Hypothermia
The dysrhythmia itself is not treated, but the cause is identified and treated
appropriately. Causes of sinus tachycardia include hypovolemia, heart failure,
anemia, exercise, use of stimulants, fever, sympathetic response to fear or
pain. Hypothermia will cause sinus bradycardia.
Test-Taking Tip: Do not read too much into the question or worry that it is a
"trick." If you have nursing experience, ask yourself how a classmate who is
inexperienced would answer this question from only the information provided
in the textbooks or given in the lectures.

A client with a history of heart failure and hypertension is admitted
with reports of syncope. Which prescribed medication should the nurse
prepare to administer based on the electrocardiogram (ECG) rhythm
strip image?
,1
Digoxin
2
Enalapril
Correct3
Atropine
4
Metoprolol
This rhythm strip reflects sinus bradycardia. Sinus bradycardia has PQRST
complexes within acceptable limits, but the rate is less than 60 beats per
minute. In this strip the PR interval is 0.16, the rhythm is regular, and the
rate is 40 beats per minute. Atropine, an anticholinergic that increases the
heart rate, is administered when the heart rate is so slow that it causes
symptoms. Digoxin is a cardiac glycoside that slows the heart rate. Enalapril
is an angiotensin-converting enzyme (ACE) inhibitor that slows the heart
rate. Metoprolol is a beta blocker that slows the heart rate.

A client is in the intensive care unit. The nurse observing the telemetry
monitor identifies flattening T waves and peaked P waves. What
problem should the nurse consider based on these ECG changes?
Correct1
Hypokalemia
2
Hypocalcemia
3
Hyponatremia
4
Hypomagnesemia
Flattened or inverted T waves, peaked P waves, depressed ST segments, and
elevated U waves are associated with hypokalemia. Prolongation of the QT
interval may indicate hypocalcemia. Hyponatremia is not reflected in the
heart’s electrical conduction. Although flattening of T waves may occur with
hypomagnesemia, the ST segment may be shortened, and the PR and QRS
intervals may be prolonged.

To which assessment findings should the nurse give the highest priority
when caring for a client with symptomatic sinus tachycardia? Select
all that apply.
1
Anxiety
Correct2
Orthopnea
3
Restlessness
Correct4
Lightheadedness
Correct5
Decreased blood pressure
The assessment findings having the highest priority for clients with
symptomatic sinus tachycardia are orthopnea (shortness of breath while
lying flat), lightheadedness, and decreased blood pressure because these
assessments can help to quickly identify the client’s condition and the most
effective treatment for it. Anxiety and restlessness are frequently observed
, in a client with symptomatic sinus tachycardia, but they are not the nurse’s
highest priority.
