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:
Cool, clammy skin is not a typical manifestation of hypernatremia (high sodium levels). Hypernatremia is characterized by an excess of sodium in the blood, which typically leads to symptoms such as thirst, dry mucous membranes, and decreased skin turgor. Cool, clammy skin is more often associated with conditions like shock or hypoglycemia.
Choice B rationale:
Increased salivation is not a common manifestation of hypernatremia. Instead, hypernatremia often leads to signs of dehydration, including dry mouth and decreased salivation.
Choice C rationale:
Hypertension is not a direct manifestation of hypernatremia. Hypernatremia can cause increased blood pressure, but it is not one of the typical clinical signs of hypernatremia. Hypertension is more commonly associated with conditions like high sodium intake, kidney disease, or primary hypertension.
Choice D rationale:
A decreased level of consciousness is a significant manifestation of hypernatremia. Elevated sodium levels in the blood can lead to cellular dehydration, affecting brain cells and resulting in neurological symptoms such as confusion, lethargy, and decreased consciousness. Severe hypernatremia can even lead to seizures and coma. .
Correct Answer is A
Explanation
The correct answer is choiceA. Heart rate 50/min.
Choice A rationale:
Atenolol is a beta-blocker that can significantly lower heart rate.A heart rate of 50/min is considered bradycardia (slow heart rate), and administering atenolol could further decrease the heart rate to a dangerously low level. Therefore, the nurse should withhold the medication in this case.
Choice B rationale:
A respiratory rate of 18/min is within the normal range (12-20 breaths per minute) and does not contraindicate the use of atenolol. Therefore, this finding would not require withholding the medication.
Choice C rationale:
An oxygen saturation of 95% is within the normal range (typically 95-100%) and does not contraindicate the use of atenolol. Thus, this finding would not necessitate withholding the medication.
Choice D rationale:
While a blood pressure of 160/94 mm Hg indicates hypertension, atenolol is often prescribed to manage high blood pressure. Therefore, this finding would not require withholding the medication.
