The practical nurse (PN) is preparing cefazolin 400 mg IM for a client with a gram-positive infection. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, for IM use, add 2 mL sterile water for injection. The total volume after reconstitution is 2.5 mL.
After reconstitution, how many mL should be administered to the client?
(Enter numeric value only. If rounding is required, round to the whole number, nearest tenths/hundredth).
The Correct Answer is ["1"]
The concentration of cefazolin after reconstitution can be calculated as follows: Concentration = Total amount of drug / Total volume after reconstitution
Since the available vial contains 1 gram (1000 mg) of cefazolin and the total volume after reconstitution is 2.5 mL, we can calculate the concentration:
Concentration = 1000 mg / 2.5 mL = 400 mg/mL
Therefore, after reconstitution, the concentration of cefazolin is 400 mg/mL.
To administer a dose of 400 mg, we divide the desired dose by the concentration: Volume to administer = Desired dose / Concentration
Volume to administer = 400 mg / 400 mg/mL = 1 mL

Correct Answer is D
Explanation
- Child abuse is the intentional or neglectful physical, emotional, or sexual harm or injury of a child by a parent, caregiver, or other person who has a relationship of trust or responsibility with the child. Child abuse can have serious and long-lasting consequences for the child's health, development, and well-being.
- The practical nurse (PN) has a legal and ethical duty to identify, report, and prevent child abuse. The PN should be alert for any signs and symptoms of child abuse, such as unexplained or inconsistent injuries, bruises, burns, fractures, or scars; behavioral changes, such as fear, anxiety, aggression, withdrawal, or depression; poor hygiene, nutrition, or growth; lack of supervision, medical care, or education; or sexualized behaviors or knowledge .
- The PN should also conduct a thorough and sensitive assessment of the child and the family situation, using open-ended questions, active listening, and non-judgmental attitude. The PN should compare the history and physical findings of the child with the expected developmental milestones and normal variations for the child's age and stage. The PN should also document any relevant information in an objective and factual manner .
- When the mother of a school-aged boy tells the PN that he fell out of a tree and hurt his arm and shoulder, the PN should assess the child's injury and compare it with the mother's explanation. The most significant indicator of possible child abuse in this scenario is if the injury description by the mother varies from the child's version. This may suggest that the mother is lying or covering up the true cause of the injury, which may be intentional or accidental harm by herself or someone else. A discrepancy between the mother's and the child's stories may also indicate that the child is afraid or coerced to hide the truth about the abuse .
- Therefore, option D is the correct answer, while options A, B, and C are incorrect.
Correct Answer is B
Explanation
Monitoring the client's vital signs, including temperature, heart rate, respiratory rate, and blood pressure, is crucial to assess for any signs of infection or complications following surgery.
A. While fluid volume intake and output are important to monitor for overall hydration status, it is not the most immediate concern after reinforcing the dressing.
C. Similarly, assessing the volume of peripheral pulses is important to evaluate peripheral perfusion, but it may not be the highest priority at this time.
D. Incisional pain scale rating is important to assess the client's comfort and pain level, but it should be done after ensuring the security of the surgical dressing.
