In this chapter, you should have studied the steps of a skeletal muscle contraction (sliding filament mechanism).

1. Briefly outline the steps below:

Answers

Answer 1

The following steps are involved in sliding filament theory:

Release of calcium ions from sarcoplasmic reticulum - depolarization.Formation of cross bridge by myosin (head region) and actin filaments.Binding of ATP on myosin heads → Breakdown of cross bridge → ATP hydrolysisMuscle contraction through sarcomere shortening.

What is skeletal muscle?

Skeletal muscle consists of specialized tissues that have the property of contractibility. Skeletal muscles are composed of numerous muscle fibers tubular in appearance. Each muscle fiber contains rod like myofibrils.

Skeletal muscles are known as striated muscles because of the presence of alternating bands of light and dark (based on thickness) in their appearance under the microscope.

Thus, skeletal muscles are voluntary muscles.

110- The nurse is caring for the following group of clients. Which should the nurse assess first?
Select one:
• a. A 74-year-old who is pale, diaphoretic and has a hemoglobin of 9.9
• b. A 29-year-old female with painful intercourse, pelvic pain and a WBC count of 11.0
© c. A 86-year-old who has a cough, shortness of breath and a WBC of 18.3
• d.A 38-year-old with cough, shortness of breath and a WBC count of 17.0

Answers

Based on the information provided, the nurse should assess  option A. the 74-year-old who is pale, diaphoretic, and has a hemoglobin level of 9.9 first.

This client's symptoms suggest possible anemia, which can lead to insufficient oxygen supply to tissues and organs. Pale skin and diaphoresis are signs of decreased perfusion, indicating that the client's condition may be deteriorating.

The low hemoglobin level further supports the need for immediate assessment, as it indicates a decreased capacity of red blood cells to carry oxygen. While the other options also require attention, they are not as immediately life-threatening as the potential anemia in option a. The 29-year-old with painful intercourse, pelvic pain, and a WBC count of 11.0 (option b) may indicate an infection, but it is not an immediate emergency.

The 86-year-old with a cough, shortness of breath, and a WBC count of 18.3 (option c) may suggest a respiratory infection, but it does not indicate a life-threatening condition requiring immediate intervention. Similarly, the 38-year-old with a cough, shortness of breath, and a WBC count of 17.0 (option d) may also indicate a respiratory infection, but it does not pose an immediate threat to the client's life.

In summary, the nurse should prioritize assessing the 74-year-old who is pale, diaphoretic, and has a low hemoglobin level, as this may indicate anemia and a potential risk of decreased oxygen supply to tissues and organs. Therefore the correct option is a

Which of the following is an example of concealing symptoms of stress by reducing your body's sensitivity to the symptoms?
A. Breathing
B. Arousal reduction
C.Drug and alcohol use
D.Autogenic training

Answers

Drug and alcohol use is an example of concealing symptoms of stress by reducing the body's sensitivity to the symptoms. However, relying on substances for stress management is not a healthy or effective long-term solution. It is important to explore healthier coping strategies and seek support when dealing with stress. (optipn C)

An example of concealing symptoms of stress by reducing your body's sensitivity to the symptoms is drug and alcohol use. When individuals engage in substance abuse, such as using drugs or consuming alcohol, they may temporarily numb or mask the physical and psychological symptoms of stress.Substances like drugs and alcohol can alter the functioning of the central nervous system, affecting neurotransmitters and brain activity. This can lead to a decrease in sensitivity to stress-related symptoms, providing temporary relief or escape from the distressing effects of stress.While drug and alcohol use may provide temporary relief, it is important to note that it is not a healthy or sustainable coping mechanism. Relying on substances to cope with stress can have significant negative consequences on physical health, mental well-being, relationships, and overall quality of life.Instead of resorting to substance use, it is recommended to adopt healthier coping strategies for managing stress. These may include practicing relaxation techniques (such as breathing exercises or autogenic training), engaging in regular physical exercise, seeking social support, engaging in hobbies or activities that bring joy, and seeking professional help if needed.It is essential to address the underlying causes of stress and develop healthier coping mechanisms to promote long-term well-being and resilience in the face of stressors.
