A nurse is admitting an adolescent who has rubella.

Which of the following actions should the nurse take?

The correct answer is choice C. A client who was just given a glass of orange juice for a low blood glucose level.

This client should be assessed first because they are at risk of hypoglycemia, which is a medical emergency that can cause seizures, coma, or death if not treated promptly.

The nurse should check the client’s blood glucose level again and provide additional carbohydrates or glucose if needed.

Choice A is wrong because a client who is scheduled for a procedure in 1 hr is not in immediate danger and can be assessed later.

The nurse should verify the client’s consent, allergies, and vital signs before the procedure, but this is not a priority over a client with low blood glucose.

Choice B is wrong because a client who received a pain medication 30 min ago for postoperative pain is likely to have improved pain relief and does not need immediate assessment.

The nurse should monitor the client’s pain level, vital signs, and respiratory status periodically, but this is not a priority over a client with low blood glucose.

Choice D is wrong because a client who has 100 mL of fluid remaining in his IV bag is not in immediate danger and can be assessed later.

The nurse should change the IV bag when it is empty or nearly empty, but this is not a priority over a client with low blood glucose.

Normal blood glucose levels are between 70 to 100 mg/dL (3.9 to 5.5 mmol/L) when fasting, and less than 140 mg/dL (7.8 mmol/L) two hours after eating. A blood glucose level below 70 mg/dL (3.9 mmol/L) is considered hypoglycemia and requires immediate treatment. Orange juice is a source of simple carbohydrates that can raise blood glucose quickly, but it may not be enough to prevent hypoglycemia in some cases.

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.
