(Enter numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["0.4"]

Step 1: Use the Formula

mL = units prescribed ÷ units per mL

Step 2: Plug in the Given Values

mL = 200,000 ÷ 500,000

Step 3: Simplify the Fraction

mL = 2 ÷ 5

Step 4: Convert the Fraction to a Decimal

mL = 0.4 mL

The nurse should administer 0.4 mL of penicillin to this client.

Correct Answer is B

Explanation

A. Return appointments will be needed for IV medication:
This statement does not address the specific concern related to pain management in Raynaud's disease, and routine IV medication may not be the primary approach for pain relief in this condition.

B. Wearing gloves when handling cold items guards against painful spasms:
This is the correct answer. Raynaud's disease is characterized by vasospasm of small arteries, often triggered by exposure to cold or stress. Wearing gloves helps to minimize exposure to cold and can prevent painful spasms associated with Raynaud's.

C. Enrolling in a pain clinic can provide pain relief alternatives:
While pain clinics can offer various pain management strategies, the specific recommendation for Raynaud's disease involves minimizing exposure to cold and stress rather than enrolling in a pain clinic.

D. Painful areas should be rubbed gently until the pain subsides:
Rubbing painful areas may not be recommended, as it can potentially aggravate vasospasm in individuals with Raynaud's disease. The emphasis is on preventing triggers like cold exposure.

A. Instruct the client to drink plenty of fluids during the treatment. B. Keep the head of the bed elevated until the treatment is completed. C. Monitor the client's intravenous site hourly during the treatment. D. Administer an antiemetic before starting the chemotherapy.

Correct Answer is C

Explanation

A. Instruct the client to drink plenty of fluids during the treatment.
This option focuses on hydration, which is generally important during chemotherapy to flush out toxins and maintain overall health. However, it does not specifically address the risk of vesicant extravasation.

B. Keep the head of the bed elevated until the treatment is completed.
Keeping the head of the bed elevated is a measure that may be taken for certain conditions or treatments, but it is not directly related to preventing vesicant extravasation.

C. Monitor the client's intravenous site hourly during the treatment.
This is the correct choice. Monitoring the intravenous site for signs of extravasation, such as swelling, redness, or pain, is crucial when administering vesicant chemotherapy drugs. Early detection allows for prompt intervention to minimize potential tissue damage.

D. Administer an antiemetic before starting the chemotherapy.
Administering an antiemetic (a medication to prevent or alleviate nausea and vomiting) is important for managing side effects of chemotherapy, but it does not specifically address the prevention of vesicant extravasation.
