LPN Nutrition Practice Test

Correct Answer: C

Rationale: Assisting parents of a SIDS infant in coping involves alleviating feelings of guilt and blame, providing emotional support, and offering appropriate counseling. It is crucial to address the parents' emotional well-being and help them cope with the loss. Choice A is not the best answer as it focuses solely on grief counseling, while the primary concern is addressing feelings of guilt and blame. Choice B is inappropriate as remaining detached does not provide the necessary emotional support these parents need. Choice D is incorrect as discussing the parents' mistakes can intensify their feelings of guilt and blame, rather than helping them cope effectively.

Correct Answer: B

Rationale: The correct answer is B. In a double-blind experiment, neither the subjects nor the researchers know which subjects are in the control or experimental group. This helps to eliminate bias and ensure that the results are more objective. Choice A is incorrect as in a double-blind experiment, subjects do not take turns receiving each treatment; it is about masking the treatment allocation. Choice C is incorrect because it implies that the researchers are aware of the group allocation, which goes against the principle of blinding in a double-blind study. Choice D is incorrect as both subject groups should not know whether they are in the control or experimental group to maintain the blindness of the study.

Correct Answer: C

Rationale: The correct answer is C: Epinephrine injection. An epinephrine injection is the primary treatment for an anaphylactic reaction in children. Epinephrine acts quickly to reverse severe symptoms such as difficulty breathing, low blood pressure, and hives. Oral antihistamines, although useful for milder allergic reactions, are not sufficient to manage the potentially life-threatening symptoms of anaphylaxis. Intravenous fluids may be necessary to support blood pressure in a child with anaphylaxis but are not the primary treatment. Antipyretics, on the other hand, are medications used to reduce fever and are not indicated as the primary treatment for an anaphylactic reaction.

Correct Answer: A

Rationale: Iron supplements are the correct choice for treating iron-deficiency anemia in children. Iron supplements help replenish the low iron levels in the body, addressing the underlying cause of the anemia. High-protein diets may be beneficial for overall health but are not the primary treatment for iron-deficiency anemia. Vitamin B12 injections are used to treat B12 deficiency anemia, a different type of anemia. Sodium chloride solution is not a treatment for anemia and is typically used for hydration purposes.

Correct Answer: C

Rationale: An essential nutrient is a substance that cannot be made in sufficient quantities by the body itself, so it must be obtained from the diet. Choice A is incorrect because essential nutrients are required in specific amounts, not necessarily large quantities. Choice B is incorrect as essential nutrients cannot be synthesized by the body at all. Choice D is incorrect because although essential nutrients may be used in the synthesis of other compounds, that is not the defining characteristic of an essential nutrient.
