A patient asks the nurse what side effects to expect from a muscle relaxant medication that has been prescribed. Which of the ff. side effects should the nurse relate?
- A. Hypoglycaemia
- B. Drowsiness
- C. Hypotension
- D. Dyspnea
Correct Answer: B
Rationale: Muscle relaxant medications, such as benzodiazepines or cyclobenzaprine, commonly cause drowsiness as a side effect. This is a result of the medications affecting the central nervous system, leading to sedative effects. Patients taking muscle relaxants should be advised to avoid activities that require alertness, such as driving or operating machinery, until they understand how the medication affects them. It is important for the nurse to inform the patient about this potential side effect to ensure their safety and to prevent any accidents or injuries due to drowsiness. On the other hand, hypoglycemia, hypotension, and dyspnea are not common side effects of muscle relaxant medications.
