A nurse is teaching a client who has mitral valve stenosis that has not responded to pharmacological therapies about other treatment options. Which of the following statements should the nurse include in their teaching?
"Pentoxifylline can be administered to help the platelets from sticking together and occluding the vessels."
"A heparin bolus is administered and followed with a continuous infusion to help keep the blood thinner."
"A flexible catheter will be inserted into a vessel of the arm, neck, or groin and advanced to the heart to dilate a narrowed or occluded artery."
"A small catheter with a balloon on the end is threaded into a vessel in the groin and advanced to the heart where the balloon will be inflated, and the narrowed valve will be dilated. "
The Correct Answer is D
A) "Pentoxifylline can be administered to help the platelets from sticking together and occluding the vessels": Pentoxifylline is a medication used to improve blood flow by decreasing the viscosity of blood. However, it is not typically used to treat mitral valve stenosis. This statement does not accurately reflect treatment options for this condition.
B) "A heparin bolus is administered and followed with a continuous infusion to help keep the blood thinner": Heparin is an anticoagulant used to prevent blood clot formation, but it is not a treatment for mitral valve stenosis itself. While anticoagulants may be used in certain situations with mitral valve stenosis (such as in the setting of atrial fibrillation), they do not directly address the underlying valve narrowing.
C) "A flexible catheter will be inserted into a vessel of the arm, neck, or groin and advanced to the heart to dilate a narrowed or occluded artery": This statement describes a procedure known as percutaneous transluminal mitral valvuloplasty (PTMV), which is a minimally invasive intervention used to treat mitral valve stenosis. During this procedure, a catheter with a deflated balloon on its tip is inserted into a vessel and guided to the heart, where the balloon is inflated to widen the narrowed valve.
D) "A small catheter with a balloon on the end is threaded into a vessel in the groin and advanced to the heart where the balloon will be inflated, and the narrowed valve will be dilated": This statement accurately describes balloon valvuloplasty, which is a common procedure used to treat mitral valve stenosis. By inflating the balloon within the narrowed valve, the procedure aims to widen the valve opening, thus improving blood flow through the heart.

Correct Answer is B
Explanation
A. The heart's electrical transmission through the atrioventricular (AV) node is unusually slow: This statement does not align with the manifestations of dizziness and palpitations in atrial fibrillation. A slow conduction through the AV node would typically manifest as bradycardia or heart block rather than rapid and irregular palpitations.
B. The heart's electrical signals are rapid, chaotic, and irregular: This is the correct answer. Atrial fibrillation is characterized by rapid, chaotic, and irregular electrical signals in the atria, leading to ineffective atrial contractions and an irregular ventricular response. The irregularity and rapidity of the heart rate can lead to symptoms such as palpitations and dizziness.
C. An early electrical signal occurs before the expected sinoatrial (SA) node signal: This statement does not accurately describe the mechanism of atrial fibrillation. Atrial fibrillation involves disorganized electrical activity in the atria, rather than a single early electrical signal.
D. The SA node sends an electrical signal greater than 100/min: While a heart rate greater than 100/min (tachycardia) is commonly associated with atrial fibrillation, this statement does not fully explain the manifestations of dizziness and palpitations. These symptoms are more directly related to the irregularity and chaotic nature of the heart's electrical signals in atrial fibrillation.
Correct Answer is B
Explanation
B. Provide opportunities for education and continually evaluate the client's preferences and goals for care:
This is the most effective intervention. Providing education and involving the client (to the extent possible) in decision-making helps reduce anxiety and build trust. Even though individuals with Alzheimer's disease may have limited memory and cognitive abilities, ongoing communication about the transition and individualized care plans can help ease the process. Additionally, continuously evaluating the client's preferences and goals ensures that the care plan remains person-centered and aligns with their needs, helping to minimize relocation stress.
