Topic: Common Respiratory Complaints
A 75-year-old man with a history of hypertension, diabetes, environmental allergies, and colon polyps presents to the office with a complaint of persistent dry hacking cough that does not improve with over-the-counter treatment with antitussives and allergy medications. The man reports that he has had the cough for three months and is tired of the coughing spells he experiences. His medical history reveals that he started taking lisinopril six months before this appointment, has taken an over-the-counter allergy medication for several years, had his last colon polyps removed six years ago, and his blood pressure today is 145/70. Other medications include metformin XR 500 mg daily, aspirin 81 mg once daily, and loratadine 10 mg daily. The physical exam is negative for any issues other than his mild neuropathy from long-term diabetes. The cough is noted to be dry and hacking as the patient has described. The man is not in acute distress.

Introduction:
Respiratory complaints are common among patients presenting to medical offices, and these complaints can be caused by various factors. This case involves a 75-year-old man with a persistent dry hacking cough that did not improve with over-the-counter medications. The patient has a history of hypertension, diabetes, environmental allergies, and colon polyps. In this assignment, we will answer questions related to the patient’s medical history, physical examination, diagnosis, and treatment plan.
1. Using OLDCARTS, what questions would have been asked as part of the medical history?
In evaluating respiratory complaints, the OLDCARTS acronym can be used to obtain a detailed medical history. The following questions would be asked:
– Onset: When did the cough start, and how often does it occur?
– Location: Is the cough localized to a particular area of the chest, or does it affect the entire chest?
– Duration: How long has the cough been present?
– Characteristics: What is the nature of the cough – dry or productive? Is there sputum production, and if so, what is the color and amount?
– Aggravating/relieving factors: Are there any activities or situations that worsen or improve the cough?
– Related symptoms: Are there any other respiratory or non-respiratory symptoms associated with the cough, such as dyspnea, wheezing, fever, or weight loss?
– Treatment: Has the patient tried any over-the-counter medications or home remedies to relieve the cough, and if so, what was the response?
– Severity: How severe is the cough, and how does it affect the patient’s daily activities?
2. What physical aspects would have been completed as part of the physical exam and why? Include the diagnostics that you would order and rationale.
In conducting the physical exam, the following aspects would be evaluated:
– Vital signs: blood pressure, heart rate, respiratory rate, and temperature
– Inspection of the chest and respiratory effort
– Auscultation of breath sounds, including any wheezes, crackles, or rhonchi
– Examination of the ear, nose, and throat to rule out postnasal drip or other upper respiratory infections
– Palpation of the neck and thyroid gland
– Assessment of the heart and lungs
Based on the patient’s medical history and physical exam findings, the following diagnostics would be considered:
– Chest X-ray to rule out pulmonary infections or masses
– Spirometry and peak flow measurement to assess lung function and rule out underlying asthma or chronic obstructive pulmonary disease (COPD)
– Blood tests to evaluate for infection, anemia, or metabolic disorders
3. Based on the medical history and physical exam, what is the most likely cause of his cough?
The most likely cause of the patient’s cough is an adverse reaction to his medication, specifically lisinopril, which is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension. ACE inhibitors are known to cause coughs in up to 20% of patients, and the cough is typically described as dry and persistent.
4. What other possible diagnoses should be considered and why?
Other possible diagnoses that should be considered include:
– Chronic obstructive pulmonary disease (COPD) or emphysema, as the patient has a history of smoking and diabetes, which are risk factors for these conditions.
– Asthma, as the patient has a history of environmental allergies and a family history of asthma.
– Gastroesophageal reflux disease (GERD), as chronic cough can be a symptom of GERD and the patient takes aspirin, which can aggravate GERD.
– Postnasal drip, as the patient has a history of environmental allergies and may be experiencing irritation due to mucus dripping down the back of the throat.
5. Are there any other tests that should be completed before producing a diagnosis? Why or why not?
Before producing a diagnosis, a trial of medication withdrawal should be considered. Lisinopril should be discontinued or changed to an alternative medication to determine if the cough resolves. If the cough persists despite medication changes, further diagnostic tests may be required, such as a CT scan of the chest or bronchoscopy to evaluate for lung masses or tumors.
6. What is the treatment for this patient, including education?
The treatment for this patient would involve discontinuation of lisinopril and assessment of the patient’s blood pressure to determine if alternative antihypertensive medication is required. Essential education for the patient includes educating the patient on the potential side effects of ACE inhibitors, monitoring the blood pressure at home as recommended, avoiding allergens that may trigger coughing spells, and scheduling follow-up appointments to monitor the resolution of the cough and assess the effectiveness of the alternative medication.
