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 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: D

Rationale: The correct answer is D: 'You may experience diarrhea with this medication.' Diarrhea is a common side effect of metformin, particularly when initiating the medication. It is important for clients to be aware of this potential side effect. Option A is incorrect because metformin is usually taken with meals to reduce gastrointestinal side effects. Option B is not directly related to metformin use. Option C is incorrect as muscle pain is not a common side effect of metformin and does not warrant stopping the medication.

Correct Answer: B

Rationale: In chronic kidney disease, the kidneys have impaired ability to activate vitamin D, leading to decreased production of calcitriol. Calcitriol is essential for calcium absorption in the intestines. Therefore, hypocalcemia is a common finding in chronic kidney disease. Hypernatremia (increased sodium levels) is not typically associated with chronic kidney disease. Low potassium and low magnesium are possible electrolyte imbalances in chronic kidney disease, but they are not as directly related to the impaired activation of vitamin D as hypocalcemia.

Correct Answer: A

Rationale: Carbohydrates should make up 45-65% of daily caloric intake as they are the body's main source of energy. This aligns with general dietary recommendations. Choice B is incorrect as protein should typically make up about 10-35% of daily caloric intake, not 55%. Choice C is also incorrect, as carbohydrates should ideally be between 45-65%, not 30%. Choice D is incorrect because protein should generally account for around 10-35% of total caloric intake, not 60%.
