Correct Answer: C

Rationale: Exercising at least five times a week is recommended to meet the goals of planned exercise for diabetic clients. This frequency helps in managing blood sugar levels effectively and improving overall health. Exercising once a week (Choice A) may not provide sufficient benefits or consistency required for diabetic clients. Exercising three times a week (Choice B) is better but may still fall short of the recommended frequency for optimal outcomes. Exercising every day (Choice D) may lead to burnout or overtraining if not properly balanced with rest days, which could be counterproductive for diabetic clients.

Correct Answer: D

Rationale: Decreased central venous pressure (CVP) is the correct assessment finding in a client with deficient fluid volume. This is because a decrease in CVP indicates reduced blood volume returning to the heart, which is consistent with hypovolemia. Lung congestion (Choice A) would be more indicative of fluid volume excess, not deficiency. Decreased hematocrit (Choice B) may be seen in conditions such as anemia but is not specific to deficient fluid volume. Increased blood pressure (Choice C) is not typically associated with deficient fluid volume; in fact, hypovolemia often leads to decreased blood pressure.

Correct Answer: A

Rationale: The client with hyperthyroidism should avoid foods high in iodine, as it can exacerbate the condition by increasing thyroid hormone production. Seafood, particularly ocean fish, is rich in iodine, making it a food to avoid. Spinach, bananas, and oatmeal do not contain high levels of iodine and are generally safe for individuals with hyperthyroidism.

Correct Answer: C

Rationale: The correct nursing intervention for a male client with SIADH is to restrict fluids. In SIADH, there is excess release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. Restricting fluids helps prevent further dilutional hyponatremia by reducing water intake. Infusing I.V. fluids rapidly (choice A) would worsen the condition by adding more fluids, encouraging increased oral intake (choice B) is contraindicated as it adds more fluids, and administering glucose-containing I.V. fluids (choice D) is not a standard treatment for SIADH.

Correct Answer: D

Rationale: The correct answer is D. Ethical principles can influence the creation of laws but are not equivalent to laws themselves. Laws are established by governing bodies to provide a framework for society, whereas ethical principles guide individuals' moral conduct. Choice A is incorrect because governments enforce laws, not ethics. Choice B is incorrect as laws set legal standards rather than ethical ones. Choice C is incorrect because ethics are principles that guide behavior but are not necessarily highly specific.
