The nurse should always keep which of these drugs at the bedsides of a client with myasthenia gravis

Correct Answer: C

Rationale: The nurse should always keep Tensilon (Edrophonium) at the bedside of a client with myasthenia gravis. Tensilon is a fast-acting cholinesterase inhibitor that can be used for the diagnosis and emergency treatment of myasthenia crisis. It helps improve muscle strength temporarily by increasing the levels of acetylcholine at the neuromuscular junction. Administering Tensilon can help differentiate between a myasthenic crisis (marked improvement in muscle strength) and a cholinergic crisis (no improvement or worsening of muscle weakness). Keeping Tensilon at the bedside allows for prompt administration in case of a myasthenic crisis.

Correct Answer: C

Rationale: The patient's presentation of jaundice, ascites, spider angiomas, elevated serum bilirubin levels, prolonged prothrombin time, and hypoalbuminemia are all indicative of cirrhosis. Cirrhosis is a late stage of liver disease characterized by liver scarring and poor liver function. Jaundice, which is the yellowing of the skin and eyes due to elevated bilirubin levels, is a common manifestation of liver dysfunction seen in cirrhosis. Ascites, the accumulation of fluid in the abdomen, is also a common complication of cirrhosis. Spider angiomas, which are small blood vessels near the skin's surface, are a result of altered blood flow in the liver due to cirrhosis. Prolonged prothrombin time and hypoalbuminemia are consequences of reduced liver synthesis function in cirrhosis. Hepatic encephalopathy and hepatorenal syndrome

Correct Answer: B

Rationale: The laboratory test used to monitor the therapeutic effect of warfarin therapy is the International Normalized Ratio (INR). Warfarin is a commonly prescribed anticoagulant medication that works by inhibiting the action of vitamin K-dependent clotting factors. Maintaining the INR within the target range specific to the indication for anticoagulation (e.g., DVT prevention or treatment) is essential to balance the risk of bleeding and clotting.

Correct Answer: C

Rationale: The first action the nurse should take when a patient post-thyroidectomy develops signs of hypocalcemia is to assess the patient's calcium level. By assessing the patient's calcium level through laboratory testing, the nurse can confirm the presence of hypocalcemia and determine the severity of the condition. This information will guide further interventions, such as administering calcium supplements or notifying the healthcare provider for additional management. It is important to confirm the diagnosis before proceeding with treatment to ensure appropriate and safe care for the patient.

Correct Answer: D

Rationale: Confusion is a potential adverse effect of digoxin therapy. Digoxin toxicity can manifest as various central nervous system symptoms, including confusion, delirium, and disorientation. It is important to monitor for signs of digoxin toxicity in patients taking this medication, especially those with a history of heart failure or renal impairment. Other common signs of digoxin toxicity may include visual disturbances (like halos around lights), gastrointestinal symptoms (like nausea and vomiting), and cardiac arrhythmias. Monitoring serum digoxin levels can help guide therapy and identify toxicity early.
