A nurse is assessing a client who is 1 day postoperative following a lobectomy and has a chest tube drainage system in place. Which of the following findings by the nurse indicates a need for intervention?

Choice A reason: Attaching a humidifier bottle to the base of the flow meter is a correct action for the nurse to take for a client who has pneumonia and a prescription for oxygen therapy at 5 L/min via nasal cannula. A humidifier bottle adds moisture to the oxygen gas, which can prevent dryness and irritation of the nasal passages and the mucous membranes. A humidifier bottle is recommended for oxygen flow rates above 4 L/min.

Choice B reason: Securing the oxygen tubing to the bed sheet near the client’s head is not a correct action for the nurse to take for a client who has pneumonia and a prescription for oxygen therapy at 5 L/min via nasal cannula. Securing the oxygen tubing to the bed sheet can cause the tubing to kink or twist, which can reduce the oxygen flow or delivery. The nurse should secure the oxygen tubing to the client’s clothing or gown, and ensure that there is enough slack to allow the client to move comfortably.

Choice C reason: Applying petroleum jelly to the nares as needed to soothe mucous membranes is not a correct action for the nurse to take for a client who has pneumonia and a prescription for oxygen therapy at 5 L/min via nasal cannula. Petroleum jelly is a flammable substance that can ignite when exposed to oxygen. The nurse should avoid using petroleum jelly or any other oil-based products on the client’s face or nose when using oxygen therapy. The nurse should use water-based products, such as saline gel or nasal spray, to moisturize the nares and mucous membranes.

Choice D reason: Removing the nasal cannula while the client eats is not a correct action for the nurse to take for a client who has pneumonia and a prescription for oxygen therapy at 5 L/min via nasal cannula. Removing the nasal cannula can cause hypoxia, which is a low level of oxygen in the blood. The nurse should keep the nasal cannula in place while the client eats, and monitor the client’s oxygen saturation and respiratory status. The nurse should also assist the client with eating, and encourage small bites and sips to prevent aspiration.

Choice A reason: History of hypertension is not a nonmodifiable risk factor for developing a stroke, but a modifiable risk factor. Hypertension is a high blood pressure, defined as 140/90 mm Hg or higher. Hypertension can damage the blood vessels and increase the risk of stroke by causing atherosclerosis, aneurysm, or hemorrhage. The nurse should teach the clients to monitor their blood pressure and take medications as prescribed to lower their blood pressure and reduce their stroke risk.

Choice B reason: Genetics is a nonmodifiable risk factor for developing a stroke. Genetics refers to the inherited traits that are passed down from parents to children. Genetics can influence the risk of stroke by affecting the susceptibility to certain conditions, such as sickle cell disease, clotting disorders, or familial hypercholesterolemia, that can increase the risk of stroke. The nurse should teach the clients to know their family history and discuss their genetic risk factors with their provider.

Choice C reason: Obesity is not a nonmodifiable risk factor for developing a stroke, but a modifiable risk factor. Obesity is a condition of having excess body fat, defined as a body mass index (BMI) of 30 or higher. Obesity can increase the risk of stroke by contributing to other risk factors, such as hypertension, diabetes, or high cholesterol. The nurse should teach the clients to maintain a healthy weight and follow a balanced diet and exercise regimen to lower their stroke risk.

Choice D reason: History of smoking is not a nonmodifiable risk factor for developing a stroke, but a modifiable risk factor. Smoking is the inhalation of tobacco or other substances that contain nicotine or other harmful chemicals. Smoking can increase the risk of stroke by damaging the blood vessels, increasing the blood pressure, reducing the oxygen in the blood, and promoting blood clotting. The nurse should teach the clients to quit smoking and avoid exposure to secondhand smoke to lower their stroke risk.
