Correct Answer: B

Rationale: A PaCO2 level of 55 mm Hg indicates hypercapnia, which is common in clients with emphysema but may require further treatment if it leads to respiratory acidosis or distress. Elevated PaCO2 levels can indicate inadequate ventilation and impaired gas exchange, potentially leading to respiratory acidosis. The other results fall within normal ranges or compensated values for a client with chronic emphysema and do not necessarily indicate the need for immediate intervention.

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: D

Rationale: The correct answer is D. Elbow splints are utilized to prevent the child from touching the surgical site. However, it is essential to remove them periodically to conduct range-of-motion exercises to prevent joint stiffness. Choices A, B, and C are incorrect because providing an orthodontic pacifier, offering fluids using a straw, and cleansing the suture line with a cotton-tip swab are not directly related to postoperative care following a cleft palate repair.

Correct Answer: D

Rationale: The correct statement to include in the teaching about amniocentesis is that the client should report if they experience any contractions after the procedure. This is crucial because contractions could indicate preterm labor or other complications following the amniocentesis. Choices A and B are incorrect as a full bladder is not required for the procedure, and magnesium sulfate is not typically given before an amniocentesis. Choice C is incorrect as the procedure usually takes about 20-30 minutes to complete.

Correct Answer: B

Rationale: The correct answer is B: Conjunctival pallor. In anemia, there is a decrease in hemoglobin levels, leading to paleness of the conjunctiva. This is a common finding in individuals with anemia. Bounding pulse (choice A) is not typically associated with anemia but can be seen in conditions like hyperthyroidism. Elevated blood pressure (choice C) is not a common finding in anemia; instead, blood pressure may be low due to decreased oxygen-carrying capacity. Glossitis (choice D), or a swollen tongue, can be seen in certain types of anemia but is not as specific or common as conjunctival pallor.
