Nursing Elites

1. A client with coronary artery disease (CAD) is prescribed atorvastatin (Lipitor). Which laboratory value requires immediate intervention?

• A. Total cholesterol of 180 mg/dL.
• B. Low-density lipoprotein (LDL) of 200 mg/dL.
• C. Triglycerides of 150 mg/dL.
• D. High-density lipoprotein (HDL) of 40 mg/dL.

Correct answer: B

Rationale: An LDL level of 200 mg/dL is significantly elevated and requires immediate intervention to reduce the risk of cardiovascular events in a client with coronary artery disease (CAD). High LDL levels contribute to the development and progression of atherosclerosis, which can lead to complications like heart attacks and strokes. Lowering LDL levels is a key goal in managing CAD and preventing further cardiovascular damage. Total cholesterol of 180 mg/dL, triglycerides of 150 mg/dL, and HDL of 40 mg/dL are within acceptable ranges and do not pose an immediate risk that necessitates urgent intervention.

2. A 70-year-old woman presents with fatigue, anorexia, and weight loss. She has noticed darkening of her skin, particularly in sun-exposed areas. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

• A. Cushing's syndrome
• B. Addison's disease
• C. Hypothyroidism
• D. Pheochromocytoma

Correct answer: B

Rationale: The combination of symptoms such as fatigue, anorexia, weight loss, hyperpigmentation of the skin, along with hyponatremia, hyperkalemia, and low cortisol levels, points towards Addison's disease. This condition is characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production.

3. The nurse is caring for a client with a history of deep vein thrombosis (DVT) who is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

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

Correct answer: B

Rationale: Prothrombin time (PT) is monitored to ensure therapeutic levels of warfarin and prevent bleeding complications.

4. 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.

5. A client with chronic kidney disease (CKD) is scheduled for hemodialysis. Which pre-dialysis assessment finding should the nurse report to the healthcare provider?

• A. Serum potassium of 5.5 mEq/L.
• B. Blood pressure of 180/90 mm Hg.
• C. Heart rate of 80 beats per minute.
• D. Serum sodium of 140 mEq/L.

Correct answer: B

Rationale: The correct answer is B. A blood pressure of 180/90 mm Hg is elevated and should be reported to the healthcare provider before hemodialysis. Hypertension can have a significant impact on the effectiveness and safety of the dialysis treatment. Controlling blood pressure before the procedure is crucial to prevent complications during the dialysis session.
