A nurse is reinforcing discharge instructions with the parents of an infant who has been prescribed home oxygen and pulse oximetry monitoring.
Which statement by the parents suggests that further instruction is needed?
A. “The pulse oximeter may not be accurate during periods of excessive movement.”
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.
B. “We will inform the doctor if the pulse oximeter consistently reads 100%.”
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.
C. “The probe of the pulse oximeter can be attached to a finger or a toe.”
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.
D. “We will move the probe of the pulse oximeter every 24 hours.”

Full Explanation
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.
Similar Questions
A nurse is caring for a patient with diabetic ketoacidosis and hypoxia.
What is the first action the nurse should take?
A. Obtain a prescription to administer insulin.
Administering insulin is a crucial step in managing diabetic ketoacidosis (DKA), as insulin deficiency is a primary cause of DKA12. However, it is not the first action to take when a patient presents with both DKA and hypoxia. While insulin helps to reduce blood glucose levels and suppress the production of ketones, it does not address the immediate life-threatening condition of hypoxia.
B. Obtain a prescription for supplemental oxygen.
Hypoxia, or low levels of oxygen in the body, is a medical emergency that requires immediate attention. Supplemental oxygen can help increase the oxygen levels in the patient’s blood, thereby alleviating hypoxia. In the context of a patient with DKA and hypoxia, providing supplemental oxygen would be the first action to take to stabilize the patient’s condition before addressing the DKA12.
C. Obtain a prescription to check the patient’s glucose level.
Checking the patient’s glucose level is an important part of managing DKA, as hyperglycemia is a key feature of this condition. However, it is not the first action to take in this scenario. While monitoring glucose levels can guide the administration of insulin and other treatments for DKA, it does not address the immediate threat posed by hypoxia.
D. Obtain a prescription to administer intravenous fluids.
Administering intravenous fluids is another important step in managing DKA12. Dehydration is a common complication of DKA due to excessive urination caused by high blood sugar levels. However, similar to Choices A and C, while it is an important part of treatment, it is not the first action to take when a patient presents with both DKA and hypoxia.

Choice A rationale:
Administering insulin is a crucial step in managing diabetic ketoacidosis (DKA), as insulin deficiency is a primary cause of DKA12. However, it is not the first action to take when a patient presents with both DKA and hypoxia. While insulin helps to reduce blood glucose levels and suppress the production of ketones, it does not address the immediate life-threatening condition of hypoxia.

Supplemental oxygen can help increase the oxygen levels in the patient’s blood, thereby alleviating hypoxia. In the context of a patient with DKA and hypoxia, providing supplemental oxygen would be the first action to take to stabilize the patient’s condition before addressing the DKA12.

While monitoring glucose levels can guide the administration of insulin and other treatments for DKA, it does not address the immediate threat posed by hypoxia.
Choice D rationale:
Administering intravenous fluids is another important step in managing DKA12. Dehydration is a common complication of DKA due to excessive urination caused by high blood sugar levels. However, similar to Choices A and C, while it is an important part of treatment, it is not the first action to take when a patient presents with both DKA and hypoxia.
A charge nurse in a long-term care facility is observing another nurse who is inserting an indwelling urinary catheter into a female patient.
Which action by the nurse should prompt the charge nurse to intervene?
A. The nurse applies the sterile drape after cleaning the perineal area.
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.
B. The nurse lubricates the indwelling urinary catheter.
The nurse lubricates the indwelling urinary catheter. This is a correct procedure as it helps to minimize discomfort and trauma during catheter insertion.
C. The nurse separates the patient’s labia with her dominant hand.
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.
D. The nurse provides perineal care prior to inserting the urinary catheter.
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.

Which finding is a sign of hyperkalemia?
A. Wheezing.
Wheezing is not typically associated with hyperkalemia. It is more commonly related to respiratory conditions.
B. Decreased deep tendon reflexes.
Hyperkalemia can cause decreased deep tendon reflexes due to the effect of high potassium levels on nerve conduction and muscle function.
C. Hypoactive bowel sounds.
Hypoactive bowel sounds are not a common sign of hyperkalemia. They are more often associated with gastrointestinal issues.
D. Cerebral edema.
Cerebral edema is not related to hyperkalemia. It is usually associated with conditions affecting the brain, such as trauma or infections.
