Nursing Elites

1. A 40-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The combination of symptoms including fatigue, polyuria, polydipsia, along with laboratory findings of hyperglycemia and ketonuria strongly suggest type 1 diabetes mellitus. In type 1 diabetes mellitus, there is a deficiency of insulin leading to high blood sugar levels (hyperglycemia) and the breakdown of fats producing ketones, causing ketonuria. Type 2 diabetes mellitus typically presents differently and is more common in older individuals. Diabetes insipidus is characterized by excessive thirst and urination due to a deficiency of antidiuretic hormone, distinct from the provided clinical scenario. Hyperthyroidism may present with some overlapping symptoms like fatigue, but it does not account for the specific laboratory findings of hyperglycemia and ketonuria seen in this case.

2. A 28-year-old woman presents with abdominal pain, diarrhea, and rectal bleeding. She has a history of similar episodes in the past. What is the most likely diagnosis?

• A. Ulcerative colitis
• B. Irritable bowel syndrome
• C. Celiac disease
• D. Diverticulitis

Correct answer: A

Rationale: The constellation of symptoms including abdominal pain, diarrhea, and rectal bleeding in a young woman with a history of similar episodes is highly suggestive of ulcerative colitis. This chronic inflammatory condition primarily affects the colon and rectum, leading to symptoms such as bloody diarrhea, abdominal pain, and urgency. The recurrent nature of her symptoms and the presence of rectal bleeding further support this diagnosis over other conditions listed, such as irritable bowel syndrome, celiac disease, or diverticulitis, which typically do not present with the same combination of symptoms and history.

3. The healthcare provider is caring for a client with Guillain-Barré syndrome. Which assessment finding requires the healthcare provider's immediate action?

• A. Loss of deep tendon reflexes.
• B. Ascending weakness.
• C. New onset of confusion.
• D. Decreased vital capacity.

Correct answer: D

Rationale: Decreased vital capacity is the most critical assessment finding in a client with Guillain-Barré syndrome as it indicates respiratory compromise. This requires immediate intervention to ensure adequate ventilation and prevent respiratory failure, a common complication of this syndrome. Monitoring and maintaining respiratory function are vital in these clients to prevent complications such as respiratory distress, hypoxia, and respiratory failure. Loss of deep tendon reflexes and ascending weakness are typical manifestations of Guillain-Barré syndrome but do not require immediate action compared to compromised respiratory function. New onset of confusion may be a concern but is not as immediately life-threatening as decreased vital capacity.

4. A 35-year-old man presents with fatigue, weight loss, and hyperpigmentation of the skin. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

• A. Cushing's syndrome
• B. Addison's disease
• C. Hypothyroidism
• D. Pheochromocytoma

Correct answer: B

Rationale: The clinical presentation of a 35-year-old man with fatigue, weight loss, hyperpigmentation of the skin, hyponatremia, hyperkalemia, and low cortisol levels is classic for Addison's disease. These findings are consistent with primary adrenal insufficiency, where the adrenal glands fail to produce adequate cortisol. In Addison's disease, the adrenal cortex is damaged, leading to decreased cortisol production and elevated levels of ACTH. This results in symptoms such as fatigue, weight loss, and hyperpigmentation due to increased ACTH production stimulating melanocytes. Hyponatremia and hyperkalemia are common electrolyte abnormalities seen in Addison's disease due to aldosterone deficiency. Therefore, the correct diagnosis in this case is Addison's disease.

5. A client with a history of myocardial infarction (MI) is prescribed nitroglycerin (Nitrostat) for chest pain. Which instruction should the nurse provide?

• A. Take the medication with food.
• B. Swallow the tablet whole.
• C. Take the medication at bedtime.
• D. Place the tablet under your tongue.

Correct answer: D

Rationale: The correct instruction for a client prescribed nitroglycerin (Nitrostat) for chest pain is to place the tablet under the tongue. This route allows for rapid absorption of the medication, providing quick relief for chest pain associated with myocardial infarction.
