Correct Answer: D

Rationale: The correct answer is D. A high erythrocyte sedimentation rate (ESR) of 75 mm/hr indicates inflammation, which is common in rheumatoid arthritis. Elevated ESR levels are often seen in inflammatory conditions like rheumatoid arthritis. Options A, B, and C are within the normal range and are not typically indicative of active inflammation associated with rheumatoid arthritis. Therefore, the nurse should report the elevated ESR level to the provider for further evaluation and management.

Correct Answer: D

Rationale: The correct answer is D because it provides the medication (Metoprolol), dosage (5 mg), route of administration (IV), and timing (now), making it a complete prescription. Choices A, B, and C lack either the route of administration or timing, making them incomplete prescriptions. For choice A, it lacks the route of administration, and for choices B and C, they lack the timing of administration.

Correct Answer: A

Rationale: The correct answer is A: Low back pain. Low back pain is a common sign of a hemolytic transfusion reaction, indicating the destruction of red blood cells. This finding requires immediate intervention as it can lead to serious complications such as renal failure. Bradycardia (choice B) is not typically associated with a hemolytic transfusion reaction. Chills (choice C) can be seen in febrile non-hemolytic transfusion reactions. Distended neck veins (choice D) are more indicative of fluid overload rather than a hemolytic reaction.

Correct Answer: C

Rationale: The correct statement to include when teaching a client about furosemide is that it may cause potassium levels to decrease. Furosemide is a loop diuretic that can lead to hypokalemia, emphasizing the importance of monitoring potassium levels. Option A is incorrect because furosemide is usually taken in the morning to prevent nighttime diuresis. Option B is incorrect as tinnitus, not ringing in the ears, is associated with furosemide use. Option D is wrong because while it is essential to monitor potassium levels, the client should be advised to consume foods high in potassium to prevent hypokalemia.

Correct Answer: C

Rationale: The correct answer is C: 'Use a mechanical lift to move a client.' Using a mechanical lift is an essential ergonomic principle to prevent injury and ensure safe client handling. Choice A is incorrect because standing with feet together when lifting a client can lead to instability and improper weight distribution. Choice B is incorrect as raising the client's head of bed before pulling the client up does not primarily relate to ergonomic principles. Choice D is incorrect because while using a gait belt is important for assisting clients with mobility, it is not specifically related to ergonomic principles for safe handling.
