LPN Fundamentals Practice Questions

Correct Answer: A

Rationale: The correct answer is A: 'I should avoid foods that contain lactose.' Lactose intolerance results from the inability to digest lactose, a sugar found in dairy products. Avoiding foods that contain lactose is essential in managing symptoms like bloating, diarrhea, and abdominal pain. Choice B is incorrect because increasing dairy intake would worsen symptoms. Choice C is incorrect because gluten is unrelated to lactose intolerance. Choice D is incorrect because high-fiber foods are beneficial for other conditions but do not specifically address lactose intolerance.

Correct Answer: B

Rationale: The correct answer is B because reducing dairy product intake can help manage symptoms of ulcerative colitis. Dairy products can exacerbate symptoms in some individuals due to their lactose content and may need to be limited or avoided based on individual tolerance levels. Choice A is incorrect because increasing dairy products can worsen symptoms for some ulcerative colitis patients. Choice C is incorrect as while high-fiber foods are generally beneficial, they may exacerbate symptoms during a flare-up. Choice D is also incorrect as while reducing high-fat foods can be beneficial, dairy products are a more specific concern for ulcerative colitis.

Correct Answer: B

Rationale: The correct answer is B. Decreasing the intake of purine-rich foods is essential in managing gout as purines break down into uric acid, contributing to gout symptoms. Increasing purine-rich foods would exacerbate the condition by increasing uric acid levels. Therefore, choice A is incorrect. Choices C and D are also incorrect as increasing sodium-rich foods (choice C) is not recommended for gout management, and decreasing potassium-rich foods (choice D) is unrelated to gout.

Correct Answer: B

Rationale: When administering a subcutaneous injection, inserting the needle at a 90-degree angle is appropriate. This angle helps ensure proper delivery of the medication into the subcutaneous tissue. Using a 1-inch needle is common for subcutaneous injections to reach the subcutaneous fat layer adequately. Tuberculin syringes are typically used for intradermal injections, not subcutaneous injections. Aspirating before injecting is not necessary for subcutaneous injections as it is primarily used for intramuscular injections to ensure the needle is not in a blood vessel.

Correct Answer: A

Rationale: The correct answer is A: 'I should increase my intake of foods high in iron.' Iron-deficiency anemia is managed by increasing the consumption of iron-rich foods to improve iron levels in the body. Foods high in iron include red meat, poultry, fish, beans, lentils, and iron-fortified cereals. Choices B, C, and D are incorrect because decreasing intake of iron-rich foods or increasing intake of calcium-rich foods would not address the deficiency in iron levels that characterizes iron-deficiency anemia.
