LPN Nutrition Practice Test

Correct Answer: B

Rationale: The correct answer is B: Ensure strict infection control measures. Children with acute lymphoblastic leukemia (ALL) who are undergoing chemotherapy have compromised immune systems, making them highly susceptible to infections. Implementing strict infection control measures, such as hand hygiene, limiting exposure to sick individuals, and maintaining a clean environment, is essential to prevent infections. Choice A is incorrect because avoiding all physical activity may not be necessary as long as the child's activity level is appropriate. Choice C is incorrect because increasing daily caloric intake is important to support the child's nutritional needs during treatment. Choice D is incorrect because limiting fluid intake is not typically recommended unless specifically advised by the healthcare provider.

Correct Answer: B

Rationale: The correct answer is B: Adequate hydration and pain management. During a sickle cell crisis, it is essential to provide hydration to prevent vaso-occlusive events and manage pain effectively with analgesics. Adequate hydration helps maintain blood flow and prevent further sickling of red blood cells. Pain management is crucial to alleviate the severe pain associated with sickle cell crises. Options A, C, and D are incorrect. Providing information for parents on home care (Option A) may be important for ongoing management but is not specific to an acute crisis. Iron supplements (Option C) are not typically indicated during a sickle cell crisis. Adequate oxygenation and factor VIII (Option D) are not primary interventions for managing a sickle cell crisis; instead, oxygen therapy may be considered in severe cases, and factor VIII is not a standard treatment for sickle cell disease.

Correct Answer: D

Rationale: The correct answer is D. Carbohydrates are the body's primary source of energy, fueling daily activities and bodily functions. Choice A is incorrect because insulation and organ support are primarily provided by adipose tissue and structural proteins, not carbohydrates. Choice B is incorrect because the regulation of body temperature is mainly controlled by processes like sweating and shivering, not carbohydrates. Choice C is incorrect because structural components like proteins are responsible for building tissues and organs, not carbohydrates.

Correct Answer: A

Rationale: The correct answer is A: Joint swelling and pain. These are the most common initial symptoms of juvenile idiopathic arthritis, typically affecting multiple joints. Skin rash (choice B), gastrointestinal bleeding (choice C), and neurological deficits (choice D) are not typical initial symptoms of juvenile idiopathic arthritis. Skin rash may be seen in other conditions like dermatitis or systemic lupus erythematosus, gastrointestinal bleeding may be associated with conditions like inflammatory bowel disease, and neurological deficits could be indicative of conditions like multiple sclerosis.

Correct Answer: A

Rationale: The main purpose of Recommended Dietary Allowances (RDAs) is to provide guidelines for nutrient intakes that meet the needs of most healthy people. Choice B is incorrect because RDAs aim beyond just survival requirements. Choice C is incorrect because establishing maximum safe levels is the role of Tolerable Upper Intake Levels (ULs). Choice D is incorrect because preventing chronic diseases is more associated with Dietary Reference Intakes (DRIs) like Adequate Intakes (AIs) and Tolerable Upper Intake Levels (ULs). Therefore, the correct answer is A.
