A nurse is preparing to administer amoxicillin 350 mg PO. The available amoxicillin is 250 mg/5 mL. How many mL should the nurse administer? (Round to the nearest whole number.)
5 mL
6 mL
7 mL
8 mL
The Correct Answer is C
Step 1 is to calculate the amount of amoxicillin in milliliters. Step 2: We know that 250 mg of amoxicillin is in 5 mL.
Step 3: We need to find out how many mL contain 350 mg of amoxicillin. Step 4: Set up a proportion: 250 mg/5 mL = 350 mg/x mL.
Step 5: Cross-multiply and solve for x: 250x = 1750. Step 6: Divide both sides by 250: x = 7 mL2.

Correct Answer is C
Explanation
Choice A rationale
While involving the family in the care of an older adult client is important, calling the family to make arrangements for someone to sit with the client is not the immediate action the nurse should take. The nurse’s first responsibility is to ensure the client’s safety and well-being.
Choice B rationale
Obtaining a prescription for medication to sedate the client is not the immediate action the nurse should take. Sedating the client does not address the immediate concern of potential injury.
Choice C rationale
The nurse should first check the client for injuries. This is the immediate action because the client may have sustained injuries from the fall. The nurse should perform a thorough assessment to determine the extent of any injuries and provide appropriate care.
Choice D rationale
Assisting the client back into bed and applying restraints is not the immediate action the nurse should take. Restraints should be used as a last resort and only if less restrictive measures have been ineffective. Furthermore, restraints require a physician’s order.
Correct Answer is C
Explanation
Choice A rationale
Antimicrobial dressings are typically used for wounds that are infected or at high risk of infection. A stage I pressure ulcer, which involves intact skin with non-blanchable redness, would not typically require an antimicrobial dressing.
Choice B rationale
Wet-to-dry dressings are used for mechanical debridement of wounds with necrotic tissue. A stage I pressure ulcer does not involve necrotic tissue, so this type of dressing would not be appropriate.
Choice C rationale
Transparent dressings are often used for stage I pressure ulcers. They provide a protective layer over the wound, promoting a moist environment and facilitating the healing process.
Choice D rationale
Dry, sterile dressings are typically used for wounds that need to be kept dry. A stage I pressure ulcer benefits from a moist healing environment, which can be provided by a transparent dressing.
