Nursing Elites

1. A client is admitted to the emergency room with a respiratory rate of 7/min. Arterial blood gases (ABG) reveal the following values. Which of the following is an appropriate analysis of the ABGs? pH 7.22, PaCO2 68 mm Hg, Base excess -2, PaO2 78 mm Hg, Saturation 80%, Bicarbonate 26 mEq/L

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

Correct answer: A

Rationale: The ABG values provided indicate respiratory acidosis. In respiratory acidosis, there is an increase in PaCO2 above the normal range (35-45 mm Hg) leading to a decrease in pH (<7.35). In this case, the pH is 7.22 (below normal) with an elevated PaCO2 of 68 mm Hg. The other values do not suggest metabolic acidosis (which would typically show low bicarbonate levels) or metabolic alkalosis. Therefore, the correct interpretation of the ABGs is respiratory acidosis.

2. 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.

3. A healthcare provider in the emergency department is caring for a client who comes to the emergency department reporting severe abdominal pain in the left lower quadrant. The provider suspects a ruptured ectopic pregnancy. Which of the following signs indicates to the provider the presence of intra-abdominal bleeding?

• A. Chvostek's sign
• B. Cullen's sign
• C. Chadwick's sign
• D. Goodell's sign

Correct answer: B

Rationale: Cullen's sign is the presence of periumbilical ecchymosis indicating intra-abdominal bleeding, which can be associated with a ruptured ectopic pregnancy. Chvostek's sign is a facial spasm related to hypocalcemia. Chadwick's sign is a bluish discoloration of the cervix, vagina, and labia during early pregnancy. Goodell's sign is a softening of the cervix in early pregnancy.

4. A nurse in the antepartum unit is caring for a client who is at 36 weeks of gestation and has pregnancy-induced hypertension. Suddenly, the client reports continuous abdominal pain and vaginal bleeding. The nurse should suspect which of the following comp

• A. Placenta previa
• B. Prolapsed cord
• C. Incompetent cervix
• D. Abruptio placentae

Correct answer: D

Rationale:

5. 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.
