Sublingual nitroglycerin is administered to a male client with unstable angina who complains of crushing chest pain. Five minutes later the client becomes nauseated, and his blood pressure drops to 60/40. Which intervention should the nurse implement?
- A. Administer a second dose of nitroglycerin.
- B. Infuse a rapid IV normal saline bolus.
- C. Begin external chest compressions.
- D. Give a PRN antiemetic medication.
Correct Answer: B
Rationale: In this scenario, the client's symptoms of nausea and a significant drop in blood pressure suggest a potential right ventricular infarction. The appropriate intervention for this situation is to infuse a rapid IV normal saline bolus. This fluid resuscitation helps improve cardiac output by increasing preload, which can be beneficial in right ventricular infarction. Administering a second dose of nitroglycerin may further lower blood pressure. External chest compressions are not indicated in this case as the client has a pulse. Providing an antiemetic medication does not address the underlying issue of hypotension and potential right ventricular involvement.

A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?
- A. International Normalized Ratio (INR)
- B. Prothrombin time (PT)
- C. Serum sodium level
- D. Hemoglobin level of 12 g/dl
Correct Answer: A
Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range to prevent both bleeding and clotting events. Choices B, C, and D are incorrect because while PT is used to monitor warfarin therapy, INR is a more precise indicator of therapeutic levels. Serum sodium level and hemoglobin level are not directly related to monitoring warfarin therapy.
During the initial newborn assessment, the nurse finds that a newborn's heart rate is irregular. Which intervention should the nurse implement?
- A. Notify the pediatrician immediately.
- B. Teach the parents about congenital heart defects.
- C. Document the finding in the infant's record.
- D. Apply oxygen via nasal cannula at 3 L/min.
Correct Answer: C
Rationale: The correct intervention when a nurse finds an irregular heart rate in a newborn is to document the finding in the infant's record. An irregular heart rate is a common occurrence in newborns and does not necessarily require immediate medical intervention. Notifying the pediatrician immediately is unnecessary unless there are other concerning symptoms. Teaching the parents about congenital heart defects is not the priority in this situation. Applying oxygen via nasal cannula at 3 L/min is not indicated for an irregular heart rate without further assessment or medical indication.
The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?
- A. Serum potassium level
- B. Hemoglobin level
- C. White blood cell count
- D. Serum sodium level of 135 mEq/L
Correct Answer: A
Rationale: The correct answer is A: Serum potassium level. In clients receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin therapy can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium levels helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant for assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical due to the potential adverse effects of elevated potassium levels in CKD patients on this therapy.
Before preparing a client for the first surgical case of the day, a part-time scrub nurse asks the circulating nurse if a 3-minute surgical hand scrub is adequate preparation for this client. Which response should the circulating nurse provide?
- A. Ask a more experienced nurse to perform that scrub since it is the first time of the day
- B. Validate the nurse is implementing the OR policy for surgical hand scrub
- C. Inform the nurse that hand scrubs should be 3 minutes between cases.
- D. Direct the nurse to continue the surgical hand scrub for a 5-minute duration.
Correct Answer: D
Rationale: The correct answer is to direct the nurse to continue the surgical hand scrub for a 5-minute duration. Surgical hand scrubs should last for 5 to 10 minutes, ensuring thorough cleaning and disinfection. Choice A is incorrect because the nurse should be guided to complete the scrub properly rather than having someone else do it. Choice B is incorrect as it does not address the duration of the hand scrub. Choice C is incorrect as it suggests a 3-minute hand scrub is sufficient, which is inadequate for proper preparation before surgery.
A client with chronic heart failure is admitted with shortness of breath and a new onset of confusion. Which intervention should the nurse implement first?
- A. Obtain a neurological assessment.
- B. Administer oxygen therapy.
- C. Monitor the client's urine output.
- D. Obtain an electrocardiogram (ECG).
Correct Answer: A
Rationale: The correct answer is to obtain a neurological assessment. In a client with chronic heart failure presenting with confusion, the priority is to assess neurological status to rule out potential causes such as hypoxia or other complications. Administering oxygen therapy (Choice B) is important but assessing the neurological status takes precedence in this scenario. Monitoring urine output (Choice C) and obtaining an ECG (Choice D) may be necessary but are not the initial priority when a client presents with confusion alongside shortness of breath.
