Rationale: Pediculicides are the recommended treatment for lice and should be used to eliminate the infestation.

Correct Answer: A

Rationale: Peanut butter and enriched bread provide complementary proteins, which are important for a vegetarian diet. Peanut butter is a good source of protein and when paired with enriched bread, it forms a complete protein source. Choice B, baked potato with sour cream, lacks complete protein. Choice C, bagel with cream cheese, also does not provide a complete protein source. Choice D, fruit salad and carrot sticks, do not contain sufficient protein to serve as a main protein source for a vegetarian diet.

Correct Answer: B

Rationale: The correct answer is B, Chvostek's sign. This is a classic sign of hypocalcemia, which can occur after a thyroidectomy due to injury or removal of the parathyroid glands. Hypocalcemia can lead to serious complications like tetany and laryngospasm, necessitating immediate attention. Assessing Chvostek's sign helps in early identification and management of hypocalcemia. Choices A, C, and D are not the priority in this situation. While assessing the calcium level is important for diagnosing hypocalcemia, the immediate concern is to identify clinical signs like Chvostek's sign, which indicate acute hypocalcemia. Trousseau's sign is also related to hypocalcemia but is not the most critical sign to assess first. Serum potassium level, although important for overall electrolyte balance, is not directly related to the client's current symptoms of tingling in the fingers and around the mouth.

Correct Answer: A

Rationale: The correct answer is A because monitoring for orthostatic hypotension is crucial when clients are receiving antipsychotic drugs since it is a common side effect. Orthostatic hypotension can lead to symptoms like dizziness and falls, making it essential to monitor blood pressure regularly. Choices B, C, and D are incorrect because most antipsychotic drugs do not typically cause elevated blood pressure, monitoring blood pressure is not directly related to the amount of sodium in the diet, and blood pressure monitoring is not primarily used to determine the need for anti-parkinsonian drugs in clients receiving antipsychotic medications.

Correct Answer: C

Rationale: The most crucial information to prevent the spread of lice in schools is to avoid sharing hats, scarves, and combs. This is important as lice can easily spread through shared personal items. Choices A, B, and D are not as critical as choice C in preventing the spread of lice. Reapplication of treatment, boiling or steaming bedding and clothing, and using nit combs are important but not as crucial as avoiding the sharing of personal items.
