Nursing Elites

1. A patient is admitted with a diagnosis of myasthenia gravis. What symptom should the nurse expect to find during the assessment?

• A. Joint pain
• B. Muscle weakness
• C. Loss of sensation
• D. Severe headache

Correct answer: B

Rationale: Myasthenia gravis is a neuromuscular disorder characterized by muscle weakness and fatigue, especially in the voluntary muscles. Patients with myasthenia gravis commonly experience weakness in muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. This weakness typically worsens with activity and improves with rest. Joint pain, loss of sensation, and severe headaches are not typical symptoms of myasthenia gravis. Therefore, the correct answer is muscle weakness (choice B) as it aligns with the characteristic symptom of myasthenia gravis.

2. The client has received 250 ml of 0.9% normal saline through the IV line in the last hour. The client is now tachypneic and has a pulse rate of 120 beats/minute, with a pulse volume of +4. In addition to reporting the assessment findings to the healthcare provider, what action should the nurse implement?

• A. Discontinue the IV and apply pressure at the site.
• B. Decrease the saline to a keep-open rate.
• C. Increase the rate of the current IV solution.
• D. Change the IV fluid to 0.45% normal saline at the same rate.

Correct answer: B

Rationale: In this scenario, the client is showing signs of fluid overload with tachypnea and a high pulse rate. Decreasing the saline to a keep-open rate is appropriate to prevent further fluid volume excess. This action allows for IV access to be maintained while reducing the fluid administered, helping to manage the symptoms of fluid overload.

3. 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.

4. A client with acute pancreatitis is admitted to the hospital. What is the priority nursing intervention for this client?

• A. Administering oral pancreatic enzymes
• B. Encouraging a high-protein diet
• C. Maintaining NPO status and administering IV fluids
• D. Providing a low-fat diet

Correct answer: C

Rationale: The priority nursing intervention for a client with acute pancreatitis is to maintain NPO (nothing by mouth) status and administer IV fluids. This approach helps rest the pancreas, decrease pancreatic stimulation, and prevent further exacerbation of the condition. By withholding oral intake and providing IV fluids, the pancreas is given the opportunity to recover and inflammation can be reduced. This intervention is crucial in the acute phase of pancreatitis to support the healing process and prevent complications.

5. A 35-year-old man presents with difficulty swallowing, weight loss, and regurgitation of undigested food. A barium swallow shows a 'bird beak' appearance of the lower esophagus. What is the most likely diagnosis?

• A. Esophageal cancer
• B. Achalasia
• C. Peptic stricture
• D. Gastroesophageal reflux disease

Correct answer: B

Rationale: The 'bird beak' appearance on a barium swallow is characteristic of achalasia, a condition where the lower esophageal sphincter fails to relax properly. This leads to difficulty swallowing, weight loss, and regurgitation of undigested food, which are hallmark symptoms of achalasia.
