A nurse is caring for a client who has acute kidney injury (AKI). Which of the following arterial blood gas values would the nurse expect this client to have?
pH 7.49, HCO3 24, PaCO2 30
pH 7.26, HCO3 24, PaCO2 46
pH 7.26, HCO3 14, PaCO2 30
pH 7.49, HCO3 30, PaCO2 40
The Correct Answer is C
Choice A Reason: This choice is incorrect because it indicates respiratory alkalosis, not AKI. Respiratory alkalosis is a condition in which the lungs eliminate too much carbon dioxide (CO2) from the blood, resulting in a low level of CO2 (PaCO2) and a high level of pH. A normal PaCO2 range is 35 to 45 mm Hg, and a normal pH range is 7.35 to 7.45, so a value of 30 mm Hg and 7.49 indicate respiratory alkalosis.
Choice B Reason: This choice is incorrect because it indicates respiratory acidosis, not AKI. Respiratory acidosis is a condition in which the lungs cannot eliminate enough CO2 from the blood, resulting in a high level of CO2 (PaCO2) and a low level of pH. A value of 46 mm Hg and 7.26 indicate respiratory acidosis.
Choice C Reason: This choice is correct because it indicates metabolic acidosis, which is a common complication of AKI. Metabolic acidosis is a condition in which the body produces too much acid or loses too much base, resulting in a low level of bicarbonate (HCO3) and a low level of pH. A normal HCO3 range is 22 to 26 mEq/L, so a value of 14 mEq/L indicates metabolic acidosis. The low PaCO2 value (30 mm Hg) is due to the respiratory compensation mechanism that tries to restore the acid-base balance by increasing the ventilation and eliminating more CO2.
Choice D Reason: This choice is incorrect because it indicates metabolic alkalosis, not AKI. Metabolic alkalosis is a condition in which the body loses too much acid or gains too much base, resulting in a high level of bicarbonate (HCO3) and a high level of pH. A value of 30 mEq/L and 7.49 indicate metabolic alkalosis.

Correct Answer is D
Explanation
Choice A Reason: This choice is incorrect because it reflects the nurse's feelings rather than focusing on the client's needs. Saying "That's a hurtful thing to say" may make the client feel guilty or defensive, and it does not address the underlying cause of the client's anger or frustration.
Choice B Reason: This choice is incorrect because it sounds accusatory and confrontational rather than empathetic and supportive. Asking "Why would you say such a thing?" may make the client feel judged or criticized, and it does not explore the client's feelings or concerns.
Choice C Reason: This choice is incorrect because it dismisses the client's feelings rather than acknowledging them. Saying "Well, that's your opinion" may make the client feel ignored or invalidated, and it does not show respect or compassion for the client.
Choice D Reason: This choice is correct because it invites the client to express their feelings and concerns rather than shutting them down. Saying "Tell me more about that" may make the client feel heard and understood, and it may help to identify the source of their anger or frustration. The nurse can then use therapeutic communication skills such as active listening, reflecting, clarifying, or validating to establish rapport and trust with the client.
Correct Answer is B
Explanation
Choice A Reason: This choice is incorrect because urinary hesitancy is not the priority finding for the nurse to address.
Urinary hesitancy is a difficulty or delay in starting or maintaining a urine stream. It may be caused by various factors such as prostate enlargement, urinary tract infection, medication side effects, or psychological issues. It may cause discomfort, pain, or urinary retention, but it does not pose an immediate threat to the client's life.
ChoiceB Reason: This choice is correct because dysphagia is the priority finding for the nurse to address. Dysphagia is a difficulty or inability to swallow food or liquids. It may be caused by various factors such as stroke, Parkinson's disease, dementia, esophageal cancer, or oral infections. It may cause malnutrition, dehydration, aspiration, or choking, which can lead to serious complications such as pneumonia, sepsis, or death. Therefore, the nurse should assess the client's swallowing function and provide appropriate interventions such as modifying the diet texture, using thickening agents, or teaching swallowing techniques.
ChoiceC Reason: This choice is incorrect because swollen gums are not the priority finding for the nurse to address. Swollen gums are an inflammation or enlargement of the gingival tissue that surrounds the teeth. They may be caused by various factors such as poor oral hygiene, gum disease, vitamin deficiency, medication side effects, or hormonal changes. They may cause bleeding, pain, or infection, but they do not pose an immediate threat to the client's life.
Choice D Reason: This choice is incorrect because pruritus is not the priority finding for the nurse to address. Pruritus is a sensation of itching that affects the skin. It may be caused by various factors such as dry skin, allergies, eczema, psoriasis, liver disease, or kidney disease. It may cause discomfort, scratching, or skin damage, but it does not pose an immediate threat to the client's life.
