Tested Questions & Verified Answers | Latest Update |
Graded A+
1. What class of drugs is characterized by the suffix '-sartan'?
Angiotensin II receptor blockers (ARBs)
Calcium channel blockers
ACE inhibitors
Beta-blockers
2. Describe the primary action of cephalosporins in the treatment of infections.
Cephalosporins enhance protein synthesis in bacteria.
Cephalosporins neutralize bacterial toxins.
Cephalosporins work by inhibiting bacterial cell wall synthesis.
Cephalosporins disrupt DNA replication in bacteria.
3. Drugs usually ending in -sone are associated with
Antilipemic
ACE Inhibitor
Steroids
Antivirals
4. Describe the primary action of benzodiazepines in the body.
Benzodiazepines increase heart rate and blood pressure.
Benzodiazepines block the reuptake of dopamine.
, Benzodiazepines act as central nervous system depressants,
enhancing the effect of the neurotransmitter GABA.
Benzodiazepines stimulate the release of serotonin in the brain.
5. What drug class does acetylsalicylic acid (ASA) belong to?
Anticoagulants
Antiplatelet agents
Antibiotics
ACE inhibitors
6. Describe the significance of timing when administering Loop Diuretics.
Timing is irrelevant as Loop Diuretics work the same regardless of
when they are given.
Administering Loop Diuretics in the morning helps prevent nocturia
and promotes effective fluid management.
Administering Loop Diuretics at night is preferred to avoid daytime
side effects.
Loop Diuretics should be given at any time to ensure maximum
absorption.
7. The nurse giving Acetaminophen understands this medication belongs to
what drug class?
non-opioid analgesic
benzodiazepine
opioid analgesic
NSAID
,8. A patient is prescribed acetylsalicylic acid (ASA) after a myocardial infarction.
What is a critical nursing responsibility when administering this medication?
Evaluate renal function.
Monitor for signs of bleeding.
Check blood glucose levels.
Assess for respiratory distress.
9. Describe how Phenothiazine medications affect the central nervous system
and the implications for patient care.
Phenothiazine medications can cause sedation and other central
nervous system effects, requiring careful monitoring of patients'
alertness and safety.
Phenothiazine medications are only used for treating infections.
Phenothiazine medications have no significant effects on the central
nervous system.
Phenothiazine medications primarily affect the cardiovascular system,
leading to increased heart rate.
10. When should loop diuretics such as Furosemide be administered for
maximum effectiveness?
In the afternoon
In the middle of the night
In the evening
Early in the morning
, 11. Describe the importance of monitoring heart rate before giving digoxin to a
patient.
Monitoring heart rate is only important for patients with a history of
heart disease.
Monitoring heart rate helps determine the patient's blood pressure
response to digoxin.
Monitoring heart rate is unnecessary as digoxin does not affect heart
rhythm.
Monitoring heart rate is crucial because digoxin can cause
bradycardia, and administering it when the heart rate is too low can
lead to serious complications.
12. Describe the primary action of tetracyclines in the treatment of infections.
Tetracyclines disrupt cell wall synthesis.
Tetracyclines neutralize toxins.
Tetracyclines inhibit bacterial protein synthesis.
Tetracyclines enhance immune response.
13. A patient is prescribed a medication that ends with the suffix '-parin'. What
nursing responsibility is crucial for monitoring this patient?
Monitor blood glucose levels.
Monitor heart rate and rhythm.
Monitor for signs of infection.
Monitor for signs of bleeding.
