Question

A nurse is reinforcing teaching with a client who is pregnant and has been prescribed isotretinoin for refractory nodular acne. The client expresses concern about potential side effects to their fetus. Which of the following responses by the nurse accurately addresses the client's concern and aligns with safe medication practices?

Answer 1

Correct Answers:

isotretinoin is contraindicated during pregnancy. You should stop the medication immediately and discuss alternative treatments with your health care provider.

Rationale :

🟦 Isotretinoin is a potent teratogen that causes severe congenital malformations, including craniofacial, cardiac, and central nervous system defects.

🟦 Fetal exposure is associated with a very high risk of spontaneous abortion and irreversible birth defects.

🟦 Due to these risks, isotretinoin is absolutely contraindicated during pregnancy and strictly regulated under iPLEDGE.

🟦 If pregnancy is suspected or confirmed, the medication must be discontinued immediately to prevent continued fetal exposure.

🟦 The nurse’s response should emphasize medication safety, provider notification, and discussion of safer alternative acne therapies.

“As long as you avoid vitamin A supplements, isotretinoin is safe to use during pregnancy.”

🟦 Isotretinoin itself is a vitamin A derivative and independently causes fetal toxicity.

🟦 Avoiding additional vitamin A does not reduce or eliminate teratogenic risk.

“You can safely continue isotretinoin during pregnancy as long as you use a reliable moisturizer for any dryness.”

🟦 Moisturizers only manage cutaneous dryness and do not affect fetal exposure.

🟦 Supportive skin care cannot make an unsafe medication safe in pregnancy.

“Joint pain is a common side effect of isotretinoin, but it does not pose any risks during pregnancy.”

🟦 This statement overlooks the primary danger of teratogenicity.

🟦 Musculoskeletal side effects are minor compared to the severe fetal risks.

Answer 2

Correct Answers:

Managing fluid resuscitation to prevent shock.

Rationale :

🟦 In the first 24 hours after a major burn, the greatest threat to life is hypovolemic shock caused by massive fluid shifts and capillary leakage.

🟦 Burns involving more than 20–25% total body surface area lead to rapid loss of intravascular volume into interstitial spaces.

🟦 Aggressive fluid resuscitation (commonly guided by the Parkland formula) is essential to maintain adequate tissue perfusion and organ function.

🟦 Urine output, vital signs, and hemodynamic status are closely monitored to evaluate the effectiveness of resuscitation.

🟦 Stabilizing circulation is the highest priority in the emergent phase, before wound care, nutrition, or infection prevention.

Performing debridement of burn wounds.

🟦 Debridement is important for wound healing but is not the immediate priority in the first 24 hours.

🟦 It is typically performed after the client is hemodynamically stable.

Providing nutritional support to aid healing.

🟦 Nutritional support is essential due to the hypermetabolic state caused by burns.

🟦 However, it becomes a priority after initial fluid resuscitation and stabilization.

Administering broad-spectrum antibiotics.

🟦 Prophylactic antibiotics are not routinely given in the immediate burn phase.

🟦 Infection prevention focuses first on aseptic technique and wound care, not early antibiotics.

Answer 3

Correct Answers:

Tretinoin

Rationale :

🟩 Tretinoin is a topical retinoid that promotes keratolytic activity by increasing epidermal cell turnover.

🟩 It works by loosening keratinocyte cohesion, allowing excess dead skin cells to shed more effectively.

🟩 This action helps unclog hair follicles, preventing formation of comedones in acne vulgaris.

🟩 Tretinoin also supports normalization of follicular epithelial desquamation, a key process in acne management.

🟩 Because of these effects, it is commonly prescribed as a first-line topical therapy for acne.

Hydrocortisone

🟩 Hydrocortisone is a topical corticosteroid used to reduce inflammation and itching.

🟩 It does not promote exfoliation or removal of excess skin cells.

Azithromycin

🟩 Azithromycin is a macrolide antibiotic that reduces acne by decreasing bacterial load.

🟩 It has no effect on keratinocyte turnover or exfoliation.

Loratadine

🟩 Loratadine is an antihistamine used to treat allergic symptoms.

🟩 It does not act on skin cell turnover or follicular keratinization.

Answer 4

Correct Answers:

"I can apply butter or oil to the burn to help soothe the skin."

Rationale :

🟧 Applying butter or oil to a burn is unsafe because these substances trap heat in the skin and can worsen tissue damage.

🟧 Oils create an occlusive barrier that prevents heat dissipation during the acute burn phase.

🟧 This practice also increases the risk of bacterial contamination and infection.

🟧 Evidence-based first aid emphasizes cooling the burn, not sealing heat into the tissue.

🟧 The nurse should correct this misconception to promote safe burn management and healing.

“I will avoid popping any blisters because it increases the risk of infection.”

🟧 Intact blisters act as a natural protective barrier against pathogens.

🟧 Breaking blisters exposes underlying tissue and increases infection risk.

“I will run cool water over the burn to stop the burning process.”

🟧 Cool running water helps halt thermal injury progression.

🟧 Ice or very cold water should be avoided, but cool water is appropriate.

“I should cover the burn with a clean, dry dressing after cooling it.”

🟧 A clean, dry dressing protects the area from contamination and friction.

🟧 Covering the burn also helps reduce pain and environmental exposure.

