Correct Answer: D

Rationale: Acupuncture is contraindicated for clients with herpes zoster due to the risk of introducing an open portal on the skin, which can increase the risk of infection. This therapy involves inserting needles into specific points on the body, potentially causing skin trauma and providing a route for the virus to spread. Biofeedback, aloe, and feverfew are not contraindicated for clients with herpes zoster and can be considered for pain management in this condition. Biofeedback involves using electronic devices to help individuals learn to control physiological processes, aloe is a plant known for its skin-soothing properties, and feverfew is an herb that has been used for pain relief.

Correct Answer: D

Rationale: The most crucial action for the nurse to take when caring for a client in restraints is to release the restraints every 2 hours for repositioning. This practice helps prevent complications such as pressure ulcers and impaired circulation by ensuring adequate blood flow and preventing skin breakdown. Checking the client's circulation every hour (Choice A) is important, but releasing the restraints for repositioning takes precedence to prevent serious complications. While documenting the reason for restraints (Choice B) is essential for legal and documentation purposes, it is not as critical as providing necessary care to the client's physical well-being. Providing range-of-motion exercises (Choice C) is beneficial for maintaining mobility but may not address the immediate risks associated with prolonged restraint use.

Correct Answer: D

Rationale: The correct answer is D, Occupational therapist. Occupational therapists specialize in assisting clients with adaptive devices to enhance their ability to perform daily activities like self-feeding. They evaluate client needs and provide interventions to promote independence in activities of daily living. Choice A, Social worker, focuses on psychosocial support and community resources, not directly addressing the physical aspect of self-feeding difficulty. Choice B, Certified nursing assistant, is involved in direct patient care but lacks specialized training in adaptive devices. Choice C, Registered dietitian, primarily focuses on nutrition-related issues and may not have the expertise in adaptive devices and functional rehabilitation necessary for this client's self-feeding challenges.

Correct Answer: B

Rationale: To ensure proper administration through a nasogastric tube, the LPN/LVN should flush the tube with 30 ml of water before and after medication administration. This action helps ensure the tube is patent, prevents clogging, and helps deliver the medication effectively. Checking the placement of the tube by auscultation (Choice A) is essential but does not directly relate to ensuring proper administration. Administering the medication with food (Choice C) may not always be appropriate for all medications and may not necessarily prevent nausea. Diluting the medication with normal saline (Choice D) is not a standard practice for all medications administered via an NG tube and may alter the medication's effectiveness.

Correct Answer: D

Rationale: The correct answer is to dilute the potassium chloride in an appropriate IV solution. Potassium chloride should never be administered as a rapid IV push as it can lead to severe complications, including cardiac arrhythmias. Diluting the medication and administering it slowly helps reduce the risk of adverse effects. Monitoring the client's respiratory rate (Choice A) and checking urine output (Choice B) are important aspects of patient assessment but not the most crucial when administering potassium chloride. Administering potassium chloride as a rapid IV push (Choice C) is dangerous and can result in serious harm to the client.
