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 D
Explanation
Choice A rationale:
Respiratory acidosis is characterized by a low pH (less than 7.35), a high PaCO2 (greater than 45 mm Hg), and a normal or high HCO3 (22-26 mEq/L). It occurs when there is a buildup of carbon dioxide in the blood due to impaired ventilation.
The patient's ABGs do not align with respiratory acidosis because the pH is elevated (7.6), and the PaCO2 is within the normal range (40 mm Hg).
Choice B rationale:
Respiratory alkalosis is characterized by a high pH (greater than 7.45), a low PaCO2 (less than 35 mm Hg), and a normal or low HCO3 (22-26 mEq/L). It occurs when there is excessive loss of carbon dioxide through hyperventilation.
The patient's ABGs do not align with respiratory alkalosis because the HCO3 is elevated (32 mEq/L), which is not typical for this condition.
Choice C rationale:
Metabolic acidosis is characterized by a low pH (less than 7.35), a normal or low PaCO2 (less than 40 mm Hg), and a low HCO3 (less than 22 mEq/L). It occurs when there is an excess of acid in the body or a loss of bicarbonate.
The patient's ABGs do not align with metabolic acidosis because the pH is elevated (7.6), and the HCO3 is elevated (32 mEq/L).
Choice D rationale:
Metabolic alkalosis is characterized by a high pH (greater than 7.45), a normal or high PaCO2 (40-45 mm Hg), and an elevated HCO3 (greater than 26 mEq/L). It occurs when there is an excess of bicarbonate in the body or a loss of acid.
The patient's ABGs align with metabolic alkalosis because of the high pH (7.6), normal PaCO2 (40 mm Hg), and elevated HCO3 (32 mEq/L).
Correct Answer is A
Explanation
Choice A rationale
Speaking slowly and clearly using yes/no questions one at a time can help facilitate communication with a client diagnosed with aphasia.
Choice B rationale
Asking a family member if they know what the client wants may not always be effective, as the client may have difficulty expressing their needs even to family members.
Choice C rationale
Repeating the same question multiple times may not be effective and could potentially frustrate the client.
Choice D rationale
Putting a cell phone in their right hand to text their questions assumes that the client has the ability to text, which may not be the case for all clients diagnosed with aphasia.
