A male client tells the RN that he does not want to take the atypical antipsychotic drug, olanzapine (Zyprexa), because of the side effects he experienced when he took the drug for a year. Which experience is most likely related to taking olanzapine?

Correct Answer: A

Rationale: The correct answer is A: Weight gain of 75 lbs. Olanzapine is known to cause significant weight gain as a common side effect. This is due to its impact on appetite control and metabolic processes. Other choices are less likely to be directly related to olanzapine. B, thoughts of wanting to hurt himself, is a serious side effect of olanzapine but not as common as weight gain. C, frequent days with diarrhea, is not a typical side effect of olanzapine. D, altered liver function tests, is a possible side effect of olanzapine but weight gain is more commonly associated with it.

Correct Answer: B

Rationale: The correct answer is B (2 to 4 weeks) because antidepressants typically take around 2 to 4 weeks to start showing noticeable effects. Initially, the medication needs time to build up in the system and adjust serotonin levels in the brain. It takes a few weeks for the neurotransmitter balance to stabilize and for the individual to experience improvements in mood and symptoms. Choice A (1 to 2 weeks) is too soon for significant effects to occur. Choice C (4 to 6 weeks) and D (6 to 8 weeks) are too long for the typical onset of action for most antidepressants.

Correct Answer: A

Rationale: The correct answer is A because encouraging the client to actively participate in assigned activities can help distract him from his paranoid thoughts and promote engagement in therapeutic interventions. This can also help establish a routine and promote socialization. B: Confronting the client may escalate his paranoia and lead to increased distress. C: Limiting interactions may further isolate the client and exacerbate his paranoia. D: Administering PRN medication should be considered if the client becomes agitated or poses a risk to himself or others, but it does not address the underlying issue of paranoia.

Correct Answer: A

Rationale: The correct laboratory test to check for a patient administered with Lithium is serum creatinine. This is crucial because Lithium can affect kidney function, leading to potential kidney damage. Monitoring serum creatinine levels helps in early detection of kidney impairment. The other choices (B: Liver function tests, C: Complete blood count, D: Thyroid function tests) are not directly affected by Lithium administration and are not necessary for routine monitoring in patients taking Lithium.

Correct Answer: A

Rationale: The correct answer is A because dry mouth, blurred vision, and constipation are common side effects of many antidepressants, such as tricyclic antidepressants. These side effects are due to the medications' effects on neurotransmitters in the body. Weight gain, insomnia, and agitation (Option B) are more commonly associated with other classes of antidepressants like SSRIs. Nausea, dizziness, and headaches (Option C) are also common side effects but are not as specific to antidepressants. Fatigue, increased appetite, and sweating (Option D) are not typical side effects of most antidepressants.
