(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 ["20"]

Step 1: Convert Weight to Kilograms

  • 1 lb = 0.4536 kg
  • 132 lb × 0.4536 kg/lb = 59.87 kg

Step 2: Calculate Total Dose of Acyclovir

  • Prescribed dose = 10 mg/kg
  • Total dose = 59.87 kg × 10 mg/kg = 598.75 mg

Step 3: Determine the Volume of Injectable Solution

  • Acyclovir IV concentration = 30 mg/mL
  • Volume = 598.75 mg ÷ 30 mg/mL = 19.96 mL

The nurse should administer 20 mL (rounded to the nearest whole number) of acyclovir IV injectable solution.

Correct Answer is A

Explanation

A. Rotate the application site every week (Correct Answer): This is the correct advice. Rotating the application site helps prevent skin irritation and enhances absorption. It's common practice to apply the patch to a different, clean, and hairless area of the skin each time it is changed.
B. The transdermal patch releases nicotine rapidly into the bloodstream: This statement is incorrect. The transdermal nicotine patch is designed to release nicotine gradually over an extended period. It provides a steady, controlled release of nicotine to help manage withdrawal symptoms and cravings.
C. Leave the patch in place for 8 hr each day: The specific duration for wearing a nicotine patch can vary depending on the product. However, it's generally recommended to wear the patch for 16 to 24 hours, depending on the product's instructions. Leaving it on for 8 hours only may not provide adequate coverage for the entire day.
D. The transdermal patch can cause insomnia: While insomnia is a potential side effect of nicotine replacement therapy, including the patch, it is not a universal experience for everyone. Insomnia is more likely to occur if the patch is worn continuously, including during the night. Following proper usage guidelines, such as removing the patch before bedtime, can help minimize this side effect.

Correct Answer is ["400"]

Explanation

Step 1: Determine the Total Volume Needed

  • Supplied concentration: 300 mg/100 mL
  • Prescribed dose: 300 mg
  • Total volume needed = 100 mL

Step 2: Convert Time to Hours

  • Prescribed infusion time = 15 minutes
  • 15 minutes ÷ 60 minutes/hour = 0.25 hours

Step 3: Calculate the Infusion Rate (mL/hr)

  • Infusion rate = Total volume (mL) ÷ Time (hours)
  • Infusion rate = 100 mL ÷ 0.25 hours
  • Infusion rate = 400 mL/hr

The nurse should set the IV pump to deliver cimetidine at 400 mL/hr (rounded to the nearest whole number).
