A client is ordered .9mg ondansetron, IV, PRN q6 hours for nausea. The nurse anticipates which of the following sources to cause potential medication error?

Failed communication

Dose miscalculation

Lack of client education

Poor distribution practices

Answer and Explanation

The Correct Answer is B

A) Failed communication: While communication errors can lead to medication mistakes, in this specific scenario, there is no mention of poor communication. The prescription is clear, and the issue is more likely related to the accuracy of the prescribed dose or the nurse’s understanding of it, making "failed communication" a less likely source of error in this case.

B) Dose miscalculation: This is the most likely source of potential error. The medication is ordered as 0.9 mg of ondansetron IV, which is an unusual dosage because the typical dose of ondansetron IV for nausea is usually 4 mg or 8 mg. A dose of 0.9 mg is very specific and could easily be miscalculated, especially if the nurse is not familiar with this specific dosage form or if there’s any confusion regarding the intended dose. This could lead to an error either in preparation or administration of the medication.

C) Lack of client education: While client education is important for many aspects of treatment, it’s not directly related to the potential medication error in this scenario. The nurse’s concern should focus on the accuracy of administering the prescribed dose correctly, not the client’s understanding of the medication.

D) Poor distribution practices: Poor distribution practices may affect the availability or storage of medications, but this is not the likely source of error in this case. The concern here is more about the correct dosage and potential for miscalculation, rather than issues related to drug distribution or storage.

Correct Answer is B

Explanation

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.

Correct Answer is ["20"]

Explanation

1. Determine the concentration of the guaifenesin:

The label states 100 mg/5 mL.

2. Set up a proportion to find the volume (in mL) needed:

100 mg / 5 mL = 400 mg / x mL

3. Solve for x:

Cross-multiply: 100x = 400 * 5

100x = 2000

x = 2000 / 100

x = 20 mL

Answer: The nurse will administer 20 mL to the client.
