Nursing Elites

1. 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.

2. 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.

3. A client is scheduled for an Intravenous Pyelogram (IVP). In order to prepare the client for this test, the nurse would:

• A. Instruct the client to maintain a regular diet the day prior to the examination
• B. Restrict the client's fluid intake 4 hours prior to the examination
• C. Administer a laxative to the client the evening before the examination
• D. Inform the client that only 1 x-ray of his abdomen is necessary

Correct answer: C

Rationale: Administering a laxative to the client the evening before the examination is the correct action. Bowel prep is crucial for an Intravenous Pyelogram (IVP) as it helps in achieving better visualization of the bladder and ureters. Instructing the client to maintain a regular diet the day prior to the examination (Choice A) is not the appropriate preparation for an IVP. Restricting the client's fluid intake 4 hours prior to the examination (Choice B) is not necessary for this test. Informing the client that only 1 x-ray of his abdomen is necessary (Choice D) is not relevant to the preparation process for an IVP.

4. The mother of a child who had a cleft palate repair 4 days ago is receiving home care instructions. Which statement by the mother indicates the need for further instruction?

• A. ''I will use a short nipple on the bottle.''
• B. ''I should avoid using straws for drinking.''
• C. ''I can give my child the pacifier in 2 weeks.''
• D. ''I may give my baby food mixed with water.''

Correct answer: B

Rationale: The correct answer is ''I should avoid using straws for drinking.'' After a cleft palate repair, the child should avoid straws, pacifiers, spoons, and fingers near the mouth for 7 to 10 days to prevent injury to the surgical site. Allowing the child to use a straw can create negative pressure in the mouth, potentially disrupting the healing process. The other options are appropriate postoperative instructions for a child who had a cleft palate repair and do not pose a risk to the surgical site.

5. When assessing a patient suspected to have Hepatitis, a nurse notes the patient's eyes are yellow-tinged. Which of the following diagnostic results would further assist in confirming this diagnosis?

• A. Decreased serum Bilirubin
• B. Elevated serum ALT levels
• C. Low RBC and Hemoglobin with increased WBCs
• D. Increased Blood Urea Nitrogen level

Correct answer: B

Rationale: Elevated serum ALT levels would further confirm the diagnosis of Hepatitis. ALT is a liver enzyme, and hepatitis is a liver disease. Elevated liver enzymes, such as ALT, often indicate liver damage. Choice A, 'Decreased serum Bilirubin,' is incorrect as elevated bilirubin levels are typically seen in hepatitis due to impaired bilirubin metabolism. Choices C and D are unrelated to confirming a diagnosis of hepatitis as they describe findings not specific to liver function or hepatitis. Low RBC and Hemoglobin with increased WBCs (Choice C) suggest a different condition like anemia or infection, not specific to liver disease. Increased Blood Urea Nitrogen level (Choice D) is more indicative of kidney function rather than liver function, thus not helpful in confirming hepatitis.
