A nurse is reviewing arterial blood gas results for a client diagnosed with chronic obstructive pulmonary disease (COPD). The nurse should expect which abnormal finding?
Increased arterial oxygen
Increased pH
Increased carbon dioxide
Decreased alveolar function
The Correct Answer is C
A. Increased arterial oxygen: Clients with COPD typically experience chronic hypoxemia due to alveolar destruction, airway inflammation, and mucus production, which impair gas exchange. Rather than increased oxygen levels, they often have a decreased PaO₂, requiring supplemental oxygen therapy. However, excessive oxygen administration can suppress their respiratory drive, worsening CO₂ retention.
B. Increased pH: COPD is associated with respiratory acidosis due to chronic CO₂ retention from inadequate alveolar ventilation. While the kidneys compensate by increasing bicarbonate retention, the pH usually remains low or near normal in chronic cases rather than becoming elevated. A higher pH would indicate alkalosis, which is not typical in COPD unless there is an additional metabolic disturbance.
C. Increased carbon dioxide: COPD causes airway obstruction and reduced alveolar ventilation, leading to CO₂ retention (hypercapnia). As CO₂ accumulates in the blood, it lowers the pH, resulting in respiratory acidosis. Chronic hypercapnia is a hallmark of advanced COPD, and in response, the kidneys retain bicarbonate to partially compensate, stabilizing the pH over time but leaving PaCO₂ elevated.
D. Decreased alveolar function: While COPD does lead to progressive alveolar damage and reduced gas exchange, this is a structural and functional change rather than a specific abnormality seen in arterial blood gases. The primary ABG finding in COPD is hypercapnia, which reflects inadequate ventilation and CO₂ retention rather than just decreased alveolar function alone.

Correct Answer is ["4"]
Explanation
Formula:
Volume to administer (mL) = (Desired dose (mg) / Available concentration (mg/mL))
Desired dose = 1.6 mg
Available concentration = 2 mg / 5 mL
Calculate the concentration per mL:
2 mg / 5 mL = 0.4 mg/mL
Volume to administer = 1.6 mg / 0.4 mg/mL
= 4 mL
The nurse should administer 4 mL per dose.
Correct Answer is ["A","C","E"]
Explanation
A. Culturally incompetent caregivers. When healthcare providers lack cultural awareness, they may struggle to communicate effectively with patients from diverse backgrounds. This can lead to misunderstandings, decreased trust, and reduced adherence to treatment plans. Patients may feel unheard or disrespected if their cultural beliefs and preferences are not considered. Cultural competence training helps bridge communication gaps and improves patient-provider relationships.
B. Proper training in healthcare communication. Training in communication enhances a provider’s ability to listen actively, use clear language, and foster patient-centered interactions. It helps reduce medical errors, improve patient understanding, and enhance trust in healthcare providers. Since communication training strengthens interactions rather than hindering them, it is not considered a barrier. Well-trained providers can adapt their approach to meet the needs of each patient effectively.
C. Implicit bias. Unconscious biases can negatively affect how healthcare providers interact with patients, leading to disparities in care. Providers may unintentionally assume things about a patient based on stereotypes rather than their individual needs. This can cause miscommunication, lack of trust, and reluctance to seek care. Recognizing and addressing implicit bias is crucial for ensuring equitable and effective communication.
D. Excellent health literacy. High health literacy enables patients to understand medical information, follow treatment plans, and communicate effectively with providers. This reduces confusion, enhances decision-making, and improves health outcomes. Since excellent health literacy helps rather than hinders communication, it is not a barrier. Instead, it empowers patients to engage more actively in their care.
E. Lack of diversity. A lack of diversity in healthcare can result in communication barriers, as providers may be less familiar with different cultural perspectives and language needs. This can lead to misunderstandings, decreased patient satisfaction, and reduced quality of care. A diverse healthcare workforce fosters inclusivity, improves provider-patient communication, and promotes better health outcomes. Encouraging diversity ensures a more culturally competent and responsive healthcare system.
