A nurse in an emergency department is reviewing the medical record of a client who is having an acute myocardial infarction.
Which of the following findings places the client at risk if he receives alteplase?
Family history of malignant hypertension.
Hip arthroplasty 1 week ago.
Chronic obstructive pulmonary disease.
Acute renal failure 6 months ago.
The Correct Answer is B
The correct answer is B. Hip arthroplasty 1 week ago.
Alteplase is a drug that dissolves blood clots by converting plasminogen to plasmin. It can be used for acute ischemic stroke, but it has some contraindications that depend on the indication and the type of administration of the drug. Some common contraindications for alteplase are hypersensitivity, active internal bleeding, history of intracranial hemorrhage, bleeding disorders, and high blood pressure. Other contraindications may vary depending on the specific condition and the time window of treatment. Alteplase can cause serious or fatal bleeding as a side effect.
Choice A is wrong because family history of malignant hypertension is not an absolute contraindication for alteplase, although uncontrolled hypertension (>185 mmHg SBP or >110 mmHg DBP) is.
Choice C is wrong because chronic obstructive pulmonary disease is not a contraindication for alteplase, although it may increase the risk of pulmonary hemorrhage.
Choice D is wrong because acute renal failure 6 months ago is not a contraindication for alteplase, although current use of direct thrombin inhibitors or direct factor Xa inhibitors is.
Normal ranges for blood pressure are <120/80 mmHg for normal, 120-129/<80 mmHg for elevated, 130-139/80-89 mmHg for stage 1 hypertension, and ≥140/≥90 mmHg for stage 2 hypertension.
Normal ranges for platelet count are 150,000 to 450,000 platelets per microliter of blood.
Normal ranges for INR are 0.8 to 1.2 for people who are not taking blood thinners and 2 to 3 for people who are taking warfarin.
Normal ranges for aPTT are 25 to 35 seconds for people who are not taking blood thinners and 46 to 70 seconds for people who are taking heparin.

Correct Answer is A
Explanation
The correct answer is choice A. A client who has a hip fracture and a new onset of tachypnea.
This client has a high risk of developing a pulmonary embolism, which is a life-threatening condition that requires immediate intervention.
Tachypnea is a sign of respiratory distress and hypoxia, which can indicate a pulmonary embolism.
The nurse should assess this client first and notify the provider.
Choice B is wrong because a client who has diabetes mellitus and an HbA1c of 6.8% is wellcontrolled and does not need urgent attention.
The normal range for HbA1c is 4% to 6%, and the goal for diabetic clients is less than 7%.
Choice C is wrong because a client who has epidural analgesia and weakness in the lower extremities is expected to have some degree of motor impairment due to the medication.
The nurse should monitor the client’s sensation, movement, and pain level, but this is not a priority over choice A. Choice D is wrong because a client who has sinus arrhythmia and is receiving cardiac monitoring is not in immediate danger.
Sinus arrhythmia is a normal variation of heart rhythm that occurs with breathing.
The nurse should observe the client’s vital signs and cardiac rhythm, but this is not a priority over choice A.

Correct Answer is B
Explanation
The correct answer is choice B. A client who is 1 day postoperative following a vertebroplasty. A vertebroplasty is a procedure that injects cement into a fractured vertebra to help relieve pain and stabilize the spine. The recovery time for this procedure is usually short and the complications are rare.
Therefore, this client is most likely to be stable and ready for early discharge.
Choice A is wrong because a client who is receiving heparin for deep-vein thrombosis (DVT) needs close monitoring of their blood levels and clotting factors. Heparin is a blood thinner that prevents the clots from getting bigger or breaking loose and traveling to the lungs, which can cause a life-threatening condition called pulmonary embolism (PE).
This client is not a good candidate for early discharge.
Choice C is wrong because a client who has cancer and a sealed implant for radiation therapy needs to be isolated in a special room to prevent exposure of others to radiation. A sealed implant is a small holder that contains a radioactive source that is placed inside or near the tumor to deliver high doses of radiation. This type of internal radiation therapy, also called brachytherapy, can last from several minutes to several days, depending on the type and dose of the radioactive source.
This client is not a good candidate for early discharge.
Choice D is wrong because a client who has COPD and a respiratory rate of 44/min has signs of respiratory distress and possible hypoxemia (low oxygen levels in the blood).
