Correct Answer: A

Rationale: The correct answer is A: Hyperkalemia. In acute Addisonian crisis, the adrenal glands do not produce enough cortisol and aldosterone, leading to electrolyte imbalances. This results in increased potassium levels (hyperkalemia) due to lack of aldosterone to promote potassium excretion. Hypernatremia (choice B) is less likely as aldosterone deficiency leads to sodium loss. Reduced BUN (choice C) is unlikely as Addison's crisis does not directly affect urea levels. Hyperglycemia (choice D) is not typically seen in Addisonian crisis as cortisol deficiency usually results in hypoglycemia.

Correct Answer: C

Rationale: The correct answer is C: A decreased number of functioning acetyl-choline receptor sites. This is because in diseases like myasthenia gravis, there is an autoimmune attack on acetylcholine receptor sites, leading to decreased functionality. Choice A is incorrect because it refers to a genetic defect in acetylcholine production, which is not typically the cause of myasthenia gravis. Choice B is incorrect as it suggests a reduced amount of acetylcholine, which is not the primary issue in myasthenia gravis. Choice D is incorrect as it mentions inhibition of the enzyme Ache, which is not the main mechanism in this disease.

Correct Answer: B

Rationale: The correct answer is B: A latex condom with spermicide provides the best protection against HIV transmission during sexual intercourse. Rationale: 1. Latex condoms create a physical barrier that helps prevent the exchange of bodily fluids containing HIV. 2. Spermicide can further reduce the risk of HIV transmission by killing some viruses and bacteria. 3. Research shows that consistent and correct use of condoms is highly effective in reducing the risk of HIV transmission. 4. Other choices are incorrect: - A: Unprotected sex between HIV-positive individuals can lead to the transmission of drug-resistant strains or different strains of HIV. - C: Contraceptive methods like birth control pills do not protect against HIV transmission. - D: The intrauterine device is not specifically recommended for clients with HIV due to potential risks of infection.

Correct Answer: B

Rationale: The correct answer is B because using a PICOT question involves formulating a research question to guide evidence-based practice. B indicates the nurse is implementing interventions based on scientific research, aligning with the PICOT framework (Patient, Intervention, Comparison, Outcome, Timeframe). This approach ensures that care decisions are supported by the best available evidence, leading to improved patient outcomes. Choice A is incorrect because practicing nursing based on court evidence does not align with the PICOT framework. Choice C is incorrect as using standardized care plans for all patients may not consider individual patient needs and preferences as required in a PICOT question. Choice D is incorrect as planning care based on tradition does not involve integrating current research evidence as in the PICOT approach.

Correct Answer: A

Rationale: The correct answer is A: Liver. The liver is a common site for metastasis because it receives blood from various organs, making it a prime location for cancer cells to travel and establish secondary tumors. Additionally, the liver has a rich blood supply and provides a favorable environment for cancer cells to thrive. In contrast, B (Reproductive tract) and C (Colon) are not as common sites for metastasis compared to the liver. Choice D (White blood cells) is incorrect as metastasis involves the spread of cancer cells to distant organs, not within the blood cells themselves.
