss (option B) is not typically seen in hypothyroidism; instead, weight gain is a common symptom. Heat intolerance (option D) is associated with hyperthyroidism. Therefore, option C is the correct answer.
A patient on parenteral nutrition develops new-onset hypertriglyceridemia. Which of the following changes would be most appropriate to manage this complication while continuing nutritional support?
Increase the rate of dextrose infusion
Reduce the lipid infusion rate
Switch to a higher-calorie formula
Initiate insulin therapy
Answer: B
Explanation: Reducing the lipid infusion rate directly addresses hypertriglyceridemia while allowing the continuation of nutritional support through other macronutrients.
In a critically ill patient requiring nutrition support therapy, what is the most appropriate initial approach to determining the feeding route?
Initiate parenteral nutrition to ensure nutrient delivery
Use enteral nutrition exclusively, regardless of the patient's condition
Begin with oral nutrition to maintain normalcy

Which of the following is a common symptom of vitamin B12 deficiency?
Fatigue
Night blindness
Rickets
Scurvy
Answer: A
Explanation: A common symptom of vitamin B12 deficiency is fatigue. Vitamin B12 plays a crucial role in the production of red blood cells and the maintenance of nerve cells. When levels of vitamin B12 are low, it can lead to a condition called pernicious anemia, which is characterized by fatigue, weakness, and shortness of breath. Night blindness is associated with vitamin A deficiency, rickets is associated with vitamin D deficiency, and scurvy is associated with vitamin C deficiency. Therefore, option A is the correct answer.
A patient in the ICU has been on enteral nutrition for three days but is not meeting their caloric goals due to gastrointestinal intolerance. Their current prescription is 1500 kcal/day. What would be the most effective strategy to optimize their nutrition support therapy?
Switch to total parenteral nutrition (TPN)
Increase the caloric density of the enteral formula
Administer medications to enhance gastric motility
Reduce the enteral feeding rate
Answer: B
Explanation: Increasing the caloric density allows the patient to meet nutritional requirements without increasing the volume, which can help reduce gastrointestinal intolerance.
A patient on long-term parenteral nutrition has developed metabolic bone disease. Which modification should be made to their nutrition support therapy to address this complication?
Limit phosphorus intake to prevent further bone loss
Increase the calcium and vitamin D content in their parenteral solution
Switch to a higher-calorie parenteral formula
Reduce the rate of infusion to enhance tolerance
Answer: B
Explanation: Increasing calcium and vitamin D in the parenteral solution is essential to help mitigate the effects of metabolic bone disease and promote bone health.
In the context of nutrition support therapy, which of the following represents a violation of ethical principles when making decisions about patient care?
Utilizing a standardized protocol for all patients
Failing to consider the patient's cultural beliefs in treatment decisions
Collaborating with the healthcare team to develop a care plan
