A client has arrived at the clinic for a routine physical examination. Prior to assessing the client's blood pressure, what should the nurse do?

Choice A Reason:
Rhinitis medicamentosa, also known as rebound congestion, is a condition of nasal congestion without other cold or allergy symptoms, typically caused by the overuse of nasal decongestant sprays. It does not usually present with chronic headaches or tenderness over the sinuses, which are more indicative of sinusitis.

Choice B Reason:
Acute bacterial sinusitis is likely the correct diagnosis in this scenario. It often follows a viral upper respiratory infection and presents with symptoms such as thick, discolored nasal mucus, decreased sense of smell, and facial pain or tenderness over the affected sinuses. The chronic headache and noted tenderness upon palpation over the sinuses in the client are consistent with this condition.

Choice C Reason:
Epistaxis, or nosebleed, is bleeding from the nose that can be caused by various factors, including trauma, medication, or environmental conditions. While it can be a symptom of other nasal conditions, it is not typically associated with chronic headaches or sinus tenderness following an upper respiratory infection.

Choice D Reason:
Allergic rhinitis is an allergic reaction to allergens such as pollen, dust, or pet dander, causing symptoms like sneezing, runny nose, itchy eyes, and sometimes headaches. However, the chronic headache and sinus tenderness described by the client after an infection are more suggestive of sinusitis rather than allergic rhinitis.

Choice a reason:
The oral mucosa is the most reliable area to evaluate for central cyanosis in a client with asthma. Central cyanosis reflects a decrease in arterial oxygenation and is best assessed where the blood flow is high and the skin is thin, which is the case with the oral mucosa. It is less likely to be affected by peripheral factors such as temperature and is therefore a more accurate indicator of oxygen saturation in the central circulation.

Choice b reason:
While ear lobes can show signs of cyanosis, they are not the most reliable indicator of central cyanosis because they are more prone to peripheral cyanosis. Peripheral cyanosis can occur in the ear lobes due to local vasoconstriction or decreased blood flow, which may not reflect central oxygenation levels.

Choice c reason:
The soles of the feet are not a reliable indicator of central cyanosis, especially in a client with asthma. The skin on the soles is thicker and has less blood flow compared to the oral mucosa, making it a poor site for assessing central cyanosis. Additionally, the soles can be affected by peripheral factors like pressure and temperature.

Choice d reason:
Conjunctivae are not the most reliable indicator of central cyanosis. While they can show signs of cyanosis, the assessment can be affected by environmental factors and the presence of blood vessels in the conjunctiva that may not accurately reflect central oxygenation levels.
