A client admitted for uncontrolled hypertension and chest pain was started
on a daily diuretic two days ago upon admission, with prescriptions for a
daily basic metabolic panel. The clients potassium level this morning is 2.7
mEq/L. Which action should the nurse take next?
A. Notify the healthcare provider that the potassium level is above normal
B. Notify the healthcare provider that the potassium level is below normal
,C. No action is required because the potassium level is within normal
limits
D. Hold the clients morning diuretic dose - ANSWER-B
Which of the following actions is the first priority of care for a client
exhibiting signs and symptoms of coronary artery disease?
A) Decrease anxiety
B) Enhance myocardial oxygenation
C) Administer sublingual nitroglycerin
D) Educate the client about his symptoms - ANSWER-B
Enhancing myocardial oxygenation is always the first priority when a client
exhibits signs or symptoms of cardiac compromise. Without adequate
oxygenation, the myocardium suffers damage. Sublingual nitroglycerin is
administered to treat acute angina, but administration isn't the first priority.
Although educating the client and decreasing anxiety are important in care
delivery, neither are priorities when a client is compromised.
Medical treatment of coronary artery disease includes which of the
following procedures?
,A) Cardiac catherization
B) Coronary artery bypass surgery
C) Oral medication therapy
D) Percutaneous transluminal coronary angioplasty -
ANSWER-C
Enhancing myocardial oxygenation is always the first priority when a client
exhibits signs or symptoms of cardiac compromise. Without adequate
oxygenation, the myocardium suffers damage. Sublingual nitroglycerin is
administered to treat acute angina, but administration isn't the first priority.
Although educating the client and decreasing anxiety are important in care
delivery, neither are priorities when a client is compromised.3. Oral
medication administration is a noninvasive, medical treatment for coronary
artery disease. Cardiac catherization isn't a treatment, but a diagnostic tool.
Coronary artery bypass surgery and percutaneous transluminal coronary
angioplasty are invasive, surgical treatments.
Which of the following is the most common symptom of myocardial
infarction (MI)?
A) Chest pain
B) Dyspnea
C) Edema
, D) Palpitations - ANSWER-A
Which of the following blood tests is most indicative of cardiac damage?
A) Lactate dehydrogenase
B) Complete blood count (CBC)
C) Troponin I
D) Creatine kinase (CK) - ANSWER-C
Troponin I levels rise rapidly and are detectable within 1 hour of myocardial
injury. Troponin I levels aren't detectable in people without cardiac injury.
Lactate dehydrogenase (LDH) is present in almost all body tissues and not
specific to heart muscle. LDH isoenzymes are useful in diagnosing cardiac
injury. CBC is obtained to review blood counts, and a complete chemistry is
obtained to review electrolytes. Because CK levels may rise with skeletal
muscle injury, CK isoenzymes are required to detect cardiac injury.
What is the primary reason for administering morphine to a client with an
MI?
A) To sedate the client
B) To decrease the client's pain
