1. IV potassium chloride (KCl) 60 mEq is prescribed for the treatment of a patient with severe hypokalemia. Which action should the nurse take?
- A. Administer the KCl as a rapid IV bolus.
- B. Infuse the KCl at a rate of 10 mEq/hour.
- C. Only give the KCl through a central venous line.
- D. Discontinue cardiac monitoring during the infusion.
Correct answer: B
Rationale: The correct action for the nurse to take is to infuse the KCl at a rate of 10 mEq/hour. Rapid IV infusion of KCl can lead to cardiac arrest due to its potential for causing hyperkalemia. While KCl can be administered through peripheral veins, central venous lines are not necessary unless specified. It is crucial to continue cardiac monitoring during potassium infusion to promptly identify and manage any potential dysrhythmias that may occur.
2. A patient who is lethargic and exhibits deep, rapid respirations has the following arterial blood gas (ABG) results: pH 7.32, PaO2 88 mm Hg, PaCO2 37 mm Hg, and HCO3 16 mEq/L. How should the nurse interpret these results?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: A
Rationale: The patient's pH is below the normal range (7.35-7.45), and the HCO3 is also below the normal range (22-26 mEq/L), indicating an acidic environment, which is consistent with metabolic acidosis. The ABGs provided do not support respiratory acidosis or alkalosis, as the PaCO2 is within the normal range (35-45 mm Hg) despite the patient's deep, rapid respirations. Therefore, the correct interpretation is metabolic acidosis.
3. A patient has a serum calcium level of 7.0 mEq/L. Which assessment finding is most important for the nurse to report to the health care provider?
- A. The patient is experiencing laryngeal stridor.
- B. The patient complains of generalized fatigue.
- C. The patient has not had a bowel movement for 4 days.
- D. The patient has numbness and tingling of the lips.
Correct answer: A
Rationale: The correct answer is A - 'The patient is experiencing laryngeal stridor.' Hypocalcemia can cause laryngeal stridor, which may lead to respiratory arrest. Rapid action is required to correct the patient’s calcium level to prevent a life-threatening situation. Choices B, C, and D are also symptoms of hypocalcemia, but laryngeal stridor takes precedence due to its potential to quickly progress to a critical condition.
4. What is the first action the nurse should take when a patient complains of acute chest pain and dyspnea soon after insertion of a centrally inserted IV catheter?
- A. Notify the health care provider.
- B. Offer reassurance to the patient.
- C. Auscultate the patient’s breath sounds
- D. Give the prescribed PRN morphine sulfate IV
Correct answer: C
Rationale: The correct first action for the nurse to take when a patient complains of acute chest pain and dyspnea after the insertion of a centrally inserted IV catheter is to auscultate the patient's breath sounds. This is important to assess for any potential complications such as embolism or pneumothorax, which can present with such symptoms. Auscultation can provide immediate information on the patient's respiratory status and guide further interventions. Notifying the health care provider, offering reassurance, or administering morphine should only be considered after assessing the patient's condition through auscultation.
5. An older patient receiving iso-osmolar continuous tube feedings develops restlessness, agitation, and weakness. Which laboratory result should the nurse report to the health care provider immediately?
- A. K+ 3.4 mEq/L (3.4 mmol/L)
- B. Ca+2 7.8 mg/dL (1.95 mmol/L)
- C. Na+ 154 mEq/L (154 mmol/L)
- D. PO4-3 4.8 mg/dL (1.55 mmol/L)
Correct answer: C
Rationale: The correct answer is C. The elevated serum sodium level (154 mEq/L) is consistent with the patient's neurologic symptoms of restlessness, agitation, and weakness, indicating a need for immediate action to prevent complications like seizures. The potassium level (3.4 mEq/L) and calcium level (7.8 mg/dL) are slightly off from normal but do not require immediate action. The phosphate level (4.8 mg/dL) is normal and not related to the symptoms presented by the patient.
