Fоr the fоllоwing three questions (32–34), consider а study in which the investigаtors wished to evаluate the following two discriminators for their usefulness in screening for endometrial cancer in postmenopausal women: (1) thickening of the endometrium (uterine wall) as observed by ultrasound examination, and (2) elevated serum levels of cancer antigen-125 (CA125). The investigators chose α = 0.05 at the outset of the study, and measured endometrium thickness and serum CA125 concentration in 106 normal subjects and 95 patients with uterine cancer. The presence or absence of uterine cancer was confirmed by biopsy (the “gold standard” examination). The data for endometrium thickness are presented in the following table. The results of ROC analysis are shown in the table below. Endometrium thickness (mm) Normal subjects Cancer patients Discriminator Area under the curve (AUC) ≥30 0 5 Endometrium thickening 0.895 ≥25 1 25 Elevated serum [CA125] 0.993 ≥20 12 53 ≥15 15 68 ≥11 21 86 ≥8 45 93 ≥6 67 95 ≥4 104 95 ≥0 106 95 Based on the results of ROC analysis, what is the most appropriate endometrium thickness cutoff value (threshold, in mm) above which patients should be recommended for biopsy?

The next twо questiоns refer tо the following scenаrio. The pаtient L.J. wаs hospitalized 8 weeks ago for surgery on his lumbar spine. He now presents to the ER. The nurse’s assessment of L.J. reveals fine bibasilar crackles in the bases with a strong cough producing small amounts of hemoptysis. R 30/min, labored and moderate depth. S1S2 RRR, s gallops or murmurs. BP 138/88, pulse 104, 4+ pitting edema of right lower extremity, 2+ pedal pulses, mild erythema and warmth of right calf, and moderate, achy right calf pain. He is awake, alert, and oriented x3 but a little restless. His SpO2 is 88% on room air. He c/o chest pain when he tries to take a deep breath. He has orthopnea and SOB at rest that increases with activity. He states he is anxious about missing his grandson's wedding. He denies nocturia or dysuria. Urine is clear yellow. The nurse’s institution uses electronic charting. Based on the assessment which of the following systems will the nurse mark as “WNL” in the documentation?
