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.)

Choice A rationale
Applying the pulse oximeter probe to the toe might not provide an accurate reading if the client has poor peripheral circulation. Additionally, thickened toenails can interfere with the reading.
Choice B rationale

Edema in the hands can affect the accuracy of a pulse oximeter reading. The probe might not fit properly or provide a reliable reading if the finger is swollen.
Choice C rationale
Applying the pulse oximeter probe to a skin fold is not recommended. The probe needs to be placed on a relatively flat, thin area of skin to accurately measure oxygen saturation.
Choice D rationale
The earlobe is a suitable alternative site for pulse oximetry if the fingers and toes are not viable options. The earlobe is typically less affected by peripheral vasoconstriction, which can occur with hypothermia, certain medications, and certain diseases. Therefore, Choice D is the correct answer.

Choice A rationale

The statement “The client should first move the strong leg then the weak one” is not the best practice when using a cane. The client should move the cane and the weak leg forward at the same time, then move the strong leg.
Choice B rationale
The statement “When the client moves, he should move the cane forward first” is the correct practice. Moving the cane first provides stability and support for the next step.
Choice C rationale
The statement “The client should hold the cane on the weak side of his body” is not the correct practice. The cane should be held on the strong side of the body to provide support for the weak side.
Choice D rationale
The statement “The grip should be level with the client’s waist” is a good practice, but it’s not the best answer for this question. The grip of the cane should be at the level of the client’s wrist when the client’s arm is hanging down. This allows the client to maintain a slight bend in their elbow when holding the cane.
