The Concept of Perfusion (Pearson)What will the nurse most likely assess in a client with right heart failure?
A) Leg cramps
B) Indigestion
C) Reduced circulation to the pulmonary structures
D) Reduced urine output - answer: C
Explanation: C) Circulation to the pulmonary structures begins with the right side of the
heart. The client with right heart failure will have reduced circulation to these structures.
There is no evidence to suggest that right heart failure will cause indigestion or reduced
urine output. Not all clients with right heart failure experience leg cramps.
The nurse is concerned that a client with an alteration in perfusion is at risk for
inadequate oxygenation. What should the nurse consider when planning for this client's
potential health problem?
A) Cluster activities.
B) Instruct on deep breathing.
C) Medications appropriate to increase heart rate
D) Positioning to increase blood return - answerAnswer: B
Explanation: B) The client is at risk for inadequate oxygenation. The nurse should
consider teaching the client the importance of deep breathing to increase the amount of
oxygen in the body tissues. Clustering activities would negatively impact oxygenation.
Periods of rest should occur between activities. The client with oxygenation issues will
have tachycardia. The nurse should consider medications that would reduce instead of
increase the heart rate. The client should be in the high-Fowler position to improve
oxygenation. Positions to increase blood flow to the heart would include Trendelenburg,
which would negatively impact oxygenation.
An older client is diagnosed with cardiomyopathy and a cardiac dysrhythmia. What
would the nurse expect to be indicated for this client?
A) Beta blocker
B) Digoxin
C) Nitrate medications
D) Fluids - answerAnswer: A
Explanation: A) Treatment for cardiomyopathy includes calcium channel blockers, beta
blockers, and antiarrhythmics. Nitrates should be avoided because they increase blood
pressure. Digoxin should be avoided because it increases the force of contractions. The
client should be on a sodium and fluid restriction and not be encouraged to drink fluids.
