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 ["1"]

Explanation

To determine how many tablespoons the client should take with each dose, we need to first calculate the dosage in tablespoons based on the concentration of the oral suspension.

Given:

Dextromethorphan oral suspension concentration: 30 mg per 15 mL

To find out how many milliliters the client should take per dose:

The prescribed dose is 30 mg.

So, if 15 mL contains 30 mg, then 1 mL contains:

30 mg / 15 mL = 2 mg/mL

To find out how many milliliters the client should take for the prescribed dose:

30 mg / 2 mg/mL = 15 mL

Now, we know that the prescribed dose is 15 mL. To convert this to tablespoons, we can use the fact that 1 tablespoon (tbsp) is equal to 15 milliliters.

So, the client should take:

15 mL / 15 mL/tbsp = 1 tablespoon

Therefore, the nurse should instruct the client to take 1 tablespoon with each dose.

Correct Answer is C

Explanation

A. Suctions secretions from the posterior pharynx:

Suctioning secretions from the posterior pharynx is an appropriate action to maintain airway patency and prevent aspiration in an unconscious client. This action indicates proper understanding of oral care principles.

B. Tests for a gag reflex before performing oral care:

Testing for a gag reflex before performing oral care is an important safety measure, especially in unconscious clients, to prevent aspiration or airway obstruction. This action indicates proper assessment and consideration of the client's protective reflexes.

C. Places the client in a supine position:

Placing an unconscious client in a supine position during oral care can increase the risk of aspiration, as it may impair the client's ability to manage oral secretions. The preferred position for oral care in unconscious clients is typically a side-lying position to facilitate drainage of oral secretions and reduce the risk of aspiration.

D. Uses an oral airway to keep the teeth apart:

Using an oral airway to keep the teeth apart is not a standard practice for oral care in unconscious clients and may not be necessary. Proper positioning of the client's head and jaw manipulation can often provide adequate access for oral care without the need for an oral airway.
