A patient tells the nurse, “I’ve been having problems getting a good night’s sleep. I read some information on the Internet and started taking kava kava.” Select the nurse’s priority response.

Correct Answer: B

Rationale: The correct answer is B. The FDA warning against using kava kava due to potential liver damage makes it the priority response. Firstly, addressing the potential harm from kava kava ensures patient safety. Secondly, it emphasizes the importance of consulting healthcare professionals for reliable information. Choice A lacks specificity and may not address the seriousness of the situation. Choice C introduces a new treatment without addressing the current issue. Choice D makes assumptions about the patient's condition without proper assessment, potentially leading to overlooking serious health risks.

Correct Answer: A

Rationale: The correct answer is A: Fish oil. Fish oil contains omega-3 fatty acids that can increase the risk of bleeding when taken with warfarin, an anticoagulant. This combination can lead to excessive bleeding. Black cohosh, lavender, and mandarin do not have known interactions with warfarin. It is essential for the nurse to caution the patient to avoid fish oil to prevent potential complications.

Correct Answer: A

Rationale: The correct answer is A: Yoga. Yoga is suitable for improving both mental and physical well-being. It incorporates physical postures, breathing exercises, and meditation, promoting relaxation and stress reduction. Other choices can also have benefits but may not address both mental and physical aspects comprehensively. Exercise (B) is beneficial mainly for physical health. Meditation (C) is effective for mental well-being but may not cover physical aspects. Aromatherapy (D) focuses on mental well-being through scents, but it may not address physical well-being directly. Therefore, suggesting yoga covers both mental and physical well-being, making it the appropriate choice.

Correct Answer: C

Rationale: The correct answer is C: Grey matter. Grey matter contains neural cell bodies, axon terminals, dendrites, and all nerve synapses. The cerebellum, cerebrum, brain stem, and butterfly-shaped portion of the central spinal cord are regions of the brain and spinal cord rich in grey matter. White matter (choice B) contains mostly axons and serves to connect different parts of the nervous system. The frontal lobe (choice A) is a specific region of the cerebrum responsible for higher cognitive functions. The corpus callosum (choice D) is a structure connecting the two hemispheres of the brain, composed of white matter. Therefore, C is the correct answer as it accurately describes the composition of the mentioned brain regions.

Correct Answer: A

Rationale: The correct answer is A: Hippocampus. The hippocampus is responsible for the formation and consolidation of long-term memories. It plays a crucial role in memory encoding and retrieval processes. Damage to the hippocampus can lead to difficulties in forming new memories. B: Parietal lobe is involved in sensory processing and spatial orientation. C: Temporal lobe is important for memory and auditory processing, but the hippocampus within the temporal lobe is specifically responsible for long-term memory. D: Occipital lobe is primarily responsible for visual processing. In summary, the hippocampus is the correct answer as it is specifically associated with regulating long-term memory, while the other brain areas have different functions unrelated to long-term memory regulation.
