Nursing Elites

1. 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.

2. Most water leaves the body by way of the:

• A. Lungs
• B. Intestines
• C. Skin
• D. Kidneys

Correct answer: D

Rationale: Most water leaves the body through the kidneys. The kidneys play a crucial role in filtering waste and excess substances from the blood to form urine, which is then excreted out of the body. Choices A, B, and C are incorrect because while a small amount of water can be lost through respiration, feces, and sweating, the primary organ responsible for regulating water balance and excretion is the kidneys.

3. Select the cranial nerve that is accurately paired with its name.

• A. The fourth cranial nerve: The trochlear nerve
• B. The twelfth cranial nerve: The hypoglossal nerve
• C. The tenth cranial nerve: The olfactory nerve
• D. The thirteenth cranial nerve: The auditory nerve

Correct answer: B

Rationale: The twelfth cranial nerve is the hypoglossal nerve, which controls the muscles of the tongue. The other choices are incorrect because the trochlear nerve is the fourth cranial nerve responsible for eye movement, the olfactory nerve is the first cranial nerve responsible for the sense of smell, and there are only twelve cranial nerves, so there is no thirteenth cranial nerve.

4. A healthcare professional is reviewing a client's laboratory report and notes that the serum calcium level is 4.0 mg/dL. The healthcare professional understands that which condition most likely caused this serum calcium level?

• A. Prolonged bed rest
• B. Renal insufficiency
• C. Hyperparathyroidism
• D. Excessive ingestion of vitamin D

Correct answer: A

Rationale: Prolonged bed rest can lead to hypocalcemia due to decreased mobility and bone resorption. In this scenario, the low serum calcium level of 4.0 mg/dL is likely a result of decreased bone activity and calcium release due to prolonged bed rest. Renal insufficiency would more likely lead to hypercalcemia due to impaired excretion of calcium by the kidneys. Hyperparathyroidism is characterized by increased calcium levels as a result of excess parathyroid hormone. Excessive ingestion of vitamin D can cause hypercalcemia by increasing intestinal absorption of calcium.

5. Who should document care?

• A. The LPNs should document the care that they provided and the care that was given by unlicensed assistive staff.
• B. The registered nurse must document all of the care that is provided by the nursing assistants because they are accountable for all care.
• C. All staff members should document all of the care that they have provided.
• D. All staff should document all of the care that they have provided but the registered nurse, as the only independent practitioner, signs it.

Correct answer: C

Rationale: All staff members should document the care they provided as part of their accountability and to ensure accurate and comprehensive records. In healthcare settings, it is essential for all staff to document the care they deliver for continuity of care and legal purposes. The registered nurse may sign off on the documentation for oversight purposes, but the responsibility of documenting care extends to all staff involved in patient care. Choices A and B incorrectly limit the responsibility to specific roles, while choice D inaccurately suggests that only the registered nurse signs off on the documentation, overlooking the importance of comprehensive documentation by all staff members involved.
