A nurse is caring for a client who is at 33 weeks of gestation following an amniocentesis.

The nurse should monitor the client for which of the following complications?

The nurse should first administer oxygen at 2 L/min via nasal cannula because the client has signs of hypoxemia (low oxygen saturation) and respiratory distress (increased respiratory rate) that may worsen the chest pain and myocardial ischemia. Oxygen therapy can help improve oxygen delivery to the heart muscle and reduce the workload of the heart.
The nurse should then administer sublingual nitroglycerin as prescribed because nitroglycerin is a vasodilator that can help relieve chest pain by dilating the coronary arteries and improving blood flow to the heart. Nitroglycerin can also lower blood pressure and reduce cardiac preload and afterload, which can decrease myocardial oxygen demand.
Other choices:

• Prepare the client for cardiac catheterization: This may be a later intervention if the chest pain persists or if the client has a confirmed myocardial infarction, but it is not the first priority for the nurse. Cardiac catheterization is an invasive procedure that involves inserting a catheter into a large artery and advancing it to the coronary arteries to visualize any blockages or stenosis. The procedure may also involve angioplasty or stent placement to restore blood flow to the affected area.

• Request a prescription for an increase in statin: This may be a long-term intervention to lower the client’s LDL cholesterol and prevent further plaque formation in the coronary arteries, but it is not an immediate intervention for chest pain. Statins are lipid-lowering drugs that can reduce the risk of cardiovascular events in clients with CAD, but they do not have a direct effect on chest pain or myocardial ischemia.

• Check a STAT cardiac troponin: This may be a diagnostic test to confirm or rule out a myocardial infarction, but it is not an intervention for chest pain. Cardiac troponin is a protein that is released into the bloodstream when there is damage to the heart muscle. Elevated levels of cardiac troponin indicate a myocardial infarction or other cardiac injury.

• Request a prescription for a beta-blocker: This may be an adjunctive therapy to reduce chest pain and prevent complications, but it is not the first-line intervention for chest pain. Beta-blockers are drugs that block the effects of adrenaline on the heart and blood vessels, which can lower heart rate, blood pressure, and myocardial oxygen demand. Beta-blockers can also prevent arrhythmias and reduce mortality in clients with CAD.

Choice A reason:

Measuring the arm circumference above the insertion site daily is appropriate. When planning care for a client scheduled to receive a peripherally inserted central catheter (PICC) in the arm, it is appropriate for the nurse to include measuring the arm circumference above the insertion site daily. This intervention is essential to monitor for any signs of complications, such as edema or swelling, which could indicate thrombosis or infiltration at the insertion site.

Choice B reason:

Administering sedation Administering sedation is not a routine intervention for a PICC insertion procedure is inappropriate. Sedation might be considered for certain procedures, but it is not typically used for PICC insertions. PICC insertions are generally performed with local anaesthesia at the insertion site.

Choice C reason:

Scheduling an MRI post procedure to verify placement An MRI is not typically used to verify the placement of a PICC. The placement of a PICC is usually confirmed using X-ray or other imaging methods that can visualize the catheter's location within the central veins. Post-procedure verification of PICC placement is essential to ensure proper positioning and to prevent complications.

Choice D reason:

Using gauze to secure an arm board to the involved extremity Using gauze to secure an arm board to the involved extremity is not a common practice for securing a PICC. After a PICC insertion, a securement device specifically designed for PICCs is typically used to secure the catheter in place and prevent movement.
