What is the first step in preparing a blood transfusion?

Correct Answer: B

Rationale: The correct first step in preparing a blood transfusion is to verify the client's blood type before starting the transfusion. This step is crucial to ensure compatibility and prevent adverse reactions. Administering the blood via IV push (Choice A) is incorrect as it skips the essential step of verifying the blood type. Warming the blood to body temperature (Choice C) is important but comes after verifying the blood type. Administering diuretics (Choice D) is not part of the preparation process for a blood transfusion.

Correct Answer: B

Rationale: The correct advice to give to a client experiencing constipation is to increase dietary fiber. Dietary fiber helps relieve constipation by promoting regular bowel movements. Encouraging the client to drink water frequently (Choice A) is also important for overall bowel health, but increasing dietary fiber is more directly related to relieving constipation. Administering a laxative (Choice C) should not be the first-line recommendation and should only be considered if dietary and lifestyle changes do not work. Encouraging the client to increase physical activity (Choice D) can be beneficial for overall health but may not directly address the issue of constipation.

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.
