A nurse is positioning a client for a cesarean birth.

To prevent a compromise in placental blood flow during the intraoperative period, which of the following actions should the nurse take?

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.

• B: Heart rate 99/min. This is a finding that requires immediate follow-up because it is above the normal range for a 16-year-old client, which is 60 to 100 beats per minute. A high heart rate could indicate anxiety, stress, pain, infection or other conditions that need to be addressed.

• D: Client experiences nightmares. This is a finding that requires immediate follow-up because it could indicate post-traumatic stress disorder (PTSD), which is a mental health condition that can develop after witnessing or experiencing a traumatic event. PTSD can cause distressing symptoms such as nightmares, flashbacks, intrusive thoughts, avoidance, negative mood and hyperarousal. PTSD can interfere with the client’s daily functioning and well-being and requires professional treatment.

• E: Witnessing their family’s death. This is a finding that requires immediate follow-up because it is the most likely cause of the client’s PTSD symptoms and emotional distress. Witnessing the death of one’s family members is a devastating and traumatic experience that can have lasting effects on the client’s mental health. The client may benefit from grief counseling, trauma-focused therapy, medication or other interventions to help them cope with their loss and trauma.

• H: Smoking marijuana to clear their mind. This is a finding that requires immediate follow-up because it indicates that the client is using an illicit substance to self-medicate their emotional pain. Smoking marijuana can have negative effects on the client’s physical and mental health, such as impairing their memory, cognition, judgment, coordination and motivation. It can also increase the risk of addiction, dependence and withdrawal symptoms. The client may need substance abuse counseling, education, referral or other services to help them quit smoking marijuana and find healthier ways to cope with their feelings.
The other findings do not require immediate follow-up for the following reasons:

• A: BP 122/80 mmHg. This is not a finding that requires immediate follow-up because it is within the normal range for a 16-year-old client, which is 110 to 120/70 to 80 mmHg. A normal blood pressure indicates that the client’s cardiovascular system is functioning well and there are no signs of hypertension or hypotension.

• C: Startles easy during thunderstorm. This is not a finding that requires immediate follow-up because it is a normal reaction to a loud noise or a frightening stimulus. The client admits that they have always been afraid of thunderstorms, which suggests that this is not a new or unusual behavior for them. However, the nurse may want to monitor the client’s anxiety level and provide reassurance and comfort during thunderstorms.

• F: Caregiver reporting client acting differently than usual. This is not a finding that requires immediate follow-up because it is a vague and subjective statement that does not specify how the client is acting differently or what changes have occurred in their behavior. The nurse may want to ask the caregiver for more details and examples of how the client has changed since the traumatic event and assess whether these changes are normal or concerning.

• G: Attends school regularly. This is not a finding that requires immediate follow-up because it indicates that the client is maintaining their academic performance and social interactions despite their trauma and grief. Attending school regularly can provide the client with a sense of routine, structure, support and achievement that can help them cope with their situation. However, the nurse may want to check with the client’s teachers and peers to see if they have noticed any changes in the client’s mood, behavior or participation at school.
