The nurse is caring for a client who is postoperative and receiving supplemental oxygen at 2 L/minute via nasal cannula. The oxygen saturation is 89%. Which action should the nurse implement?

Switch to a non-rebreather mask.

Remove the nasal cannula.

Increase the oxygen to 3 L/minute.

Verify the placement of the pulse oximeter.

Answer and Explanation

The Correct Answer is D

Choice A reason: Switching to a non-rebreather mask is not the immediate action to take. Non-rebreather masks deliver a high concentration of oxygen, typically reserved for severe hypoxia. The patient’s oxygen saturation is low, but not critically low. It’s important to first ensure the accuracy of the reading before escalating oxygen delivery methods.

Choice B reason: Removing the nasal cannula is not advisable. The patient is postoperative and may have impaired gas exchange due to anesthesia, pain, or decreased mobility. Removing the supplemental oxygen may worsen the patient’s hypoxemia and increase the risk of complications.

Choice C reason: Increasing the oxygen to 3 L/minute could be a potential action if the oxygen saturation reading is accurate and the patient’s condition does not improve. However, any changes to a patient’s oxygen therapy should be made under the guidance of a healthcare provider. It’s important to first verify the accuracy of the oxygen saturation reading.

Choice D reason: Verifying the placement of the pulse oximeter is the highest priority action. Before making changes to the oxygen flow rate, it’s important to ensure that the oxygen saturation reading is accurate. Incorrect placement or function of the pulse oximeter could lead to inaccurate readings.

Correct Answer is ["B"]

Explanation

Choice A Reason: This is incorrect because nociceptive pain is caused by stimulation of nociceptors, which are sensory receptors that respond to tissue damage or inflammation. Nociceptive pain is usually localized and throbbing or aching.

Choice B Reason: This is correct because neuropathic pain is caused by damage or dysfunction of the nervous system. Neuropathic pain is usually diffuse and burning or shooting.

Choice C Reason: This is incorrect because acute pain is defined by its duration rather than its cause or quality. Acute pain lasts less than six months and usually has an identifiable cause and predictable course.

Choice D Reason: This is incorrect because visceral pain is caused by stimulation of nociceptors in the internal organs. Visceral pain is usually deep and cramping or squeezing.

A. Regular exercise. B. Stress reduction. C. Smoking cessation. D. Low-fat diet.

Correct Answer is C

Explanation

Choice A Reason: This is incorrect because regular exercise is a beneficial lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Smoking cessation has a greater impact on reducing the risk of cardiovascular events and mortality.

Choice B Reason: This is incorrect because stress reduction is a helpful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Smoking cessation has a more direct effect on improving the function and structure of the blood vessels and heart.

Choice C Reason: This is correct because smoking cessation is the most important lifestyle modification for preventing and managing cardiac disease, as smoking is a major modifiable risk factor that can cause atherosclerosis, hypertension, arrhythmias, thrombosis, and myocardial infarction.

Choice D Reason: This is incorrect because a low-fat diet is a useful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Smoking cessation has a stronger influence on lowering the levels of cholesterol and inflammation in the blood.
