A nurse on a medical surgical unit is caring for a client who has a small bowel obstruction and is receiving parenteral nutrition through a central venous catheter. Which of the following actions should the nurse plan to take? (Select all that apply)
Observe for dyspnea.
Infuse parenteral nutrition by gravity.
Administer parenteral nutrition solution within 30 min after removing from the refrigerator.
Change parenteral nutrition bag and infusion tubing every 72 hr.
Begin infusion of parenteral nutrition once central venous catheter position is confirmed by radiology.
Correct Answer : A,C,E
Choice A reason: Dyspnea is a sign of pulmonary edema, which can occur as a complication of parenteral nutrition due to fluid overload or allergic reaction¹². The nurse should monitor the client's respiratory status and oxygen saturation and report any signs of respiratory distress.
Choice B reason: Parenteral nutrition should not be infused by gravity, as this can cause fluctuations in the infusion rate and lead to hyperglycemia or hypoglycemia¹³. The nurse should use an infusion pump to deliver parenteral nutrition at a constant and controlled rate.
Choice C reason: Parenteral nutrition solution should be administered within 30 min after removing from the refrigerator, as prolonged exposure to room temperature can increase the risk of bacterial contamination and infection¹⁴. The nurse should check the expiration date and inspect the solution for any discoloration, cloudiness, or particulate matter before administration.
Choice D reason: Parenteral nutrition bag and infusion tubing should be changed every 24 hr, not every 72 hr, to prevent the growth of microorganisms and reduce the risk of infection¹⁵. The nurse should use aseptic technique when changing the bag and tubing and follow the facility's protocol for dressing changes and catheter care.
Choice E reason: Parenteral nutrition should be started only after the central venous catheter position is confirmed by radiology, as incorrect placement can cause serious complications such as pneumothorax, hemothorax, or cardiac tamponade¹⁶. The nurse should obtain a chest x-ray and wait for the provider's confirmation before initiating parenteral nutrition.

Correct Answer is C
Explanation
Choice A reason: Hypernatremia is not a sign of water intoxication, but rather the opposite condition. Hypernatremia means high sodium levels in the blood, which can occur when the body loses more water than sodium, such as in dehydration, diabetes insipidus, or excessive salt intake. Water intoxication causes hyponatremia, which means low sodium levels in the blood, due to excessive water intake or retention.
Choice B reason: Weak pulses are not a specific sign of water intoxication, but rather a general sign of poor perfusion or circulation. Weak pulses can have many causes, such as hypotension, shock, heart failure, or peripheral vascular disease. Water intoxication can cause hypotension, but it can also cause hypertension, depending on the volume status of the client.
Choice C reason: Muscle weakness is a sign of water intoxication, as it reflects the effect of low sodium levels on the neuromuscular system. Sodium is essential for nerve and muscle function, as it helps generate electrical impulses and contractions. When sodium levels drop too low, the nerves and muscles become less responsive and weaker. Other signs of water intoxication affecting the nervous system include confusion, headache, seizures, and coma.
Choice D reason: Exaggerated reflexes are not a sign of water intoxication, but rather a sign of hyperreflexia, which is a condition of overactive reflexes. Hyperreflexia can have many causes, such as spinal cord injury, stroke, multiple sclerosis, or electrolyte imbalance. Water intoxication can cause electrolyte imbalance, but it usually leads to hyporeflexia, which is a condition of reduced or absent reflexes.
Correct Answer is A
Explanation
Choice A reason: Confusion and weakness are signs of dehydration and electrolyte imbalance, which can result from vomiting and diarrhea. These are serious complications that can affect the client's mental status, blood pressure, heart rate, and kidney function. The nurse should report these findings to the provider and monitor the client's vital signs and fluid status.
Choice B reason: Dry oral mucosa and furrowed tongue are also signs of dehydration, but they are less severe than confusion and weakness. The nurse should report these findings to the provider as well, but they are not the most urgent ones.
Choice C reason: A temperature of 37.4° C (99.3° F) is slightly elevated, but not indicative of a fever or infection. The nurse should document this finding, but it does not require immediate follow-up.
Choice D reason: A blood pressure of 90/58 mm Hg is low, but not hypotensive. The nurse should document this finding, but it does not require immediate follow-up.
