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 3-year-old child is seen in the health care clinic, and a diagnosis of encopresis is made. The nurse expects to provide teaching about which client problem?

• A. Odor
• B. Nausea
• C. Malaise
• D. Diarrhea

Correct answer: A

Rationale: Encopresis is the repeated voluntary or involuntary passage of feces of normal or near-normal consistency in places not appropriate for that purpose according to the individual's own sociocultural setting. Signs of encopresis include evidence of soiled clothing, scratching or rubbing the anal area due to irritation, fecal odor without apparent awareness by the child, and social withdrawal. Teaching about odor is essential to address the issue of encopresis. Choices B, C, and D are incorrect because encopresis is not typically associated with nausea, malaise, or diarrhea. Therefore, teaching about these symptoms would not be relevant in the context of encopresis.

4. A child is diagnosed with Hirschsprung's disease. The nurse is teaching the parents about the cause of the disease. Which statement, if made by the parent, supports that teaching was successful?

• A. The absence of special cells in the rectum caused the disease.
• B. Incomplete digestion of the protein part of wheat, barley, rye, and oats is not the cause of the disease.
• C. The disease does not occur due to increased bowel motility leading to spasm and pain.
• D. The disease is not caused by the inability to tolerate sugar found in dairy products.

Correct answer: A

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or megacolon, is characterized by the absence of ganglion cells in the rectum and, sometimes, extending into the colon. Choice A correctly explains the cause of Hirschsprung's disease. Choice B is incorrect as it describes celiac disease, which is related to gluten intolerance. Choice C is inaccurate as it describes symptoms of irritable bowel syndrome, not the cause of Hirschsprung's disease. Choice D is wrong as it pertains to lactose intolerance, not Hirschsprung's disease.

5. The major difference between a grand mal and petit mal seizure is that a person with a grand mal seizure will have _______________ and the person with a petit mal seizure will not.

• A. convulsive movements
• B. sleep apnea
• C. atonic movements
• D. flaccidity

Correct answer: A

Rationale: The major difference between a grand mal and petit mal seizure is the presence or absence of convulsive movements. Grand mal seizures are characterized by convulsive movements, including jerking of limbs and loss of consciousness. In contrast, petit mal seizures, also known as absence seizures, typically involve brief episodes of staring or eye blinking without convulsive movements. Therefore, choice A, 'convulsive movements,' is the correct answer. Choices B, 'sleep apnea,' and D, 'flaccidity,' are incorrect as they are not associated with the characteristics of grand mal or petit mal seizures. Choice C, 'atonic movements,' is also incorrect as petit mal seizures do not involve atonic movements, but rather absence behaviors such as staring spells.
