1. A client with hyperkalemia is being treated in the emergency department. Which medication should the nurse prepare to administer?
- A. Potassium chloride
- B. Calcium gluconate
- C. Magnesium sulfate
- D. Sodium bicarbonate
Correct answer: B
Rationale: The correct answer is B, Calcium gluconate. In hyperkalemia, where potassium levels are elevated, calcium gluconate is administered to stabilize the myocardial cell membrane and protect the heart from potential arrhythmias. Potassium chloride (choice A) would worsen the condition by further increasing potassium levels. Magnesium sulfate (choice C) is not the primary treatment for hyperkalemia. Sodium bicarbonate (choice D) is used in metabolic acidosis, not specifically for hyperkalemia.
2. An adult woman with primary Raynaud phenomenon develops pallor and then cyanosis of her fingers. After warming her hands, the fingers turn red, and the client reports a burning sensation. What action should the nurse take?
- A. Apply a cool compress to the affected fingers for 20 minutes
- B. Secure a pulse oximeter to monitor the client's oxygen saturation
- C. Report the finding to the healthcare provider as soon as possible
- D. Continue to monitor the fingers until the color returns to normal
Correct answer: D
Rationale: In primary Raynaud phenomenon, the fingers go through a color sequence of pallor, cyanosis, and then redness when warmed. The burning sensation reported by the client indicates reperfusion. Continuing to monitor the fingers until the color returns to normal is appropriate in this situation as it ensures that the symptoms are resolving without the need for further intervention. Applying a cool compress could exacerbate the symptoms by causing vasoconstriction. Securing a pulse oximeter to monitor oxygen saturation is not necessary in this case as the issue is related to vasospasm rather than oxygenation. Reporting the finding to the healthcare provider is not urgent unless there are signs of complications or the symptoms do not improve with warming.
3. A client admitted with left-sided heart failure has a heart rate of 110 beats per minute and is becoming increasingly dyspneic. Which additional assessment finding by the nurse supports the client’s admitting diagnosis?
- A. Jugular vein distention.
- B. Crackles in the lung bases.
- C. Peripheral edema.
- D. Bounding peripheral pulses.
Correct answer: B
Rationale: The correct answer is B: Crackles in the lung bases. Crackles in the lung bases are indicative of pulmonary congestion, which is a classic sign of left-sided heart failure. Left-sided heart failure leads to a backup of blood into the lungs, causing fluid leakage into the alveoli and resulting in crackles upon auscultation. Choices A, C, and D are less specific to left-sided heart failure. Jugular vein distention can be seen in right-sided heart failure, peripheral edema can be seen in both right and left-sided heart failure, and bounding peripheral pulses are more indicative of conditions like hyperthyroidism or anemia rather than specifically supporting left-sided heart failure.
4. When performing postural drainage on a client with chronic obstructive pulmonary disease (COPD), which approach should the nurse use?
- A. Obtain arterial blood gases (ABGs) before the procedure.
- B. Explain that the client may be positioned in five different ways.
- C. Assist the patient into a position that will allow gravity to move secretions.
- D. Encourage the client to practice deep breathing throughout the procedure.
Correct answer: C
Rationale: The correct approach when performing postural drainage on a client with COPD is to assist the patient into a position that allows gravity to help move secretions. This position helps drain secretions from specific segments of the lungs. Obtaining arterial blood gases (Choice A) is not directly related to postural drainage. While the client may be placed in multiple positions during postural drainage, the key is to position them to facilitate the movement of secretions, not just any five positions as mentioned in Choice B. Encouraging deep breathing (Choice D) is a good nursing intervention for overall respiratory health but is not specifically related to the technique of postural drainage.
5. A client is receiving intravenous potassium chloride for hypokalemia. Which action should the nurse take to prevent complications during the infusion?
- A. Administer the infusion rapidly
- B. Monitor the infusion site for signs of infiltration
- C. Use a syringe pump for the infusion
- D. Flush the IV line with normal saline before starting the infusion
Correct answer: B
Rationale: The correct action to prevent complications during the infusion of potassium chloride is to monitor the infusion site for signs of infiltration. Rapid administration can lead to adverse effects, including cardiac arrhythmias. Using a syringe pump is not typically necessary for this infusion. Flushing the IV line with normal saline is a good practice but not directly related to preventing complications specifically during the infusion of potassium chloride.
