In reference to the flow diagram below respond to the following question. The annotation A refers to which sites
- A. Annealing
- B. Melting
- C. Restriction
- D. RNAse
Correct Answer: C
Rationale: The correct answer is C: Restriction. In a flow diagram, the annotation "Restriction" likely indicates the site where a DNA molecule is being cut by a restriction enzyme. This process is essential in molecular biology for DNA manipulation.
Choice A: Annealing involves the process of complementary DNA strands coming together, usually during PCR or hybridization.
Choice B: Melting refers to the separation of double-stranded DNA into single strands, often seen in denaturation steps.
Choice D: RNAse is an enzyme that specifically degrades RNA molecules, not involved in the DNA manipulation processes indicated in the diagram.
Which of the following characteristics do not occur in prokaryotic cells?
- A. cellular organization
- B. thylakoid membranes within chloroplasts
- C. oxygenic photosynthesis
- D. anaerobic respiration
Correct Answer: B
Rationale: The correct answer is B: thylakoid membranes within chloroplasts. Prokaryotic cells lack membrane-bound organelles like chloroplasts, where thylakoid membranes are found. This is a key feature of prokaryotic cells. Choices A, C, and D are characteristics that can occur in prokaryotic cells. Cellular organization is present in prokaryotic cells, oxygenic photosynthesis can be carried out by some prokaryotic organisms, and prokaryotic cells can perform anaerobic respiration.
What is the central component of the complement system?
- A. C1
- B. C2
- C. C3
- D. C5
Correct Answer: C
Rationale: The correct answer is C: C3. C3 is the central component of the complement system as it plays a crucial role in both the classical and alternative pathways by forming the C3 convertase enzyme. This enzyme initiates the cascade of reactions leading to opsonization, chemotaxis, and cell lysis. Choices A, B, and D are incorrect as C1 is the initiator of the classical pathway, C2 is involved in the formation of the C3 convertase, and C5 is necessary for the formation of the membrane attack complex.
What are the recommended measures to prevent the transmission of health care–associated infections (HAIs) (select all that apply)?
- A. Empty bedpans as soon as possible
- B. Use personal protective equipment
- C. Hand washing or alcohol-based sanitizing
- D. Have patients wear sandals in the shower
Correct Answer: B
Rationale: The correct answer includes options B and C. Using personal protective equipment and practicing proper hand hygiene are critical measures to prevent HAIs. Emptying bedpans promptly and having patients wear sandals in the shower are not directly related to preventing HAIs.
Priority Decision: Key interventions for treating soft tissue injury and resulting inflammation are remembered using the acronym RICE. What are the most important actions for the emergency department nurse to do for the patient with an ankle injury?
- A. Reduce swelling, shine light on wound, control mobility, and elicit the history of the injury
- B. Rub the wound clean, immobilize the area, cover the area protectively, and exercise that leg
- C. Rest with immobility, apply a cold compress, apply a compress bandage, and elevate the ankle
- D. Rinse the wounded ankle, image the ankle, carry the patient, and extend the ankle with imaging
Correct Answer: C
Rationale: RICE stands for Rest, Ice, Compression, and Elevation, which are critical steps in managing acute soft tissue injuries like sprains. These actions help reduce swelling, limit further damage, and promote healing.
