Cardiovascular MCQ Questions Questions
Question 1 of 5
A patient's ECG lacks recognizable waveforms and is deemed to be in sinus arrest. The patient's sinus arrest may be a result of
Correct Answer: A
Rationale: Sinus arrest may result from MI, electrical shock, electrolyte disturbances, acidosis, and extreme parasympathetic activity.
Question 2 of 5
When the ventricles relax
Correct Answer: A
Rationale: Ventricular relaxation (diastole) causes a drop in pressure, allowing blood to fill the ventricles from the atria, not forcing valves open or reversing flow.
Question 3 of 5
Which information should the nurse include when teaching a patient with newly diagnosed hypertension?
Correct Answer: D
Rationale: Hypertension is usually asymptomatic until target organ damage has occurred. Lifestyle changes(e.g., physical activity, dietary changes) are used to help manage blood pressure, but drugs are needed for most patients. Home BP monitoring should be taught to the patient and findings checked by the health care provider frequently when starting treatment for hypertension and then every 3 months once stable.
Question 4 of 5
A nurse is teaching an adult female patient about the risk factors for hypertension. What should the nurse explain as risk factors for primary hypertension?
Correct Answer: A
Rationale: Obesity, stress, high intake of sodium or saturated fat, and family history are all risk factors for primary hypertension. Diabetes and oral contraceptives are risk factors for secondary hypertension. Metabolic syndrome, renal disease, and coarctation of the aorta are causes of secondary hypertension.
Question 5 of 5
A newly diagnosed patient with hypertension is prescribed Diuril, a thiazide diuretic. What patient education should the nurse provide to this patient?
Correct Answer: C
Rationale: Thiazide diuretics can cause postural hypotension, which may be potentiated by alcohol, barbiturates, opioids, or hot weather. Diuril does not cause either moderate hyperkalemia or severe hypokalemia and it does not result in hypernatremia.
