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 action for the nurse to take is to ensure that the newborn wears a diaper. This is important to prevent skin irritation during phototherapy. Choice A is incorrect as newborns should be breastfed or formula-fed, not given glucose water. Choice B is unnecessary and may interfere with the effectiveness of phototherapy. Choice D is inappropriate as lotions can interfere with the phototherapy and increase the risk of skin damage.

Correct Answer: C

Rationale: Jugular vein distention is a classic sign of left-sided heart failure due to fluid overload in the pulmonary circulation. This occurs because the heart's left side is unable to pump effectively, causing increased pressure in the pulmonary veins and leading to blood backing up into the pulmonary circulation. Peripheral edema (choice A) and dependent edema (choice D) are more commonly associated with right-sided heart failure where blood pools in the systemic circulation, causing swelling in the extremities. Bradycardia (choice B) is not typically a direct consequence of left-sided heart failure; instead, tachycardia is more commonly seen as the heart compensates for its reduced efficiency.

Correct Answer: D

Rationale: Placing the client's left arm on a pillow while they are sitting helps prevent shoulder displacement and provides support for the limb post-stroke. This positioning is important to maintain proper alignment and prevent complications. Choices A, B, and C are incorrect because placing food on the left side of the mouth, providing total assistance with ADLs, and maintaining the client on bed rest do not directly address the specific needs related to unilateral paralysis and dysphagia post right hemispheric stroke.

Correct Answer: B

Rationale: Administering flumazenil is the priority to reverse the effects of diazepam overdose. Monitoring the IV site for thrombophlebitis (choice A) is important but not the next immediate action. Evaluating the client for further suicidal behavior (choice C) is important but not the priority at this moment. Initiating seizure precautions (choice D) is not the priority action in this scenario.