Answer 5

Correct Answers:

Stage I pressure injury

Rationale :

🟪 Stage I pressure injury is identified by non-blanchable erythema of intact skin, commonly over bony prominences such as the heels.

🟪 The skin remains intact, but redness does not fade when pressure is applied, indicating early tissue damage.

🟪 This stage reflects impaired capillary blood flow caused by sustained pressure in an immobile client.

🟪 Early recognition at this stage allows for prompt pressure relief and repositioning to prevent progression.

🟪 Identifying Stage I injuries is critical because they are reversible with timely nursing interventions.

Stage IV pressure injury

🟪 Stage IV involves full-thickness skin and tissue loss with exposed muscle, tendon, or bone.

🟪 Non-blanchable erythema alone does not meet criteria for this advanced stage.

Stage II pressure injury

🟪 Stage II presents with partial-thickness skin loss, such as an open blister or shallow ulcer.

🟪 Intact skin with redness indicates an earlier stage.

Stage III pressure injury

🟪 Stage III involves full-thickness skin loss without exposed bone or muscle.

🟪 Visible tissue loss must be present, which is not seen with simple erythema.

Answer 6

Correct Answers:

A sunburn

Rationale :

🟨 A first-degree burn involves only the epidermis, the outermost layer of the skin.

🟨 Sunburn is the classic example and presents with erythema, mild swelling, and pain without blistering.

🟨 The skin remains intact, and there is no damage to deeper tissue layers.

🟨 Healing typically occurs within a few days and does not result in scarring.

🟨 Recognizing first-degree burns helps guide appropriate first-aid care and prevention education.

Blackened dead skin

🟨 Blackened or charred skin indicates full-thickness tissue destruction.

🟨 This finding is associated with severe burns, not first-degree injuries.

Excessive scarring

🟨 Scarring occurs when deeper layers of skin are damaged.

🟨 First-degree burns heal without permanent skin changes.

Blistering from flames

🟨 Blistering reflects partial-thickness skin injury.

🟨 This presentation is consistent with second-degree burns, not first-degree burns.

Answer 7

Correct Answers:

18% for the trunk and 9% for the arm, totaling 27

Rationale :

🟫 The Rule of Nines is used to estimate total body surface area (TBSA) burned in adults.

🟫 The anterior trunk accounts for 18% of TBSA.

🟫 One entire arm (anterior and posterior) accounts for 9% of TBSA.

🟫 Adding these areas together results in a total burn area of 27% TBSA.

🟫 Accurate TBSA calculation is essential for guiding fluid resuscitation, burn severity classification, and treatment decisions.

9% for the trunk and 4.5% for the arm, totaling 13.5%.

🟫 The trunk is underestimated, as only the anterior or posterior half alone is 18%, not 9%.

🟫 An entire arm is 9%, not 4.5%.

18% for the trunk and 18% for the arm, totaling 36%.

🟫 An arm does not equal the trunk in TBSA percentage.

🟫 Assigning 18% to one arm overestimates burn size.

9% for the trunk and 9% for the arm, totaling 18%.

🟫 This calculation incorrectly assigns half the correct value to the trunk.

🟫 It significantly underestimates the true TBSA involved.

Answer 9

Correct Answers:

"This cream will help soften and remove the thick scales on my plaques."

Rationale :

🟩 Salicylic acid is a keratolytic agent that helps break down keratin and loosen adherent scales in psoriasis.

🟩 By promoting desquamation, it softens and removes thickened plaques, improving skin texture.

🟩 This action enhances penetration of other topical therapies, making overall treatment more effective.

🟩 Keratolytics target the hyperproliferation of skin cells, a hallmark of psoriasis.

🟩 The medication manages symptoms and improves comfort, though it does not eliminate the underlying disease.

“I should apply this medication over my entire body to prevent new plaques from forming.”

🟩 Keratolytic creams are intended for localized plaques, not widespread prophylactic use.

🟩 Applying over large areas increases the risk of skin irritation and systemic absorption.

“This medication will cure my psoriasis completely.”

🟩 Psoriasis is a chronic autoimmune condition without a definitive cure.

🟩 Salicylic acid provides symptom control, not disease eradication.

“This medication will suppress my immune system to stop the flare-up.”

🟩 Salicylic acid does not have immunosuppressive effects.

🟩 Its benefit comes from exfoliation, not immune modulation.

Answer 10

Correct Answers:

Pustule

Rationale :

🟦 Acne commonly presents as pustules, which are circumscribed, elevated lesions filled with purulent material.

🟦 These lesions form when hair follicles become clogged with sebum and keratin, followed by bacterial proliferation.

🟦 The presence of visible pus distinguishes pustules from non-infectious lesions.

🟦 Pustules are a hallmark of inflammatory acne, often surrounded by erythema.

🟦 Recognizing pustules guides appropriate topical or systemic antimicrobial and anti-inflammatory therapy.

Macule

🟦 A macule is a flat, non-palpable change in skin color.

🟦 It contains no fluid or pus, which does not match typical acne lesions.

Bulla

🟦 A bulla is a large, fluid-filled blister greater than 1 cm.

🟦 Bullae are seen in burns or blistering disorders, not acne.

Nodule

🟦 A nodule is a solid, deep lesion extending into the dermis or subcutaneous tissue.

🟦 While nodular acne exists, the general lesion type associated with acne is pustular.
