A nurse is preparing to administer 0.9% sodium chloride (NS) 100 mL IV to infuse over 4 hr. The drip factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?
(Round the answer to the nearest whole number.)
Answer and Explanation

The Correct Answer is ["25"]

To calculate the infusion rate in drops per minute (gtt/min), we can use the following formula: Infusion rate (gtt/min) = (Volume to be infused (ml) * Drop factor) / Time (min) Given: 

Volume to be infused: 100 ml 

Drop factor: 60 gtt/ml 

Time: 4 hr 

First, we need to convert the time from hours to minutes: 

4 hr * 60 min/hr = 240 min 

Now, we can calculate the infusion rate: 

Infusion rate (gtt/min) = (100 ml * 60 gtt/ml) / 240 min 

Simplifying the equation: 

Infusion rate (gtt/min) = 6000 gtt / 240 min 

Dividing both sides: 

Infusion rate (gtt/min) ≈ 25 gtt/min

Correct Answer is ["2.5"]

Explanation

To determine how many milliliters (ml) should be administered per dose, we need to calculate the dose volume using the available concentration of famotidine.

Given:

Famotidine concentration: 40 mg/5 ml

Dose: 20 mg

We can set up a proportion to solve for the volume:

40 mg / 5 ml = 20 mg / x ml

Cross-multiplying the proportion, we get:

40 mg * x ml = 20 mg * 5 ml

Simplifying, we have:

40x = 100

Dividing both sides by 40, we find:

x = 100 / 40

x ≈ 2.5 ml

Therefore, the nurse should administer approximately 2.5 ml of famotidine per dose.

Correct Answer is ["A","D"]

Explanation

From the given statements, the nurse can identify the following statements as indicating the effectiveness of cimetidine treatment:

"I don't have as much heartburn after I eat anymore.": Cimetidine is a histamine-2 receptor antagonist commonly used to reduce stomach acid production. Decreased heartburn after eating suggests that the medication has been effective in reducing excessive acid production and relieving heartburn symptoms.

"I can sleep while lying flat again.": Cimetidine can help alleviate symptoms of gastroesophageal reflux disease (GERD) by reducing stomach acid. Improved ability to sleep while lying flat suggests that the medication has successfully reduced acid reflux and related symptoms.

The following statements do not directly indicate the effectiveness of cimetidine treatment: ● "I noticed that I have had less urge to smoke lately."

● "I occasionally have stomach pain and dark stools."

● "I have not been as dizzy as I was before."

These statements may be unrelated to the effects of cimetidine or may require further assessment to determine their significance. It's important for the nurse to address any concerns or symptoms mentioned by the client and evaluate their overall response to the medication
