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: C

Rationale: Rationale: - A: Diuretics are not necessary before the test and may affect test results. - B: Dehydration is not recommended before the test as it can impact cardiac function. - C: Medication to relieve cough is necessary to reduce any potential interference with the scan. - D: Administering analgesics is not required for the test and may not be relevant to the client's condition.

Correct Answer: D

Rationale: The correct answer is D: �I will receive parenteral vitamin B12 therapy for the rest of my life.� This statement is correct because pernicious anemia is a lifelong condition requiring ongoing vitamin B12 supplementation. Patients with pernicious anemia lack intrinsic factor, which is needed to absorb vitamin B12 from food. Therefore, they need lifelong B12 therapy to prevent complications such as anemia and neurological damage. Choices A, B, and C are incorrect because they suggest a limited duration of therapy. Pernicious anemia is a chronic condition that necessitates continuous treatment. Choice A implies therapy until signs and symptoms disappear, which may not address the underlying cause of the deficiency. Choice B mentions therapy until vitamin B12 levels normalize, which may not prevent recurrence. Choice C suggests monthly therapy for a fixed period, which may not be sufficient for lifelong management.

Correct Answer: B

Rationale: The correct answer is B: Interpersonal. The nurse is using interpersonal skills by establishing trust and communicating with the patient before administering the injection. This helps build rapport and alleviate anxiety. Cognitive skills involve problem-solving and critical thinking, not direct patient interaction. Psychomotor skills relate to physical tasks like giving injections. Judgmental skills involve making decisions based on critical thinking, not directly related to patient communication.

Correct Answer: C

Rationale: The correct initial treatment for stage IV ovarian cancer is major surgery (Choice C). This is because at this advanced stage, surgery is typically performed to debulk the tumor and remove as much cancerous tissue as possible, followed by chemotherapy to target any remaining cancer cells. Radiation therapy (Choice A) is not typically the initial treatment for ovarian cancer. Chemotherapy (Choice B) is often used in combination with surgery, but surgery is usually the first line of treatment for stage IV disease. Choosing no treatment (Choice D) would be detrimental as the cancer is advanced and requires immediate intervention.
