The patient presents with a complaint of "always dropping things and falling down." During the neurologic assessment, the nurse observes that the patient's display of rapid alternating movements is slow and misses often. The patient also loses balance during the Romberg Test. What neurologic problem would the nurse suspect?

Lesion of cranial nerve IX

Vestibular disease

Dysfunction of the cerebellum

Arteriovenous malformation (AVM) at frontal lobe

Answer and Explanation

The Correct Answer is C

A. A lesion of cranial nerve IX primarily affects swallowing and taste sensations rather than motor coordination or balance, so this is unlikely to explain the patient's symptoms.
B. Vestibular disease typically results in vertigo and balance issues, but the specific observations of slow alternating movements and loss of balance during the Romberg Test suggest a different underlying cause.
C. Dysfunction of the cerebellum would explain the patient's difficulties with rapid alternating movements and balance issues, as the cerebellum is responsible for coordinating motor activity and maintaining posture and balance. This aligns with the assessment findings, indicating a probable cerebellar dysfunction.
D. While an AVM in the frontal lobe could affect motor control, the specific symptoms presented, such as the inability to perform rapid movements and balance issues, are more characteristic of cerebellar dysfunction rather than a frontal lobe lesion.

Correct Answer is B

Explanation

A. Requesting antidepressant medication may be appropriate later, but it does not address the immediate need for emotional support and communication.
B. Encouraging the client to verbalize feelings about their diagnosis provides an opportunity for the client to express their concerns and emotions, fostering a therapeutic relationship and aiding in emotional processing.
C. While explaining improved prognosis can provide hope, it may minimize the client’s feelings of fear and uncertainty and could be perceived as dismissive.
D. Allowing time for reflection is important, but it should be balanced with the need for communication and support to prevent isolation.

Correct Answer is ["16"]

Explanation

To calculate the volume to be withdrawn from the vial, we need to follow these steps:

Convert the client's weight from pounds to kilograms:
- 110 lbs * (1 kg / 2.2 lbs) = 50 kg
Calculate the total dose of Vancomycin based on the prescribed dosage:
- 20 mg/kg * 50 kg = 1000 mg
Calculate the volume to be withdrawn from the vial:
- 1000 mg * (8 mL / 500 mg) = 16 mL
