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.
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
The use of a Passy Muir speaking valve can be important for communication, but it is not the highest priority for discharge teaching.
Choice B rationale
Having the phone number of the healthcare provider to report complications is important, but it is not the highest priority. The patient needs to know how to prevent and recognize complications first.
Choice C rationale
While having emergency personal identification that the patient is unable to speak is important, it is not the highest priority. The patient’s immediate post-operative needs should be addressed first.
Choice D rationale
The ability to perform tracheostomy care is the highest priority for discharge teaching. This is a new and critical skill that the patient must learn to prevent complications, maintain the airway, and manage their own care at home.
Correct Answer is C
Explanation
Choice A rationale
Muffled heart sounds are not a typical sign of pneumothorax. They are more commonly associated with conditions such as pericardial effusion or cardiac tamponade.
Choice B rationale
Sudden hemoptysis, or coughing up blood, is not a typical sign of pneumothorax. It is more commonly associated with conditions such as pulmonary embolism or lung cancer.
Choice C rationale
Absent breath sounds on the affected side is a typical sign of pneumothorax. When air enters the pleural space and causes the lung to collapse, breath sounds may be absent or significantly decreased on the affected side.
Choice D rationale
A declining respiratory rate is not a typical sign of pneumothorax. In fact, a rapid respiratory rate (tachypnea) is more commonly observed in pneumothorax due to the body’s attempt to compensate for the decreased lung capacity.
