Description:Trousseau's sign, also known as "Trousseau's phenomenon" or "carpopedal spasm," is a medical sign that is associated with hypocalcemia, which is a condition characterized by low levels of calcium in the blood. The sign involves the involuntary contraction of the muscles in the hands and feet, leading to a distinctive posture where the fingers and wrists flex and the feet may also be affected. This can occur when a blood pressure cuff is inflated on the upper arm and maintained at a pressure above the systolic blood pressure for a few minutes. In individuals with hypocalcemia, this can trigger muscle twitching and spasms.

Description:Five percent dextrose (also known as D5W) is considered isotonic when it is in the container. However, once it is introduced into the body and absorbed, it becomes slightly hypotonic because the body's fluids have some solutes in them. In a clinical context, D5W is often referred to as isotonic, but it's important to note that it does have some hypotonic properties when taken into the body. This is why it's crucial to understand the context in which the term "isotonic" is being used.

Description:The given ABG values show a low pH (acidosis) along with a low bicarbonate (HCO3) level, indicating a primary metabolic acidosis. The low pH indicates acidemia, and the low bicarbonate suggests a metabolic cause for this acid-base disturbance. The other values, such as the low PaCO2 (respiratory alkalosis) and the normal PaO2, also contribute to the assessment of metabolic acidosis.

Description:Metabolic acidosis refers to a condition in which the body's pH is decreased due to an accumulation of acids or a loss of bicarbonate. Among the options provided, the patient at risk for metabolic acidosis is: a. Patient with uncontrolled diabetes mellitus In uncontrolled diabetes mellitus, particularly diabetic ketoacidosis (DKA), the body produces excess ketones as a result of using fat for energy instead of glucose. This leads to an accumulation of acidic ketones in the blood, contributing to metabolic acidosis. The other options (b, c, d) are not typically associated with metabolic acidosis: b. Patient with emphysema - Emphysema is a lung condition that can result in respiratory acidosis due to impaired ventilation and retention of carbon dioxide. c. Patient with chronic bronchitis - Chronic bronchitis can also lead to respiratory acidosis due to inadequate removal of carbon dioxide from the lungs. d. Elderly patient receiving IV therapy - This is a broad category and doesn't inherently indicate a risk for metabolic acidosis. The risk depends on the specific IV therapy being administered.

Description:Acute renal failure can lead to the accumulation of metabolic waste products, such as urea and creatinine, which are acidic. This accumulation can disrupt the body's acid-base balance, leading to metabolic acidosis. In acute renal failure, the kidneys are not effectively removing these acidic waste products from the blood, causing a decrease in bicarbonate levels and a decrease in pH, resulting in metabolic acidosis.

Description:The given ABG values show an elevated pH (alkalosis) along with an elevated bicarbonate (HCO3) level, indicating a primary metabolic alkalosis. The pH and bicarbonate values are both higher than normal, suggesting an excess of bicarbonate in the blood.

Description:The given ABG values show a low pH (acidosis) along with an elevated PaCO2 and an elevated bicarbonate (HCO3) level. This indicates a primary respiratory acidosis. The high PaCO2 (respiratory acidosis) is being compensated by the elevated bicarbonate (metabolic compensation), which is in line with the body's attempt to counteract the acidosis caused by the respiratory system.

Description:The given ABG values show a low pH (acidosis) along with a low bicarbonate (HCO3) level, indicating a primary metabolic acidosis. The pH and bicarbonate values are both lower than normal, suggesting an excess of acids in the blood.

Description:Burn injuries, diabetic ketoacidosis, and similar conditions lead to an accumulation of acids in the body, which results in a primary metabolic acidosis. So, the correct answer is:

Description:Vomiting, prolonged gastric suctioning, Cushing syndrome, and hyperaldosteronism can lead to a loss of hydrogen ions or an increase in bicarbonate, resulting in a primary metabolic alkalosis.

Description:Depression of the respiratory center or severe asthma attack can lead to inadequate removal of carbon dioxide, causing an accumulation of carbon dioxide in the blood and resulting in a primary respiratory acidosis.

Description:Excessive elimination of carbon dioxide from the body, such as in cases of hyperventilation, leads to a decrease in carbon dioxide levels in the blood, which can result in a primary respiratory alkalosis.

Description:Liver is present in right hypochondriac region, which is the site for metabolism, so by attaching the probe there, more accurate information regarding peripheral temperature can be obtained.

Description:The scenario described, where a client's pulse rate increases significantly upon changing position from lying down to standing up, along with feeling dizzy, is suggestive of orthostatic hypotension. Orthostatic hypotension is a sudden drop in blood pressure that occurs when a person changes their position, usually from lying down to standing up. This can lead to symptoms like increased heart rate and dizziness.

Description:In this position when the patient bears down or coughs or sneezes, hernia protrudes easily and doctor can observe it easily.

Description:The immediate nursing action in the case of an air embolus is to turn the patient to the left lateral decubitus (side-lying) position. This position helps to trap the air in the right atrium of the heart and prevents it from traveling to the pulmonary circulation, reducing the risk of further complications.

Description:The most accurate method to check the position of a newly placed nasogastric (NG) tube is by placing an order for an X-ray to check its position. This method provides a visual confirmation of the tube's placement, ensuring that it is correctly positioned within the stomach and not in the lungs or elsewhere.

Description:After nasogastric feeding, the head end of the patient's bed should be raised to 30-60 degrees for at least 30 minutes. This helps prevent the risk of aspiration, where the contents of the stomach can flow back into the esophagus and lungs, particularly when the patient is lying flat.

Description:The High Fowler's position, where the head of the bed is elevated to a 90-degree angle or as close to that as is comfortable for the child, helps improve lung expansion and makes breathing easier for someone experiencing respiratory distress. This position allows for better chest expansion and helps alleviate bronchospasm by reducing airway resistance.

Description:Fowler's position is a standard patient position in which the patient is seated in a semi-upright sitting position and may have knees either bent or straight. It is an intervention used to promote oxygenation via maximum chest expansion.

Description:Position the patient on left side, lying with the knees drawn to the abdomen. This cases the passage and flow of fluid into the rectum. Gravity and the anatomical structure of the sigmoid colon also suggest that this will aid enema distribution and retention.

Description:Trendelenburg position promotes venous return in patient with hypovolemic shock.

Description:Side lying position is the best indicated position because it reduces the risk of aspiration.

Description:In the knee-chest position, the patient is positioned with the knees on the bed, chest resting on the knees, and head turned to one side. This position is often used for certain medical procedures or examinations.

Description:Upright position facilitates diaphragm excursion and enhances thorax expansion. So, Fowler’s position helps to relieve dyspnea.
