A nurse is caring for a client who has chronic kidney disease and a serum potassium level of 6.0 mEq/L. Which of the following findings should the nurse expect?

Correct Answer: D

Rationale: The correct answer is D: Hyperkalemia. In chronic kidney disease, there is decreased renal excretion of potassium, leading to elevated serum potassium levels. Hypokalemia (Choice A) is low potassium levels, which is the opposite finding in this scenario. Hypocalcemia (Choice B) is decreased calcium levels and is not directly related to chronic kidney disease or elevated potassium levels. Hypoglycemia (Choice C) is low blood sugar levels and is not typically associated with chronic kidney disease or high potassium levels.

Correct Answer: D

Rationale: The correct answer is D: Aspartate aminotransferase (AST) 60 units/L. An elevated AST level indicates liver damage, which can be a side effect of methotrexate and should be reported. Elevated white blood cell count (choice A), platelet count (choice B), or normal hemoglobin level (choice C) are not directly related to methotrexate therapy for rheumatoid arthritis.

Correct Answer: D

Rationale: The correct action for the nurse to take when continuous bubbling is noted in the water seal chamber of a chest tube is to apply a dressing over the insertion site. Continuous bubbling indicates an air leak, and applying a dressing helps manage this issue by providing a seal. Clamping the chest tube or replacing the drainage system is not appropriate in this situation as it can lead to complications such as tension pneumothorax or inadequate drainage of the pleural space.

Correct Answer: A

Rationale: Naloxone is the correct answer. Naloxone is specifically used to reverse the effects of opioid overdose by binding to opioid receptors and blocking the effects of opioids. Epinephrine is mainly used to treat severe allergic reactions, Atropine is used for certain types of heart conditions and to reduce salivation or respiratory secretions, and Lidocaine is a local anesthetic used for numbing purposes. Therefore, choices B, C, and D are incorrect in the context of reversing opioid overdose.

Correct Answer: B

Rationale: Correct Answer: The healthcare professional should review serum creatinine levels before administering metformin to assess kidney function. Metformin is excreted by the kidneys, and checking serum creatinine helps prevent lactic acidosis, a potential side effect in individuals with impaired renal function. Choice A: Potassium levels are not directly related to the administration of metformin. While monitoring potassium levels is important for some medications, it is not the priority when initiating metformin. Choice C: Sodium levels are not typically assessed specifically before starting metformin. It is not a routine lab test required prior to metformin administration. Choice D: Hemoglobin A1C reflects long-term blood sugar control and is not a lab test that needs to be reviewed before initiating metformin. It is used to monitor diabetes management over time, not for immediate medication administration considerations.

Correct Answer: C

Rationale: The correct answer is C: Diaphoresis. Diaphoresis, which is excessive sweating, is a common sign of hypoglycemia due to the activation of the sympathetic nervous system. Tachycardia (choice A) is more commonly associated with hyperglycemia. Dry mouth (choice B) is not a typical finding in hypoglycemia but may be seen in hyperglycemia. Increased appetite (choice D) is not a typical sign of hypoglycemia and is more commonly associated with hyperglycemia.

Correct Answer: B

Rationale: When caring for a patient with a central line, monitoring for infection is crucial. This is because central lines can introduce bacteria into the bloodstream, leading to serious infections. While flushing the line daily and changing the dressing weekly are important aspects of central line care, monitoring for infection takes precedence. Infections can occur rapidly and have severe consequences, so early detection through vigilant monitoring is key. Replacing the central line every week is not a standard practice and should only be done when clinically indicated, such as in cases of infection or malfunction.

Correct Answer: A

Rationale: The correct answer is hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss through increased urinary excretion, making hypokalemia the most concerning electrolyte imbalance. Hyponatremia (Choice B) is not typically associated with furosemide use. Hyperkalemia (Choice C) is less likely due to furosemide's potassium-wasting effect. Hypercalcemia (Choice D) is not a common electrolyte imbalance seen with furosemide.

Correct Answer: A

Rationale: An effective leader advocates for the unit's success and its members. Choice B is incorrect because prioritizing staff requests over client needs does not align with effective leadership, which should focus on client-centered care. Choice C is incorrect as sharing personal opinions to influence the group's values can be biased and may not reflect the best interest of the team. Choice D is incorrect because while providing client care is essential, effective leadership involves more than routine tasks and includes guiding and supporting the team.
