Which of the following is the best intervention for managing dehydration?

Correct Answer: B

Rationale: The best intervention for managing dehydration is to monitor fluid and electrolyte levels. This approach allows healthcare providers to assess the severity of dehydration, determine appropriate fluid replacement therapy, and prevent complications. Administering antiemetics (Choice A) may help with nausea but does not address the underlying issue of dehydration. Encouraging the client to drink more fluids (Choice C) may be appropriate for mild dehydration but can be inadequate for moderate to severe cases. Administering intravenous fluids (Choice D) is crucial for severe dehydration or cases where oral rehydration is ineffective, but monitoring fluid and electrolyte levels should precede this intervention.

Correct Answer: A

Rationale: The correct answer is A: 'Monitor INR levels and check for bleeding.' When a patient is receiving anticoagulant therapy, nurses must monitor the patient's INR levels to ensure that the anticoagulants are within the therapeutic range and also watch for signs of bleeding, which is a common side effect of anticoagulants. Option B is incorrect because while patient education is important, dietary restrictions are not a direct nursing consideration when administering anticoagulant therapy. Option C is not a specific nursing consideration related to anticoagulant therapy. Option D is incorrect as keeping the patient immobile is not a standard nursing practice for patients on anticoagulant therapy, as mobility is often encouraged to prevent complications like deep vein thrombosis.

Correct Answer: A

Rationale: The correct answer is A: 'Sweating and trembling.' These are classic early signs of hypoglycemia in a diabetic patient. Sweating occurs due to the activation of the sympathetic nervous system in response to low blood sugar levels, while trembling is a result of the body's attempt to increase muscle activity to raise blood sugar levels. Confusion and irritability (Choice B) are more advanced signs of hypoglycemia that occur if the condition is not treated promptly. Dizziness and increased heart rate (Choice C) can also occur but are not as specific and early as sweating and trembling. Nausea and vomiting (Choice D) are more commonly associated with other conditions or severe hypoglycemia, rather than being early signs.

Correct Answer: A

Rationale: The nurse plays a crucial role in preoperative patient care by providing education and ensuring NPO (nothing by mouth) status. This helps prepare the patient for surgery by ensuring they understand the procedure, what to expect, and also by following necessary preoperative fasting guidelines. While obtaining the patient's health history (choice C) is important for overall patient assessment, it is typically done during the preoperative assessment but does not specifically pertain to the nurse's role. Ensuring informed consent (choice B) is primarily the responsibility of the healthcare provider performing the procedure. Confirming the patient's surgical site (choice D) is usually the responsibility of the surgical team and is done immediately before the surgery to prevent errors.

Correct Answer: A

Rationale: The correct side effects of chemotherapy mentioned in this question are nausea and vomiting. These side effects are commonly managed with antiemetics to improve the quality of life for patients undergoing chemotherapy. Choice B (Hair loss and anemia) is incorrect as hair loss and anemia are potential side effects of chemotherapy but are not addressed in this question. Choice C (Diarrhea and fatigue) is also incorrect as it does not match the side effects provided. Choice D (Weight gain and high blood pressure) is inaccurate as these are not typical side effects of chemotherapy.
