Correct Answer is ["2"]

Explanation

To calculate the volume of chlorpromazine to administer per dose, we'll use the formula:

Volume(mL)=Totaldoseneeded(mg)/Concentrationofthemedication(mg/mL)

Given: Total dose needed per dose = 50 mg

Concentration of chlorpromazine injection = 25 mg/mL

Substituting the given values into the formula:

Volume(mL)=50 mg/25 mg/mL

Volume(mL)=2 mL

Rounded to the nearest whole number, the nurse should administer 2 mL of chlorpromazine per dose.

A. Tap the top of the ampule. place a sterile gauze pad around the ampule neck, and break off the top by bending it toward the body. B. Tap the bottom of the ampule, place a gauze pad around the ampule neck, and break off the bottom with a forward motion away from the body. C. Wear sterile gloves and break off the neck of the glass ampule with a single snap in a downward motion. D. Wear sterile gloves and break off the neck of the glass ampule with a single snap to the right side.

Correct Answer is A

Explanation

When opening a glass ampule, it's essential to use the correct technique to prevent injury and ensure sterility. Here's the rationale for each option:

A. Tap the top of the ampule, place a sterile gauze pad around the ampule neck, and break off the top by bending it toward the body: This technique is correct. Tapping the top of the ampule helps dislodge any medication that may be trapped in the neck. Placing a sterile gauze pad around the neck provides a barrier to protect against injury from glass shards. Breaking off the top by bending it toward the body helps prevent spillage of the medication.

B. Tap the bottom of the ampule, place a gauze pad around the ampule neck, and break off the bottom with a forward motion away from the body: Tapping the bottom of the ampule is unnecessary and may increase the risk of breakage. Breaking off the bottom with a forward motion away from the body is not the recommended technique for opening a glass ampule.

C. Wear sterile gloves and break off the neck of the glass ampule with a single snap in a downward motion: This technique does not involve the use of a gauze pad to protect against injury, which is essential for safe medication administration.

D. Wear sterile gloves and break off the neck of the glass ampule with a single snap to the right side: Breaking off the neck with a single snap to the right side is not a recommended technique. Additionally, using sterile gloves alone may not provide sufficient protection against injury from glass shards.
