Nursing Elites

1. The nurse practicing in a maternity setting recognizes that the postmature fetus is at risk due to:

• A. Excessive fetal weight
• B. Low blood sugar levels
• C. Depletion of subcutaneous fat
• D. Progressive placental insufficiency

Correct answer: D

Rationale: A postmature or postterm pregnancy occurs when a pregnancy exceeds the typical term of 38 to 42 weeks. In this situation, the fetus is at risk due to progressive placental insufficiency. This occurs because the placenta loses its ability to function effectively after 42 weeks. The accumulation of calcium deposits in the placenta reduces blood perfusion, oxygen supply, and nutrient delivery to the fetus, leading to potential growth problems. Choices A, B, and C are incorrect because excessive fetal weight, low blood sugar levels, and depletion of subcutaneous fat are not the primary risks associated with postmature fetuses. The main concern lies in the compromised placental function and its impact on fetal well-being.

2. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

• A. External light sources may cause falsely high oximetry values
• B. A bright light in the client's face may cause a low pulse oximetry
• C. External light sources may cause falsely low oximetry values
• D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

3. Which example best describes a nurse who exhibits moral courage?

• A. A nurse feels angry when a parent refuses important treatment for his child.
• B. A nurse considers seeking help for depression when she feels she cannot meet the needs of her clients in the oncology unit.
• C. A nurse contacts a physician for further orders when he fails to order comfort measures for a client with a terminal illness.
• D. A nurse is frustrated when the laboratory is slow in responding to an order for a stat blood glucose.

Correct answer: C

Rationale: Moral courage involves taking action to do what is right, even when there might be negative consequences. The nurse who contacted a physician for further orders acted as a client advocate to seek help, even though she may have faced consequences such as lost time, decreased productivity, or criticism from the physician. Choices A, B, and D do not directly involve advocating for a client's needs or challenging a situation that goes against ethical standards. Feeling angry, seeking help for personal issues, or being frustrated with work processes do not necessarily demonstrate moral courage in the context of nursing practice.

4. Which is a physical, integumentary risk among the elderly population?

• A. Skin tears
• B. Thickened skin
• C. Thinning toe nails
• D. Less nasal hair

Correct answer: A

Rationale: Skin tears are a physical integumentary risk among the elderly population. As individuals age, their skin becomes thinner and more fragile, making them susceptible to skin tears. Thickened skin, thinning toenails, and reduced nasal hair are common age-related changes but do not pose the same level of risk as skin tears. Thickened skin may provide some protection, thinning toenails are primarily a cosmetic concern, and reduced nasal hair does not typically lead to significant health risks.

5. A client has a right-sided chest tube with 50 cc of serosanguinous fluid in the collection chamber and air bubbles are collecting in the water seal chamber. What is the most appropriate action for the nurse to take at this time?

• A. Do nothing; this is a normal response
• B. Strip the tubing to remove any clots
• C. Place a clamp on the tube near the client's chest
• D. Remove the collection chamber and connect the tubing to a new device

Correct answer: C

Rationale: The water seal of a chest tube acts as a one-way valve. Air bubbles in the water seal indicate a leak between the client and the chamber. The nurse should briefly clamp the tube near the client's chest to locate the source of the leak. Once identified, the nurse should unclamp the tubing and notify the physician immediately. Choice A is incorrect because air bubbles in the water seal chamber are not a normal finding and indicate a leak. Choice B is incorrect as stripping the tubing could aggravate the issue and is not the initial appropriate action. Choice D is incorrect as it does not address the immediate need to locate and address the leak.
