Correct Answer is ["6.7"]

Explanation

Step 1: Convert the total daily dose from grams to milligrams. 1.2 grams × 1000 = 1200 milligrams Result: 1200 milligrams

Step 2: Divide the total daily dose by the number of doses per day to find the dose per administration. 1200 milligrams ÷ 3 = 400 milligrams per dose Result: 400 milligrams per dose

Step 3: Determine how many milliliters are needed for each dose. The medication is supplied as 300 mg/5 mL. 400 milligrams ÷ 300 milligrams = (400 ÷ 300) = 1.3333 Result: 1.3333

Step 4: Multiply the result by the volume (5 mL) to find the volume needed per dose. 1.3333 × 5 mL = 6.6665 mL Result: 6.6665 mL

Step 5: Round the result to the nearest tenth. 6.6665 mL rounded to the nearest tenth = 6.7 mL Result: 6.7 mL

The nurse will administer 6.7 mL per dose.

A. Family history B. Weight C. Sedentary lifestyle D. Alcohol consumption

Correct Answer is ["B"]

Explanation

Choice A Reason: Family history

Family history is not a modifiable risk factor. It refers to the genetic predisposition to certain health conditions based on the medical history of one’s family. While it is important to be aware of family history to understand potential risks, it cannot be changed or modified through lifestyle adjustments.

Choice B Reason: Weight

Weight is a modifiable risk factor. Maintaining a healthy weight through diet and exercise can significantly reduce the risk of various health conditions, including heart disease, diabetes, and hypertension. Weight management is crucial for overall health and can be controlled through lifestyle changes.

Choice C Reason: Sedentary lifestyle

A sedentary lifestyle is a modifiable risk factor. Increasing physical activity and reducing sedentary behavior can improve cardiovascular health, enhance mental well-being, and reduce the risk of chronic diseases. Encouraging regular exercise and active living is essential for health improvement.

Choice D Reason: Alcohol consumption

Alcohol consumption is a modifiable risk factor. Limiting or avoiding alcohol can reduce the risk of liver disease, certain cancers, and other health issues. Moderation in alcohol intake is important for maintaining good health and preventing related complications.
