QUESTION 1
To appropriately monitor therapy and client progress, the nurse should be aware that increased myocardial
work and O2 demand will occur with which of the following?
A. Positive inotropic therapy
B. Negative chronotropic therapy
C. Increase in balance of myocardial O2 supply and demand
D. Afterload reduction therapy
Correct Answer: A
Section: Questions Set A
Explanation
Explanation/Reference:
Explanation:
(A) Inotropic therapy will increase contractility, which will increase myocardial O2 demand. (B) Decreased
heart rate to the point of bradycardia will increase coronary artery filling time. This should be used
cautiously because tachycardia may be a compensatory mechanism to increase cardiac output. (C) The
goal in the care of the MI client with angina is to maintain a balance between myocardial O2 supply and
demand. (D) Decrease in systemic vascular resistance by drug therapy, such as IV nitroglycerin or
nitroprusside, or intra-aortic balloon pump therapy, would decrease myocardial work and O2 demand.
QUESTION 2
The nurse would need to monitor the serum glucose levels of a client receiving which of the following
medications, owing to its effects on glycogenolysis and insulin release?
A. Norepinephrine (Levophed)
B. Dobutamine (Dobutrex)
C. Propranolol (Inderal)
D. Epinephrine (Adrenalin)
Correct Answer: D
Section: Questions Set A
Explanation
Explanation/Reference:
Explanation:
(A) Norepinephrine’s side effects are primarily related to safe, effective care environment and include
decreased peripheral perfusion and bradycardia. (B) Dobutamine’s side effects include increased heart
rate and blood pressure, ventricular ectopy, nausea, and headache. (C) Propranolol’s side effects include
elevated blood urea nitrogen, serum transaminase, alkaline phosphatase, and lactic dehydrogenase. (D)
Epinephrine increases serum glucose levels by increasing glycogenolysis and inhibiting insulin release.
Prolonged use can elevate serum lactate levels, leading to metabolic acidosis, increased urinary
catecholamines, false elevation of blood urea nitrogen, and decreased coagulation time.
QUESTION 3
Which of the following medications requires close observation for bronchospasm in the client with chronic
obstructive pulmonary disease or asthma?
A. Verapamil (Isoptin)
B. Amrinone (Inocor)
C. Epinephrine (Adrenalin)
D. Propranolol (Inderal)
Correct Answer: D
,Section: Questions Set A
Explanation
Explanation/Reference:
Explanation:
(A) Verapamil has the respiratory side effect of nasal or chest congestion, dyspnea, shortness of breath
(SOB), and wheezing. (B) Amrinone has the effect of increased contractility and dilation of the vascular
smooth muscle. It has no noted respiratory side effects. (C) Epinephrine has the effect of bronchodilation
through β stimulation. (D) Propranolol, esmolol, and labetalol are all β- blocking agents, which can increase
airway resistance and cause bronchospasms.
QUESTION 4
The following medications were noted on review of the client’s home medication profile. Which of the
medications would most likely potentiate or elevate serum digoxin levels?
A. KCl
B. Thyroid agents
C. Quinidine
D. Theophylline
Correct Answer: C
Section: Questions Set A
Explanation
Explanation/Reference:
Explanation:
(A) Hypokalemia can cause digoxin toxicity. Administration of KCl would prevent this. (B) Thyroid
agents decrease digoxin levels. (C) Quinidine increases digoxin levels dramatically. (D) Theophylline is
not notedto have an effect on digoxin levels.
QUESTION 5
In the client with a diagnosis of coronary artery disease, the nurse would anticipate the complication of
bradycardia with occlusion of which coronary artery?
A. Right coronary artery
B. Left main coronary artery
C. Circumflex coronary artery
D. Left anterior descending coronary artery
Correct Answer: A
Section: Questions Set A
Explanation
Explanation/Reference:
Explanation:
(A) Sinus bradycardia and atrioventricular (AV) heart block are usually a result of right coronary artery
occlusion. The right coronary artery perfuses the sinoatrial and AV nodes in mostindividuals. (B)
Occlusionof the left main coronary artery causes bundle branch blocks and premature ventricular
contractions. (C) Occlusion of the circumflex artery does not cause bradycardia. (D) Sinus tachycardia
occurs primarily with left anterior descending coronary artery occlusion because this form of occlusion
impairs left ventricular function.
QUESTION 6
When inspecting a cardiovascular client, the nurse notes that he needs to sit upright to breathe. This
behavior is most indicative of:
, A. Pericarditis
B. Anxiety
C. Congestive heart failure
D. Angina
Correct Answer: C
Section: Questions Set A
Explanation
Explanation/Reference:
Explanation:
(A) Pericarditis can cause dyspnea but primarily causes chest pain. (B) Anxiety can cause dyspnea
resulting in SOB, yet it is not typically influenced by degree of head elevation. (C) The inability to
oxygenatewell without being upright is most indicative of congestive heart failure, due to alveolar
drowning. (D) Angina causes primarily chest pain; any SOB associated with angina is not influenced by
body position.
QUESTION 7
When a client questions the nurse as to the purpose of exercise electrocardiography (ECG) in thediagnosis
of cardiovascular disorders, the nurse’s response should be based on the fact that:
A. The test provides a baseline for further tests
B. The procedure simulates usual daily activity and myocardial performance
C. The client can be monitored while cardiac conditioning and heart toning are done
D. Ischemia can be diagnosed because exercise increasesO2 consumption and demand
Correct Answer: D
Section: Questions Set A
Explanation
Explanation/Reference:
Explanation:
(A) The purpose of the study is not to provide a baseline for further tests. (B) The test causes an increase in
O2 demand beyond that required to perform usual daily activities. (C) Monitoring does occur, but the test
is not for the purpose of cardiac toning and conditioning. (D) Exercise ECG, or stress testing, is designed to
elevate the peripheral and myocardial needs for O2 to evaluate the ability of the myocardium and
coronaryarteries to meet the additional demands.
QUESTION 8
In assessing cardiovascular clients with progression of aortic stenosis, the nurse should be aware thatthere
is typically:
A. Decreased pulmonary blood flow and cyanosis
B. Increased pressure in the pulmonary veins and pulmonary edema
C. Systemic venous engorgement
D. Increased left ventricular systolic pressures and hypertrophy
Correct Answer: D
Section: Questions Set A
Explanation
Explanation/Reference:
Explanation:
(A) These signs are seen in pulmonic stenosis or in response to pulmonary congestion and edema and
mitral stenosis. (B) These signs are seen primarily in mitral stenosis or as a late sign in aortic stenosis afterleft
