  1. Blood pressure
  2. Speed of conduction
  3. Contractility of heart
  4. Respirations
  5. Heart rate

Question 2

The client is ordered to receive a cardiac glycoside. Which vital signs finding would make the nurse question administering this medication?
 
  1. Blood pressure 119/66
  2. Apical pulse 55 beats per minute
  3. Temperature 99.4F
  4. Respirations 12 breaths per minute

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.
