A nurse is preparing to insert an indwelling urinary catheter for a patient.
What actions should the nurse plan to take?

Choice A rationale:

Hypertension is not typically a sign of hypokalemia. Hypokalemia, or low potassium levels, can cause symptoms like fatigue, muscle weakness, digestive problems, and frequent urination. Hypertension, or high blood pressure, is not commonly associated with hypokalemia.

Choice B rationale:

Cerebral edema, or swelling in the brain, is not a common symptom of hypokalemia. Hypokalemia is more likely to cause symptoms related to muscle function and digestion, as potassium is an essential mineral that helps regulate muscle contractions, maintain healthy nerve function, and regulate fluid balance.

Choice C rationale:

Muscle weakness is a common symptom of hypokalemia. Potassium helps regulate muscle contractions. When blood potassium levels are low, your muscles produce weaker contractions. This can result in symptoms like muscle weakness and fatigue.

Choice D rationale:

Hyperactive bowel sounds are not typically associated with hypokalemia. Hypokalemia can cause digestive problems, but these are more likely to be issues like constipation rather than increased bowel sounds.

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.
