Correct Answer: B

Rationale: The correct answer is Novolin R (Regular insulin). Regular insulin is used for continuous infusion to treat diabetic ketoacidosis due to its rapid onset of action. Novolin L (Intermediate-acting insulin) (choice A), Novolin N (Intermediate-acting insulin) (choice C), and Novolin U (Ultra-Long-acting insulin) (choice D) are not suitable for continuous infusion in the treatment of diabetic ketoacidosis.

Correct Answer: C

Rationale: The correct answer is C: 'It is a circular process of continued nursing care.' The four-step method of assessment, planning, implementation, and evaluation in nursing is a continuous and cyclical process. Choice A is incorrect because the method is not solely problem-focused; it involves a comprehensive approach. Choice B is incorrect as it does not capture the cyclical nature of the process. Choice D is incorrect as the method is systematic and not based on trial-and-error but rather evidence-based practice.

Correct Answer: D

Rationale: The correct question for the nurse to ask the male client diagnosed with aorto-iliac disease during the admission interview is about any problems experienced during sexual intercourse. Aorto-iliac disease can lead to impaired blood flow to the pelvis and lower extremities, affecting sexual function. Therefore, it is essential to assess the client's sexual health in such cases. The other options, such as sitting for long periods of time, bowel movements and urination frequency, and throbbing sensation when lying down, are not directly related to the potential impact of aorto-iliac disease on sexual function. Hence, they are not the most pertinent questions to ask during the admission interview.

Correct Answer: B

Rationale: When collecting a stool specimen, the nurse should usually take about 1 inch of the specimen or a teaspoonful for testing purposes. This amount is sufficient for laboratory analysis and helps ensure accurate results. It is important for the nurse to follow the proper procedure for specimen collection to maintain accuracy in diagnostic testing.

Correct Answer: C

Rationale: The correct answer is C. Eating three eggs daily increases cholesterol intake, which could exacerbate atherosclerosis. Omega-3 supplements, cooking with canola oil, and flavoring meat with lemon juice do not significantly impact cholesterol levels compared to consuming three eggs daily. Therefore, the nurse should focus on educating the client to reduce egg consumption to improve cholesterol levels.
