A nurse is caring for a client who is receiving IV fluid therapy. For which of the following findings should the nurse monitor as an adverse effect of the IV fluid therapy?
Bradypnea
Distended neck veins
Weight loss
Bradycardia
The Correct Answer is B
A. Bradypnea. Slow respiratory rate is not a typical sign of fluid overload. In fact, fluid volume excess may lead to tachypnea or dyspnea as fluid accumulates in the lungs and impairs gas exchange.
B. Distended neck veins. Jugular vein distention is a classic sign of fluid volume overload. It reflects increased central venous pressure and is commonly seen in clients receiving excessive IV fluids or those with heart failure.
C. Weight loss. IV fluid therapy is intended to increase intravascular volume, and adverse effects are usually related to fluid retention, not loss. Weight gain, not weight loss, would indicate fluid overload.
D. Bradycardia. An increased, not decreased, heart rate (tachycardia) is typically seen with fluid volume excess or in response to fluid shifts. Bradycardia is not a common adverse effect of IV fluid therapy.

Correct Answer is A
Explanation
A. Measure the tubing from the nose to the distal port. Proper placement of an NG tube requires measuring from the tip of the nose to the earlobe, then to the xiphoid process. This ensures the tube reaches the stomach without curling or entering the airway.
B. Position the child at a 10 to 20 angle after feeding. A head elevation of at least 30 to 45 degrees is necessary during and after NG feedings to reduce the risk of aspiration. A 10 to 20 degree angle is too low and unsafe for post-feeding positioning.
C. Complete the feeding in 5 min. NG feedings should be given slowly over 20 to 30 minutes to prevent gastrointestinal discomfort, cramping, or vomiting. A 5-minute infusion is too rapid and may overwhelm the child’s digestive capacity.
D. Warm the formula in the microwave. Microwaving formula can lead to uneven heating and hot spots, which pose a burn risk to the child. Formula should be warmed by placing the container in warm water and testing the temperature before administration.
Correct Answer is A
Explanation
A. Respiratory rate 10/min. This is the priority finding because it suggests respiratory depression, a serious side effect of magnesium sulfate therapy. Magnesium acts as a CNS depressant, and a respiratory rate below 12/min is a potential sign of magnesium toxicity, which can lead to respiratory arrest if not promptly addressed.
B. 2+ deep-tendon reflexes. This indicates normal neuromuscular function and is actually a reassuring finding in a client receiving magnesium sulfate. Reflexes are typically monitored to detect early signs of toxicity, and a 2+ rating means the dose is likely therapeutic.
C. 3+ pedal edema. While significant, pedal edema is a common feature of preeclampsia and not directly related to magnesium sulfate toxicity. It should be monitored but does not require immediate action compared to respiratory compromise.
D. Urinary output 35 mL/hr. This is slightly above the minimum acceptable output of 30 mL/hr, indicating the kidneys are excreting adequately. While magnesium is excreted renally and output must be monitored, this value does not indicate an acute risk.
