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 D
Explanation
A. Blood pressure of 138/84 mmHg:This is within the acceptable range for a 68-year-old adult, especially with a history of hypertension. It does not indicate an acute threat or require immediate intervention in the context of pneumonia.
B. WBC count of 15,000/mm³:An elevated WBC count is expected in response to infection, such as pneumonia. While it confirms an inflammatory process, it is not the most urgent issue requiring immediate nursing action.
C. Blood glucose of 198 mg/dL:This mild hyperglycemia is not uncommon in infections and stress responses, particularly in patients with diabetes. It should be monitored, but it is not an immediate danger to the patient.
D. Oxygen saturation 89%:This low oxygen saturation indicates hypoxemia and impaired gas exchange, which is critical in a patient with pneumonia. Immediate oxygen therapy is necessary to prevent tissue hypoxia and respiratory failure.
Correct Answer is D
Explanation
A. A 16-year-old female high school student:While TB can affect people of any age, high school students are generally not considered a high-risk group unless they have known exposure or immunosuppression. Routine exposure in school settings is relatively low.
B. A 54-year-old businessman:This client may be at risk depending on travel history or comorbidities, but business professionals typically have better access to healthcare and housing, reducing their baseline risk compared to other populations.
C. A 54-year-old businessman:Unless other risk factors are specified (e.g., foreign travel, immunocompromise), this demographic does not represent a high-risk group for TB in an outbreak situation.
D. A 43-year-old homeless man with a history of alcoholism:This client falls into a high-risk category for TB due to poor living conditions, potential malnutrition, and compromised immunity related to alcoholism. Homelessness and substance use are well-established risk factors for tuberculosis, especially during outbreaks.
