A nurse is caring for a client who has a prescription for metoprolol. The nurse measures the client's vital signs and notes that the client's apical heart rate is 49/min. The nurse should prepare to administer which of the following medications?

(A) Heart murmur: This is the most appropriate answer. Mitral valve stenosis can cause a heart murmur due to turbulent blood flow across the narrowed mitral valve. This is often heard best at the apex of the heart with the patient in the left lateral decubitus position.

(B) Clubbing of the fingers: Clubbing of the fingers is typically associated with conditions that cause chronic hypoxia, such as lung disease or congenital heart disease. It is not a common finding in mitral valve stenosis.

(C) Bradycardia: Mitral valve stenosis does not typically cause bradycardia. In fact, some patients may have a rapid heart rate (tachycardia) due to atrial fibrillation, which is a common complication of mitral valve stenosis.

(D) Barrel chest: A barrel chest is typically associated with chronic obstructive pulmonary disease (COPD) and is not a common finding in mitral valve stenosis. It refers to a rounded, bulging chest that resembles the shape of a barrel. This occurs due to overinflation of the lungs over a long period of time.

(A) Increase the heat in the client’s room: Increasing the heat in the client’s room is not typically recommended for a client experiencing dyspnea. Heat can sometimes make breathing more difficult, and it does not address the underlying cause of the dyspnea.

(B) Perform nasotracheal suctioning for the client: Nasotracheal suctioning can be used to clear the airway in certain situations, but it is not typically the first-line treatment for dyspnea in a client at the end of life. It can be uncomfortable and distressing for the client.

(C) Place the head of the client’s bed flat: Placing the head of the bed flat can actually make breathing more difficult for a client experiencing dyspnea. It is generally more helpful to elevate the head of the bed to facilitate easier breathing.

(D) Administer an opioid narcotic to the client: This is the most appropriate answer. Opioid narcotics can help to relieve dyspnea in clients at the end of life by reducing anxiety, decreasing the sensation of breathlessness, and improving the client’s overall comfort level. The use of opioids in this context should be carefully monitored to manage potential side effects.
