1. A patient with anterior epistaxis has been treated with 20 minutes of direct pressure to the
cartilaginous portion of the nose. Following pressure the patient is instructed to gently blow the
nose. Expected findings in the patient who has been successfully treated include all of the following
except a:
2. Kevin is a 14-year-old male who presents for evaluation of a fever of 102.5° F and significant right
ear pain. He appears quite ill and says he feels nauseous. Otoscopic evaluation reveals pain to
palpation, a very erythematous and bulging tympanic membrane with bullous myringitis. The
AGACNP knows that antibiotic therapy must be selected to cover:
3. P.M. is a 71-year-old gay male patient who presents as an outpatient for evaluation of increasing
shortness of breath. The diagnostic evaluation ultimately supports a diagnosis of community
acquired pneumonia. The AGACNP appreciates right middle lobe consolidation on chest radiography.
Pending sputum cultures, empiric antibiotic therapy must be initiated to cover which organism?
4. The AGACNP is caring for a patient who is quite ill and has developed, among other things, a
large right sided pleural effusion. Thoracentesis is sent for pleural fluid analysis. While evaluating the
fluid analysis, the AGACNP knows that a fluid identified as a(n) __________ is the least worrisome
type.
5. Mrs. Miller is transported to the emergency department by paramedics. She is having profound,
unremitting chest pain, is diaphoretic and pale. She has jugular venous distention and a widened
pulse pressure. Suspecting ascending aortic aneurysm, the AGACNP order which test to confirm the
diagnosis?
6. Certain subgroups of the elderly population are at an increased risk for rapid deterioration and
long-term care placement. Which of the following is not considered a high risk factor for long term
care placement?
7. Which of the following is the greatest risk factor for vascular dementia?
8. J.R. is a 55-year-old male who presents for a commercial driver’s license physical examination
with a blood pressure of 170/102 mm Hg. He has no medical history and is without complaint. Which
of the following findings constitutes hypertensive urgency?
9. Because of the commonly recognized adverse effects of atypical antipsychotics, annual
laboratory assessment for patients taking these medications should include a:
10. K.R. presents for an evaluation of eye discomfort. He works in a fabricating shop for a custom
automobile restoration company and while working he felt like something flew into his eye. He was
wearing eye protection at the time but still has the sensation that something is there. Physical
examination is significant for some tearing and he reports a persistent sense of something in his eye.
Which of the following is not indicated in the diagnostic evaluation?
11. D.E. is a 41-year-old female who had lumbar surgery two days ago to repair a ruptured nucleus
pulposus. She has been doing well postoperatively but today is complaining of resting fatigue and
some shortness of breath at rest. In ruling out a pulmonary embolus the AGACNP first orders a:
12. Mr. Nixon is being treated with unfractionated heparin infusion for acute pulmonary embolus. In
order to avoid a potentially fatal complication of heparin infusion, the AGACNP monitors:
,13. Differentiating vertigo from near-syncope and ataxia is one of the goals of history-taking when a
patient presents as “dizzy.” The AGACP knows that vertigo is the problem when the patient reports
the primary symptom as:
14. Mr. Banks has been admitted for surgical resection of a metastatic tumor, during surgery it is
discovered that he has widespread, diffuse metastasis throughout the abdomen. Surgery is no longer
an option, and his oncologist says that chemotherapy is unlikely to produce any meaningful benefit.
Mr. Banks is concerned that his sons will not support a transfer to comfort care. The AGACNP advises
that he:
15. Mr. Wilkerson is a 77-year-old male who is being evaluated and treated for his cardiogenic pain.
His vital signs are as follows: Temperature of 99.1° F, pulse of 100 bpm, respirations of 22 bpm, and
blood pressure of 168/100 mm Hg. A 12-lead ECG reveals deep ST segment depression in leads V 3-V6.
The AGACNP recognizes which of the following as a contraindication to rTPA therapy?
16. A 71-year-old patient is recovering from a particularly severe exacerbation of chronic obstructive
pulmonary disease. He has been in the hospital for almost two weeks and was on mechanical
ventilation for 7 days. While discussing his discharge plan he tells you that he is really going to quit
smoking this time. He acknowledges that he has been "sneaking" cigarettes in the hospital for two
days, but he has established a timeline to decrease the number of cigarettes daily. According to his
plan his last cigarette will be the last day of the month. This patient’s behavior is consistent with
which stage of the Transtheoretical Model of Change?
