A patient who takes a beta adrenergic blocker is at risk of developing shock after an accident. The nurse is aware that the patient's medication use may alter which assessment finding associated with shock?
1. Tachycardia
2. Declining mental status
3. Cyanosis
4. Tachypnea
1
Rationale 1: Beta adrenergic blockers inhibit the sympathetic nervous system, causing bradycardia. Because the patient is taking a beta blocker, the normal response of tachycardia may be blunted.
Rationale 2: The use of a beta blocker should not alter the neurological symptoms of shock.
Rationale 3: Cyanosis will still occur in a shock state, as beta blockers do not interfere with symptoms of poor oxygenation.
Rationale 4: Increase in respiratory rate is related to the body's need for more oxygenation. Beta blockers would not affect this finding.
