Nursing Elites

1. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?

• A. The bicarbonate level (HCO3) is 31 mEq/L
• B. The arterial oxygen saturation (SaO2) is 92%
• C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
• D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg

Correct answer: D

Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.

2. Mr. L was working in his garage at home and had an accident with a power saw. He is brought into the emergency department by a neighbor with a traumatic hand amputation. What is the first action of the nurse?

• A. Place a tourniquet at the level of the elbow
• B. Apply direct pressure to the injury
• C. Administer a bolus of 0.9% Normal Saline
• D. Elevate the injured extremity on a pillow

Correct answer: B

Rationale: The correct first action for the nurse in this scenario is to apply direct pressure to the injury. When a client presents with traumatic hand amputation causing excessive bleeding, the immediate goal is to control the bleeding. Applying direct pressure with a sterile dressing helps to stem the flow of blood and stabilize the patient. Placing a tourniquet at the level of the elbow should be avoided initially as it may lead to further complications such as tissue damage. Administering a bolus of 0.9% Normal Saline is not the priority in this situation where hemorrhage control is crucial. Elevating the injured extremity on a pillow does not address the primary concern of controlling the bleeding and stabilizing the patient.

3. A client presents with symptoms of a sore throat, swollen lymph nodes in the neck, fever, chills, and extreme fatigue. Based on these symptoms, which of the following illnesses could the nurse consider for this client?

• A. Methicillin-resistant Staphylococcus aureus (MRSA)
• B. Hepatitis B
• C. Infectious mononucleosis
• D. Norovirus infection

Correct answer: C

Rationale: Infectious mononucleosis is a viral disease caused by the Epstein-Barr virus. The symptoms of sore throat, fever, chills, swollen lymph nodes, and extreme fatigue are characteristic of infectious mononucleosis. The diagnosis is confirmed through the client's history and blood tests for the Epstein-Barr virus. Methicillin-resistant Staphylococcus aureus (MRSA) presents with localized skin infections, not the systemic symptoms described. Hepatitis B typically presents with jaundice, abdominal pain, and liver inflammation, not the symptoms described. Norovirus infection commonly causes gastrointestinal symptoms like vomiting and diarrhea, not the symptoms presented by the client.

4. The healthcare provider is reviewing the lab results of a patient who has presented in the Emergency Room. The lab results show that the troponin T value is at 5.3 ng/mL. Which of these interventions, if not already completed, would take priority over the others?

• A. Place the patient in a 90-degree position
• B. Assess whether the patient is taking diuretics
• C. Obtain and attach defibrillator leads
• D. Assess the patient's last ejection fraction

Correct answer: C

Rationale: In this scenario, the elevated Troponin T level indicates cardiac damage, possibly due to a myocardial infarction. A Troponin T value of 5.3 ng/mL is significantly elevated (normal levels are below 0.2 ng/mL), suggesting acute cardiac injury. Given the setting of an Emergency Room and the critical nature of the situation, the priority intervention should be to obtain and attach defibrillator leads. Elevated Troponin T levels can indicate a higher risk of arrhythmias, including ventricular fibrillation, which can lead to sudden cardiac arrest. Defibrillator leads are essential for monitoring the patient's cardiac rhythm and readiness for immediate defibrillation if necessary. Placing the patient in a 90-degree position (Choice A) or assessing diuretic use (Choice B) are not immediate priorities in this critical situation. Additionally, assessing the patient's last ejection fraction (Choice D) is important but not as urgent as preparing for potential life-threatening arrhythmias requiring defibrillation.

5. When assessing a child admitted to the hospital with pyloric stenosis, which symptom would the nurse likely find when asking the parent about the child's symptoms?

• A. Watery diarrhea
• B. Projectile vomiting
• C. Increased urine output
• D. Vomiting large amounts of bile

Correct answer: B

Rationale: In pyloric stenosis, hypertrophy of the circular muscles of the pylorus causes narrowing of the pyloric canal between the stomach and the duodenum. The hallmark symptom of pyloric stenosis is projectile vomiting, which is the forceful expulsion of stomach contents. Other common symptoms include irritability, hunger and crying, constipation, and signs of dehydration. Watery diarrhea (Choice A) is not a typical symptom of pyloric stenosis. Increased urine output (Choice C) is not directly associated with this condition. Vomiting large amounts of bile (Choice D) is not a characteristic symptom of pyloric stenosis; instead, the vomitus in pyloric stenosis is non-bilious.
