Nursing Elites

1. A client was admitted for a myocardial infarction and cardiogenic shock 2 days ago. Which laboratory test result should a nurse expect to find?

• A. Blood urea nitrogen (BUN) of 52 mg/dL
• B. Creatinine of 2.3 mg/dL
• C. BUN of 10 mg/dL
• D. BUN/creatinine ratio of 8:1

Correct answer: A

Rationale: In cardiogenic shock, decreased renal perfusion leads to an elevated BUN. Choice A is correct. Creatinine remains normal in cardiogenic shock as it signifies kidney damage, which has not occurred in this case. A low BUN indicates overhydration, malnutrition, or liver damage, which are not typically seen in cardiogenic shock. A low BUN/creatinine ratio is associated with fluid volume excess or acute renal tubular acidosis, not specifically indicative of cardiogenic shock.

2. A client in the postanesthesia care unit has an as-needed prescription for ondansetron (Zofran). Which of the following occurrences would prompt the nurse to administer this medication to the client?

• A. Paralytic ileus
• B. Incisional pain
• C. Urine retention
• D. Nausea and vomiting

Correct answer: D

Rationale: The correct answer is D: Nausea and vomiting. Ondansetron is an antiemetic used to manage postoperative nausea and vomiting, as well as nausea and vomiting related to chemotherapy. It is not indicated for treating paralytic ileus, incisional pain, or urine retention. Paralytic ileus is a condition of the gastrointestinal tract characterized by the paralysis of intestinal muscles, which would not be treated with ondansetron. Incisional pain is typically managed with analgesics, not antiemetics. Urine retention is a urinary issue that does not involve nausea and vomiting, making ondansetron an inappropriate choice for this condition.

3. A client taking furosemide (Lasix) reports difficulty sleeping. What question is important for the nurse to ask the client?

• A. What dose of medication are you taking?
• B. Are you eating foods rich in potassium?
• C. Have you lost weight recently?
• D. At what time do you take your medication?

Correct answer: D

Rationale: The nurse needs to determine at what time of day the client takes the Lasix. Due to the diuretic effect of Lasix, clients should take the medication in the morning to prevent nocturia, which may be contributing to the sleep difficulties. Asking about the dose of medication (Choice A) is important but addressing the timing of intake is more crucial in this situation. Inquiring about potassium-rich foods (Choice B) is relevant for clients on potassium-sparing diuretics. Weight loss (Choice C) may be relevant for monitoring the client's overall health but is not directly related to the sleep issue in this case.

4. A client with chronic obstructive pulmonary disease (COPD) who is beginning oxygen therapy asks the nurse why the flow rate cannot be increased to more than 2 L/min. The nurse responds that this would be harmful because it could:

• A. Be drying to nasal passages
• B. Decrease the client’s oxygen-based respiratory drive
• C. Increase the risk of pneumonia due to drier air passages
• D. Decrease the client’s carbon dioxide–based respiratory drive

Correct answer: B

Rationale: Increasing the oxygen flow rate beyond 2 L/min for a client with COPD can decrease the client's oxygen-based respiratory drive. In clients with COPD, the natural respiratory drive is based on the level of oxygen instead of carbon dioxide, as seen in healthy individuals. Increasing the oxygen level independently can suppress the drive to breathe, leading to respiratory failure. Choices A, C, and D are incorrect because drying of nasal passages, increased risk of pneumonia due to drier air passages, and decreasing the carbon dioxide-based respiratory drive are not the primary concerns associated with increasing the oxygen flow rate in a client with COPD.

5. A 68-year-old client on day 2 after hip surgery has no cardiac history but reports having chest heaviness. The first nursing action should be to:

• A. Inquire about the onset, duration, severity, and precipitating factors of the heaviness.
• B. Administer oxygen via nasal cannula.
• C. Offer pain medication for the chest heaviness.
• D. Inform the physician of the chest heaviness.

Correct answer: A

Rationale: The correct first nursing action when a client reports chest heaviness post-hip surgery is to gather more information through assessment. Inquiring about the onset, duration, severity, and precipitating factors of the heaviness is crucial to determine the cause. This approach helps the nurse to gather essential data to make an informed decision regarding the client's care. Administering oxygen (Choice B) may be indicated based on assessment findings, but it is crucial to assess first. Offering pain medication (Choice C) without further assessment is premature and may mask symptoms. Informing the physician (Choice D) should be done after a thorough assessment to provide comprehensive information for appropriate medical decision-making.