17. While assessing a patient with a known psychiatric history, the AGACNP knows that the primary
difference between a psychotic and neurotic disorders is:
18. L.T. is an 85-year-old male who is admitted for evaluation of profound diarrhea that has
produced significant dehydration. He also complains of being very tired lately, and feeling like he is
going to vomit all of the time. His vital signs are significant for a pulse of 41 b.p.m. and a blood
pressure of 90/60 mm Hg. A gastrointestinal evaluation including stool for blood, white blood cells,
and ova and parasites is negative. He insists that he has not started any new medications or made
any diet changes; the only thing new is that he got new eye drops for his glaucoma. The AGACNP
correctly assumes that his new eye drops are:
19. Janice is a 19-year-old female who presents to the emergency department via ambulance. She is
pale, diaphoretic, agitated, and convinced she is having a stroke. Her vital signs include a
temperature of 98.9° F, pulse of 114 beats per minute, respirations of 32 breaths per minute, and a
blood pressure of 110/74 mm Hg. Diagnostic evaluation is negative and Janice is diagnosed with an
acute panic attack. The initial treatment of choice is:
20. Lorraine is a 41-year-old female who presents for an asthma follow-up visit. She says she feels
very well, has almost no daytime symptoms, and is using her inhaled corticosteroid medication daily
as prescribed. Her PEFR is 85% of her personal best. The best approach to this patient is to:
21. Mr. Owen is a 37-year-old patient who has been admitted for surgical resection of a malignant
tumor in his lung. His physical recovery has been uneventful and he is being prepared for discharge.
While discussing his ongoing cancer therapy with Mr. Owen, the AGACNP determines that he has
experienced persistent, excessive anxiety and worry almost every day for more than one year. What
other aspect of Mr. Owen's psychosocial history would be required to made a diagnosis of
generalized anxiety disorder?
,22. Kevin T. is a 49-year-old male who is being discharged after hospitalization for an acute inferior
wall myocardial infarction. This is his first hospitalization and his first chronic medical diagnosis. Aside
from his elevated cardiac isoenzymes and troponins, his laboratory profile was essentially within
normal limits. The only apparent cardiac risk factor is an LDL cholesterol of 200 mg/dL. Initiating an
HMG-CoA reductase inhibitor is an example of which level of prevention for Kevin?
23. You are evaluating a patient who has been admitted to the emergency room after being arrested
for starting a fight in a local sports' bar. The patient is now being cooperative, but reports that he has
been in treatment for PTSD for months. He has been prescribed fluoxetine but has not noticed any
improvement in symptoms, and now has been arrested for violence. The AGACNP knows that the
next step in medication management is likely to include:
24. Mrs. Salter is an 81-year-old lady who presents for evaluation of near-syncopal episodes. Her 12-
lead ECG, complete blood count, and comprehensive metabolic panel are all essentially normal. A
urinalysis shows some trace protein but is otherwise normal. A 24-hour rhythm monitor
demonstrates rare premature ventricular contractions. Mrs. Salter has been in good health and had
her first episode at her aerobics class. She only gets lightheaded when she exerts herself. Her heart
auscultates for a grade III/VI systolic crescendo-decrescendo murmur at the second intercostal space,
right sternal border. The AGACP considers that the likely cause of the syncope is:
25. Who among the following patients is at greatest risk for a pulmonary embolus?
26. Mrs. Birdsong is an 85-year-old female who has been admitted for surgical repair of a hip
fracture. She is in remarkably good spirits and is quite talkative. She readily answers all of the
questions on her intake assessment, and readily acknowledges information provided during her
room orientation. Later while talking with the patient's son the AGACNP learns that the patient has
had significant cognitive impairment for a few years. She has virtually no short term memory, but
compensates by confabulating. Her son says she is generally very happy as long as there is no change
in her day to day routine. This history is most consistent with which form of dementia?
27. Mrs. Radovich is an 80-year-old female with a variety of chronic medical conditions which are
reasonably well controlled. She generally enjoys a good quality of life and is active with her family.
