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 healthcare professional is taking the health history of a patient being treated for sickle cell disease. After being told the patient has severe generalized pain, the healthcare professional expects to note which assessment finding?

• A. Severe and persistent diarrhea
• B. Intense pain in the toe
• C. Yellow-tinged sclera
• D. Headache

Correct answer: C

Rationale: In patients with sickle cell disease, severe generalized pain can be associated with vaso-occlusive crises, but yellow-tinged sclera is a common clinical finding related to sickle cell disease. This yellowing of the sclera, known as jaundice, occurs due to the release of bilirubin from damaged or destroyed red blood cells. Severe and persistent diarrhea is not a typical assessment finding in sickle cell disease. Intense pain in the toe may be associated with vaso-occlusive crisis but is not the expected assessment finding in this scenario. Headache is a common symptom in many conditions but is not specifically related to the assessment finding expected in a patient with sickle cell disease presenting with severe generalized pain.

3. A 1-year-old child is diagnosed with intussusception, and the mother of the child asks the student nurse to describe the disorder. Which statement by the student nurse indicates correct understanding of this disorder?

• A. It is an acute bowel obstruction.
• B. It is a condition that causes an acute inflammatory process in the bowel.
• C. It is a condition in which a distal segment of the bowel prolapses into a proximal segment of the bowel.
• D. It is a condition in which a proximal segment of the bowel prolapses into a distal segment of the bowel.

Correct answer: D

Rationale: Intussusception is a condition in which a proximal segment of the bowel telescopes or prolapses into a distal segment of the bowel. This leads to bowel obstruction and potential ischemia. It is not an acute bowel obstruction, as the obstruction is caused by the telescoping of bowel segments rather than a blockage in the bowel lumen. Intussusception is not primarily an inflammatory process; instead, it is a mechanical issue involving bowel invagination. Choice A is incorrect as it does not accurately describe the pathophysiology of intussusception. Choice C is incorrect because it presents the opposite scenario of what happens in intussusception.

4. Which of the following patients is at the greatest risk for a stroke?

• A. A 60-year-old male who weighs 270 pounds, has atrial fibrillation, and has had a TIA in the past
• B. A 75-year-old male who has frequent migraines, drinks a glass of wine every day, and is Hispanic
• C. A 40-year-old female who has high cholesterol and uses oral contraceptives
• D. A 65-year-old female who is African American, has sickle cell disease, and smokes cigarettes

Correct answer: A

Rationale: The correct answer is the 60-year-old male who has a combination of significant risk factors for stroke, including atrial fibrillation, a history of a transient ischemic attack (TIA), and obesity. These factors greatly increase his risk of stroke. While other choices may have some individual risk factors, they do not collectively pose as high a risk as the patient described in option A. Option B includes migraines and alcohol consumption but lacks other major risk factors seen in option A. Option C mentions high cholesterol and oral contraceptives, which are risk factors but not as significant as atrial fibrillation and a prior TIA. Option D includes smoking and sickle cell disease but lacks the crucial risk factors present in option A.

5. After performing an assessment of an infant with bladder exstrophy, the nurse prepares a plan of care. The nurse identifies which problem as the priority for the infant?

• A. Urinary incontinence
• B. Impaired tissue integrity
• C. Inability to suck and swallow
• D. Lack of knowledge about the disease (parents)

Correct answer: B

Rationale: In bladder exstrophy, the bladder is exposed and external to the body, leading to impaired tissue integrity related to the exposed bladder mucosa as the priority problem. Urinary incontinence is not a concern as the infant is not yet toilet trained. Inability to suck and swallow is unrelated to the disorder. While educating the parents about the condition is important, it is not the priority over addressing the immediate risk of impaired tissue integrity in the infant.
