Nursing Elites

1. A client with chronic kidney disease has arterial blood gas values being reviewed by a nurse. Which of the following sets of values should the nurse expect?

• A. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg
• B. pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg
• C. pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg
• D. pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg

Correct answer: A

Rationale: In chronic kidney disease, metabolic acidosis is common due to impaired kidney function leading to reduced bicarbonate excretion. The correct values indicating metabolic acidosis in this scenario are a low pH (acidosis), low bicarbonate (HCO3-) level, and low PaCO2 (compensation through respiratory alkalosis). Therefore, the expected values for a client with chronic kidney disease would be pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg, as depicted in choice A.

2. A client with acute respiratory failure (ARF) may present with which of the following manifestations? (Select one that doesn't apply.)

• A. Severe dyspnea
• B. Decreased level of consciousness
• C. Headache
• D. Nausea

Correct answer: D

Rationale: In acute respiratory failure (ARF), the body is not getting enough oxygen, leading to respiratory distress. Symptoms of ARF typically include severe dyspnea (difficulty breathing), decreased level of consciousness due to hypoxia, and headache from inadequate oxygenation to the brain. Nausea is not a typical manifestation of ARF and would not be expected in this condition.

3. When caring for a newborn with macrosomia born to a mother with diabetes mellitus, which newborn complication should the nurse prioritize care for?

• A. Hypoglycemia
• B. Hypomagnesemia
• C. Hyperbilirubinemia
• D. Hypocalcemia

Correct answer: A

Rationale: In newborns of diabetic mothers with macrosomia, hypoglycemia is the priority focus of care due to the risk of developing low blood sugar levels after birth. Infants born to diabetic mothers are at risk of hypoglycemia because they have been exposed to high glucose levels in utero and produce high levels of insulin. Hypoglycemia can lead to serious complications if not promptly identified and managed, making it crucial for nurses to closely monitor blood glucose levels and provide necessary interventions to prevent adverse outcomes.

4. A client at 22 weeks of gestation with uncontrolled gestational diabetes mellitus may require medication. Which of the following medications would the provider likely prescribe?

• A. Acarbose
• B. Repaglinide
• C. Glyburide
• D. Glipizide

Correct answer: C

Rationale: Glyburide is commonly prescribed for gestational diabetes mellitus when diet and exercise are insufficient to control blood sugar levels. It is considered safe and effective during pregnancy, making it a suitable choice for managing diabetes in pregnant individuals. Acarbose, Repaglinide, and Glipizide are not typically recommended for use in pregnancy due to potential risks to the fetus.

5. When reviewing the arterial blood gas values for a client, a nurse notes a pH of 7.32, PaCO2 of 48 mm Hg, and HCO3 of 23 mEq/L. What does this indicate about the acid-base balance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: A

Rationale: The given values suggest respiratory acidosis. In respiratory acidosis, the pH is low (<7.35), PaCO2 is high (>45 mm Hg), and the HCO3 is normal or slightly elevated. In this scenario, the low pH (7.32) and high PaCO2 (48 mm Hg) indicate respiratory acidosis, where there is an excess of carbon dioxide in the blood, leading to acidification of the body fluids.
