The nursing process is best defined as a framework for the organization of individualized nursing care.

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.

Choice A rationale

Maintaining a normal respiratory rate (typically 12-20 breaths per minute for adults) and pulse rate (typically 60-100 beats per minute for adults) are general indicators of stable physiological function but do not directly confirm airway clearance. While improved airway clearance can contribute to these stable vital signs, other factors can also influence them.

Choice B rationale

A clear airway directly addresses the nursing diagnosis of ineffective airway clearance. If the patient's airway remains unobstructed, thick sputum can be expectorated or managed, and narrowed airways will not impede airflow. This outcome specifically targets the problem identified in the nursing diagnosis.

Choice C rationale

Resting comfortably by the morning is a desirable outcome reflecting overall well-being, but it is not a direct measure of airway clearance. While improved breathing can contribute to comfort, other factors like pain or anxiety can also affect rest.

Choice D rationale

Absence of shortness of breath (dyspnea) and anxiety suggests improved respiratory function, but it doesn't definitively confirm the airway is clear of thick sputum or that narrowed airways are no longer a problem. The patient could still have airway issues without experiencing these symptoms consistently.
