Correct Answer: A

Rationale: The correct answer is A, Bradycardia. Bradycardia is a common sign of hypoglycemia, which can occur as a complication of insulin therapy in clients with diabetes mellitus. Dry skin (choice B) is not typically associated with hypoglycemia. Increased thirst (choice C) and increased urinary output (choice D) are symptoms more commonly seen in conditions like hyperglycemia or diabetes insipidus, not hypoglycemia.

Correct Answer: A

Rationale: The correct answer is A. A lack of tear production is a sign of severe dehydration in infants, indicating the need for IV therapy. Option B, bulging fontanels, is a sign of increased intracranial pressure, not dehydration. Option C, breathing slower than normal, and Option D, decreasing heart rate, are not specific signs of severe dehydration that would indicate the need for IV therapy in this case.

Correct Answer: A

Rationale: The correct answer is A: 'Develop a safety plan with the client.' When caring for a client who has experienced intimate partner violence, the nurse's priority is to ensure the client's safety. Developing a safety plan is essential to address the immediate safety concerns and provide support to the client. Referring the client to a community support group, as in option B, may be beneficial but is not the immediate priority. While determining if the client has any injuries, as in option C, is important for assessing physical well-being, the priority is to address safety concerns first. Contacting the client's family about the incident, as in option D, is not appropriate without the client's consent and may further endanger the client.
