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 B
Explanation
This is because cotton socks can help keep the feet dry and prevent infections. Wearing clean socks every day can also prevent blisters and injuries from friction.
Choice A is wrong because soaking feet twice daily can make the skin too soft and prone to injury. It can also wash away natural oils that protect the skin.
Choice C is wrong because rounding the edges of toenails when trimming can cause ingrown nails, which can lead to infection and pain. Toenails should be trimmed straight across and filed smoothly.
Choice D is wrong because using moisturizing lotion between the toes can create a moist environment that promotes fungal growth. Moisturizing lotion should be applied to the rest of the feet, but not between the toes.
Some other foot care guidelines for people with diabetes are:
• Inspect your feet daily and look for signs of injury, such as scrapes, cuts, blisters, etc.
• Wash your feet every day in warm water with mild soap.
Hot water and harsh soaps can damage your skin. Check the water temperature with your fingers or elbow before putting your feet in.
• Don’t walk barefoot.
Protect your feet from heat and cold. Wear appropriate-fitting shoes to avoid injury and blisters.
• See a doctor to remove corns or calluses (don’t do it yourself). Don’t use chemical wart removers, razor blades, corn plasters, or liquid corn or callus removers.
• Don’t sit with your legs crossed or stand in one position for long periods of time.
• See your doctor regularly for foot exams and report any problems or changes in your feet. References:
Correct Answer is C
Explanation
This client should be assessed first because they are at risk of hypoglycemia, which is a medical emergency that can cause seizures, coma, or death if not treated promptly.
The nurse should check the client’s blood glucose level again and provide additional carbohydrates or glucose if needed.
Choice A is wrong because a client who is scheduled for a procedure in 1 hr is not in immediate danger and can be assessed later.
The nurse should verify the client’s consent, allergies, and vital signs before the procedure, but this is not a priority over a client with low blood glucose.
Choice B is wrong because a client who received pain medication 30 min ago for postoperative pain is likely to have improved pain relief and does not need immediate assessment.
The nurse should monitor the client’s pain level, vital signs, and respiratory status periodically, but this is not a priority over a client with low blood glucose.
Choice D is wrong because a client who has 100 mL of fluid remaining in his IV bag is not in immediate danger and can be assessed later.
The nurse should change the IV bag when it is empty or nearly empty, but this is not a priority over a client with low blood glucose.
Normal blood glucose levels are between 70 to 100 mg/dL (3.9 to 5.5 mmol/L) when fasting, and less than 140 mg/dL (7.8 mmol/L) two hours after eating. A blood glucose level below 70 mg/dL (3.9 mmol/L) is considered hypoglycemia and requires immediate treatment. Orange juice is a source of simple carbohydrates that can raise blood glucose quickly, but it may not be enough to prevent hypoglycemia in some cases.
