The healthcare provider prescribes streptomycin 200 mg IM every 12 hours. The vial is labeled, "Streptomycin 1 gram/2.5 mL." How many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["0.5"]

To find out how many milliliters the nurse should administer, we first need to calculate the volume required to deliver 200 mg of streptomycin.

Given:

Streptomycin concentration: 1 gram/2.5 mL

Dose prescribed: 200 mg

We'll start by converting the dose prescribed from milligrams (mg) to grams (g) since the concentration is given in grams:

200 mg = 0.2 grams

Now, we can set up a proportion to find the volume (x) needed to deliver 0.2 grams of streptomycin:

1 gram / 2.5 mL = 0.2 grams / x

Cross-multiplying:

1 * x = 0.2 * 2.5

x = 0.5 mL

So, the nurse should administer 0.5 milliliters of streptomycin.

Correct Answer is D

Explanation

A. Withdraw the medication into a syringe and label it with the client's name:

This is not necessary for the remainder of the medication. The medication should not be withdrawn into a syringe for future use or left labeled, as it could lead to errors or contamination.

B. Throw the vial into the trash in the presence of another nurse:

Discarding the vial into the trash is not appropriate, as it does not ensure proper documentation, accountability, or safe storage of the remaining medication. Additionally, the presence of another nurse does not address these concerns.

C. Place the vial with the remainder of the medication into a locked drawer:

While storing the vial in a locked drawer may prevent unauthorized access, it does not address the need for proper documentation and labeling of the remaining medication. Additionally, the vial should not be stored with the medication still in it after withdrawal.

D. Ask another nurse to witness the medication being discarded:

This is the appropriate action. Many facilities require that the disposal of unused or remaining medications, especially controlled substances, be witnessed by another nurse to ensure accountability and compliance with regulations.

A. Places food on the unaffected side of the mouth. B. Raises the head of the bed to 60 degrees. C. Positions the head with the chin tilted slightly downward. D. Allows 30 minutes of rest before feeding.

Correct Answer is B

Explanation

A. Places food on the unaffected side of the mouth:

This is correct practice for clients at risk for aspiration. Placing food on the unaffected side helps ensure safer swallowing.

B. Raises the head of the bed to 60 degrees:

Clients at risk for aspiration-especially after a CVA (stroke)-should have the head of the bed elevated to at least90 degrees during feeding.60 degrees is insufficient to fully protect the airway and reduce the risk of aspiration.

C. Positions the head with the chin tilted slightly downward:

Positioning the head with the chin tilted slightly downward (chin tuck) helps close off the airway during swallowing, further reducing the risk of aspiration. This is another appropriate technique to minimize the risk of aspiration during feeding.

D. Allows 30 minutes of rest before feeding:

Resting reduces fatigue, which can improve swallowing safety and coordination.
