Correct Answer: C

Rationale: In this scenario, the nurse should ask the provider to prescribe a different antibiotic instead of administering amoxicillin to a client with a known penicillin allergy. Choice A is incorrect because administering amoxicillin to a client with a penicillin allergy can lead to an allergic reaction. Choice B is not the best option as simply verifying the client's allergy status does not address the potential harm of giving amoxicillin. Choice D is irrelevant as checking the client's skin for rashes does not address the issue of administering a potentially harmful medication. Therefore, the most appropriate action is to request a different antibiotic from the provider to ensure the safety of the client.

Correct Answer: A

Rationale: The correct answer is A: Increased creatinine. In chronic kidney disease, the kidneys are unable to filter waste effectively, leading to a buildup of creatinine in the blood. This results in increased creatinine levels in laboratory tests. Choice B, increased hemoglobin, is not typically associated with chronic kidney disease. Choice C, increased bicarbonate, is also not a common finding in chronic kidney disease; in fact, metabolic acidosis with decreased bicarbonate levels is more common. Choice D, increased calcium, is not expected in chronic kidney disease; instead, calcium levels may be low due to impaired kidney function.

Correct Answer: C

Rationale: The correct answer is C because avoiding popcorn and fresh pineapple helps prevent complications with an ascending colostomy. Statements A, B, and D are incorrect. Statement A is inaccurate as it takes time for bowel function to normalize after surgery. Statement B is incorrect as alcohol can be irritating to the skin; gentle soap and water are recommended for cleaning. Statement D is incorrect as bruising around the stoma is not an expected outcome of colostomy creation.

Correct Answer: C

Rationale: The correct answer is C. Using both breasts at each feeding helps ensure adequate milk production and consumption. Option A is incorrect because breastfeeding should be done on demand rather than following a strict schedule. Option B is incorrect as limiting feeding time to 5 minutes per breast may not provide the baby with enough milk. Option D is also incorrect as pumping should not replace direct breastfeeding unless there is a specific medical reason to do so.

Correct Answer: D

Rationale: An elevated serum creatinine level indicates impaired kidney function, which can affect the metabolism and excretion of enoxaparin, potentially leading to increased drug levels and risk of bleeding. Therefore, it is crucial to report a high serum creatinine level before administering enoxaparin. Platelet count, aPTT, and sodium levels are not directly related to the administration of enoxaparin and would not impact its use; hence, they do not need to be reported before starting the medication.
