Answer to Question 1

A, C, D
Feedback:
Stimulation of muscarinic receptors causes pupil constriction, increased gastrointestinal (GI) motility and secretions (including saliva), increased urinary bladder contraction, and a slowing of the heart rate. Pupils are constricted, not dilated and heart rate slows, it does not increase.

Answer to Question 2

B
Feedback:
Because dehydration is an adverse effect of aprepitant, the nurse will want to encourage the patient to drink as much liquid as possible. Elevating the head of the bed would be unnecessary; the patient's temperature would not be affected by aprepitant; we are encouraging fluids so placing an NPO sign on the door would not be appropriate for this patient.
