1. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

2. A patient has come into the emergency room after an injury at work in which their upper body was pinned between two pieces of equipment. The nurse notes bruising in the upper abdomen and chest. The patient is complaining of sharp chest pain, having difficulty breathing, and their trachea is deviated to the left side. Which of the following conditions are these symptoms most closely associated with?

• A. Left-sided pneumothorax
• B. Pleural effusion
• C. Atelectasis
• D. Right-sided pneumothorax

Correct answer: D

Rationale: The patient is most likely suffering from a right-sided pneumothorax. Symptoms of a pneumothorax include sharp chest pain, difficulties with breathing, decreased vocal fremitus, absent breath sounds, and tracheal shift to the opposite of the affected side. In this case, the patient's trachea is deviated to the left side, indicating a right-sided pneumothorax. Choices A, B, and C can be eliminated as they do not present with the specific symptoms described in the scenario. Left-sided pneumothorax would not cause tracheal deviation to the left side. Pleural effusion typically presents with dull chest pain and decreased breath sounds, not sharp chest pain and tracheal deviation. Atelectasis would not cause tracheal deviation and is more associated with lung collapse rather than air accumulation in the pleural space.

3. While eating in the hospital cafeteria, a nurse notices a toddler at a nearby table choking on a piece of food and appearing slightly blue. What is the appropriate initial action to take?

• A. Begin mouth-to-mouth resuscitation
• B. Give the child water to help with swallowing
• C. Perform 5 abdominal thrusts
• D. Call for the emergency response team

Correct answer: C

Rationale: When a toddler is choking on a piece of food and appears blue, it indicates airway obstruction. The appropriate initial action should be to perform 5 abdominal thrusts. This technique can help dislodge the obstructing object and clear the airway. Initiating mouth-to-mouth resuscitation is not recommended as the first step in a choking emergency, especially in children. Giving water may not be effective and can worsen the situation by causing further blockage. Calling the emergency response team should be considered if the abdominal thrusts are unsuccessful in clearing the airway.

4. When analyzing the results of the urinalysis collected preoperatively from a child with epispadias scheduled for surgical repair, which finding should the nurse most likely expect to note?

• A. Hematuria
• B. Proteinuria
• C. Bacteriuria
• D. Glucosuria

Correct answer: C

Rationale: Epispadias is a congenital defect characterized by the abnormal placement of the urethral orifice of the penis, often on the dorsum. This anatomical anomaly predisposes individuals to bacterial entry into the urinary tract, leading to bacteriuria. Hematuria, proteinuria, and glucosuria are not typically associated with epispadias. Hematuria refers to the presence of blood in the urine, proteinuria indicates protein in the urine, and glucosuria is the presence of glucose in the urine, none of which are commonly seen in epispadias.

5. The healthcare professional in the Emergency Room is treating a patient suspected to have a Peptic Ulcer. On assessing lab results, the healthcare professional finds that the patient's blood pressure is 95/60, pulse is 110 beats per minute, and the patient reports epigastric pain. What is the PRIORITY intervention?

• A. Start a large-bore IV in the patient's arm
• B. Ask the patient for a stool sample
• C. Prepare to insert an NG Tube
• D. Administer intramuscular morphine sulfate as ordered

Correct answer: A

Rationale: The priority intervention in this scenario is to start a large-bore IV in the patient's arm. The patient's low blood pressure (95/60) and elevated pulse rate (110 beats per minute) indicate a potential hemorrhage, requiring immediate fluid resuscitation. Starting a large-bore IV will allow for rapid administration of fluids to stabilize the patient's condition. Asking for a stool sample, preparing to insert an NG tube, or administering morphine sulfate should not take precedence over addressing the hemodynamic instability and potential hemorrhage observed in the patient. These actions may be considered later in the patient's care, but the primary focus should be on addressing the critical issue of fluid replacement and stabilization.
