A nurse is teaching a prenatal class about infection prevention at a community center.
Which of the following statements by a client indicates an understanding of the teaching?

The correct answer is: b: Perform the procedure prior to meals.

Choice A rationale: The rationale for Choice A involves understanding the technique of percussion in postural drainage for cystic fibrosis management. Percussion is a component of chest physiotherapy that involves rhythmic clapping or tapping on the chest wall to help loosen and mobilize secretions within the airways. However, holding the hand flat during percussion may not effectively transmit the necessary force to the chest wall for optimal secretion mobilization. Instead, cupping the hands allows for better resonance and transmission of percussion force, enhancing the effectiveness of the procedure.

Choice B rationale: Performing postural drainage prior to meals is the recommended timing for several reasons. Firstly, initiating the procedure before meals allows the child's stomach to be relatively empty, reducing the risk of discomfort, nausea, or vomiting during the procedure. Secondly, performing postural drainage before meals helps prevent aspiration of stomach contents, which can occur if the child vomits during or after the procedure. Aspiration poses significant risks, including lung infection and respiratory distress, particularly in individuals with compromised respiratory function such as those with cystic fibrosis.

Choice C rationale: While bronchodilators may play a role in managing airway obstruction in cystic fibrosis, administering them after postural drainage is not a standard practice. Bronchodilators are typically used to alleviate bronchoconstriction and improve airflow in the lungs. However, their administration after postural drainage may not be directly related to the immediate goals of the procedure, which are to mobilize and clear pulmonary secretions. The timing of bronchodilator administration is often guided by the individual's clinical condition and the presence of symptoms such as wheezing or shortness of breath.

Choice D rationale: Performing postural drainage twice daily may not provide adequate frequency for managing secretions in individuals with cystic fibrosis. The goal of postural drainage is to facilitate the removal of thick, tenacious mucus from the airways to improve respiratory function and reduce the risk of complications such as infections. In cystic fibrosis, mucus clearance is essential for maintaining pulmonary health and preventing exacerbations. Therefore, a more frequent regimen, often including multiple sessions of postural drainage per day, may be necessary to achieve optimal therapeutic outcomes and prevent mucus accumulation and airway obstruction.

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.
