The resistance against which the left ventricle must pump to eject its volume is: - correct answer -
systemic vascular resistance.
When the tricuspid valve is open, central venous pressure reflects the filling pressure in the: - correct
answer -right ventricle.
,Tachycardia is dangerous for the patient with ischemic heart disease because of: - correct answer -
compromised cardiac output.
During initial examination of a critical care patient, the nurse observes wide and convex nails and
bulbous fingertips. This is evidence of: - correct answer -central cyanosis.

pacemaker. "Loss of capture" is seen on the ECG. Which nursing intervention may correct this situation?

In analyzing the ECG strip, the nurse notices a spike before each QRS complex. The patient's heart rate is
70 beats/min. This phenomenon is reflective of - correct answer -b. pacing artifact; the pacemaker is
sensing and capturing.

surgery? - correct answer -embolization that can be done to secure the lesion without surgery. When
the condition is more stable, an operation might be considered if needed.

blood pressure readings are usually approximately 140/90 mm Hg. The nurse recognizes the
characteristics of: - correct answer -metabolic syndrome.
To reverse the hyperglycemic hyperosmolar state, the nurse will first prepare to administer: - correct
answer -fluids

for the administration of: - correct answer -vasopressin
In the syndrome of inappropriate antidiuretic hormone (SIADH), the physiological effect is: - correct
answer -dilutional hyponatremia, reducing sodium concentration to critically low levels.
Which assessment findings would indicate fluid volume excess? - correct answer -edema, auscultation of
a third heart sound, crackles in lungs, bounding pulses, AMS, olguria, HTN
, The report of a renal patient's laboratory results shows that the blood urea nitrogen (BUN) level is less
than 25 mg/dL. To fully understand the patient's renal status, the nurse must consider this value along
with: - correct answer -c. creatinine level.
To determine whether edema in a patient's hands is due to circulatory compromise or another cause,
the nurse might: - correct answer -elevate the patient's extremities for 1 hour and observe the degree of
edema still present.
Hypovolemia causes tachycardia and : - correct answer -hypotension.
To avoid the complications that can result from administering furosemide (Lasix) to stimulate urinary
output, the nurse will carefully monitor: - correct answer -levels of electrolytes, especially potassium.

phase of acute kidney injury (AKI)? - correct answer -Intermittent hemodialysis
What are complications of continuous renal replacement therapy (CRRT)? - correct answer -Air
embolism, decreased inflow pressure, electrolyte imbalance
Which electrolytes pose the most potential hazard if not within normal limits for the person with acute
kidney failure? - correct answer -Potassium and calcium
