A nurse is taking a class about patient safety.

Which of the following statements is true regarding patient safety and prevention of harm?

Medication errors are adverse events.

Errors of execution are usually intentional and occur because of time or resource constraints.

As many as 90% of medication errors are preventable.

Poorly coordinated care and nosocomial infections are examples of errors.

Answer and Explanation

The Correct Answer is C

Choice A rationale
While medication errors are indeed considered adverse events, this statement does not fully capture the scope of patient safety and prevention of harm.
Choice B rationale
Errors of execution are usually unintentional, not intentional. They often occur due to system failures rather than time or resource constraints.
Choice C rationale
It is estimated that as many as 90% of medication errors are preventable. This highlights the importance of safety measures and protocols in healthcare settings to prevent harm to patients.
Choice D rationale
Poorly coordinated care and nosocomial infections are examples of errors, but they represent only a fraction of the potential safety issues in healthcare.

Correct Answer is D

Explanation

Choice A rationale
While it’s true that appetite and sense of smell are closely linked, the return of appetite does not necessarily mean the return of the sense of smell, especially after a total laryngectomy.
Choice B rationale
The body does not develop an ability to smell through the stoma. The sense of smell is primarily mediated by the olfactory nerve (Cranial Nerve I), which is located in the upper part of the nasal cavity.
Choice C rationale
The sense of smell does not typically return after several months following a total laryngectomy. This is because the surgery involves removal of the larynx and separation of the airway from the mouth, nose and throat.
Choice D rationale
Breathing through a stoma after a total laryngectomy does alter the sense of smell. This is because the nose and mouth are bypassed during breathing, and these are the primary routes for smell.

A. Establish a benchmark to identify a standard of performance. B. Compare the number of medication errors before and after the implementation of the measures. C. Conduct a study on the time and cost implications of implementing the change. D. Provide a Questionnaire to the staff to quantify their satisfaction with the changes.

Correct Answer is B

Explanation

Choice A rationale
Establishing a benchmark to identify a standard of performance is a crucial step in any quality improvement process. It provides a reference point against which progress can be measured. However, it does not directly evaluate the effectiveness of the implemented measures.
Choice B rationale
Comparing the number of medication errors before and after the implementation of the measures is the most direct and effective method to evaluate the success of the changes. This method provides quantitative data that can clearly show whether the measures have led to a reduction in medication errors.
Choice C rationale
Conducting a study on the time and cost implications of implementing the change can provide valuable information about the efficiency of the measures. However, it does not directly assess their effectiveness in reducing medication errors.
Choice D rationale
Providing a questionnaire to the staff to quantify their satisfaction with the changes can help to assess the acceptance of the measures among the staff. However, staff satisfaction does not necessarily correlate with the effectiveness of the measures in reducing medication errors.
