Correct Answer: C

Rationale: The correct answer is C: 'Cut toenails straight across.' This instruction is crucial for clients with diabetes to prevent ingrown toenails and potential foot complications. Soaking feet in hot water daily (Choice A) can lead to skin damage and is not recommended for diabetic individuals. Using a heating pad on the feet daily (Choice B) can cause burns or injuries due to reduced sensation in the feet that often accompanies diabetes. Massaging feet with lotion daily (Choice D) is generally safe but may not address the specific preventive measure of cutting toenails correctly.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen and provide breathing exercises. These interventions are essential in managing COPD as they help improve lung function and oxygenation. Choice B is incorrect as suctioning airway secretions and encouraging coughing are not typically indicated for COPD patients. Choice C is incorrect as while administering bronchodilators is common in COPD treatment, monitoring oxygen saturation alone is not a comprehensive intervention. Choice D is incorrect as restricting fluids is not a standard intervention for COPD, and encouraging mobility, although beneficial, is not as directly related to managing COPD symptoms as administering oxygen and providing breathing exercises.

Correct Answer: D

Rationale: The correct answer is D: American Diabetes Association. The American Diabetes Association is a reputable source that provides credible information on managing diabetes. While family members can offer support, they may not have the specialized knowledge on oral antidiabetic agents. Pharmacists are knowledgeable about medications but may not provide comprehensive information on diabetes management. Dietitians can offer valuable advice on nutrition but may not cover specific details about oral antidiabetic agents. Therefore, referring the client to the American Diabetes Association ensures access to accurate and detailed information related to their condition.

Correct Answer: B

Rationale: The correct answer is B. A 19-year-old with a fever of 103.8°F who is confused and unable to orient to place and time likely has a severe infection or a serious medical condition affecting the central nervous system. This client needs immediate attention as altered mental status combined with a high fever can indicate a life-threatening situation. Choices A, C, and D present important conditions that require medical care, but they are not as urgent as the 19-year-old with a high fever and confusion. The 12-year-old with a laceration may require treatment for bleeding and a tetanus shot, the 49-year-old with a compound fracture needs urgent orthopedic intervention, and the 65-year-old with a high blood sugar is concerning for hyperglycemia but can wait momentarily compared to the client with a fever and altered mental status.

Correct Answer: A

Rationale: To administer a total of 300 mg daily (150 mg PO BID), the nurse should give 20 mL of the syrup. This is calculated by dividing the total daily dose (300 mg) by the concentration of the syrup (15 mg/mL), which equals 20 mL. Choice B (15 mL), C (25 mL), and D (10 mL) are incorrect because they do not accurately calculate the required volume of syrup needed to deliver the prescribed dose.
