Correct Answer: B

Rationale: The major concern about the health-care system in the United States is the quality of care provided. While disease prevention and collaborative care are important aspects, the primary focus of concern is ensuring that the care delivered meets high standards in terms of effectiveness, safety, and patient outcomes. Reduction in hospital-acquired drug-resistant infections, although relevant, is not the primary concern when evaluating the overall quality of healthcare services.

Correct Answer: B

Rationale: The correct answer is B. Clients taking diuretics are at risk for hyponatremia due to excessive sodium loss. In this scenario, a sodium level of 130 mEq/L indicates hyponatremia, which is commonly associated with diuretic use. Options A, C, and D are not the highest risk factors for developing low sodium levels in this context. Renal failure, hyperaldosteronism, and corticosteroid use are not directly linked to sodium loss as seen with diuretics.

Correct Answer: B

Rationale: The main objective of palliative care is to provide relief from symptoms and improve quality of life. Palliative care focuses on enhancing the quality of life for patients facing serious illnesses by providing relief from symptoms such as pain, stress, and other physical and emotional issues. Choice A is incorrect because palliative care does not aim to cure the disease but rather to manage symptoms. Choice C is incorrect as the goal of palliative care is not to extend hospital stays unnecessarily but to improve the patient's well-being. Choice D is incorrect as palliative care is not solely focused on treatment but takes a holistic approach to care that includes addressing physical, emotional, social, and spiritual needs.

Correct Answer: D

Rationale: Somogyi effect, also known as rebound hyperglycemia, occurs as a response to nighttime hypoglycemia. Eating a protein and carbohydrate snack at bedtime can help prevent this by stabilizing blood sugar levels throughout the night. Instructing the client to take insulin at 2:00 PM each day (Choice A) may not directly address the nighttime hypoglycemia concern. Engaging in physical activity daily (Choice B) is generally beneficial for diabetes management but may not specifically prevent Somogyi's effect. Increasing the dose of regular insulin (Choice C) without addressing the nighttime hypoglycemia issue can exacerbate the problem.

Correct Answer: C

Rationale: The correct answer is C: Biofeedback. Biofeedback is a nonpharmacological technique that uses electronic monitoring equipment to provide real-time data on physiological processes such as heart rate, muscle tension, and skin temperature. Through this feedback, patients learn to control and regulate these bodily functions voluntarily. Choice A, Meditation, involves focusing the mind and reducing stress through techniques like mindfulness or deep breathing, but it does not specifically rely on electronic monitoring equipment. Choice B, Visualization, is a technique where individuals imagine peaceful scenes to promote relaxation and reduce anxiety, and it also does not involve electronic monitoring. Choice D, Chiropractic, is a healthcare profession that focuses on the diagnosis and treatment of musculoskeletal disorders through manual adjustments and manipulation, which is unrelated to the use of electronic monitoring equipment for controlling bodily functions.
