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 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.

3. A client at 10 weeks of gestation reports abdominal pain and moderate vaginal bleeding. The tentative diagnosis is inevitable abortion. Which of the following nursing interventions should be included in the plan of care?

• A. Administer oxygen via nasal cannula
• B. Offer option to view products of conception
• C. Instruct the client to increase potassium-rich foods in the diet
• D. Maintain the client on bed rest

Correct answer: B

Rationale: Offering the client the option to view products of conception after an inevitable abortion can provide closure and support the grieving process. It allows the client to have a visual confirmation of the pregnancy loss, which can aid in emotional healing. Administering oxygen is not a priority in this scenario as there is no indication of respiratory distress. Instructing the client to increase potassium-rich foods is not directly related to managing an inevitable abortion. Bed rest may be recommended, but offering the option to view products of conception is a more appropriate intervention at this time.

4. A healthcare professional is reviewing the laboratory values of a client who has respiratory acidosis. Which of the following findings should the healthcare professional expect?

• A. HCO3- 30 mEq/L
• B. PaCO2 50 mm Hg
• C. pH 7.45
• D. Potassium 3.3 mEq/L

Correct answer: B

Rationale: In respiratory acidosis, the primary disturbance is an increase in PaCO2 levels above the normal range of 35-45 mm Hg. Option B, PaCO2 50 mm Hg, indicates an elevated partial pressure of carbon dioxide, which is consistent with respiratory acidosis. Options A, C, and D are not directly indicative of respiratory acidosis. HCO3- (Option A) is more related to metabolic acidosis or alkalosis, pH (Option C) is within the normal range indicating no acid-base imbalance, and potassium (Option D) levels are not specific to respiratory acidosis.

5. A client with severe preeclampsia is receiving magnesium sulfate IV at 2 g/hr. Which of the following findings indicates that it is safe to continue the infusion?

• A. Diminished deep-tendon reflexes
• B. Respiratory rate of 16/min
• C. Urine output of 50 mL in 4 hours
• D. Heart rate of 56/min

Correct answer: B

Rationale: A respiratory rate of 16/min within the normal range is an essential parameter to monitor when administering magnesium sulfate, as respiratory depression is a potential adverse effect. Diminished deep-tendon reflexes may indicate magnesium toxicity, warranting immediate intervention. A urine output of 50 mL in 4 hours is below the expected amount, suggesting decreased kidney perfusion, which can be exacerbated by magnesium sulfate. A heart rate of 56/min is bradycardic and may indicate magnesium toxicity, requiring assessment and possible discontinuation of the infusion.
