Self-Assessment Questions
Answers and explanations to these questions can be found
at the end of the chapter.
1. J.T. is a 68-year-old woman returning to her primary
care practitioner’s office to review the results
of her most recent dual-energy x-ray absorptiometry
(DEXA) scan. Her physician reports that her lumbar
spine T-score is -2.1 standard deviations (SDs)
(Z-score -1.1). The physician also reports that J.T. has
a World Health Organization (WHO) Fracture Risk
Assessment Tool (FRAX) score of 12% for major
osteoporotic fracture and 4% for hip fracture. Which
is best for J.T.’s physician to consider to preserve her
bone density?
A. Initiate high-dose vitamin D (50,000 international
units) weekly for 8 weeks and then 2000 units
daily thereafter.
B. Initiate calcium carbonate plus vitamin D (600
mg elemental plus 400 international units) twice
daily.
C. Initiate alendronate 35 mg weekly plus calcium/
vitamin D supplementation.
D. Initiate alendronate 70 mg weekly plus calcium/
vitamin D supplementation.
- Answer: D
According to her DEXA scan results, the patient would
traditionally be classified as having osteopenia in her
lumbar spine. In many cases, this would require her to be
treated only with calcium and vitamin D supplementation.
However, because her 10-year risk of a hip fracture is
greater than 3% with the FRAX tool, the NOF would consider
this patient to have osteoporosis and recommend that
she receive antiresorptive therapy. Of the choices, alendronate
is the only agent to have antiresorptive properties,
and of the two doses, 70 mg once weekly is recommended
(Answer D is correct; Answers A–C are incorrect).
Alendronate 35 mg once weekly is considered a prevention
dose for bisphosphonates.
- D.M. is a 72-year-old woman presenting to her primary
care provider for a routine follow-up. At the
visit, her provider discusses with her that she has been
taking alendronate 70 mg once weekly for the past 5
years for osteoporosis (L2/L3 compression fracture
post-fall). The physician would like to discontinue
the medication and choose a different medication to
maintain her bone mineral density (BMD). At her last
dual-energy x-ray absorptiometry (DEXA) scan, the
patient’s T-scores were -2.6 and -1.8 at the lumbar
spine and hip, respectively. These values are relatively
unchanged from her baseline. She has no renal
or hepatic complications, and her metabolic profile is
within normal limits. Which is best for the patient to
replace alendronate?
A. Risedronate 150 mg by mouth once per month.
B. Raloxifene 60 mg by mouth once per day.
C. Teriparatide 20 mcg subcutaneous injection once
per day.
D. Denosumab 60 mg subcutaneous injection once
every 6 months.
- Answer: D
The patient should restart therapy but change to a nonbisphosphonate
antiresorptive agent. Using an agent
for osteoporosis for this patient is important because of
her history of osteoporosis with fracture. Continuing a
bisphosphonate is an option, but the likelihood of a serious
adverse event (MRONJ [medication-related osteonecrosis
of the jaw], atypical femur fracture) increases with duration
of bisphosphonate use. Reducing the dose would not be
appropriate for secondary fracture prevention. Although
raloxifene is efficacious for secondary fracture prevention,
its usefulness is more for preventing breast cancer in
women at high risk, and it is not cost-effective to use routinely
for fracture prevention. Denosumab is the best option
for this patient because it will maintain the same efficacy
as a bisphosphonate for fracture prevention (Answer D is
correct; Answers A–C are incorrect). Unfortunately, we do
not yet know whether the risk of serious adverse events
is increased with the duration of sequenced medication
use (i.e., bisphosphonate to RANKL inhibitor). An anabolic
agent should be reserved for future use, more severe
disease, lack of response, and/or contraindication to antiresorptive
therapies.
- C.A. is a 69-year-old woman with rheumatoid arthritis
(RA). She is treated with oral methotrexate 15
mg once weekly, prednisone 10 mg once daily, and
naproxen 500 mg twice daily as needed. On returning
for a follow-up with her rheumatologist, she is
instructed to decrease prednisone to 7.5 mg once daily
for another 6 months. A recent DEXA scan reveals an
11% decrease in her lumbar spine since her DEXA
about 1 year ago. According to the American College
of Rheumatology (ACR), which approach is best to
prevent osteoporosis?
A. No intervention is required because the patient is
premenopausal.
B. Administer calcium carbonate 500 mg plus cholecalciferol
400 units twice daily.
C. Administer risedronate 150 mg monthly plus calcium
and cholecalciferol supplementation.
D. Administer raloxifene 60 mg once daily plus calcium
and cholecalciferol supplementation.
