The healthcare provider prescribes cefazolin 500 mg IM every 6 hours. The available vial is labeled, "Cefazolin 1 gram,”. and the instructions for reconstitution state, "For IM use, add 2.5 mL sterile water for injection to provide a total volume of 3.0 mL.”. After reconstitution, how many mL should be administered to the client? (Enter numeric value only. If rounding is required, round to the nearest tenth.).
The Correct Answer is ["1.5"]
Step 1: 1 gram = 1000 mg
Step 2: 500 mg ÷ 1000 mg = 0.5
Step 3: 0.5 × 3.0 mL = 1.5 mL

Correct Answer is C
Explanation
The correct answer is choice C. Suction the oral and nasal passages.
Choice A rationale:
Turning the infant onto the right side may not be the most appropriate intervention for cyanosis caused by regurgitation. Cyanosis signifies a lack of oxygen, and simply changing the infant's position might not address the underlying issue.
Choice B rationale:
Giving oxygen by positive pressure is not the immediate intervention needed for regurgitation-induced cyanosis. While administering oxygen is important, the first step should involve clearing the airway to ensure proper oxygenation.
Choice C rationale:
Suctioning the oral and nasal passages is crucial in this situation as the cyanosis is likely due to the infant's airway being obstructed by regurgitated material. Clearing the airway can restore normal breathing and oxygenation.
Choice D rationale:
Stimulating the infant to cry is not the appropriate action when cyanosis is present. Cyanosis indicates a serious problem with oxygenation, and crying may worsen the situation by further compromising the infant's breathing.
Correct Answer is A
Explanation
This is the best action for the PN to implement because it addresses the client's question and provides an opportunity to educate the client about fecal diversion surgery and its outcomes. The PN should review the type, location, and appearance of the surgical opening (stoma) and explain how it will affect the client's elimination and body image.
B. Verifying that the client had nothing by mouth (NPO) for the past 24 hours is not relevant to the client's question and does not provide any information or support.
C. Asking the client if he finished the bowel sterilization prescription is not relevant to the client's question and does not provide any information or support.
D. Determining if this is the first indwelling catheter the client has had is not relevant to the client's question and does not provide any information or support.
