The nursing is caring for a patient who has had a left radial arterial line inserted 10 minutes ago. To reduce the risk of complications, what is the priority nursing intervention?
Ensure all tubing connections are tightened
Apply a pressure dressing to the insertion site
Perform an Allen's test
Obtain a portable x-ray to confirm placement
The Correct Answer is A
A. Ensure all tubing connections are tightened: Tight tubing connections are critical in preventing accidental disconnection, which can result in rapid blood loss and air embolism. Arterial lines are under high pressure, so securing all connections is a top priority to ensure patient safety and maintain line integrity.
B. Apply a pressure dressing to the insertion site: A transparent occlusive dressing not a pressure dressing is used for arterial lines to allow for site visualization and reduce the risk of infection. A pressure dressing could obscure signs of bleeding or compromise the catheter’s position.
C. Perform an Allen's test: Allen’s test is performed prior to radial arterial line insertion to assess collateral circulation via the ulnar artery for preventing ischemic complications if the radial artery is compromised. Performing the test afterward does not prevent complications and is no longer relevant once the catheter is placed.
D. Obtain a portable x-ray to confirm placement: X-rays are used to confirm the placement of central lines, not peripheral arterial lines like the radial line. Arterial line placement is confirmed by waveform analysis and blood return, not imaging.

Correct Answer is B
Explanation
A. Administer the dose later in the day when their nausea subsides: Delaying the dose does not address the underlying concern of potential digoxin toxicity. Symptoms like nausea and visual disturbances suggest toxicity and require immediate assessment rather than postponement.
B. Assess the client's apical rate: The first and most appropriate nursing action is to assess the apical heart rate for one full minute, as bradycardia is a key indicator of digoxin toxicity. If the rate is below 60 bpm, the dose should be held, and the provider should be notified.
C. Contact the physician for STAT serum potassium level: Hypokalemia increases the risk of digoxin toxicity, but while checking potassium is important, it is not the first step. Assessment of heart rate is more immediately critical in evaluating the need to hold the medication.
D. Administer the client's prescribed dose intravenously: Administering the dose especially IV when the client has symptoms of toxicity could worsen the situation. Digoxin should be held, not given, until further evaluation and provider notification.
Correct Answer is B
Explanation
A. Breast cancer treated with chemotherapy and radiation: While cancer and its treatments can suppress the immune system, they are not direct causes of infectious endocarditis. The condition is more closely related to bacteremia and structural heart damage.
B. Periodontal disease and gum surgery three months ago: Periodontal disease involves chronic bacterial infection of the gums and supporting structures of the teeth, this transient bacteremia can lead to infectious endocarditis. Oral infections and invasive dental procedures can introduce bacteria into the bloodstream, particularly streptococci, which can colonize damaged heart valves and cause infectious endocarditis.
C. Type II diabetic for ten years: Diabetes increases the risk of infection generally, but it is not a specific cause of endocarditis. Without a portal of entry or bacteremia, the condition alone is not strongly associated with endocarditis.
D. Myocardial infarction one year ago: A prior MI may result in reduced cardiac function but does not directly lead to infectious endocarditis unless it has resulted in damaged valves or introduced infection, which is not indicated here.
