While auscultating a patient's heart sounds, a nurse detects a fourth heart sound (S4). The nurse understands that this finding possibly indicates:.

Pericarditis.

Arterial obstruction or aneurysm.

Forceful atrial contraction to overcome ventricular resistance.

An infectious valvular disorder.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Pericarditis is an inflammation of the pericardium and would not directly cause an S4 heart sound.

Choice B rationale:

Arterial obstruction or aneurysm would cause changes in blood flow, but not specifically an S4 heart sound.

Choice C rationale:

An S4 heart sound is an extra sound that is heard late in diastole just before S1. It occurs due to resistance to blood flow in an enlarged ventricle, often due to forceful atrial contraction to overcome ventricular resistance.

Choice D rationale:

An infectious valvular disorder could cause a variety of heart sounds, but not specifically an S42.

So, the correct answer is C, after analyzing all choices.

Correct Answer is B

Explanation

Choice A rationale:

A brief episode of ventricular tachycardia, or a rapid heart rate, can occur in patients receiving thrombolytic therapy. However, it is not typically a reason to stop the drug infusion.

Choice B rationale:

Bleeding from the gums can be a sign of excessive bleeding, which is a major risk of thrombolytic therapy. This would be a reason to stop the drug infusion.

Choice C rationale:

A decreased level of consciousness can have many causes and is not specifically associated with thrombolytic therapy.

Choice D rationale:

An increase in blood pressure is not typically a reason to stop thrombolytic therapy.

So, the correct answer is B, after analyzing all choices.

A. Patient reports feeling anxious. B. Blood pressure is 90/54 mm Hg. C. Heart monitor shows normal sinus rhythm. D. Patient is restless and agitated.

Correct Answer is B

Explanation

Choice A rationale:

Feeling anxious is not a common side effect of metoprolol.

Choice B rationale:

Metoprolol is a beta-blocker that can lower blood pressure, so a blood pressure of 90/54 mm Hg could indicate a side effect of this medication.

Choice C rationale:

A normal sinus rhythm is expected and does not indicate a side effect of metoprolol.

Choice D rationale:

Restlessness and agitation are not typical side effects of metoprolol.

So, the correct answer is B, after analyzing all choices.
