A nurse is providing teaching about increasing dietary fibre to an antepartum client who reports constipation. Which of the following food selections has the highest fibre content per cup?
Oatmeal.
Cabbage.
Lentils.
Asparagus.
The Correct Answer is C
Choice A rationale:
Oatmeal is a good source of fibre, but its fibre content per cup is not as high as some other options.
Choice B rationale:
Cabbage is a healthy choice with some fibre content, but it does not have as much fibre per cup as lentils.
Choice C rationale:
Lentils have the highest fibre content per cup compared to the other options listed. They are rich in both soluble and insoluble fibre, which helps promote bowel regularity and alleviate constipation.
Choice D rationale:
Asparagus is a nutritious vegetable but does not have as much fibre per cup as lentils.

Correct Answer is D
Explanation
The correct answer is **d. The newborn is beginning to cough**.
Choice A rationale:
An irregular respiratory rate in a newborn is not necessarily an indication for nasopharyngeal suctioning. Irregular respirations can have various causes, and suctioning may not be the appropriate intervention.
Choice B rationale:
A respiratory rate of 32 breaths per minute is within the normal range for a newborn and does not indicate the need for nasopharyngeal suctioning.
Choice C rationale:
A pulse oximetry reading of 91% is low and may indicate the need for intervention, but it does not specifically indicate the need for nasopharyngeal suctioning. Other interventions, such as supplemental oxygen, may be more appropriate.
Choice D rationale:
The newborn beginning to cough is a clear indication that there may be secretions or obstruction in the nasopharynx, and suctioning may be necessary to clear the airway and improve respiratory function.
Correct Answer is C
Explanation
The correct answer is Choice C.
Choice A rationale: Thiazide diuretics cause potassium and chloride loss, leading to metabolic alkalosis, not respiratory alkalosis. Hypokalemia decreases hydrogen ion excretion, increasing bicarbonate levels. Metabolic alkalosis is characterized by pH >7.45 and HCO₃⁻ >26 mEq/L rather than decreased PaCO₂.
Choice B rationale: Vomiting leads to metabolic alkalosis due to gastric acid loss. Hydrogen ion depletion increases bicarbonate concentration, shifting pH above normal. Arterial blood gases typically show increased HCO₃⁻ (>26 mEq/L) with a compensatory increase in PaCO₂ (>45 mmHg), not respiratory alkalosis.
Choice C rationale: Salicylate intoxication initially induces hyperventilation, reducing PaCO₂ levels below 35 mmHg and increasing pH above 7.45, leading to respiratory alkalosis. As toxicity progresses, metabolic acidosis may develop due to lactic acid accumulation, but early stages primarily present with respiratory alkalosis.
Choice D rationale: Hypoventilation leads to CO₂ retention, increasing PaCO₂ above 45 mmHg, forming carbonic acid (H₂CO₃) and causing respiratory acidosis. Blood gases show pH <7.35 with elevated PaCO₂, not respiratory alkalosis, which is caused by excessive CO₂ elimination through hyperventilation.
