A client receives a prescription for 3 liters of lactated Ringer's IV to infuse over 24 hours.
How many mL/hr should the nurse program the infusion pump? (Enter numerical value only)
The Correct Answer is ["125"]
To calculate the infusion rate in mL/hr, you would convert the total volume of lactated Ringer's IV from liters to milliliters (since there are 1,000 milliliters in a liter, 3 liters is equivalent to 3,000 milliliters) and then divide by the total number of hours over which the infusion is to be administered. In this case, 3,000 mL divided by 24 hours results in an infusion rate of 125 mL/hr.

Correct Answer is A
Explanation
A. Palpitations and shortness of breath are symptoms of thyrotoxicosis, indicating excessive thyroid hormone levels, which could result from an overdose of levothyroxine sodium.
B. Bradycardia and constipation are more indicative of hypothyroidism, which would suggest the need for an increase in levothyroxine dosage rather than a decrease.
C. Muscle cramping and dry, flushed skin are symptoms of hypothyroidism, which would suggest inadequate thyroid hormone replacement rather than excess.
D. Lethargy and lack of appetite are also symptoms of hypothyroidism, not hyperthyroidism, which would not typically result from an overdose of levothyroxine.
Correct Answer is B
Explanation
A. Internal bleeding may present with symptoms such as hypotension, tachycardia, and signs of blood loss, but it typically does not cause pitting edema or jugular venous distention.
B. Right-sided heart failure can cause systemic venous congestion, leading to pitting edema of the lower extremities and jugular venous distention due to increased central venous pressure.
C. Cardiac tamponade presents with Beck's triad (hypotension, distended neck veins, muffled heart sounds) and is typically more acute in onset compared to the gradual development of symptoms seen in right-sided heart failure.
D. Left ventricular dysfunction primarily causes symptoms of pulmonary congestion, such as dyspnea, orthopnea, and crackles, rather than pitting edema and jugular venous distention.
