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
According to the flashcards from Quizlet, a nurse should monitor a client who is at 33 weeks of gestation following an amniocentesis for contractions, as they are a sign of preterm labor and possible uterine rupture. An amniocentesis is a procedure that involves inserting a needle into the amniotic sac to obtain a sample of amniotic fluid for testing. It can cause complications such as bleeding, infection, leakage of fluid, and injury to the fetus or placenta.
Choice A is wrong because it is not a common complication of amniocentesis.
Epigastric pain is more likely to be associated with preeclampsia, a condition that causes high blood pressure and proteinuria in pregnancy. Epigastric pain can indicate severe preeclampsia or HELLP syndrome (hemolysis, elevated liver enzymes, low platelets), which are life- threatening complications that require immediate medical attention.
Choice B is wrong because it is not a direct result of amniocentesis.
Hypertension can occur in pregnancy due to various factors, such as chronic hypertension, gestational hypertension, preeclampsia, or eclampsia. Hypertension can increase the risk of complications such as placental abruption, fetal growth restriction, preterm birth, and maternal stroke.
Choice D is wrong because it is not a typical complication of amniocentesis.
Vomiting can occur in pregnancy due to various causes, such as morning sickness, gastroenteritis, food poisoning, or hyperemesis gravidarum. Vomiting can lead to dehydration, electrolyte imbalance, weight loss, and malnutrition if not treated properly.
Some normal ranges that are relevant for this question are:
- The normal gestational age for delivery is between 37 and 42 weeks.
A baby born before 37 weeks is considered preterm and may have complications such as respiratory distress syndrome, bleeding in the brain, infection, or low blood sugar.
- The normal fetal heart rate is between 110 and 160 beats per minute.
A fetal heart rate below 110 or above 160 can indicate fetal distress or hypoxia.
- The normal amniotic fluid index (AFI) is between 8 and 18 cm.
An AFI below 5 cm is considered oligohydramnios and can indicate fetal growth restriction, kidney problems, or rupture of membranes.
An AFI above 24 cm is considered polyhydramnios and can indicate fetal anomalies, diabetes mellitus, or Rh incompatibility.
Correct Answer is A
Explanation
This statement indicates an understanding of the teaching because it reflects the principle of supply and demand in breastfeeding. The more the baby stimulates the breast, the more milk the mother will produce.
Choice B is wrong because manually expressing milk will not decrease the milk supply. In fact, it can help increase the milk supply by removing more milk from the breast and signaling the body to make more.
Choice C is wrong because the breast is not emptied after 5 to 10 minutes of feeding. The baby should be allowed to nurse until they are satisfied and show signs of fullness, such as releasing the nipple, falling asleep, or turning away from the breast. The average duration of a feeding session can vary from 10 to 45 minutes.
Choice D is wrong because the baby should not always start on the same breast when feeding. The mother should alternate which breast she offers first to ensure both breasts are stimulated and drained equally.
This can help prevent engorgement, mastitis, and low milk supply. A simple way to remember which breast to start with is to wear a bracelet or a clip on the bra strap on the side that needs to be offered next.
