A client with diffuse axonal injury is experiencing difficulty with respiration, heart rate, blood pressure. Which region of the brain does the nurse suspect to be affected?

Cerebral motor cortex

Brain stem

Broca's area

Occipital lobe

Answer and Explanation

The Correct Answer is B

Choice A rationale: Cerebral motor cortex primarily controls voluntary movements, not autonomic functions like respiration, heart rate, and blood pressure.
Choice B rationale: The brain stem controls vital functions like respiration, heart rate, and blood pressure, so damage to this area can lead to difficulties in these functions.
Choice C rationale: Broca's area is responsible for speech production and is not directly involved in autonomic functions.
Choice D rationale: The occipital lobe is primarily associated with visual processing and perception, not autonomic functions like respiration or heart rate.

Correct Answer is B

Explanation

Choice A rationale: Elevated T3 and T4 with low TSH levels are indicative of hyperthyroidism, not a side effect of radioactive iodine treatment.

Choice B rationale: One of the expected side effects of RAI treatment for hyperthyroidism is permanent hypothyroidism (or underactive thyroid, when the thyroid does not produce enough hormones). Elevated TSH levels with low T3 and T4 are indicative of hypothyroidism.

Choice C rationale: Low TSH, T3, and T4 levels are not typical outcomes of radioactive iodine treatment; typically, the treatment leads to a decrease in T3 and T4 with increased TSH levels.

Choice D rationale: Elevated TSH and low T3 is major side effect of radioactive iodine treatment for hyperthyroidism. However, it does not cause elevated T4 levels.

A. intubation and mechanical ventilation. B. IV infusion of (Sandoglobulin). C. administration of methylprednisolone (Solu-Medrol). D. insertion of a nasogastric (NG) feeding tube

Correct Answer is B

Explanation

Choice A rationale: Intubation and mechanical ventilation may be needed if the respiratory muscles are affected by GBS, but this is not a routine intervention at this stage.

Choice B rationale: One of the main treatments of GBS is IV immunoglobulin therapy (IVIG), which involves infusing antibodies from donated blood plasma to block the harmful immune response that damages the nerves. Sandoglobulin is one of the brand names of IVIG used for GBS. IVIG can help shorten the duration and severity of the disease, and improve the recovery rate.

Choice C rationale: Methylprednisolone is a corticosteroid that can reduce inflammation, but it is not recommended for GBS, as it may worsen the condition or increase the risk of infection.

Choice D rationale: NG feeding tube may be required if the patient has difficulty swallowing, but this is also not a standard intervention at this time.
