A nurse is caring for a client who has respiratory acidosis. Which of the following pH levels should the nurse expect?

pH 7.48

pH 7.50

pH 7.31

pH 7.39

Answer and Explanation

The Correct Answer is C

A. pH 7.48:

A pH of 7.48 indicates alkalosis, not acidosis. Respiratory acidosis is characterized by a pH below the normal range (7.35-7.45).

B. pH 7.50:

Similar to choice A, a pH of 7.50 indicates alkalosis, not acidosis.

C. pH 7.31:

This pH value falls below the normal range (7.35-7.45), indicating acidemia. In respiratory acidosis, there is an increase in the partial pressure of carbon dioxide (PaCO2) in the blood, leading to an accumulation of carbonic acid and a decrease in pH.

D. pH 7.39:

A pH of 7.39 falls within the normal range (7.35-7.45), indicating a normal acid-base balance. It does not indicate acidosis.

Correct Answer is B

Explanation

(A) Document the rhythm as normal: Asystole is a serious condition characterized by a flatline ECG, indicating no electrical activity in the heart. It is not a normal rhythm and requires immediate intervention.

(B) Start cardiopulmonary resuscitation (CPR): This is the most appropriate initial action. Asystole is a life-threatening condition that requires immediate intervention. The first step should be to start CPR and call for help.

(c) Prepare the patient for cardioversion: Cardioversion is typically used to treat conditions where the heart is beating irregularly (arrhythmias), but not when there is no electrical activity at all (asystole).

(D) Prepare to administer atropine: Atropine is sometimes used in the treatment of bradycardia (slow heart rate), not asystole. In the case of asystole, epinephrine is more commonly administered during resuscitation efforts.

A. Headache B. Tachycardia C. Nausea D. Diaphoresis E. Orthopnea

Correct Answer is ["B","C","D"]

Explanation

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.
