Nursing Elites

1. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

2. The nurse is preparing to care for a child with a diagnosis of intussusception. The nurse reviews the child's record and expects to note which sign of this disorder documented?

• A. Watery diarrhea
• B. Ribbon-like stools
• C. Profuse projectile vomiting
• D. Bright red blood and mucus in the stools

Correct answer: D

Rationale: Intussusception is a condition where a part of the bowel slides into the next section, causing an obstruction. The classic presentation includes severe abdominal pain that is crampy, intermittent, and may cause the child to draw knees to the chest. While vomiting can occur, it is not typically projectile in nature. A key hallmark of intussusception is the passage of bright red blood and mucus in the stools, often described as currant jelly-like. Watery diarrhea and ribbon-like stools are not typical signs of intussusception and should not be expected in a child with this condition.

3. To detect possible complications in a patient with severe cirrhosis who has bleeding esophageal varices, it is most important for the nurse to monitor

• A. bilirubin levels.
• B. ammonia levels.
• C. potassium levels.
• D. prothrombin time.

Correct answer: B

Rationale: In a patient with severe cirrhosis and bleeding esophageal varices, monitoring ammonia levels is crucial. Severe liver dysfunction impairs the metabolism of protein in the GI tract, leading to increased ammonia levels. Elevated ammonia levels can result in hepatic encephalopathy, a serious complication. Monitoring bilirubin levels is important for assessing liver function and jaundice but may not directly reflect the risk of complications from bleeding esophageal varices. Potassium levels are important but not the most critical in this scenario. Prothrombin time is essential for evaluating coagulation status but does not directly relate to the risk of complications from bleeding esophageal varices in this patient.

4. What should the nurse in the emergency department do first for a new patient who is vomiting blood?

• A. Insert a large-gauge IV catheter.
• B. Draw blood for coagulation studies.
• C. Check blood pressure (BP), heart rate, and respirations.
• D. Place the patient in the supine position.

Correct answer: C

Rationale: The nurse's initial action should focus on assessing the patient's hemodynamic status by checking vital signs like blood pressure, heart rate, and respirations. This assessment will help determine the patient's immediate needs and guide further interventions. Drawing blood for coagulation studies and inserting an IV catheter are important steps, but they can follow the initial assessment of vital signs. Placing the patient in the supine position can be risky without first assessing the patient's vital signs, as aspiration is a concern. Therefore, assessing vital signs is the priority to ensure appropriate and timely care for the patient.

5. A 24-year-old female is admitted to the ER for confusion. This patient has a history of a myeloma diagnosis, constipation, intense abdominal pain, and polyuria. Based on the presenting signs and symptoms, which of the following would you most likely suspect?

• A. Diverticulosis
• B. Hypercalcemia
• C. Hypocalcemia
• D. Irritable bowel syndrome

Correct answer: B

Rationale: The correct answer is Hypercalcemia. In this case, the patient's history of myeloma, constipation, intense abdominal pain, and polyuria suggests hypercalcemia. Elevated calcium levels can lead to polyuria, severe abdominal pain, and confusion. Diverticulosis (Choice A), characterized by small pouches in the colon wall, typically does not present with confusion and polyuria. Hypocalcemia (Choice C) is unlikely given the symptoms described. Irritable bowel syndrome (Choice D) does not typically cause confusion and polyuria as seen in hypercalcemia.
