An adult is to receive narcotic analgesics via patient controlled analgesia. The nurse is evaluating client’s understanding of the procedure. Which of the following statements by the client indicates that she understand PCA?

Correct Answer: B

Rationale: The correct answer is B: "I will press the button whenever I feel pain." This answer demonstrates understanding of how patient-controlled analgesia (PCA) works, where the client self-administers medication when needed for pain relief. Option A is incorrect as the machine is programmed with lockout intervals to prevent overdosing. Option C is incorrect as the client should only press the button when experiencing pain, not on a fixed schedule. Option D is incorrect as PCA does not guarantee complete pain elimination. The key in PCA is empowering the client to self-administer medication based on their pain level.

Correct Answer: B

Rationale: Correct Answer: B: Calcium should be avoided Rationale: 1. Calcium is an essential mineral for bone health, especially important for individuals with limited mobility like Richard. 2. Avoiding calcium can lead to bone weakening and increase the risk of fractures. 3. Nursing care plans should include adequate calcium intake to support bone health. 4. Therefore, avoiding calcium is not a recommended nutritional consideration. Summary of Incorrect Choices: A: The diet should be semisolid to facilitate the passage of food - This is important for individuals with swallowing difficulties. C: The patient should be sitting in an upright position during feeding - This aids in proper digestion and reduces the risk of aspiration. D: Thick fluids should be encouraged to provide additional calories - Thick fluids may increase the risk of aspiration in patients with neurological conditions.

Correct Answer: C

Rationale: The correct answer is C: To rule out cholinergic crisis caused by Neostigmine. Edrophonium HCL is a fast-acting cholinesterase inhibitor used to differentiate between myasthenic crisis and cholinergic crisis. If the patient's weakness improves after administration of edrophonium, it indicates that the weakness was due to myasthenia gravis and not cholinergic crisis caused by excessive neostigmine. Choice A is incorrect because there is no synergestic effect between neostigmine and edrophonium. Choice B is incorrect as resistance to neostigmine is not a valid reason for ordering edrophonium. Choice D is incorrect because edrophonium is used for differential diagnosis, not for confirming the diagnosis of myasthenia gravis.

Correct Answer: A

Rationale: The correct answer is A because shampooing the hair thoroughly helps remove oil and dirt, which can interfere with the CT scan results. By having clean hair, the scan can produce clearer images. Choice B is incorrect because some preparation is needed for a CT scan, especially regarding cleanliness. Choice C is incorrect as giving a cleansing enema and fluids until 8 AM is not necessary for a CT scan of the head. Choice D is incorrect as shaving the scalp and attaching electrodes are not part of routine preparation for a CT scan.

Correct Answer: B

Rationale: The correct answer is B: Clients with metal implants in their body. An MRI uses strong magnetic fields, which can interact with metal implants, causing movement or heating of the metal and potential harm to the client. This could lead to serious injuries or complications during the scan. Overweight clients (choice A), clients over the age of 60 (choice C), and clients with brain tumors (choice D) do not have contraindications for an MRI scan.
