A nurse is preparing to assess fetal heart tones for a client who is at 12 weeks of gestation.

Which of the following actions should the nurse take?

The correct answer is choice C. Taking a hot shower in the morning can help decrease stiffness and improve joint mobility for people with rheumatoid arthritis. This is one of the self-management strategies that can reduce pain and disability.

Choice A is wrong because applying cold packs directly on the skin of the affected joints can cause vasoconstriction and increase inflammation.

Cold therapy should be used with caution and with a barrier between the skin and the ice pack.

Choice B is wrong because biological response modifiers are not used to prevent infection, but to reduce inflammation and slow down joint damage in rheumatoid arthritis.

These medications can actually increase the risk of infection by suppressing the immune system.

Choice D is wrong because clustering physical activities during the day can cause fatigue and joint stress for people with rheumatoid arthritis.

It is better to pace activities throughout the day and take frequent breaks to rest the joints.

Normal ranges for rheumatoid arthritis are based on the disease activity score (DAS), which measures the number of swollen and tender joints, the level of inflammation in the blood, and the patient’s global assessment of health. A DAS below 2.6 indicates remission, a DAS between 2.6 and 3.2 indicates low disease activity, a DAS between 3.2 and 5.1 indicates moderate disease activity, and a DAS above 5.1 indicates high disease activity.

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.
