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 C

Explanation

Choice A rationale: Assessing the UOP is important, but not as urgent as correcting the potassium imbalance.

Choice B rationale: Obtaining a 12-lead ECG can help monitor the cardiac status, but it does not address the cause of the problem.

Choice C rationale: The PMHCP can order potassium replacement to prevent cardiac arrhythmias and other adverse effects of low potassium levels.

Choice D rationale: Stopping the regular insulin infusion can worsen the DKA and increase the risk of cerebral edema and coma.

A. An allergy to sulfa drugs. B. Cessation of smoking three years ago. C. Numbness in the soles of the feet. D. A history of obesity.

Correct Answer is A

Explanation

Choice A rationale: An allergy to sulfa drugs is important as some diabetes medications, like sulfonylureas, contain components related to sulfa drugs, which could cause an allergic reaction in susceptible individuals.

Choice B rationale: Smoking cessation and lifestyle history are important but might not directly impact initial diabetes treatment options.

Choice C rationale: Numbness in the soles of the feet might indicate neuropathy, a common complication of diabetes, but is not directly related to the choice of initial treatment.

Choice D rationale: While obesity is a risk factor for Type 2 diabetes, it's less critical for immediate treatment decisions compared to drug allergies that could impact medication choices.
