1. A client who has just undergone bronchoscopy was returned to the nursing unit 1 hour ago. With which assessment finding is the nurse most concerned?
- A. Oxygen saturation of 97%
- B. Equal breath sounds in both lungs
- C. Absence of cough and gag reflexes
- D. Respiratory rate of 20 breaths/min
Correct answer: C
Rationale: The correct answer is C. The absence of cough and gag reflexes is the most concerning finding for the nurse because it indicates a lack of protective airway reflexes, putting the client at risk of aspiration. Oxygen saturation of 97% is within the normal range and indicates adequate oxygenation. Equal breath sounds in both lungs are a positive finding, indicating no significant abnormalities. A respiratory rate of 20 breaths/min is also within the normal range and does not raise immediate concerns. Therefore, the absence of cough and gag reflexes poses the highest risk to the client's airway safety.
2. A client with acute kidney injury (AKI) weighing 50kg and having a potassium level of 6.7mEq/L (6.7mmol/L) is admitted to the hospital. Which prescribed medication should the nurse administer first?
- A. Calcium acetate, one tablet by mouth
- B. Sodium polystyrene sulfonate, 15 grams by mouth
- C. Epoetin Alfa, recombinant, 2,500 units subcutaneously
- D. Sevelamer, one tablet by mouth
Correct answer: B
Rationale: In a client with acute kidney injury (AKI) and hyperkalemia, the priority intervention is to lower the potassium level swiftly. Sodium polystyrene sulfonate is a medication used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, reducing the overall potassium levels. Calcium acetate, epoetin alfa, and sevelamer are not indicated for the immediate reduction of potassium levels in hyperkalemia. Calcium acetate is used to control phosphate levels, epoetin alfa is a medication to treat anemia by stimulating red blood cell production, and sevelamer is a phosphate binder used in chronic kidney disease to reduce phosphate levels.
3. A client with chronic kidney disease is admitted with complaints of fatigue and swelling in the lower extremities. What laboratory finding is most important for the nurse to report?
- A. Serum creatinine level of 2.0 mg/dL.
- B. Hemoglobin level of 8 g/dL.
- C. Potassium level of 5.6 mEq/L.
- D. Blood urea nitrogen (BUN) level of 25 mg/dL.
Correct answer: B
Rationale: The correct answer is B. A hemoglobin level of 8 g/dL suggests anemia, which commonly occurs in clients with chronic kidney disease and requires prompt intervention. Reporting this finding is crucial to address the anemic condition. Choices A, C, and D are important in the context of chronic kidney disease but do not directly relate to the symptoms of fatigue and swelling in the lower extremities described in the scenario.
4. A client is admitted with a diagnosis of septic shock. Which clinical finding requires immediate intervention?
- A. Blood pressure of 90/60 mmHg
- B. Temperature of 100.4°F
- C. Heart rate of 120 beats per minute
- D. Urine output of 30 ml/hour
Correct answer: C
Rationale: In a client with septic shock, a heart rate of 120 beats per minute is a critical clinical finding that requires immediate intervention. A rapid heart rate can indicate worsening sepsis and inadequate tissue perfusion. Correcting the underlying cause of the tachycardia and stabilizing the heart rate is crucial in managing septic shock. The other options, while important, do not represent an immediate threat to the patient's condition. A blood pressure of 90/60 mmHg may be expected in septic shock, a temperature of 100.4°F is mildly elevated, and a urine output of 30 ml/hour, though decreased, may not be an immediate concern in the context of septic shock.
5. An antibiotic IM injection for a 2-year-old child is ordered. The total volume of the injection equals 2.0 ml. The correct action is to
- A. administer the medication in 2 separate injections
- B. give the medication in the ventrogluteal site
- C. call to get a smaller volume ordered
- D. check with the pharmacy for a liquid form of the medication
Correct answer: A
Rationale: Administering the medication in 2 separate injections is the correct action. When the total volume of an injection is relatively large for a specific site, dividing it into smaller volumes and administering them separately is a safer practice to prevent discomfort, tissue damage, or absorption issues. Giving the medication in the ventrogluteal site can be appropriate for IM injections but does not address the issue of the total volume being too high for a single injection. Calling to get a smaller volume ordered may delay treatment and is not necessary when a safe administration method is available. Checking with the pharmacy for a liquid form of the medication does not directly address the issue of the total volume being too high for a single injection, and changing the formulation may not be necessary if the correct administration technique can be applied.
