Normal range for oxygen saturation via pulse oximeter is?

80-100%

93-100%

90-100%

95-100%

Answer and Explanation

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 B

Explanation

A: Obtaining a chest x-ray is important for diagnosing potential complications but is not the immediate first action to improve oxygen saturation.

B: Raising the head of the bed helps improve lung expansion and oxygenation. It is a quick and effective first step to increase oxygen saturation.

C: Administering a prescribed analgesic can help with pain management but does not directly address the low oxygen saturation.

D: Administering oxygen at 2 L/min is important but should follow the initial step of raising the head of the bed to optimize breathing.

A. “Once I start feeling better, I will stop taking my antibiotic.” B. “If I am 30 minutes late taking my medication, I should skip that dose.” C. “My parenteral medication must be taken with food.” D. “I will rotate the sites for my transdermal patch.”

Correct Answer is D

Explanation

A: Stopping an antibiotic once feeling better is incorrect. Antibiotics should be taken for the full prescribed course to ensure the infection is fully treated and to prevent antibiotic resistance.

B: Skipping a dose if 30 minutes late is not recommended. Most medications can be taken within a short window of the scheduled time. The patient should follow specific instructions provided by the healthcare provider.

C: Parenteral medications are administered via injection and do not need to be taken with food. This statement indicates a misunderstanding of the medication route.

D: Rotating the sites for a transdermal patch is correct. This practice helps prevent skin irritation and ensures consistent absorption of the medication.
