Nursing Elites

1. Why is a low-protein diet recommended for a patient with renal failure?

• A. To prevent fluid overload
• B. To reduce nitrogenous waste
• C. To maintain electrolyte balance
• D. To prevent hyperglycemia

Correct answer: B

Rationale: A low-protein diet is crucial for patients with renal failure to reduce the generation of nitrogenous waste products like urea and creatinine, which the compromised kidneys struggle to eliminate effectively. By limiting protein intake, the production of these waste products is decreased, lessening the burden on the kidneys and helping to manage the progression of renal failure. Choices A, C, and D are incorrect because a low-protein diet primarily aims to reduce the workload on the kidneys by decreasing the production of nitrogenous waste, not to prevent fluid overload, maintain electrolyte balance, or prevent hyperglycemia.

2. 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.

3. A client is being discharged with a new prescription for enoxaparin (Lovenox). Which instruction should the nurse include?

• A. Administer the injection in your thigh.
• B. Do not expel the air bubble from the syringe before injection.
• C. Massage the injection site after administration.
• D. Alternate the injection site between the arms.

Correct answer: B

Rationale: The correct instruction for a client with a prescription for enoxaparin (Lovenox) is not to expel the air bubble from the syringe before injection. This ensures the full dose is delivered without affecting the medication's efficacy. Expelling the air bubble may lead to a loss of medication, resulting in suboptimal treatment. Therefore, it is crucial for the client to follow this instruction to receive the intended therapeutic effect of enoxaparin.

4. A client returns to the unit after a neck dissection. The surgeon placed a Jackson-Pratt drain in the wound. When assessing the wound drainage over the first 24 postoperative hours, what finding would prompt the nurse to notify the health care provider immediately?

• A. Presence of small blood clots in the drainage
• B. 60 mL of milky or cloudy drainage
• C. Spots of drainage on the dressings surrounding the drain
• D. 120 mL of serosanguinous drainage

Correct answer: B

Rationale: Milky or cloudy drainage can indicate infection or lymphatic leakage, which requires immediate attention. This finding may suggest a serious complication post neck dissection, warranting prompt notification of the healthcare provider for further evaluation and intervention.

5. 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.
