The nurse advises that, to reduce the risk of giving a cold to another, one should: (Select 3 correct answers)
drink juices high in vitamin C
cough into your elbow
wash hands frequently
cover the mouth and nose with when sneezing
use a saline nose spray frequently
Correct Answer : B,C,D
A. Drink juices high in vitamin C: While vitamin C may help support immune function, it does not prevent the transmission of colds to others. This measure is more about personal health and has no direct effect on reducing contagion.
B. Cough into your elbow: Coughing into the elbow instead of the hands prevents the spread of respiratory droplets through touch, reducing the likelihood of contaminating surfaces and infecting others.
C. Wash hands frequently: Hand hygiene is one of the most effective ways to prevent the spread of respiratory viruses. Frequent handwashing helps remove viruses acquired from contaminated surfaces or respiratory secretions.
D. Cover the mouth and nose when sneezing: Covering the mouth and nose with a tissue or elbow during sneezing limits the dispersion of infectious droplets into the air, reducing transmission to others.
E. Use a saline nose spray frequently: Saline sprays may keep nasal passages moist and comfortable, but they do not reduce the risk of spreading infection to others. Their use is symptomatic, not preventive from a contagion standpoint.

Correct Answer is A
Explanation
A. Bacteria:Antibiotics are specifically used to treat bacterial infections. In the case of pharyngitis, antibiotics are appropriate if the infection is caused by Streptococcus pyogenes(Group A strep), which can be confirmed via rapid strep test or throat culture.
B. A fungal infection:Fungal infections are treated with antifungal medications, not antibiotics. Pharyngitis caused by fungi (e.g., Candida) is rare and requires different pharmacologic management.
C. A virus:Viral pharyngitis is the most common cause of sore throat and does not respond to antibiotics. Treating viral infections with antibiotics contributes to antimicrobial resistance and unnecessary side effects.
D. Protozoa:Protozoal infections typically affect the gastrointestinal or urogenital tract and are not a cause of pharyngitis. They are treated with antiparasitic agents, not antibiotics.
Correct Answer is C
Explanation
A. Administer IV antibiotics:Antibiotics are essential for treating the underlying infection, but their effect on improving oxygenation is not immediate. While they target the pneumonia-causing pathogen, they do not directly support respiratory function in the acute phase.
B. Encourage oral fluids:Hydration helps thin secretions and supports overall recovery, but oral fluids alone will not rapidly improve oxygen saturation in a patient with hypoxemia. This intervention is supportive but not the most urgent or direct for addressing oxygenation.
C. Apply nasal cannula oxygen @ 2L/min via nasal cannula:With an oxygen saturation of 89%, immediate oxygen supplementation is necessary to improve tissue oxygenation and prevent hypoxia-related complications. Administering oxygen by nasal cannula is the most appropriate and timely action to increase oxygen delivery.
D. Monitor blood glucose levels:Blood glucose monitoring is important, especially in a diabetic patient with infection, but it does not address the respiratory compromise. It is a priority for metabolic management, not for improving oxygenation directly.
