A nurse is providing teaching to a client who is postpartum and interested in information about contraception. Which of the following instructions should the nurse include?

Choice A reason: Fibromyalgia, a chronic pain condition, is not a contraindication for oral contraceptives. Estrogen and progesterone do not exacerbate fibromyalgia’s musculoskeletal or neurological symptoms, as they primarily affect hormonal pathways, making contraceptives safe for use in clients with this condition.
Choice B reason: Hypertension is a contraindication for oral contraceptives, as estrogen increases renin-angiotensin activity, elevating blood pressure. This risks cardiovascular events like stroke or myocardial infarction, especially in clients with existing hypertension, necessitating alternative contraception to avoid vascular complications.
Choice C reason: Iron-deficiency anemia is not a contraindication, as oral contraceptives may reduce menstrual bleeding, improving anemia by decreasing iron loss. Their hormonal effects do not impact erythropoiesis, making them potentially beneficial for anemic clients, unlike hypertension, which poses risks.
Choice D reason: Human papillomavirus (HPV) is not a contraindication, as it affects cervical epithelium, not hormonal pathways. While some studies suggest a weak link to cervical cancer, HPV vaccination and screening mitigate risks, making oral contraceptives safe for clients with HPV.

Choice A reason: Marking drainage output every 48 hours is too infrequent to accurately assess drainage in a closed wound drainage system. Frequent monitoring (e.g., every shift) is needed to track output, detect complications like excessive bleeding, and ensure system functionality, making this intervention inadequate for assessment.
Choice B reason: Stripping the chest tube vigorously is not recommended, as it can increase intrathoracic pressure, risking tissue damage or bleeding. It does not assess drainage amount but manipulates the tube, potentially causing harm. Assessment requires observing output in the collection chamber, making this action incorrect.
Choice C reason: Maintaining the collection chamber below the client’s chest ensures proper drainage by gravity in a closed wound drainage system, like a chest tube. This position prevents backflow and allows accurate measurement of drainage output in the chamber, essential for assessing fluid loss and detecting complications like hemothorax.
Choice D reason: Adding water to the water seal chamber maintains system function but does not directly assess drainage amount. The water seal prevents air re-entry, not measures output. Assessment involves observing and recording drainage in the collection chamber, making this action irrelevant to the question’s focus.
