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.)
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 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.
Correct Answer is D
Explanation
A. Auscultate the bowel sounds in all four quadrants:
Auscultating bowel sounds is not directly relevant to nasopharyngeal suctioning. This assessment is more appropriate for evaluating gastrointestinal function and is not a priority during airway management procedures.
B. Palpate the client's pedal pulse volume bilaterally:
Palpating pedal pulse volume is not directly relevant to nasopharyngeal suctioning. This assessment is more appropriate for evaluating peripheral vascular perfusion and is not a priority during airway management procedures.
C. Determine the elasticity of the client's skin turgor:
Assessing skin turgor elasticity is not directly relevant to nasopharyngeal suctioning. This assessment is typically performed to evaluate hydration status and is not a priority during airway management procedures.
D. Observe the client's skin and mucous membranes:
This is the most appropriate assessment during nasopharyngeal suctioning. Observing the client's skin and mucous membranes helps monitor for signs of respiratory distress, such as cyanosis, pallor, or increased respiratory effort. It also allows the nurse to assess the effectiveness of airway clearance and potential complications related to the procedure.
