A nurse is assessing a client who has asthma and signs of central cyanosis. Which of the following is a reliable indicator of cyanosis?
A. Oral mucosa
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
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
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. Eye lids
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.

Order: Diphenhydramine 25mg Q4H
Available: Diphenhydramine 12.5mg/5mL
How much will you administer?
A. 2 mL
B. 10 mL
First, we need to find out how many milligrams (mg) are in 1 milliliter (mL) of the available diphenhydramine solution: 12.5 mg/5 mL To find out how many milligrams are in 1 mL, we divide the total milligrams by the total milliliters: 12.5 mg ÷ 5 mL = 2.5 mg/mL Now that we know the concentration of diphenhydramine is 2.5 mg/mL, we can calculate the dose needed for the order of 25 mg: 25 mg ÷ 2.5 mg/mL = 10 mL
C. 25mL

A patient is admitted to the hospital with SOB. The nurse notices increasing confusion and combativeness during the past hour. Which of the following actions is appropriate first?
A. Assess the patient; check to see if the oxygen is flowing correctly
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
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
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
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.

A patient has a diagnosis of Impaired Gas Exchange. Which assessment finding shows that the interventions have been effective?
A. The patient's Spo2 is 97% on 2L NC
The patient's Spo2 is 97% on 2L NC:This assessment finding indicates that the patient's oxygen saturation level (SpO2) is 97% while receiving 2 liters per minute of oxygen via nasal cannula. Oxygen saturation is a measure of the percentage of hemoglobin saturated with oxygen in the blood. A SpO2 level of 97% suggests adequate oxygenation, which is essential for effective gas exchange. Therefore, if the patient's SpO2 is within the target range on the prescribed oxygen therapy, it indicates that the interventions aimed at improving gas exchange have been effective.
B. The patient appears comfortable
The patient appears comfortable:While patient comfort is important, it is not a direct indicator of effective gas exchange. A patient may appear comfortable for various reasons, such as pain relief, proper positioning, or emotional support, but this does not necessarily reflect improved gas exchange. Therefore, while comfort is an important aspect of nursing care, it is not specifically indicative of the effectiveness of interventions for impaired gas exchange.
C. The patient is coughing up copious white sputum
The patient is coughing up copious white sputum: The presence of copious white sputum does not directly indicate improved gas exchange. White sputum may suggest various conditions, such as respiratory tract infections or inflammation, but it does not provide direct information about gas exchange efficiency. Effective gas exchange involves the exchange of oxygen and carbon dioxide at the alveolar-capillary membrane, which cannot be assessed solely based on sputum production.
D. The patient is able to move out of bed without difficulty
The patient is able to move out of bed without difficulty:The ability to move out of bed without difficulty may indicate improved overall physical function or mobility, but it does not specifically reflect improved gas exchange. Gas exchange primarily involves the transfer of oxygen from the alveoli into the bloodstream and the removal of carbon dioxide from the bloodstream into the alveoli for exhalation. While improved gas exchange may lead to enhanced physical endurance and reduced dyspnea, the ability to move out of bed without difficulty is not a direct measure of gas exchange efficiency.
