Choose the phase of the bacterial growth curve during which a bacterial population has the briefest doubling time.

Clinical Scenario: Breonna Jones is 16 years old, 5’4”, and weighs 93 lb. She was admitted to an inpatient medical unit 2 days ago after collapsing at the local high school. Her parents knew she was skinny and had lost weight in the past few months, but had no idea that her life was in danger. The medical team has instituted treatment for anorexia nervosa. As you develop Breonna’s nursing plan of care, you take into consideration the four major biological molecules that are building blocks of all cells. The nurse implements an extensive nutrition education plan for Breonna, beginning at the molecular level. Carbohydrates, lipids, proteins, and nucleic acids are the four main families of biological molecules referred to as _____.

Each of the following are denaturing agents except_________.

Read the clinical scenario, and then answer the questions that follow.An 18-month-old male is admitted to the hospital with symptoms of a respiratory infection. The patient’s mother reports that since birth, the toddler has frequently had a cough and copious nasal secretions. His weight gain has been poor, despite his excellent appetite. The patient appears in moderate respiratory distress, so oxygen therapy and intravenous fluids are initiated. The physician orders tests for cystic fibrosis due to the patient’s history and clinical presentation. When the tests confirm the diagnosis, as the RN, you provide education to the mother regarding this autosomal recessive disease. You educate the patient’s mother that the most common cause of cystic fibrosis is a deletion of three nucleotides. Which of the following statements, by the mother, demonstrates an understanding of the disease etiology?

If the mRNA codon for alanine is GCA, then the correct anticodon would be _________.

Three consecutive bases in the DNA of a gene represent the code for one _________.

Please read the clinical scenario, and then answer the question that follow.The hospital infectious disease team is involved with the study of a healthcare-associated infection that has spread to 10% of inpatients. The infected patients are exhibiting symptoms of severe abdominal cramping, diarrhea, nausea, and vomiting. The RN on the infectious disease team provides education to staff regarding the pattern of bacterial growth and methods of infection control. The most rapid increase in bacterial growth occurs during which of the following stages?

Endospores of certain bacterial species can enter tissues in the human body, germinate, and cause an infectious disease.

Clinical Scenario: An RN is working at a public health clinic that sees many patients with infectious disease. Ms. Hungh, a Burmese immigrant, presents to the clinic with an interpreter, complaining of fatigue, weight loss, persistent cough, and rust-colored sputum. The interpreter explains that Ms. Hungh has had this cough for many months in her home country and, now that she is in America, is seeking treatment for her condition. Culturing of the sputum resulted in the growth of distinct colonies and further isolation by subculturing is now needed. The RN understands that isolation is accomplished by taking a bit of growth from an individual colony and inoculating a separate medium, resulting in the production of a/an_________.

The_________ is all of the genetic material of a cell.
