Correct Answer: A

Rationale: The correct answer is A: Basophils. Basophils are a type of white blood cell that release histamine during allergic reactions. They contain granules filled with histamine, which is released when they encounter an allergen. Monocytes, eosinophils, and neutrophils do not release histamine during allergic reactions. Monocytes are involved in immune response and inflammation, eosinophils are responsible for combating parasitic infections, and neutrophils are primarily involved in fighting bacterial infections.

Correct Answer: C

Rationale: The rule of nines is a method used to estimate the extent of burns on a patient's body. According to this rule, each major body part is assigned a percentage value that represents the total body surface area (TBSA). In this case, Mr. Kawasaki has second-degree burns on his right leg and arm (9% each) and left leg (9%) and third-degree burns on his left arm (9%). Adding these percentages together, we get a total of 36%, which corresponds to the extent of burn on Mr. Kawasaki's body. Choice A (18%) is incorrect because it only considers one arm and one leg, neglecting the other affected areas. Choice B (45%) is incorrect as it overestimates the extent of burns by including additional body parts not affected. Choice D (54%) is also incorrect as it includes more body parts than those actually burned. Therefore, the correct answer is C (36%) as it accurately reflects the distribution of burns based

Correct Answer: A

Rationale: The correct answer is A: Painless hematuria. This is an early indicator of bladder cancer because blood in the urine without pain is a common symptom in the early stages of the disease. Nocturia (B), frequent urination at night, is more commonly associated with urinary tract infections or benign prostatic hyperplasia. Occasional polyuria (C), excessive urination, can be a symptom of diabetes or kidney disease. Dysuria (D), painful urination, is more indicative of urinary tract infections or urethritis. Therefore, painless hematuria is the most specific early indicator of bladder cancer among the choices provided.

Correct Answer: D

Rationale: The correct answer is D (3750ml) because the client will receive 1000ml D5W + 500ml normal saline + 1500ml D5NS + 50ml antibiotic every 8 hours x 3 times in 24 hours (50ml x 3 = 150ml). Adding these together gives a total of 1000ml + 500ml + 1500ml + 150ml = 3150ml. Therefore, the client's IV fluid intake for 24 hours will be 3150ml.

Correct Answer: B

Rationale: The correct answer is B because having the patient rate her fatigue on a scale allows for a subjective assessment directly from the patient, providing valuable insight into the severity and impact of fatigue on her daily life. This approach considers the patient's perspective, which is crucial in understanding her experience and tailoring interventions. Choice A (observing activity level) may not accurately capture the subjective experience of fatigue. Choice C (monitoring vital signs) does not directly assess fatigue but rather general health status. Choice D (monitoring hemoglobin and hematocrit values) can indicate anemia but may not fully capture the patient's fatigue experience.
