A nurse is caring for a client who has anemia. Select the 4 findings that require immediate follow-up (Select all that apply).    Laboratory Results 0900:   Hct 26% (37% to 47%) Hgb 8 g/dL (12 to 16 g/dL) WBC count 7,500/mm3 (5,000 to 10,000/mm3) Potassium 4.2 mEq/L (3.5 to 5 mEq/L)   Nurses’ Notes 1000: One unit of packed RBCs started through an 18-gauge IV in the client’s left hand. Unit of blood infusing well. IV site dry and intact, without redness or swelling.   1015: Client is flushed and reports new onset of flank back pain and chills. Client voided 250 mL of reddish-brown urine. Bilateral breath sounds clear and present throughout. IV site dry and intact, without redness or swelling.     Vital Signs 1000: Temperature 36.8° C (98.2° F) Blood pressure 106/66 mm Hg Heart rate 108/min Respiratory rate 22/min Oxygen saturation 97% on room air   1015: Temperature 39.6° C (103.3° F) Blood pressure 78/50 mm Hg Heart rate 122/min Respiratory rate 28/min Oxygen saturation 95% on room air

A graduate nurse who has been recently hired at a local hospital is completing an application for a nursing license. Which of the following information is a requirement for the nurse during the initial licensure process? Select all that apply. 

In a newly discovered species of reptile, a geneticist notices that all individual organisms that produce large, nutrient-rich eggs possess a heterogametic sex chromosome pair (ZW), while the individuals that produce small, motile sperm possess a homogametic sex chromosome pair (ZZ). If a harmful recessive mutation is linked to the Z chromosome, which demographic of this species will express the mutant phenotype more frequently across a population?

In Labrador Retrievers, coat color is governed by two interacting loci. Locus B determines pigment density (Black B is dominant to Brown b). Locus E acts as the control switch for pigment deposition in the hair follicle. If a dog inherits the homozygous recessive genotype $ee$, no dark pigment can be deposited in the fur, defaulting the coat to a yellow color regardless of the alleles at the B locus. If you cross a black lab (BbEe) with a brown lab (bbEe), what proportion of the resulting litter will be yellow puppies?

A botanist isolates a mutant strain of Arabidopsis thaliana with curly leaves. She discovers that the phenotype is driven by an allele that produces an unstable structural protein. The plant’s genotype is designated as C1C2. Structurally, C1 produces the wild-type stable protein, while C2 produces the faulty, unstable version. Because the presence of even a single wild-type allele provides enough structural stability to yield flat leaves, the C1C2 plant exhibits perfectly flat leaves. Which of the following correctly pairs the classification of this genotype with the underlying behavioral nature of the C2 allele?

A remote, closed community exhibits an unusually high frequency of a rare, debilitating autosomal recessive skin condition. When a population geneticist maps out the community’s lineages, they note a frequent occurrence of double horizontal lines connecting mating partners.   Part A: Identify what specific biological event these double horizontal lines represent, and explain what this means regarding the shared ancestry of the parents. Part B: Explain the underlying genetic mechanism at play here. Why does this specific mating pattern drastically increase the statistical probability that a rare autosomal recessive condition will manifest in the children, even if both parents are completely healthy and asymptomatic?
