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 ["0.4ml"]

To answer this question, you need to use the formula:

mL = units prescribed / units per mL

Plug in the given values:

mL = 200,000 / 500,000

Simplify the fraction:

mL = 2 / 5

Convert the fraction to a decimal:

mL = 0.4

Therefore, the nurse should administer 0.4 mL of penicillin to this client.

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.

A. Have the client sign the surgical and transfusion permits. B. Ensure that the potential for bleeding is explained to the client C. Observe the heparin injections sites for signs of bruising. D. Notify the healthcare provider of the client's medication history.

Correct Answer is D

Explanation

A. Have the client sign the surgical and transfusion permits:
While obtaining signed consent is important, the immediate concern is addressing the client's medication history, especially the use of heparin, which can contribute to bleeding.

B. Ensure that the potential for bleeding is explained to the client:
Education about the potential for bleeding is important, but the immediate action is to communicate the client's medication history to the healthcare provider for appropriate guidance.

C. Observe the heparin injection sites for signs of bruising:
Monitoring for bruising at injection sites is a consideration, but it is not the priority when the client is actively bleeding from an open fracture.

D. Notify the healthcare provider of the client's medication history:
This is the correct answer. Heparin is an anticoagulant, and its use can increase the risk of bleeding during surgery. The healthcare provider needs to be informed of the client's current medication history to make decisions regarding the timing and management of heparin therapy in the perioperative period.
