A client with a history of cardiac dysrhythmias is admitted to the hospital with the diagnosis of dehydration. The nurse should anticipate that the physician will order;

Correct Answer: B

Rationale: Step-by-step rationale for choice B being correct: 1. Dehydration leads to electrolyte imbalances, which can exacerbate cardiac dysrhythmias. 2. Small frequent intake of fluids like juices, broth, or milk helps in gradual rehydration without overwhelming the cardiovascular system. 3. This approach allows for better absorption of fluids and nutrients, promoting hydration without causing sudden shifts in electrolyte levels. Summary of why other choices are incorrect: A: Just drinking a glass of water every hour may not address electrolyte imbalances or provide adequate hydration for a client with cardiac dysrhythmias. C: NG replacement may not be necessary if the client can tolerate oral intake, and it is more invasive than needed. D: A rapid IV infusion may lead to sudden changes in electrolyte levels, potentially worsening the dysrhythmias.

Correct Answer: A

Rationale: The correct answer is A: Include potassium-rich foods. Diuretics can cause potassium loss, leading to hypokalemia. Including potassium-rich foods helps prevent this deficiency. Choice B is incorrect because fruits and fruit juices are often good sources of potassium. Choice C is incorrect as protein-rich foods do not specifically address potassium needs. Choice D is incorrect as dairy products are also good sources of potassium. Therefore, recommending potassium-rich foods is essential to prevent hypokalemia in clients taking diuretics.

Correct Answer: A

Rationale: The correct answer is A because the drug should be resumed when the WBC count falls to 5,000mm3 to ensure the client's safety and efficacy of treatment. This criterion indicates that the client's immune system has recovered sufficiently to tolerate the drug. Choices B, C, and D are incorrect because they do not directly correlate with the client's immune system recovery, which is crucial for drug tolerance. Choice B focuses on the rise in WBC count, not the fall to a specific level. Choice C is related to a cosmetic side effect, not clinical readiness. Choice D is unrelated to immune system recovery.

Correct Answer: C

Rationale: The correct answer is C: Use the smallest needle possible for injections. This is important for a client with thrombocytopenia because they have a low platelet count, leading to an increased risk of bleeding. Using a small needle minimizes the risk of causing bleeding or bruising during injections. Limiting family visits (choice A) is not directly related to protecting the client from bleeding. Encouraging wheelchair use (choice B) is not specifically relevant to protecting the client with thrombocytopenia. Maintaining accurate fluid intake and output records (choice D) is important but not directly related to preventing bleeding in a client with thrombocytopenia.

Correct Answer: D

Rationale: The correct answer is D because a brain abscess can be caused by direct invasion of the brain, spread of infection by other organs, and spread of infection from nearby sites. Direct invasion can occur from trauma or surgery, while infections from other organs like the lungs or heart can travel through the bloodstream to the brain. Infections from nearby sites such as the sinuses or ears can also spread to the brain. Therefore, all of these mechanisms can lead to the formation of a brain abscess. Choices A, B, and C alone do not encompass all the possible causes of a brain abscess, making D the correct comprehensive answer.

Correct Answer: C

Rationale: The correct answer is C because in cases of suspected spinal injury, it is crucial to keep the spine immobilized to prevent further damage. Rolling Mr. Gabatan onto his abdomen helps protect his spine by maintaining alignment. Placing a pad under his head provides support and covering him with any material available helps maintain his body temperature. Moving him without proper spinal precautions (options A, B, D) could worsen his condition. Seeking additional help is important, but ensuring spinal immobilization comes first. Sitting him up or moving him onto a flat piece of lumber can exacerbate spinal injuries. Therefore, option C is the most appropriate initial action.

Correct Answer: D

Rationale: The correct answer is D: 200 CD4+ cells. In AIDS, the immune system is severely compromised, leading to a decrease in CD4+ T cells. A CD4+ count below 200 cells/mm3 is a key indicator of AIDS, as it signifies advanced immunodeficiency. Choices A, B, and C all have CD4+ cell counts above 200, which would not support the occurrence of AIDS. Therefore, the nurse would evaluate a CD4+ count of 200 cells as laboratory data that support the occurrence of AIDS.

Correct Answer: A

Rationale: The correct answer is A: A complete thyroidectomy also. In the case of a cold nodule, which indicates potential malignancy, a total thyroidectomy is warranted to remove the entire thyroid gland to prevent the spread of cancer. A partial thyroidectomy, as in choices B and C, would not be sufficient in addressing malignancy. Administering thyroid medication, as in choice D, would not be appropriate for treating malignancy. Therefore, the correct approach is to perform a total thyroidectomy to ensure complete removal of the affected gland and to address both hyperthyroidism and potential malignancy.

Correct Answer: C

Rationale: Step 1: The nurse should explain that bladder irrigation is necessary to prevent blood clots from occluding the catheter after a TURP procedure. Step 2: Without irrigation, blood clots could block the catheter, leading to urinary retention and potential complications. Step 3: This explanation addresses the patient's concern about increased pain and highlights the importance of the irrigation in maintaining proper urine flow. Step 4: Choice A is incorrect because the primary purpose of irrigation is not to stop bleeding but to prevent clot formation. Choice B is incorrect because the irrigation is not for administering antibiotics. Choice D is incorrect as it does not address the issue of clot formation.
