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.

The home health nurse cares for an alert and oriented older adult patient with a history of dehydration. Which instructions should the nurse give to this patient related to fluid intake?
- A. Increase fluids if your mouth feels dry.
- B. More fluids are needed if you feel thirsty.
- C. Drink more fluids in the late evening hours.
- D. If you feel lethargic or confused, you need more to drink.
Correct Answer: A
Rationale: The correct answer is A. An alert, older patient can self-assess for signs of dehydration like dry mouth. This instruction is appropriate as it encourages the patient to respond to early signs of dehydration. Choice B is incorrect because the thirst mechanism decreases with age and feeling thirsty may not accurately indicate the need for fluids. Choice C is incorrect as many older patients prefer to limit evening fluid intake to enhance sleep quality. Choice D is incorrect because an older adult who is lethargic or confused may not be able to accurately assess their need for fluids.
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 54-year-old male client and his wife were informed this morning that he has terminal cancer. Which nursing intervention is likely to be most beneficial?
- A. Ask the wife how she would like to participate in the client's care
- B. Provide the wife with information about hospice
- C. Encourage the wife to visit after painful treatments are completed
- D. Refer the wife to a support group for family members of those dying of cancer
Correct Answer: A
Rationale: The most beneficial nursing intervention in this situation is to ask the wife how she would like to participate in the client's care. Involving the spouse in the care of the terminally ill client can provide comfort, support, and a sense of contribution during a challenging time. Providing information about hospice (B) is important but may not be the immediate priority. Encouraging the wife to visit after treatments are completed (C) may delay her involvement in the care. Referring her to a support group (D) is a good idea but might be more suitable at a later stage.
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.
A patient is admitted to the emergency department with severe fatigue and confusion. Laboratory studies are done. Which laboratory value will require the most immediate action by the nurse?
- A. Arterial blood pH is 7.32.
- B. Serum calcium is 18 mg/dL.
- C. Serum potassium is 5.1 mEq/L
- D. Arterial oxygen saturation is 91%.
Correct Answer: B
Rationale: The correct answer is B. A serum calcium level of 18 mg/dL is significantly elevated, posing a high risk for cardiac dysrhythmias. Immediate action is required to initiate cardiac monitoring and notify the healthcare provider. While the abnormalities in arterial blood pH, serum potassium, and arterial oxygen saturation also need attention, they are not as immediately life-threatening as the critically high serum calcium level. Therefore, addressing the serum calcium level takes precedence in this scenario.
