A nurse is admitting a client who is experiencing an Addisonian crisis. Which of the following should the nurse anticipate an order for?

IV hydrocortisone

Ketoconazole and insulin

Lactated Ringer's IV infusion

Furosemide slow IV push

Answer and Explanation

The Correct Answer is A

A. IV hydrocortisone: In an Addisonian crisis, there is an acute adrenal insufficiency which requires immediate treatment with IV hydrocortisone to replace the deficient glucocorticoids. This helps to rapidly correct the hormone imbalance and stabilize the patient.
B. Ketoconazole and insulin: Ketoconazole is an antifungal medication used to treat Cushing syndrome, not Addisonian crisis. Insulin is used for managing blood glucose levels and is not directly related to the treatment of an Addisonian crisis.
C. Lactated Ringer's IV infusion: While fluid replacement may be necessary in an Addisonian crisis, the immediate priority is to address the adrenal insufficiency with hydrocortisone. Lactated Ringer's may be used to support fluid balance but is not a substitute for glucocorticoid therapy.
D. Furosemide slow IV push: Furosemide is a diuretic used to manage fluid retention and is not indicated for treating Addisonian crisis. The primary treatment for Addisonian crisis is to address the adrenal hormone deficiency with hydrocortisone.

Correct Answer is B

Explanation

A. Radioactive iodine uptake test: This test is used to assess thyroid function and diagnose thyroid disorders, such as hyperthyroidism. It is not used to diagnose Cushing syndrome.
B. 24-hour cortisol urine study: This test measures cortisol levels in the urine over a 24-hour period and is commonly used to diagnose Cushing syndrome by evaluating elevated cortisol production.
C. Adrenocorticotropic hormone (ACTH) stimulation test: This test evaluates adrenal function and is typically used to assess adrenal insufficiency rather than Cushing syndrome.
D. Edrophonium (Tensilon) test: This test is used to diagnose myasthenia gravis, not Cushing syndrome. It evaluates the effect of the medication on muscle strength.

A. Acetaminophen B. Furosemide C. Ketoconazole D. Levothyroxine

Correct Answer is C

Explanation

A. Acetaminophen: While acetaminophen can help manage fever, it is not a primary treatment for acute thyrotoxicosis. The management of acute thyrotoxicosis involves addressing the overproduction of thyroid hormones, not just symptom relief.
B. Furosemide: Furosemide is a diuretic used for fluid retention and hypertension, not for managing thyrotoxicosis. It does not address the underlying cause of acute thyrotoxicosis.
C. Ketoconazole: Ketoconazole is an anti-fungal medication that also has the effect of inhibiting cortisol synthesis and can be used to treat acute thyrotoxicosis by reducing the production of thyroid hormones. It is used as part of a broader treatment plan.
D. Levothyroxine: Levothyroxine is used to treat hypothyroidism by providing synthetic thyroid hormone. It is not used to treat thyrotoxicosis, which involves excessive thyroid hormone levels, not deficiency.
