Question 1 of 5
While assessing clients on a medical-surgical unit, which client is at risk for hypokalemia?
Correct Answer: A
Rationale: The correct answer is A: Client with pancreatitis who has continuous nasogastric suctioning. Pancreatitis can lead to gastrointestinal losses of potassium, and continuous nasogastric suctioning can further exacerbate this potassium loss, putting the client at risk for hypokalemia. The other choices are incorrect because: B: ACE inhibitors can cause hyperkalemia, not hypokalemia. C: Blood transfusions can lead to hyperkalemia due to the potassium content in blood products. D: Uncontrolled diabetes and a serum pH level of 7.33 are not directly associated with hypokalemia.
Question 2 of 5
After teaching a client to increase dietary potassium intake, a nurse assesses the client's understanding. Which dietary meal selection indicates the client correctly understands the teaching?
Correct Answer: C
Rationale: The correct answer is C because it includes foods high in potassium. Raisins, whole wheat toast, and milk are good sources of potassium. Sausage might contain some potassium as well. A: This option lacks potassium-rich foods. B: While strawberries have some potassium, the overall meal lacks a sufficient amount. D: While oatmeal and peaches have potassium, coffee can actually inhibit potassium absorption.
Question 3 of 5
A client at risk for developing hyperkalemia states, 'I love fruit and usually eat it every day, but now I can't because of my high potassium level.' How should the nurse respond?
Correct Answer: C
Rationale: Rationale: Option C is correct because berries, cherries, apples, and peaches are indeed low in potassium compared to other fruits. This response acknowledges the client's love for fruits while providing suitable alternatives to manage potassium levels. By choosing these low-potassium fruits, the client can continue enjoying fruits without exacerbating hyperkalemia. Incorrect options: A: Potatoes and avocados are high in potassium, so they are not suitable substitutes. B: Cooking fruit does not significantly reduce its potassium content. D: This option lacks guidance and does not offer a solution to the client's concern about high potassium levels.
Question 4 of 5
A nurse is caring for a client who has a serum calcium level of 14 mg/dL. Which provider order should the nurse implement first?
Correct Answer: A
Rationale: The correct answer is A: Encourage oral fluid intake. When a client has hypercalcemia (serum calcium level of 14 mg/dL), the priority is to increase fluid intake to promote renal calcium excretion. This helps prevent complications such as renal calculi. The first step is to dilute the serum calcium by increasing fluid intake, which can help lower the serum calcium level. Connecting the client to a cardiac monitor (B) is not the priority as hypercalcemia affects the kidneys more than the heart. Assessing urinary output (C) is important but encouraging fluid intake is more immediate. Administering oral calcitonin (Calcimar) (D) is not the first action as it is a medication used for long-term management of hypercalcemia, not the immediate priority.
Question 5 of 5
A nurse is caring for an older adult client who is admitted with moderate dehydration. Which intervention should the nurse implement to prevent injury while in the hospital?
Correct Answer: D
Rationale: The correct answer is D because dangling the client on the bedside before ambulating helps prevent orthostatic hypotension and potential falls. This step allows the nurse to assess the client's tolerance to changes in position and reduces the risk of injury. A: Asking family members to speak quietly does not directly address the prevention of injury related to dehydration. B: Assessing urine parameters is important for monitoring hydration status but does not directly prevent injury. C: Encouraging fluid intake is important for rehydration but does not directly address the risk of injury during ambulation.
