A patient has a parenteral nutrition infusion of 25% dextrose. A student nurse asks the nurse why a peripherally inserted central catheter was inserted. Which response by the nurse is most appropriate?
- A. There is a decreased risk for infection when 25% dextrose is infused through a central line.
- B. The prescribed infusion can be given much more rapidly when the patient has a central line.
- C. The 25% dextrose is hypertonic and will be more rapidly diluted when given through a central line.
- D. The required blood glucose monitoring is more accurate when samples are obtained from a central line.
Correct Answer: C
Rationale: The 25% dextrose solution is hypertonic. Shrinkage of red blood cells can occur when solutions with dextrose concentrations greater than 10% are administered IV. Blood glucose testing is not more accurate when samples are obtained from a central line. The infection risk is higher with a central catheter than with peripheral IV lines. Hypertonic or concentrated IV solutions are not given rapidly.

When assessing a male client, the nurse finds that he is fatigued, and is experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which?
- A. Hyperphosphatemia
- B. Hypocalcemia
- C. Hypermagnesemia
- D. Hypokalemia
Correct Answer: D
Rationale: The correct answer is D, Hypokalemia. Generalized weakness, muscle weakness, leg cramps, and cardiac dysrhythmias are manifestations of hypokalemia. Checking the potassium level is essential in this case. Hypocalcemia typically presents with facial muscle spasms, not the symptoms mentioned. Hypermagnesemia does not typically cause the symptoms described. It's important to note that orange juice is high in potassium and would be advisable to drink if the patient was hypokalemic. Loose stools are more commonly associated with hyperkalemia, not hypokalemia.
How should the nurse interpret the following arterial blood gas results for a patient who had a tracheostomy placed after a motor vehicle crash: pH 7.48, PaO2 85 mm Hg, PaCO2 32 mm Hg, and HCO3 25 mEq/L?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct Answer: D
Rationale: The patient's pH of 7.48 indicates alkalosis, and the low PaCO2 of 32 mm Hg suggests a respiratory cause. The HCO3 level is normal, ruling out metabolic causes. Therefore, the correct interpretation is respiratory alkalosis. Options A, B, and C are incorrect as they do not align with the pH and PaCO2 values provided.
The nurse in the emergency department observes a colleague viewing the electronic health record (EHR) of a client who holds an elected position in the community. The client is not a part of the colleague's assignment. Which action should the nurse implement?
- A. Communicate the colleague's actions to the unit charge nurse
- B. Send an email to facility administration reporting the action
- C. Write an anonymous complaint to a professional website
- D. Post a comment about the action on a staff discussion board
Correct Answer: A
Rationale: Viewing the EHR of a client who is not under your care is a violation of HIPAA regulations, regardless of the client's social status or your curiosity. The appropriate action to take in this situation is to communicate the colleague's actions to the unit charge nurse. The charge nurse can then escalate the issue through the appropriate channels within the organization. Reporting to the charge nurse ensures that the incident is handled internally and in accordance with organizational policies and procedures. Sending an email to facility administration, writing an anonymous complaint to a professional website, or posting a comment on a staff discussion board are not the recommended actions as they may not address the issue effectively and could potentially violate confidentiality further.
A patient who has been receiving diuretic therapy is admitted to the emergency department with a serum potassium level of 3.0 mEq/L. The nurse should alert the healthcare provider immediately that the patient is on which medication?
- A. Oral digoxin (Lanoxin) 0.25 mg daily
- B. Ibuprofen (Motrin) 400 mg every 6 hours
- C. Metoprolol (Lopressor) 12.5 mg orally daily
- D. Lantus insulin 24 U subcutaneously every evening
Correct Answer: A
Rationale: The correct answer is A. Hypokalemia increases the risk for digoxin toxicity, which can lead to serious dysrhythmias. Therefore, with a low potassium level, the nurse should immediately alert the healthcare provider about the patient being on oral digoxin. Choices B, C, and D do not pose as much concern with the given potassium level. However, further assessment is still required for these medications.
The nurse is teaching the parent of a child newly diagnosed with a latex allergy. Which information by the parents indicates a need for further teaching?
- A. Rubber-free toys, such as wooden building blocks, are good choices for the child.
- B. Only foil balloons will be used for the child's birthday party.
- C. A diet of healthy fruits, such as bananas and kiwis, is best for the child.
- D. An epinephrine auto-injector will be on hand to treat allergic reactions.
Correct Answer: C
Rationale: The correct answer is C. Bananas and kiwis are foods that can cross-react with latex allergy, indicating that the parents need further teaching on managing latex allergies. Choices A, B, and D are correct as rubber-free toys, using foil balloons, and having an epinephrine auto-injector are appropriate measures to prevent and manage allergic reactions in a child with a latex allergy.
