Refer to the figure below.  In this figure, the allele frequency (p) of an island is on the y-axis, and generational time is on the x-axis.  Each line represents a different migration rate from the mainland.  What can you conclude about how migration rates alter allele frequencies?  Can you determine anything about the mainland population allele frequencies from the graph?

Which of the following genotypic fitness values would result in the most rapid fixation of the beneficial allele, A?

Among the many variations of proteins on the surface of the human red blood cell are those resulting from variation at the MN locus. Two alleles (M and N) and three genotypes (MM, MN, and NN) are distinguished by blood typing. From a sample population of people from Yavin 4 (for all those Star Wars fans out there…), we get the following number of people carrying each genotype: MM = 211, MN = 127, and NN = 17. Is the population in Hardy-Weinberg equilibrium?

A client has been taking isoniazid for a month and a half. The client complains to a nurse about numbness, paresthesia, and tingling in the extremities. The nurse interprets that the client is experiencing which side effect?

If the fitness of one phenotype in the population is a function of the number of individuals of that phenotype as well as the number of individuals of other phenotypes, this may indicate the population is under conditions of __________ selection.

The nurse is preparing a client with multiple sclerosis for discharge from the hospital to home. What instruction is appropriate?

The client who is HIV positive is classified in CDC clinical stage 1, in which persistent lymphadenopathy is present. The client states, “If I progress to stage 2, I will be capable of transmitting the virus to others.” What is the nurse’s best response?

It is decided between Riley and the physician that she will be admitted for inpatient care, as they agree that the withdrawal process may be just beginning.   Riley is taken to the Medical Floor for further care. All the following medications are ordered. The nurse repeats a CIWA-Ar assessment at admission and determines the score is unchanged from the previous assessment.  The most recent blood alcohol concentration was 220 mg/dl. Which order will the nurse implement first? [Option1] due to [Option2]

A nursing student develops a plan of care for a client with multiple sclerosis who has a risk for injury related to spasticity of the leg muscles. The nurse educator reads the plan and should speak to the student about what intervention?

A client with multiple sclerosis lives with her daughter and a three-year-old granddaughter. The daughter asks the nurse what she can do at home to help her mother. The nurse should explain that the client will benefit most from what measure?
