Nursing Elites

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

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

Correct answer: B

Rationale: The presentation of low TSH and high free T4 levels is characteristic of hyperthyroidism, which is consistent with the symptoms of fatigue, weight gain, and constipation described in the case. In hyperthyroidism, the thyroid gland produces an excess of thyroid hormone leading to a hypermetabolic state, which can manifest with these symptoms.

2. The healthcare provider is assessing a client with Raynaud's phenomenon. Which finding should the healthcare provider expect?

• A. Thickened and hardened skin.
• B. Painless ulcers on the fingertips.
• C. Episodes of cyanosis and pallor in the fingers.
• D. Red, scaly patches on the hands.

Correct answer: C

Rationale: Raynaud's phenomenon is characterized by vasospasm, leading to episodes of cyanosis (bluish discoloration) and pallor (pale color) in the fingers or toes, often triggered by cold temperatures or stress. This occurs due to the reduced blood flow during vasospastic episodes, causing the discoloration. Choices A, B, and D are incorrect findings associated with other conditions and are not typical of Raynaud's phenomenon.

3. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory test should the nurse monitor to determine the effectiveness of the medication?

• A. Platelet count.
• B. Prothrombin time (PT) and international normalized ratio (INR).
• C. Activated partial thromboplastin time (aPTT).
• D. Fibrinogen level.

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of warfarin (Coumadin) therapy. These tests help assess the clotting time and the desired anticoagulant effect of the medication. Monitoring PT and INR levels is crucial to ensure that the client is within the therapeutic range, reducing the risk of bleeding or clotting complications associated with warfarin therapy. Platelet count (Choice A) measures the number of platelets in the blood and is not specific for monitoring warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice C) is more commonly used to monitor heparin therapy, not warfarin. Fibrinogen level (Choice D) assesses the amount of fibrinogen in the blood and is not a specific test for monitoring warfarin therapy.

4. What is the primary action of amlodipine when prescribed to a patient with hypertension?

• A. Increase heart rate
• B. Reduce blood pressure
• C. Lower cholesterol levels
• D. Decrease blood sugar levels

Correct answer: B

Rationale: Amlodipine is a calcium channel blocker that works by relaxing the blood vessels, leading to a reduction in blood pressure. This medication does not increase heart rate, lower cholesterol levels, or decrease blood sugar levels.

5. A 65-year-old woman presents with difficulty swallowing, weight loss, and a history of long-standing heartburn. She has been on proton-pump inhibitors for years, but her symptoms have worsened. What is the most likely diagnosis?

• A. Peptic stricture
• B. Esophageal cancer
• C. Achalasia
• D. Esophageal spasm

Correct answer: B

Rationale: The presentation of difficulty swallowing, weight loss, and worsening symptoms despite long-term use of proton-pump inhibitors raises suspicion for esophageal cancer, especially in a patient with a history of chronic heartburn. Esophageal cancer should be considered in this scenario due to the concerning symptoms and lack of improvement despite appropriate medical management.
