Correct Answer: C

Rationale: Chills and fever are classic signs of an acute hemolytic reaction, where the body is reacting to the transfused blood. This reaction can be life-threatening and requires immediate intervention. Low back pain, distended neck veins, and headache are not typical signs of an acute hemolytic reaction. Low back pain may be associated with kidney issues, distended neck veins with fluid overload or heart failure, and headache with various causes such as stress, dehydration, or migraines.

Correct Answer: A

Rationale: Central cyanosis is best assessed by examining the oral mucosa, as it is a more reliable indicator compared to other areas like the conjunctivae, soles of the feet, and ear lobes. The oral mucosa reflects the oxygen saturation levels of the blood more accurately. Conjunctivae and ear lobes may show cyanosis, but they are not as reliable as the oral mucosa. The soles of the feet are not typically used to assess central cyanosis.

Correct Answer: D

Rationale: The correct instruction for the nurse to provide to a client taking ciprofloxacin for a urinary tract infection is to avoid caffeine. Ciprofloxacin can interact with caffeine, potentially leading to increased side effects or reduced effectiveness. Choice A is incorrect because antibiotics should be taken for the full prescribed course, even if the client starts feeling better. Choice B is incorrect as ciprofloxacin should not be taken with dairy products or antacids as they can interfere with the absorption of the medication.

Correct Answer: D

Rationale: The correct answer is to use a transfer device to lift the client up in bed. This intervention helps reduce friction and the risk of skin breakdown, aiding in the prevention of pressure ulcers. Elevating the head of the bed no more than 45 degrees can help with respiratory issues but does not directly address skin integrity. Applying cornstarch may lead to further skin irritation. Massaging over bony prominences can increase the risk of skin damage rather than maintaining skin integrity.

Correct Answer: B

Rationale: The correct answer is B: Gastrointestinal distress. When taking Lithium Carbonate, clients may experience gastrointestinal distress as an adverse effect. It is crucial to educate clients about this potential side effect to help them manage it effectively. Choices A, C, and D are incorrect. Increased risk of infection (Choice A) is not a typical adverse effect of Lithium Carbonate. Similarly, increased white blood cell count (Choice C) is not associated with this medication's adverse effects. Nausea and vomiting (Choice D) are general side effects of many medications but are not specifically attributed to Lithium Carbonate.
