Nursing Elites

1. With a breech presentation, the nurse must be particularly alert for which of the following?

• A. quickening
• B. ophthalmia neonatorum
• C. pica
• D. prolapsed umbilical cord

Correct answer: D

Rationale: With a breech presentation, the nurse must be particularly alert for a prolapsed umbilical cord. Prolapsed umbilical cord is a critical emergency situation where the umbilical cord descends into the vagina before the fetal presenting part, leading to compression between the presenting part and the maternal pelvis. This compression can compromise or completely cut off fetoplacental perfusion, endangering the fetus. Immediate delivery should be attempted to save the fetus. Quickening refers to fetal movements felt by the mother, ophthalmia neonatorum is an eye infection in newborns, and pica is a condition characterized by cravings for non-nutritive substances, none of which are directly related to the risks associated with a breech presentation and prolapsed umbilical cord.

2. How can a diet high in fiber content benefit an individual?

• A. aid in weight loss.
• B. reduce diabetic ketoacidosis.
• C. lower cholesterol.
• D. reduce the need for folate.

Correct answer: C

Rationale: A diet high in fiber content can help lower cholesterol levels by reducing the absorption of cholesterol in the bloodstream. Fiber-rich foods, like grains, apples, potatoes, and beans, can aid in this process. While fiber can aid in weight loss by promoting a feeling of fullness and aiding digestion, it is not primarily for fast weight loss. Fiber does not directly reduce the risk of diabetic ketoacidosis, which is more related to managing blood sugar levels through insulin therapy and dietary control. Folate is a B vitamin that is essential for various bodily functions and is not influenced by fiber intake. Therefore, the correct answer is to lower cholesterol, as fiber plays a significant role in this benefit.

3. A healthcare professional is reviewing a patient's serum glucose levels. Which of the following scenarios would indicate abnormal serum glucose values for a 30-year-old male?

• A. 70 mg/dL
• B. 55 mg/dL
• C. 110 mg/dL
• D. 100 mg/dL

Correct answer: B

Rationale: The correct answer is 55 mg/dL. The standard range for serum glucose levels is typically 60-115 mg/dL. A serum glucose level of 55 mg/dL falls below this range, indicating hypoglycemia. Options A, C, and D are within the standard range for serum glucose levels and would not be considered abnormal for a 30-year-old male.

4. The client asked about the role of leptin in the body. Which response should the nurse provide?

• A. It increases food intake in clients, thereby promoting obesity.
• B. It assists in the regulation of steroids.
• C. It increases the total fat mass of people who are obese.
• D. It might decrease the total fat mass in the bodies of people who are obese.

Correct answer: D

Rationale: Leptin is a protein hormone expressed in fat cells that regulates fat cell percentage in the body. It is associated with increased energy expenditure and decreased food intake through hypothalamic control. In obese individuals, there may be insensitivity or resistance to leptin's effects. Leptin influences other hormones like insulin and genetic factors related to fat regulation. Therefore, the correct response is that leptin might decrease total fat mass in obese individuals as it is involved in energy balance and fat regulation. Choices A, B, and C are incorrect because leptin does not increase food intake or promote obesity; it does not assist in the regulation of steroids, and it does not increase total fat mass in people who are obese.

5. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.
