Question 1
Which condition is commonly associated with underproduction of adrenocortical hormones?
Correct Answer:
Addison's disease
Explanation:
Underproduction of adrenocortical hormones means the adrenal cortex isn’t making enough cortisol and aldosterone, leading to adrenal insufficiency. Addison’s disease is the classic example of primary adrenal insufficiency, usually from autoimmune destruction of the adrenal cortex, causing low cortisol and low aldosterone. This results in symptoms like fatigue, weakness, weight loss, abdominal pain, low blood pressure, and salt cravings. Because aldosterone is low, there’s impaired sodium reabsorption and potassium excretion, which can lead to hyponatremia and hyperkalemia. The lack of cortisol also contributes to hypoglycemia and poor stress response. Hyperpigmentation can occur due to increased ACTH stimulating melanocytes. Lab patterns support the diagnosis: cortisol is low, and ACTH is elevated because the pituitary is trying to stimulate the adrenals. Mineralocorticoid deficiency adds to volume depletion and electrolyte abnormalities. Treatment involves replacing glucocorticoids (like hydrocortisone) and, if needed, mineralocorticoids (like fludrocortisone), along with education on stress dosing during illness or surgery. Other options don’t fit because they involve excess cortisol (Cushing’s), thyroid overactivity (hyperthyroidism), or an autoimmune gland condition unrelated to the adrenal cortex (Sjögren’s).
Question 2
Which instruction is appropriate when taking alendronate to prevent osteoporosis complications?
Correct Answer:
Take the medication with a full glass of water and sit upright for 30 minutes.
Explanation:
Taking alendronate correctly hinges on how the drug travels through the esophagus into the stomach. It should be taken with a full glass of water while you remain upright for at least 30 minutes before consuming anything else. This positioning and timing help ensure the medication reaches the stomach promptly and minimizes irritation to the esophagus, which can occur if the pill lingers in the esophagus. The other options don’t fit because lying down soon after taking the pill increases esophageal exposure and potential irritation; taking it with an antacid can bind the medication and reduce its absorption, making it less effective; and taking it immediately before breakfast often fails to maintain the required 30-minute interval before eating, which can also compromise absorption and safety.
Question 3
After unilateral adrenalectomy for Cushing's disease, which discharge instruction is most appropriate?
Correct Answer:
Explain the signs and symptoms of infection and when to call the health-care provider.
Explanation:
After adrenal surgery, the body's healing process and immune defenses are temporarily vulnerable, making infection a critical safety concern. Teaching the patient to recognize signs of infection and know when to contact the health-care provider helps catch problems early and prevent complications like wound infection or sepsis. Helpful examples to understand include fever or chills, increasing redness, swelling, warmth, or drainage at the incision, foul-smelling wound drainage, or the patient feeling unusually weak or dizzy. If any of these symptoms appear, timely medical evaluation is essential. While other aspects of care—such as whether to take steroid medications, concerns about sexual function and hormone replacement, or respiratory exercises—may be relevant in certain cases, they do not address the most immediate safety need for discharge after this surgery. The priority is ensuring the patient can monitor for infection and seek prompt help if needed.
Question 4
When monitoring a patient on corticosteroids, which adverse effect is most commonly observed?
Correct Answer:
Hyperglycemia
Explanation:
Corticosteroids disrupt glucose metabolism by increasing hepatic glucose production and causing insulin resistance, which most commonly raises blood sugar levels. This metabolic effect is the hallmark systemic adverse effect of glucocorticoid therapy and can occur quickly, becoming more pronounced with higher doses or longer use. That’s why hyperglycemia is the best answer here. Other listed effects can occur in some patients—fragile skin with long-term or high-dose exposure, nervousness from mood changes, and hypotension is not typical ( steroids tend to cause fluid retention and sometimes hypertension)—but they are less consistently tied to the everyday metabolic impact of corticosteroids. In practice, closely monitor blood glucose and adjust management as needed.
Question 5
What drug class is used preoperatively to prevent catecholamine surge during pheochromocytoma surgery?
Correct Answer:
Alpha-adrenergic blocker
Explanation:
During pheochromocytoma surgery, manipulation of the tumor can release large amounts of catecholamines, causing dangerous spikes in blood pressure. The best way to prevent this surge is by blocking alpha-adrenergic receptors, especially the alpha-1 receptors on blood vessels. When these receptors are blocked, catecholamine-induced vasoconstriction is markedly reduced, so blood pressure stays more stable during tumor handling. This alpha blockade is typically started days to weeks before surgery to allow the vessels to relax and for blood volume to normalize, because chronic catecholamine excess often leaves the circulating volume relatively low. After adequate alpha blockade, a beta blocker may be added if there’s still tachycardia or arrhythmia, but only once alpha blockade is in place. Using a beta blocker alone would let unopposed alpha activity raise blood pressure during the procedure, which is dangerous. ACE inhibitors or calcium channel blockers don’t address the acute catecholamine surge as effectively as alpha blockade and aren’t the primary preventive strategy in this setting.

About this Exam

The NCLEX Adrenal Disorders Practice Exam is a comprehensive study resource specifically designed for nursing students and graduates preparing for the National Council Licensure Examination (NCLEX-RN or NCLEX-PN). This targeted practice test focuses exclusively on adrenal gland dysfunction, a critical and often challenging area of endocrine system nursing. It is designed to evaluate and enhance the examinee's knowledge and critical thinking skills related to assessment, diagnosis, planning, implementation, and evaluation of patient care for various adrenal disorders, including hyperfunction (Cushing's syndrome, Conn's syndrome) and hypofunction (Addison's disease, acute adrenal crisis).

 What to Expect in the Final Exam

While the NCLEX uses adaptive testing with various question types, this dedicated practice test provides a structured simulation to focus your review. The final assessment within this study program is a simulated 100-question exam that mirrors the style, difficulty, and format of actual NCLEX questions related to adrenal disorders. You can expect multiple-choice questions, select-all-that-apply (SATA), drag-and-drop sequencing, and other alternate formats. The passing score for this practice final is set at 75-80%, serving as a benchmark of proficiency and readiness for the actual licensure exam. You are typically allowed 3 hours to complete the simulated final to mimic the time pressure of the NCLEX.
