A nurse practitioner orders 1 liter of 0.9% normal saline to infuse over 6 hours. How many milliliters per hour will the nurse program the IV infusion device? Round off.

160 ml/hr

125 ml/hr

100 ml/hr

167 ml/hr

Answer and Explanation

The Correct Answer is D

To calculate the milliliters per hour (mL/hr) for the IV infusion, you divide the total volume (in milliliters) by the total time (in hours).

In this case, the total volume is 1 liter, which is equal to 1000 milliliters, and the total time is 6 hours.

So, you divide 1000 mL by 6 hours:

1000 mL / 6 hours = 166.67 mL/hr

Rounding off, the nurse will program the IV infusion device to infuse at approximately 167 mL/hr.

Correct Answer is B

Explanation

An increased serum potassium level, also known as hyperkalemia, can have adverse effects on the electrical conduction of the heart, potentially leading to life-threatening cardiac dysrhythmias. Therefore, it is crucial to assess the patient's pulse rate and rhythm promptly to identify any abnormal cardiac activity.

Assessing the oxygen saturation (oxygen stats), respiratory rate and depth, and deep tendon reflexes are also important assessments, but they are not the priority in this case. Hyperkalemia primarily affects cardiac function, and prompt identification of any potential cardiac rhythm disturbances is essential to prevent further harm.

A. administration of antiemetics B. administration of diuretics C. Possible Electrolyte replacement if warranted D. Administration of IV 0.9 Saline Solution infusion E. Have the patient go home and rest. It will resolve itself shortly.

Correct Answer is D

Explanation

Mrs. Kalen is diagnosed with gastroenteritis and dehydration, and the arterial blood gas results indicate metabolic alkalosis (elevated pH and HCO3-). This suggests that there is an excessive loss of gastric acid and chloride ions from vomiting, leading to an imbalance of electrolytes and an increase in bicarbonate levels.

To correct the imbalance and treat dehydration, the primary intervention is fluid replacement. Administration of IV 0.9 Saline Solution, also known as normal saline, is commonly used for fluid resuscitation and rehydration. This isotonic solution helps restore fluid balance and electrolyte levels in the body.

Administration of antiemetics may help control vomiting, but the primary treatment focus in this case is fluid and electrolyte replacement to correct dehydration and the associated metabolic alkalosis.

Administration of diuretics, which increase urine output, would not be appropriate in this case as the patient is already experiencing dehydration.

Electrolyte replacement may be necessary if there are specific electrolyte imbalances identified, but the primary treatment is fluid replacement with IV saline solution.

Having the patient go home and rest without addressing the underlying dehydration and metabolic alkalosis would not be appropriate as it can lead to further complications.
