A nurse is providing dietary advice to a patient at risk for hypokalemia.
Which food should the nurse recommend as a good source of potassium?

Choice A rationale:

Tachycardia, or a rapid heart rate, is not typically an adverse effect of oxygen therapy. Oxygen therapy is often used to help people with conditions like COPD, COVID-19, emphysema, and sleep apnea get enough oxygen to function and stay well. While tachycardia can be a symptom of these conditions, it is not directly caused by the oxygen therapy itself.

Choice B rationale:

Cracks in the oral mucous membranes can indeed be an adverse effect of oxygen therapy. Oxygen therapy involves the delivery of highly concentrated oxygen, which can cause irritation and dryness in the airways, including the oral mucous membranes. This can lead to cracks and discomfort in the mouth. Therefore, it’s important for healthcare providers to monitor patients receiving oxygen therapy for signs of this adverse effect.

Excessive pulmonary secretions are not typically a direct adverse effect of oxygen therapy. While conditions that often require oxygen therapy, such as pneumonia and COPD, can lead to increased pulmonary secretions, these are symptoms of the underlying disease rather than the oxygen therapy itself.

Choice D rationale:

Poor skin turgor is not typically an adverse effect of oxygen therapy. Skin turgor refers to the elasticity of the skin, and poor skin turgor is often a sign of dehydration. While oxygen therapy can cause dryness of the mucous membranes, it does not typically affect the hydration status of the skin.

Choice A rationale:

The statement “The pulse oximeter may not be accurate during periods of excessive movement” is correct. Pulse oximeters measure the amount of oxygen in the blood by shining light through the skin, and movement can cause the light to scatter, leading to inaccurate readings.

Choice B rationale:

The statement “We will inform the doctor if the pulse oximeter consistently reads 100%” indicates further instruction is needed. A pulse oximeter reading of 100% is not necessarily a cause for concern. It simply means that the hemoglobin is fully saturated with oxygen. However, if the oxygen level is consistently at 100%, it could indicate that the oxygen flow is too high and needs to be adjusted. It’s important to follow the healthcare provider’s instructions regarding the desired oxygen saturation level for the infant.

Choice C rationale:

The statement “The probe of the pulse oximeter can be attached to a finger or a toe” is correct. The probe of a pulse oximeter can indeed be attached to a finger, toe, or even an earlobe. The important thing is that it’s attached to a part of the body with good blood flow. Choice D rationale:

The statement “We will move the probe of the pulse oximeter every 24 hours” is correct. It’s important to move the probe periodically to prevent skin damage, such as pressure sores or burns, especially in infants who have delicate skin.
