A patient presents to the ER with numbness in the left arm, a severe headache, and trouble speaking. Which of the following diagnostic tests do you anticipate the healthcare provider to order?

CT scan

Hemoglobin and hematocrit

MRI

Pulmonary angiography

Answer and Explanation

The Correct Answer is A

Choice A reason: CT scan rapidly detects ischemic stroke or hemorrhage in the brain, critical for numbness, headache, and speech issues, guiding urgent treatment decisions.

Choice B reason: Hemoglobin and hematocrit assess blood count, not brain pathology like stroke, which requires imaging to identify infarction or bleeding, not anemia.

Choice C reason: MRI offers detailed stroke imaging but is slower than CT, less ideal for acute ER settings needing immediate diagnosis of neurological symptoms.

Choice D reason: Pulmonary angiography evaluates lung vessels for embolism, irrelevant to stroke symptoms (numbness, headache, speech difficulty), which localize to brain issues.

Correct Answer is D

Explanation

Choice A reason: Levothyroxine takes weeks to normalize metabolism in hypothyroidism as T4 converts to T3 gradually, so immediate symptom relief isn’t accurate or expected.

Choice B reason: Levothyroxine supplements, not decreases, thyroxine in hypothyroidism. Decreasing overproduction applies to hyperthyroidism treatments like antithyroid drugs, not this condition.

Choice C reason: Hypothyroidism requires lifelong levothyroxine since the thyroid can’t produce hormone. Stopping when symptoms resolve risks recurrence, making this advice incorrect.

Choice D reason: Excess levothyroxine mimics hyperthyroidism, causing tremors, nervousness, and insomnia from overstimulated metabolism, correctly indicating a need for dose adjustment.

A. Teaching the parents to establish a diet that promotes optimal growth B. Preventing celiac crisis and resulting problems C. Helping the parents and child adjust to the long-term dietary restrictions D. Minimizing the complications of respiratory involvement E. Peaches

Correct Answer is A

Explanation

Choice A reason: Celiac disease requires a gluten-free diet to prevent malabsorption, ensuring nutrient uptake for growth, the priority in a child to support development long-term.

Choice B reason: Celiac crisis, severe diarrhea, is rare post-diagnosis with dietary control; preventing it is secondary to establishing a sustainable diet for ongoing health.

Choice C reason: Adjusting to dietary restrictions supports compliance but follows initial education on a gluten-free diet, which is foundational for managing celiac disease effectively.

Choice D reason: Respiratory issues aren’t linked to celiac disease, which affects the gut; this option is irrelevant, as complications are gastrointestinal, not pulmonary.
