the client has been prescribed a 4 gram bolus of magnesium sulfate to run over 20 minutes. it arrives from the pharmacy diluted in 250 ml of normal saline. what rate does the nurse set the iv pump to run the bolus? (enter a whole number, round as needed. )

Answers

Answer 1
Answer:

The nurse needs to set the IV pump to provide 4 grams of magnesium sulfate over a 20-minute period to run the bolus.

Since the bolus comes diluted in 250 mL of normal saline, the nurse needs to calculate the rate at which the bolus will be delivered. To do this, the nurse needs to divide the amount of magnesium sulfate (4 grams) by the time it should take to deliver the bolus (20 minutes). This gives a rate of 0.2 grams per minute.

However, since IV pumps deliver in milliliters per hour, the nurse needs to convert this rate to mL/hr. To do this, the nurse multiplies 0.2 grams/minute by 60 minutes/hour, giving a rate of 12 mL/hour. Therefore, the nurse should set the IV pump to 12 mL/hour to provide the 4-gram magnesium sulfate bolus over 20 minutes.

Answer 2
Answer:

The IV pump rate for a 4 gram bolus of magnesium sulfate to run over 20 minutes with a total volume of 250 mL should be set at 750 mL/hr.

To calculate the IV pump rate for a magnesium sulfate bolus of 4 grams to be administered over 20 minutes, we need to know the total volume of the IV fluid which is 250 mL.

Since the entire 250 mL should be administered in 20 minutes, we first convert minutes to hours because infusion pumps are calibrated in mL per hour. Thus, 20 minutes is ⅓ of an hour.

To find the infusion rate in mL/hour, we use the formula:

  • Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
  • Infusion rate = 250 mL / (⅓ hr)
  • Infusion rate = 250 mL / 0.333hr
  • Infusion rate = 750 mL/hr

Therefore, the nurse should set the IV pump to run at a rate of 750 mL/hr to administer a 4 gram bolus of magnesium sulfate diluted in 250 mL of normal saline over 20 minutes.

Which organ performs the given function? The roof of the mouth separates the oral cavity from the nasal cavity. The is flexible and closes off the nasal cavity when you swallow.

Answers

Soft palate


The soft palate is composed of muscle and connective tissue, which give it both mobility and support. This palate is very flexible. When elevated for swallowing and sucking, it completely blocks and separates the nasal cavity and nasal portion of the pharynx from the mouth and the oral part of the pharynx.

Final answer:

The palate separates the oral cavity from the nasal cavity, and comprises of two parts: the hard palate at the front and the soft palate at the back. The soft palate is flexible and closes off the nasal passage when we swallow.

Explanation:

The organ that separates the oral cavity from the nasal cavity is the palate. The palate comprises of two sections: the hard palate at the front, made of bone and the flexible soft palate at the back that closes off the nasal cavity when we swallow.

Essentially, the palate plays a significant role in our ability to eat and speak correctly. When we swallow, the soft part of the palate seals off the nasal passages, ensuring food and liquid pass from the oral cavity to the esophagus avoiding the nasal cavity.

Emulsification is a process where two liquids that do not mix are mixed, in digestion, it is the breaking down of fat globules in the duodenum into tiny droplets

Explanation:

The substance which performs emulsification is called bile

Bile is synthesized in the liver

Bile is stored and concentrated in the gallbladder

Once bile has been synthesized, it moves out of the liver through the hepatic ducts, the ducts (left and right) join to form the common hepatic duct which joins the duct from the gallbladder called the cystic duct. This bile duct enters the small intestine through a sphinter (Oddi) below the stomach.
