During one the nurse’s hourly assessments, Ana is lethargic, her respirations are 8/minute and her DTRs are absent. The nurse identifies this as magnesium sulfate toxicity and after informing the obstetrician the following is ordered: stat magnesium level, stop the magnesium infusion, calcium gluconate, 1 gm IVP over 3 mins. One hour later her magnesium level is 7 mg , therapeutic for preeclampsia (4.7 to 8 mg/dl). The nurse evaluates the intervention. The patient has normal CNS functioning; is alert and oriented; respiratory rate is 16; DTR 2+, and urine output 75 mL so the magnesium sulfate is restarted at 1 g/hr per provider order. With the same solution of 40 g/liter, at what rate (mL/hr) would the nurse set the infusion pump?

To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of credits for the course. Suppose a student had these grades: 3.7 in a 5 credit Math course 2.0 in a 2 credit Music course 2.9 in a 5 credit Chemistry course 3.0 in a 5 credit Journalism course What is the student's GPA for that term? Round to two decimal places.

Persons having Raynaud's syndrome are apt to suffer a sudden impairment of blood circulation in fingers and toes. In an experiment to study the extent of this impairment, each subject immersed a forefinger in water and the resulting heat output (cal/cm2/min) was measured. For m = 9 subjects with the syndrome, the average heat output was x = 0.61, and for n = 9 nonsufferers, the average output was 2.09. Let ?1 and ?2 denote the true average heat outputs for the sufferers and nonsufferers, respectively. Assume that the two distributions of heat output are normal with ?1 = 0.3 and ?2 = 0.5. (a) Consider testing H0: ?1 − ?2 = −1.0 versus Ha: ?1 − ?2 < −1.0 at level 0.01. Describe in words what Ha says, and then carry out the test. Ha says that the average heat output for sufferers is the same as that of non-sufferers.Ha says that the average heat output for sufferers is less than 1 cal/cm2/min below that of non-sufferers. Ha says that the average heat output for sufferers is more…

A medical researcher says that less than 79% of adults in a certain country think that healthy children should be required to be vaccinated. In a random sample of 300 adults in that country, 75% think that healthy children should be required to be vaccinated. At α=0.01, is there enough evidence to support the researcher's claim? Complete parts (a) through (e) below.

Children in the United States account directly for $36 billion in sales annually. When their indirectinfluence over product decisions from stereos to vacations is considered, the total economic spendingaffected by children in the United States is $290 billion. It is estimated that by age 10, a child makes anaverage of more than five trips a week to a store . Suppose that you want to prove that children in yourcity average more than five trips a week to a store. Let represent the population mean number of timeschildren in your city make trips to a store. a. State the null and alternative hypotheses. b. Explain the meaning of the Type I and Type II errors in the context of this scenario. c. Suppose that you carry out a similar study in the city in which you live. Based on past studies, youassume that the standard deviation of the number of trips to the store is 1.6. You take a sample of 100children and find that the mean number of trips to the store is 5.47.
