Correct Answer: D

Rationale: An elevated serum creatinine level (1.8 mg/dL) is a significant indicator of potential kidney impairment. In acute kidney injury (AKI), serum creatinine levels rise due to decreased kidney function, reflecting the kidneys' inability to effectively filter waste from the blood. Magnesium level, BUN, and serum osmolality are not direct indicators of kidney function or risk of AKI. Magnesium levels are more related to electrolyte balance, BUN can be affected by factors other than kidney function, and serum osmolality reflects the concentration of solutes in the blood, not specifically kidney function.

Correct Answer: D

Rationale: The correct action when administering enoxaparin is not to expel the air bubble in the prefilled syringe. Expelling the air bubble may lead to the loss of medication and result in an incomplete dose. Aspirating for a blood return (Choice A) is not necessary for subcutaneous injections like enoxaparin. Inserting the needle at a 45-degree angle (Choice B) is not specific to administering enoxaparin. Administering the medication 2.54 cm (1 in) from the umbilicus (Choice C) is not a standard guideline for enoxaparin administration.

Correct Answer: B

Rationale: The correct action for the nurse to take when finding that the TPN solution is infusing too rapidly is to stop the TPN infusion. This is crucial to prevent fluid overload and ensure the client's safety. Sitting the client upright (Choice A) or turning the client on their left side (Choice C) are not appropriate responses to a rapidly infusing TPN solution and do not address the immediate issue of preventing complications from the rapid infusion. Adding insulin to the TPN infusion (Choice D) is not indicated unless specifically prescribed by the healthcare provider for the client's condition. Therefore, the priority action is to stop the TPN infusion to prevent potential harm.

Correct Answer: B

Rationale: During a client's transition into a new role, the presence of suicidal or homicidal ideation should be assessed due to the increased risk associated with significant life changes. This finding could indicate a need for immediate intervention. While assessing the client's ability to express feelings of guilt is important, it may not be the most critical aspect during this specific assessment. Changes in coping skills over time are relevant but might not be the primary focus during a role transition assessment. The client's involvement in community activities, although beneficial for social support, is not directly related to the immediate concerns of assessing a client transitioning into a new role.

Correct Answer: B

Rationale: The most appropriate intervention for a client experiencing acute alcohol withdrawal is to administer diazepam. Diazepam is a benzodiazepine commonly used to prevent seizures and manage the symptoms of alcohol withdrawal. Encouraging physical activity may not be safe during acute withdrawal as the client may be at risk for seizures and other complications. Monitoring for signs of dehydration is important but not the most immediate intervention needed in acute alcohol withdrawal. While encouraging the client to verbalize their feelings is beneficial for therapeutic communication, it is not the priority intervention when managing acute alcohol withdrawal.
