A nurse is setting up a sterile field to perform wound irrigation for a client. Which of the following actions should the nurse take when pouring the sterile solution?
Place sterile gauze over areas of spilled solution within the sterile field.
Hold the irrigation solution bottle with the label facing away from the palm of the hand.
Remove the cap and place it sterile-side up on a clean surface.
Hold the bottle in the center of the sterile field when pouring the solution.
The Correct Answer is C
The correct answer is choice C. Remove the cap and place it sterile-side up on a clean surface.
Choice A rationale:
Placing sterile gauze over areas of spilled solution within the sterile field is not recommended. Spilled solution can compromise the sterility of the field, and covering it with gauze does not restore sterility. Instead, the nurse should avoid spilling solution to maintain the sterile field.
Choice B rationale:
Holding the irrigation solution bottle with the label facing away from the palm of the hand is incorrect. The correct technique is to hold the bottle with the label facing the palm. This prevents the label from getting wet and unreadable, ensuring that the nurse can always identify the solution correctly.
Choice C rationale:
Removing the cap and placing it sterile-side up on a clean surface is the correct action. This maintains the sterility of the cap, preventing contamination when it is replaced on the bottle. Ensuring the cap remains sterile is crucial for maintaining the sterility of the solution.
Choice D rationale:
Holding the bottle in the center of the sterile field when pouring the solution is incorrect. The bottle should be held outside the sterile field to prevent contamination. The solution should be poured carefully to avoid splashing and compromising the sterile field.

Explanation
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.
Correct Answer is C
Explanation
- . Answer and explanation.
The correct answer is choice C, first-degree atrioventricular block.
This is because the PR interval is longer than normal, which indicates a delay in the conduction of electrical impulses from the atria to the ventricles through the AV node. A normal PR interval is 0.12 to 0.2 seconds, or 3 to 5 small squares on the EKG strip.
In this case, the PR interval is 0.35 seconds, which is more than 5 small squares.
Choice A is wrong because atrial fibrillation is a type of arrhythmia where the atria beat irregularly and rapidly, producing chaotic and variable P waves and an irregular ventricular response.
There is no constant PR interval in atrial fibrillation.
Choice B is wrong because complete heart block is a type of arrhythmia where there is no conduction of electrical impulses from the atria to the ventricles, resulting in independent and dissociated atrial and ventricular rhythms.
There are no consistent P waves or PR intervals in complete heart block.
Choice D is wrong because premature atrial complexes are extra beats that originate from the atria and interrupt the normal sinus rhythm.
They produce abnormal P waves that are different from the sinus P waves, and may have a shorter or longer PR interval depending on the timing of the impulse.
However, they do not cause a constant prolongation of the PR interval.
