A patient with renal failure has been taking aluminum hydroxide/magnesium hydroxide suspension (Maalox) at home for indigestion. The patient arrives for outpatient hemodialysis and is unresponsive to questions and has decreased deep tendon reflexes. Which action should the dialysis nurse take first?
- A. Notify the patient's health care provider.
- B. Obtain an order to draw a potassium level.
- C. Review the magnesium level on the patient's chart.
- D. Teach the patient about the risk of magnesium-containing antacids
Correct Answer: A
Rationale: The health care provider should be notified immediately. The patient has a history and manifestations consistent with hypermagnesemia. The nurse should check the chart for a recent serum magnesium level and make sure that blood is sent to the laboratory for immediate electrolyte and chemistry determinations. Dialysis should correct the high magnesium levels. The patient needs teaching about the risks of taking magnesium-containing antacids. Monitoring of potassium levels also is important for patients with renal failure, but the patient's current symptoms are not consistent with hyperkalemia.

The nurse is caring for a patient with a massive burn injury and possible hypovolemia. Which assessment data will be of most concern to the nurse?
- A. Blood pressure is 90/40 mm Hg.
- B. Urine output is 30 mL over the last hour.
- C. Oral fluid intake is 100 mL over the last 8 hours.
- D. There is prolonged skin tenting over the sternum.
Correct Answer: A
Rationale: The correct answer is A: "Blood pressure is 90/40 mm Hg." A low blood pressure reading of 90/40 mm Hg indicates that the patient may be developing hypovolemic shock due to intravascular fluid loss from the burn injury. This finding is of utmost concern as it suggests systemic hypoperfusion, requiring immediate intervention to prevent complications. Choices B, C, and D also indicate signs of dehydration and the need to increase fluid intake; however, they are not as urgent as addressing the hypotension and potential shock presented in choice A.
A male client with unstable angina needs a cardiac catheterization. So the healthcare provider explains the risks and benefits of the procedure and then leaves to set up for the procedure. When the nurse presents the consent form for signature, the client hesitates and asks how the wires will keep his heart going. Which action should the nurse take?
- A. Answer the client's specific questions with a short, understandable explanation
- B. Postpone the procedure until the client understands the risks and benefits
- C. Call the client's next of kin and ask them to provide verbal consent
- D. Page the healthcare provider to return and provide additional explanation
Correct Answer: D
Rationale: The correct action for the nurse to take in this situation is to page the healthcare provider to return and provide additional explanation. It is crucial for the client to have a clear understanding of the procedure, including its risks and benefits, before signing the consent form. While the nurse can provide general information, the detailed explanation of how the procedure works and its effects should come from the healthcare provider who will perform the procedure. Postponing the procedure until the client understands is appropriate, but the immediate need is to clarify the client's concerns with the healthcare provider. Calling the client's next of kin for verbal consent is not the correct course of action as the client is present and able to provide consent after receiving adequate information.
The nurse is preparing to send a client to the cardiac catheterization lab for an angioplasty. Which client report is most important for the nurse to explore further prior to the procedure?
- A. Experiences facial swelling after eating crab
- B. Reports left chest wall pain prior to the admission
- C. Verbalizes a fear of being in a confined space
- D. Drank a glass of water
Correct Answer: A
Rationale: The correct answer is A. Allergy to shellfish can indicate a potential allergy to iodine, which is used in contrast dye for the procedure. This must be explored further to prevent an allergic reaction. Choice B is not directly related to the angioplasty procedure. Choice C pertains to claustrophobia, which can be addressed but is not directly related to the safety of the procedure. Choice D is a routine activity and does not pose a risk to the client during the procedure.
The nurse is caring for a patient who has a central venous access device (CVAD). Which action by the nurse is appropriate?
- A. Avoid using friction when cleaning around the CVAD insertion site.
- B. Use the push-pause method to flush the CVAD after giving medications.
- C. Obtain an order from the healthcare provider to change the CVAD dressing.
- D. Position the patient's face away from the CVAD during injection cap changes.
Correct Answer: B
Rationale: The correct answer is B because using the push-pause method to flush the CVAD after giving medications helps remove debris from the CVAD lumen and decreases the risk for clotting. Choice A is incorrect because friction should be used when cleaning the CVAD insertion site to decrease infection risk. Choice C is incorrect because obtaining an order from the healthcare provider to change the CVAD dressing is not necessary; the dressing should be changed when damp, loose, or visibly soiled. Choice D is incorrect because the patient should face away from the CVAD during cap changes to minimize the risk of contamination.
A child is diagnosed with acquired aplastic anemia. The nurse knows that this child has the best prognosis with which treatment regimen?
- A. blood transfusion
- B. chemotherapy
- C. bone marrow transplantation
- D. immunosuppressive therapy
Correct Answer: C
Rationale: In the case of acquired aplastic anemia, bone marrow transplantation offers the best chance of cure as it replaces the abnormal stem cells with healthy ones. Blood transfusion may provide temporary relief by replacing blood cells, but it does not address the root cause of the condition. Chemotherapy may be used in some cases, but it is not the preferred treatment for acquired aplastic anemia. While immunosuppressive therapy can be effective, especially in patients who are not candidates for a bone marrow transplant, it is not the first-line treatment and does not offer the same potential for a cure as bone marrow transplantation.
