Correct Answer: A

Rationale: Corrected Rationale: Untreated fluid overload can lead to complications such as pulmonary edema and congestive heart failure. Pulmonary edema occurs when excess fluid accumulates in the lungs, leading to difficulty breathing and potentially life-threatening respiratory distress. Congestive heart failure can result from the heart's inability to pump effectively due to the excess fluid volume, leading to symptoms such as fatigue, shortness of breath, and fluid retention. Choices B, C, and D are incorrect because hypertension, liver failure, pulmonary embolism, and dehydration are not the primary complications directly associated with untreated fluid overload.

Correct Answer: B

Rationale: In conscious clients with hypoglycemia, the most appropriate action is to provide a rapidly absorbed carbohydrate source like fruit juice to raise blood glucose levels quickly. Administering glucagon intramuscularly (IM) is usually reserved for unconscious clients or those who are unable to take oral glucose. Providing peanut butter or water would not rapidly address the hypoglycemic state as fruit juice would.

Correct Answer: A

Rationale: The correct answer is A. Taking away a wallet to control spending is a form of financial maltreatment, which is a common form of abuse among older adults. Choices B, C, and D do not indicate maltreatment; rather, they show examples of care and concern from the son. Cooking meals, preventing the older adult from driving alone, and engaging in daily exercise are positive behaviors.

Correct Answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

Correct Answer: A

Rationale: The signs of hypoglycemia include shakiness, confusion, hunger, dizziness, and lightheadedness. However, the classic and most common early sign is shakiness or tremors. When a patient is experiencing hypoglycemia, a healthcare provider should respond promptly by administering glucose to raise the blood sugar levels. Choice A is correct as it directly addresses one of the primary signs of hypoglycemia. Choices B, C, and D are incorrect because while confusion, irritability, hunger, dizziness, and lightheadedness can also be signs of hypoglycemia, shakiness or tremors are the classic and most common early symptoms that healthcare providers should be particularly vigilant for.
