Nursing Elites

1. A nurse contacts the healthcare provider after reviewing a client’s laboratory results and noting a blood urea nitrogen (BUN) of 35 mg/dL and a creatinine of 1.0 mg/dL. For which action should the nurse recommend a prescription?

• A. Intravenous fluids
• B. Hemodialysis
• C. Fluid restriction
• D. Urine culture and sensitivity

Correct answer: A

Rationale: The normal range for BUN is 10 to 20 mg/dL, and for creatinine, it is 0.6 to 1.2 mg/dL in males and 0.5 to 1.1 mg/dL in females. Creatinine is a more specific marker for kidney function compared to BUN. In this case, the client's creatinine level is within the normal range, indicating a non-renal cause for the elevated BUN. Dehydration is a common cause of increased BUN, so the appropriate action would be to recommend intravenous fluids to address the dehydration. Fluid restriction is not indicated as the client needs hydration. Hemodialysis is not appropriate for dehydration and is typically reserved for renal failure. The laboratory results do not suggest an infection, making a urine culture and sensitivity unnecessary in this scenario.

2. The healthcare provider is assessing an older Caucasian male who has a history of peripheral vascular disease. The healthcare provider observes that the man's left great toe is black. The discoloration is probably a result of:

• A. Atrophy.
• B. Contraction.
• C. Gangrene.
• D. Rubor.

Correct answer: C

Rationale: Gangrene refers to dead, blackened tissue, often a result of chronic ischemia in clients with peripheral vascular disease. Atrophy (Choice A) is the wasting away or decrease in size of tissue or organ. Contraction (Choice B) refers to the shortening or tightening of a muscle or other body part. Rubor (Choice D) is a red discoloration of the skin, often associated with inflammation or poor circulation, but not typically presenting as blackening like gangrene.

3. The healthcare provider is developing standards of care for a client with gastroesophageal reflux disease and wants to review current evidence for practice. Which one of the following resources will provide the most helpful information?

• A. A review in the Cochrane Library.
• B. A literature search in a database, such as the Cumulative Index to Nursing and Allied Health Literature (CINAHL).
• C. An online nursing textbook.
• D. The policy and procedure manual at the healthcare agency.

Correct answer: A

Rationale: The Cochrane Library provides systematic reviews of primary research in healthcare, making it a reliable resource for evidence-based practice. Choice B, a literature search in a database like CINAHL, may also be useful but does not guarantee the same level of systematic review and reliability as the Cochrane Library. Choice C, an online nursing textbook, may offer information but might not provide the most current or evidence-based practices. Choice D, the policy and procedure manual at the healthcare agency, is unlikely to offer the comprehensive evidence-based information needed for developing standards of care.

4. When performing a health history on a patient who is to begin receiving a thiazide diuretic to treat heart failure, the nurse will be concerned about a history of which condition?

• A. Asthma
• B. Glaucoma
• C. Gout
• D. Hypertension

Correct answer: C

Rationale: Thiazide diuretics block uric acid secretion, leading to elevated levels that can contribute to gout. Therefore, patients with a history of gout should take thiazide diuretics with caution. Asthma (Choice A), Glaucoma (Choice B), and Hypertension (Choice D) are not directly contraindicated with thiazide diuretics, making choices A, B, and D incorrect.

5. Which of the following conditions is the most significant risk factor for the development of type 2 diabetes mellitus?

• A. Cigarette smoking.
• B. High-cholesterol diet.
• C. Obesity.
• D. Hypertension.

Correct answer: C

Rationale: Obesity is the most significant risk factor for developing type 2 diabetes mellitus due to its role in insulin resistance. Excess body fat, especially around the abdomen, leads to increased production of inflammatory markers and hormones that can cause insulin resistance. While cigarette smoking, high-cholesterol diet, and hypertension can contribute to health issues, they are not as directly linked to the development of type 2 diabetes mellitus as obesity.
