'I will take the medication on an empty stomach.' B. 'I need to set an alarm so I take the medication on time.' C. 'It will be important to check my heart rate before taking the medication.' D. 'I should monitor for an increase in blood pressure after taking the medication.'

- A client with myasthenia gravis begins taking pyridostigmine. Two days later, the client develops loose stools and increased salivation. Which conclusion would the nurse make about these new developments?A. The client is experiencing a myasthenic crisis.B. The medication is causing cholinergic side effects.C. The medication is triggering a paradoxical reaction.D. The client is exhibiting toxic effects of the medication.

- Pyridostigmine is prescribed for a client with myasthenia gravis. Why would the nurse instruct the client to take pyridostigmine about 1 hour before meals? A. This timing limits first pass metabolism. B. Taking it on an empty stomach increases absorption. C. Taking it before meals decreases gastric irritation. D. Taking it before meals improves the ability to chew.

- Put the following structures in the order that blood passes through beginning with deoxygenated blood returning to the heart from the system.Right atrium Left Atrium Left AV valve Right AV valve Aortic Valve Pulmonary vein Pulmonary valves Left Ventricle Right Ventricle
- __________ carry blood to the heart and ____________ carry blood away from the heart.
- The amount of blood remaining in the left ventricle after the ejection phase is known as:
- Where did transmembrane channels in the axon terminal come from?-They were synthesized on bound ribosomes in the cell body and carried via slow axoplasmic transport - They were synthesized on bound ribosomes in the cell body and carried via fast axoplasmic transport -They were synthesized on bound ribosomes in the axon and carried via fast axoplasmic transport -They were synthesized on free ribosomes in the cell body and carried via slow axoplasmic transport
- Sensory afferents enter the spinal cord at the __________________ and motor efferents exit the spinal cord at the ___________________.
- All good primary sensory afferents leave their cell bodies outside the central nervous system in a dorsal root ganglion and do not cross the midline.
