A client is post-operative day two from a total hip arthroplasty. The nurse notices the surgical wound is red and warm to the touch. What is the most appropriate action?

Correct Answer: D

Rationale: The correct action when a nurse notices redness and warmth at the surgical wound post total hip arthroplasty is to notify the healthcare provider. These signs may indicate an infection, and prompt evaluation by the healthcare provider is crucial to initiate appropriate treatment. Applying an ice pack (Choice A) may not address the underlying issue of a potential infection. Monitoring the client's temperature (Choice B) is important but not the priority when signs of infection are present. Documenting the findings and continuing to monitor (Choice C) is necessary but should be accompanied by notifying the healthcare provider for further assessment and intervention.

Correct Answer: A

Rationale: The correct answer is A: Serotonin. Serotonin plays a vital role in mood regulation, and its imbalance is often associated with depression. Many antidepressants function by boosting serotonin levels in the brain. Dopamine (Choice B) is more linked to reward and pleasure pathways in the brain, not primarily targeted for mood regulation. GABA (Choice C) is an inhibitory neurotransmitter that helps reduce neuronal excitability, not primarily associated with mood regulation. Acetylcholine (Choice D) is involved in muscle movement and cognitive functions, not the primary target of antidepressants for mood regulation.

Correct Answer: C

Rationale: Sundowning, a phenomenon where dementia symptoms worsen in the evening, can be managed by ensuring the client is close to the nurses' station for frequent monitoring and quick intervention, if necessary. This reduces the risk of harm and helps manage agitation. Asking family members to remain with the client may not always be feasible and does not address the need for close monitoring. Administering benzodiazepines should not be the first-line intervention for sundowning as it can increase the risk of falls and other adverse effects. Postponing medication administration may disrupt the client's routine and potentially worsen symptoms.

Correct Answer: A

Rationale: The olfactory nerve (Cranial Nerve I) is indeed responsible for the sense of smell. It is located in the nasal cavity and transmits olfactory information to the brain. The optic nerve (Choice B) is responsible for vision, the trigeminal nerve (Choice C) is responsible for sensation in the face, and the vagus nerve (Choice D) is responsible for various functions such as heart rate, digestion, and speech. Therefore, the correct answer is the olfactory nerve (Choice A).

Correct Answer: A

Rationale: According to the principle of asepsis, the one-inch border around the edges of a sterile field set up in the operating room is considered non-sterile, while the central area remains sterile. Therefore, the PN should consider the situation described in choice A to be sterile. Choice B is incorrect because a glove that may have touched hair is contaminated. Choice C is incorrect as a sterile item placed on a damp surface is considered contaminated. Choice D is incorrect as a sterile kit set up at the PN's waist level is prone to contamination.

Correct Answer: A

Rationale: The practical nurse should record the findings and report the symptoms to the charge nurse. These behaviors may indicate a serious underlying condition such as depression or physical illness. By reporting to the charge nurse, the client can receive appropriate assessment and intervention promptly. Choice B is incorrect as family visits may not address the root cause of the symptoms. Choice C is incorrect as it oversimplifies the situation and may not be effective in addressing the underlying issue. Choice D is incorrect because withholding medications without proper assessment and guidance can be harmful to the client's health.

Correct Answer: A

Rationale: The correct intervention for a client with Alzheimer's disease in an extended care facility is to plan to have the same nursing staff provide care whenever possible. Consistency in caregivers helps reduce confusion and anxiety in clients with Alzheimer's disease, promoting a stable and supportive environment for the client. Choice B is incorrect as it focuses on activities rather than the consistency of caregivers. Choice C is incorrect as it suggests isolating the client, which can lead to increased confusion and distress. Choice D is incorrect as introducing the client to new people immediately can be overwhelming and may exacerbate their symptoms.

Correct Answer: C

Rationale: A positive indirect Coombs test indicates that the mother's Rh antibodies have crossed the placenta and are present in the neonatal blood, which can lead to hemolytic disease of the newborn. This finding necessitates close monitoring and potential intervention. Choice A is incorrect because a positive Coombs test does not indicate an infectious blood-borne disease. Choice B is incorrect as phototherapy for physiologic jaundice is not related to a positive Coombs test result. Choice D is incorrect because a positive Coombs test does not indicate that the mother no longer needs Rho immune globulin injections; in fact, it suggests a need for further management to prevent hemolytic disease of the newborn.

Correct Answer: D

Rationale: Providing gentle and meticulous mouth care is critical for a client with stomatitis as it helps prevent further irritation and infection of the mucous membranes. Keeping the room environment free of unpleasant odors (Choice A) is important for the client's comfort but not directly related to managing stomatitis. Gathering supplies for protective environmental precautions (Choice B) is not relevant to addressing stomatitis. Assisting the client with feeding at meal times (Choice C) is important for overall care but does not specifically target the care needed for stomatitis.
