Correct Answer: A

Rationale: The correct answer is A: Potential for infection. The decreased WBC count indicates reduced ability to fight off infections, making this the priority nursing diagnosis. Normal RBC count rules out anemia-related complications. Decreased HCT and Hgb indicate possible anemia but do not directly relate to infection risk. Choices B and C are not as critical as the potential for infection due to the significant impact on the individual's health and well-being. Choice D, fluid volume excess, is not directly related to the blood test results provided.

Correct Answer: C

Rationale: The correct answer is C: fat embolism syndrome related to femur fracture. Fat embolism syndrome occurs when fat globules enter the bloodstream and travel to the lungs, causing respiratory distress. In this case, the patient's femur fracture likely led to fat embolism, explaining her dyspnea, tachypnea, crackles, and thick sputum. Choices A, B, and D do not align with the patient's presentation and history, making them incorrect. Choice A suggests smoke inhalation, which is not supported by the scenario. Choice B mentions pneumonia from bedrest, which is not a common complication of immobility. Choice D proposes hypovolemic shock from multiple trauma, which does not explain the respiratory symptoms and sputum production observed in the patient.

Correct Answer: A

Rationale: The correct answer is A: Type A. Individuals with blood type A have a slightly higher risk of developing gastric cancer compared to other blood types. This is due to the presence of certain antigens associated with Type A blood that may increase susceptibility to gastric cancer. In this case, the nurse mentions a 10% increased risk for individuals with Type A blood, which aligns with the known epidemiological data. Choice B: Type AB is incorrect because individuals with Type AB blood do not have a known increased risk of gastric cancer. Choice C: Type B is incorrect because individuals with Type B blood do not have a known increased risk of gastric cancer. Choice D: Type O is incorrect because individuals with Type O blood actually have a slightly lower risk of developing gastric cancer compared to individuals with Type A blood.

Correct Answer: D

Rationale: The correct answer is D because the absence of skin breakdown indicates that the turning schedule was effective in preventing pressure ulcers. Skin breakdown is a key indicator of pressure ulcer development, so its absence suggests that the patient's skin integrity was maintained. Choice A is incorrect because documentation alone does not guarantee successful prevention. Choice B is incorrect as redness on the heels can still indicate the early stages of pressure ulcers. Choice C is unrelated to skin integrity and pressure ulcer prevention.

Correct Answer: B

Rationale: The correct answer is B: Stage 2 hypertension. The patient's BP readings consistently fall within the range of 160-179 systolic or 100-109 diastolic, which aligns with the criteria for Stage 2 hypertension based on the current guidelines. This classification indicates a higher level of hypertension that requires prompt medical attention and intervention to reduce the risk of complications. Choices A, C, and D are incorrect because they do not correspond to the BP readings provided, falling outside the range for prehypertension, Stage 1 hypertension, and posthypertension.
