What do the following 3 antibiotic classes have in common: metronidazole, aminoglycosides, tetracycline?

A nurse is reviewing the chart of a patient newly prescribed valsartan for management of hypertension. Which of the following assessment findings requires immediate follow-up before administering the first dose?

A nurse in the emergency department is assessing a 68-year-old client with a suspected diagnosis of community-acquired pneumonia (CAP). The client reports productive cough, fatigue, and dyspnea for the past 3 days. The following findings are documented: Confused to time and placeBP: 88/56 mmHgRR: 32/minBUN: 28 mg/dLTemperature: 100.8°F (38.2°C)O₂ saturation: 91% on room air The provider asks the nurse for input on whether the client may require hospital admission. Using the CURB-65 tool, which of the following is the most appropriate nursing recommendation?

Assuming random mating after migration and no selection or mutation, what would be the expected frequency of luminous frogs in the next generation?

Part C. What would be the expected frequency of individuals affected by the disease if first cousins mate? Hint: You need the answer from Part A to calculate this.  

Tarsanemia is a (made up) rare, autosomal recessive human disease caused by a mutation in the tar1 gene. In the general population, about 1 in 40,000 individuals is affected by Tarsanemia. What would be the expected frequency of individuals affected by the disease if siblings mate?

Use this statement to answer the following 3 questions (Parts A, B and C) Suppose that in a population the frequency of a particular autosomal recessive condition caused by allele a, is 1/800. Assume the population is at Hardy–Weinberg equilibrium.

L4: Tall plant height  (T) is dominant over short (t). You cross a tall and a short plant and obtain the following tall and short progeny. What is the most probable genotype of the parents?  

L3: Which of the following is correctly referred to as an F2 individual?

L6: Labradors can be black, brown or yellow, and their coat color depends on two loci.  One determines coat color, with black (B) dominant over brown (b). Another locus determines deposition of color in the fur, with color deposition (E) is dominant over no color deposition (e).  You cross a black Labrador homozygous for both traits with a yellow Labrador.  What are the genotypes and phenotypes of the expected progeny?
