Correct Answer: D

Rationale: The correct action the nurse should add to the client's plan of care is to have a tongue depressor available at the client's bedside. This is important during a seizure to prevent the client from biting their tongue. Placing the client laterally helps maintain a clear airway and prevents aspiration, making choice C a good practice during seizure activity. Using restraints during a seizure can cause injuries and should be avoided, making choice B incorrect. Wrapping blankets around all four sides of the bed is unnecessary for seizure management and does not contribute to the client's safety during a seizure, making choice A incorrect.

Correct Answer: A

Rationale: A credible threat is the correct term used to identify a situation where a reliable source specifies both the target and method of attack, such as a bomb possessed by a known terrorist group targeting a government building in a local community. This term signifies a serious and imminent danger substantiated by credible information. Choice B, 'Biological event,' is incorrect as it refers to a different type of threat involving pathogens or biological agents. Choice C, 'National disaster,' is also incorrect as it pertains to large-scale events causing significant harm to a country or region, not a specific targeted attack. Choice D, 'All-hazards approach,' is not the term used to describe a specific identified threat; instead, it refers to a comprehensive strategy that addresses all types of hazards and risks in emergency management.

Correct Answer: A

Rationale: The charge nurse should intervene when a nurse photocopies a client's diagnostic test results as it violates patient confidentiality and privacy. This action breaches HIPAA regulations, and sensitive patient information should not be photocopied without proper authorization. The other actions are within the scope of practice and do not raise concerns regarding patient privacy or confidentiality.

Correct Answer: C

Rationale: Functional nursing is a care delivery model where tasks are divided among team members based on their respective roles. In this system, RNs, LPNs, and unlicensed assistive personnel are assigned specific tasks to carry out for the entire nursing unit, such as medication administration or personal hygiene duties. The other choices are incorrect: A) Primary nursing involves one nurse being responsible for all aspects of care for a group of patients, B) Team nursing involves a team of healthcare providers working together to provide care for a group of patients, and D) Total patient care refers to one nurse being responsible for all aspects of care for one patient.

Correct Answer: A

Rationale: In a patient admitted with diabetic ketoacidosis, the initial priority is to address dehydration and electrolyte imbalances. Infusing 1 liter of normal saline per hour helps correct hypovolemia and restore electrolyte balance, making it the first essential step in managing diabetic ketoacidosis. Sodium bicarbonate is not routinely recommended in treating diabetic ketoacidosis and should not be given routinely as it may worsen the acidosis. Administering regular insulin and starting an insulin infusion are important but should come after fluid resuscitation to stabilize the patient's condition.
