Correct Answer: A

Rationale: Chest tightness is a potential adverse effect of sumatriptan, a triptan used for cluster headaches, due to its vasoconstrictive effects, which may mimic angina and require immediate evaluation.
Choice B is incorrect because weight gain is not associated with sumatriptan; it is more typical of other medications like antidepressants.
Choice C is incorrect because fever is not a common side effect unless an infection is present.
Choice D is incorrect because tachycardia, not bradycardia, may occur due to sumatriptan's stimulatory effects.

Correct Answer: D

Rationale:
Choice A is wrong because atomoxetine is not an anti-anxiety medication, but a selective norepinephrine reuptake inhibitor (SNRI) used to treat attention deficit hyperactivity disorder (ADH
D). It has no effect on reducing anxiety and can cause side effects such as insomnia, nausea, and increased blood pressure.
Choice B is wrong because encouraging the client to watch television is not a therapeutic intervention for a panic attack. Watching television can increase the stimuli in the client's environment, which can worsen anxiety. The nurse should maintain an environment with low stimulation for the client experiencing a panic attack. Dim lighting, few people, and minimal distractions can assist the nurse to decrease the client's level of anxiety.
Choice C is wrong because teaching the client how to meditate is not appropriate during a panic attack. Meditation is a relaxation technique that can be helpful for preventing or reducing anxiety, but it requires concentration and focus, which are impaired in a panic attack. The nurse should teach the client how to meditate when the client is calm and receptive, not when the client is in crisis. A client who is experiencing a panic attack has a very high level of anxiety and a diminished ability to focus. The nurse should stay with the client and remain calm and reassuring during the panic attack. This can help the client feel safe and supported, and reduce the intensity of the anxiety.

Correct Answer: B

Rationale: Tremors and muscle stiffness are signs of extrapyramidal symptoms (EPS), a serious side effect of haloperidol, a typical antipsychotic, requiring immediate reporting for possible dose adjustment or antiparkinsonian medication.
Choice A is incorrect because dry mouth is a common, less severe side effect that can be managed with hydration or sugar-free gum.
Choice C is incorrect because weight loss is not typical; haloperidol may cause weight gain.
Choice D is incorrect because sedation is an expected side effect and does not require immediate reporting unless excessive.

Correct Answer: A

Rationale: Avoiding all products containing alcohol, including mouthwash, is critical with disulfiram, as it causes a severe reaction (flushing, nausea, vomiting) when alcohol is consumed, deterring alcohol use.
Choice B is incorrect because disulfiram is typically taken at bedtime to minimize side effects like drowsiness, not in the morning.
Choice C is incorrect because a metallic taste is not a common side effect of disulfiram; it is more associated with metronidazole.
Choice D is incorrect because disulfiram should not be discontinued abruptly without provider guidance, even if drinking resumes, to avoid complications.

Correct Answer: A

Rationale: Taking doxycycline with a full glass of water prevents esophageal irritation. Antacids reduce absorption, grapefruit juice is unrelated, and tooth discoloration is a risk in children.
