A client currently prescribed a medication highly metabolized by the CYP 450 recently began smoking due to a stressful life event. True or False: The level of medication will increase in this client.

A) Cerebral Vascular Accident (CVA): While a history of a CVA (stroke) is important to consider when prescribing medications, ondansetron is not contraindicated for clients with a history of CVA. The nurse would need to assess the client’s overall neurological status and risk factors but this condition is not an immediate concern for ondansetron use.

B) Depression: Ondansetron is not typically contraindicated in patients with depression. However, the nurse should be mindful of the potential for interactions with other medications the client may be taking for depression, but there is no direct contraindication between ondansetron and depression itself.

C) Glaucoma: This is the most concerning finding. Ondansetron can increase the risk of complications in clients with glaucoma, particularly narrow-angle glaucoma. Ondansetron has some serotonin receptor-blocking properties that can cause dilation of the pupil, which could increase intraocular pressure in clients with glaucoma. Therefore, this condition would require careful monitoring, and the nurse would need to consult with the healthcare provider before administering ondansetron to a client with glaucoma.

D) Congestive Heart Failure (CHF): While patients with CHF need to be monitored for fluid balance, ondansetron is not contraindicated in clients with CHF. The primary concern in these patients would be potential fluid retention or electrolyte imbalances, but this is generally not a direct concern for the administration of ondansetron itself.

A) Planning: The planning phase of the nursing process involves identifying specific goals and outcomes for the patient based on their condition. In this scenario, the nurse has already administered the medication and is assessing the effectiveness, which is a part of evaluating the plan of care. Planning would have occurred prior to medication administration to decide on interventions, but it is not the phase the nurse is in now.

B) Evaluation: Evaluation is the phase where the nurse assesses whether the nursing interventions and treatments are effective in achieving the desired outcomes. In this scenario, the nurse is evaluating the effect of the baclofen dose by observing whether it reduced muscle spasms and pain. The nurse's focus on assessing the result of the medication and its impact on the client’s condition indicates the evaluation phase of the nursing process.

C) Diagnosis: The diagnosis phase occurs before interventions and involves identifying health problems or conditions that need attention. In this case, a nursing diagnosis such as "impaired mobility" or "pain related to muscle spasticity" might have been formulated earlier, but the focus now is on evaluating the effectiveness of the treatment, not on diagnosing the problem.

D) Implementation: Implementation is the phase where the planned interventions are carried out. Administering baclofen to the client would fall under this phase. However, since the nurse is now assessing the effect of the medication after its administration, this action takes place after the intervention and falls under the evaluation phase, not implementation.

E) Assessment: Assessment is the phase where data is gathered about the patient’s condition, including physical and mental health. In this case, the nurse would have assessed the client initially to determine the need for baclofen, but four hours later, the nurse is evaluating the outcome of the medication, not gathering initial data. Therefore, the action described is not part of the assessment phase but rather the evaluation phase.
