When a client is receiving acyclovir for the treatment of herpes simplex virus (HSV) encephalitis, the nurse should monitor laboratory values and urine output for signs of adverse reactions, specifically kidney dysfunction.
Acyclovir can cause nephrotoxicity, which is a type of kidney damage that can result in decreased urine output and electrolyte imbalances. Therefore, the nurse should monitor the client's laboratory values, such as serum creatinine and blood urea nitrogen (BUN), which can indicate kidney function. In addition, the nurse should monitor the client's urine output and urine characteristics, such as color and clarity, to ensure that the kidneys are functioning properly. If there are any signs of kidney dysfunction, the nurse should notify the healthcare provider immediately to ensure early intervention and prevent further kidney damage.To monitor for nephrotoxicity, the nurse should monitor the client's laboratory values, such as serum creatinine and blood urea nitrogen (BUN), which are markers of kidney function. A rise in these values may indicate that the kidneys are not functioning properly and could be a sign of kidney damage.

a patient diagnosed with chronic obstructive pulmonary disease reports daily symptoms of dyspnea and cough. which medication will the primary health care provider prescribe?
It is the primary health care provider who will determine which medication to prescribe to the patient. A patient diagnosed with chronic obstructive pulmonary disease and experiencing daily symptoms of dyspnea and cough, may be prescribed with medication such as bronchodilators, inhaled corticosteroids, and phosphodiesterase inhibitors.
Chronic Obstructive Pulmonary Disease, or COPD, is a disease characterized by reduced airflow that makes breathing difficult. It's caused by chronic bronchitis and emphysema, two lung disorders. Chronic bronchitis is a long-term inflammation of the bronchi, which are the tubes that bring air to the lungs, while emphysema is the destruction of the alveoli, or air sacs, in the lungs. Bronchodilators for COPD Bronchodilators are medications that help open up the airways in the lungs.
They relax the muscles surrounding the bronchial tubes, allowing more air to pass through. They're commonly used to relieve shortness of breath caused by COPD. Bronchodilators are given as inhalers, nebulizers, and tablets. Inhaled Corticosteroids for COPD Inhaled corticosteroids are medications that reduce inflammation in the airways. These medications are commonly used to treat asthma, but they can also be used to treat COPD. Inhaled corticosteroids are usually given with a bronchodilator.
Phosphodiesterase Inhibitors for COPD Phosphodiesterase inhibitors are medications that help relax the muscles around the airways. They're used to relieve shortness of breath caused by COPD. They're usually given as tablets. Therefore, it is the primary health care provider who will determine which medication to prescribe to the patient.

a nurse is monitoring a client with a resting heart rate of 120 beats/min who has been diagnosed with sinus tachycardia, which can result from a change in which characteristic of cardiac cells?
Sinus tachycardia can result from a change in which characteristics of cardiac cells: in the automaticity of the cardiac cells.
Sinus tachycardia is an abnormally fast resting heart rate, usually greater than 100 beats per minute. It can be caused by a change in the automaticity of the cardiac cells, which is the ability of the cells to spontaneously generate an action potential.
This property is important in the regulation of heart rate, as cardiac cells with greater automaticity will generate a greater number of action potentials, resulting in a faster heart rate. This can lead to sinus tachycardia in certain cases. When the cardiac cells become more excitable, it is called positive automaticity, which will cause the heart rate to speed up.
Alternatively, negative automaticity will decrease the excitability of the cells and result in a slower heart rate. Therefore, sinus tachycardia can be caused by a change in the automaticity of the cardiac cells, resulting in a higher excitability and a faster heart rate.
