Correct Answer: C

Rationale: The correct answer is C. Discarding leftovers after 48 hours is not an effective recommendation to prevent foodborne illnesses. Leftovers should actually be discarded within 2 hours if they have been at room temperature. Choices A, B, and D are all effective strategies to prevent foodborne illnesses: avoiding unpasteurized dairy products reduces the risk of harmful bacteria, keeping cold food temperatures below 4.4°C (40°F) inhibits bacterial growth, and washing raw vegetables thoroughly removes contaminants.

Correct Answer: B

Rationale: When the high-pressure alarm on a ventilator goes off, the nurse's initial action should be to perform a quick assessment of the client's condition. This assessment helps in promptly identifying the cause of the alarm, such as mucus plugging, kinking of the tubing, or other issues. By assessing the client first, the nurse can determine the appropriate intervention needed to address the alarm. Choices A and D are incorrect because disconnecting the client from the ventilator or pressing the alarm reset button should not be the initial actions without assessing the client's condition. While calling the respiratory therapist for help could be beneficial, assessing the client's condition should be the nurse's priority to address the immediate concern.

Correct Answer: B

Rationale: The correct answer is B: 1 medium orange. Oranges are well-known for being rich in vitamin C, an essential nutrient for immune function and skin health. While choices A, C, and D also contain some vitamin C, the medium orange provides a higher amount of this vitamin compared to a ½ cup of green pepper, ½ cup of cabbage, or a medium tomato.

Correct Answer: D

Rationale: The correct answer is D, Pickled beets. Pickled foods often contain high levels of sodium, which should be avoided in a low-sodium diet. Boiled rice, Italian bread, and broiled salmon filet are generally lower in sodium compared to pickled beets, making them more suitable choices for a client on a low-sodium diet.

Correct Answer: B

Rationale: The correct answer is B. In diabetes management, complex carbohydrates should constitute the largest portion of the diet as they help in maintaining steady energy levels and managing blood sugar. Choice A is incorrect because a high-fat diet can lead to complications in diabetes. Choice C is incorrect as simple sugars can cause rapid spikes in blood sugar levels. Choice D is incorrect as protein, while important, should not be the main source of calories for a diabetic individual.
