A nurse is caring for a client who had a right sided stroke and is exhibiting homonymous hemianopsia when eating. Which of the following actions should the nurse take?

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: Narrowed pulse pressure is not a specific manifestation of pneumonia in the older adult client. Pulse pressure is the difference between the systolic and diastolic blood pressure readings. A normal pulse pressure is about 40 mm Hg, and a narrowed pulse pressure is less than 25 mm Hg. A narrowed pulse pressure can indicate various conditions, such as heart failure, shock, or aortic stenosis, but it is not a sign of pneumonia.

Choice B reason: Night sweats are not a common manifestation of pneumonia in the older adult client. Night sweats are episodes of excessive sweating during sleep that can soak the bedding or clothing. Night sweats can have many causes, such as menopause, infections, medications, or cancer, but they are not typically associated with pneumonia.

Choice C reason: Bradycardia is not a usual manifestation of pneumonia in the older adult client. Bradycardia is a slow heart rate, defined as less than 60 beats per minute. Bradycardia can be normal in some people, such as athletes or those who are very fit, or it can be a sign of a problem with the heart's electrical system. Pneumonia does not cause bradycardia, but it can cause tachycardia, which is a fast heart rate, due to the increased oxygen demand and inflammation.

Choice D reason: Confusion is a frequent manifestation of pneumonia in the older adult client. Confusion is a state of impaired awareness, orientation, memory, or judgment. Confusion can occur in older adults with pneumonia due to several factors, such as hypoxia, dehydration, electrolyte imbalance, fever, or infection. Confusion can also increase the risk of complications, such as aspiration, falls, or delirium. Therefore, the nurse should monitor the mental status of the older adult client with pneumonia and report any changes to the provider..
