A nurse is caring for a client who has an endotracheal tube and is receiving mechanical ventilation. Which of the following actions should the nurse take to reduce the risk of ventilator associated pneumonia?

Choice A reason: Blood glucose levels are not a necessary laboratory test for a client who has tuberculosis and new prescriptions for rifampin and pyrazinamide. Blood glucose levels measure the amount of sugar in the blood and are used to diagnose and monitor diabetes. Rifampin and pyrazinamide do not affect blood glucose levels directly, but they may interact with some medications used to treat diabetes, such as sulfonylureas or metformin. The nurse should advise the client to monitor their blood glucose levels regularly and report any changes to the provider.

Choice B reason: Thyroid function studies are not a required laboratory test for a client who has tuberculosis and new prescriptions for rifampin and pyrazinamide. Thyroid function studies measure the levels of thyroid hormones and thyroid stimulating hormone in the blood and are used to diagnose and monitor thyroid disorders. Rifampin and pyrazinamide do not affect thyroid function directly, but they may interact with some medications used to treat thyroid disorders, such as levothyroxine or propylthiouracil. The nurse should advise the client to take their thyroid medication at least 4 hours before or after rifampin and pyrazinamide and report any symptoms of thyroid imbalance to the provider.

Choice C reason: Gallbladder studies are not a relevant laboratory test for a client who has tuberculosis and new prescriptions for rifampin and pyrazinamide. Gallbladder studies include ultrasound, computed tomography (CT), or magnetic resonance imaging (MRI) scans of the gallbladder and are used to diagnose and monitor gallstones or gallbladder inflammation. Rifampin and pyrazinamide do not affect the gallbladder directly, but they may cause side effects such as nausea, vomiting, or abdominal pain, which can mimic gallbladder problems. The nurse should assess the client for signs of hepatotoxicity, such as jaundice, dark urine, or clay colored stools, and report any findings to the provider.

Choice D reason: Liver function tests are a vital laboratory test for a client who has tuberculosis and new prescriptions for rifampin and pyrazinamide. Liver function tests measure the levels of enzymes, proteins, and bilirubin in the blood and are used to diagnose and monitor liver damage or disease. Rifampin and pyrazinamide are both hepatotoxic drugs, which means they can cause liver injury or failure. The nurse should instruct the client to have liver function tests done before starting the medication regimen and periodically during the treatment. The nurse should also educate the client about the signs and symptoms of hepatotoxicity, such as fatigue, loss of appetite, nausea, vomiting, or yellowing of the skin or eyes, and advise them to stop taking the medication and seek medical attention if they occur.

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.
