Normal range for oxygen saturation via pulse oximeter is?
80-100%
93-100%
90-100%
95-100%
The Correct Answer is D
A: An oxygen saturation range of 80-100% is incorrect. Saturation levels below 90% are considered low and may indicate hypoxemia, requiring medical attention.
B: An oxygen saturation range of 93-100% is generally acceptable, but the ideal range is slightly higher to ensure adequate oxygenation.
C: An oxygen saturation range of 90-100% includes levels that are borderline low. While 90% is often used as a threshold for concern, the optimal range is higher.
D: An oxygen saturation range of 95-100% is considered normal and indicates adequate oxygenation of the blood. This range ensures that tissues receive sufficient oxygen to function properly.

Correct Answer is D
Explanation
A: Having the client move in with a family member or close friend can provide emotional support and assistance with daily activities. However, it does not specifically address the safety needs related to hearing loss. While this option can be beneficial, it is not the most direct solution for ensuring the client’s safety in their home environment.
B: Encouraging the client to get a roommate can also provide companionship and assistance. However, like option A, it does not directly address the specific safety concerns associated with hearing loss. The presence of a roommate might help in emergencies, but it is not a guaranteed solution for all safety issues.
C: Increasing the sound on all alarms might seem like a logical step, but it is not effective for someone with full hearing loss. This approach does not ensure that the client will be alerted to emergencies, as they may not hear the alarms regardless of the volume.
D: Installing flashing lights for alarms is the most effective recommendation for a client with full hearing loss. Visual alarms can alert the client to emergencies such as fires or intruders, ensuring their safety. This solution directly addresses the client’s inability to hear auditory alarms and provides a reliable method for emergency alerts.
Correct Answer is B
Explanation
A: Completing proper documentation of the medication error is important but should not be the first action. Immediate assessment of the patient is more critical.
B: Returning to the room to check and assess the patient is the first priority. The nurse needs to determine if the patient has experienced any adverse effects from the medication error and provide appropriate care.
C: Administering the antidote to the patient immediately is only necessary if the medication given has a known antidote and the patient is showing signs of adverse effects. Assessment should come first.
D: Alerting the charge nurse that a medication error has occurred is important for reporting and follow-up but should follow the immediate assessment and care of the patient.
