1.护理学基础
答案: A · 体重(千克)除以身高(米)的平方
为什么是这个答案
BMI = 体重(kg)÷ 身高²(m²)。例如,70 kg、1.75 m 约为 22.9 kg/m²。它是一种筛查指标,不能反映身体成分。
答案
A · 体重(千克)除以身高(米)的平方
2.护理学基础
答案: B · Ask the team whether the observations can safely be done less often
为什么是这个答案
Lack of sleep can contribute to delirium. If the patient's scores are stable, the frequency of observations can be reviewed by the team so care is safe but less disruptive.
答案
B · Ask the team whether the observations can safely be done less often
3.临床护理
答案: A · Fluid balance, regular weights and urea, creatinine and electrolytes
为什么是这个答案
IV fluids can cause overload or electrolyte imbalance. Fluid balance charts, weight, clinical assessment and blood tests guide the prescription.
答案
A · Fluid balance, regular weights and urea, creatinine and electrolytes
答案: D · “If I miss a dose, I will take two the next day.”
为什么是这个答案
Doubling a missed warfarin dose raises the risk of bleeding. Patients are taught to follow the prescriber’s instructions for missed doses, and the other statements are correct.
答案
D · “If I miss a dose, I will take two the next day.”
答案: D · Temperature 38.6 °C and heart rate 112/min
为什么是这个答案
SIRS criteria include a temperature above 38 °C or below 36 °C, heart rate above 90/min, respiratory rate above 20/min and a WBC above 12,000 or below 4,000/mm3. Only the first patient meets two.
答案
D · Temperature 38.6 °C and heart rate 112/min
17.实验室检查值与电解质
答案: B · Complete blood count
为什么是这个答案
Hydroxyurea increases fetal hemoglobin and reduces sickling crises, but it can suppress the bone marrow. The CBC, including neutrophils and platelets, is monitored regularly, and doses are adjusted if counts fall.核对依据:Sickle cell disease · MedlinePlus (NIH) (2026)
答案
B · Complete blood count
18.实验室检查值与电解质
答案: C · hCG stimulates the thyroid in early pregnancy
为什么是这个答案
hCG is structurally similar to TSH and stimulates the thyroid, peaking at the end of the first trimester, so TSH often falls slightly. With a normal free T4 and no symptoms, this is usually physiologic and is interpreted with pregnancy-specific ranges.核对依据:TSH (Thyroid-stimulating hormone) Test · MedlinePlus (NIH) (2024)
