Nursing Elites

1. What is the most common cause of HHNS?

• A. Insulin overdose
• B. Removal of the adrenal gland
• C. Undiagnosed, untreated hyperpituitarism
• D. Undiagnosed, untreated diabetes mellitus

Correct answer: D

Rationale: The correct answer is D: Undiagnosed, untreated diabetes mellitus. Hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is most commonly caused by undiagnosed and untreated diabetes mellitus. Insulin overdose (Choice A) is not a typical cause of HHNS; it is more related to hypoglycemia. Removal of the adrenal gland (Choice B) can lead to adrenal insufficiency but is not a common cause of HHNS. Undiagnosed, untreated hyperpituitarism (Choice C) is not a usual cause of HHNS; it is more related to pituitary hormone imbalances rather than hyperglycemia.

2. 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.

3. A patient is admitted to the emergency department with hypovolemia. Which IV solution should the nurse anticipate administering?

• A. 3% sodium chloride
• B. 10% dextrose in water
• C. 0.45% sodium chloride
• D. Lactated Ringer's solution

Correct answer: D

Rationale: Lactated Ringer's solution is the most suitable IV solution for a patient with hypovolemia. It is a balanced crystalloid solution containing electrolytes such as sodium, chloride, potassium, calcium, and lactate, which closely resemble the body's natural fluids. This solution helps to restore intravascular volume and electrolyte balance in hypovolemic patients. Choice A, 3% sodium chloride, is a hypertonic solution used for specific situations like severe hyponatremia or cerebral edema, not typically for hypovolemia. Choice B, 10% dextrose in water, is a hypertonic solution primarily used for providing calories and free water, not for volume expansion. Choice C, 0.45% sodium chloride, is a hypotonic solution used for conditions like hypernatremia or as maintenance fluid, not for hypovolemia.

4. A nurse in a prenatal clinic is caring for a group of clients. Which of the following clients should the nurse recommend for further evaluation and possible intervention?

• A. A client who is at 28 weeks gestation and has a negative Coombs titer
• B. A client who is 39 weeks of gestation and has a negative contraction stress test
• C. A client who is at 35 weeks of gestation and has a biophysical profile of 6
• D. A client who is at 37 weeks of gestation and has an L/S ratio of 2:1

Correct answer: C

Rationale: A biophysical profile of 6 at 35 weeks of gestation indicates a need for further evaluation and possible intervention. A negative Coombs titer at 28 weeks gestation (Choice A) is within normal limits. A negative contraction stress test at 39 weeks gestation (Choice B) is expected as the pregnancy nears term. An L/S ratio of 2:1 at 37 weeks of gestation (Choice D) is consistent with fetal lung maturity.

5. A nurse is assessing an older adult client who was brought to the emergency department by his son, who reports that the client fell at home. The nurse suspects elder abuse. Which of the following actions should the nurse take?

• A. File an incident report.
• B. Ask the client about his injuries with the son present.
• C. Ask the client's son to go to the waiting area.
• D. Treat and discharge the client

Correct answer: C

Rationale: The correct action for the nurse to take is to ask the client's son to go to the waiting area. This allows the nurse to interview the client independently to assess for signs of elder abuse without the son's potential influence. Filing an incident report may be necessary later but is not the immediate action required. Asking about injuries with the son present could lead to biased responses or intimidation. Treating and discharging the client without addressing the suspicion of elder abuse would neglect the nurse's responsibility to ensure the client's safety.
