Nursing Elites

1. A group of students is reviewing information about the various types of insulin used to treat type 1 diabetes. The students demonstrate understanding of the information when they identify which of these insulins as having the longest duration?

• A. Lispro
• B. Regular
• C. NPH
• D. Glargine

Correct answer: D

Rationale: The correct answer is Glargine (Lantus) as it has the longest duration of action among the insulins listed, lasting 12 to 24 hours. Lispro (A) and Regular (B) are rapid-acting insulins with shorter durations of action. NPH (C) is an intermediate-acting insulin with a duration of action of about 12-16 hours. Therefore, Glargine is the correct choice for the insulin with the longest duration.

2. The nurse is developing a plan of care for a 7-year-old boy with diabetes insipidus. What is the priority nursing diagnosis?

• A. Deficient fluid volume related to dehydration
• B. Excess fluid volume related to edema
• C. Deficient knowledge related to fluid intake regimen
• D. Imbalanced nutrition related to excess weight

Correct answer: A

Rationale: The priority nursing diagnosis for a 7-year-old boy with diabetes insipidus is deficient fluid volume related to dehydration. Diabetes insipidus causes excessive thirst and urination, leading to fluid imbalance and potential dehydration. Choice B, excess fluid volume related to edema, is not a priority as diabetes insipidus is characterized by fluid loss, not retention. Choice C, deficient knowledge related to fluid intake regimen, may be important but is not the priority when the child is at risk of dehydration. Choice D, imbalanced nutrition related to excess weight, is not directly associated with the primary concern of fluid volume imbalance in diabetes insipidus.

3. A healthcare professional is educating a group of parents on preventing childhood obesity. What should the professional recommend?

• A. Encourage high-calorie snacks
• B. Limit screen time
• C. Encourage fast food as a treat
• D. Allow the child to eat freely

Correct answer: B

Rationale: The correct answer is to limit screen time when preventing childhood obesity. Excessive screen time is associated with a sedentary lifestyle and can lead to increased consumption of unhealthy foods. Encouraging high-calorie snacks (choice A) contradicts the goal of preventing obesity. While fast food as an occasional treat (choice C) can be acceptable in moderation, it should not be encouraged as a preventive measure against obesity. Allowing the child to eat freely (choice D) without guidance can lead to overconsumption of unhealthy foods and contribute to obesity risk.

4. The parents of a child who is scheduled for open-heart surgery ask why their child must be subjected to chest tubes after surgery. What should the nurse consider before responding in language the parents will understand?

• A. They will increase tidal volumes.
• B. Drainage of air and fluid will be facilitated.
• C. They will maintain positive intrapleural pressure.
• D. Pressure on the pericardium and chest wall will be regulated.

Correct answer: B

Rationale: Chest tubes are used to drain air and fluid from the chest cavity to prevent complications such as pneumothorax or cardiac tamponade after surgery. Choice A is incorrect as chest tubes are not used to increase tidal volumes. Choice C is incorrect as chest tubes do not maintain positive intrapleural pressure; instead, they assist in removing excess air or fluid. Choice D is incorrect as chest tubes do not regulate pressure on the pericardium and chest wall; they primarily aid in drainage.

5. 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.
