Correct Answer: A

Rationale: The correct answer is A: Negligence. Negligence in nursing occurs when a healthcare provider fails to take appropriate action that a reasonably prudent provider would take in a similar situation, such as not notifying the provider of changes in a client's condition. In this scenario, the nurse's failure to inform the provider of the client's changed condition constitutes negligence. Choices B, C, and D are incorrect. Assault involves the intentional threat of bodily harm to another person, battery is the intentional harmful or offensive touching of another person without their consent, and defamation is the act of making false statements about someone to a third party that harms that person's reputation.

Correct Answer: A

Rationale: Encouraging early ambulation is crucial in reducing the risk of postoperative complications, such as blood clots and pneumonia. Early mobilization helps prevent complications like deep vein thrombosis and pneumonia by promoting circulation and preventing respiratory complications. Providing intravenous antibiotics (Choice B) is important for preventing infections but is not the priority immediately post-surgery. Applying anti-embolism stockings (Choice C) is beneficial in preventing venous thromboembolism but does not address the immediate need for mobility. Placing a Foley catheter (Choice D) may be necessary during surgery but is not a priority intervention to reduce postoperative complications related to immobility.

Correct Answer: B

Rationale: The ventrogluteal site is the preferred site for intramuscular injections to avoid injury to nerves or blood vessels. The deltoid site is commonly used for vaccines but has a higher risk of hitting the radial nerve. The rectus femoris site is not typically recommended for intramuscular injections. The dorsogluteal site is contraindicated due to the proximity to the sciatic nerve and major blood vessels.

Correct Answer: B

Rationale: The correct answer is B: 'Wear shoes at all times.' This instruction is crucial for clients with diabetes as it helps protect the feet from potential injuries. Choice A of soaking feet in warm water daily can lead to skin issues and should be avoided. Cutting toenails in a rounded shape, as mentioned in choice C, can increase the risk of ingrown toenails. While inspecting the feet weekly, as in choice D, is important, wearing shoes at all times is a more preventative measure to avoid foot injuries in diabetic clients.

Correct Answer: B

Rationale: An immunization functions as part of acquired immunity. Acquired immunity involves the production of antibodies after immunization, which helps protect against future infections. Natural immunity is not induced by immunization but is present from birth. Passive immunity is temporary and acquired through the transfer of pre-formed antibodies. Cell-mediated immunity is a type of immune response that involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.
