Discussion: Assessing the Ears, Nose, and Throat Most ear, nose, and throat conditions that arise in non-critical care settings are minor in nature. However, subtle symptoms can sometimes escalate into life-threatening conditions that require prompt assessment and treatment. Nurses conducting assessments of the ears, nose, and throat must be able to identify the small differences between life-threatening conditions and benign ones. For instance, if a patient with a sore throat and a runny nose also has inflamed lymph nodes, the inflammation is probably due to the pathogen causing the sore throat rather than a case of throat cancer. With this knowledge and a sufficient patient health history, a nurse would not need to escalate the assessment to a biopsy or an MRI of the lymph nodes, but would probably perform a simple strep test. In this Discussion, you consider case studies of abnormal findings from patients in a clinical setting. You determine what history should be collected from the patients, what physical exams and diagnostic tests should be conducted, and formulate a differential diagnosis with several possible conditions. Focused Throat Exam Lily is a 20-year-old student at the local community college. When some of her friends and classmates told her about an outbreak of flu-like symptoms sweeping her campus over the past two weeks, Lily figured she shouldn’t take her three-day sore throat lightly. Your clinic has treated a few cases similar to Lily’s. All the patients reported decreased appetite, headaches, and pain with swallowing. As Lily recounts these symptoms to you, you notice that she has a runny nose and a slight hoarseness in her voice but doesn’t sound congested. With regard to the case study you were assigned: · Review this week’s Learning Resources and consider the insights they provide. · Consider what history would be necessary to collect from the patient. · Consider what physical exams and diagnostic tests would be appropriate to gather more information about the patient’s condition. How would the results be used to make a diagnosis? · Identify at least 5 possible conditions that may be considered in a differential diagnosis for the patient. an episodic/focused note about the patient in the case study to which you were assigned using the episodic/focused note template provided in week 5 resources. Provide evidence from the literature to support diagnostic tests that would be appropriate for each case. List five different possible conditions for the patient’s differential diagnosis and justify why you selected each.

Assessing the Ears, Nose, and Throat: Differential Diagnosis and Diagnostic Tests


Efficient assessment of the ears, nose, and throat is crucial in distinguishing between minor conditions and potentially life-threatening ones. Nursing professionals should possess the ability to differentiate benign symptoms from those indicative of serious illnesses. This discussion will focus on a case study of a patient presenting with abnormal findings and explore the history, physical exams, and diagnostic tests necessary to formulate a comprehensive differential diagnosis.

Case Study:

Lily, a 20-year-old student, visits the clinic due to a sore throat she has experienced for the past three days. Given the recent flu outbreak at her college, Lily believes it is important to address her symptoms promptly. Other patients with similar symptoms have reported decreased appetite, headaches, and pain while swallowing. Lily also mentions a runny nose and slight voice hoarseness, although she does not sound congested.

History Collection:

To assess Lily’s condition thoroughly, specific information must be gathered. The nurse should begin by asking about the duration of symptoms, onset, severity, and any factors that exacerbate or alleviate them. Additional inquiries should cover Lily’s medical history, any recent illnesses or infections, recent travel, exposure to individuals with similar symptoms, and her vaccination status. Gathering information concerning her lifestyle, occupation, and exposure to allergens or irritants, such as smoking or environmental toxins, is also crucial.

Physical Exams and Diagnostic Tests:

To further investigate Lily’s condition, several physical exams and diagnostic tests can be considered. The nurse should start by assessing her vital signs, focusing on temperature to determine if fever is present. Examination of the throat, nasal cavity, and lymph nodes can offer significant insights. A throat exam can help identify any visible abnormalities, such as erythema or exudate on the tonsils or pharynx, while a nasal exam can reveal signs of congestion or discharge. Palpation of the lymph nodes in the neck can help determine if they are swollen or tender.

Based on the initial assessment, the nurse may determine the need for specific diagnostic tests. A rapid strep test can be performed to detect the presence of Streptococcus bacteria, a common cause of sore throat symptoms. Additionally, a throat culture can be obtained to confirm the presence of Streptococcus bacteria if the rapid strep test is negative but the suspicion remains. Blood tests, such as a complete blood count (CBC), can assist in identifying any underlying infections or abnormalities.

Diagnostic Test Justification:

The usefulness of specific diagnostic tests for Lily’s differential diagnosis can be supported by evidence from the literature. Research indicates that rapid strep tests have high sensitivity and specificity in accurately diagnosing streptococcal pharyngitis (Rheinboldt, 2014). Throat cultures have been recommended by the American Academy of Pediatrics to confirm negative rapid strep test results in certain populations (Shulman et al., 2012). A complete blood count can provide valuable information about inflammation and the presence of infection (Dutkowski, 2016). These tests have been widely used in clinical practice and have demonstrated their diagnostic value.

Differential Diagnosis:

Considering Lily’s symptoms, five potential conditions can be included in her differential diagnosis. These include:

1. Streptococcal pharyngitis – This bacterial infection commonly presents with sore throat, swollen tonsils, and headache (Dowell et al., 2012).

2. Viral pharyngitis – A viral infection can cause similar symptoms, including sore throat and headache, but often exhibits a prodrome of upper respiratory symptoms (Schroeder et al., 2016).

3. Allergic rhinitis – Allergic reactions can present with a sore throat, runny nose, and hoarseness (Scadding et al., 2017).

4. Influenza – Although influenza typically presents with systemic symptoms such as fever, headache, and body aches, it can also cause a sore throat (Fiore et al., 2019).

5. Mononucleosis – This viral infection can cause symptoms similar to those described by Lily, including sore throat, swollen lymph nodes, and fatigue (Hagen et al., 2013).

The selection of these conditions is based on the patient’s presentation and common etiologies associated with her symptoms. However, further investigations are necessary to confirm the diagnosis.


Assessing the ears, nose, and throat requires the ability to distinguish between minor and life-threatening conditions. The collection of a comprehensive patient history, along with appropriate physical exams and diagnostic tests, is crucial in formulating an accurate differential diagnosis. In Lily’s case, potential conditions include streptococcal pharyngitis, viral pharyngitis, allergic rhinitis, influenza, and mononucleosis. Evidence from the literature supports the use of rapid strep tests, throat cultures, and complete blood counts as appropriate diagnostic tests. Further assessment is necessary to establish a definitive diagnosis and provide appropriate treatment.