- Answer: C
According to the latest edition of the ACR’s guidelines for
managing glucocorticoid-induced osteoporosis, bisphosphonates
should be used for patients older than 40 with
moderate fracture risk (according to Z-score) if they are
using 7.5 mg or more of prednisone daily for more than
6 months. Because the patient meets these criteria, risedronate
150 mg monthly plus calcium and vitamin D supplementation is warranted (Answer C is correct;
Answers A, B and D are incorrect).
- F.R. is a 62-year-old woman with RA. She currently
uses etanercept 50 mg subcutaneously once weekly
and ibuprofen 600 mg every 6 hours as needed for
pain. At her latest visit to her primary care physician’s
office, she states that she will be traveling abroad later
this year and needs typhoid vaccination. Which is
most appropriate for her at this time?
A. Hold etanercept for 1 month; then vaccinate with
intramuscular Typhim Vi.
B. Start vaccination today with oral typhoid vaccine
(Vivotif).
C. Vaccinate today with intramuscular typhoid vaccine
Typhim Vi.
D. She is not a candidate for typhoid vaccination.
- Answer: D
Patients with RA receiving bDMARDs should not be
administered live vaccines such as oral typhoid. The intramuscular
typhoid vaccination is an inactivated vaccine
and is therefore safe to administer in patients receiving
bDMARDs. It is unnecessary to hold biologics before vaccination
with an inactivated vaccine (Answer D is correct;
Answers A–C are incorrect).
- A.T. is a 26-year-old woman who presents to a rheumatologist
after being given a diagnosis of RA. She
has symptoms in her elbows, knees, and hips and
easily becomes fatigued throughout the day. She has
difficulty dressing in the morning and has missed 10
days of work in the past 90 days because of her symptoms.
Her laboratory results suggest RA, and she has
no evidence of blood, liver, or kidney disease. She
is married but does not plan to have children in the
foreseeable future. Her medical history is significant
for menorrhagia, for which she has been using a lowdose
ethinyl estradiol/norgestimate monophasic pill
for the past 3 years. Which medication would be best
for the patient, according to the 2015 ACR treatment
recommendations?
A. Methotrexate 10 mg by mouth once weekly plus
folic acid 1 mg once daily.
B. Leflunomide 10 mg by mouth daily.
C. Adalimumab 40 mg subcutaneously every other
week.
D. Tofacitinib 5 mg by mouth twice daily.
- Answer: A
For this patient, the ACR 2015 treatment recommendations
encourage providers to use methotrexate as a first-line
agent for patients presenting within the first 3 months of
diagnosis. Although leflunomide may be an option, it is
recommended as an add-on to methotrexate if monotherapy
insufficiently controls the patient’s symptoms. A TNF
inhibitor such as adalimumab could also be an option and
would have been an option for this patient using the 2012
guideline update, but it has been moved to second line,
after failure of methotrexate, for the 2015 iteration (Answer
A is correct; Answers B-D are incorrect). The JAK inhibitor
tofacitinib is recommended for disease-naive patients
(less than 6 months) whose second-line measures fail or
for disease-experienced patients (more than 6 months) in
whom at least a TNF inhibitor fails.
- J.P. is a 34-year-old man with a medical history significant
for psoriasis. For the past 15 years, he has
been treated successfully with hydrocortisone cream
and moisturizers, rarely requiring oral systemic corticosteroids.
Today, he presents to his primary care
physician’s office with a worsening joint pain in his
hands and elbows. He says the pain is minimal (2/10),
but annoying. He has been receiving sufficient pain
relief from naproxen 500 mg twice daily as needed
but wonders if he could be doing more. On physical
examination, he has actively inflamed joints in his left
hand. His physician performs some radiographic evaluations,
which reveal signs of axial disease, and the
physician determines that J.P.’s symptoms are likely
caused by psoriatic arthritis (PsA). Given the patient’s
presentation, which is the best regimen for treating his
arthritic symptoms?
A. Continue naproxen 500 mg twice daily as needed.
B. Initiate sulfasalazine 500 mg twice daily.
C. Initiate etanercept 50 mcg twice weekly.
D. Initiate etanercept 50 mcg twice weekly plus sulfasalazine
1000 mg three times daily.
- Answer: A
According to the ACR and GRAPPA, patients with minimal
to no functional limitations from PsA should be treated
only with NSAIDs or other analgesics. When the symptoms
progress to moderate severity and affect the patient’s
activities of daily living, or when the symptoms do not
respond to simple analgesics, providers should consider
adding either a DMARD (e.g., sulfasalazine) or a biologic
agent (e.g., etanercept). Combination DMARD and biologic
agent should be reserved for patients with severe disease or
for those whose condition does not respond to either agent
alone (Answer A is correct; Answers B-D are incorrect).
