Nursing Elites

1. 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.

2. 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.

3. 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.

4. A healthcare provider is caring for a client who has anorexia nervosa. Which of the following interdisciplinary team members should be consulted in regards to client care?

• A. Occupational therapist
• B. Case manager
• C. Nutritionist
• D. Psychiatrist

Correct answer: B

Rationale: A case manager is the most appropriate interdisciplinary team member to consult for a client with anorexia nervosa. They can help coordinate care, resources, and communication between various healthcare professionals involved in the client's treatment. Consulting an occupational therapist (Choice A) may not directly address the primary concerns associated with anorexia nervosa. While nutritional therapists (Choice C) play a role in addressing nutritional needs, a case manager is better suited for overall care coordination. Mental health counselors (Choice D) focus more on emotional and psychological aspects, whereas a case manager coordinates practical aspects of care.

5. During which stage of anesthesia is a patient most likely to experience involuntary motor activity?

• A. Stage I
• B. Stage II
• C. Stage III
• D. Stage VI

Correct answer: B

Rationale: The correct answer is Stage II. During Stage II of anesthesia, a patient is most likely to experience involuntary motor activity. This stage is known as the excitement stage, where the patient may exhibit purposeful or involuntary movements. Choice A (Stage I) is incorrect because Stage I is the induction phase where the patient is transitioning from consciousness to unconsciousness, and involuntary motor activity is less likely to occur. Choice C (Stage III) is incorrect as it is the stage of surgical anesthesia characterized by muscle relaxation, and involuntary motor activity is less common during this stage. Choice D (Stage VI) is incorrect as there is no Stage VI in the standard stages of anesthesia. Therefore, the most appropriate stage where involuntary motor activity is likely to occur is Stage II.
