(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. Fine hand tremors and pill rolling: These symptoms are more indicative of parkinsonism, which is another extrapyramidal side effect of antipsychotic medications but not specifically tardive dyskinesia.
B. Facial grimacing and eye blinking: Facial grimacing and eye blinking are classic signs of tardive dyskinesia. These involuntary movements of the face are often seen in patients who have been on antipsychotic medications for an extended period.
C. Urinary retention and constipation: Urinary retention and constipation are not typically associated with tardive dyskinesia. These symptoms may be related to other medication side effects or unrelated conditions.
D. Involuntary pelvic rocking and hip thrusting movements: These movements are characteristic of tardive dyskinesia. Involuntary pelvic rocking and hip thrusting can occur as part of the abnormal involuntary movements seen in tardive dyskinesia.
E. Tongue thrusting and lip smacking: Tongue thrusting and lip smacking are classic signs of tardive dyskinesia, particularly involving the orofacial region. These movements can be distressing for patients and may interfere with speech and eating.

A. "I will be sure to take the albuterol before taking the cromolyn": Taking albuterol before cromolyn is the correct sequence because albuterol is a bronchodilator that helps open the airways quickly, while cromolyn is a mast cell stabilizer that helps prevent asthma symptoms. Taking albuterol first allows for better penetration of cromolyn into the airways. Therefore, this statement indicates an understanding of the appropriate sequence for using the medications.
B. "I will use both medications immediately after exercising": While it is essential to use albuterol before exercise to prevent exercise-induced bronchospasm, using cromolyn immediately after exercise is not typically indicated. Cromolyn is more effective when used prophylactically to prevent asthma attacks triggered by allergens or exercise rather than as an acute rescue medication.
C. "If my breathing begins to feel tight, I will use the cromolyn immediately": Cromolyn is not indicated for the immediate relief of acute bronchospasm. It works best when used regularly to prevent asthma symptoms rather than as a rescue medication during an asthma attack. Albuterol is the appropriate choice for immediate relief of tightness or wheezing.
D. "I will administer the medications 10 minutes apart": While it's important to space out the administration of different medications to ensure proper absorption and effectiveness, the specific timing between albuterol and cromolyn may vary based on individual instructions from the healthcare provider. Generally, it's recommended to take albuterol first, followed by cromolyn after a brief interval.
