Nursing Elites

1. What can cause a low pulse oximetry reading?

• A. Hyperthermia
• B. Increased hemoglobin level
• C. Inadequate peripheral circulation
• D. Low altitudes

Correct answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

2. A client with heart failure and a new prescription for furosemide is receiving teaching from a nurse. Which of the following instructions should the nurse include?

• A. Avoid foods high in magnesium
• B. Take furosemide with food
• C. Eat foods that are rich in potassium
• D. Expect a decrease in blood pressure

Correct answer: C

Rationale: The correct instruction the nurse should include is to advise the client to eat foods that are rich in potassium. Furosemide is a loop diuretic that can cause the loss of potassium, leading to hypokalemia. Eating foods high in potassium can help prevent this electrolyte imbalance. Choice A is incorrect because furosemide does not directly interact with magnesium. Choice B is incorrect because furosemide is usually taken in the morning to prevent nighttime diuresis. Choice D is incorrect because furosemide is a diuretic that typically leads to a decrease in blood pressure rather than an increase.

3. A nurse is caring for a client prescribed prednisone. Which of the following should the nurse monitor?

• A. Blood glucose levels
• B. Serum potassium levels
• C. Liver function tests
• D. Heart rate

Correct answer: A

Rationale: Corrected Rationale: Prednisone is known to cause hyperglycemia by increasing blood glucose levels. Monitoring blood glucose levels is crucial to detect and manage any potential hyperglycemic effects of prednisone. While prednisone can also affect serum potassium levels and liver function, the priority monitoring parameter in this case is blood glucose levels. Monitoring heart rate is not directly associated with prednisone administration, making it a less relevant parameter to monitor in this scenario.

4. A nurse is assessing a 2-hour-old newborn for cold stress. Which of the following findings should the nurse expect?

• A. Respiratory rate of 60/min
• B. Jitteriness of the hands
• C. Diaphoresis
• D. Bounding peripheral pulses

Correct answer: B

Rationale: The correct answer is B: Jitteriness of the hands. Jitteriness is a key sign of cold stress in a newborn, indicating the need for immediate warming measures. A respiratory rate of 60/min may not be directly indicative of cold stress. Diaphoresis (excessive sweating) and bounding peripheral pulses are not typical findings associated with cold stress in newborns.

5. A nurse is caring for a client who has breast cancer and has been receiving chemotherapy. Which of the following laboratory values should the nurse report to the provider?

• A. WBC 3,000/mm3
• B. Hemoglobin 14 g/dL
• C. Platelets 250,000/mm3
• D. aPTT 30 seconds

Correct answer: A

Rationale: A WBC count of 3,000/mm3 indicates neutropenia, a dangerous complication of chemotherapy that increases the risk of infection and requires immediate attention. Neutropenia is a common side effect of chemotherapy and can lead to life-threatening infections. Reporting a low WBC count is crucial to ensure timely intervention. Choices B, C, and D are within normal ranges and do not pose immediate risks to the client undergoing chemotherapy.
