1. What is the most appropriate nursing action when a patient on anticoagulant therapy develops sudden, severe back pain?
- A. Administer pain medication
- B. Apply a cold compress to the back
- C. Assess for signs of internal bleeding
- D. Reposition the patient for comfort
Correct answer: C
Rationale: When a patient on anticoagulant therapy experiences sudden, severe back pain, the priority nursing action is to assess for signs of internal bleeding. Severe back pain in this context could be indicative of internal bleeding, such as a retroperitoneal bleed, which is a critical condition requiring immediate attention. Administering pain medication or applying a cold compress may mask or delay the identification of a potentially life-threatening situation. Repositioning the patient for comfort is not the priority when internal bleeding needs to be ruled out.
2. The patient diagnosed with athlete's foot (tinea pedis) states that he is relieved because it is only athlete's foot, and it can be treated easily. Which information about this condition should the nurse consider when formulating a response to the patient?
- A. It is contagious with frequent recurrences.
- B. It is most helpful to air-dry feet after bathing.
- C. It is treated with salicylic acid.
- D. It is caused by lice.
Correct answer: A
Rationale: Athlete's foot, also known as tinea pedis, is a contagious fungal infection that can easily spread to other body parts, particularly the hands. It often recurs if not properly treated, making choice A the correct answer. Choices B and C are incorrect because while it is beneficial to air-dry feet after bathing to prevent moisture buildup, athlete's foot is commonly treated with antifungal medications, not salicylic acid. Choice D is incorrect because athlete's foot is caused by a fungal infection, not lice.
3. A client with bipolar disorder is prescribed lithium. What is the most important instruction the nurse should provide?
- A. Avoid foods high in potassium while taking this medication.
- B. Take your medication with food to prevent nausea.
- C. Be sure to maintain a consistent sodium intake.
- D. You can stop taking the medication once your symptoms improve.
Correct answer: C
Rationale: Maintaining a consistent sodium intake is crucial for clients taking lithium because changes in sodium levels can impact lithium concentrations, potentially leading to toxicity. It is essential to avoid excessive sodium intake, as both low and high levels can affect lithium levels. Choices A, B, and D are incorrect. A high potassium diet is not a concern with lithium therapy. While taking lithium with food can help reduce gastrointestinal side effects, it is not the most important instruction. Finally, abruptly stopping lithium can lead to a recurrence of symptoms or a worsening of the condition, so it is vital to follow the prescribed regimen.
4. When using an open irrigation technique for a client's catheter, what action should the nurse take?
- A. Subtract the amount of irrigant used from the client's urine output.
- B. Add the amount of irrigant used to the urine output measurement.
- C. Measure the amount of irrigant used separately from the urine output.
- D. Document the total amount of fluid used for irrigation only.
Correct answer: A
Rationale: The correct action for the nurse to take when using an open irrigation technique for a client's catheter is to subtract the amount of irrigant used from the client's urine output. This subtraction helps accurately assess the client's output by accounting for the volume of irrigant introduced. Choice B is incorrect because adding the irrigant to the urine output measurement would falsely inflate the total output, leading to inaccurate assessment. Choice C is incorrect as measuring the amount of irrigant separately does not provide an accurate assessment of the client's total output as it disregards the irrigant's contribution. Choice D is incorrect as documenting the total fluid used for irrigation only does not differentiate between the irrigant and the client's actual urine output, which is crucial for accurate monitoring and assessment.
5. A client complains of paresthesia in the fingers and toes and experiences hand spasms when the blood pressure cuff is inflated. Which serum laboratory finding should the nurse expect to find when assessing the client?
- A. Elevated serum calcium
- B. Low serum magnesium
- C. Low serum calcium
- D. Elevated serum potassium
Correct answer: C
Rationale: The correct answer is C: Low serum calcium. Hand spasms and paresthesia are indicative of potential hypocalcemia, which is characterized by low serum calcium levels. Elevated serum calcium (Choice A) is not consistent with the symptoms described. Low serum magnesium (Choice B) and elevated serum potassium (Choice D) are not typically associated with hand spasms and paresthesia.
