A nurse is collecting data from a client who has shallow respirations and a respiratory rate of 9/min.
Which of the following acid-base imbalances should the nurse expect?
Metabolic acidosis.
Respiratory alkalosis.
Metabolic alkalosis.
Respiratory acidosis.
The Correct Answer is D
Choice A rationale:
A respiratory rate of 9/min and shallow respirations are indicative of hypoventilation, which can lead to an accumulation of carbon dioxide (CO2) in the blood. This condition results in respiratory acidosis (Choice D). In respiratory acidosis, the arterial pH is decreased (acidic) while the PaCO2 (partial pressure of carbon dioxide) is elevated.
Choice B rationale:
Respiratory alkalosis (Choice B) is characterized by a low PaCO2 and an elevated pH due to hyperventilation. Shallow respirations and a respiratory rate of 9/min do not align with this condition, as it typically involves rapid and deep breathing.
Choice C rationale:
Metabolic alkalosis (Choice C) results from a primary excess of bicarbonate (HCO3-) in the blood and is not associated with the given respiratory patterns. Shallow respirations and a low respiratory rate are more likely to lead to an accumulation of CO2, causing respiratory acidosis (Choice D).
Choice D rationale:
The correct answer is choice D. Shallow respirations and a respiratory rate of 9/min indicate hypoventilation, leading to an accumulation of CO2 in the blood. This condition results in respiratory acidosis, where the arterial pH is decreased. The body's compensatory response is to retain bicarbonate to normalize pH, but this can result in an elevated HCO3- level. The primary acid-base imbalance in this case is respiratory acidosis. .

Correct Answer is D
Explanation
Choice A rationale:
Facial flushing. Facial flushing is not typically associated with atelectasis. Atelectasis is the collapse of a portion of the lung, which can lead to decreased oxygenation and respiratory distress but does not directly cause facial flushing. Flushing may be related to other factors such as fever or allergic reactions.
Choice B rationale:
Dry cough. A dry cough can be a common symptom of atelectasis. As the lung tissue collapses and airways become obstructed, it can lead to irritation and a dry, non-productive cough as the body attempts to clear the airway. So, a dry cough is an expected finding in a client with atelectasis.
Choice C rationale:
Decreasing respiratory rate. A decreasing respiratory rate is not typically associated with atelectasis. In fact, atelectasis often leads to an increased respiratory rate as the body tries to compensate for the reduced oxygen exchange. The patient may experience tachypnea (rapid breathing) as a result.
Choice D rationale:
Increasing dyspnea. Increasing dyspnea is a common and expected finding in a client with atelectasis. As lung tissue collapses and oxygen exchange is compromised, the patient will likely experience worsening shortness of breath. This is a concerning symptom and should be closely monitored, as it may indicate a need for intervention to improve lung expansion and oxygenation.
Correct Answer is C
Explanation
Choice A rationale:
"Pitting edema of the lower legs.”. Pitting edema is a common sign of congestive heart failure (CHF), and it often occurs bilaterally in the lower extremities. While this is a potential finding in left-sided heart failure, it is not specific to it.
Choice B rationale:
"Jugular venous distention.”. Jugular venous distention (JVD) is more indicative of right-sided heart failure or elevated central venous pressure. It is not a typical finding in left-sided heart failure.
Choice C rationale:
"Shortness of breath while lying down.”. This is a classic symptom of left-sided heart failure, known as orthopnea. When the patient lies flat, fluid that has accumulated in the lungs can lead to difficulty breathing. Patients with left-sided heart failure often find relief by sleeping with their upper body elevated.
Choice D rationale:
"Right upper quadrant pain.”. Right upper quadrant pain is not a typical finding in left-sided heart failure. It may be associated with issues related to the liver or gallbladder but is not directly related to heart failure.
