A nurse in an emergency department is assessing a client who is overusing prescribed diuretics and has a sodium level of 127 mEq/L. Which of the following laboratory findings should the nurse expect?
High lipase.
High creatine kinase-MB (CK-MB).
Low hemoglobin.
Low urine specific gravity.
The Correct Answer is D
Choice A rationale:
High lipase is not a typical laboratory finding related to overusing prescribed diuretics and a sodium level of 127 mEq/L. Lipase is an enzyme involved in lipid digestion and is more relevant in assessing pancreatic function.
Choice B rationale:
High creatine kinase-MB (CK-MB) is not associated with overusing prescribed diuretics or hyponatremia (low sodium level). CK-MB is a specific marker for myocardial damage and is usually elevated in conditions like myocardial infarction.
Choice C rationale:
Low hemoglobin is not directly related to overusing prescribed diuretics and a sodium level of 127 mEq/L. Low hemoglobin may indicate anemia or other hematological issues but this is not a typical finding in this scenario.
Choice D rationale:
The correct answer is low urine specific gravity. Overusing diuretics can lead to excessive urination, causing the urine to become more dilute with lower specific gravity. A low urine specific gravity indicates decreased urine concentration and can be a sign of fluid and electrolyte imbalances, including hyponatremia.

Correct Answer is C
Explanation
Choice A rationale:
Preparing an endotracheal tube for intubation is not the first action the nurse should take in this situation. Intubation is an invasive procedure and should be reserved for cases where other, less invasive methods of airway management have failed.
Choice B rationale:
Inserting a plastic oral airway may help maintain the airway in some situations, but it is not the first action to take when the client's airway is obstructing and their oxygen saturation is low.
Choice C rationale:
Providing oxygen using a manual resuscitation bag (bag-valve-mask device) is the correct first action. This allows the nurse to manually assist the client's breathing and deliver oxygen more effectively than just providing supplemental oxygen through a nasal cannula or face mask.
Choice D rationale:
Performing a head tilt with a chin-lift is a basic airway maneuver, but it may not be sufficient in this situation, especially if the airway is completely obstructed. Providing oxygen with a manual resuscitation bag takes precedence.
Correct Answer is D
Explanation
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.
