A patient's heart rate increased from 94 to 164 beats/min. What will the nurse expect as a result?

Decrease in hemoglobin level

Increase in diastolic filling time

Increase in stroke volume

Decrease in cardiac output

Answer and Explanation

The Correct Answer is D

A. An increase in heart rate does not directly affect hemoglobin levels; this option is incorrect.
B. A higher heart rate decreases diastolic filling time, as there is less time for the heart to fill between beats, which can lead to reduced stroke volume.
C. An increased heart rate does not inherently increase stroke volume; in fact, at very high rates, stroke volume can decrease due to reduced filling time.
D. The significant increase in heart rate to 164 beats/min can lead to decreased cardiac output due to compromised diastolic filling and reduced stroke volume.

Correct Answer is D

Explanation

A. The nursing diagnosis "Impaired physical mobility" is appropriate and does not need revision.
B. There is no collaborative problem mentioned in the statement that requires revision.
C. The defining characteristic "patient's inability to ambulate" accurately reflects the patient's current condition and does not need changes.
D. The etiology "related to tibial fracture" should be revised to reflect a more precise causal factor that can be addressed by nursing interventions. A more appropriate etiology could specify the limitation in mobility rather than just stating the fracture.

A. Certification B. Licensure C. Autonomy D. Accountability

Correct Answer is C

Explanation

A. Certification relates to additional qualifications and does not directly involve independent nursing actions in patient care.
B. Licensure is the legal permission to practice nursing but does not describe decision-making and action in patient care.
C. Autonomy is demonstrated when the nurse independently assesses the patient’s fluid status and takes action to promote health by encouraging fluid intake. This reflects the nurse’s ability to make decisions and act based on professional judgment.
D. Accountability refers to being responsible for one's actions but does not specifically cover the independent decision-making shown here.
