The physician orders Ticar 800mg IM qoh.

The medication is supplied in 1g/2.5 mL. How many milliliters will the nurse administer? (SHADE SYRINGE #1 TO CORRECT DOSE & LABEL CORRECTLY TO RECEIVE CREDIT)

Choice A rationale

Graphesthesia is a sensory ability that allows an individual to recognize numbers or letters traced on their skin with their eyes closed. This assesses cortical sensory function, specifically the ability to interpret tactile stimuli, which is distinct from identifying a three-dimensional object by touch alone.

Choice B rationale

The Romberg test assesses proprioception and cerebellar function by asking the patient to stand with feet together and eyes closed. A positive Romberg sign indicates a loss of balance, suggesting a deficit in proprioception or vestibular function, and is not related to the identification of objects by touch.

Choice C rationale

Superficial reflexes, such as the plantar reflex or abdominal reflex, are elicited by light tactile stimulation of the skin and involve spinal cord reflex arcs. These reflexes assess the integrity of specific neurological pathways and are distinct from the cognitive process of identifying an object through tactile recognition.

Choice D rationale

Stereognosis is the ability to recognize familiar objects by touch and manipulation, without visual input. This cortical sensory function integrates tactile, proprioceptive, and kinesthetic sensations to form a mental image of the object's shape, size, and texture, allowing for its identification.

Choice A rationale

The charge nurse, by virtue of their leadership role and oversight of unit operations, is typically authorized to ensure patient safety and continuity of care. This includes re-verifying and administering medications in urgent situations when the preparing nurse is unavailable, adhering to established protocols and double-checking the medication before administration to prevent errors.

Choice B rationale

Limiting medication administration solely to the preparing nurse could delay critical treatment, especially during emergencies. While optimal, this practice is superseded by the need for timely patient care and adherence to a "second nurse check" policy, which enhances safety by having an additional qualified professional verify the medication.

Choice C rationale

Any licensed Registered Nurse (RN) or Licensed Practical Nurse (LPN) on the unit, if familiar with the patient and their condition, possesses the scope of practice and clinical competency to administer medications. This ensures patient safety through appropriate verification, patient identification, and adherence to the "rights" of medication administration, maintaining continuity of care.

Choice D rationale

Pharmacy technicians are not licensed healthcare professionals authorized to administer medications directly to patients. Their scope of practice is limited to preparing, packaging, and distributing medications under the supervision of a licensed pharmacist, lacking the clinical assessment and administration privileges of nursing staff.
