A nurse in the emergency department is assessing a young adult client who was administered a hypotonic IV fluid bolus for rehydration after collapsing at an athletic event. Which of the following findings indicates the client is experiencing water intoxication?
Hypernatremia
Weak pulses
Muscle weakness
Exaggerated reflexes
The Correct Answer is C
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 B
Explanation
Choice A reason: Administering the feeding by gravity drip is not an appropriate action for a client who has a small-bore jejunostomy tube and is receiving a high-viscosity formula. Gravity drip can cause overfeeding, aspiration, and abdominal distension. The nurse should use an infusion pump to regulate the flow rate and volume of the feeding.
Choice B reason: Flushing the tubing with 10 mL water every 6 hr is an appropriate action for a client who has a small-bore jejunostomy tube and is receiving a high-viscosity formula. Flushing the tubing prevents clogging, maintains patency, and hydrates the client. The nurse should also flush the tubing before and after medication administration, and whenever the feeding is interrupted or discontinued.
Choice C reason: Replacing the bag and tubing every 24 hr is not an appropriate action for a client who has a small-bore jejunostomy tube and is receiving a high-viscosity formula. Replacing the bag and tubing every 24 hr does not prevent clogging, and may increase the risk of infection and contamination. The nurse should replace the bag and tubing every 48 hr, or as per facility policy.
Choice D reason: Heating the formula prior to infusion is not an appropriate action for a client who has a small-bore jejunostomy tube and is receiving a high-viscosity formula. Heating the formula can alter its composition, reduce its nutritional value, and increase the risk of bacterial growth. The nurse should use room-temperature formula and store it in a refrigerator when not in use.
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.
