The physician orders 350,000 units of Penicillin G IM now for a patient with a positive strep infection.
What is the most appropriate diluent amount for this patient? See LABEL #1 (Penicillin G)
The Correct Answer is ["9.6"]
Step 1 is: Locate the section on the Penicillin G label that provides reconstitution instructions for intramuscular (IM) injection.
Step 2 is: Identify the desired dose of Penicillin G, which is 350,000 units.
Step 3 is: Examine the label to find the different dilution options and the resulting concentration (units/mL) for IM administration. The label provides the following reconstitution guidelines for IM injection:. Add 9.6 mL of sterile water for injection to yield 1,000,000 units/mL (Total volume: 10 mL). Add 4.6 mL of sterile water for injection to yield 2,000,000 units/mL (Total volume: 5 mL).
Step 4 is: Determine which dilution would be most appropriate for administering 350,000 units. Using the 1,000,000 units/mL concentration:. Volume to administer = Desired dose ÷ Concentration. Volume to administer = 350,000 units ÷ 1,000,000 units/mL = 0.35 mL. Using the 2,000,000 units/mL concentration:. Volume to administer = Desired dose ÷ Concentration. Volume to administer = 350,000 units ÷ 2,000,000 units/mL = 0.175 mL.
Step 5 is: Consider the practicalities of administering such small volumes. While both are technically correct, administering 0.35 mL is generally easier and more accurate than 0.175 mL with standard syringes. Therefore, diluting to yield 1,000,000 units/mL is the more appropriate choice. The question asks for the most appropriate diluent amount, which corresponds to this concentration. To achieve a concentration of 1,000,000 units/mL, 9.6 mL of diluent should be added.
Final Answer: The most appropriate diluent amount is 9.6 mL of sterile water for injection to yield a concentration of 1,000,000 units/mL, and then administer 0.35 mL.

Related Questions
Correct Answer is B
Explanation
Choice A rationale
Sharing information only with family members violates confidentiality unless the patient has provided explicit consent. The Health Insurance Portability and Accountability Act (HIPAA) protects patient health information from unauthorized disclosure, even to family, without patient permission.
Choice B rationale
Adherence to confidentiality principles mandates that healthcare professionals access patient medical records only when there is a legitimate clinical reason related to the provision of care for that specific patient. Accessing records out of curiosity or without a direct care responsibility is a breach of confidentiality.
Choice C rationale
Providing information only to another nurse is too restrictive. Confidentiality allows for the sharing of necessary patient information with all members of the healthcare team directly involved in the patient's care, not just nurses.
Choice D rationale
Providing information only to an attorney is incorrect. While patient records may be disclosed to attorneys in specific legal situations with proper authorization (e.g., subpoena, patient consent), healthcare professionals can also share information with other authorized individuals involved in the patient's care.
Correct Answer is D
Explanation
Choice A rationale
Using correction tape is inappropriate as it obscures the original entry, violating the principle of maintaining a clear and accurate audit trail. This makes it impossible to determine what the original error was and who made it, which is crucial for accountability and legal purposes in healthcare documentation.
Choice B rationale
Shredding the original forms and rewriting them is unacceptable because it completely eliminates the original record. This action could be interpreted as an attempt to conceal errors or misrepresent information, which carries significant legal and ethical implications in patient care documentation.
Choice C rationale
Blacking out the error with a thick marker obscures the original information, making it impossible to review the mistake and understand the context. This method does not allow for verification of the initial entry or tracking of the correction process, which is essential for maintaining accurate medical records.
Choice D rationale
Drawing a single line through the incorrect information, making the correction clearly beside it, and then initialing and dating the change maintains the integrity of the original record while indicating who made the correction and when. This method ensures transparency and accountability in documentation, adhering to legal and professional standards for error correction in medical charts.
