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 nurse is caring for a client who is receiving oxytocin IV for augmentation of labor. The client’s contractions are occurring every 45 seconds with a duration of 90 seconds, and the fetal heart rate is 170-180/minute. Which of the following actions should the nurse take?

• A. Discontinue the oxytocin infusion
• B. Increase the oxytocin infusion
• C. Decrease the oxytocin infusion
• D. Maintain the oxytocin infusion

Correct answer: A

Rationale: In this scenario, the contractions are too frequent (tachysystole), and the fetal heart rate is elevated. Tachysystole can lead to decreased oxygen perfusion to the fetus, causing fetal distress. Therefore, the correct action for the nurse to take is to discontinue the oxytocin infusion to prevent harm to both the mother and fetus. Increasing or maintaining the oxytocin infusion would exacerbate the current situation, potentially leading to further complications. Decreasing the oxytocin infusion may not be sufficient to address the tachysystole and elevated fetal heart rate, making it an inappropriate choice.

3. A nurse receives a change-of-shift report. Which of the following clients should the nurse attend to first?

• A. A client who reports tingling in the fingers following a thyroidectomy
• B. A client who has dark, foul-smelling urine with a urine output of 320 mL in the last 8 hr
• C. A client who is in a long leg cast and reports cool feet bilaterally
• D. A client who has a productive cough and an oral temperature of 36°C (96.8°F)

Correct answer: C

Rationale: The correct answer is C. Cool feet bilaterally in a client with a long leg cast may indicate compromised circulation, which is a medical emergency that requires immediate intervention. Choices A, B, and D do not present immediate life-threatening conditions. Tingling in the fingers following a thyroidectomy may indicate hypocalcemia but does not require immediate attention. Dark, foul-smelling urine with decreased urine output indicates a possible urinary tract infection or dehydration but can be addressed after attending to the client with compromised circulation. A productive cough and a normal oral temperature do not suggest an urgent condition compared to compromised circulation in a client with a long leg cast.

4. A nurse is assessing a client who has diabetes insipidus and is receiving desmopressin. Which of the following should the nurse monitor?

• A. Fasting blood glucose
• B. Carbohydrate intake
• C. Hematocrit
• D. Weight

Correct answer: D

Rationale: The correct answer is D: Weight. Desmopressin can cause fluid retention, so monitoring the client's weight is crucial to detect signs of water intoxication or overhydration, which can occur with the medication. Monitoring fasting blood glucose (choice A) is not directly related to desmopressin use in diabetes insipidus. Carbohydrate intake (choice B) is important for diabetes management but is not specifically relevant to monitoring desmopressin therapy. Hematocrit (choice C) is not typically influenced by desmopressin use in diabetes insipidus.

5. A nurse is assessing a client who has pericarditis. Which of the following findings is the priority?

• A. Paradoxical pulse
• B. Dependent edema
• C. Pericardial friction rub
• D. Substernal chest pain

Correct answer: A

Rationale: The correct answer is A: Paradoxical pulse. Paradoxical pulse, which is a significant drop in systolic blood pressure during inspiration, indicates cardiac tamponade, a life-threatening complication of pericarditis. This finding requires immediate attention as it suggests potential compromised cardiac function. Choices B, C, and D are associated with pericarditis but do not indicate the same level of urgency as paradoxical pulse.