Today her only concern is that she is having problems with her vision. She notices that while trying to
look at pictures of her great grandchildren she can’t seem to focus on their faces. She also reports
increased trouble reading—she cannot seem to see the words that she is looking at, and her reading
glasses do not help. Further evaluation of Mrs. Radovich should include assessment with:
28. R.J. is a 55-year-old female who presents with acute onset left sided facial pain and an inability
to move the left side of her face. She cannot smile, raise her eyebrow or even close her left eye, The
immediate approach to this patient should include:
29. A 78-year-old male present for a physical examination. He has no discomfort or complaints other
than a general decrease in vision, but it helps when he puts things under a bright light to read. He
admits that while driving at night the streetlights appear to be a bit distorted and his night vision is
pretty poor. Given the likely diagnosis, the AGACNP expects which of the following physical findings?
30. Jason is a 46-year-old male who is being managed for sepsis. He has HIV/AIDS and has had a
prolonged hospitalization characterized by a variety of complications. He was extubated 3 days ago
but continues gastric decompression with a nasogastric tube(NGT), total parenteral nutrition and
antibiotic therapy via a central venous catheter, and urinary drainage via a Foley catheter. He
continues to demonstrate consistent low grade fevers but all points of insertion of his tubes are
, normal to inspection, a chest radiograph demonstrates improvement of his pneumonia, and his
urinalysis shows no bacteria, leukocytes, or nitrites. The AGACNP should next order:
31. The interpretation of a chest radiography should follow a systematic approach to ensure that all
vital structures are evaluated and important clinical findings are not missed. The last thing to be
assessed when looking at chest radiography should be the _____________:
32. The Short Confusion Assessment Method (Short-CAM) is a widely used four item tool that
assesses delirium in the hospitalized patient. It includes observation of all of the following except:
33. Ms. Yang has been hospitalized for 5 days for the management of a gastrointestinal bleeding. She
appears to have stabilized hemodynamically, but today she had a temperature of 101.9° F and chest
radiography demonstrates a diagnosis of pneumonia. The AGACNP knows that the diagnostic
evaluation for hospital acquired pneumonia for all patients must include:
34. Most psychosocial theories of aging center around the core concept that successful aging
requires acceptance of a series of changes or losses that predictably occur later in the life span. The
theory that specifically addresses coming to terms with the inevitability of death is known as:
35. All of the following conditions are risk factors for pulmonary embolus except:
36. A patient is diagnosed with acute descending aortic aneurysm and hypertension should be
immediately started on which medication pending surgical evaluation?
37. Jason is a 27-year-old with a long history of intermittently controlled asthma. He is currently
prescribed Advair daily with albuterol as needed for symptoms. Today he presents to the emergency
department with cough and wheezing and difficulty catching his breath. His FEV 1 is 51% at the time
of presentation. He is given alternating albuterol and ipratropium nebulizer treatments along with
oral prednisone. After one hour his FEV1 has increased 65%. The appropriate disposition for Jason at
this point is:
38. A patient in the intensive care unit suddenly becomes tachypneic and dyspneic. The physical
examination reveals pale, cool, clammy skin and an arterial blood gas demonstrates hypocapnea and
hypoxia. Pulmonary artery pressure demonstrates a pattern consistent with obstructive shock. The
AGACNP knows that which of the following causes of this presentation is most likely?
39. Mr. Bowers is an 81-year-old male who is being terminally extubated at the request of his family
due to the presence of a large subdural hematoma with a shift; the patient is not initiating
respirations on his own and the prognosis is very poor. After he is extubated he begins to initiate his
own respirations and 24 hours later has not expired yet. The decision is made to leave him in the
hospital on a general medical floor rather than transfer to another facility for hospice. Which of the
following is the best indicator that the patient’s death is imminent?
40. A patient is newly admitted to your service for open reduction and internal fixation of the left
hip. She seems very down, and as you talk with her you realize that her mood is not just related to
her hip fracture. Which of the following symptoms would not be consistent with major depressive
disorder?
41. “C” is the correct answer. Alzheimer’s dementia is statistically the most common form of
dementia and is characterized by a long trajectory that progresses to include confabulation.
Additionally, patients with this form of dementia are very reliant upon routine and may be distressed
when it is disrupted. “A” is not correct; Lewy body dementia characteristically progresses much more
quickly and produces an angry demeanor. “B” is incorrect because vascular dementia typically
