Correct Answer: C

Rationale: The correct answer is C: Penicillin allergy. Penicillin allergy is a contraindication for ceftriaxone because both medications are beta-lactam antibiotics. Seizure disorder (choice A), hypertension (choice B), and hyperlipidemia (choice D) are not contraindications for ceftriaxone and do not directly affect the use of this antibiotic.

Correct Answer: A

Rationale: The correct answer is A: Tingling in the fingers. Tingling in the fingers is a common sign of hypocalcemia, often seen after a thyroidectomy. Hypocalcemia can occur post-thyroidectomy due to inadvertent damage or removal of the parathyroid glands which regulate calcium levels. Choices B, C, and D are incorrect. Elevated blood pressure is not typically associated with hypocalcemia. Positive Chvostek's sign is a clinical sign of hypocalcemia but is usually assessed as facial muscle twitching, not tingling in the fingers. Positive Kernig's sign is a test for meningitis, not related to hypocalcemia.

Correct Answer: D

Rationale: The correct answer is D, a heart rate of 160/min. A heart rate of 160/min in a newborn exceeds the normal range and could indicate potential issues that need further evaluation by the provider. Acrocyanosis (choice A) is a common finding in newborns and is not concerning. Vernix caseosa (choice B) is a white, cheesy substance found on newborn skin and is a normal finding. While a respiratory rate of 50/min (choice C) is slightly elevated, it is not as concerning as a high heart rate in a newborn.

Correct Answer: A

Rationale: The correct answer is A: Establish a toileting schedule for the client. A toileting schedule helps manage incontinence and prevent accidents, promoting client dignity. Choice B is incorrect because clothing with buttons and zippers may be difficult for a client with dementia to manage independently. Choice C is incorrect as physical activity during the day is beneficial for clients with dementia. Choice D is incorrect as activities that increase sensory stimulation may be overwhelming for a client with dementia.
