A nurse is teaching a client who is to undergo placement of a nontunneled percutaneous central venous access device. Which of the following statements should the nurse include in the teaching?
Placement of the catheter is confirmed by a CT scan.
Your head will be elevated as high as possible while the catheter is inserted.
The catheter will be flushed with saline daily.
You will need to lie flat for 24 hours after the procedure.
The Correct Answer is C
Choice A reason: Catheter placement for a nontunneled central venous access device is typically confirmed by X-ray, not a CT scan, to verify tip placement in the superior vena cava. CT scans are less common due to higher radiation and cost, making this statement inaccurate for standard practice.
Choice B reason: Elevating the head as high as possible during insertion is incorrect, as the Trendelenburg position (head down) is often used to distend veins and reduce air embolism risk. High head elevation could complicate insertion and increase complications, making this instruction inappropriate.
Choice C reason: Flushing the catheter with saline daily maintains patency, preventing clots and ensuring functionality of the nontunneled central venous access device. This is a standard care instruction, reducing infection and occlusion risks, and aligns with evidence-based protocols for central line maintenance, making it correct.
Choice D reason: Lying flat for 24 hours post-procedure is not required for nontunneled central venous catheters. Patients may need brief bed rest (e.g., 30 minutes) to prevent bleeding, but 24 hours is excessive and not evidence-based, making this instruction incorrect and overly restrictive.

Correct Answer is B
Explanation
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.
Correct Answer is C
Explanation
Choice A reason: Dehydration is not directly associated with gastroesophageal reflux, which involves gastric acid backflow. Dehydration affects fluid balance, not reflux mechanisms, so this statement is inaccurate and irrelevant to preterm contractions, making it incorrect.
Choice B reason: Dehydration is not caused by decreased hemoglobin and hematocrit; rather, it may elevate these due to hemoconcentration. This statement reverses the relationship, making it factually incorrect and unrelated to preterm labor risks.
Choice C reason: Dehydration can increase preterm labor risk by reducing uterine blood flow and triggering contractions via oxytocin release. This evidence-based link supports hydration as a preventive measure, making it the correct statement for teaching in this scenario.
Choice D reason: Dehydration is treated with fluid replacement, not calcium supplements, which address bone health or specific deficiencies. This treatment is irrelevant to dehydration or preterm labor, making it an incorrect and inappropriate recommendation.
