Nursing Elites

1. A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?

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

Correct answer: B

Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.

2. The nurse determines that an adult client who is admitted to the post-anesthesia care unit (PACU) following abdominal surgery has a tympanic temperature of 94.6°F (34.4°C), a pulse rate of 88 beats/minute, a respiratory rate of 14 breaths/minute, and a blood pressure of 94/68 mmHg. Which action should the nurse implement?

• A. Check the BP every five minutes for one hour.
• B. Raise the HOB 60 to 90 degrees.
• C. Ask the client to cough and deep breathe.
• D. Take the client’s temperature using another method.

Correct answer: D

Rationale: Taking the temperature using another method is essential in this situation to verify if the low reading is accurate and requires further intervention. The tympanic temperature of 94.6°F may be inaccurate due to various factors such as improper technique or environmental conditions. Checking the blood pressure every five minutes for one hour (Choice A) is not the priority in this case as the low blood pressure reading alone does not necessitate such frequent monitoring. Raising the head of the bed 60 to 90 degrees (Choice B) is not directly related to addressing the low temperature and blood pressure. Asking the client to cough and deep breathe (Choice C) is a general intervention that may not directly address the specific concern of the low temperature reading.

3. What is the main characteristic of cystic fibrosis?

• A. Multiple upper respiratory infections
• B. An underproduction of exocrine glands
• C. Excessive, thick mucus
• D. An overproduction of thin mucus

Correct answer: C

Rationale: The main characteristic of cystic fibrosis is the production of excessive, thick mucus. This thick mucus leads to blockages in the airways, digestive system, and other organs. Choice A is incorrect because while individuals with cystic fibrosis are more prone to respiratory infections, the main characteristic is the mucus production. Choice B is incorrect as cystic fibrosis is characterized by the overproduction, not underproduction, of exocrine glands. Choice D is also incorrect as the mucus produced in cystic fibrosis is thick, not thin.

4. What is the best position for a client experiencing a nosebleed?

• A. Sitting up and leaning forward
• B. Lying flat with a pillow under the head
• C. Sitting up and leaning back
• D. Lying on the side with the head elevated

Correct answer: A

Rationale: The best position for a client experiencing a nosebleed is sitting up and leaning forward. This position helps prevent blood from flowing down the throat and reduces the risk of aspiration. Choice B is incorrect as lying flat can lead to blood flowing down the throat. Choice C is also incorrect because leaning back may cause blood to flow backward into the throat. Choice D is incorrect as lying on the side with the head elevated is not the optimal position to manage a nosebleed effectively.

5. While walking to the mailbox, an older adult male experiences sudden chest tightness and drives himself to the emergency department. When the client gets up to the desk of the triage nurse, he says his heart is pounding out of his chest as he clutches his chest and falls to the floor. Which intervention should the nurse implement first?

• A. Prepare for cardiac defibrillation.
• B. Apply cardiac monitor leads.
• C. Obtain troponin serum levels.
• D. Palpate the client’s artery.

Correct answer: D

Rationale: Palpating the client's artery is the priority intervention in this scenario because it helps determine if there is a pulse, which is crucial information in emergency situations like this. If the client is pulseless, immediate initiation of CPR is necessary. Applying cardiac monitor leads or obtaining troponin serum levels can wait until the presence of a pulse is confirmed. Cardiac defibrillation is not indicated without first assessing the client's pulse and cardiac rhythm.
