A 40-year-old man presents to a clinic with an onset of a
frequent cough. The patient states the cough started when he
started his new blood pressure medication two weeks ago. The
patient does not remember the name of the drug that was started.

being caused by an infection. It is determined the likely cause of
the frequent cough is the new blood pressure medication.
Which medication is the likely cause of this patient's symptoms?
Correct Answers Lisinopril (Zestril) -
ACE inhibitors such as lisinopril (Zestril) are associated with
dry, persistent coughing in many patients. They prevent the
breakdown of protussive mediators such as bradykinin and
substance P leading to an increase of these mediators in the
respiratory tract. The cough is actually a compensatory response
of the body to force kinins out of the lungs.

chronic generalized pain and wishes to be evaluated for
,fibromyalgia and chronic pain syndrome. A thorough history
and physical is conducted, and the findings are negative. The
patient is not taking any medications, has no allergies to
medicines, and has a negative past medical history.

recommendations -
The most noninvasive approach to assessing generalized pain
that seems to have no etiologic physical findings of chronic
fatigue, chronic pain syndrome, or fibromyalgia is to further
assess the patient's sleep history. Lack of adequate sleep has
been linked to myalgias and chronic pain. Often a vicious cycle
occurs in which the pain induced by lack of sleep then causes
inability to sleep and so on.

of his diabetes medications. Though the patient is taking oral
medications, his blood sugar levels continue to increase, and a

made from pigs. If that is the case, I cannot take it due to my
faith."
, Which response should be given to this patient? Correct

now synthetically made -

insulin, and others are synthetic analogs of natural human
insulin. It is appropriate to provide the patient with information
that will decrease his concerns about breaching his religious
beliefs.
