It started a few hours ago, and she has noted nausea with sensitivity to light; she has had headaches like this in the past, usually less than one per week, but not as severe. She does not know of any inciting factors. There has been no change in the frequency of her headaches. She usually takes an over- the-counter analgesic, and this results in resolution of the headache. Based on this description, what is the most likely diagnosis of the type of headache?

Correct Answer: B

Rationale: The description of the headache as starting a few hours ago, associated with nausea, sensitivity to light, and being severe in intensity suggests a migraine headache. Migraine headaches are often accompanied by these symptoms, known as migraine features. The fact that the patient experiences headaches like this less than once a week and typically uses over-the-counter analgesics to relieve them is also suggestive of migraines. Tension headaches typically present as a more mild to moderate, band-like pressure around the head, without the associated symptoms of nausea and sensitivity to light. Cluster headaches are characterized by excruciating pain around one eye, often accompanied by other symptoms like redness or tearing in the eye. Analgesic rebound headaches occur due to overuse of pain medications and typically present as daily headaches that improve with the same medication that caused them in the first place.

Correct Answer: B

Rationale: The patient's presentation with an enlarged chest diameter, decreased breath sounds throughout all lobes, and the presence of rhonchi over all lung fields is suggestive of a chronic condition that affects the entire respiratory system. These findings are classic for COPD, a progressive lung disease characterized by airflow limitation. The breath sounds are decreased due to airflow obstruction, and the presence of rhonchi indicates mucus production and airway inflammation commonly seen in COPD. In contrast, a spontaneous pneumothorax would typically present with sudden chest pain and shortness of breath, often in a younger patient with risk factors such as smoking. Asthma would present with wheezing, shortness of breath, and possibly a history of atopy or allergies. Pneumonia would typically present with fever, cough, and focal findings on chest examination, such as crackles or bronchial breath sounds over a consolidated area. In

Correct Answer: C

Rationale: Leaving the plexor finger on the pleximeter after each strike is consistent with good percussion technique. This helps to maintain stability and precision during percussion by providing a consistent point of contact for accurate assessment of the underlying structures. This technique also helps to control the force and angle of the percussive strike, ensuring accurate interpretation of the resulting sounds produced. Maintaining this contact can enhance the effectiveness of percussion as a diagnostic tool in physical examinations.

Correct Answer: B

Rationale: Orthopnea is a symptom characterized by difficulty breathing while lying flat that improves when sitting or standing upright. This symptom is specifically related to cardiovascular conditions, such as heart failure, in which fluid accumulates in the lungs when lying down. Considering the patient's complaint of breathlessness with activity and the need to assess for cardiovascular issues, asking about orthopnea would be most appropriate to gain insights into potential heart-related causes of the symptoms. Abdominal pain (A), hematochezia (C), and tenesmus (D) are not typically associated with cardiovascular conditions and are less relevant to the patient's presentation.
