A nurse is consulting a pharmacological reference about medication compatibility prior to administering warfarin to a client.
Which of the following medications should the nurse identify as being incompatible with warfarin?

Choice A rationale:

Paradoxical chest movement refers to the abnormal inward movement of the chest during inhalation and outward movement during exhalation. It is not a typical finding in pneumothorax. Instead, paradoxical chest movement is often observed in conditions such as flail chest.

Choice B rationale:

Reduced right-sided breath sounds are a common finding in right pneumothorax. Air in the pleural space can cause lung collapse, leading to decreased or absent breath sounds on the affected side.

Choice C rationale:

High-pitched stridor is a sound heard during inspiration and indicates upper airway obstruction, often due to conditions like croup or epiglottitis. It is not a characteristic finding in pneumothorax.

Choice D rationale:

Intercostal retractions occur when the tissues between the ribs are pulled inward during inspiration. While retractions can be seen in various respiratory distress conditions, they are not specific to pneumothorax.

The correct answer is D. Contractions.

Choice A Reason: Hypertension Hypertension in pregnancy is a condition that can occur independently of an amniocentesis and is typically monitored throughout the pregnancy. It is characterized by a sustained high blood pressure of 140/90 mmHg or higher. While hypertension is a concern in pregnancy, it is not a direct complication of amniocentesis. Normal ranges for blood pressure in the third trimester are 101.6 to 143.5 mmHg systolic and 62.4 to 94.7 mmHg diastolic.

Choice B Reason: Vomiting Vomiting is not a typical complication following an amniocentesis. It may be associated with other conditions during pregnancy such as hyperemesis gravidarum or gastrointestinal disturbances but is not directly related to the procedure of amniocentesis.

Choice C Reason: Epigastric Pain Epigastric pain is typically associated with conditions like preeclampsia or other gastrointestinal issues in pregnancy, not with amniocentesis. It is characterized by pain in the upper abdomen and is not a common complication post-amniocentesis.

Choice D Reason: Contractions After an amniocentesis, especially at 33 weeks of gestation, monitoring for contractions is crucial because they can indicate preterm labor, which is a known risk associated with the procedure. The normal range for contractions would be none to infrequent Braxton-Hicks contractions, which are not regular and do not signify labor.
