A nurse evaluates a client's arterial blood gas values (ABGs): pH 7.1, PaCO2 70 mm Hg, and HCO3 22 mEq/L. Which intervention does the nurse implement first?
Assess the airway.
Administer prescribed bronchodilators.
Administer prescribed mucolytics.
Provide oxygen.
The Correct Answer is A
A. Assessing the airway is always a priority in any client care situation, especially when there are respiratory abnormalities such as respiratory acidosis. Ensuring a patent airway is crucial to maintain adequate oxygenation and ventilation.
B. Bronchodilators are typically used to treat conditions such as bronchoconstriction in asthma or chronic obstructive pulmonary disease (COPD). However, in the context of respiratory acidosis with an elevated PaCO2, the primary issue is not bronchoconstriction but rather impaired gas exchange due to inadequate ventilation.
C. Mucolytics are medications used to thin mucus and facilitate its removal from the respiratory tract. While they can be beneficial in conditions with thick secretions, they do not address the underlying cause of respiratory acidosis, which is inadequate CO2 elimination.
D. Providing oxygen can help improve oxygenation in clients with respiratory acidosis. However, it is important to note that oxygen alone will not correct the underlying cause of respiratory acidosis (elevated PaCO2). Oxygen therapy is supportive and helps to improve oxygen delivery to tissues while other interventions are addressed.

Correct Answer is C
Explanation
A. Postoperative ileus and significant drainage via an NG tube are more likely to lead to electrolyte losses rather than elevated levels. Elevated magnesium levels are less common and typically associated with conditions such as renal failure or excessive magnesium intake.
B. Calcium levels can be affected by gastrointestinal losses, including drainage via an NG tube. Significant fluid loss can lead to hemoconcentration, potentially causing a relative increase in calcium levels initially. However, prolonged fluid loss can lead to overall depletion of electrolytes, including calcium.
C. When fluids are lost through the NG tube, potassium, which is an intracellular electrolyte, can be lost in large amounts. Prolonged drainage can lead to hypokalemia (decreased potassium levels), which can result in muscle weakness, cardiac dysrhythmias, and other serious complications.
D. Elevated sodium levels (hypernatremia) are more commonly associated with dehydration or excessive sodium intake rather than drainage via an NG tube. In this scenario, sodium levels are less likely to be affected compared to potassium.
Correct Answer is B
Explanation
A. This statement suggests symptoms of vitamin B12 deficiency or glossitis, which are not typical signs of digoxin toxicity. Therefore, it is unlikely to indicate digoxin toxicity.
B. Blurred vision is a common neurological symptom of digoxin toxicity. It occurs due to disturbances in visual acuity and color vision, which can manifest as seeing halos around lights or difficulty focusing. Therefore, this statement is indicative of potential digoxin toxicity.
C. Weight gain can occur due to fluid retention, which is a symptom of heart failure rather than digoxin toxicity. Digoxin toxicity typically presents with neurological and gastrointestinal symptoms rather than weight gain.
D. Constipation is not typically associated with digoxin toxicity. Gastrointestinal symptoms such as nausea, vomiting, and anorexia are more common with digoxin toxicity, but constipation is not a specific indicator.
