The mechanism of action of anticholinergic drugs used to treat asthma involves their ability to block the action of acetylcholine, a neurotransmitter in the parasympathetic nervous system.
In asthma, excessive cholinergic activity can lead to bronchoconstriction, mucus production, and airway hyperresponsiveness. Anticholinergic drugs, such as ipratropium bromide (Atrovent), work by binding to muscarinic receptors in the airways, specifically the M3 receptors, and competitively inhibit the binding of acetylcholine.
By blocking the cholinergic signaling, anticholinergic drugs help to relax the smooth muscles in the airways, leading to bronchodilation and improved airflow. This reduces the symptoms of asthma, such as wheezing and shortness of breath.
Anticholinergic agents primarily target the parasympathetic pathway, which is responsible for promoting bronchoconstriction. By counteracting the effects of acetylcholine, they help restore the balance in the autonomic nervous system and provide relief in asthma by dilating the airways.

An obese client must self-administer insulin at home. The nurse should teach the client to use what technique?
1 Pinch the tissue and inject at a 45-degree angle
2 Pinch the tissue and inject at a 60-degree angle
3 Spread the tissue and inject at a 45-degree angle
4 Spread the tissue and inject at a 90-degree angle
The correct technique for an obese client to self-administer insulin at home is to pinch the tissue and inject at a 90-degree angle (Option 4).
This ensures that the insulin is injected into the subcutaneous tissue and not into the muscle, which can affect the absorption rate and effectiveness of the insulin. The angle and technique may vary depending on the individual's body type and insulin regimen, so it is important for the nurse to assess and teach the client based on their specific needs.
When administering insulin injections, the technique of spreading the tissue and injecting it at a 90-degree angle is generally recommended for individuals with an adequate amount of subcutaneous tissue, including obese clients. This technique helps ensure that the insulin is delivered into the subcutaneous layer and not injected too superficially or into muscle.
Option 1, which suggests pinching the tissue and injecting at a 45-degree angle, is commonly used for individuals with less subcutaneous tissue to prevent injecting into the muscle layer. Option 2, pinching the tissue and injecting at a 60-degree angle, is not a commonly recommended technique for insulin injections.
Option 3, spreading the tissue and injecting it at a 45-degree angle, is also not commonly recommended for insulin injections. Hence, the 1 option is correct.

False. Growth stunting is not the greatest health-related concern of low calcium intake among adolescents.
While calcium is essential for proper growth and development, the greatest health-related concern of low calcium intake among adolescents is not specifically growth stunting. Calcium plays a vital role in bone health, muscle function, nerve transmission, and blood clotting. Insufficient calcium intake during adolescence can lead to a variety of health issues, including a higher risk of developing osteoporosis later in life, reduced bone mineral density, and an increased susceptibility to fractures.
During adolescence, the body undergoes significant bone growth and remodeling. Adequate calcium intake during this period is crucial for achieving peak bone mass, which directly affects long-term bone health. Insufficient calcium intake can compromise bone development and increase the risk of osteoporosis, a condition characterized by weak and brittle bones.
While growth stunting can be a consequence of severe malnutrition or other underlying factors, it is not the primary concern related to low calcium intake among adolescents. Maintaining a balanced and nutrient-rich diet, including sufficient calcium intake, is essential for overall health and optimal bone development during this critical stage of life.

The concentration of hydrocodone is 1.5 mg per tablet. We must divide the dose by the concentration to determine how many tablets to give the dog.1.496 mg ÷ 1.5 mg per tablet = 1 tablet. The dog needs one 1.5 mg tablet every 12 hours for ten days. Therefore, we need a total of 20 tablets to complete the course of treatment.