- J.O. is a 76-year-old woman with a history of type 2
diabetes and chronic stable angina (medically managed).
She has bilateral knee osteoarthritis (OA) pain
that has not been sufficiently controlled with physical
therapy or acetaminophen 1000 mg every 6 hours. She
cannot perform many activities of daily living because
she requires a walker, which considerably impairs her
mobility. Which regimen is best to help alleviate the
patient’s chronic pain?
A. Meloxicam 7.5 mg once daily.
B. Topical diclofenac 1% gel.
C. Ketorolac 10 mg every 6 hours.
D. Morphine sulfate extended release 15 mg twice
daily.
- Answer: B
For this patient, the next best choice for pain relief is topical
diclofenac 1% gel. The ACR 2012 guidelines do not recommend
the routine use of opiate analgesia for OA pain. In
addition, given her history of ischemic heart disease, she should avoid using meloxicam or oral diclofenac because
of an FDA report regarding NSAID use and risk of CV
events. Although diclofenac gel is an NSAID, its topical
application limits the amount of systemic absorption and
possibly systemic adverse events (Answer B is correct;
Answers A, C and D are incorrect). Patients who use topical
NSAIDs are at a higher risk of dermatologic reactions
than those who use systemic NSAIDs.
- T.Q. is a 29-year-old woman without obesity who has
been treated with hydroxychloroquine for systemic
lupus erythematosus (SLE) for the past 3 years. Her
current dose is 400 mg once daily (about 5.4 mg/kg).
She speaks with her pharmacist, who asks whether she
has been receiving regular ophthalmologic screenings
for patients chronically treated with hydroxychloroquine.
The patient has never had her eyes checked.
Which would be the best recommendation for this
patient’s current and future ophthalmologic screening?
A. Initial screening now and then every 5 years.
B. Initial screening now and then annually thereafter.
C. Initial screening now and then annually starting
at year 5.
D. Initial screening now and then every 6 months
starting at year 5.
- Answer: B
Even though the patient has used hydroxychloroquine for
less than 5 years, her current daily dose is greater than
5 mg/kg/day, placing her in a higher-risk category for
hydroxychloroquine-related ocular complications. People
in the major risk category should have a baseline, followed
by annual, funduscopic examination. (Answer B is correct;
Answers A, C and D are incorrect)
- R.V. is a 42-year-old woman with a significant history
of depression and schizophrenia. Her current drug regimen
is ziprasidone 40 mg twice daily and selegiline
transdermal 6 mg/24 hours. Her symptoms are consistent
with fibromyalgia syndrome, but she has been
reluctant to start treatment until now because she was
afraid it would interfere with her other mental health
medications. However, the symptoms have worsened
during the past 6 months, and she now asks to begin
therapy. Which medication would be the best for R.V.
to begin taking?
A. Nortriptyline 25 mg once daily in the evening.
B. Gabapentin 100 mg twice daily.
C. Pregabalin 75 mg twice daily.
D. Duloxetine 60 mg once daily.
- Answer: C
The patient would best begin treatment with pregabalin
75 mg twice daily. Although all the medications listed are
appropriate for treating fibromyalgia syndrome, several
issues need to be considered. Nortriptyline and duloxetine
would create a significant drug-drug interaction with
transdermal selegiline because it inhibits both monoamine
oxidase A and monoamine oxidase B (nonselective), most
likely resulting in hypertensive crisis and/or serotonin syndrome.
However, this is not true for oral selegiline. Oral
selegiline at a dose of 5 mg twice daily maintains specificity
to inhibit monoamine oxidase B, which is primarily
responsible for monoamine oxidase activity in platelets
and the brain. Because of this selectivity, when used at
approved doses, oral selegiline and other serotonergics
pose no increased risk of serotonin syndrome. The gabapentin
dose is too low for the patient and would most likely
not have a clinically significant change in her symptoms.
The target dose for gabapentin for fibromyalgia is 1800–
2400 mg daily (divided three times). (Answer C is correct;
Answers A, B and D are incorrect)
- L.L. is a 58-year-old man with chronic tophaceous
gout and stage 4 chronic kidney disease (CKD). He
reports only taking over-the-counter (OTC) ibuprofen
for gout in the past but states he was told to stop
because it “hurt his kidneys.” He states that the tophi
sometimes bother him and that he has two or three
attacks per year. The patient has 10–12 alcoholic
drinks a day and regularly consumes a lot of meat proteins.
