<span>Answer: A client who has symptoms of infection but whose culture and sensitivity results are not yet available
Broad-spectrum antibiotics are often used to treat infections of a client who has symptoms of infection but whose culture and sensitivity results are not yet available. The presence of a fever say a client with an oral temperature of 37.9</span>°C,<span> would not be an indication also to use broad-spectrum antibiotics. Age also. </span>

Explanation:
Prophase, Metaphase, Anaphase, Telophase
Each cell contains thousands of different proteins.
Answer:A. The release of calcium ions causes myosin and actin to attach to each other.
The contraction of skeletal muscles takes place by induction of a nerve impulse, which produces a movement and the interaction of the filaments containing proteins named as actin and myosin. This interaction of filaments is regulated by proteins called tropomyosin and troponin present on the actin filaments. The motor nerve causes the depolarization of the muscle membrane sarcolemma. This triggers the sarcoplasmic reticulum to release calcium ions. This calcium binds to troponin and thus allows the tropomyosine strand on the actin filament to displace so that the part of the actin where myosine head needs to be attached remain uncovered. Binding of the actin myosine filament results in contraction.
Hence, the release of calcium ions causes myosin and actin to attach to each other causes muscle contraction.
