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 in respiratory distress who is on oxygen is being cared for by a nurse. What is the most appropriate short-term goal?

• A. Nasal cannula remains in place
• B. Client completes morning care
• C. Client verbalizes breathing improvement after lunch
• D. Client maintains oxygen saturation of 90% during the shift

Correct answer: D

Rationale: The correct answer is D because maintaining oxygen saturation of 90% is a specific, measurable short-term goal that ensures adequate oxygenation. Choice A is not a goal focused on the client's physiological status but rather on the equipment. Choice B is related to activities of daily living and does not address the respiratory distress issue. Choice C is subjective and may not reflect the actual physiological improvement in the client's condition.

3. A client with Ménière’s disease is experiencing episodes of vertigo. Which of the following interventions should the nurse include in the plan?

• A. Encourage bed rest
• B. Restrict fluid intake to the morning hours
• C. Administer aspirin
• D. Provide a low sodium diet

Correct answer: D

Rationale: The correct intervention for a client with Ménière’s disease experiencing vertigo is to provide a low sodium diet. Limiting sodium helps to reduce fluid retention, which in turn decreases the manifestations of Ménière’s disease. Encouraging bed rest (Choice A) may be necessary during acute episodes but is not a long-term solution. Restricting fluid intake (Choice B) to the morning hours does not specifically address the underlying issue of fluid retention associated with Ménière’s disease. Administering aspirin (Choice C) is not recommended for Ménière’s disease as it can worsen symptoms.

4. A healthcare provider is among the first responders to a mass-casualty incident and does not know what type of personal protective equipment (PPE) is needed. Which of the following actions should the healthcare provider take?

• A. Use basic gloves and a mask.
• B. Choose the highest level of protection equipment available.
• C. Use only respiratory protection.
• D. Ask a colleague for advice.

Correct answer: B

Rationale: In situations where the type of hazard is unknown, the healthcare provider should choose the highest level of protection equipment available. This helps ensure adequate protection against any potential hazards that may be present. Using only basic gloves and a mask (Choice A) may not provide sufficient protection if the hazard is more severe. Opting for respiratory protection only (Choice C) may leave other areas of the body vulnerable to exposure. While asking a colleague for advice (Choice D) is good practice in general, in urgent situations like mass-casualty incidents with unknown hazards, it is crucial to prioritize immediate protection by selecting the highest level of PPE.

5. A nurse is caring for a client who is in active labor. The nurse notes early decelerations in the FHR on the fetal monitor tracing. The nurse should identify that which of the following conditions causes early decelerations in the FHR?

• A. Fetal hypoxemia
• B. Cord compression
• C. Uteroplacental insufficiency
• D. Head compression

Correct answer: D

Rationale: Early decelerations are caused by head compression during contractions, which is a normal response as the fetal head is being compressed during uterine contractions. This usually indicates that the fetus is descending into the birth canal. Choices A, B, and C are incorrect. Fetal hypoxemia, cord compression, and uteroplacental insufficiency typically present with variable or late decelerations on the fetal heart rate tracing, not early decelerations.
