Correct Answer: D

Rationale: The correct answer is D, tingling of the lips (perioral tingling). This is a common symptom of hypocalcemia due to increased neuromuscular excitability. Choice A, decreased deep-tendon reflexes, is more indicative of hypercalcemia. Choice B, skeletal muscle weakness, is associated with hypokalemia. Choice C, hypoactive bowel sounds, is not a typical finding in hypocalcemia.

Correct Answer: A

Rationale: The correct answer is A. Using sugar-free gum can help alleviate the metallic taste often experienced during chemotherapy treatments. Choices B, C, and D are incorrect. Drinking fluids at mealtime may worsen early satiety, foods higher in fat can exacerbate nausea, and raw fruits and vegetables may be harder for the body to digest and may pose a risk of infection for individuals with compromised immune systems.

Correct Answer: A

Rationale: The correct action for the nurse to take next is to stay with the client and observe for airway obstruction. This is crucial as it ensures immediate intervention if there is any airway compromise. Choice B is incorrect as padding the side rails of the bed is not the priority in this situation. Choice C is incorrect because inserting an oral airway and suctioning should only be done if there is evidence of airway obstruction, and it is not the initial step. Choice D is incorrect as announcing a cardiac arrest and assisting with intubation is not the immediate action needed when a client is seizing and losing consciousness.

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.
