A nurse is reviewing the ABGs of a client who has pneumonia. The nurse should identify which of the following findings is an indication of respiratory acidosis.
PaO2 86 mm Hg.
pH 7.4.
HCO3 16 mEq/L.
PaCO2 58 mm Hg.
The Correct Answer is D
Choice A rationale:
A PaO2 value of 86 mm Hg is within the normal range (80-100 mm Hg) and does not indicate respiratory acidosis. PaO2 measures the partial pressure of oxygen in arterial blood.
Choice B rationale:
A pH of 7.4 is within the normal range (7.35-7.45) and does not indicate respiratory acidosis. The pH reflects the acidity or alkalinity of the blood.
Choice C rationale:
An HCO3 (bicarbonate) level of 16 mEq/L is within the normal range (22-28 mEq/L) and does not indicate respiratory acidosis. HCO3 is a measure of the metabolic component of the body's acid-base balance.
Choice D rationale:
This is the correct choice. A PaCO2 value of 58 mm Hg is elevated and indicates respiratory acidosis. PaCO2 measures the partial pressure of carbon dioxide in arterial blood, and an elevated value suggests the presence of excess carbon dioxide, leading to acidosis.

Correct Answer is B
Explanation
Choice A rationale:
Increasing the intake of dairy products is not recommended for a client with irritable bowel syndrome (IBS) as dairy can exacerbate symptoms in some individuals, particularly if they are lactose intolerant.
Choice B rationale:
Drinking ten glasses of water each day is a helpful recommendation for clients with IBS. Staying hydrated can aid in digestion and help alleviate symptoms like constipation.
Choice C rationale:
Decreasing daily fiber intake to 20 grams is not advisable for IBS management. Adequate fiber intake is essential for maintaining bowel regularity and overall gut health. Instead, it is recommended to focus on soluble fiber and gradually increase fiber intake to avoid exacerbating symptoms.
Choice D rationale:
Encouraging the intake of clear carbonated fluids is not ideal for clients with IBS. Carbonated beverages can cause bloating and gas, potentially worsening symptoms in individuals with sensitive digestive systems. It is better to recommend non-carbonated, non-caffeinated fluids for hydration.
Correct Answer is B
Explanation
Let's break down the calculation:
Given:
- Patient weight: 154 lbs
- Enoxaparin dosage: 0.75 mg/kg
- Available enoxaparin: 60 mg/0.6 mL
Step 1: Convert pounds to kilograms:
- 1 lb is approximately 0.4536 kg
- So, 154 lbs = 154 * 0.4536 kg/lb = 69.85 kg (approximately 70 kg)
Step 2: Calculate the total dose of enoxaparin:
- Desired dose = 0.75 mg/kg * 70 kg = 52.5 mg
Step 3: Determine the volume to administer:
- We have enoxaparin 60 mg/0.6 mL
- To find the volume for 52.5 mg:
- (52.5 mg / 60 mg) * 0.6 mL = 0.525 mL
- Rounded to the nearest tenth, this is 0.5mL.
Therefore, the nurse should administer 0.5mL of enoxaparin
