Nursing Elites

1. In a 45-year-old woman with a history of arthritis experiencing severe heartburn and indigestion refractory to antacids, which findings on an esophageal manometry study are consistent with her diagnosis?

• A. Vigorous peristalsis and elevated lower esophageal sphincter (LES) pressure
• B. Absent peristalsis and elevated LES pressure
• C. Absent peristalsis and decreased LES pressure
• D. Vigorous peristalsis and decreased LES pressure

Correct answer: C

Rationale: The correct answer is C: Absent peristalsis and decreased lower esophageal sphincter (LES) pressure. The patient in this scenario has scleroderma esophagus, characterized by atrophy of esophageal smooth muscle, leading to the loss of peristalsis and LES tone. These changes contribute to severe symptoms of gastroesophageal reflux disease (GERD) and esophagitis. Absent peristalsis and decreased LES pressure are typical findings in scleroderma esophagus, contributing to the refractory nature of the patient's symptoms despite antacid use.

2. A patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?

• A. Complete blood count (CBC)
• B. Prothrombin time (PT)/INR
• C. Partial thromboplastin time (PTT)
• D. Serum potassium level

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.

3. The healthcare provider is caring for a client with a chest tube. Which assessment finding requires immediate intervention?

• A. Intermittent bubbling in the water seal chamber.
• B. Drainage of 75 ml in the first hour post-insertion.
• C. Crepitus around the insertion site.
• D. Fluctuation of the water level in the water seal chamber with respiration.

Correct answer: C

Rationale: Crepitus (subcutaneous emphysema) around the insertion site can indicate air leakage, requiring immediate intervention to prevent complications such as pneumothorax. This assessment finding suggests that there may be a break in the chest tube system, leading to air entering the pleural space. Prompt intervention is crucial to prevent respiratory compromise and further complications.

4. Why is a client with ascites scheduled for a paracentesis procedure?

• A. To diagnose liver disease
• B. To relieve abdominal pressure
• C. To assess kidney function
• D. To reduce blood pressure

Correct answer: B

Rationale: The correct answer is B: "To relieve abdominal pressure." Paracentesis is performed to drain accumulated fluid in the peritoneal cavity, providing symptomatic relief for clients with ascites. Choice A is incorrect because paracentesis is not a diagnostic procedure for liver disease. Choice C is incorrect as assessing kidney function would typically involve different procedures. Choice D is incorrect as paracentesis does not directly impact blood pressure.

5. A 28-year-old woman presents with abdominal pain, bloating, and diarrhea. She notes that her symptoms improve with fasting. She has a history of iron deficiency anemia. What is the most likely diagnosis?

• A. Irritable bowel syndrome
• B. Celiac disease
• C. Lactose intolerance
• D. Crohn's disease

Correct answer: B

Rationale: The symptoms of abdominal pain, bloating, diarrhea improving with fasting, and a history of iron deficiency anemia are characteristic of celiac disease. Celiac disease is an autoimmune disorder triggered by gluten consumption, leading to damage in the small intestine. The improvement with fasting may be due to the temporary avoidance of gluten-containing foods. Irritable bowel syndrome, lactose intolerance, and Crohn's disease do not typically present with improvement of symptoms with fasting or have a clear association with iron deficiency anemia.
