The healthcare provider prescribes penicillin 200, 000 units intramuscularly for a client with pneumonia. The available vial is labeled, "Penicillin 500,000 units/mL". How many mL should the nurse administer to this client?
(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 D

Explanation

A. Elevate extremities on pillows:
While elevation can be beneficial for reducing dependent edema, the priority is to assess the pulses first to determine the adequacy of peripheral perfusion.

B. Evaluate edema for pitting:
Assessing edema for pitting is important for gathering additional information, but it is not the initial action in this scenario. Assessing pulses is more critical to evaluate perfusion.

C. Wrap the feet with warmed blankets:
Warming the feet with blankets may be appropriate in some situations, but it is not the priority when the client is exhibiting edema and non-palpable pedal pulses. The primary concern is assessing perfusion.

D. Assess pulses with a vascular Doppler:
This is the correct action. The non-palpable pedal pulses are concerning and require immediate assessment to determine the status of peripheral perfusion. Using a vascular Doppler will help the nurse assess the presence or absence of blood flow in the lower extremities.

A. Guidelines for oxygen use. B. Methods for weight loss. C. Approaches to conserve energy. D. Strategies for smoking cessation.

Correct Answer is D

Explanation

A. Guidelines for oxygen use:
While guidelines for oxygen use are important, addressing the root cause of the respiratory condition, which includes smoking cessation, is crucial for long-term management.

B. Methods for weight loss:
Obesity can contribute to respiratory issues, but in the immediate context of emphysema exacerbation and the need for oxygen therapy, smoking cessation is a more urgent concern.

C. Approaches to conserve energy:
Conserving energy is important for clients with emphysema, but addressing the impact of smoking on respiratory function is a more immediate priority.

D. Strategies for smoking cessation.
Smoking is a major contributor to the progression of emphysema and exacerbation of respiratory symptoms. Addressing smoking cessation is crucial in improving the client's respiratory function and overall health. Continuing to smoke can exacerbate emphysema and compromise the effectiveness of other interventions, including oxygen therapy.
