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 A
Explanation
Choice A rationale
Maslow's hierarchy of needs is a framework that prioritizes human needs in a hierarchical order, starting with physiological needs, followed by safety, love and belonging, esteem, and self-actualization. In the planning phase of nursing, this framework helps nurses to establish priorities of care by addressing the most basic and urgent needs first before moving to higher-level needs.
Choice B rationale
Piaget's cognitive developmental theory describes the stages of intellectual development in children and adolescents. While understanding cognitive development can inform nursing care, it is not the primary framework used for establishing priorities of care during the planning phase.
Choice C rationale
Erikson's stages of psychosocial development outline the social and emotional challenges individuals face across the lifespan. While relevant to understanding a client's psychosocial well-being, it is not the primary framework for prioritizing immediate nursing interventions in the planning phase.
Choice D rationale
Kohlberg's stages of moral development describe the progression of moral reasoning. While understanding a client's moral perspective can be relevant in certain situations, it is not the central framework used for establishing the priorities of physiological and safety needs in the nursing care plan. .
Correct Answer is B
Explanation
Choice A rationale
While electronic medical records (EMRs) improve legibility by using standardized digital text, they do not entirely eliminate the need to interpret physician notes or potential data entry errors. Clinicians still input information, and nuances in terminology or abbreviations can require careful review. EMRs primarily address the issue of illegible handwriting associated with paper-based records.
Choice B rationale
Electronic medical record systems streamline documentation processes by offering templates, drop-down menus, and the ability to copy forward information. This reduces the need for repetitive manual charting, freeing up nurses' time for direct patient care and other essential tasks. Efficient data entry and retrieval contribute significantly to time savings in documentation.
Choice C rationale
Password management is a security feature of computer systems, including EMRs, and often requires periodic changes to protect patient data. Implementing a new EMR system does not typically eliminate the need for password changes; in fact, it might introduce new password protocols. Security protocols necessitate regular password updates to maintain data integrity and confidentiality.
Choice D rationale
Accessing a family member's medical record violates patient privacy and confidentiality regulations, such as HIPAA. Nurses should only access records of patients for whom they are directly providing care. Viewing a son's medical record without a professional need is an ethical and legal breach of patient confidentiality.