In addition to dietary counseling, which therapy
is best to decrease tophi and prevent gouty attacks in
this patient?
A. No therapy is required until he has two or more
gouty attacks in a 12-month period.
B. Administer allopurinol 50 mg once daily, slowly
titrated over the next few months.
C. Administer allopurinol 300 mg once daily, slowly
titrated over the next few months.
D. Administer colchicine 0.6 mg three times weekly.
- Answer: B
The patient has CKD, thereby limiting the choice of medications
and doses that can be used to prevent recurrent
gouty attacks. The patient is a candidate for gout prevention
and treatment of hyperuricemia. The number of attacks per
year does not factor in when initiating therapy. Colchicine
does not affect tophi formation. Xanthine oxidase inhibitors
(allopurinol first line) are the drug of choice for patients
with tophi. The ACR guidelines state that in patients with stage 4 CKD or worse, allopurinol therapy can be initiated
at 50 mg/day, increasing the dose every 2–5 weeks to
achieve the desired uric acid concentrations; doses greater
than 300 mg/day are allowed but with appropriate patient
education and monitoring for toxicity (Answer B is correct;
Answers A, C and D are incorrect)
Patient cases
- F.R. is a 74-year-old woman with a history of a right hip replacement after a fall and fracture. In addition to her
hip fracture, she has a history of type 2 diabetes (most recent hemoglobin A1C 7.3%) and hypothyroidism (current
thyroid-stimulating hormone concentration [TSH] 0.1 mIU/L), for which she receives treatment. A dual-energy
x-ray absorptiometry (DEXA) revealed F.R.’s T-score at her femoral neck as -2.7. The Z-score associated with her
femoral neck T-score was -2.1. Her physician believes this was a fracture secondary to drug-induced bone density
loss. Which medication most likely contributed to her bone mineral density (BMD) loss and fracture?
A. Metformin.
B. Glipizide.
C. Levothyroxine.
D. Lovastatin.
- Answer: C
Many medications contribute to BMD loss by either accelerating
bone resorption or inhibiting osteogenesis. For this
patient, levothyroxine most significantly affected her BMD
by speeding up the bone resorption process (Answer C is
correct; Answers A, B, and D are incorrect). Excessive
thyroid hormone supplementation or drug-induced hyperthyroidism
places patients at risk of OA and fracture.
Practitioners should be cognizant of TSH and free thyroid
hormone concentrations, treating patients to a euthyroid
state and a TSH concentration of around 2.0–3.0 mIU/L.
This suggestion does not apply to patients who require
maximal thyroid hormone suppression (i.e., have a history
of thyroid cancer).
- M.J. is a 61-year-old white woman (height 65 inches, weight 68 kg) who consults with her pharmacist about how best
to preserve her bone density and prevent a fracture. The patient’s medical history is significant for a maternal hip
fracture (mother was age 71). Her 10-year risk of a major osteoporotic fracture (FRAX score) is estimated at 19%
and, for the hip, 6.3%. From these results, which is the best course of action for the pharmacist to take?
A. Recommend that the patient contact her primary care provider to request a DEXA scan.
B. Recommend that the patient contact her primary care provider to request a DEXA scan and start calcium
plus vitamin D supplementation.
C. Recommend that the patient contact her primary care provider to request a DEXA scan, start calcium plus
vitamin D supplementation, and start taking a bisphosphonate.
D. Recommend that the patient NOT have a DEXA scan and that she begin calcium plus vitamin D supplementation
and start taking a bisphosphonate.
- Answer: B
The patient in question has not yet had a DEXA scan or
received a T-score for her lumbar spine or femoral neck.
Therefore, antiresorptive therapy is unwarranted until
the results are available. She should begin treatment with
calcium and vitamin D to preserve BMD. If the DEXA
scan reveals osteopenia (T-score between -1.0 and -2.5),
bisphosphonate therapy should be initiated because the
patient’s risk of hip fracture in the next 10 years is greater
than 3% (Answer B is correct; Answers A, C and D are
incorrect)
- O.T. is a 65-year-old woman given a diagnosis of osteopenia after a scheduled DEXA scan. Her other medical conditions
include type 2 diabetes, irritable bowel syndrome, gastroesophageal reflux disease, and migraine headaches.
