If the patient PTT lab level is too long and greater than 80 seconds, the nurse should notify the doctor.
Which doctor’s order should the nurse anticipate?
Continue with the same dosage.
Hold dose.
Increase in dosage.
Decrease in dosage.
The Correct Answer is B
This is because a PTT (partial thromboplastin time) test measures how long it takes for blood to clot. A normal PTT range is between 25 to 35 seconds. If the patient’s PTT is too long and greater than 80 seconds, it means their blood is taking too long to clot and they are at risk of bleeding excessively. The nurse should notify the doctor and expect an order to hold the dose of heparin, a type of anticoagulant that prevents blood clots by prolonging the PTT.
Choice A is wrong because continuing with the same dosage of heparin would not correct the prolonged PTT and could cause more bleeding problems for the patient.
Choice C is wrong because increasing the dosage of heparin would further prolong the PTT and increase the risk of bleeding.
Choice D is wrong because decreasing the dosage of heparin would not be enough to bring the PTT back to normal range and would still pose a bleeding risk for the patient.

Correct Answer is D
Explanation
Simvastatin is a type of drug called a statin, which lowers cholesterol and triglycerides in the blood. Statins work by reducing the amount of cholesterol made by the liver, and the liver produces more cholesterol at night.Therefore, taking simvastatin in the evening can increase its effectiveness.
Choice A is wrong because changing position slowly when rising from a chair is not related to simvastatin use.
This advice is usually given to people who have low blood pressure or take medications that lower blood pressure, such as diuretics or beta blockers.
Choice B is wrong because maintaining a steady intake of green leafy vegetables is not specific to simvastatin use.
This advice is usually given to people who take anticoagulants, such as warfarin, because green leafy vegetables contain vitamin K, which can affect the blood clotting process.
Choice C is wrong because consuming no more than 1 L/day of fluid is not related to simvastatin use.
This advice is usually given to people who have fluid retention or heart failure, because excess fluid can put strain on the heart and lungs.

Propranolol is a beta-blocker that can cause bronchoconstriction and worsen asthma symptoms.
Asthma is a reversible airway disease that is a contraindication for taking propranolol.
Choice A, tachycardia, is not a contraindication for taking propranolol.In fact, propranolol can be used to treat some types of tachycardia, such as atrial fibrillation or supraventricular tachycardia, by slowing down the heart rate.
Choice C, hypertension, is not a contraindication for taking propranolol.Propranolol can be used to treat hypertension by reducing the cardiac output and peripheral resistance.
Choice D, glaucoma, is not a contraindication for taking propranolol.Propranolol does not affect the intraocular pressure or the aqueous humor production.However, some other beta-blockers, such as timolol, can be used to treat glaucoma by lowering the intraocular pressure.
