QUESTIONS AND ANSWERS SURE A+
✔✔A 6-year-old boy has been brought to the emergency department by ambulance

child was determined to be in atrial flutter and his mother is seeking an explanation from
the health care team. Which of the following points should underlie an explanation to the
mother? - ✔✔The child is experiencing a reentry rhythm in his right atrium.
✔✔A 68-year-old male complains to his nurse practitioner that when he tests his blood
pressure using a machine at his pharmacy, his heart rate is nearly always very low. At
other times, he feels that his heart is racing, and it also seems to pause at times. The
man has also occasionally had lightheadedness and a recent syncopal episode. What is
this patient's most likely diagnosis and the phenomenon underlying it? - ✔✔Sick sinus
syndrome as a result of a disease of his sinus node and atrial or junctional arrhythmias

meeting with his nurse practitioner. The patient's nurse practitioner would anticipate that
which of the following phenomena is most likely occurring? - ✔✔The conversion of
angiotensin I to angiotensin II in his lungs causes increases in blood pressure and
sodium reabsorption.
✔✔A 72-year-old woman with a recent onset of syncopal episodes has been referred to
a cardiology group by her family physician. As part of the patient's diagnostic workup,
the nurse practitioner conducting the intake assessment has ordered a Holter monitor
for 24 hours. Which of the following statements best captures an aspect of Holter
monitoring? - ✔✔Accurate interpretation of the results requires correlating the findings
with the activity that the woman was doing at the time of recording.
✔✔A nurse practitioner is teaching a student NP about the physiologic basis for
damage to the circulatory and neurological systems that can accompany hypotension.
,Which of the following responses by the student would warrant correction by the nurse
practitioner? - ✔✔"Tension and vessel thickness increase proportionately."

reveals sinus bradycardia and she is suspected of having sick sinus syndrome. Which
of the following diagnostic methods is the best choice to investigate the suspicion? -
✔✔Holter monitoring
✔✔In which of the following patient situations would a nurse practitioner be most
justified in preliminarily ruling out pericarditis as a contributing pathology to the patient's
health problems? - ✔✔A 77-year-old with diminished S3 and S4 sounds, an irregular
heart rate, and a history of atrial fibrillation
✔✔A 70-year-old male patient presents to the emergency department complaining of
pain in his calf that is exacerbated when he walks. His pedal and popliteal pulses are
faintly palpable and his leg distal to the pain is noticeably reddened. What would his
care provider's preliminary diagnosis and anticipated treatment most likely be? -
✔✔Atherosclerotic occlusive disease necessitating thrombolytic therapy
✔✔A nurse practitioner has ordered the measurement of a cardiac patient's electrolyte
levels as part of the patient's morning blood work. Which of the following statements
best captures the importance of potassium in the normal electrical function of the
patient's heart? - ✔✔Potassium is central to establishing and maintaining the resting
membrane potential of cardiac muscle cells.

hours with complaints that are preliminarily indicative of myocardial infarction. Which of
the following patients is least likely to have an ST-segment myocardial infarction
(STEMI)? - ✔✔A 71-year-old man who has moist skin, fever, and chest pain that is
excruciating when he moves but relieved when at rest
✔✔An 81-year-old male resident of a long-term care facility has a long-standing
diagnosis of heart failure. Which of the following short-term and longer-term
,compensatory mechanisms is least likely to decrease the symptoms of his heart failure?
- ✔✔AV node pacemaking activity and vagal nerve suppression
✔✔A 22-year-old male is experiencing hypovolemic shock following a fight in which his
carotid artery was cut with a broken bottle. What immediate treatments are likely to
most benefit the man? - ✔✔Infusion of normal saline of Ringer lactate to maintain the
vascular space
✔✔A nurse practitioner is providing care for several patients on a medical unit of a
hospital. In which of the following patient situations would the nurse practitioner be most
likely to rule out hypertension as a contributing factor? - ✔✔A 61-year-old man who has
a heart valve infection and recurrent fever
✔✔An older adult female patient has presented with a new onset of shortness of breath,
and the patient's nurse practitioner has ordered measurement of her BNP levels along
with other diagnostic tests. What is the most accurate rationale for the nurse
practitioner's choice of blood work? - ✔✔BNP is released as a compensatory
mechanism during heart failure and measuring it can help differentiate the patient's
dyspnea from a respiratory pathology.
✔✔A formerly normotensive woman, pregnant for the first time, develops hypertension
and headaches at 26 weeks' gestation. Her blood pressure is 154/110 mm Hg and she
has proteinuria. What other labs should be ordered for her? - ✔✔Platelet count, serum
creatinine, and liver enzymes
✔✔A patient in the intensive care unit has a blood pressure of 87/39 and has warm,
flushed skin accompanying his sudden decline in level of consciousness. The patient
also has arterial and venous dilation and a decrease in systemic vascular resistance.
What is this patient's most likely diagnosis? - ✔✔Septic shock
✔✔A nurse practitioner is instructing a group of older adults about the risks associated
with high cholesterol. Which of the following teaching points should the participants try
to integrate into their lifestyle after the teaching session? - ✔✔"Your family history of
hypercholesterolemia is important, but there are things you can do to compensate for a
high inherited risk."
✔✔A 66-year-old obese man with a diagnosis of ischemic heart disease has been
diagnosed with heart failure that his care team has characterized as attributable to
systolic dysfunction. Which of the following assessment findings is inconsistent with his
diagnosis? - ✔✔Ventricular dilation and wall tension are significantly lower than normal.

amounts of mucus. Consequently, the patient's mucociliary blanket is compromised.
Which of the following changes would a care provider most reasonably anticipate as a
direct result of this change? - ✔✔Increased amounts of bacteria in the lungs. The
primary role of the mucociliary blanket is to trap foreign particles and bacteria and thus
