Nursing Elites

1. Dina, 17 years old, asks you how a tubal ligation prevents pregnancy. Which would be the best answer?

• A. Prostaglandins released from the cut fallopian tubes can kill sperm
• B. Sperm cannot enter the uterus because the cervical entrance is blocked
• C. Sperm can no longer reach the ova, because the fallopian tubes are blocked
• D. The ovary no longer releases ova as there is nowhere for them to go

Correct answer: C

Rationale: The correct answer is C: 'Sperm can no longer reach the ova because the fallopian tubes are blocked.' Tubal ligation works by blocking the fallopian tubes, preventing sperm from reaching the egg for fertilization. Choice A is incorrect because prostaglandins are not released from the cut fallopian tubes to kill sperm. Choice B is incorrect as the cervical entrance being blocked does not relate to tubal ligation. Choice D is incorrect because tubal ligation does not affect the release of ova from the ovary.

2. A healthcare professional is preparing a list of resources in a community where nutritional status is significantly influenced by economics. What should the professional recommend?

• A. Public service announcement on healthy eating
• B. Educational programs on food safety
• C. The MyPyramid food guidance system
• D. The Supplemental Nutrition Assistance Program (SNAP)

Correct answer: D

Rationale: The correct answer is D, the Supplemental Nutrition Assistance Program (SNAP). SNAP provides financial assistance to help low-income individuals purchase food, directly addressing economic barriers to nutrition. Choices A, B, and C do not directly address the economic aspect of the community's nutritional status. A public service announcement on healthy eating may raise awareness but does not provide financial assistance. Educational programs on food safety focus on a different aspect of nutrition. The MyPyramid food guidance system is a tool for healthy eating but does not address the economic challenges faced by the community.

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. Mrs. Seva also tells the nurse that she is often constipated. Because she is aging, what physical changes predispose her to constipation?

• A. inhibition of the parasympathetic reflex
• B. weakness of sphincter muscles of anus
• C. loss of tone of the smooth muscles of the colon
• D. decreased ability to absorb fluids in the lower intestines

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

5. Select all that apply. Characteristics of the 2 main types of essential fatty acids discussed in class include:

• A. they must be supplied by the diet
• B. they can be produced by a process called dehydrogenation
• C. they are anti-inflammatory
• D. they are all polyunsaturated fatty acids

Correct answer: A

Rationale: The correct answer is A: 'they must be supplied by the diet.' Essential fatty acids, like omega-3 and omega-6, cannot be produced by the body and must be obtained through the diet. They are polyunsaturated fatty acids, playing vital roles in inflammation and cell membrane structure. Choice B is incorrect because essential fatty acids cannot be produced by dehydrogenation, a process of removing hydrogen. Choice C is incorrect as not all essential fatty acids are anti-inflammatory; some have pro-inflammatory roles. Choice D is incorrect because not all essential fatty acids are polyunsaturated; omega-9, for example, is a monounsaturated essential fatty acid.
