Nursing Elites

1. A 45-year-old woman presents with fatigue, weight gain, and constipation. Laboratory tests reveal high TSH and low free T4 levels. What is the most likely diagnosis?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Thyroiditis
• D. Thyroid cancer

Correct answer: A

Rationale: The combination of high TSH and low free T4 levels is consistent with hypothyroidism, which matches the patient's symptoms of fatigue, weight gain, and constipation. In hypothyroidism, the thyroid gland does not produce enough thyroid hormones, leading to a decrease in metabolic rate and resulting in these clinical findings.

2. The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.

3. 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.

4. The client with bacterial pneumonia is receiving intravenous antibiotics. Which assessment finding indicates that the treatment is effective?

• A. Increased respiratory rate.
• B. Decreased oxygen saturation.
• C. Clear lung sounds.
• D. Elevated white blood cell count.

Correct answer: C

Rationale: Clear lung sounds indicate that the antibiotics are effectively treating the bacterial pneumonia by resolving the infection and reducing the inflammation in the lungs, leading to improved air exchange and ventilation. Increased respiratory rate (Choice A) and decreased oxygen saturation (Choice B) are indicative of ongoing respiratory distress and ineffective treatment. Elevated white blood cell count (Choice D) suggests a persistent infection rather than effective treatment.

5. A 35-year-old male patient presents with right upper quadrant pain, fever for the past 48 hours, preceded by new onset jaundice over the past few weeks. He states that he has had diarrhea on and off for several years but never had this investigated. A liver ultrasound is negative for gallstones or evidence of cholecystitis. His lab tests reveal total bilirubin 6.2, alkaline phosphatase 450, AST 150, ALT 120, albumin 2.6. The next diagnostic test of choice would be

• A. Liver biopsy
• B. Magnetic resonance cholangiopancreatography
• C. Hepatitis B surface antigen and hepatitis C RNA assay
• D. Colonoscopy with biopsies

Correct answer: B

Rationale: The patient's presentation with right upper quadrant pain, fever, and jaundice, along with abnormal liver function tests, suggests a biliary tract problem. Given the suspicion of obstructed bile flow and the negative liver ultrasound for gallstones, magnetic resonance cholangiopancreatography (MRCP) is the next appropriate step to evaluate the biliary system and pancreatic ducts. MRCP is non-invasive and can provide detailed images for diagnosis. Liver biopsy is not the preferred initial diagnostic test in this context. Testing for hepatitis B and C would not address the current clinical scenario, and colonoscopy is not indicated for the presenting symptoms.
