Nursing Elites

1. 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.

2. A nurse in an antepartum unit is triaging clients. Which of the following clients should the nurse see first?

• A. A client who is at 38 weeks of gestation and reports a cough and fever
• B. A client who has missed a period and reports vaginal spotting
• C. A client who is at 14 weeks of gestation and reports nausea and vomiting
• D. A client who is at 28 weeks of gestation and reports of painless vaginal bleeding

Correct answer: D

Rationale:

3. 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.

4. A healthcare professional is reviewing the arterial blood gas results for a client in the ICU who has kidney failure and determines the client has respiratory acidosis. Which of the following findings should the healthcare professional expect?

• A. Widened QRS complexes
• B. Hyperactive deep tendon reflexes
• C. Bounding peripheral pulses
• D. Warm, flushed skin

Correct answer: A

Rationale: Respiratory acidosis is characterized by an increase in carbon dioxide levels in the blood, leading to acidosis. This condition can affect the heart's electrical conduction system, resulting in widened QRS complexes on an electrocardiogram (ECG). Hyperactive deep tendon reflexes, bounding peripheral pulses, and warm, flushed skin are not typically associated with respiratory acidosis.

5. A client at 11 weeks of gestation reports slight occasional vaginal bleeding over the past 2 weeks. Following an examination, the provider informs the client that the fetus has died, indicating a:

• A. Incomplete miscarriage
• B. Missed miscarriage
• C. Inevitable miscarriage
• D. Complete miscarriage

Correct answer: B

Rationale: A missed miscarriage, also known as a silent or delayed miscarriage, occurs when the embryo or fetus has died, but no bleeding or contractions have occurred to expel it from the uterus. In this scenario, the client's experiencing slight occasional vaginal bleeding over the past two weeks indicates a missed miscarriage as the fetus has died, but the body has not recognized the loss or expelled the products of conception.
