Question 1

A 15-year-old high school sophomore and her mother come to your clinic because the mother is concerned about her daughter's weight. You measure her daughter's height and weight and obtain a BMI of 19.5 kg/m². Based on this information, which of the following is appropriate?

Accepted Answer

The patient has a normal BMI; the range for a normal BMI is 18.5 to 24.9 kg/m². You may be able to give the patient and her mother the lower limit of normal in pounds for her daughter's height, or instruct her in how to use a BMI table.

Question 2

A 25-year-old radio announcer comes to the clinic for an annual examination. His BMI is 26.0 kg/m². He is concerned about his weight. Based on this information, what is appropriate counsel for the patient during the visit?

Accepted Answer

The patient has a BMI in the overweight range, which is 25.0 to 29.9 kg/m². It is prudent to give him information about reducing calories, fat, and cholesterol in his diet to help prevent further weight gain.

Question 3

A 30-year-old sales clerk comes to your office wanting to lose weight; her BMI is 30.0 kg/m². What is the most appropriate amount for a weekly weight reduction goal?

Accepted Answer

Based on the NIH Obesity Guidelines, this is the weekly weight loss goal to strive for to maintain long-term control of weight. More rapid weight loss than this does not result in a better outcome at one year.

Question 4

A 67-year-old retired janitor comes to the clinic with his wife. She brought him in because she is concerned about his weight loss. He has a history of smoking 3 packs of cigarettes a day for 30 years, for a total of 90 pack-years. He has noticed a daily cough for the past several years, which he states is productive of sputum. He came into the clinic approximately 1 year ago, and at that time his weight was 140 pounds. Today, his weight is 110 pounds. Which one of the following questions would be the most important to ask if you suspect that he has lung cancer?

Accepted Answer

This is important: If the patient hasn't tried to lose weight, then this weight loss is inadvertent and poses concern for a neoplastic process, especially given his smoking history.

Question 5

Common or concerning symptoms to inquire about in the General Survey and vital signs include all of the following except:

Accepted Answer

This symptom is more appropriate to the respiratory review of systems.

Question 6

You are beginning the examination of a patient. All of the following areas are important to observe as part of the General Survey except:

Accepted Answer

Blood pressure is a vital sign, not part of the General Survey.

Question 7

A 55-year-old bookkeeper comes to your office for a routine visit. You note that on a previous visit for treatment of contact dermatitis, her blood pressure was elevated. She does not have prior elevated readings and her family history is negative for hypertension. You measure her blood pressure in your office today. Which of the following factors can result in a false high reading?

Accepted Answer

A blood pressure cuff that is too tightly fitted can result in a false high reading. The other answers are important to observe to obtain an accurate blood pressure reading. JNC-7 also mentions the importance of having the back supported when obtaining blood pressure in the sitting position.

Question 8

A 49-year-old truck driver comes to the emergency room for shortness of breath and swelling in his ankles. He is diagnosed with congestive heart failure and admitted to the hospital. You are the student assigned to do the patient's complete history and physical examination. When you palpate the pulse, what do you expect to feel?

Accepted Answer

Congestive heart failure is characterized by decreased stroke volume or increased peripheral vascular resistance, which would result in a small-amplitude, weak pulse. Subtle differences in amplitude are usually best detected in large arteries close to the heart, like the carotid pulse. You may not be able to notice these in other locations.

Question 9

An 18-year-old college freshman presents to the clinic for evaluation of gastroenteritis. You measure the patient's temperature and it is 104 degrees Fahrenheit. What type of pulse would you expect to feel during his initial examination?

Accepted Answer

Fever results in an increased stroke volume, which results in a large-amplitude, forceful pulse. Later in the course of the illness, if dehydration and shock result, you may expect small amplitude and weak pulses.

Question 10

A 25-year-old type 1 diabetic clerk presents to the emergency room with shortness of breath and states that his blood sugar was 605 at home. You diagnose the patient with diabetic ketoacidosis. What is the expected pattern of breathing?

Accepted Answer

This is the expected rate and depth in diabetic ketoacidosis. The body is trying to rid itself of carbon dioxide to compensate for the acidosis. This is known as Kussmaul's breathing and is seen in other causes of acidosis as well.

Question 11

Mrs. Lenzo weighs herself every day with a very accurate balance-type scale. She has noticed that over the past 2 days she has gained 4 pounds. How would you best explain this?

Accepted Answer

This amount of weight over a short period should make one think of body fluid changes. You may consider a kidney problem or heart failure in your differential. The other reasons should be considered as well, but this amount of weight gain over a short period usually indicates causes other than excessive caloric intake. A rule of thumb for dieters is that an energy excess of 3500 calories will cause a 1-pound weight gain, if the increase is to be attributed to food intake.

Question 12

Mr. Curtiss has a history of obesity, diabetes, osteoarthritis of the knees, HTN, and obstructive sleep apnea. His BMI is 43 and he has been discouraged by his difficulty in losing weight. He is also discouraged that his goal weight is 158 pounds away. What would you tell him?

Accepted Answer

Many patients trying to change a habit are overwhelmed by how far they are from their goal. As the proverb says: "A journey of a thousand miles begins with one step." Many patients find it empowering to know that they can achieve a small goal, such as a loss of 1 pound per week. They must be reminded that this process will take time and that slow weight loss is more successful long-term. Research has shown that significant benefits often come with even a 10% weight loss.

