A patient is complaining of a sharp pain along the costovertebral angles (CVA) during percussion.
The nurse knows that this symptom most often indicates:

Choice A rationale

Documenting the error and notifying the supervisor are necessary steps, but they are not the most immediate or comprehensive actions. The priority in a medication error is patient safety, which requires immediate medical assessment and intervention. This step follows after direct patient care and notification of the physician.

Choice B rationale

Administering the original drug and observing for adverse reactions addresses part of the problem, but it does not prioritize immediate medical consultation regarding the mistakenly administered drug. The focus should be on the potential effects of the incorrect medication and timely intervention to mitigate harm.

Choice C rationale

The most appropriate and immediate action is to call the physician to inform them of the medication error. This allows the physician to assess the potential harm to the patient based on the specific drug, dosage, and patient's condition, and to order appropriate interventions. An incident report is crucial for organizational learning and quality improvement.

Choice D rationale

Deciding not to act based on a quick check of allergies or contraindications is highly negligent and unsafe. Even if there are no apparent immediate contraindications, any medication error carries inherent risks and requires a thorough medical evaluation by the physician. This approach prioritizes patient safety over documentation and investigation.

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.
