I passed my NCLEX in 85 Qs after 2 wks of study…
Which statement by the nurse regarding tricyclic antidepressants (TCAs) is correct?
1. "Increased saliva production is a common side effect."
2. "Insomnia is common in the first weeks of therapy."
3. "We will need to perform an ECG before you start this medication."
4. "It is an emergency if you notice dizziness when changing positions."

Rationale⬇️
Tricyclic antidepressants (TCAs) can cause cardiac dysrhythmias, so the nurse must obtain an ECG before the client starts this medication [Choice 3].
Incorrect:
[Choice 1]: TCAs have anticholinergic side effects, so clients will likely experience dry mouth rather than increased saliva production.
[Choice 2]: TCAs often cause sedation rather than insomnia.
[Choice 4]: Orthostatic hypotension is a common side effect that is not an emergency; clients should change positions slowly to prevent dizziness.

Tricyclic antidepressants (TCAs) are a class of medications commonly used to treat depression and certain other conditions, but they require careful monitoring due to their side effect profile. One important clinical consideration is that TCAs can cause cardiac dysrhythmias, making it a standard nursing practice to obtain an ECG before initiating the medication to assess cardiac function and avoid complications. This precaution helps identify any pre-existing heart conduction abnormalities that could be worsened by TCAs. Many patients and even some healthcare professionals may mistakenly associate increased saliva production or insomnia as typical side effects of TCAs. However, TCAs generally cause anticholinergic effects, leading to dry mouth rather than excess saliva. Furthermore, sedation rather than insomnia is more common during the initial weeks of therapy. This sedation effect can actually impair alertness, so nurses should educate patients about these potential impacts. Another frequent side effect to be aware of is orthostatic hypotension, which occurs when standing up too quickly and causes dizziness or lightheadedness. While this can be alarming, it is not considered an emergency. Educating patients to change positions slowly and cautiously helps mitigate the risk of falls. Recognizing that orthostatic hypotension is manageable rather than an emergency aids nursing assessment and patient counseling. For those preparing for the NCLEX exam, practicing questions about the pharmacology and nursing care related to TCAs can enhance understanding and improve test readiness. Using reputable study groups or websites offering daily practice can provide exposure to varied clinical scenarios. Ultimately, mastering the rationale behind medication side effects and patient monitoring will support safe nursing interventions and promote patient safety in clinical practice.
