Rationale: The "unfreezing" phase involves preparing staff for change by explaining the necessity and benefits of the change, helping them to understand and accept it.

Correct Answer: A

Rationale: The correct answer is A: Cigarette smoking. Cigarette smoking is a significant risk factor for low birth weight. Smoking during pregnancy reduces the amount of oxygen available to the baby, leading to LBW. Choice B, African American ethnicity, while it may be a risk factor, is not as directly linked to LBW as cigarette smoking. Choice C, poor nutritional status, can contribute to LBW but is not as significant as cigarette smoking in this case. Choice D, limited maternal education, is an important social determinant of health but is not as directly related to LBW as cigarette smoking.

Correct Answer: B

Rationale: After a water deprivation test in a client suspected of having diabetes insipidus, the nurse would expect the urine specific gravity to remain unchanged. This occurs because in diabetes insipidus, the kidneys are unable to concentrate urine, leading to a low urine specific gravity even after water deprivation. Choices A, C, and D are incorrect. Increased edema and weight gain are not typical findings in diabetes insipidus. Rapid protein excretion is not directly related to the condition, and decreased blood potassium is not a common outcome of a water deprivation test for diabetes insipidus.

Correct Answer: A

Rationale: To effectively plan and implement an occupational health program, the nurse needs comprehensive data, including disease trends, birth and death rates, and social environmental conditions. This holistic approach ensures that the program addresses a wide range of health aspects impacting the target population. Option A is the correct choice as it considers multiple factors influencing occupational health. Choices B, C, and D are each individually important but do not provide the breadth of information required to establish priorities in a comprehensive occupational health program.

Correct Answer: C

Rationale: The correct answer is C: Drowsiness. Baclofen, a muscle relaxant commonly used to treat conditions like multiple sclerosis, can cause drowsiness as a side effect. Monitoring for drowsiness is important to ensure the client's safety and well-being. Choice A, Hypertension, is incorrect because baclofen is not known to cause hypertension. Choice B, Muscle spasms, is not a common side effect of baclofen but rather the symptom it is used to treat. Choice D, Tachycardia, is also incorrect as baclofen is not associated with causing an increase in heart rate.
