1. Which symptom should a healthcare provider identify as typical of the fight-or-flight response?

• A. Pupil dilation
• B. Increased heart rate
• C. Decreased salivation
• D. Decreased peristalsis

Correct answer: B

Rationale: The correct answer is B: Increased heart rate. During the fight-or-flight response, the sympathetic nervous system is activated, causing the release of epinephrine. This hormone triggers an increase in heart rate to supply more blood to the muscles for a rapid response. Pupil dilation occurs to enhance vision in preparation for quick reactions. On the other hand, salivation and peristalsis decrease as the body prioritizes functions necessary for immediate action rather than digestion-related activities. Therefore, choices A, C, and D are incorrect as they do not align with the typical physiological changes associated with the fight-or-flight response.

2. A patient with major depressive disorder is started on venlafaxine. Which class of antidepressant does this medication belong to?

• A. Selective serotonin reuptake inhibitors (SSRIs)
• B. Tricyclic antidepressants (TCAs)
• C. Monoamine oxidase inhibitors (MAOIs)
• D. Serotonin-norepinephrine reuptake inhibitors (SNRIs)

Correct answer: D

Rationale: Venlafaxine is classified as a serotonin-norepinephrine reuptake inhibitor (SNRI). SNRIs work by increasing the levels of both serotonin and norepinephrine in the brain, which helps alleviate symptoms of depression. This mechanism of action distinguishes SNRIs from other classes of antidepressants like SSRIs, TCAs, and MAOIs, making venlafaxine an effective choice for patients with major depressive disorder. Therefore, the correct answer is D. Choice A, SSRIs, primarily target serotonin reuptake only. Choice B, TCAs, work by inhibiting the reuptake of norepinephrine and serotonin, but they are not as selective as SNRIs. Choice C, MAOIs, inhibit the enzyme monoamine oxidase, leading to increased levels of various neurotransmitters, including serotonin and norepinephrine, but they are typically used as second- or third-line agents due to dietary restrictions and potential side effects.

3. The healthcare provider is providing medication education to a patient who has been prescribed lithium to stabilize mood. Which early signs and symptoms of toxicity should the healthcare provider stress to the patient? Select one that does not apply.

• A. Increased attentiveness
• B. Getting up at night to urinate
• C. Improved vision
• D. An upset stomach for no apparent reason

Correct answer: C

Rationale: Early signs of lithium toxicity include gastrointestinal upset, tremors, increased urination, and increased thirst. Improved vision is not a typical early sign of lithium toxicity and should be ruled out as a symptom to watch for.

4. A healthcare professional is teaching a patient about relaxation techniques to manage anxiety. Which technique is the healthcare professional most likely to recommend?

• A. Deep breathing exercises
• B. Physical exercise
• C. Mindfulness meditation
• D. Journaling

Correct answer: A

Rationale: Deep breathing exercises are a widely recommended technique for managing anxiety and promoting relaxation. By focusing on deep, slow breaths, individuals can activate the body's relaxation response, leading to decreased anxiety levels and an overall sense of calm. This technique is easy to learn, can be practiced anywhere, and is often suggested by healthcare professionals as a first-line approach for anxiety management. Physical exercise, mindfulness meditation, and journaling are also beneficial for mental well-being but may not be the first choice when specifically targeting acute anxiety management.

5. Which of the following are symptoms of a panic attack? Select one that does not apply.

• A. Chest pain
• B. Normal breathing
• C. Dizziness
• D. Hot flashes

Correct answer: B

Rationale: Symptoms of a panic attack can include chest pain, shortness of breath, dizziness, and hot flashes. Normal breathing is not a symptom of a panic attack; instead, individuals experiencing a panic attack may often exhibit rapid or shallow breathing patterns. Therefore, the correct answer is B. Choices A, C, and D are typical symptoms associated with panic attacks, making them incorrect answers.
