29
Q

Actions of Leukotriene Receptor antagonists

A

Selectively and competitively block or antagonize receptors for the production of leukotrienes.

30

A

Prophylacis and chronic treatment of bronchial asthma in adults and in patients younger than 12 years of age.

31
Q

pharmacokinetics or Leukotriene Receptor Antagonists

A

Rapidly absorbed from the GI tract, extensively metabolized in the liver and primarily excreted in feces.

32
Q

Cation and Adverse effects of Leukotriene Receptor antagonists

A

hepatic or renal impairment. pregnancy and action.

Contraindications and Adverse effects of Lung surfactants.

A

Emergency drugs there are no contraindications.
Patent ductus arteriosus, hypotension, intraventriuclar hemorrhage, pneumothorax, pulmonary air leak, hyperbilrubinemia, sepsis.

37
Q
Which of the following is a contraindication to using lung surfactants. 
A) prematurity 
B) Older Adult
C) None
D) COPD
A

C) no contraindications as it is an emergency drug.

38
Q

The nurse is caring for a patient taking Budesonide. wHat would be an appropriate nursing diagnosis for this patient?
A) Risk for injury related to immunosuppression.
B) Risk for injury related to CNS effects
C) Risk for injury related to CVS effects
D) Risk for injury related to age and risk of infection

A

A)Risk for injury related to immunosuppression.
Rationale: Nursing diagnoses related to drug therapy might include: risk for injury related to immunosuppression; acute pain related to local effects of the drug; deficient knowledge regarding drug therapy.

True or flase

A

TRUE
Rationale: Adverse Effects: Related to theophylline levels in the blood; GI upset, nausea, irritability, and tachycardia to seizure, brain damage, and even death.
