Correct Answer: B

Rationale: The correct answer is Novolin R (Regular insulin) because it is used for continuous infusion to treat diabetic ketoacidosis. Novolin R has a rapid onset of action, making it suitable for this acute situation. Novolin L insulin (Choice A) is not typically used for continuous infusion in diabetic ketoacidosis. Novolin N insulin (Choice C) is an intermediate-acting insulin and is not ideal for rapid correction needed in diabetic ketoacidosis. Novolin U insulin (Choice D) is an ultra-long-acting insulin and is not appropriate for the immediate correction required in this scenario.

Correct Answer: B

Rationale: Weighing the client daily at the same time each day is the most accurate method for monitoring fluid balance. Changes in body weight can reflect fluid retention or loss. Measuring and recording fluid intake and output (Choice A) is important but may not provide immediate changes in fluid status. Assessing vital signs (Choice C) can offer some information but may not be as specific to fluid status as daily weighing. Checking the client's lungs for crackles (Choice D) is more related to assessing respiratory status rather than direct fluid monitoring.

Correct Answer: C

Rationale: In nursing care, implementation involves putting the nursing care plan into action. This step includes safeguarding the rights and privacy of the patient and their family by providing care in a respectful and confidential manner. Evaluation (A) is about assessing the effectiveness of the care provided. Planning (B) is the stage where specific interventions are designed. Assessment (D) is the initial step where data is collected to identify the patient's needs.

Correct Answer: A

Rationale: The correct answer is A: 'Nervousness, jitteriness, and diaphoresis.' Insulinomas cause hypoglycemia due to excessive insulin production, leading to symptoms such as nervousness (from the sympathetic response to hypoglycemia), jitteriness, and diaphoresis (sweating). Choices B, C, and D are incorrect. Flushed skin, dry mouth, and tented skin turgor (Choice B) are not typical signs of insulinoma. Polyuria, polydipsia, and polyphagia (Choice C) are classic symptoms of diabetes mellitus, not insulinoma. Hypertension, tachycardia, and feeling hot (Choice D) are more indicative of hyperthyroidism or a hypermetabolic state, rather than an insulinoma presentation.

Correct Answer: D

Rationale: The correct answer is D because feeding the infant with a rubber-tipped syringe reduces the risk of injury to the surgical site and prevents aspiration. Choice A is incorrect because feeding an infant with a cleft lip using a newborn nipple while in the recumbent position can increase the risk of aspiration. Choice B is incorrect as Betadine is not typically used on suture sites due to its cytotoxic effects. Choice C is incorrect because placing the infant in the prone position after feeding can also increase the risk of aspiration.
