Nursing Elites

1. Which term is used to describe populations located in lower income, inner city, and rural areas with few supermarkets but numerous small stores stocking limited nutritious food items?

• A. Food fad
• B. Food insecurity
• C. Food desert
• D. Food patterns

Correct answer: C

Rationale: A food desert refers to areas with limited access to affordable and nutritious food, often found in lower-income urban and rural areas.

2. What is the glomerular filtration rate for patients with stage 5 chronic kidney disease (CKD)?

• A. Less than 15 mL/min/1.73 m�
• B. Less than 30 mL/min/1.73 m�
• C. Less than 90 mL/min/1.73 m�
• D. Less than 125 mL/min/1.73 m�

Correct answer: A

Rationale: In patients with stage 5 chronic kidney disease (CKD), also known as end-stage renal disease, the kidney function is significantly compromised. This severe condition is characterized by a glomerular filtration rate (GFR) of less than 15 mL/min/1.73 m�, as correctly stated in choice A. Choices B, C, and D suggest higher GFR values, which are not indicative of stage 5 CKD. Specifically, a GFR of less than 30 mL/min/1.73 m� indicates stage 4 CKD, less than 90 mL/min/1.73 m� signifies stage 3 CKD, and a typical healthy individual usually has a GFR of around 125 mL/min/1.73 m�, which is far above the GFR for stage 5 CKD.

3. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?

• A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
• B. Viscous fiber binds with bile in the intestine and is excreted in feces
• C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
• D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol

Correct answer: B

Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.

4. What outcome has been shown to be a benefit of breastfeeding that directly impacts the mother?

• A. conserving calcium stores
• B. contracting the uterus
• C. protecting against future hypertension
• D. speeding the resumption of ovulation

Correct answer: B

Rationale: The correct answer is B, contracting the uterus. Breastfeeding helps contract the uterus after childbirth, reducing postpartum bleeding and helping the uterus return to its pre-pregnancy size more quickly. Choices A, C, and D are incorrect because conserving calcium stores, protecting against future hypertension, and speeding the resumption of ovulation are not direct benefits of breastfeeding to the mother.

5. Baby John develops hyperbilirubinemia. What is a method used to treat hyperbilirubinemia in a newborn?

• A. Keeping infants in a warm and dark environment
• B. Administration of cardiovascular stimulant
• C. Gentle exercise to stop muscle breakdown
• D. Early feeding to speed passage of meconium

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