Her medications include metformin, pantoprazole, amitriptyline, and sumatriptan. She regularly participates in
aqua aerobics and walking and uses laundry detergent bottles to strengthen her upper body. Her dietary calcium
intake is limited to 1 glass of milk (8 oz each) per day. She has not yet started calcium, but she would like to add it
to her medications and daily supplements. Which OTC calcium regimen is best to recommend for her?
A. Calcium carbonate 600 mg/vitamin D 500 international units 1 tablet twice daily with food.
B. Calcium carbonate 600 mg/vitamin D 500 international units 2 tablets twice daily with food.
C. Calcium citrate 315 mg/vitamin D 500 international units 1 tablet twice daily.
D. Calcium citrate 315 mg/vitamin D 250 international units 2 tablets twice daily.
- Answer: D
Because the patient has an extensive history of GI disease
and receives chronic therapy with a PPI, she will most
likely benefit from treatment with a calcium citrate supplement.
Calcium carbonate salts, when administered with an
acid-suppressing agent, yield less calcium availability than
a calcium citrate formulation. However, when converting
from a calcium carbonate tablet to a calcium citrate tablet,
the “serving size” is usually doubled, and the patient
requires 2 tablets of calcium citrate to equal the elemental
calcium in 1 calcium carbonate tablet (Answer D is correct;
Answers A–C are incorrect) The maintenance therapy of
vitamin D3 is 1000-2000 IU daily.
- E.U. is a 58-year-old woman with a medical history significant for primary progressive multiple sclerosis with
severe limitation, for which she spends most of her time in bed or lying on a couch. She tries to ambulate but cannot
do so without a walker and/or assistance. Her DEXA scan reveals osteoporosis of the lumbar spine, and she
now requires treatment. She has no history of fracture. Her provider deems her disease in the “high-risk” category.
She already takes 1200 mg of calcium carbonate daily (600 mg twice daily) and 800 units of vitamin D (400 units
twice daily). Which is best for E.U. to prevent vertebral fracture?
A. Zoledronic acid 5-mg infusion once yearly.
B. Risedronate 150-mg tablet once monthly.
C. Raloxifene 60-mg tablet once daily.
D. Romosozumab 210 mg once monthly.
- Answer: A
This patient’s inability to be mobile (and possibly upright)
drastically limits her medication choices for the primary
prevention of an osteoporotic fracture. Zoledronic acid
seems to be the most appropriate agent because data analyses
support its ability to maintain vertebral bone density, and patients do not have to adhere to strict post-dosing
restrictions when using it. Risedronate is appropriate if the
patient can remain upright for 30–60 minutes, but this may
be too physically demanding for the patient. Romosozumab
is reserved for patients as a later line option would be a
poor choice for the patient. Raloxifene has a high incidence
of venous thromboembolism and, in conjunction with the
patient’s limited mobility, might increase her risk of a
venous thromboembolism (Answer A is correct; Answers
B-D are incorrect)
- K.W. is a 37-year-old female executive (height 64 inches, weight 70 kg [155 lb]) with RA (diagnosed 3 months ago),
type 2 diabetes, and hypertension who smokes cigarettes. Her basic metabolic profile and complete blood cell
count (CBC) are all within normal limits. Her RF is about 4 times the upper limit of normal; she has elevated anticyclic
citrullinated peptide antibody values and ESR (high disease activity). Her radiographs reveal evidence of
bony erosions. During the 2 months before her diagnosis, she had severe functional limitation, sometimes missing
work because she could not prepare herself in a timely fashion. She is married and has two children with no plans
for additional children. According to the ACR recommendations, which medication regimen is best for K.W.?
A. Hydroxychloroquine 400 mg once daily and folic acid 1 mg daily.
B. Methotrexate 10 mg once weekly titrated to a target dose of 20–25 mg once weekly and folic acid 1 mg daily.
C. Methotrexate 10 mg once weekly, folic acid 1 mg daily, and infliximab 3 mg/kg every 8 weeks.
D. Methotrexate 10 mg once weekly, folic acid 1 mg daily, and anakinra 100 mg daily.
- Answer: B
The 2015 update to the ACR recommendations for managing
RA advocate DMARD monotherapy, particularly
methotrexate, for all patients regardless of their disease
severity and time since symptom onset. For this patient,
Answer B is correct. She may combine TNF inhibitors
with methotrexate, but this would be only after she cannot
achieve disease remission with methotrexate alone.
Hydroxychloroquine alone is not a preferred DMARD
monotherapy, and combining anakinra with methotrexate
would be inappropriate; anakinra is not included in the
guidelines as an appropriate biologic option because of its
lack of efficacy in patients with RA (Answer B is correct;
Answers A, C and D are incorrect).
