A nurse is assessing a client who is receiving metoprolol. Which of the following indicates a therapeutic effect?

Step 1: Determine the dosage available per mL.

• The available dosage is 75 mg per 5 mL.
• To find the dosage per mL, divide 75 mg by 5 mL.
• 75 mg ÷ 5 mL = 15 mg/mL.
• Result: 15 mg/mL.

Step 2: Determine how many mL are needed for the prescribed dose.

• The prescribed dose is 225 mg.
• To find the required mL, divide 225 mg by the dosage per mL (15 mg/mL).
• 225 mg ÷ 15 mg/mL = 15 mL.
• Result: 15 mL.

So, the nurse should administer 15 mL of clindamycin palmitate oral suspension every 8 hours.

Choice A reason: Use Wool Blankets on Your Bed

Using wool blankets is not recommended for clients on home oxygen therapy. Wool and other materials that can generate static electricity pose a fire hazard when used around oxygen. Instead, clients should use cotton or other non-static generating materials to reduce the risk of fire.

Choice B reason: Do Not Adjust the Oxygen Flow Rate

This statement indicates an understanding of the teaching. Clients should not adjust the oxygen flow rate unless instructed by their healthcare provider. The prescribed flow rate is set to meet the client’s specific needs, and any changes could lead to inadequate oxygenation or other complications.

Choice C reason: Store Unused Oxygen Tanks Horizontally

This statement is incorrect. Oxygen tanks should be stored upright and secured to prevent them from falling over. Storing tanks horizontally can increase the risk of damage and potential leaks, which can be hazardous.

Choice D reason: Check Your Oxygen Equipment Once Each Week

While it is important to regularly check oxygen equipment, doing so only once a week may not be sufficient. Clients should check their equipment daily to ensure it is functioning properly and to identify any issues that need to be addressed promptly.
