1. Lewy Body Dementia
Question:
Which of the following best describes Lewy Body Dementia?
A. A memory disorder caused by vitamin deficiency
B. Abnormal protein deposits in the brain leading to fluctuating cognition, visual
hallucinations, and Parkinson-like motor symptoms
C. A genetic disorder affecting only children
D. Temporary confusion due to dehydration
Answer: B
Rationale:
1. Lewy bodies are abnormal protein deposits that accumulate in neurons.
2. These deposits cause fluctuating cognitive abilities, visual hallucinations, and
motor symptoms similar to Parkinson’s disease.
3. Unlike other dementias, Lewy Body Dementia often involves hallucinations and
Parkinsonian movements.
4. Early recognition is crucial for proper management and care planning.
2. Difference Between a Drug and a Medication
Question:
What is the primary difference between a drug and a medication?
,A. A drug is any substance that alters the body, while a medication is specifically used
to treat or prevent disease
B. A drug is always illegal, while medication is prescribed by doctors
C. Drugs are only stimulants, while medications are only sedatives
D. There is no difference; both are the same
Answer: A
Rationale:
1. A drug refers to any chemical substance, including narcotics, hallucinogens, or
stimulants.
2. Medication is a specific type of drug used to treat, manage, or prevent diseases.
3. Understanding this distinction is critical for safe administration and patient
education.
4. Proper labeling ensures that healthcare providers avoid misuse of drugs as
medications.
3. Components of a Doctor’s Order
Question:
Which of the following are essential components of a doctor's order for medication
administration?
A. Diagnosis, nurse name, and time of day
B. Medication, route, and frequency
C. Pharmacy, cost, and duration
D. Patient preference, age, and weight
Answer: B
Rationale:
1. Every doctor’s order must include the medication name to identify the drug.
2. The route specifies how the medication should be administered (e.g., oral, IV).
3. The frequency indicates how often the medication should be given.
4. Clear orders reduce errors and ensure patient safety during administration.
4. Parkinson’s Disease Symptoms
Question:
Which of the following is a common symptom of Parkinson’s disease?
,A. Fluctuating blood pressure
B. Tremors, rigidity, and bradykinesia
C. Visual hallucinations
D. Severe memory loss
Answer: B
Rationale:
1. Parkinson’s disease primarily affects motor function due to dopamine deficiency.
2. Common signs include tremors, muscle rigidity, and slowness of movement
(bradykinesia).
3. Non-motor symptoms may occur, but tremors and rigidity are most
characteristic.
4. Early recognition improves management with medications like levodopa.
5. Types of Memory Loss
Question:
Which type of memory loss is most commonly associated with Alzheimer’s disease?
A. Short-term memory loss
B. Long-term memory loss
C. Procedural memory loss
D. Sensory memory loss
Answer: A
Rationale:
1. Alzheimer’s disease typically affects short-term memory first.
2. Patients may forget recent events or conversations while retaining older
memories.
3. Gradual progression eventually impacts long-term and procedural memory.
4. Recognizing short-term memory deficits helps with early diagnosis.
6. Legal Responsibilities of Medication Administration
Question:
Which of the following is a legal responsibility of a healthcare provider when
administering medication?
, A. Guessing the dose if the order is unclear
B. Administering medication without verifying the patient
C. Following the “five rights” of medication administration
D. Ignoring expiration dates of medications
Answer: C
Rationale:
1. The “five rights” ensure safe administration: right patient, drug, dose, route, and
time.
2. Failure to follow these rights can lead to medication errors.
3. Legal accountability requires adherence to approved protocols.
4. Proper documentation further protects both the patient and healthcare provider.
7. Proper Hand Hygiene
Question:
Which is the most effective method to prevent the spread of infections in healthcare
settings?
A. Wearing gloves only
B. Hand hygiene using soap and water or alcohol-based sanitizer
C. Wearing a mask at all times
D. Using antiseptic spray on surfaces
Answer: B
Rationale:
1. Hand hygiene is the single most effective way to prevent healthcare-associated
infections.
2. Soap and water are essential when hands are visibly soiled; sanitizer works for
routine cleaning.
3. Gloves reduce contamination but do not replace hand washing.
4. Consistent practice reduces transmission of pathogens between patients and
staff.
8. Signs of Hypoglycemia
Question:
Which of the following is a common sign of hypoglycemia?
