1. The mother of a child who weighs 45 lb asks a nurse about car safety seats. The nurse tells the mother to place the child in which car safety seat?

A. Car safety seat in the back seat in a face-forward position
B. Booster seat with one of the car's seat belts placed over the child
C. Booster seat in a rear-facing position in the front seat
D. Car safety seat in a face-forward position in the front seat

Correct answer: B

Rationale: The correct answer is to place the child in a booster seat with one of the car's seat belts placed over the child. A child needs to remain in a car safety seat until he or she weighs 40 lb. Once the child has outgrown the car safety seat, a booster seat is used. Booster seats are designed to raise the child high enough so that the restraining straps are correctly positioned over the child's chest and pelvis, providing optimal safety. Placing a child in a booster seat in a rear-facing position in the front seat is incorrect as children should not be seated in the front seat due to potential airbag-related injuries. Additionally, car safety seats are used for children weighing less than 40 lb and are placed in the middle of the back seat in a rear-facing position for maximum protection.

2. The LPN is checking for residual before administering enteral feeding through a PEG tube. Which of these steps is incorrect?

A. The LPN elevates the head of the bed by at least 30 degrees.
B. If the residual is greater than 200mL, the LPN should not administer the enteral feeding.
C. The LPN should discard the residual before administering the tube feeding.
D. The residual pH level is tested to ensure appropriate placement.

Correct answer: C

Rationale: The incorrect step is choice C. The residual should be discarded before administering the tube feeding. Discarding the residual is essential to prevent contamination and ensure accurate measurement of the enteral feeding. Elevating the head of the bed by at least 30 degrees (choice A) is correct as it helps prevent aspiration during feeding. Testing the pH level of the residual (choice D) ensures proper placement of the tube. Withholding feeding if the residual is greater than 200mL (choice B) is crucial to prevent overfeeding, making this statement correct.

3. Which of the following nursing diagnoses is most appropriate for a client with a new colostomy?

A. Excess Fluid Volume
B. Risk for Aspiration
C. Disturbed Body Image
D. Urinary Retention

Correct answer: C

Rationale: Disturbed Body Image is the most appropriate nursing diagnosis for a client with a new colostomy. A new colostomy can significantly impact a person's body image and self-esteem due to the physical changes it brings. This can lead to emotional distress, adjustment issues, and concerns about body image. Excess Fluid Volume, Risk for Aspiration, and Urinary Retention are not directly related to the psychosocial impact of a new colostomy and are therefore not as relevant in this context. While Excess Fluid Volume, Risk for Aspiration, and Urinary Retention are important nursing diagnoses, they are not the priority when considering the psychological and emotional effects of a new colostomy.

4. What is a predisposing factor for cancer of the tongue?

A. tobacco use
B. obesity
C. sun exposure
D. eating sweets

Correct answer: A

Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.

5. Which is the proper hand position for performing chest vibration?

A. cup the hands
B. use the side of the hands
C. flatten the hands
D. spread the fingers of both hands

Correct answer: C

Rationale: The correct hand position for performing chest vibration is to flatten the hands. By flattening the hands over the area of the body where chest percussion is applied, vibrations can be conducted effectively to the chest to help loosen secretions. Cupping the hands may dampen vibrations, using the side of the hands reduces the surface area in contact with the chest, and spreading the fingers can lead to uneven pressure distribution. Therefore, flattening the hands provides the necessary contact and surface area to perform chest vibration efficiently.
