Correct Answer: B

Rationale: The correct answer is B. Given the family history of diabetes, the initial action the nurse should take is to schedule the patient for a fasting blood glucose level. This will help in assessing if the patient has developed gestational diabetes. Choice A is incorrect because teaching about administering regular insulin is premature without confirming the diagnosis. Choice C is incorrect as an oral glucose tolerance test is typically done earlier in pregnancy. Choice D is incorrect as discussing fetal problems related to gestational diabetes should come after a confirmed diagnosis.

Correct Answer: A

Rationale: The correct answer is A - 'Picketing the employer.' Networking with other professionals, writing letters to legislators, and joining professional organizations are effective ways to apply power and politics in nursing. Picketing the employer is not an appropriate approach in a healthcare setting as it may lead to disruptions in patient care and conflict within the workplace.

Correct Answer: B

Rationale: The correct answer is B, favorable variance. When fewer funds are spent than expected, it indicates efficient budget management, making it a favorable outcome. Choice A, unfavorable variance, is incorrect as it would apply if more money than expected was spent. Choices C and D, dependent variance and independent variance, are unrelated terms in the context of budget variances and do not apply to the situation described.

Correct Answer: C

Rationale: The correct answer is C: Patient autonomy. Patient-centered care focuses on respecting and responding to patient preferences and needs, making patient autonomy a key principle. Choices A, B, and D are incorrect because the patient-centered care model prioritizes the patient's well-being and involvement in decision-making over healthcare provider satisfaction, cost reduction, or provider convenience.

Correct Answer: D

Rationale: The correct answer is D, 'All of the above.' Environmental factors encompass a wide range of influences on decision-making in nursing. Personal preferences can impact how a nurse chooses a course of action, ethical considerations guide decision-making based on moral principles, and the availability of resources determines the options that are feasible. Therefore, all of these factors play a significant role in influencing decision-making in nursing. Choices A, B, and C are incorrect because each of them individually represents a specific environmental factor, whereas the correct answer D acknowledges that all of these factors collectively contribute to influencing decision-making.
