Correct Answer: B

Rationale: The correct answer is 'Hypokalemia.' The potassium level of 1.9 indicates low potassium levels, a condition known as hypokalemia. The other lab values are within normal ranges: Hgb 12.6, WBC 6500, uric acid 7.0, Na+ 136, and platelets 178,000. Hypernatremia (choice
A) refers to high sodium levels, which are not present in this case. Myelosuppression (choice
C) is a decrease in bone marrow activity, which is not indicated by the lab values provided. Leukocytosis (choice
D) is an increase in white blood cells, which is also not present based on the given values.

Correct Answer: A

Rationale: The primary responsibility of the nurse is to take the vital signs before any surgery. This action helps assess the client's baseline condition and identify any abnormalities that need addressing before the procedure. Obtaining the permit (choice
B) is typically handled by administrative staff, explaining the procedure (choice
C) is usually done by the healthcare provider performing the surgery, and checking the lab work (choice
D) is often part of the pre-operative assessment conducted by the healthcare provider.
Therefore, in this context, these actions are not the primary responsibility of the nurse.

Correct Answer: B

Rationale: The most appropriate assignment for a nursing assistant is to take the vital signs of a stable patient. A 10-year-old with a 2-day postappendectomy is considered stable, and routine vital signs monitoring can be safely delegated to a nursing assistant. Clients with bronchiolitis, periorbital cellulitis, and a fractured tibia require more specialized care and assessment by a licensed nurse. Bronchiolitis involves an airway alteration, periorbital cellulitis indicates an infection, and a fractured tibia may raise concerns of abuse.
Therefore, options A, C, and D are incorrect for delegation to a nursing assistant.

Correct Answer: B

Rationale: In a client with severe burns to the face and neck, airway assessment and supplemental oxygen are crucial.
Therefore, applying oxygen is the priority to ensure adequate oxygenation for the client. This intervention takes precedence over other actions to stabilize the client's condition. Starting an IV for fluid resuscitation is the next appropriate step following ensuring oxygenation (
Choice
A). While pain management is important, it is a secondary priority after ensuring oxygenation and fluid resuscitation, making medicating the client for pain a later intervention (
Choice
D). Obtaining blood gases (
Choice
C) is not the immediate priority in this scenario and would typically be ordered by the healthcare provider based on the client's condition and response to initial interventions.

Correct Answer: A

Rationale: The correct answer is 'Fraud.' Identifying oneself as a nurse without a license defrauds the public and can lead to prosecution. A tort is a wrongful act in breach of a legal duty imposed by law; malpractice is the failure to act appropriately as a nurse or acting in a way that harm comes to the client; and negligence is failing to perform care. In this scenario, the key issue is the misrepresentation of licensure status, which constitutes fraud.
Therefore, choices B, C, and D are incorrect.
