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.

The correct answer is choice C.

Choice A rationale:

The nurse applies the sterile drape after cleaning the perineal area. This is correct because the perineal area should be cleaned before applying the sterile drape. Applying the drape first could potentially introduce bacteria to the catheter during insertion, increasing the risk of a urinary tract infection.

Choice B rationale:

The nurse lubricates the indwelling urinary catheter. This is a correct procedure as it helps to minimize discomfort and trauma during catheter insertion.

Choice C rationale:

The nurse separates the patient’s labia with her dominant hand. This is also a correct procedure. The nurse should use her non-dominant hand to separate the labia and expose the urethral meatus, and then use her dominant hand to insert the catheter.

Choice D rationale:

The nurse provides perineal care prior to inserting the urinary catheter. This is a correct procedure. Providing perineal care before inserting a urinary catheter is important to reduce the risk of introducing bacteria into the urinary tract. It’s part of maintaining strict aseptic technique during insertion.
