When treating Baby John, who has been diagnosed with a lower respiratory infection, the selection of drugs of choice for the treatment depends primarily on:

Correct Answer: C

Rationale: The primary factor in selecting drugs for the treatment of a lower respiratory infection in Baby John is the sensitivity of the organism causing the infection. The choice of antibiotics should be guided by the susceptibility of the specific pathogen to ensure effective treatment and prevent resistance.

Correct Answer: B

Rationale: Asthma in children like Mabele can be triggered by exposure to allergens, leading to an allergic reaction in the bronchioles. This reaction causes constriction of the bronchial tree, resulting in an asthmatic attack. It is essential for caregivers to identify and minimize exposure to these triggers to manage and prevent asthma episodes effectively.

Correct Answer: C

Rationale: The classical clinical manifestations of diabetes mellitus include polyuria (increased urination), polydipsia (excessive thirst), and weight loss. Diabetic ketoacidosis is not a classical manifestation but rather a serious complication that can occur in individuals with uncontrolled diabetes.

Correct Answer: A

Rationale: Type 1 diabetes typically occurs after pubertal onset. This form of diabetes is most commonly diagnosed in individuals under the age of 30, with a peak incidence in the mid-teens to early 20s. Puberty is a period of hormonal changes and growth, which can trigger the onset of type 1 diabetes due to the stress it places on the body's insulin-producing cells.

Correct Answer: C

Rationale: Inability to lie supine is a significant indication of lower respiratory infection. This symptom often occurs due to breathing difficulties and discomfort experienced by individuals with lower respiratory infections, such as pneumonia or bronchitis. It can be caused by lung inflammation, consolidation, or fluid buildup in the lungs, making lying flat uncomfortable or difficult. Monitoring a patient's ability to lie flat can provide valuable information about the severity and progression of a lower respiratory infection.

Correct Answer: A

Rationale: Children with GH deficiency may face challenges due to their size, but it is important to encourage their participation in activities like playing ball games to promote healthy self-esteem. Allowing the child to play can help in building confidence and a sense of accomplishment, which are essential for their overall well-being.

Correct Answer: A

Rationale: Status asthmaticus is a life-threatening condition characterized by a severe and prolonged asthma attack that does not respond to standard treatments. It requires immediate medical intervention to prevent respiratory failure and potential fatality. Reactive airway disease, intrinsic asthma, and extrinsic asthma do not specifically denote the severity and unresponsiveness to treatment seen in status asthmaticus.

Correct Answer: D

Rationale: Systematically rotating injection sites is crucial to prevent tissue damage and ensure optimal insulin absorption. This practice helps in preventing lipohypertrophy, a condition characterized by fat accumulation at injection sites, which can affect insulin absorption and lead to inconsistent blood glucose control. By rotating injection sites, the risk of skin and tissue damage is minimized, and insulin's effectiveness is maintained over time.

Correct Answer: B

Rationale: In a toddler presenting with sudden hoarseness, holding or pointing to their neck, and continuous cough, the nurse should be particularly concerned about respiratory tract obstruction caused by a foreign body. These symptoms are indicative of a possible foreign body in the airway, which can lead to serious complications and requires immediate attention to ensure the toddler's airway remains patent and unobstructed.
