Correct Answer: B

Rationale: When caring for a client with heart failure on fluid restriction, weighing the client daily is crucial to monitor fluid balance accurately. This helps healthcare providers assess if the client is retaining excess fluids, which can worsen heart failure. Encouraging the client to drink more fluids (choice A) contradicts the goal of fluid restriction. Limiting intake of fruits and vegetables (choice C) is not a specific guideline for managing fluid restriction in heart failure. Monitoring fluid intake only during meals (choice D) is insufficient as fluid balance needs to be monitored consistently throughout the day.

Correct Answer: B

Rationale: Clear fluid draining from the ear can indicate cerebrospinal fluid leakage, which is a serious concern after a head injury. This leakage can signify a skull fracture or damage to the meninges, potentially leading to infection. Therefore, it should be reported immediately for further evaluation and management. Choices A, C, and D are typical findings after head trauma and are not as urgent as the presence of clear fluid draining from the ear.

Correct Answer: B

Rationale: The correct answer is B, Hypokalemia. Furosemide is a loop diuretic that works by increasing the excretion of water and electrolytes, including potassium, leading to hypokalemia. Choice A, Bradycardia, is incorrect because furosemide does not typically cause a decrease in heart rate. Choice C, Increased blood pressure, is incorrect as furosemide is actually used to lower blood pressure by reducing fluid volume. Choice D, Increased urine output, is a common effect of furosemide due to its diuretic action but is not an adverse side effect.

Correct Answer: A

Rationale: Correct Answer: A. When assessing a patient with a potential myocardial infarction, it is crucial to assess symptoms, monitor vital signs like blood pressure and heart rate, and order an electrocardiogram (ECG) to evaluate for cardiac abnormalities. Choice B is incorrect because administering medications should be based on the findings of the assessment and diagnostic tests, not administered indiscriminately. Choice C is incorrect because the administration of thrombolytics and oxygen therapy should be based on specific criteria and should be done in a controlled setting. Choice D is incorrect as educating the patient on lifestyle changes is important for prevention but is not the immediate priority when managing a potential myocardial infarction.

Correct Answer: B

Rationale: The most important point to emphasize when teaching a client with diabetes about insulin administration is to administer insulin before meals as prescribed. This is crucial for maintaining proper blood sugar control throughout the day. Choice A is incorrect because blood sugar levels need to be monitored multiple times a day, not just once in the morning. Choice C is incorrect because insulin should be administered according to the prescribed schedule, not only when feeling unwell. Choice D is incorrect because blood sugar monitoring should be done at various times during the day, not just in the evening.
