Question 1:
What is the primary purpose of telemetry monitoring in a medical-surgical unit?
A) To administer medications remotely
B) To provide continuous electrocardiographic monitoring
C) To perform laboratory tests automatically
D) To conduct patient interviews
Correct Answer: B) To provide continuous electrocardiographic monitoring
Rationale: Telemetry monitoring allows for the continuous observation of a patient's
heart rhythm, helping healthcare professionals detect abnormal heart rates and rhythms
in real time. This proactive monitoring can lead to quicker interventions, thereby
improving patient outcomes. While medication administration and lab tests are integral
parts of patient care, they are not the primary focus of telemetry.
Question 2:
Which electrolytes should be monitored closely in a patient on digoxin therapy?
A) Sodium and potassium
B) Calcium and magnesium
C) Potassium and magnesium
D) Sodium and calcium
Correct Answer: C) Potassium and magnesium
Rationale: Proper monitoring of potassium and magnesium levels is critical in patients
receiving digoxin, as both electrolytes play a significant role in cardiac function.
Hypokalemia (low potassium) can increase the risk of digoxin toxicity, while low

magnesium levels can lead to cardiac arrhythmias. Regular checks help ensure that
these electrolytes remain within the therapeutic range.
Question 3:
What intervention is paramount for a patient experiencing chest pain before arriving at
the hospital?
A) Assessing vital signs
B) Providing nitroglycerin
C) Administering aspirin
D) Performing CPR
Correct Answer: C) Administering aspirin
Rationale: Administering aspirin is a critical intervention for a patient experiencing
chest pain, as it helps inhibit platelet aggregation and reduces the risk of further clot
formation in the event of a myocardial infarction. While assessing vital signs and
providing nitroglycerin may be appropriate actions, they do not have the same life-
saving potential as early aspirin use. CPR is only indicated if the patient is unresponsive
and not breathing.
Question 4:
In patients with heart failure, why is monitoring daily weights essential?
A) To assess dietary intake
B) To evaluate fluid retention
C) To monitor heart rate changes
D) To administer medications
Correct Answer: B) To evaluate fluid retention
Rationale: Daily weights are crucial in patients with heart failure because they offer an
early indication of fluid retention. A sudden increase in weight may signal worsening
heart failure and fluid overload, prompting timely medical intervention. Weight
monitoring is a straightforward and effective method for assessing changes in fluid status
and can guide treatment decisions.

Question 5:
What is the most appropriate nursing intervention for a patient experiencing a rapid
atrial fibrillation episode?
A) Encourage deep breathing exercises
B) Administer prescribed antiarrhythmic medications
C) Obtain a baseline ECG
D) Prepare for immediate cardioversion
Correct Answer: B) Administer prescribed antiarrhythmic medications
Rationale: In a patient experiencing rapid atrial fibrillation, the priority is to administer
prescribed antiarrhythmic medications, as these can help control the heart rate and
rhythm. While obtaining an ECG and preparing for cardioversion may be relevant later,
they do not address the immediate need to stabilize the patient's condition. Deep
breathing exercises, while beneficial for anxiety reduction, are not a primary
intervention for managing atrial fibrillation.
Question 6:
Which symptom is most commonly associated with left-sided heart failure?
A) Jugular vein distention
B) Peripheral edema
C) Shortness of breath
D) Abdominal ascites
Correct Answer: C) Shortness of breath
Rationale: Left-sided heart failure often leads to pulmonary congestion, resulting in
symptoms such as shortness of breath and orthopnea. While jugular vein distention and
peripheral edema are more associated with right-sided heart failure, shortness of breath
is a classic symptom arising from fluid accumulation in the lungs.
