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.

Choice A rationale
The best way to determine if a patient can safely and effectively self-administer medications is to ask the patient to demonstrate the instillation of the medications. This allows the nurse to directly observe the patient’s technique, identify any errors, and provide immediate feedback and instruction. It also gives the patient an opportunity to ask questions and clarify any misunderstandings. This method is often referred to as the “show-back” or “teach-back” method and is widely used in patient education to confirm understanding and competency.
Choice B rationale
While assessing the patient for any previous inability to self-manage medications can provide useful information, it does not directly assess the patient’s ability to self-administer the new eye medications. Previous difficulties may be due to factors that do not apply to the current situation, such as complex medication regimens, cognitive impairment, or lack of resources.
Choice C rationale
Although the patient accurately describing the directions for administering the medications indicates that the patient understands the instructions, it does not necessarily mean that the patient can perform the task correctly. Physical limitations, dexterity issues, or misunderstanding of the instructions can still result in incorrect administration.
Choice D rationale

Assessing the patient’s functional status can provide valuable information about the patient’s overall ability to perform activities of daily living, including medication management.
However, it does not specifically assess the patient’s ability to self-administer eye medications.

Choice A rationale
Instructing the client on daily muscle stretching can help alleviate and relax muscle spasms, which is beneficial for a client diagnosed with multiple sclerosis.

Choice B rationale
Ordering a low-residual diet is not typically a part of the care plan for a client diagnosed with multiple sclerosis.
Choice C rationale
Encouraging the client to void every hour may not be necessary for a client diagnosed with multiple sclerosis, unless there are specific urinary symptoms present.
Choice D rationale
Providing total assistance with all activities of daily living may not be necessary for a client diagnosed with multiple sclerosis, as the level of assistance required can vary greatly depending on the severity of the disease.
