A client with hypertension is being taught about the DASH diet. Which of the following statements by the client indicates an understanding of the teaching?

Correct Answer: C

Rationale: The correct answer is C. The Dietary Approaches to Stop Hypertension (DASH) diet is recommended for managing hypertension. Increasing the intake of fruits and vegetables is a key component of the DASH diet as these foods are rich in nutrients that can help lower blood pressure levels. Choices A, B, and D are incorrect because they go against the principles of the DASH diet, which focuses on reducing sodium intake, increasing potassium-rich foods, and consuming whole grains.

Correct Answer: B

Rationale: The correct answer is B. Decreasing the intake of high-fat foods is essential in managing pancreatitis as high-fat foods can exacerbate symptoms and lead to complications. By reducing high-fat foods in their diet, the client demonstrates an understanding of the dietary management needed for pancreatitis. Choices A, C, and D are incorrect. Increasing high-fat foods (Choice A) is not recommended for pancreatitis as it can worsen the condition. While high-protein foods (Choice C) can be beneficial in some cases, the primary focus in pancreatitis management is on reducing fat intake. Decreasing high-protein foods (Choice D) is not a key dietary management approach for pancreatitis.

Correct Answer: B

Rationale: Correct! Hyperkalemia is a condition characterized by high levels of potassium in the blood. To manage hyperkalemia, it is essential to decrease the intake of potassium-rich foods since excess potassium can worsen the condition. By understanding the need to decrease potassium-rich foods, the client shows comprehension of the dietary management required for hyperkalemia. Choice A is incorrect because increasing potassium-rich foods would exacerbate hyperkalemia. Choice C is incorrect since increasing sodium-rich foods is unrelated to managing hyperkalemia and could potentially lead to other health issues. Choice D is incorrect as decreasing sodium-rich foods is not the primary focus when managing hyperkalemia.

Correct Answer: A

Rationale: Sterilization of culture media is critical in microbiology to eliminate contaminants. Autoclaving (choice A) uses moist heat under pressure (typically 121°C at 15 psi for 15-20 minutes) to kill bacteria, spores, and viruses, making it the gold standard for sterilizing liquid media like agar or broth. Boiling (choice B) at 100°C can kill vegetative bacteria but not heat-resistant spores, rendering it inadequate for complete sterilization. Hot air oven (choice C) employs dry heat (160-170°C for 2 hours) and is suitable for glassware, not liquid media, as it may evaporate or degrade nutrients. Ionizing radiation (choice D) is effective for heat-sensitive materials (e.g., plastics), but it's less common for routine media preparation due to cost and equipment needs. Autoclaving is the correct answer (A) because it ensures thorough sterilization of culture media, a process nurses and lab personnel rely on to maintain aseptic conditions for accurate diagnostic cultures.

Correct Answer: B

Rationale: Renal carcinoma (e.g., renal cell carcinoma) often presents insidiously. Dysuria (choice A) suggests infection, not cancer. Painless hematuria (choice B) is classic, as tumors bleed into urine without early pain, often the first sign. Urgency (choice C) relates to bladder issues, not renal tumors. Erythema (choice D) is skin redness, unrelated. B is correct, reflecting renal carcinoma's hallmark. Nurses educate on reporting hematuria, monitor for flank pain or mass (later signs), and support diagnostic imaging, aiding early detection.
