Nursing Elites

1. Your pediatric patient weighs 15.8 kg. How many pounds does this child weigh?

• A. 36 pounds
• B. 33.6 pounds
• C. 35 pounds
• D. 34.8 pounds

Correct answer: D

Rationale: To convert 15.8 kg to pounds, you multiply by the conversion factor of 2.20462. So, 15.8 kg * 2.20462 = 34.8 pounds. Therefore, the child weighs 34.8 pounds. Choice A is incorrect as it is higher than the correct answer. Choice B is incorrect as it is lower than the correct answer. Choice C is incorrect as it rounds down the conversion result, leading to an inaccurate weight measurement.

2. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

• A. ST depression
• B. Inverted T wave
• C. Prominent U wave
• D. Tall peaked T waves

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

3. Select the stage of shock that is accurately paired with its characteristic.

• A. The initial stage of shock: Hyperventilation occurs and the blood pH rises.
• B. The compensatory stage of shock: Hypoxia occurs and lactic acid rises.
• C. The progressive stage of shock: Histamine is released; fluid and proteins leak into surrounding tissues and the blood thickens.
• D. The refractory stage of shock: Potassium ions leak out; sodium ions build up, and metabolic acidosis increases.

Correct answer: C

Rationale: The progressive stage of shock is accurately described as the stage where histamine is released, leading to fluid and proteins leaking into surrounding tissues and the blood thickening. In this stage, the body's compensatory mechanisms are overwhelmed, resulting in a cascade of events that worsen the shock state. Choice A is incorrect as hyperventilation and a rise in blood pH are more characteristic of the compensatory stage. Choice B is incorrect as hypoxia and a rise in lactic acid are more typical of the progressive stage. Choice D is incorrect as the described electrolyte imbalances and metabolic acidosis are more aligned with the refractory stage of shock.

4. A nurse is assessing a client with a suspected diagnosis of hypocalcemia. Which of the following clinical manifestations would the nurse expect to note in the client?

• A. Twitching
• B. Positive Trousseau's sign
• C. Hyperactive bowel sounds
• D. Hyperactive deep tendon reflexes

Correct answer: A

Rationale: The correct answer is A: Twitching. Hypocalcemia often presents with neuromuscular irritability, leading to manifestations such as twitching. Trousseau's sign is actually a positive indicator of hypocalcemia, not negative, making choice B incorrect. Hypoactive bowel sounds are not typically associated with hypocalcemia, making choice C incorrect. Similarly, hypoactive deep tendon reflexes are not a common finding in hypocalcemia, making choice D incorrect.

5. Which preventive measure can be employed to decrease the risk of compartment syndrome?

• A. The administration of a potassium-sparing diuretic for heart failure
• B. A bivalve cast for a skeletal fracture
• C. A cerebral diuretic to decrease intracranial pressure after a head injury
• D. A chest tube to restore normal intrathoracic pressure after a pneumothorax

Correct answer: B

Rationale: The correct answer is B. A bivalve cast can help decrease the risk of compartment syndrome by providing space for swelling, thus preventing the build-up of pressure within the muscles. Choices A, C, and D are incorrect because they are not directly related to preventing compartment syndrome. Choice A is more focused on managing heart failure, choice C on reducing intracranial pressure, and choice D on restoring intrathoracic pressure after a pneumothorax, which are not relevant to preventing compartment syndrome.
