Correct Answer: A

Rationale: The correct answer is A: 'Eat high-protein, high-calorie meals.' Individuals with Parkinson's disease benefit from consuming high-protein, high-calorie meals to help maintain muscle mass and energy levels. This dietary modification is important in managing the symptoms of Parkinson's disease. Choice B is incorrect because there is no specific requirement for drinking milk with every meal for individuals with Parkinson's disease. Choice C is incorrect as carbohydrates are also essential for a balanced diet and should not be completely avoided. Choice D is incorrect as carbonated beverages may interfere with the absorption of nutrients from food and are not recommended for individuals with Parkinson's disease.

Correct Answer: C

Rationale: The correct answer is to keep oxygen tanks upright at all times. This is essential for safety as it prevents the tanks from falling and causing injury. Allowing the client to smoke in designated outdoor areas (Choice A) is unsafe as smoking near oxygen equipment can lead to a fire. Placing the oxygen equipment 10 feet away from any open flames (Choice B) is important to prevent fire hazards, but keeping the tanks upright is more directly related to preventing injuries. Restricting fluid intake while using oxygen (Choice D) is not necessary for safety in home oxygen therapy.

Correct Answer: B

Rationale: Administering insulin before meals as prescribed is crucial for a client with diabetes being discharged because it ensures proper blood sugar control. Choice A is incorrect because insulin should not be taken only when feeling unwell; it should be taken as prescribed. Choice C is incorrect as monitoring blood sugar levels weekly may not provide timely adjustments to insulin doses. Choice D is incorrect as checking blood sugar only once in the morning is not sufficient for proper diabetes management.

Correct Answer: A

Rationale: In the case of a patient experiencing acute chest pain, the initial response should include administering prescribed nitroglycerin. Nitroglycerin helps dilate blood vessels and improve blood flow to the heart, which can be beneficial in managing chest pain related to cardiac issues. Providing oxygen can also be helpful to support oxygenation. However, the priority in this scenario is to address the potential cardiac cause by administering nitroglycerin. Calling for emergency assistance is crucial if the patient's condition does not improve or deteriorates. Reassuring the patient is essential for emotional support but should not be the primary intervention in the case of acute chest pain.

Correct Answer: A

Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.
