A. Naloxone
Naloxone is not the correct medication. Naloxone is an opioid antagonist that reverses the effects of opioid overdose, such as respiratory depression, sedation, and hypotension. Naloxone has no effect on magnesium sulfate, which is a mineral and electrolyte that is used to prevent seizures in clients with preeclampsia or eclampsia.
B. Protamine
Protamine is not the correct medication. Protamine is a heparin antagonist that reverses the effects of heparin overdose, such as bleeding, bruising, and thrombocytopenia. Protamine has no effect on magnesium sulfate, which is not an anticoagulant.
C. Calcium gluconate
Calcium gluconate is the correct medication. Calcium gluconate is a calcium salt that antagonizes the effects of magnesium sulfate overdose, such as hypotension, bradycardia, respiratory depression, and muscle weakness. Calcium gluconate is the antidote for magnesium sulfate toxicity, which can occur when the serum magnesium level is above 7.5 mEq/L. The nurse should monitor the client's vital signs, deep tendon reflexes, and urine output, and report any signs of toxicity to the provider.
D. Flumazenil
Flumazenil is not the correct medication. Flumazenil is a benzodiazepine antagonist that reverses the effects of benzodiazepine overdose, such as drowsiness, confusion, and coma. Flumazenil has no effect on magnesium sulfate, which is not a sedative.

Similar Questions
A nurse is caring for a client who has acute respiratory distress syndrome (ARDS) and requires mechanical ventilation. The client receives a prescription for pancuronium. The nurse recognizes that this medication is for which of the following purposes?
A. Suppress respiratory effort
Suppressing respiratory effort is the correct purpose of pancuronium. Pancuronium is a neuromuscular blocking agent that paralyzes the skeletal muscles, including the respiratory muscles. This prevents the client from breathing spontaneously and allows the mechanical ventilator to control the ventilation. Pancuronium is used to improve oxygenation and prevent barotrauma in clients with ARDS, who have severe hypoxemia and stiff lungs.
B. Decrease chest wall compliance
Decreasing chest wall compliance is not the correct purpose of pancuronium. Chest wall compliance is the measure of how easily the chest wall expands during inspiration. Decreasing chest wall compliance means increasing the resistance to lung expansion, which can worsen the ventilation and oxygenation in clients with ARDS. Pancuronium does not affect the chest wall compliance, but rather the muscle tone.
C. Decrease respiratory secretions
Decreasing respiratory secretions is not the correct purpose of pancuronium. Respiratory secretions are the mucus and fluid that are produced by the respiratory tract to moisten and protect the airways. Decreasing respiratory secretions can cause dryness and irritation of the mucous membranes, which can increase the risk of infection and inflammation. Pancuronium does not affect the respiratory secretions, but rather the nerve impulses.
D. Induce sedation
Inducing sedation is not the correct purpose of pancuronium. Sedation is a state of reduced consciousness, awareness, or responsiveness. Inducing sedation can help to reduce anxiety, pain, and agitation in clients who are mechanically ventilated. Pancuronium does not induce sedation, but rather paralysis. Pancuronium does not affect the central nervous system, but rather the peripheral nervous system. The nurse should administer a sedative agent, such as propofol or midazolam, along with pancuronium to ensure the client's comfort and safety.

A nurse is providing discharge teaching to a client who has a new prescription for warfarin. Which of the following statements by the client indicates an understanding of the teaching?
A. "I'll be sure to eat more foods with vitamin K."
"I'll be sure to eat more foods with vitamin K." is not the correct statement. Vitamin K is a nutrient that helps the blood to clot. Warfarin is an anticoagulant that inhibits the action of vitamin K and prevents the formation of blood clots. Eating more foods with vitamin K can counteract the effect of warfarin and increase the risk of thrombosis. The client should maintain a consistent intake of vitamin K and avoid sudden changes in their diet.
B. "I'll take aspirin for my headaches."
"I'll take aspirin for my headaches." is not the correct statement. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits platelet aggregation and prolongs bleeding time. Taking aspirin with warfarin can increase the risk of bleeding and bruising. The client should avoid taking any NSAIDs without consulting their provider. The client should use acetaminophen or other non-NSAID pain relievers for their headaches.
C. "I'll use my electric razor for shaving."
"I'll use my electric razor for shaving." is the correct statement. Using an electric razor for shaving can reduce the risk of cuts and bleeding. The client should avoid using sharp objects or instruments that can cause injury or trauma. The client should also use a soft toothbrush and floss gently to prevent bleeding gums.
D. "It's okay to have a couple of glasses of wine with dinner each evening."
"It's okay to have a couple of glasses of wine with dinner each evening." is not the correct statement. Alcohol can interact with warfarin and affect its metabolism and effectiveness. Drinking alcohol with warfarin can either increase or decrease the blood levels of warfarin and alter the international normalized ratio (INR), which is a measure of the blood's clotting ability. The client should limit their alcohol intake and monitor their INR regularly.

A nurse is reviewing the laboratory data on a client who has a new prescription for heparin for treatment of a pulmonary embolism. Which of the following data should the nurse report to the provider?
A. Hematocrit 45%
Hematocrit 45% is not the correct data. Hematocrit is the percentage of red blood cells in the blood. The normal range for hematocrit is 37% to 47% for women and 42% to 52% for men. Hematocrit 45% is within the normal range and does not indicate any abnormality related to heparin therapy. Heparin does not affect the production or destruction of red blood cells.
B. Platelets 74,000/mm3
Platelets 74,000/mm3 is the correct data. Platelets are the blood cells that are responsible for clotting and preventing bleeding. The normal range for platelets is 150,000 to 400,000/mm3. Platelets 74,000/mm3 is below the normal range and indicates thrombocytopenia, which is a low platelet count. Thrombocytopenia is a serious complication of heparin therapy that can cause bleeding, bruising, and petechiae. The nurse should report this finding to the provider immediately and stop the heparin infusion.
C. Partial thromboplastin time (PTT) 65 seconds
Partial thromboplastin time (PTT) 65 seconds is not the correct data. PTT is a blood test that measures the time it takes for the blood to clot. The normal range for PTT is 25 to 35 seconds. PTT 65 seconds is above the normal range and indicates that the blood is taking longer to clot. This is an expected effect of heparin therapy, as heparin is an anticoagulant that inhibits the formation of blood clots. The nurse should monitor the PTT and adjust the heparin dose according to the provider's orders and the protocol.
D. White blood cell count 8,000/mm3
White blood cell count 8,000/mm3 is not the correct data. White blood cells are the blood cells that are involved in the immune system and fight infections. The normal range for white blood cells is 4,500 to 11,000/mm3. White blood cell count 8,000/mm3 is within the normal range and does not indicate any abnormality related to heparin therapy. Heparin does not affect the production or function of white blood cells.
