A nurse is preparing to administer erythromycin 2 g PO daily in equally divided doses every 6 hr. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["500"]

To calculate the dose of erythromycin per administration, you can follow these steps:
 
-    Determine the total daily dose: 2 g.

-    Divide the total daily dose by the number of equally divided doses per day: 2 g / 4 doses =

0.5 g per dose.

-    Convert grams to milligrams: 0.5 g * 1000 mg/g = 500 mg.


So, the nurse should administer 500 mg of erythromycin per dose.

Correct Answer is ["1.5"]

Explanation

Convert the client's weight from pounds to kilograms by dividing by 2.2. 198 lb / 2.2 = 90 kg

Calculate the dose of filgrastim in micrograms by multiplying the client's weight in kilograms by the prescribed dose per kilogram. 90 kg x 5 mcg/kg = 450 mcg

Calculate the volume of filgrastim in milliliters by dividing the dose in micrograms by the concentration of the available solution. 450 mcg / 300 mcg/mL = 1.5 mL

Round the answer to the nearest tenth. The nurse should plan to give 1.5 mL of filgrastim with each dose.

Correct Answer is B

Explanation

A. “I will consume foods that are soft or semisolid." While soft or semisolid foods may be easier to eat if the gums are sore, dietary modifications are not the primary focus of gingivitis management. Proper oral hygiene and avoiding irritants are more crucial. B. "I will avoid consuming alcoholic beverages." Alcohol can contribute to oral irritation, dry mouth, and worsening gingivitis. Avoiding alcohol helps reduce gum inflammation and promotes healing. C. “I will perform oral hygiene using a firm-bristle toothbrush." A firm-bristle toothbrush can cause gum irritation and worsen gingival inflammation. A soft-bristle toothbrush is recommended to clean the teeth effectively while protecting the gums. D. “I will rinse my mouth with saline every 2 hours while awake." Although saline rinses can help with minor oral irritation, frequent rinsing is not necessary for gingivitis. Instead, proper brushing, flossing, and using an antimicrobial mouthwash are more effective in managing the condition.
