Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). Which instruction should the nurse provide?

• A. Avoid green leafy vegetables.
• B. Take aspirin for headaches.
• C. Use a soft-bristled toothbrush.
• D. Limit fluid intake to 1 liter per day.

Correct answer: C

Rationale: The correct instruction for a client on warfarin therapy, especially with a history of DVT, is to use a soft-bristled toothbrush. This is crucial to prevent gum bleeding, which is a risk due to the anticoagulant effects of warfarin. Green leafy vegetables are rich in vitamin K, which can interfere with warfarin's effectiveness, so they should be consumed consistently to maintain a balance. Aspirin is not recommended for headaches in clients on warfarin due to the increased risk of bleeding. Limiting fluid intake is not a standard instruction for clients on warfarin therapy.

2. A 30-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 clinical presentation of a 30-year-old woman with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria is highly suggestive of type 1 diabetes mellitus. Type 1 diabetes mellitus is characterized by autoimmune destruction of pancreatic beta cells, leading to insulin deficiency and subsequent hyperglycemia. The presence of ketonuria indicates the breakdown of fats for energy due to the lack of insulin. In contrast, type 2 diabetes mellitus typically presents with gradual onset and is often associated with insulin resistance rather than absolute insulin deficiency. Diabetes insipidus is characterized by polyuria and polydipsia but is not associated with hyperglycemia or ketonuria. Hyperthyroidism may present with symptoms like fatigue but does not typically cause hyperglycemia or ketonuria.

3. A client with a cold is taking the antitussive benzonatate (Tessalon). Which assessment data indicates to the nurse that the medication is effective?

• A. Reports reduced nasal discharge.
• B. Denies having coughing spells.
• C. Able to sleep through the night.
• D. Expectorating bronchial secretions.

Correct answer: B

Rationale: The correct answer is B. Denying having coughing spells indicates the effectiveness of benzonatate, an antitussive that suppresses coughing. The goal of antitussive medications like benzonatate is to reduce or eliminate coughing, so the absence of coughing spells signifies the drug's efficacy. The other options do not directly reflect the medication's intended effect and are not specific indicators of benzonatate's effectiveness.

4. A patient with chronic pain is prescribed gabapentin. What is the primary purpose of this medication?

• A. Relieve neuropathic pain
• B. Reduce inflammation
• C. Enhance opioid analgesia
• D. Suppress cough

Correct answer: A

Rationale: Gabapentin is primarily prescribed to relieve neuropathic pain. It works by stabilizing electrical activity in the nerves, making it effective in managing conditions such as diabetic neuropathy, postherpetic neuralgia, and other forms of chronic pain originating from nerve damage.

5. A 65-year-old white female with a history of arthritis, congestive heart failure, and osteoporosis complains of odynophagia for two weeks. A barium swallow shows a moderate-sized crater just above the gastroesophageal junction. What is the least likely contributor to this condition?

• A. NSAIDs
• B. Alendronate
• C. Iron sulfate
• D. Calcium channel blocker

Correct answer: D

Rationale: In this case, the least likely contributor to the condition described is the calcium channel blocker. NSAIDs, alendronate, and iron sulfate have been associated with pill-induced esophagitis, which can present with symptoms like odynophagia and erosions or ulcers on imaging studies. Pill-induced esophagitis is often due to factors like inadequate water intake with the medication, being in a supine position, or underlying motility disorders. Discontinuation of the offending medication typically leads to rapid resolution of esophageal injury. Acid-suppressive therapy may be used to prevent reflux-related damage.
