Nursing Elites

1. What is an important nursing responsibility when a dysrhythmia is suspected?

• A. order an immediate electrocardiogram
• B. count the radial pulse every 1 minute for five times
• C. count the apical pulse for 1 full minute, and compare the rate with the radial pulse rate
• D. have someone else take the radial pulse simultaneously with the apical pulse

Correct answer: C

Rationale: When a dysrhythmia is suspected, an important nursing responsibility is to count the apical pulse for 1 full minute and then compare this rate with the radial pulse rate. This method helps in identifying dysrhythmias as it allows for a direct comparison of the heart's rhythm at two different pulse points. Ordering an immediate electrocardiogram (Choice A) may be necessary but should not be the first step. Counting the radial pulse multiple times (Choice B) is not as accurate as comparing rates directly. Having someone else take the radial pulse simultaneously (Choice D) may introduce errors and inconsistencies in the measurement.

2. A 15-month-old child with the diagnosis of hydrocephalus is scheduled for a computed tomography (CT) scan. What should the nurse include when preparing the toddler for the CT scan?

• A. Shaving the head
• B. Starting the prescribed IV infusion
• C. Administering the prescribed sedative
• D. Giving the child a simple explanation of the procedure

Correct answer: D

Rationale: Preparing a toddler for a CT scan involves providing a simple explanation of the procedure to reduce anxiety and help the child understand what will happen. This approach helps establish trust and cooperation, making the experience less frightening for the child. Shaving the head, starting an IV infusion, or administering a sedative are not typically part of the preparation for a CT scan in a toddler and may not be necessary or appropriate in this scenario.

3. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:

• A. nondisjunction.
• B. X-linked recessive inheritance.
• C. genomic imprinting.
• D. autosomal dominant inheritance.

Correct answer: A

Rationale: Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division that leads to the presence of an extra chromosome 21. This additional chromosome alters the normal genetic makeup, resulting in the characteristics associated with Down syndrome. Therefore, the correct answer is nondisjunction (Choice A). Choices B, C, and D are incorrect because Trisomy 21 is not caused by X-linked recessive inheritance, genomic imprinting, or autosomal dominant inheritance. Understanding the specific genetic mechanism involved in Trisomy 21 is crucial for grasping the basis of this chromosomal disorder.

4. A healthcare professional is educating a parent group about the importance of immunizations. Which disease can be prevented by the varicella vaccine?

• A. Measles
• B. Mumps
• C. Rubella
• D. Chickenpox

Correct answer: D

Rationale: The varicella vaccine is specifically designed to prevent chickenpox. Measles, mumps, and rubella are prevented by different vaccines (MMR vaccine for measles, mumps, and rubella). Therefore, the correct answer is chickenpox (varicella). It is crucial for healthcare professionals to provide accurate information about vaccines to help ensure the health and well-being of individuals.

5. A child with a diagnosis of celiac disease is being discharged. What dietary instructions should the nurse provide?

• A. Avoid dairy products
• B. Avoid gluten
• C. Avoid high-fat foods
• D. Avoid foods high in sugar

Correct answer: B

Rationale: The correct answer is to 'Avoid gluten.' Celiac disease is an autoimmune disorder triggered by gluten consumption, a protein found in wheat, barley, and rye. By avoiding gluten-containing foods, individuals with celiac disease can prevent damage to their small intestine and manage their symptoms effectively. Choice A, 'Avoid dairy products,' is incorrect as dairy is not directly related to celiac disease. Choice C, 'Avoid high-fat foods,' and Choice D, 'Avoid foods high in sugar,' are incorrect as they are not primary dietary concerns in managing celiac disease. The main focus should be on eliminating gluten sources from the diet.
