The 68-year-old patient is admitted after 5 days of extremely foul-smelling watery diarrhea with a temperature of 37.9°C, heart rate 118 bpm, and blood pressure 98/52 mmHg. The patient’s recent medical history is significant for being treated 2 weeks ago for a diverticulitis flare-up. Upon assessment, the patient is pale, diaphoretic, and has a tense, distended abdomen that he does not guard with palpation. Lab studies reveal an elevated creatinine (1.9 mg/dL), high white blood cell count (20,000 cells/mL), and normal hemoglobin and hematocrit. The nurse prepares to perform which diagnostic test for this patient?  

An infant of 32 weeks gestation is born precipitously and is noted to be pale and limp. Resuscitative actions are initiated. At one minute of life, the infant has a pinkish central body, bluish hands and feet, a heart rate of 135 bpm, grimaces with painful stimuli, remains limp, and exhibits gasping respiration. Assign an Apgar score to this neonate using a whole number.

The nurse is providing discharge education to the parents of the 7-day-old neonate who required a blood transfusion due to blood loss following circumcision. Which instruction is most important?
