Correct Answer: C

Rationale: The correct answer is C: An incision near the diaphragm. Following a splenectomy, an incision near the diaphragm can lead to respiratory complications due to potential irritation or injury to the diaphragm. This can result in impaired breathing and increased risk of respiratory issues such as pneumonia. A: A low platelet count is not directly related to respiratory complications following a splenectomy. B: Early ambulation is generally encouraged to prevent complications such as blood clots but does not specifically impact respiratory complications. D: Early discharge may not directly lead to respiratory complications, as long as the patient is adequately monitored postoperatively.

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.

Correct Answer: B

Rationale: The correct answer is B: Ask the patient to describe the type of reaction. This is the first action the nurse should take to assess the severity of the latex allergy and determine appropriate interventions. By gathering more information about the reaction, the nurse can better understand the potential risks and provide safe care. Summary of other choices: A: Immediately placing the patient in isolation is unnecessary and not indicated based solely on the patient's latex allergy. C: Proceeding to the termination phase of the interview is premature without fully assessing the patient's allergy. D: Documenting the allergy is important but should not be the first action without assessing the reaction itself.

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: B

Rationale: The correct answer is B (AB). AB blood type is the rarest because it is a result of inheriting both A and B alleles, making it less common in the population. AB individuals can only receive blood from other AB individuals due to their unique antigens. Blood types A, B, and O are more common in the population, with O being the most common as it is the universal donor. Blood type A and B are more common than AB since they only require one allele for their respective antigens. Thus, the rarity of AB blood type is due to the inheritance of both A and B alleles, making it the least common among the choices provided.
