1. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value is most concerning?
- A. Serum glucose of 300 mg/dL
- B. Blood pressure of 140/90 mmHg
- C. Serum osmolarity of 320 mOsm/kg
- D. Serum pH of 7.30
Correct answer: C
Rationale: In a client with hyperglycemic hyperosmolar syndrome (HHS), a serum osmolarity of 320 mOsm/kg is the most concerning laboratory value. This high osmolarity indicates severe dehydration, which can lead to serious complications. Elevated serum glucose levels (choice A) are expected in HHS but do not directly reflect dehydration. Blood pressure (choice B) and serum pH (choice D) are important parameters to monitor but are not the most concerning values in HHS compared to serum osmolarity.
2. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value requires immediate intervention?
- A. Serum potassium of 5.5 mEq/L
- B. Serum creatinine of 2.5 mg/dL
- C. Hemoglobin of 10 g/dL
- D. White blood cell count of 10,000/mm³
Correct answer: A
Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client receiving erythropoietin therapy as it indicates hyperkalemia, requiring immediate intervention. High potassium levels can lead to severe cardiac arrhythmias and must be addressed promptly. The other laboratory values, though abnormal, do not present immediate life-threatening risks as hyperkalemia does.
3. A school nurse is called to the soccer field because a child has a nosebleed (epistaxis). In what position should the nurse place the child?
- A. Sitting up and leaning forward
- B. Lying flat with legs elevated
- C. Lying on the side with the head slightly raised
- D. Sitting up and tilting the head back
Correct answer: A
Rationale: The child with a nosebleed (epistaxis) should be placed in a sitting position, leaning forward, to prevent blood from flowing down the throat. This position helps to control the bleeding and prevents the child from swallowing blood, which can cause nausea or vomiting. Choice B is incorrect because elevating the legs is not recommended for nosebleeds. Choice C is incorrect because lying on the side with the head slightly raised is not the optimal position for managing a nosebleed. Choice D is incorrect because tilting the head back can lead to blood flowing down the throat and potentially cause aspiration.
4. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value is most concerning?
- A. Serum potassium of 6.5 mEq/L
- B. Serum bicarbonate of 18 mEq/L
- C. Serum glucose of 350 mg/dl
- D. Serum sodium of 135 mEq/L
Correct answer: A
Rationale: A serum potassium level of 6.5 mEq/L is concerning in a client with COPD exacerbation as it may lead to life-threatening arrhythmias, requiring immediate intervention. Hyperkalemia can cause cardiac arrhythmias, which pose a significant risk to the patient's life. Options B, C, and D are not typically associated with immediate life-threatening risks in the context of a COPD exacerbation.
5. An older female client tells the nurse that her muscles have gradually been getting weaker over time. What is the best initial response by the nurse?
- A. Explain that this is an expected occurrence with aging.
- B. Observe the lower extremities for signs of muscle atrophy.
- C. Review the medical record for recent diagnostic test results.
- D. Ask the client to describe the changes that have occurred.
Correct answer: D
Rationale: The best initial response by the nurse should be to ask the client to describe the changes that have occurred. This open-ended question allows the nurse to gather valuable information directly from the client, aiding in assessing the situation accurately and formulating an appropriate care plan. Choice A is incorrect as assuming muscle weakness is an expected occurrence with aging without further assessment may overlook potential underlying issues. Choice B is premature as it jumps straight to physical examination without first gathering subjective data. Choice C is unnecessary at this point as reviewing diagnostic test results should come after initial assessment and data collection from the client.
