Correct Answer: A

Rationale: The correct answer is A: Butterfly rash on the face. A butterfly-shaped rash across the nose and cheeks is a classic symptom of systemic lupus erythematosus (SLE), an autoimmune disease. Weight gain (Choice B) is not typically associated with SLE. Joint deformities (Choice C) are more commonly seen in conditions like rheumatoid arthritis. Increased hair growth (Choice D) is not a typical finding in SLE.

Correct Answer: D

Rationale: The vastus lateralis is the preferred site for IM injections in infants under 1 year of age because it is well developed and easily accessible compared to other muscle groups. The ventrogluteal and deltoid sites are not typically used for infants due to muscle development and size. The dorsogluteal site is not recommended for infants or young children due to its proximity to major nerves and blood vessels.

Correct Answer: B

Rationale: The correct answer is B: Asymmetric with variegated coloring. An asymmetric lesion with variegated coloring, meaning different shades of color within the same lesion, is characteristic of melanoma, a type of skin cancer. This type of lesion should raise suspicions and prompt further evaluation. Choices A, C, and D do not typically represent characteristics of suspicious skin lesions associated with skin cancer. Lesions that are scaly and red (Choice A) may indicate other skin conditions like eczema or psoriasis. Firm and rubbery lesions (Choice C) are more suggestive of benign skin growths like dermatofibromas. Lesions that are brown with a wart-like texture (Choice D) are often indicative of seborrheic keratosis, a benign growth, rather than a suspicious lesion related to skin cancer.

Correct Answer: C

Rationale: The correct action the nurse should take when administering enoxaparin is to inject the medication in the abdomen subcutaneously. This route ensures proper absorption of the medication. Aspiration is not necessary before injecting enoxaparin as it is a subcutaneous injection, not an intramuscular injection. Massaging the site after injecting should be avoided to prevent bruising. Enoxaparin injections are typically given at a 45 to 90-degree angle, not necessarily at a strict 90-degree angle.

Correct Answer: B

Rationale: The correct answer is B. Rh-negative mothers who give birth to an Rh-positive baby should receive Rh immune globulin within 72 hours of delivery to prevent the development of antibodies in future pregnancies. Choice A is incorrect because Rh-negative individuals are the ones who require Rh immune globulin. Choice C is incorrect as the administration of Rh immune globulin is time-sensitive and not typically scheduled for a 6-week appointment. Choice D is incorrect because Rh immune globulin is necessary to prevent sensitization regardless of the number of pregnancies.
