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: Glucocorticoids and androgens. The adrenal cortex is divided into three layers, with the outer layer responsible for producing mineralocorticoids like aldosterone, the middle layer producing glucocorticoids like cortisol, and the inner layer producing androgens. Glucocorticoids are essential for regulating metabolism and immune response, while androgens are male sex hormones. Choices B, C, and D are incorrect because mineralocorticoids, catecholamines, norepinephrine, and epinephrine are produced by different parts of the adrenal gland, not specifically by the adrenal cortex.

Correct Answer: C

Rationale: Subjective data are information reported by the patient that cannot be measured or observed directly. In this case, nausea and abdominal pain are symptoms that can only be described by the patient, making them subjective data. Vomiting, pulse rate, respirations, blood pressure, pale skin, and thick toenails are all objective data, as they can be measured or observed directly by the healthcare provider. Therefore, choice C is the correct answer as it represents subjective data.

Correct Answer: C

Rationale: The correct answer is C: Confusion. Hypernatremia is an electrolyte imbalance characterized by high sodium levels in the blood. Confusion is a common symptom as high sodium levels can affect brain function. Dry skin (A) is more indicative of dehydration, tachycardia (B) is a symptom of various conditions, and pale coloring (D) is not specific to hypernatremia. Confusion is a key indicator that the nurse should assess for when monitoring for hypernatremia.

Correct Answer: C

Rationale: The correct answer is C: Obesity. Obesity is a known risk factor for colon cancer as it can lead to chronic inflammation and changes in hormone levels, increasing the risk of developing cancerous cells in the colon. Smoking (choice A) is more strongly associated with lung cancer. Heavy alcohol consumption (choice B) is linked to increased risk of liver and esophageal cancer, not colon cancer. Saccharin consumption (choice D) has not been definitively linked to colon cancer. In summary, obesity is the most relevant risk factor for colon cancer among the choices provided.
