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: A stroke involving the right cerebral hemisphere can affect the cognitive and emotional functions of the brain, such as judgment, impulse control, and emotional regulation³. This can lead to risky or inappropriate behaviors, such as acting impulsively or disregarding social norms. Therefore, the nurse should monitor the client for poor impulse control and provide appropriate interventions, such as education, cueing, feedback, and environmental modifications.
Choice B reason: A stroke involving the right cerebral hemisphere can affect the visual functions of the brain, such as depth perception, spatial orientation, and visual recognition³. However, the deficits are usually in the left visual field, not the right, because the right side of the brain controls the left side of the body and the environment. Therefore, the nurse should monitor the client for deficits in the left visual field, not the right.
Choice C reason: A stroke involving the right cerebral hemisphere can affect the abstract reasoning functions of the brain, such as understanding metaphors, humor, or sarcasm. However, the ability to discriminate words and letters is more related to the language functions of the brain, which are mainly controlled by the left cerebral hemisphere. Therefore, the nurse should monitor the client for language deficits, such as aphasia or dysarthria, if the stroke involves the left cerebral hemisphere, not the right.
Choice D reason: A stroke involving the right cerebral hemisphere can affect the motor functions of the brain, such as movement, coordination, and balance³. However, the motor retardation, which is a slowing down of physical and mental activity, is more related to the mood functions of the brain, which are mainly controlled by the frontal lobe of the brain. Therefore, the nurse should monitor the client for motor retardation if the stroke involves the frontal lobe, not the right cerebral hemisphere.

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.
