Correct Answer: B

Rationale: The correct answer is to monitor electrolyte levels frequently. When a client is dehydrated and needs fluids, it is essential to monitor electrolyte levels to prevent complications such as electrolyte imbalances. Administering antiemetics to prevent vomiting (Choice A) may be necessary but is not the priority when addressing dehydration. Administering oral rehydration solutions (Choice C) can be beneficial, but monitoring electrolyte levels takes precedence to ensure proper hydration. Inserting an NG tube for fluid administration (Choice D) is invasive and not typically the first-line approach for managing dehydration.

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 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.

Correct Answer: A

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with chest pain because it helps relieve chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Assessing pain level, monitoring vital signs, and providing oxygen therapy are important interventions as well, but administering nitroglycerin takes precedence in addressing the immediate symptom of chest pain and potential cardiac ischemia.

Correct Answer: A

Rationale: The correct procedure for taking a telephone order from a provider is to state the patient's name, drug, dose, route, frequency, and then read back the order to ensure accuracy. This process helps in preventing errors and ensures that all relevant information is correctly documented. Choice B is incorrect because having a witness listen to the order is not a standard practice and may not guarantee accuracy. Choice C is incorrect as verifying the order within 12 hours may lead to delays in patient care. Choice D is incorrect because waiting for the provider to verify the order during the next in-person visit could result in a significant delay in administering necessary medication.
