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?
Hematocrit 45%
Platelets 74,000/mm3
Partial thromboplastin time (PTT) 65 seconds
White blood cell count 8,000/mm3
The Correct Answer is B
Choice A reason: 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.
Choice B reason: 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.
Choice C reason: 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.
Choice D reason: 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.

Correct Answer is C
Explanation
Choice A reason: Weighing the client is not a necessary action before administering digoxin, as it does not affect the dosage or effectiveness of the medication. Weighing the client may be important for monitoring fluid balance and edema, but it is not related to digoxin therapy.
Choice B reason: Measuring the client's blood pressure is not a necessary action before administering digoxin, as it does not affect the dosage or effectiveness of the medication. Digoxin is not a blood pressure-lowering medication, but a cardiac glycoside that increases the contractility and efficiency of the heart. Measuring the blood pressure may be important for monitoring hypertension, but it is not related to digoxin therapy.
Choice C reason: Measuring the client's apical pulse is a necessary action before administering digoxin, as it can help determine the safety and appropriateness of the medication. Digoxin can cause bradycardia (slow heart rate) as a side effect, which can be dangerous and symptomatic. The nurse should check the apical pulse for one full minute and withhold the medication if the pulse is below 60 beats per minute or above 100 beats per minute. The nurse should also report any abnormal or irregular rhythms to the provider.
Choice D reason: Offering the client a light snack is not a necessary action before administering digoxin, as it does not affect the absorption or effectiveness of the medication. Digoxin can be taken with or without food. Offering the client a light snack may be important for maintaining nutrition and hydration, but it is not related to digoxin therapy.
Correct Answer is D
Explanation
Choice A reason: Blurred vision is not a common or serious side effect of simvastatin, as it does not affect the eyes or the vision. Blurred vision may be caused by other factors, such as diabetes, hypertension, or eye disorders.
Choice B reason: Orthostatic hypotension is not a common or serious side effect of simvastatin, as it does not affect the blood pressure or the vascular tone. Orthostatic hypotension may be caused by other factors, such as dehydration, anemia, or medication interactions.
Choice C reason: Urinary retention is not a common or serious side effect of simvastatin, as it does not affect the urinary tract or the bladder function. Urinary retention may be caused by other factors, such as prostate enlargement, infection, or nerve damage.
Choice D reason: Muscle weakness is a common and serious side effect of simvastatin, as it can indicate muscle damage or rhabdomyolysis. Rhabdomyolysis is a life-threatening condition that causes the breakdown of muscle tissue and the release of myoglobin into the bloodstream, which can lead to kidney failure. Muscle weakness may be accompanied by muscle pain, tenderness, or dark urine. The nurse should monitor the client's creatine kinase (CK) levels and report any signs of muscle damage to the provider.
