A nurse is assessing a client who has asthma and signs of central cyanosis. Which of the following is a reliable indicator of cyanosis?
Oral mucosa
Tip of the nose
Ear lobes
Eye lids
The Correct Answer is A
A. Oral mucosa:
The oral mucosa, including the inside of the mouth, tongue, and lips, is a reliable indicator of cyanosis. Cyanosis appears as a bluish discoloration of these tissues due to decreased oxygen saturation in the arterial blood. Assessing the oral mucosa is an essential component of clinical examination, especially in patients with respiratory conditions like asthma, as it provides valuable information about oxygenation status.
B. Tip of the nose:
While the tip of the nose may exhibit cyanosis in some cases, it is not considered as reliable of an indicator as the oral mucosa. The nasal tip is more susceptible to external factors such as cold temperatures or poor circulation, which can cause temporary discoloration. Therefore, it may not always accurately reflect the oxygenation status of the patient compared to the oral mucosa.
C. Ear lobes:
Cyanosis may be observed in the ear lobes in cases of severe hypoxemia, but it is not as reliable of an indicator as the oral mucosa. The ear lobes are less commonly assessed for cyanosis compared to other areas such as the lips, nail beds, or oral mucosa. While cyanosis may be present in the ear lobes, it is not typically the primary site assessed for oxygenation status.
D. Eyelids:
Cyanosis is not typically observed in the eyelids and is not considered a reliable indicator of hypoxemia. The eyelids are not commonly assessed for cyanosis during clinical examinations. While the conjunctiva (the lining inside the eyelids) may appear pale in cases of severe anemia, it is not a specific sign of hypoxemia. Assessment of the oral mucosa, lips, and nail beds is preferred for evaluating oxygenation status in patients with respiratory conditions like asthma.

Correct Answer is A
Explanation
A. Expiratory wheeze
Expiratory wheeze is a high-pitched, musical sound heard primarily during expiration. It occurs when air passes through narrowed airways due to bronchoconstriction, inflammation, and increased mucus production, which are characteristic features of an acute asthma exacerbation. Expiratory wheezes are commonly heard upon auscultation of the chest in individuals experiencing asthma exacerbations.
B. Pleural friction rub
Pleural friction rub is a dry, crackling or grating sound heard during both inspiration and expiration. It typically occurs when the inflamed pleural surfaces rub against each other during breathing. Pleural friction rub is associated with conditions such as pleurisy (inflammation of the pleura) or pleural effusion (accumulation of fluid in the pleural space), rather than asthma exacerbations.
C. Fine rales
Fine rales, also known as fine crackles, are brief, high-pitched, discontinuous sounds heard primarily during inspiration. They are typically associated with conditions involving the small airways and alveoli, such as pulmonary fibrosis or congestive heart failure. Fine rales are not commonly heard in asthma exacerbations.
D. Rhonchi
Rhonchi are low-pitched, snoring or rattling sounds heard primarily during expiration. They result from the passage of air through airways obstructed by thick mucus or secretions. While rhonchi may be heard in individuals experiencing asthma exacerbations, they are less characteristic than expiratory wheezes, which are more commonly associated with asthma exacerbations. Rhonchi are often associated with conditions such as chronic bronchitis or pneumonia.
Correct Answer is A
Explanation
A. Assess the patient; check to see if the oxygen is flowing correctly:
This option involves assessing the patient's condition promptly, particularly focusing on the adequacy of oxygenation. Checking the oxygen delivery system ensures that the patient is receiving the prescribed oxygen therapy at the appropriate flow rate. In a patient with shortness of breath (SOB) and increasing confusion and combativeness, hypoxemia (low oxygen levels) could be a contributing factor. Therefore, assessing the oxygen delivery system is crucial to ensure proper oxygenation and address potential causes of the patient's symptoms.
B. Page the MD STAT:
Paging the MD STAT may be necessary after assessing the patient's condition, especially if the patient's symptoms indicate a medical emergency or require immediate intervention. However, in this scenario, the priority is to assess the patient's condition and address any immediate concerns related to oxygenation and respiratory status. While paging the healthcare provider may be necessary, it should not delay the initial assessment and interventions needed to stabilize the patient.
C. Put up the patient's side rails and apply soft restraints:
Applying side rails and soft restraints should not be the first action in response to the patient's symptoms. While patient safety is important, these measures should only be implemented after other interventions have been attempted, and there is a risk of harm to the patient or others due to agitation or combativeness. In this case, the patient's confusion and combativeness may be secondary to hypoxemia, so addressing oxygenation and assessing the patient's condition are the immediate priorities.
D. Administer an IM sedative:
Administering a sedative should not be the first action in this scenario. Sedation may be considered if the patient's agitation or combativeness poses a risk to their safety or interferes with assessment and treatment. However, the underlying cause of the patient's symptoms, such as hypoxemia, should be addressed first. Administering a sedative without addressing the potential cause of the patient's symptoms could mask important clinical indicators and delay appropriate treatment.
