A patient arrives in the emergency department exhibiting symptoms of a cerebrovascular accident (CVA). Which diagnostic evaluations would the nurse anticipate before treatment is initiated?

Prothrombin level

Brain CT or MRI

Chest x-ray

Lumbar puncture

Answer and Explanation

The Correct Answer is B

Choice A rationale

While prothrombin level is an important test in evaluating blood clotting disorders, it is not typically used in the initial diagnostic evaluations for a cerebrovascular accident (CVA) or stroke.
Choice B rationale
Brain CT or MRI scans are commonly used in the initial diagnostic evaluations for a CVA. These imaging tests can show bleeding in the brain, an ischemic stroke, a tumor, or other conditions.
Choice C rationale
A chest x-ray is not typically used in the initial diagnostic evaluations for a CVA. It is more commonly used to diagnose conditions affecting the lungs and heart.
Choice D rationale
A lumbar puncture, or spinal tap, may be used in some cases to help diagnose a CVA, but it is not typically part of the initial diagnostic evaluations.

Correct Answer is ["0.9 "]

Explanation

Step 1: We are instructed to administer tobramycin 35mg IM every 8 hours. The available supply is 40mg in a 1 mL vial.

Step 2: We need to find out how many mL’s should the nurse administer. Step 3: We can set up a proportion to solve this.

Step 4: If 40mg is equivalent to 1mL, then 35mg is equivalent to x mL. Step 5: Solving for x gives us x = (35mg ÷ 40mg) × 1mL.

Step 6: Calculating the above expression gives us x = 0.875 mL.

Step 7: Rounding our answer to the nearest tenth, we get 0.9 mL. So, the nurse should administer 0.9 mL.

A. Follow up by having the client perform the Rinne test B. Reposition the client supine to ensure safety. C. Document successful completion of the assessment. D. Facilitate a referral to a neurologist.

Correct Answer is C

Explanation

Choice A rationale
The Rinne test is a hearing test used to evaluate the difference between sound transmission through air conduction versus bone conduction. It is not typically used following a Romberg test, which evaluates balance.
Choice B rationale
While ensuring the patient’s safety is always important, repositioning the client supine is not the typical response to slight swaying during a Romberg test.
Choice C rationale
Slight swaying during a Romberg test is considered normal. Therefore, documenting successful completion of the assessment would be the appropriate action.
Choice D rationale
A referral to a neurologist is not typically necessary for slight swaying during a Romberg test, as this is considered within normal limits.
