Correct Answer: C

Rationale: Rationale for Correct Answer (C): 1. The newer antihistamines, such as second-generation antihistamines like loratadine or cetirizine, are designed to cause less sedation compared to older antihistamines like diphenhydramine. 2. These newer antihistamines have a lower affinity for crossing the blood-brain barrier, reducing the sedative effects. 3. Therefore, suggesting that the newer antihistamines are different and cause less sedation is the best response to address the patient's concerns. Summary of Incorrect Choices: A. While some newer antihistamines may be combined with decongestants to offset drowsiness, this is not a consistent feature of all newer antihistamines. B. Developing tolerance to sedation after a few months is not a common or reliable response to antihistamines. D. Taking antihistamines at bedtime may help with sedation, but it does not address

Correct Answer: B

Rationale: The correct answer is B: Saturated fat should be limited to less than 7% of total calories. This is because limiting saturated fat intake is crucial in managing type 1 diabetes to reduce the risk of cardiovascular diseases. Saturated fats can worsen insulin resistance and lead to complications. Choice A is incorrect as diabetic management involves more than just insulin. Choice C is incorrect because nonnutritive sweeteners should be used in moderation due to potential side effects. Choice D is incorrect as individuals with diabetes should aim to keep cholesterol intake low to prevent heart problems.

Correct Answer: A

Rationale: The correct answer is A: When the patient is resting. This is because the tremor associated with Parkinson's disease is most noticeable when the patient is at rest due to the characteristic "resting tremor" seen in this condition. The tremor tends to lessen or disappear with purposeful movements or activities, making it more difficult to assess during ambulation, meal preparation, or occupational therapy. By observing the patient at rest, the nurse can accurately assess the presence and severity of the tremor, which is a key diagnostic feature of Parkinson's disease. Other answer choices are incorrect because they do not provide the optimal condition for assessing the tremor associated with Parkinson's disease.

Correct Answer: B

Rationale: The correct answer is B: Administer calcium gluconate. Magnesium sulfate can cause respiratory depression, leading to a low respiratory rate. Calcium gluconate is the antidote for magnesium sulfate toxicity, as it antagonizes the effects of magnesium on the neuromuscular junction. Administering calcium gluconate helps reverse the respiratory depression caused by magnesium sulfate. Increasing IV fluids (Choice A) is not directly related to treating respiratory depression. Vigorously stimulating the patient (Choice C) can exacerbate respiratory depression. Instructing the patient to take deep breaths (Choice D) may not be effective in addressing the underlying cause of respiratory depression due to magnesium sulfate toxicity.
