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 A
Explanation
Hoarseness or voice changes after thyroidectomy can be indicative of injury or irritation to the recurrent laryngeal nerve, which is responsible for controlling the vocal cords. This is a potential complication of the surgery and should be reported to the charge nurse or healthcare provider for further evaluation and management.
B. Administer humidified oxygen per nasal cannula: This option is not appropriate for addressing hoarseness in a client following a thyroidectomy. Hoarseness after a thyroidectomy is typically related to vocal cord injury or irritation, and providing humidified oxygen would not directly address this issue. It is important to notify the charge nurse or healthcare provider for further evaluation and management.
C. Obtain a cup of ice chips for the client: Providing ice chips is not the appropriate action for hoarseness following a thyroidectomy. Ice chips are typically used to provide hydration and comfort to clients, but they do not directly address the underlying cause of hoarseness, which in this case may be vocal cord injury or irritation. It is important to notify the charge nurse or healthcare provider for appropriate evaluation and management.
D. Ensure that the drainage device is compressed: While ensuring proper compression of a drainage device is important for preventing complications such as bleeding or infection, it is not directly related to the client's hoarseness. Hoarseness after a thyroidectomy is more likely related to vocal cord injury or irritation, and notifying the charge nurse or healthcare provider is necessary for further assessment and management.
Correct Answer is D
Explanation
When a client's family member expresses concerns about the care provided, it is essential for the nurse to gather more information and understand the specific issues raised. By asking for a description of what happened during the night, the nurse can obtain details about the perceived inadequate care. This allows the nurse to gather accurate information, assess the situation, and address any legitimate concerns.
A. Explaining that all staff are doing their best may not address the specific issues raised by the daughter and may not provide a satisfactory resolution to her concerns.
B. Telling the daughter to talk with the unit's nurse manager can be an appropriate step, but it should come after gathering information about the situation. The nurse needs to have a clear understanding of what happened before involving the nurse manager.
C. Reassuring the daughter that the mother will get better care may not address her concerns and may not provide a solution to the perceived problem. It is important to gather more information before offering reassurance or making promises.
