Question 1 of 5
A nurse is assessing a client with hypokalemia and notes that the client's handgrip strength has diminished since the previous assessment 1 hour ago. Which action should the nurse take first?
Correct Answer: A
Rationale: The correct action for the nurse to take first is to assess the client's respiratory rate, rhythm, and depth (Choice A). Diminished handgrip strength in a client with hypokalemia could indicate potential respiratory muscle weakness, which can lead to respiratory distress or failure. By assessing the client's respiratory status, the nurse can determine if immediate intervention is needed to support breathing. Choice B is incorrect because measuring the client's pulse and blood pressure may not address the underlying issue of respiratory muscle weakness. Choice C is incorrect as it delays potential life-saving interventions by simply documenting findings. Choice D is incorrect as calling the healthcare provider should come after addressing the client's immediate respiratory needs.
Question 2 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 3 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 4 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.
Question 5 of 5
A nurse assesses a client who is admitted for treatment of fluid overload. Which manifestations should the nurse expect to find? (Select all that do not apply.)
Correct Answer: C
Rationale: Step 1: Fluid overload leads to increased fluid volume in the body, causing skin to appear pale, cool, and clammy due to poor circulation. Step 2: "Warm and pink skin" is not a typical manifestation of fluid overload. Step 3: Therefore, the correct answer is C. Summary: A: Increased pulse rate - Possible in fluid overload due to increased volume causing increased workload on the heart. B: Distended neck veins - Common in fluid overload due to increased venous pressure. C: Warm and pink skin - Incorrect, as skin is usually pale, cool, and clammy. D: Skeletal muscle weakness - Not directly related to fluid overload.
