1. Which observation of the exposed abdomen is most indicative of pyloric stenosis?

• A. abdominal rigidity
• B. substernal retraction
• C. palpable olive-like mass
• D. marked distention of the lower abdomen

Correct answer: C

Rationale: In pyloric stenosis, a palpable olive-like mass in the abdomen is a classic finding. This mass is due to the hypertrophied pyloric muscle. Abdominal rigidity (choice A) is associated with conditions like peritonitis, substernal retraction (choice B) is typically seen in respiratory distress, and marked distention of the lower abdomen (choice D) is more characteristic of conditions like intestinal obstruction rather than pyloric stenosis.

2. Which best describes a full-thickness (third-degree) burn?

• A. Erythema and pain
• B. Skin showing erythema followed by blister formation
• C. Destruction of all layers of skin evident with extension into subcutaneous tissue
• D. Destruction injury involving underlying structures such as muscle, fascia, and bone

Correct answer: C

Rationale: The correct answer is C: Full-thickness burns involve the destruction of all layers of skin, extending into the subcutaneous tissue. This type of burn causes severe damage and loss of sensation due to nerve destruction. Choice A, erythema and pain, describes superficial burns (first-degree). Choice B, skin showing erythema followed by blister formation, describes partial-thickness burns (second-degree). Choice D, destruction injury involving underlying structures such as muscle, fascia, and bone, goes beyond the description of full-thickness burns.

3. Which best describes a full-thickness (third-degree) burn?

• A. Erythema and pain
• B. Skin showing erythema followed by blister formation
• C. Destruction of all layers of skin evident with extension into subcutaneous tissue
• D. Destruction injury involving underlying structures such as muscle, fascia, and bone

Correct answer: C

Rationale: A full-thickness (third-degree) burn involves the destruction of all layers of skin, including the epidermis, dermis, and extending into the subcutaneous tissue. This type of burn results in significant tissue damage and can appear pale, charred, or leathery. Choice A is incorrect as erythema and pain are more characteristic of superficial burns. Choice B describes a partial-thickness burn where the skin shows erythema followed by blister formation, involving the epidermis and part of the dermis. Choice D is incorrect as it describes a deeper type of injury involving structures beyond the skin layers, such as muscle, fascia, and bone, which is not specific to a full-thickness burn.

4. A child is brought to the clinic after tripping over a rock. The child states, 'I twisted my ankle,' and is given a diagnosis of a sprain. What intervention is most important for the nurse to include in the discharge instructions for this child?

• A. For the first 24 hours, apply ice for 20 minutes and then remove for 60 minutes.
• B. Bed rest with the leg elevated for 36 hours.
• C. May take an NSAID for pain as needed.
• D. Use a compression dressing for 72 hours.

Correct answer: A

Rationale: The correct intervention for a sprained ankle is to apply ice for 20 minutes every hour for the first 24 hours, then remove for 60 minutes to prevent tissue damage. This regimen helps reduce swelling and pain. Bed rest with the leg elevated for an extended period (36 hours) may lead to stiffness and decreased range of motion. While NSAIDs can be used for pain, they may not be necessary if pain is manageable with ice and rest. Using a compression dressing for 72 hours continuously may impede proper circulation and delay healing by restricting blood flow.

5. A child is diagnosed with atopic dermatitis. Which laboratory test would the nurse expect the child to undergo to provide additional evidence for this condition?

• A. Erythrocyte sedimentation rate
• B. Potassium hydroxide prep
• C. Wound culture
• D. Serum immunoglobulin E (IgE) level

Correct answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.
