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.
Answer and Explanation

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 C

Explanation

Choice A rationale

Assessing lung sounds is an important part of monitoring a patient’s respiratory status, but it may not be the most immediate action if the patient is finding it increasingly difficult to breathe.

Choice B rationale

While explaining the progression of the syndrome is important for patient education, it may not be the most immediate action if the patient is experiencing difficulty breathing.

Choice C rationale

Guillain-Barre syndrome can affect the muscles used for breathing, resulting in a weakened or paralyzed diaphragm, which can lead to an ineffective breathing pattern. Therefore, if a patient states that it is getting harder to take a deep breath, the nurse should call the physician and prepare for possible intubation.

Choice D rationale

Encouraging the client to cough may not be the most appropriate action if the patient is finding it increasingly difficult to breathe.

Correct Answer is ["56"]

Explanation

Step 1 is to calculate the total drops per hour. This is done by multiplying the total volume of the solution by the drop factor and then dividing by the total time in minutes. So, (1000 mL × 10 gtt/mL) ÷ 180 min = 55.56 gtt/min. The final calculated answer is approximately 56 gtt/min when rounded to the nearest whole number.
