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
Answer and explanation.
The correct answer is choice A. A nontender, protruding abdomen is a normal finding for a 2year-old toddler. This is due to the immature development of the abdominal muscles and the relatively large size of the liver and kidneys in relation to the rest of the body.
Choice B is wrong because the head circumference should be equal to or less than the chest circumference by age 2. A head circumference that exceeds the chest circumference could indicate hydrocephalus or other neurological problems.
Choice C is wrong because the fontanels, or soft spots on the skull, should be closed by age 18 months. Palpable fontanels could indicate dehydration, malnutrition, or congenital disorders.
Choice D is wrong because the natural loss of deciduous teeth, or baby teeth, usually begins around age 6. Premature loss of teeth could indicate dental caries, trauma, or endocrine disorders.
Correct Answer is B
Explanation
The correct answer is choiceb. Waits for 2 min between suctions.
Choice A rationale:
Inserting the catheter without applying suction is correct. Suction should only be applied while withdrawing the catheter to prevent trauma to the tracheal mucosa.
Choice B rationale:
Waiting for 2 minutes between suctions is too long.The appropriate wait time is generally around 20-30 seconds to 1 minute between suction attempts to prevent hypoxia and allow the patient to recover.
Choice C rationale:
Applying suction for 15 seconds is within the recommended duration.Suctioning should not exceed 15 seconds to avoid causing hypoxia and trauma to the tracheal mucosa.
Choice D rationale:
Encouraging the client to cough during suctioning is appropriate.Coughing helps to mobilize secretions and can make suctioning more effective.
