A nurse is reviewing a client's cardiac rhythm strips and notes a constant P-R interval of
0.35 seconds. Which of the following dysrhythmias is the client displaying?

A. Constipation is a potential side effect of morphine, but it is not the priority concern in this scenario.
B. Euphoria is a potential side effect of morphine but is not as immediately concerning as bradypnea.
C. Correct. Bradypnea (slow breathing) is a potential adverse effect of morphine and can lead to respiratory depression, which is a serious concern.
D. Sedation is an expected side effect of morphine, but the priority concern is the possibility of respiratory depression.

Choice A rationale:

Headache is a common adverse effect of disulfiram when alcohol is consumed. It is part of the adverse reaction created by the drug to deter individuals from drinking. While headache is a known symptom, tinnitus is a more specific and distinctive adverse effect associated with disulfiram use.

Choice B rationale:

Hypertension is not a common adverse effect of disulfiram. Disulfiram does not directly impact blood pressure. Its primary action is to cause an adverse reaction when alcohol is consumed.

Choice C rationale:

Tinnitus (ringing in the ears) is a known adverse effect of disulfiram when alcohol is ingested. Disulfiram inhibits the breakdown of acetaldehyde, leading to an accumulation of this toxic substance in the body. Tinnitus is one of the symptoms of this toxic reaction and is a significant concern in individuals taking disulfiram for alcohol use disorder.

Choice D rationale:

Insomnia is not a common adverse effect of disulfiram. Disulfiram works by creating an unpleasant reaction when alcohol is consumed, which deters individuals from drinking. This reaction does not typically manifest as insomnia.
