A client on heparin has a platelet count that falls by more than half. What should the nurse suspect?

Which laboratory test is used to monitor IV unfractionated heparin therapy?

A client on long-term amiodarone develops a new dry cough and dyspnea. Which adverse effect should the nurse suspect?

What should the nurse anticipate immediately after giving adenosine for supraventricular tachycardia?
सही उत्तर: क) A brief period of asystole or very slow rhythm
Adenosine transiently blocks AV-node conduction and may cause a few seconds of asystole. Its half-life is under 10 seconds, so it is given by rapid IV push with a flush.

-
Which drug should be used with caution in a client with asthma because it may cause bronchospasm?

-
Which drug class must not be taken with nitrates because of severe hypotension?
सही उत्तर: घ) Phosphodiesterase-5 inhibitors (e.g. sildenafil)
PDE-5 inhibitors and nitrates both increase nitric oxide-mediated vasodilation, causing profound hypotension. Beta-blockers are often co-prescribed with nitrates.