Question 13

Jenny is one of your favorite patients who usually shares a joke with you and is nattily dressed. Today she is dressed in old jeans, lacks makeup, and avoids eye contact. To what do you attribute these changes?

Accepted Answer

It is important to use all of your skills and memory of an individual patient to guide your thought process. She is not described as sleepy. Work fatigue would most likely not cause avoidance of eye contact. Financial difficulties would not necessarily deplete a nice wardrobe. It is most likely that she is depressed or in another type of difficulty.

Question 14

You are seeing an older patient who has not had medical care for many years. Her vital signs taken by your office staff are: T 37.2, HR 78, BP 118/92, and RR 14, and she denies pain. You notice that she has some hypertensive changes in her retinas and you find mild proteinuria on a urine test in your office. You expected the BP to be higher. She is not on any medications. What do you think is causing this BP reading, which doesn't correlate with the other findings?

Accepted Answer

The blood pressure is unusual in this case in that the systolic pressure is normal while the diastolic pressure is elevated. Especially with the retinal and urinary findings, you should consider that the BP may be much higher and that an auscultatory gap was missed. This can be avoided by checking for obliteration of the radial pulse while the cuff is inflated. Although a large cuff can cause a slightly lower BP on a patient with a small arm, this does not account for the elevated DBP. Emotional upset usually causes elevation of the BP. Although a process which caused the retinopathy and kidney problems may have resolved, leaving these findings, it is a dangerous assumption that this is the sole cause of the problems seen in this patient.

Question 15

Despite having high BP readings in the office, Mr. Kelly tells you that his readings at home are much lower. He checks them twice a day at the same time of day and has kept a log. How do you respond?

Accepted Answer

It is not uncommon to see differences in a patient's home measurements and your own in the office. Presuming that this is "white coat hypertension" can be dangerous because this condition is not usually treated. This allows for the effects of a missed diagnosis of hypertension to go unchecked. It is also very difficult to judge if a patient is outwardly nervous. You should always consider that your measurements are not accurate as well, but the fact that you and your staff are well-trained and perform this procedure on hundreds of patients a week makes this less likely. Ideally, you would ask the patient to bring in his BP equipment and take a simultaneous reading with you to make sure that he is getting an accurate reading.

Question 16

You are observing a patient with heart failure and notice that there are pauses in his breathing. On closer examination, you notice that after the pauses the patient takes progressively deeper breaths and then progressively shallower breaths, which are followed by another apneic spell. The patient is not in any distress. You make the diagnosis of:

Accepted Answer

Cheyne-Stokes respiration can be seen in patients with heart failure and is usually not a sign of an immediate problem. Ataxic breathing is very irregular in rhythm and depth and is seen with brain injury. Kussmaul's respiration is seen in patients with a metabolic acidosis, as they are trying to rid their bodies of carbon dioxide to compensate. Respirations in COPD are usually regular and are not usually associated with apneic episodes.

Question 17

Mr. Garcia comes to your office for a rash on his chest associated with a burning pain. Even a light touch causes this burning sensation to worsen. On examination, you note a rash with small blisters (vesicles) on a background of reddened skin. The rash overlies an entire rib on his right side. What type of pain is this?

Accepted Answer

This vignette is consistent with a diagnosis of herpes zoster, or shingles. This is caused by reemergence of dormant varicella (chickenpox) viruses from Mr. Garcia's nerve root. The characteristic burning quality without a history of an actual burn makes one think of neuropathic pain. It will most likely remain for months after the rash has resolved. There is no evidence of physical injury and this is a peculiar distribution, making nociceptive pain less likely. There is no evidence of a psychogenic etiology for this, and the presence of a rash makes this possibility less likely as well. Because of your astute diagnostic abilities, the pain is not idiopathic.

Question 18

A 50-year-old body builder is upset by a letter of denial from his life insurance company. He is very lean but has gained 2 pounds over the past 6 months. You personally performed his health assessment and found no problems whatsoever. He says he is classified as "high risk" because of obesity. What should you do next?

Accepted Answer

The patient most likely had a high BMI because of increased muscle mass. In this situation, it is important to measure his waist. It is most likely under 40 inches, which makes obesity unlikely (even to an insurance company). It is important that you personally contact the company and explain your reasoning. Be prepared to back your argument with data. A special diet is unlikely to be of much use, and more aerobic exercise, while probably a good idea for most, is redundant for this individual.

Question 19

Ms. Wright comes to your office, complaining of palpitations. While checking her pulse you notice an irregular rhythm. When you listen to her heart, every fourth beat sounds different. It sounds like a triplet rather than the usual "lub dup." How would you document your examination?

Accepted Answer

Because this unusual beat occurs every fourth set of heart sounds, it is regularly irregular. This is most consistent with ventricular premature contractions (or VPCs). This is generally a common and benign rhythm. An irregularly irregular rhythm is a classic finding in atrial fibrillation. The rhythm is very random in character. Bradycardia refers to the rate, not the rhythm.

Quiz 4: Beginning the Physical Examination: General Survey, Vital Signs, and Pain

A 15-year-old high school sophomore and her mother come to your clinic because the mother is concerned about her daughter's weight. You measure her daughter's height and weight and obtain a BMI of 19.5 kg/m2. Based on this information, which of the following is appropriate?

A 25-year-old radio announcer comes to the clinic for an annual examination. His BMI is 26.0 kg/m2. He is concerned about his weight. Based on this information, what is appropriate counsel for the patient during the visit?
