You are instructed to administer tobramycin 35mg IM every 8 hours. The available supply is 40mg in a 1 mL vial.
How many mL’s should the nurse administer? Round your answer to the nearest tenth. Use a leading zero if it applies.
Do not use a trailing zero.
The Correct Answer is ["0.9 "]
Step 1: We are instructed to administer tobramycin 35mg IM every 8 hours. The available supply is 40mg in a 1 mL vial.
Step 2: We need to find out how many mL’s should the nurse administer. Step 3: We can set up a proportion to solve this.
Step 4: If 40mg is equivalent to 1mL, then 35mg is equivalent to x mL. Step 5: Solving for x gives us x = (35mg ÷ 40mg) × 1mL.
Step 6: Calculating the above expression gives us x = 0.875 mL.
Step 7: Rounding our answer to the nearest tenth, we get 0.9 mL. So, the nurse should administer 0.9 mL.

Correct Answer is B
Explanation
Choice B rationale
If a patient states that he cannot see the top of the Snellen chart, the nurse should determine whether the patient can count fingers. If the patient is unable to read the top line of the Snellen
chart at 6 meters, the nurse can reduce the distance to 3 meters from the Snellen chart. If the patient still cannot read the chart, the nurse can then determine whether the patient can count fingers.
Choice A rationale
While documenting findings is an important part of the nursing process, it would not be the immediate action the nurse should take if a patient cannot see the top of the Snellen chart.
Choice C rationale
Obtaining a tumbling E chart to assess visual acuity could be considered if the patient is unable to read letters or numbers, but it would not be the immediate action the nurse should take if a patient cannot see the top of the Snellen chart.
Choice D rationale
Completing an internal eye exam would not be the immediate action the nurse should take if a patient cannot see the top of the Snellen chart.
Correct Answer is B
Explanation
Choice A rationale
Instilling mineral oil into the canal and immediately irrigating to remove the impacted wax is not typically recommended. This approach may not allow enough time for the mineral oil to soften the cerumen, making it more difficult to remove and potentially causing discomfort or injury.
Choice B rationale
Instilling a small amount of mineral oil into the canal, then having the patient return in 30 minutes for wax removal is a common and effective method for managing cerumen impaction. The mineral oil helps to soften the cerumen, making it easier to remove through irrigation.
Choice C rationale
Irrigating the ear with cold water is not typically recommended. Cold water can cause discomfort and potentially lead to vertigo.
Choice D rationale
Irrigating the ear with warm water and a high amount of otic pressure is not typically recommended. High pressure can potentially damage the ear canal or tympanic membrane.
