Chest pain
SOB
GI distress
Flushing
Dizziness,
Tachycardia
Arrhythmias
Myocardial ischemia or MI

33
Q

Mechanism of action of beta blockers?

A

Blocks the effects of adrenaline (epinephrine) and noradrenaline (norepinephrine) on the heart to slow heart rate.

34
Q

Mechanism of action of statins?

A

Reduces the amount of cholesterol produced in the liver and reduces narrowing of arteries.

35
Q

Mechanism of action of fibrinolytic drugs?

A

Convert plasminogen to the enzyme plasmin to break down clots.

36
Q

Examples of a fibrinolytic drug?

A

Eminase
Retavase
Strepase

37
Q

Adverse reactions of fibrinolytics?

A

Bleeding
Dysrhythmias
Hypotension
Cholesterol embolism
PE

38
Q

What drugs shouldn’t be given with fibrinolytics?

A

Anticoagulants.

39
Q

Examples of anticoagulants?

A

Heparin
Coumadin
Plavix

40
Q

What is the antidote for heparin?

A

Protamine sulfate

41
Q

What education is important to provide when giving a patient plavix?

A

Foods contains vitamin K can reduce effectiveness of this medication.

42
Q

Mechanism of action of heparin?

A

Accelerating the rate of the neutralization of coagulation factors by antithrombin.

43
Q

Mechanism of action of Coumadin?

A

Inhibiting the production of vitamin K-dependent clotting factors.

44
Q

Mechanism of action of plavix?

A

Prevents blood platelets from clumping together.

45
Q

Broad Spectrum Antibiotics

A

A type of antibiotic that are effective against a wide range of bacteria, including both Gram-positive and Gram-negative bacteria.

46
Q

What is a tetracycline and penicillin drug interactions?

A

Contraceptives

47
Q

Secondary Fungal Infection

A

A fungal infection that can occur after another infection.

48
Q

Can children be given Pepto Bismol?

A

Never. Can cause Reye’s syndrome (Swelling in the liver).

49
Q

Benzodiazepines, opioids, muscle relaxants, hypnotics effect on the CNS?

A

Suppress the central nervous system. Alcohol and CNS depressants both act to suppress brain activity, including the areas that control breathing. When combined, their effects are amplified, increasing the risk of severe respiratory depression and lead to overdose and death.

Suicidal idealizations
Side effects are temporary
Take 4 to 6 weeks to work
No grapefruit
ED

51
Q

Must monitor electrolyte levels and renal function.

53

56
Q

Akathisia

A

Motor restlessness

Q

Medications for numbing with a UTI?

A

AZO
Phenazopyridine

58
Q

First pass effect

A

Partial metabolization in the hepatic system, drugs pass thru the liver up to 90% of drug is absorbed by the liver.

59
Q

What bodily system effects the eliminations of drugs?

A

Hepatic
Renal

60
Q

Idiosyncratic effect

A

An unusual or abnormal response to a substance or medication that is not normally seen in the general population.

61
Q

Additive effect

A

The combined effect of two or more drugs is equal to the sum of the effects of each drug acting individually

62
Q

Synergistic effect

A

The combined effect of two or more different drugs is greater than the sum of the effects of each drug acting individually.

63
Q

Drug reconciliation

A

The practice of comparing the patient’s drug orders to all of the drugs that the patient has been taking.

64
Q

Three-legged stool of evidence based practice

Q

What medications can not be given with glaucoma medications?

A

Beta 2 blockers

66
Q

Common treatment for otitis media?

A

Antibiotics

67
Q

Thrombocytopenia

A

Low platelets

68
Q

Platelet aggregation

A

Platelets adhere to one another to form clots and stop bleeding.

69
Q

SQ erthyropoietin monitoring?

A

Seizures
HTN
Hemoglobin
Thrombotic events

70
Q

Febrile Neutropenia

A

Febrile neutropenia is a condition that occurs when a person has a fever and a low level of neutrophils in their blood. Neutrophils are a type of white blood cell that help fight infection, so having too few of them increases the risk of infection. Common with those taking cancer drugs!
