A patient is prescribed amoxicillin three times a day. The correct abbreviation for this frequency is: 

A patient with type 2 diabetes is prescribed a sliding scale for insulin administration. The sliding scale orders are as follows: Blood glucose 150-199 mg/dL: 2 units Regular insulin Blood glucose 200-249 mg/dL: 4 units Regular insulin Blood glucose 250-299 mg/dL: 6 units Regular insulin Blood glucose 300-349 mg/dL: 8 units Regular insulin Blood glucose 350-399 mg/dL: 10 units Regular insulin The patient is also prescribed 20 units of NPH insulin to be administered every morning. The patient’s blood glucose level before breakfast is 275 mg/dL. How many total units of insulin should the nurse administer?

A nurse is ordered to administer 1000 mL of normal saline (N/S) over 12 hours. How many milliliters (mL) per hour should the nurse set the IV pump to deliver?

Which statement about the scientific method is true?

Which of the following describes the individual with the highest evolutionary fitness?

The color of a certain species of beetle is determined by a single gene. Two beetles homozygous for green coloration (meaning they have two copies of the green allele) produce a single offspring with brown coloration. Brown color must have appeared in this offspring as a result of

Because natural populations tend to produce more individuals than can be supported by the environment, individuals must compete for resources.  Some individuals are better competitors than others, meaning that not all individuals will survive.  In turn, some individuals will have higher fitness than others. This describes:

A zombie apocalypse wipes out almost the entire human species before the zombie threat is eliminated. Only a group of 100 people who were at a family reunion on an uninhabited island survived. They returned to the mainland completely unaware of what had happened to everyone. Which of the following processes is most likely to occur in this small population of humans?

A population of 8,250 mice occupies the sand dunes in a coastal area. A severe hurricane washes out several miles of sand dunes. As a result, only 50 mice remain. The population has experienced:

Albinism is a recessive disorder in which the skin and hair fail to produce pigment. The following question(s) ask you to evaluate the pedigree chart shown here in which “N” is the allele for normal pigmentation and “n” is the allele for albinism. The shaded circles for Deirdre and Shannon represent the only individuals expressing the disorder.   What is Geoff’s genotype?
