Answer to Question 1
2, 3, 5
Rationale 1:Blood pressure is not a primary characteristic of heart function.
Rationale 2:Speed of impulse conduction is one of the primary characteristics.
Rationale 3:Contractility or force of contraction is a primary characteristic of heart function.
Rationale 4:Respirations are not associated with heart function.
Rationale 5: Heart rate is a primary characteristic of heart function.
Global Rationale: Three fundamental characteristics of heart function are force of contraction or contractility, heart rate, and speed of impulse conduction.
Answer to Question 2
2
Rationale 1: Cardiac glycosides are held if the pulse is less than 60 bpm.
Rationale 2: If the rate is lower than 60 beats per minute, the drug should not be given.
Rationale 3: Cardiac glycosides do not have an effect on temperature.
Rationale 4: Cardiac glycosides are held if the pulse is less than 60 bpm.
Global Rationale: If the rate is lower than 60 beats per minute, the drug should not be given. Blood pressure of 119/66, a temperature of 99.4F, and respirations of 12 breaths per minutes would not cause the nurse to hold the dose of medication.
