Correct Answer: C

Rationale: The correct answer is C: Assessing a client's pain level. This task involves clinical judgment and interpretation, which are within the scope of a licensed nurse's practice. Delegating pain assessment to unlicensed personnel could lead to errors in pain management and inappropriate interventions. Choices A, B, and D involve tasks that can be safely delegated to unlicensed assistive personnel as they do not involve interpretation or nursing judgment. Taking a client's blood pressure, providing oral hygiene, and assisting with ambulation are all routine tasks that can be appropriately assigned to UAP under the supervision of a licensed nurse.

Correct Answer: A

Rationale: Teaching relaxation techniques, such as muscle relaxation, helps the client manage anxiety more effectively. These techniques can be practiced regularly to reduce overall anxiety and can complement prescribed medications. Choice B is incorrect because medication should be taken as prescribed, not only when anxiety is at its worst. Choice C is incorrect as avoiding interactions that trigger stress may not always be feasible and does not teach the client coping mechanisms. Choice D is incorrect as engaging in exercise during anxious periods may not be the most effective strategy for managing moderate anxiety levels.

Correct Answer: A

Rationale: Weight-bearing exercises are crucial in managing osteoporosis as they help strengthen bones. Choice A is the correct answer because weight-bearing activities, such as walking, dancing, or weight training, help stimulate bone formation and strengthen bones, which is essential in managing osteoporosis. Choice B is incorrect as the primary focus should be on the type of exercise rather than weight reduction. Choice C is incorrect because avoiding exercise altogether can lead to further bone density loss, and it is important to engage in safe weight-bearing activities. Choice D is incorrect as the primary goal of exercise in osteoporosis is to improve bone density through weight-bearing activities.

Correct Answer: A

Rationale: The correct answer is to increase the dose of levothyroxine. In hypothyroidism, the body does not produce enough thyroid hormone, leading to symptoms like lethargy and cold intolerance. Increasing the dose of levothyroxine, which is a synthetic thyroid hormone replacement, helps correct the deficiency and alleviates the symptoms. Choice B, administering antipyretic medication, is incorrect as antipyretics are used to reduce fever, not treat hypothyroidism symptoms. Choice C, providing a warm blanket and increasing room temperature, may provide temporary comfort but does not address the underlying hormonal deficiency. Choice D, increasing fluid intake, is important for overall health but does not directly address the symptoms of hypothyroidism.

Correct Answer: C

Rationale: Elevated blood pressure is a significant risk factor for coronary artery disease because it increases the strain on the arteries, leading to potential damage and a higher risk of developing coronary artery disease. Elevated HDL cholesterol (Choice A) is actually considered beneficial as it helps reduce the risk of heart disease. Low LDL cholesterol (Choice B) is also beneficial as high levels of LDL are associated with an increased risk of coronary artery disease. Low triglyceride levels (Choice D) are not typically considered a major risk factor for coronary artery disease.
