The nurse provides a client with a dose of the beta-selective adrenergic agonist isoproterenol. Which assessment finding indicates the medication is effective?
Constricted pupils
Warm, dry skin
Increased heart rate
Decreased urine output
The Correct Answer is C
A. Constricted pupils are not an expected response to isoproterenol, which generally causes dilation of the pupils due to sympathetic stimulation.
B. Warm, dry skin is not a direct indicator of the effectiveness of isoproterenol; it could result from various factors unrelated to the medication's action.
C. Increased heart rate indicates that isoproterenol, which is a beta-agonist, is effectively stimulating the beta-adrenergic receptors, leading to increased cardiac output and heart rate.
D. Decreased urine output is not a sign of effectiveness and could indicate adverse effects such as reduced renal perfusion.

Correct Answer is B
Explanation

B. Activated partial thromboplastin time (aPTT) is the primary laboratory test used to assess the effectiveness of heparin therapy, measuring the time it takes for blood to clot and ensuring therapeutic levels.
C. The International normalized ratio (INR) is also related to warfarin therapy rather than heparin.
D. Serum potassium level is not relevant for assessing heparin therapy but may be monitored for other reasons.
Correct Answer is ["A","B","D","E"]
Explanation
A. Maintain good oral hygiene to minimize dry mouth is correct; good oral hygiene practices can help alleviate dry mouth, which is a common anticholinergic effect.
B. Void before taking the medication so urinary hesitation is less problematic is correct; this strategy can help manage urinary retention, another potential side effect of tricyclic antidepressants.
C. Avoid situations where bruising or lacerations are a possibility is incorrect; while caution is always advisable, this statement does not directly relate to anticholinergic effects.
D. Eat several small meals daily rather than three larger meals is correct; smaller meals can help mitigate gastrointestinal side effects and maintain steady blood sugar levels.
E. Use caution in situations where it may be possible to become overheated is correct; anticholinergic medications can impair thermoregulation, increasing the risk of heat-related illnesses.
