A nurse is collecting data from a client who has pneumonia and is experiencing acute respiratory acidosis. Which of the following manifestations should the nurse expect to find?

A. Moist mucous membranes: Moist mucous membranes are typically a sign of good hydration and are not usually associated with end-of-life stages. In fact, patients nearing the end of life often experience dryness of the mouth and mucous membranes due to decreased fluid intake and certain medications. This dryness can lead to discomfort and difficulties in swallowing or speaking, which is why oral care is an important part of end-of-life care.

B. Irregular respirations: This is correct. As the body’s systems start to shut down in the final stages of life, irregular respirations, including periods of rapid breathing and pauses (Cheyne-Stokes respirations), can be a common symptom. This happens because the body can no longer effectively remove carbon dioxide, and the automatic process of breathing becomes less coordinated. This can be distressing to witness, but it’s usually not uncomfortable for the patient.

C. Tachycardia: While some patients may experience changes in heart rate, tachycardia is not typically a consistent finding in patients at the end of life. As the body weakens, the heart has to work harder to pump blood, which can sometimes lead to a faster heart rate. However, as the end of life approaches, the heart rate often slows down, and blood pressure decreases.

D. Hypertension: Hypertension, or high blood pressure, is not typically a symptom associated with end-of-life care. In the final stages of life, the body’s systems begin to slow down, and blood pressure often decreases. This is due to a combination of factors, including a slower heart rate and a decrease in the body’s ability to regulate blood pressure. It’s also worth noting that pain, anxiety, and certain medications can temporarily increase blood pressure, even in the end-of-life stages.

A. Headache:

Headache is not typically a clinical manifestation of an acute myocardial infarction. The more common symptoms are related to chest pain, autonomic responses, and cardiovascular changes.

B. Tachycardia:

Tachycardia, or an increased heart rate, is a common symptom during an acute MI. This occurs as the body attempts to compensate for decreased cardiac output and perfusion.

C. Nausea:

Nausea is a frequent symptom associated with an acute MI. It results from the activation of the autonomic nervous system during the heart attack.

D. Diaphoresis:

Diaphoresis, or excessive sweating, is a classic symptom of an acute MI. It occurs due to the sympathetic nervous system's response to pain and stress from the heart attack.

E. Orthopnea:

Orthopnea, or difficulty breathing when lying down, is more commonly associated with congestive heart failure rather than an acute MI. While shortness of breath can occur during an MI, orthopnea is not a primary manifestation.
