A 34-year-old man is a chronic alcoholic and is in and out of a rehabilitation center on a monthly basis. His physician administers a blocker of aldehyde dehydrogenase. Which of the following effects is most likely to be exhibited by this patient following administration?
- A. Bradycardia
- B. Elation
- C. Euphoria
- D. Nausea
Correct Answer: D
Rationale: Disulfiram, an aldehyde dehydrogenase blocker, is used in alcoholism to deter drinking. When alcohol is consumed, acetaldehyde accumulates, causing nausea . Bradycardia isn't typical; tachycardia may occur with acetaldehyde buildup. Elation and euphoria contradict the aversive intent. Urticaria (E) is possible but less common. Nausea, with flushing and vomiting, creates an unpleasant reaction, reinforcing abstinence. This aligns with disulfiram's mechanism, leveraging acetaldehyde toxicity to modify behavior, distinguishing it from other effects.

Samuel, a 65-year-old patient comes into the hospital for an anginal attack. Which of the following is an important nursing intervention when administering Nitroglycerine?
- A. If the patient has more pain, apply another transdermal patch and keep the others on
- B. Don't wash the skin after removing a transdermal patch
- C. Remove the transdermal patch 10-12 hours every night to prevent tolerance
- D. Monitor blood pressure only after administration
Correct Answer: C
Rationale: The correct nursing intervention when administering Nitroglycerine to a patient like Samuel is to remove the transdermal patch 10-12 hours every night to prevent tolerance. Tolerance can develop rapidly with Nitroglycerine, leading to decreased effectiveness in managing anginal attacks. By removing the patch at night, the body has a chance to "reset" and reduce the likelihood of tolerance development. This practice helps maintain the drug's effectiveness and ensures better symptom control for the patient.
