The primary factor responsible for possible multiple clinical manifestations in cystic fibrosis is which of the following?
Hyperactivity of sweat glands
Mechanical obstruction caused by increased viscosity of mucous gland secretion
Hypoactivity of autonomic nervous system
Atrophic changes in mucosal wall of intestines
The Correct Answer is B
A. Hyperactivity of sweat glands:
In cystic fibrosis (CF), there is an abnormality in the CF transmembrane conductance regulator (CFTR) protein, leading to increased salt concentration in sweat. However, this is not the primary factor responsible for the diverse clinical manifestations in CF. The primary issue lies in the abnormal production of thick and sticky mucus affecting various organs.
B. Mechanical obstruction caused by increased viscosity of mucous gland secretion:
This is the correct choice. CF is characterized by the production of thick and sticky mucus due to abnormal CFTR protein function. This increased viscosity leads to mechanical obstruction in organs such as the respiratory, digestive, and reproductive systems, causing a range of clinical manifestations.
C. Hypoactivity of the autonomic nervous system:
CF is not characterized by hypoactivity of the autonomic nervous system. The primary issue lies in the mechanical obstruction caused by the abnormal mucus production.
D. Atrophic changes in the mucosal wall of the intestines:
Atrophic changes in the mucosal wall of the intestines are not the primary factor responsible for the clinical manifestations of CF. The key problem is the mechanical obstruction due to increased viscosity of mucous gland secretions.

Correct Answer is A
Explanation
A. Peak expiratory flow meter:
- A peak expiratory flow meter is a device used to measure how fast a person can exhale. It is commonly used to monitor and manage asthma by assessing the degree of airway obstruction. Regular use can help determine how well asthma is controlled and whether changes in the management plan are needed.
B. Inhaled steroids:
- Inhaled steroids are a type of long-term control medication used to manage asthma by reducing inflammation in the airways. While these are essential for controlling symptoms, they do not directly assess how well the asthma is currently controlled.
C. Metered dose inhaler with spacer:
- A metered dose inhaler (MDI) with a spacer is a device used to deliver medication directly to the lungs. While it is a crucial part of asthma management, it does not directly measure how well the asthma is controlled.
D. Pulse oximetry:
- Pulse oximetry measures the oxygen saturation in the blood and is useful in assessing respiratory status. However, it is not specific to asthma control and may not provide a comprehensive picture of asthma management.
Correct Answer is C
Explanation
A. Informed consent
Informed consent refers to the process of obtaining permission from a person who has the legal capacity to make decisions for themselves. It involves providing comprehensive information about the nature, risks, benefits, and alternatives of a medical intervention to enable the individual to make an informed decision.
B. Emancipation
Emancipation is a legal process that grants minors the status of being free from the control of their parents or guardians. It is usually granted based on factors such as maturity, financial independence, or special circumstances. Emancipated minors may have legal capacities similar to those of adults.
C. Assent
Assent is the process of obtaining a child's agreement or approval for medical treatment. It recognizes the child's developing capacity to understand the nature of the treatment, and it allows the child to express their willingness to participate in the decision-making process regarding their healthcare. Assent is sought in addition to the informed consent of the parents or legal guardians.
D. Confidentiality
Confidentiality involves keeping private information secure and not disclosing it without proper authorization. While confidentiality is an important aspect of healthcare, it is not specifically related to the process of obtaining a child's agreement to medical treatment.
