A nurse is assisting with the care of a client who has respiratory alkalosis and is hyperventilating.
What action should the nurse take?
A. Plan to administer insulin to the client.
Administering insulin to a client who is hyperventilating due to respiratory alkalosis would not be the appropriate action. Insulin is used to lower blood glucose levels in clients with hyperglycemia, such as those with diabetes mellitus. It does not directly address the issues of hyperventilation or respiratory alkalosis.
B. Have the client breathe into a paper bag.
Having the client breathe into a paper bag is the correct action in this case. When a person hyperventilates, they exhale more carbon dioxide (CO2) than they produce. This can lead to a state of respiratory alkalosis, where the blood becomes too alkaline due to the low levels of CO2. By breathing into a paper bag, the client re-inhales some of the exhaled CO2, helping to restore the balance of gases in the blood and alleviate the symptoms of respiratory alkalosis.
C. Plan to administer sodium bicarbonate to the client.
Administering sodium bicarbonate to a client who is hyperventilating and has respiratory alkalosis would not be the appropriate action. Sodium bicarbonate is an alkalinizing agent used to treat conditions where there is too much acid in the body, such as metabolic acidosis. In this case, the client’s body is too alkaline due to the respiratory alkalosis, so administering an alkalinizing agent would exacerbate the condition.
D. Have the client place their head between their knees.
Having the client place their head between their knees would not be the appropriate action for a client who is hyperventilating due to respiratory alkalosis. This position is often used to help alleviate symptoms of dizziness or fainting, but it does not address the underlying issue of the imbalance of gases in the blood due to hyperventilation.

Full Explanation
Choice A rationale:
Administering insulin to a client who is hyperventilating due to respiratory alkalosis would not be the appropriate action. Insulin is used to lower blood glucose levels in clients with hyperglycemia, such as those with diabetes mellitus. It does not directly address the issues of hyperventilation or respiratory alkalosis.
Choice B rationale:
Having the client breathe into a paper bag is the correct action in this case. When a person hyperventilates, they exhale more carbon dioxide (CO2) than they produce. This can lead to a state of respiratory alkalosis, where the blood becomes too alkaline due to the low levels of CO2. By breathing into a paper bag, the client re-inhales some of the exhaled CO2, helping to restore the balance of gases in the blood and alleviate the symptoms of respiratory alkalosis.
Choice C rationale:
Administering sodium bicarbonate to a client who is hyperventilating and has respiratory alkalosis would not be the appropriate action. Sodium bicarbonate is an alkalinizing agent used to treat conditions where there is too much acid in the body, such as metabolic acidosis. In this case, the client’s body is too alkaline due to the respiratory alkalosis, so administering an alkalinizing agent would exacerbate the condition.
Choice D rationale:
Having the client place their head between their knees would not be the appropriate action for a client who is hyperventilating due to respiratory alkalosis. This position is often used to help alleviate symptoms of dizziness or fainting, but it does not address the underlying issue of the imbalance of gases in the blood due to hyperventilation.

A nurse is gathering information on a patient who has pleural effusion.
What symptoms should the nurse anticipate?
A. Crackles heard over the patient’s lung fields.
Crackles are a common symptom of pleural effusion. They are abnormal lung sounds that are heard when a patient with pleural effusion breathes in. The sound is caused by the opening of small airways and alveoli collapsed by fluid, exudate, or lack of aeration during expiration.
B. Crepitus felt on the patient’s chest.
Crepitus is not typically associated with pleural effusion. Crepitus is a crackling or grating sound or feeling produced by air in subcutaneous tissue or by the rubbing together of fragments of broken bone. In the context of respiratory health, crepitus might be felt if there is subcutaneous emphysema, where air gets into tissues under the skin covering the chest wall or neck.
C. Substernal retractions observed on the patient’s chest.
Substernal retractions are not a typical symptom of pleural effusion. Retractions are a sign of respiratory distress, but they are more commonly associated with conditions that cause upper airway obstruction or severe lung disease, such as asthma or pneumonia. Choice D rationale: Dullness upon percussion is a classic sign of pleural effusion. When there is fluid in the pleural space, it prevents the normal resonant sound produced by the air-filled lungs from being heard. Instead, a dull sound is heard when the chest is percussed.
D. Dullness heard when percussing the patient’s lung fields.

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.”

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.
