Sudden muscular contractions
Orthostatic hypotension
Anticholinergic effects
Tremors
Sedation
Increased urination
Correct Answer : A,B,C,D,E
Rationale:
A. Sudden muscular contractions: Antipsychotics like haloperidol and chlorpromazine can cause extrapyramidal symptoms (EPS), including acute dystonia, which manifests as sudden, involuntary muscle contractions typically affecting the face, neck, or back.
B. Orthostatic hypotension: Chlorpromazine, a low-potency typical antipsychotic, often causes orthostatic hypotension due to its alpha-adrenergic blockade, increasing fall risk, especially in older adults or those new to therapy.
C. Anticholinergic effects: These include dry mouth, blurred vision, constipation, and urinary retention. Chlorpromazine is particularly known for its anticholinergic side effects due to its action on muscarinic receptors.
D. Tremors: Tremors are part of parkinsonian side effects, another form of EPS commonly caused by haloperidol. They result from dopamine blockade in the nigrostriatal pathway.
E. Sedation: Both haloperidol and chlorpromazine can cause sedation. Chlorpromazine is especially sedating due to its histamine (H1) receptor blockade, which depresses the CNS.
F. Increased urination: Not typically associated with these medications. In fact, anticholinergic effects from chlorpromazine more often lead to urinary retention, not increased urination.

Correct Answer is A
Explanation
Rationale:
A. “You can obtain a personal response system that will be activated if you fall.": Personal emergency response systems (PERS) allow individuals who live alone to call for help immediately in case of a fall or emergency.
B. “You need to move to a skilled nursing facility where they can prevent falls.": Moving to a skilled nursing facility is a major step and is not necessary solely due to fear of falling. It may also provoke anxiety or feelings of loss of autonomy, especially if less invasive alternatives are available.
C. "You can have an unlicensed assistive personnel (UAP) come to your house daily to stay with you.": Daily UAP support may not be realistic or necessary for someone who is still generally independent. This level of care may be excessive unless the client has significant mobility or cognitive impairments.
D. "You should contact a family member once a week to keep in touch.": While weekly contact with family can offer emotional support, it does not provide real-time assistance in the event of a fall. It’s not a sufficient solution for immediate safety concerns.
Correct Answer is ["A","B","C","D","E","F"]
Explanation
Rationale:
A. Blood pressure: Orthostatic hypotension is evident from the drop in systolic and diastolic pressure when standing, indicating fluid and electrolyte imbalance. This may reflect volume depletion due to purging and requires monitoring to prevent fainting or falls.
B. Syncope: The client reports repeated fainting episodes, a red flag when paired with orthostatic hypotension and electrolyte disturbances. This suggests unstable cardiovascular status and raises the risk of injury or sudden cardiac events.
C. ECG: Sinus tachycardia with premature ventricular contractions indicates cardiac irritability likely due to electrolyte imbalance, especially hypokalemia. Continuous cardiac monitoring and correction of abnormalities are needed.
D. Albumin: An albumin level of 2.6 g/dL indicates significant malnutrition and protein deficiency, compromising immune function and wound healing. This also suggests a chronic issue requiring dietetic intervention and nutritional rehabilitation.
E. Potassium: Potassium at 3.0 mEq/L is dangerously low and a known contributor to cardiac arrhythmias and muscle weakness. Replenishment and close monitoring are critical to avoid complications such as cardiac arrest.
F. Sodium: Although sodium is only slightly low at 134 mEq/L, in the context of purging and poor intake, this could indicate dilutional hyponatremia. It increases seizure risk and needs assessment of fluid status and intake behaviors.
