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. The nurse is planning care for a client during the acute phase of a sickle cell vasoocclusive crisis. Which of the following actions would be most appropriate?

• A. Fluid restriction to 1000cc per day
• B. Ambulate in the hallway 4 times a day
• C. Administer analgesic therapy as ordered
• D. Encourage increased caloric intake

Correct answer: C

Rationale: Administering analgesic therapy as ordered is the most appropriate action during the acute phase of a sickle cell vasoocclusive crisis. In this phase, the primary focus is on managing the severe pain experienced by the individual. Analgesic therapy helps alleviate the pain and discomfort associated with the crisis. The other options are not the priority during this phase. Fluid restriction is not recommended as hydration is crucial in managing a vasoocclusive crisis. Ambulation may worsen the pain and should be minimized during this phase. Encouraging increased caloric intake is not directly related to managing the acute phase of a vasoocclusive crisis.

3. A mother brings her 5-week-old infant to the health care clinic and tells the nurse that the child has been vomiting after meals. The mother reports that the vomiting is becoming more frequent and forceful. The nurse suspects pyloric stenosis and asks the mother which assessment question to elicit data specific to this condition?

• A. Are the stools ribbon-like, and is the infant eating poorly?
• B. Does the infant suddenly become pale, begin to cry, and draw the legs up to the chest?
• C. Does the vomit contain sour, undigested food without bile, and is the infant constipated?
• D. Does the infant cry loudly and continuously during the evening hours but nurses or takes formula well?

Correct answer: C

Rationale: Vomiting undigested food that is not bile stained and constipation are classic symptoms of pyloric stenosis. Stools that are ribbon-like and a child who is eating poorly are signs of congenital megacolon (Hirschsprung's disease). An infant who suddenly becomes pale, cries out, and draws the legs up to the chest is demonstrating physical signs of intussusception. Crying during the evening hours, appearing to be in pain, eating well, and gaining weight are clinical manifestations of colic.

4. When asked to describe in layman's terms an overview of the condition called osteomyelitis, what would be the nurse's best response?

• A. Osteomyelitis is a gradual breakdown and weakening of your bones. It's most often age-related.
• B. Osteomyelitis is caused by not having enough Vitamin D, which in turn causes your bones to be softer and demineralized.
• C. Osteomyelitis is an infection in the bone. It can be caused by bacteria reaching your bone from outside or inside your body.
• D. This is a question that should be directed to your healthcare provider.

Correct answer: C

Rationale: Osteomyelitis is an infection in the bone that can be caused by bacteria reaching the bone either from outside the body (such as through an open fracture) or inside the body (such as through the bloodstream). This response provides a concise and accurate explanation of osteomyelitis, making it the best choice. Choices A and B provide inaccurate information about the condition, attributing it to age-related bone breakdown and Vitamin D deficiency, which are not correct causes of osteomyelitis. Choice D deflects the question instead of providing the patient with a clear explanation, making it an inappropriate response.

5. A client is found unresponsive in his room by a nurse. The client is not breathing and does not have a pulse. After calling for help, what is the next action the nurse should take?

• A. Administer 2 ventilations
• B. Perform a head-tilt, chin lift to open the airway
• C. Begin chest compressions
• D. Perform a jaw thrust to open the airway

Correct answer: C

Rationale: After finding an unresponsive client who is not breathing and has no pulse, the nurse's immediate action should be to call for help and start chest compressions. Chest compressions should be initiated at a rate of at least 100 per minute and a depth of at least 2 inches. Choice A, administering ventilations, is not the initial step as compressions take priority. Choice B, performing a head-tilt, chin lift, is also not the first step; chest compressions are crucial before airway management. Choice D, performing a jaw thrust, is typically used in cases of suspected cervical spine injury and is not the immediate action in this scenario.
