Answer and Explanation

The Correct Answer is ["0.5"]

· Convert grams to milligrams: 1 gram = 1000 mg

· Determine the concentration: The vial contains 1000 mg of streptomycin in 2.5 mL of solution.

· Set up a proportion: (Desired dose / Concentration) Volume = Amount to administer

(200 mg / 1000 mg) x 2.5 mL = X mL

· Solve for X: 0.2 x 2.5 mL = 0.5 mL

Correct Answer is D

Explanation

A. Elevate the head of the bed to a 45-degree angle may be helpful for some clients with OSA, but the most crucial intervention for a client with OSA is ensuring the proper use of the positive airway pressure (PAP) device.

B. Remove dentures or other oral appliance is not a priority for clients with OSA unless specifically contraindicated by the healthcare provider. The main concern is ensuring the PAP device is in place to prevent airway obstruction.

C. Lift and lock the side rails in place is a general safety measure, but it is not as critical as ensuring the client has their PAP device applied.

D. Apply the client's positive airway pressure device is the most important intervention. The PAP device (e.g., CPAP or BiPAP) helps keep the airway open during sleep, preventing apneas and improving oxygenation. Ensuring the client has this device in place is the most essential action before leaving the client alone.

A. Select upper arm as the injection site. B. Massage the site gently after injection. C. Ensure bevel of the needle is pointing up. D. Hold the syringe perpendicular to the skin.

Correct Answer is C

Explanation

A. Select upper arm as the injection site is incorrect. While the upper arm can be an appropriate site for an intradermal injection, the most common site for ID injections is the inner forearm. The choice of site depends on the procedure and provider's preferences.

B. Massage the site gently after injection is incorrect. Massaging the site after an intradermal injection can disrupt the injection, causing the medication to be dispersed under the skin rather than remaining in the dermis.

C. Ensure bevel of the needle is pointing up is the correct action. For intradermal injections, the bevel of the needle should be facing upward to ensure that the medication is injected just beneath the skin, creating a visible wheal.

D. Hold the syringe perpendicular to the skin is incorrect. For intradermal injections, the needle should be inserted at a 5-15 degree angle to the skin, not perpendicular.
