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
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, a 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 a 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 the 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 C
Explanation
This is an example of a therapeutic communication technique that validates the client’s feelings and encourages them to express their emotions verbally rather than physically.
It also shows empathy and respect for the client’s perspective.
Choice A is wrong because engaging the panic alarm is not the first action to take when interacting with an agitated client.
The nurse should first try to calm the client down by using verbal and nonverbal communication skills, such as maintaining eye contact, speaking in a calm and clear voice, and avoiding sudden movements or gestures.
Engaging the panic alarm should be done only if the client becomes violent or poses a threat to themselves or others.
Choice B is wrong because using a face shield with a mask when providing care to the client is not relevant to the situation.
This is personal protective equipment (PPE) that is used to prevent exposure to infectious agents or body fluids, not to manage agitation.
Using a face shield with a mask may also increase the client’s anxiety or paranoia, as they may perceive it as a sign of hostility or fear.
Choice D is wrong because initiating the seclusion protocol is not appropriate for a client who is agitated, pacing, and speaking loudly.
Seclusion is a restrictive intervention that involves isolating the client in a locked room to prevent harm to themselves or others.
It should be used only as a last resort when less restrictive measures have failed or are contraindicated, and only with a provider’s order and close monitoring.
Secluding an agitated client may escalate their behavior and violate their rights.
Normal ranges for agitation are not applicable, as agitation is not a quantifiable parameter.
However, some tools that can be used to assess agitation include the Richmond Agitation- Sedation Scale (RASS), which ranges from -5 (unarousable) to +4 (combative), and the Agitated Behavior Scale (ABS), which ranges from 14 (no agitation) to 56 (severe agitation).
Correct Answer is A
Explanation
A client who is ambulatory and receiving oxygen should be evacuated first during a fire because they are at risk of fire and explosion from the oxygen source. The nurse should instruct the staff to turn off the oxygen supply, remove the oxygen device from the client, and assist them to walk out of the building using the nearest exit.
Choice B is wrong because a client who uses a wheelchair and is confused is not in immediate danger from the fire. They can be evacuated using a swing carry or an extremity carry by two staff members after the clients who are more vulnerable are evacuated.
Choice C is wrong because a client who is bedridden and wears a hearing aid is not in immediate danger from the fire. They can be evacuated using a cradle drop by one staff member after the clients who are more vulnerable are evacuated.
Choice D is wrong because a client who has a fracture and is in balance suspension traction is not in immediate danger from the fire. They can be evacuated using a special device such as a sked or a sled by two or more staff members after the clients who are more vulnerable are evacuated.
